Equids, primarily horses, are mostly used for recreational purposes, although in some rural areas they also serve as working animals, maintaining close and frequent contact with humans. Their risk of exposure to vector-borne and zoonotic pathogens can be affected by host-related factors, management practices and environmental conditions. This study aimed to investigate the seroprevalence and associated risk factors for infections by Babesia caballi, Toxoplasma gondii, Coxiella burnetii, and Borrelia burgdorferi sensu lato in equids from Southwestern Greece. A total of 159 equids were tested using commercial serological assays. Weighted prevalence estimates were applied to account for unequal sampling. Associations were assessed using chi-square tests and logistic regression. Ecological niche modelling was employed to evaluate geographic patterns and environmental correlates. Seroprevalence was highest for B. caballi (8.81%), followed by T. gondii (7.55%) and C. burnetii (1.26%). No seropositive animals were detected for B. burgdorferi sensu lato. Ecological niche modelling showed acceptable predictive performance for B. caballi, with BIO14 and BIO6 emerging as the main environmental predictors. In contrast, the T. gondii model exhibited unacceptable predictive performance, and its environmental associations should therefore be interpreted cautiously. Complementary Random Forest analyses yielded comparable environmental rankings but showed higher classification performance for T. gondii than for B. caballi. Overall, the findings contribute to understanding pathogen exposure patterns in equids and underscore the importance of integrating epidemiological and environmental data in surveillance efforts.

La Paz Bay is one of the most important destinations for recreational fishing events in Baja California Sur, Mexico, with significant tourist activity that supports ecosystem services and provides economic benefits to participants, benefits that have not yet been economically measured. The aim of this study was to estimate the willingness to pay (WTP) of anglers who participated in sport-fishing events and to propose tourism promotion and recreational fisheries management strategies. Applying 184 face-to-face surveys at sport fishing events in LPB held in 2022 and 2023 to collect information regarding fishers’ and fishing trips characteristics, and using the individual travel cost method to estimate the individual WTP per angler, which ranges from USD 50.96 to 625.63, and the recreational economic value of fishing events in La Paz was estimated at USD 0.89 to 1.11 million. Strategies for conserving species reserved for sport fishing and promoting tourism are discussed, which could help improve tournament activity and promote the rational use of natural resources. This study represents the first effort aiming to value sport fishing events in Mexico. Also, demonstrates the economic relevance of sport fishing events for recreational fisheries management and tourism-promoting policies in LPB. It provides evidence that conserving sport-fishing species could enhance management strategies and sustainable tourism promotion policies for this recreational activity. Full article

Microplastic contamination is a growing environmental concern in coastal ecosystems, particularly on recreational beaches where human activities may influence plastic inputs. This study investigated microplastic abundance and particle characteristics across five recreational zones along Hatwanakorn Beach in the Gulf of Thailand, focusing on fine-scale variability within a spatially continuous beach system and across management regimes. Supratidal sediments were collected using a quadrat-based approach, and polymer types were identified using Fourier Transform Infrared spectroscopy (FTIR). Fibers were the predominant particle type, followed by fragments, and most particles were classified as large microplastics (1–5 mm). Significant spatial differences in abundance were observed among recreational zones (Kruskal–Wallis test, χ² = 13.37, p = 0.0096). At the management regime scale, a negative binomial generalized linear model also indicated significant differences (χ² = 30.58, p < 0.001), with higher abundance in the Hatwanakorn Forestry Research and Student Training Station (HWK Station) and Community regimes than in the National Park regime. These results indicate that microplastic distribution can be spatially heterogeneous even within a continuous recreational beach system, underscoring the importance of accounting for fine-scale spatial variability when assessing microplastic contamination in coastal environments.

