Leontopodium alpinum is a globally protected species and a valuable resource for the cosmetic and pharmaceutical industries. This study aimed to evaluate the propagation of edelweiss through ex situ culture, analyzing its morphological and physiological performance under controlled conditions. The morphological and physiological evaluation was carried out by conducting a single-factor experimental design in a controlled environment. A statistical analysis using one-way ANOVA followed by Tukey’s HSD post hoc test (α = 0.05) and Pearson Correlation was performed. There were significant differences between three repetitions of the same cultivar for total leaf number, leaf size category distribution and inflorescence diameter. The correlations between morphological indicators revealed a strong positive correlation between plant width, plant volume, number of inflorescences per stem, and collar diameter on the one hand and between length of the floral stem and number/length of roots on the other. The physiological indicators (estimated transpiration rate, net photosynthetic rate, photosynthetic pigments) suggested a conservative functional and photosynthetic pigment profile. The species’ ability to maintain structural and physiological integrity under controlled conditions reinforces the value of ex situ cultivation as a complementary conservation tool for endangered species and provides a solid basis for valorization programs in commercial crops.

Leopards (Panthera pardus) are considered solitary carnivores, but recent research reveals a more complex lifestyle that incorporates kin selection, hidden social structures, and behavioral innovation and plasticity. This paper combines theoretical advancements in kin selection with empirical findings from the peri-urban Jhalana Forest Reserve in Jaipur, India. Our research demonstrates that kin-tolerant spatial organization, maternal investment, temporal avoidance strategies, and adaptive responses to human-induced pressures form the foundation of leopard ecology in Jhalana. Female philopatry leads to the formation of matrilineal clusters, and maternal strategies play a crucial role in cub survival, with a cumulative two-year survival rate estimated at 61.8%. Emotional behaviors, such as grief-like responses to the loss of cubs, further challenge the notion that leopards are purely solitary animals. These findings have significant implications for evolutionary theory, conservation management, and human–wildlife coexistence. Jhalana serves as a model system where solitude and social behavior intersect, redefining our understanding of leopard ecology and guiding conservation efforts in human-dominated landscapes.

The interaction between humans and birds plays an important role in shaping the sustainability of tropical rainforest ecosystems, particularly through bird vocalizations that function as bioacoustic indicators of ecological conditions while simultaneously embedding socio-cultural meanings within local communities. This study aims to (1) classify types and categories of bird sounds as perceived by rural communities, and (2) assess the role of bird vocalizations as cultural symbols supporting community-based conservation practices. The study was conducted across six islands and eight villages in North Maluku, Eastern Indonesia, using a qualitative approach based on semi-structured interviews and community workshops. A total of 435 respondents, all of whom were farmers residing along forest margins, participated in the study. The results documented 51 bird species belonging to 26 families, whose vocalizations were interpreted and classified by local communities into three acoustic categories: 21 species with loud calls (41.18%), 12 species with melodious calls (23.53%), and 18 species with sad calls (35.29%). Melodious vocalizations were commonly associated with values of beauty, calmness, and social harmony, whereas loud calls were predominantly interpreted as warnings, signals of alertness, or indicators of environmental change. These findings demonstrate that bird sounds serve not merely as ecological cues, but as culturally embedded symbols that guide daily activities, moral values, and conservation ethics within rural communities. By documenting the cultural significance of bird vocalizations across a clearly defined geographic context, this study provides an empirical basis for culturally informed conservation strategies aimed at protecting bird species subject to high levels of cultural use and ecological pressure.

Drought is regarded as the most significant environmental factor affecting the productivity of maize (Zea mays L.) worldwide. The integration of maize landraces, conserved in germplasm bank collections, into elite breeding programs could increase the resilience of modern hybrids to drought and mitigate the genetic erosion identified within the genetic base of cultivated maize. In this study, seeds of fifteen Croatian maize landraces were exposed to four levels of drought stress induced by polyethylene glycol (PEG) to evaluate the effect of drought on their seed germination and seedling root parameters. Analysis of variance revealed significant differences among landraces (G) and applied drought stress treatments (PEG) for all traits, as well as a significant PEG × G interaction for all traits except germination potential. The application of the highest drought stress level, caused by a 20% PEG water solution, reduced germination percentage by 51%, germination potential by 99%, root length by 87%, root diameter by 26%, root area by 91% and root volume by 93% compared to the control. Three landraces, MAK7, MAK11 and MAK15, showing high germination potential, long roots and large root area and volume under drought conditions, were identified as pre-breeding candidates for possible reintroduction into modern breeding programs aimed at increasing drought tolerance. The applied method of PEG-induced drought effectively identified drought-tolerant landraces and can be used for rapid screening of drought tolerance in large numbers of genebank accessions conserved in genebanks.