This study examines the transformation of environmental governance processes in recreational tourism in Turkey and Lithuania through artificial intelligence (AI)-supported waste management applications. The research focuses on the contributions of AI-based applications to sustainable destination management, environmental sustainability, and data-driven governance processes. A case study design was used within the framework of qualitative research methods. The dataset was obtained through semi-structured interviews with a total of 40 experts from Turkey and Lithuania. The data were analyzed using content analysis with the NVivo 14 program. The research findings reveal significant differences between the two countries in terms of digital infrastructure, institutional coordination, governance structures, and AI integration capacity. In Turkey, AI-supported waste management applications are still in their development phase; processes are largely shaped by managerial initiative, project-based approaches, financial constraints, and lack of institutional coordination. In contrast, Lithuania exhibits a more systematic and institutionalized digital governance structure thanks to EU-supported environmental and digitalization policies. However, data security, system sustainability, and high technology costs in small-scale recreation areas stand out as significant problem areas for Lithuania. This study addresses an underexplored intersection between artificial intelligence applications and environmental governance within recreational tourism contexts, contributing to the emerging literature on digital transformation in sustainable destination management. The findings reveal that AI-supported environmental management systems have significant potential to strengthen sustainable tourism management, increase operational efficiency, and support data-driven sustainable destination strategies. These findings offer practical implications for destination managers and policy makers by highlighting how AI-enabled environmental governance systems can enhance sustainability-oriented decision-making and improve operational efficiency in recreational tourism areas.

Urban renewal increasingly adopts Nature-Based Solutions (NBSs) to address environmental challenges and enhance social well-being. However, it remains unclear whether and to what extent NBSs contribute to cultural ecosystem services (CESs), which reflect people’s perceptions, values, and experiences of urban nature. This study develops an integrated framework combining text and image mining of social media data to evaluate the CES outcomes of NBS in regenerated urban districts in Chengdu, China. The comment data were analyzed for CES using Jieba word segmentation and dictionary matching, while images were categorized into NBS types by manual classification. By integrating these multimodal data, the framework effectively clarifies the relationship between NBSs and CESs from the perspective of public perception. Results indicate that recreation and leisure, inspiration, and spiritual values are the most prominent aspects of public perception, with linear green infrastructure and pocket parks being the most frequently identified NBS types. Correspondence analysis further reveals significant associations between specific NBS interventions and CES categories. By integrating textual and visual data, this study offers a practical and real-time approach for capturing public perceptions of CESs and provides actionable insights for the design and management of NBS-driven urban regeneration.

Kauri dieback, caused by Phytophthora agathidicida Weir, Beever, Pennycook & Bellgard, poses a major threat to the ecological and cultural significance of Aotearoa New Zealand’s kauri forests. Visitor behaviour, particularly boot-cleaning and adherence to track-use guidelines, is a key transmission pathway. Using the COM-B framework and audience segmentation, we surveyed 451 visitors to the Waitākere and Hunua Ranges to identify behavioural drivers, barriers, and segment-specific intervention needs. Stepwise regressions accounted for 52% of the variance in self-reported boot-cleaning compliance and 56% in track-use compliance within this sample (adjusted R²). Boot-cleaning compliance was enhanced by habit strength, worry about spreading the pathogen, awareness of correct procedures, and reliance on functional cleaning stations, while inconvenience and chemical aversion reduced compliance. Track-use compliance was lowered by perceived low likelihood of spread, doubts about mitigation effectiveness, time-cost concerns, and strong forest-use identity, whereas protection motivation and habitual rule-following increased compliance. Latent profile analyses produced three segments per behaviour: boot-cleaning—Conflicted, Receptive, Engaged; and track-use—Identity-Driven Forest Users, Uncommitted, Engaged—which differed systematically in knowledge, concern, and compliance. We outline potential intervention implications informed by these findings and prior literature. Full article

With the development of ecotourism, national park recreation research has evolved from a marginal branch of tourism studies into a vibrant interdisciplinary field. Although scholarly attention has grown, a systematic, holistic overview of its global development trajectory and knowledge structure remains lacking. To address this gap, this study presents a bibliometric analysis of national park recreation research published from 1994 to 2024, based on the Web of Science Core Collection. Using CiteSpace for scientometric visualization, we examine the field’s evolutionary phases, collaboration networks, thematic distributions, and emerging trends. Our results show that national park recreation research has progressed through three distinct stages: initial emergence, steady development, and rapid growth. Collaboration among individual researchers and institutions remains generally limited. Dominant research themes include spatial planning and zoning, ecological conservation, stakeholder engagement, cultural ecosystem services, and tourists’ pro-environmental behaviors. Building on these findings, we synthesize a comprehensive knowledge structure of this field and outline key future research priorities. This overview enables researchers to quickly grasp the field’s global research panorama and identify targeted thematic directions. We call for greater attention to understudied areas, including visitor social psychology, community participation, digital technology applications, and adaptive management in future studies.

Leptospirosis is an emerging zoonotic infectious disease in the adventure traveler with recreational freshwater exposure. We describe three cases of probable leptospirosis acquired during whitewater rafting trips in rural Ecuador. Rafting took place following periods of heavy rainfall and flooding of rivers, which are well documented risk factors for leptospirosis. Two of our patients presented to our rapid assessment clinic with acute febrile illness after travel to a region with a confirmed leptospirosis outbreak, while the third patient presented four weeks after a convalescent episode of acute febrile jaundice during a dramatic rise in reported leptospirosis cases in Ecuador. Delayed turnaround times for confirmatory microbiologic diagnostics in leptospirosis challenge its management and necessitate provisional clinical diagnosis and empiric antimicrobials based on compatible clinical symptoms, biochemical abnormalities, exposure history, and known outbreak epidemiology. We herein situate the presentations of our patients within the broader literature by reviewing the clinical, diagnostic, therapeutic, and prognostic considerations when caring for leptospirosis patients. Leptospirosis should be considered in the differential diagnosis of all patients presenting with acute febrile illness following adventure travel with freshwater exposure, and empiric treatment should be considered given the absence of readily available confirmatory microbiologic testing.

This study evaluates publicness and spatial quality along the Çoruh Riverfront in the city center of Bayburt through the Project for Public Spaces (PPS) framework. The research is based on a literature review, interpretation of satellite imagery, on-site observation, production of visual documentation, and surveys conducted with a total of 210 participants, including 30 users in each of seven public spaces. The findings show that the presence of parks along the riverfront alone does not produce continuous and inclusive public life. In the composite PPS index, July 15 Martyrs Park showed the strongest profile (63.4%), whereas the surroundings of Kıyasi Şentürk Mosque showed the most vulnerable profile (44.1%). The mean values indicate that Access and Linkages are relatively strong (62.5%), whereas Comfort and Image constitute the weakest dimension (46.2%). This result suggests that although the Çoruh Riverfront is physically accessible, it has difficulty producing continuity in terms of staying, shade, orientation, maintenance, safety, and inclusive social programming. The study argues that, in small-scale Anatolian cities, riverfronts should be planned not as fragmented recreational areas but as accessible, socially inclusive, and ecologically sensitive blue-green public spines. Therefore, this study does not use PPS merely as a scoring tool. It uses it as a placemaking framework that makes it possible to read public continuity, place-led management, and social-ecological sustainability together on small-city riverfronts. The findings are interpreted as exploratory and diagnostic evidence for planning and design, rather than as inferential statistical proof of site-level differences or direct ecological performance.

The aims of this study were to determine the geographical range and habitats of the Verbascum species in the Arabian Peninsula and to assess their conservation status at national, regional, and global levels by using the International Union for Conservation of Nature (IUCN) Red List categories and criteria. Verbascum is represented by 16 species with four varieties in the area of the study, and most of these species are endemic to Saudi Arabia, Yemen, Oman, and the United Arab Emirates (UAE). This study is based on an ecogeographic survey, which was conducted using herbaria collections, literature sources, and fieldwork. The findings showed that the genus is distributed in three main regions in the Arabian Peninsula, which include northern Saudi Arabia, the Asir and Yemen highlands, and the Hajar mountains in Oman and the UAE. In addition, most species of Verbascum in the region are at high risk of extinction. Nine taxa are threatened, four of which are assessed as Critically Endangered, four as Endangered, and one as Vulnerable. Furthermore, four species are assessed as Near Threatened, while another five species are assessed as of Least Concern. Threats to the Verbascum species in the region are overgrazing, suburban and agricultural expansion, climate change, invasive species, recreational activities, tourism, war, and civil unrest, leading to human intrusion and disturbances. Some important strategies for conserving and managing Verbascum species on the Arabian Peninsula are recommended here. Full article