In August 2023, a large forest fire burned more than 60% of the Dadia–Lefkimi–Soufli Forest National Park in northeastern Greece, following another large fire in 2022. To quantify the effects of these fires on local herpetofauna, we analyzed community composition, abundance, and diversity before and after the 2023 event. Standardized visual encounter surveys were conducted across 29 sites between 2015 and 2024, spanning burned and unburned areas. Species richness, abundance, and diversity metrics, together with Bray–Curtis community dissimilarities, were compared across sampling periods and fire-severity classes. Amphibian assemblages showed high postfire persistence, with 82% of regional species still detected and no significant changes in diversity indices, likely reflecting the buffering role of perennial streams and other hydrologically stable refugia. In contrast, reptile communities showed clear compositional shifts and experienced severe declines: overall reptile species richness decreased to 30% of prefire levels and diversity indices dropped significantly. Tortoises (i.e., Testudo graeca, T. hermanni) declined by nearly 90% relative to prefire estimates, indicating high vulnerability of low-mobility, long-lived species. Snakes were not detected in any burned sites, whereas only a few small-bodied lizards and the freshwater turtle Mauremys rivulata persisted locally. These findings demonstrate that extreme, landscape-scale fires can restructure reptile communities in Mediterranean forests, particularly where long-term habitat change and drought had already reduced population resilience. The study underscores the need for targeted postfire restoration, conservation planning for slow-dispersing taxa, and long-term biodiversity monitoring under increasingly frequent fire regimes.

Mediterranean monk seal (Monachus monachus) sightings along the Lebanese coast were recorded between 2020 and 2025. This study aims to provide insights into the consistency of monk seal presence, their habitat use, and their feeding behaviour in the studied area. The research relied on photographic and video materials gathered from social media reports, as well as contributions from local fishers and divers. A total of 43 sightings were recorded, with photo-identification possible for 34 of these. The study confirmed the presence of at least three distinct individuals, including one adult female frequently utilizing marine caves in Amchit and Rawsheh. Video recordings of feeding behaviour revealed prey species such as grey mullet and octopus, which are also targeted by local fisheries, suggesting potential conflicts between the seals and the fishing sector. This study emphasizes the need for a more systematic, long-term monitoring approach, including the use of infrared cameras, to identify suitable habitats and more accurately assess seal presence. The research further recommends a region-wide effort to understand monk seal movements within the Levantine Basin and to support broader conservation initiatives for the species. Full article

The illegal wildlife trade remains a significant threat to biodiversity in South Africa. The poaching of native species in the country has increased over the years, primarily driven by the demand for abalone, rhino horns, and pangolin scales. This study analysed TRAFFIC wildlife crime records between 1984 and 2025 to identify hotspots, trends in enforcement over time, and the most affected species. We found that provinces such as Gauteng and KwaZulu-Natal have the highest diversity of species affected, while the Western Cape recorded the highest number of incidents, predominantly seizures. Seizure was the most common wildlife activity, followed by poaching and illegal harvesting, with fewer cases of smuggling, breeding, and prosecution. A total of 50 species across nine animal classes were impacted, with white rhinoceros (Ceratotherium simum (Burchell, 1817)), abalone (Haliotis midae (Linnaeus, 1758)), lion (Panthera leo (Linnaeus, 1758)), and ground pangolin (Smutsia temminckii (Smuts, 1832)) among the most frequently targeted. Correlation analysis revealed a strong positive relationship between seizures and arrests (Pearson’s r = 0.90, p = 0.001) across provinces. This indicates a substantial strengthening of law-enforcement activity across provinces, likely driven by enhanced detection or reporting, as reflected in a rising proportion of cases resulting in arrests. Species such as elephants and pangolins were associated with enforcement outcomes, particularly those involving horns, tusks, scales, and dead specimens. There is a need for targeted interventions in high-risk areas, and provinces must collaborate in combating the wildlife trade. Limitations in data completeness and species representation suggest the need for improved surveillance and reporting mechanisms to fully understand and combat illegal wildlife trade in South Africa.

Reconciling carbon (C) sequestration with biodiversity conservation remains a key challenge for sustainable forest management, as C–biodiversity relationships vary across taxa and contexts. We evaluated how botanical composition, forest structure, C pools, and land use predict species richness of insects, birds, and bats across mature temperate forests in southern Québec, Canada. Generalized linear models were fitted for insects and birds, while bat data were analyzed descriptively due to low and uneven richness. Botanical composition and forest structure were the most consistent predictors across groups. Insects responded strongly to vegetation structure and C allocation, with richness decreasing with shrub density and mineral soil C but increasing with the soil:above-ground C ratio and distance from infrastructure. Bird richness increased with herbaceous cover and wetland area, emphasizing the value of open and moist habitats. Across taxa, C pools acted as secondary but complementary predictors. Based on observational analyses, our results show that C–biodiversity relationships are compartment-specific and taxon-sensitive, and suggest that maintaining structural complexity, diverse vegetation strata, wetland habitats, and soil C pools may help align biodiversity conservation with C sequestration objectives in temperate forests.

Increasing community awareness of, and engagement in, biodiversity and nature are key elements in many environmental conservation strategies. However, the public may take little or no action to protect biodiversity even though they may feel a strong sense of concern about its decline. This suggests that, although members of the public may be cognitively and affectively engaged with conserving biodiversity, this engagement does not necessarily translate into behavioural engagement and support for environmental policies. We hypothesised that the association between cognitive and affective engagement with conserving biodiversity on the one hand, and conservation behaviour on the other, depends on the relevance and importance of conserving biodiversity with respect to personal needs. Using a survey of the New Zealand public (n = 1000) we found that engagement with biodiversity was associated with the personal relevance and needs-based importance of conserving biodiversity. Importantly, using conditional process analysis, we found that involvement moderates the link between cognitive and affective engagement and conservation behaviour with the link strengthening as involvement intensifies. These findings help to explain why cognitive and affective engagement with conserving biodiversity do not translate inevitably into behavioural engagement with conserving biodiversity and support for environmental policies. The implication is that, to stimulate action, knowledge and sentiment must be accompanied by the perception that action to protect biodiversity will contribute in significant ways to meeting personal needs.

Anurans are among the most threatened vertebrates worldwide, yet their acoustic ecology in fragmented habitats remains understudied. This research investigated acoustic overlaps and resource partitioning among amphibian species inhabiting Maceira Pond in Caparaó National Park, Brazil using bioacoustic methods. Six hours of recordings were analysed to determine key acoustic parameters and identify the resident species. A principal component analysis was used to assess acoustic parameters, whilst a cluster analysis examined acoustic similarities. Twelve species from four families were detected, of which eight were identified and five remained unidentified. Four species showed over 90% acoustic overlap, while two had less than 50%, with one at about 17%. Central frequency, peak frequency, duration, bandwidth, and pace significantly contributed to call differentiation. The R-value confirmed clustering patterns, indicating likely low acoustic interference due to few sympatric species. This study provides the first acoustic niche assessment for this community and highlights the need for further research on spatial and temporal partitioning in these threatened amphibian assemblages.

The eastern Baltic region is rich in hemiboreal forests, which are both commercially important and provide habitats for rare and/or endangered forest-dwelling species, which are sensitive to accelerating climatic changes. Under the intensifying climatic disturbances that are stressing forests worldwide, sanitary logging is a widely used harvesting technique for the mitigation of commercial losses. The effects of salvage logging on the biodiversity of forests remain ambiguous due to the larger scale and higher intensity of timber harvesting, which can alter the recovery of stands and succession of their vegetation. Furthermore, EU legislation is increasingly emphasizing conservation/restoration and mandating its implementation. The recovery of ecosystems, and hence the biodiversity of disturbed managed forests, can take several decades to centuries, depending on the site conditions. Long-term (~60 years, four remeasurements) changes in the composition and structure of vegetation, as an indicator of overall health and nutrient cycling, were studied in conventionally managed hemiboreal forests. Potential forest transformation (paludification) risks associated with large-scale logging were assessed in mixed coniferous stands in the Baltics, Latvia. Following logging, the stands were conventionally managed, including artificial regeneration. According to ground cover vegetation, 50 years was the period for the disturbance effects to start subsiding, as a dynamic equilibrium was reached and the canopies of regenerating trees were closing. A gradual decrease in moisture levels in the middle parts of salvage-logged areas, and later at their edges, indicated that the stands have escaped paludification, likely as the climate has been warming. Distance from the edge of the salvage-logged areas had a secondary effect on ground cover vegetation recovery after storms, alleviating concerns about the explicit negative impact of the scale of harvesting. Thus, in managed seminatural forest landscapes with a historically small to moderate scale of anthropogenic disturbance, salvage logging at a scale locally deemed as large had a transient effect in the Baltics. This indicates successful regeneration of the forest ecosystem over a timeframe shorter than the conventional rotation period, suggesting overall conservation efficiency of conventionally managed forests. Accordingly, salvage logging can be sustainable in terms of biodiversity and forest continuity in the long run under traditional management, as environmental changes accelerate. Full article

Rapid urban expansion across southwestern Florida has led to extensive habitat fragmentation and degradation, presenting significant ecological challenges for the persistence of multiple species, including the Big Cypress fox squirrel (Sciurus niger avicennia; BCFS), a state threatened and imperiled subspecies endemic to the Big Cypress Basin. This study uses high-resolution ecological modeling, Omniscape, to assess the functional connectivity of BCFS habitat within the urbanizing landscape of Fort Myers, Florida, and a green infrastructure (GI) transect-based approach to identify strategies for improving habitat and connectivity within the urban landscape. Results demonstrate that BCFS movement is disproportionately represented in high-density urban zones, with priority bottleneck patterns emerging in surrounding lower-density, transitional land use areas such as suburban neighborhoods and golf courses. By combining spatial modeling and applied GI design, this study offers a replicable framework for embedding species conservation into local and regional planning processes. Given the model-based and species-specific scope of this study, future research should focus on empirical validation and extending this framework across multiple species and scales. Overall, the findings emphasize the importance of multiscalar, landscape-sensitive planning strategies to mitigate anthropogenic fragmentation, enhance ecological resilience, and support the long-term persistence of native species in rapidly developing regions.

Urban areas worldwide face significant pressure from population growth and urban expansion, resulting in habitat loss. Urban planners need to develop a comprehensive strategy for protecting, restoring and enhancing natural heritage (such as natural features and assets), at the municipal and regional levels. Here, we propose an approach to design a Natural Heritage System (NHS) that interconnects natural features and areas. This resulting NHS aims to guide and prioritize the protection, restoration, and enhancement of ecological areas and their functions. The NHS integrates terrestrial and aquatic ecosystem functions for conservation planning. We leverage the Marxan optimization tool to identify target areas using 36 ecological features. We compare three spatial scenarios: regional-scale, watershed-scale, and a hybrid approach. We found that the hybrid scenario proved to be the most effective, covering 52% of the jurisdiction. Then, we classified the target areas into three tiers of the NHS: (1) existing natural cover (23.4%), (2) potential natural cover (12.3%), and (3) contributing areas (16.3%). Contributing areas represent additional parts of the NHS within developed or partly developed landscapes to support overall NHS health and ecological function. These tiers allow for tailored management actions: protection of existing natural cover and restoration of potential natural cover. Altogether, the areas identified for the NHS by Marxan provide a strong, science-based framework to address urbanization impacts and support long-term implementation of biodiversity and urban sustainability solutions. It also provides enhancement opportunities through green infrastructure in contributing areas using nature-based solutions aiming to conserve biodiversity in urban areas. Full article

Madagascar is a global biodiversity hotspot, with approximately 90% of all its plant and animal species being endemic, most of them associated with forest ecosystems. This rich biodiversity is threatened by relentless deforestation; in 2014 only about 15% of the national territory retained highly fragmented native forests, and deforestation continues with worrying forecasts for the coming decades. This rapid loss of habitat is not only causing species losses, but also the loss of important ecological functions that may disappear well before the extinction of the species involved. Here we want to draw attention to the three species of parrots endemic to Madagascar, for which there is a lack of systematically collected data on their distribution and population trends. We compiled available evidence, including data derived from citizen science, suggesting that the distribution and abundance of at least two of the three parrot species have declined in recent decades. These declines are likely driven not only by forest loss but also by persecution for the pet trade, crop protection, and hunting for food. There is also evidence, although still scarce, showing that these parrot species not only act as plant antagonists, but also fulfill mutualistic functions such as seed dispersal by different mechanisms, pollination, and maintenance of plant health. We urge researchers to study the current distribution and population size of the Malagasy parrots, as well as the full antagonism–mutualism spectrum of relationships with their food plants. This is needed for assessing their current conservation status, which may be significantly worse than that reflected by the IUCN Red List, and for identifying important ecological functions that may be lost before the disappearance of the species involved, which can be key to the maintenance and regeneration of the forests they inhabit.

This study examines a long-term dataset where 16 passerine species, classified as long-distance migrants, short-distance migrants, and residents were monitored at the Santo André National Ringing Station (Portugal) from 1997 to 2024. Using standardized capture data from 16 passerines species collected during the autumn migration period, we evaluated trends in population abundance over a 27-year time span. Our analyses revealed pronounced and statistically robust declines in all long-distance migratory species, particularly savi’s warbler, grasshopper warbler, and sedge warbler, which are now almost locally extinct. In contrast, short-distance migrants and resident species exhibited more heterogeneous patterns depending on their ecological specialization, yet all strictly insectivorous taxa, except for the chiffchaff, showed marked population declines, particularly the bluethroat and the sardinian warbler. The parallel decline in insectivorous species across migratory strategies points to a widespread trophic effect, likely linked to the global depletion of insect populations, driven by habitat destruction, pesticide use, pollution, and climate change. Collectively, these findings emphasize the urgent need for regionally adapted, long-term monitoring programs to inform effective conservation strategies in the face of accelerating climate and land-use change.

This study provides a comprehensive and refined framework for the micropropagation of the critically endangered Greek endemic Silene conglomeratica. Using a limited seed stock, a reliable in vitro propagation protocol was developed, supporting both ex situ conservation and potential commercial applications in floriculture and landscape architecture. Nodal explants excised from aseptic seedlings, established on half-strength Murashige and Skoog (MS) medium, were successfully used for culture initiation. Supplementation with 1.0 mg L⁻¹ meta-topolin (mT) and 0.2 mg L⁻¹ 1-naphthaleneacetic acid (NAA) promoted shoot proliferation. Subsequent subculturing on half-strength Rugini Olive Medium (OM/2) supplemented with 0.5 mg L⁻¹ 2-isopentenyladenine (2iP) resulted in high multiplication rates and a high frequency of spontaneous rooting. Rooting initiation was further optimized using OM/2 supplemented with 0.5 mg L⁻¹ indole-3-butyric acid (IBA). The high acclimatization percentage (80%) confirms the feasibility of this protocol for ex situ conservation and highlights its applicability for nursery production and specialized landscape use. Overall, this study contributes an efficient and scalable propagation strategy that supports both the conservation and sustainable utilization of this valuable endemic species. Future work should focus on refining these protocols through more targeted testing of concentrations and alternative combinations of growth regulators and nutrient compositions. Full article

To establish the best approach for conserving a species, it is necessary to understand the biology of that species. To better understand the behavior of American black bears (Ursus americanus), we observed 246 black bears for 7950 h in nature over a 24-year period to quantify how the bears communicated. Black bears communicated using several different behaviors. These included thirteen types of vocalizations, eight olfactory behaviors, eight marking behaviors, sixteen different body postures and gestures constituting their body language, and various emotional expressions. Some behaviors appeared to be automatic, including facial expression, ear movements, some forms of body language, the intensity of various vocalizations, and various moans. Other behaviors appeared to be intentional, including mechanically generated sounds and actions that could be used to bluff or deceive, such as the chomping of teeth, huffing, swatting, false charging, and various vocalizations. The conservation of black bears can be improved by establishing management strategies that take into account the vocal and non-vocal communication of the bears. Conflicts and negative encounters between humans and bears can be reduced through behavioral modifications by humans based on our new understanding of the communication system of bears. Knowledge of the communication system of the black bear provides a basis for improved conservation through the non-lethal management of bears involved in bear–human conflicts. Full article

The recent recognition of the Neotropical otter (Lontra annectens) as a distinct species highlights the need to evaluate its genetic status and connectivity across fragmented tropical habitats. We analyzed genetic diversity, population structure, and recent demographic patterns of L. annectens from two contrasting regions in northern Costa Rica—Tortuguero National Park (TNP) and the Sarapiquí River Basin (SRB). Non-invasive fecal and anal-gland secretion samples collected during 2021–2022 were genotyped at ten nuclear DNA microsatellite loci. Genetic diversity was moderate across regions (mean allelic richness [AR] = 3.98–4.03, observed heterozygosity [Ho] = 0.52–0.58), expected heterozygosity [He] = 0.62–0.65) with no significant inter-regional differences. Bayesian clustering, principal component analysis, and pairwise F_ST (0.002) supported a near-panmictic population. Kinship analyses detected localized clusters of related individuals, suggesting weak but non-random structuring, while contemporary migration estimates indicated low-frequency, asymmetric gene flow from SRB to TNP. Bottleneck tests revealed signatures of recent demographic contraction in both regions, particularly in TNP. These findings demonstrate limited yet ongoing connectivity among riverine subpopulations and emphasize that increasing habitat fragmentation could erode this exchange. Maintaining hydrological corridors and monitoring genetically vulnerable subpopulations should be conservation priorities to preserve gene flow and long-term viability of L. annectens in northern Costa Rica.

Alpacas thrive in Andean ecosystems, efficiently converting natural pasture into products such as fiber and meat, making their breeding a production alternative in Guamote. Intensive grazing and the shift in the spatial distribution of plants due to climate change negatively impact the moorlands. In this context, this study analyzed the influence of floristic composition on the productivity and quality of natural pastures. The methodology included a floristic inventory in a sample of 98 cells in four communities, collecting flora data using the Parker method to measure species composition, density, and cover. In addition, soil fertility and nutritional quality of desirable pastures were assessed through physical and chemical analyses. Principal component and cluster analyses were then applied to correlate the variables. The results showed 26 species, with Poaceae and Asteraceae standing out as dominant and abundant. Tablillas and Pull Quishuar stood out for their productivity and carrying capacity (4.83 t/ha), while Galte Bisñag showed high protein and plant vitality in their pastures. Component 1 stood out for its high production (3.71 t/ha) and carrying capacity in fertile soils; Axis 2 linked Galte Bisñag with high nutritional quality and vegetation cover, while Axis 3 related Asaraty with compacted soils and an intermediate balance. The direct influence between floral species and the productivity of natural pastures leads to the exploration and implementation of measures for sustainable grazing. Full article

Parassi mullet (Mugil incilis) is an ecologically and economically important species that supports small-scale artisanal fisheries. However, scarce knowledge of its reproductive biology limits the development of management and conservation strategies. This research describes key milt and sperm characteristics, including milt volume, sperm concentration, motility, and ultrastructural features. Males produced an average of 40.0 ± 20 µL of milt, with sperm concentrations between 6.00 and 20.37 × 10⁹ spermatozoa mL⁻¹. Sperm motility varied between 10% and 80%, with a mean duration of 14.13 ± 4.49 min. Mature spermatozoa measured 33.79 ± 0.67 µm and exhibited a subspherical head without an acrosome, a short midpiece, and a cylindrical flagellum. The nucleus contains electron-dense heterogeneous chromatin. The centriolar complex was positioned outside the nuclear fossa consistent with Type II spermiogenesis. The flagellum comprises a main piece and tapering end piece. The axoneme had 9 + 0 arrangement at the basal body region and the typical 9 + 2 configuration along its length. These results provide the first detailed description of sperm morphology in parassi mullet and contribute to an understanding of its reproductive biology, supporting future applications in taxonomy, toxicology, conservation and aquaculture programs.

The brown bear (Ursus arctos) occurs across several regions of Türkiye and occasionally damages beehives near rural settlements. This study examines temporal data and the spatial arrangement of beehive damage incidents recorded in the Ilgaz district of Çankırı, Türkiye during 2023–2024. The temporal data were evaluated across lunar phases. A chi-square test showed that incidents did not distribute evenly. A higher frequency was found during the Waxing Crescent phase. Spatial intensity was mapped using Kernel Density Estimation (KDE), where bandwidth selection followed a cross-validation procedure. KDE results showed clear concentrations of incidents in the southern and southwestern parts of the district, while other areas recorded few or none. A Decision Tree (DT) classifier based on eleven environmental variables was used to identify predictors of incident presence. The DT achieved an AUC of 0.808. It identified “distance to settlement” as the primary separating variable, followed by “distance to road”, “distance to forest”, and the “Human Footprint Index”. Beehive damage followed a non-random temporal pattern across lunar phases. It clustered near settlements. Conflict timing followed both environmental conditions and human activity. The findings provide an empirical basis for reducing apiary losses and improving coexistence measures between local communities and brown bears in the Ilgaz region. Full article

Monitoring the size of wildlife populations is crucial for the effective implementation of conservation management strategies, and a variety of methods have been developed for this purpose. One such approach is the double-observer method, which has recently gained prominence in monitoring programs for the southern greater glider (Petauroides volans), an iconic nocturnal arboreal marsupial native to Australia. While this method has been successfully applied at lower population densities, its reliability and applicability at higher-density sites has not been evaluated. This case study represents the first instance of an investigation and discussion on the application of the double-observer method in greater glider monitoring at higher-density sites. We found that in higher-density areas, the proximity of individuals makes it more difficult to reliably distinguish unique (individual) animals between observers, and the increased number of observations per transect extends the time required for data recording. Transects with more animal observations showed significantly longer delays between observers (z = 5.062, p < 0.001). Additionally, discrepancies in the number of animal observations between observers significantly altered the intended 15–20 min interval (z = 2.71, p = 0.007). Deviations from the standard 15–20 min interval between observers were common, occurring at 44 of the 66 sites, where actual time-lags ranged from 0 to 64 min. Consequently, longer intervals increased the potential for animal movement, while shorter intervals risked observer independence. These factors, combined with our experience applying the double-observer method across sites with markedly different greater glider densities, suggest that the critical non-movement assumption may be violated more frequently than previously recognised. We discuss the limitations of applying the double-observer method to survey high-density populations and recommend prioritising research on greater glider movement patterns and alternative survey techniques to improve the accuracy and reliability of monitoring programs at higher-density sites.

Forests are important biodiversity reservoirs and require sustainable management to prevent deforestation and forest degradation. Forest landscape restoration (FLR) has been proposed as a sustainable initiative aimed at restoring ecosystem functions and improving the well-being of surrounding populations. In 2005, the World Wildlife Fund (WWF) initiated a project to protect 200 ha of savanna in Manzonzi landscape, Democratic Republic of Congo, on the outskirts of the Luki Biosphere Reserve. The biodiversity changes related to this ecological restoration project remain unpublished. To address this knowledge gap, floristic inventories of the protected Manzonzi landscape were carried out over a 12-year period and we assessed how changes in the floral composition of this landscape evolved and affected the provision of ecosystem services (ES). We found that protection of the savanna by banning recurring bush fires and fencing off the area promoted the richness and abundance of forest species, such as Xylopia aethiopica (Dunal) A. Rich, Albizia adianthifolia (Schumach.) W. Wight. These forest taxa replaced grassland species, such as Hymenocardia acida Tul. and Maprounea africana Müll. Arg., and served to benefit the local population, who use these forest taxa as food, fuelwood, and medicines. This study revealed that protected savanna improved woody biomass, plant diversity (richness/abundance), and carbon storage, significantly boosting essential ES for communities; yet these positive trends reversed when active monitoring ceased. Protecting savannas improves the environment and benefits communities, but stopping protection efforts can undo these gains, emphasizing the need for ongoing conservation. Full article

Insufficient investment in wildlife that lacks strong aesthetic or emotional appeal to humans poses a significant obstacle to achieving broader conservation goals. Species that are not considered charismatic are nonetheless vital to ecosystems and deserve attention from conservationists, researchers, and the public. However, effective strategies for bridging the gap between these species and traditionally charismatic ones remain underexplored. Our exploratory study introduced the concept of charisma orientations to examine their influence on pro-bird behaviors, such as following guidelines, reporting disturbances, and participating in community advocacy. We identified six relational and socially negotiated orientations—ecological importance, intrinsic right to exist, protection support, affective meaning, and perceived decline—that together represent key perspectives through which waterbirds are understood. A survey of 615 Texas coastal recreationists revealed that relying solely on positive charisma diminishes the appeal of waterbirds for participants. The species likeability frame was relevant only in the context of reporting disturbances, while a moral policy stance (the belief that waterbirds need protection) was significant in predicting advocacy. Younger males and individuals who felt current regulations were adequate were less likely to engage in waterbird conservation behaviors. Our findings suggest that examining the intersection of contested charismatic species and various charisma orientations can uncover subtle nuances often overlooked due to an overemphasis on positive charisma and emotional resonance, which may only partially apply or not apply at all.

Despite its global distribution, the impacts of wild pigs on the environment are poorly understood. However, wild boar (Sus scrofa) is recognized as a pest species, causes extensive damage to agriculture, biodiversity, and forests, and contributes to motor vehicle accidents. This study investigates the causes and mechanisms underlying the demographic explosion of wild boar in Italy. The analysis is based exclusively on official datasets from Italian governmental institutes, allowing quantitative correlations between population dynamics, culling rates, and economic impacts. By integrating historical data, population biology, reproductive physiology, and chemical communication, the study reveals that anthropogenic pressures, counterintuitively driven by wildlife management practices, have significantly contributed to population growth. A shift from a K-strategy to an r-strategy in reproductive behavior, induced by sustained control pressure, has led to increased birth rates and accelerated expansion. Disruptions in species homeostasis trigger harmful changes in ecosystem structure and functionality, delineating a model of environmental damage. These findings highlight the urgency of adopting an integrated wildlife management approach that combines conservation biology and physiological principles with targeted operational interventions to prevent further degradation affecting both the species and the ecosystem.

Since 2019, the Mexican Government has implemented the Sembrando Vida Program (SVP) to address environmental degradation and social marginalization in rural areas. This research analyzed the SVP’s targeting mechanisms to assess the fulfillment of its objectives in the central region of the state of Guerrero, Mexico. The methodology included an analysis of the Operating Rules; a review of the beneficiary registry; the construction of environmental, social, and economic indicators; proportional stratified sampling with a 90% confidence level; and an SVP evaluation using indicators and confidence intervals. Targeting mechanisms identified agrarian subjects aged ≥ 18 years with 2.5 hectares living below the poverty line. Changes in the indicator matrix highlight a focus on food self-sufficiency and poverty levels, among others. Key results from the indicators include 100% social recovery, 62.3% of beneficiaries increased their agricultural income, and 100% application of learned environmental techniques. The intervals showed that between 26.49–42.19% of individuals joined the agricultural sector; 55.68–71.58% diversified their crops; and 86.15–95.65% made improvements in health, housing, or education. The evaluation of the SVP demonstrated its impact on environmental preservation and the improvement of the socioeconomic well-being of the rural population in the study area. Full article

The necessity of citizen involvement in biodiversity conservation activities is widely recognized in practical conservation operations. Clarifying the roles of annual-fee membership schemes is important, as they enable diverse styles of citizen participation. Kyororo is a museum whose main theme is the Satoyama in snowy regions, and the Kyororo Friends Association is an affiliated annual-fee membership program. This study examines the results of a questionnaire survey distributed among the association’s members to examine their perceptions of Kyororo’s activities, in addition to their characteristics—such as age group, place of residence, and type of involvement—and their motivations for joining the association. This study contributes by revising four potential roles of annual-fee membership in terms of promoting citizen participation. The first is as a platform for citizen involvement that is independent of geographic distance or direct participation. The second is as a platform for sustaining the involvement of individuals who have contributed to the accumulated history of the activities. The third is as platforms for citizens who understand and trust community-level nature, conservation activities, and their values to affiliate with and provide their support. The fourth is as a platform for sustained citizen support through regular fixed-amount payments to trusted entities. Full article

The conservation status of saltscapes can vary. These areas possess their own biodiversity, which can even be stimulated by balanced socio-ecological systems, particularly those where the development of economic activities has a low ecological footprint, as is the case of traditional salt production. This study examined the conservation status of Portuguese saltscapes, related not only to the ancient activity of extracting salt-based products, but also to the more recent emergence of cultural ecosystem services, particularly those related to tourism. Using the concept of socio-ecological systems the methodological approach combines cross-referencing official statistical data with aerial imagery analysis, testing the conservation status of some saltscapes, determining whether traditional salt production areas tended to be regenerated or abandoned. The results showed that, in the main areas related to traditional salt production, conservation of saltscapes has been ongoing in recent years, particularly through the regeneration of several production areas. In some of these salt pan areas, tourism activities have been developed, increasing the resilience of the activity from a socioeconomic perspective. Saltscapes—with a particular focus on the conservation of traditional salt pans—provide ecosystem services that go beyond mere salt extraction, as they are being revalued both ecologically and culturally.

The Eurasian Griffon Vulture (Gyps fulvus) is the most abundant obligate scavenger in Europe. It depends on wild and domestic carcasses whose availability and location are relatively unpredictable in terms of space and time, but also on predictable sources of anthropogenic origin. In this study, satellite and accelerometer data from 10 adult individuals captured in the Basque Country (N Spain) were analysed with the aims of identifying feeding sites and determining the types of resources used. The annual cycle of the species was subdivided into three phases: pre-laying and incubation (December–March), rearing (April–July) and post-rearing (August–November). Our results showed that 64% of trophic resources were consumed in mountain pastures and on extensive or semi-extensive livestock farms, highlighting the importance of these farming systems for the species in the study area. However, 36% of the resources were exploited in more predictable anthropic environments, such as landfills and supplementary feeding stations and, to a much lesser extent, intensive farms. Individual variability was detected in terms of trophic behaviour. On semi-extensive farms, the most consumed carcasses were sheep (48%) and horses (37%), while on intensive farms, it was pigs (81%). During the pre-laying and incubation phase, feeding events detected in landfills were reduced, with vultures focusing on resources close to the colony. We observed that the population studied differed from other Spanish populations in its greater use of trophic resources from extensive and semi-extensive livestock farms, as expected from their spatial-temporal distribution and local availability.

Equine yards represent a substantial yet often overlooked land-use category in Europe, with potential to contribute to biodiversity and environment conservation. This study explored behavioral drivers and barriers to biodiversity implementation on Dutch equine yards using the COM-B model (Capability, Opportunity, Motivation—Behavior). Semi-structured interviews were conducted with 19 yard owners, covering both private and commercial operations ranging from <3 hectares to >3 hectares. Data were analyzed thematically using a deductive COM-B framework, with coded responses quantified to assess the relative weight of barriers and enablers. Reflective motivation emerged as a consistent enabler, grounded in values such as equine welfare, sustainability, and responsible land use. However, barriers were more prevalent overall, particularly within physical and social opportunity. Small yards faced constraints related to time, labor, and land tenure, while larger yards reported challenges integrating biodiversity into routines and navigating regulatory complexity. Psychological capability was not a major constraint, though yard owners expressed a clear need for externally sourced, informed advice. These findings suggest that while motivation is high, structural barriers limit implementation. Unlocking the ecological potential of equine yards will require targeted, size-sensitive policy support, recognition of their land stewardship role, and better integration of biodiversity into daily management practices.