Public spaces are important components of urban life, supporting social interaction, recreation, and environmental outcomes. Their success, however, depends not only on their physical provision but also on governance structures that guide their daily operation and maintenance routines. This study examines how operational governance and management practices influence user perception of public spaces by comparing two urban parks in Kathmandu: Ratna Park, a major city-level space, and Nandi Keshwor Bagaicha Park, a neighborhood-scale park. Using a mixed-method approach, the research employed a user survey (n = 191), interviews, and field observations. Survey data were used to develop composite indices for maintenance, safety, amenities, and user comfort. Descriptive statistics, Pearson correlations, independent-samples t-tests, and multiple regression models were used to examine the influence of governance on user perception. The findings reveal notable differences between the two parks. Nandi Keshwor Bagaicha Park scored higher on perceived safety (mean = 4.30) and comfort (mean = 4.01), while Ratna Park showed stronger performance in amenities (mean = 3.91). Although correlations between governance indicators and comfort were weak, regression analyses showed that maintenance, safety, and amenities accounted for only a small portion of the comfort variance (r² = 0.03). These findings indicate that operational variables alone do not fully explain user perception and suggest that broader management practices and patterns of use may also influence perceptions of comfort. This study provides exploratory empirical insight into public space governance and highlights the importance of strengthening operational systems and management practices in contemporary cities.

Diadromous fish provide key ecological and socio-economic services in European Atlantic catchments, yet their marine phase remains poorly understood and weakly integrated into management. Involving nine partners from Portugal, Spain, France and Ireland, the DiadSea Interreg Atlantic Area initiative aims to fill these critical knowledge gaps on the marine and estuarine phases and to translate this information into coordinated conservation and fisheries management tools. To do so, the project combines historical and newly collected fishery-dependent and -independent data (landings, by-catch, cooperative surveys with commercial and recreational fishers) with advanced microchemical, genetic and environmental DNA (eDNA) analyses to characterize marine distributions, mixing areas and connectivity for shads, Atlantic salmon, sea trout, European eel, sea lamprey and other diadromous species. It also includes innovative case studies on lamprey tagging and intestinal metabarcoding, coastal habitat suitability mapping for shads using river plumes and environmental variables, and joint otolith microchemistry–genomics approaches to reassess European eel panmixia and maternal origin at the Atlantic scale. Species distribution models under present and future climate scenarios, specifically RCP4.5 and RCP8.5, are used to identify priority marine areas for conservation, zones of high temporal turnover and key interfaces ensuring longitudinal (river–sea) and latitudinal connectivity, which will feed into an updated interactive web Atlas of diadromous species. In parallel, DiadSea establishes a transnational observatory of stakeholders to harmonize legislation, co-develop adaptive fisheries management plans and produce climate-aware policy guidelines, while capacity-building actions include an origin-labeling scheme for sustainably harvested diadromous fish, educational games and a comic book to raise awareness among younger generations and the wider public. Together, these work packages will deliver the first integrated, marine-focused, evidence-based and decision-support framework for diadromous fishes in the North-Eastern Atlantic, strengthening conservation, sustainable fisheries and stakeholder engagement under ongoing climate change.

Transitional waters—such as estuaries, lagoons, deltas, and coastal wetlands—are dynamic environments where freshwater and seawater interact, forming highly productive and biologically diverse ecosystems. Shaped by temperature and salinity gradients, tidal influence, sediment transport, and nutrient-rich conditions, these habitats support diverse ecological functions. Their structural complexity—including seagrass beds, salt marshes, mudflats, and mangroves—provides essential habitats for many fish species. These areas are crucial for fish life cycles, serving as nurseries, spawning grounds, feeding zones, and refuges from predators. Many commercially important species depend on them during early life stages before moving offshore, making them vital for both commercial and recreational fisheries. Beyond food provision, they deliver key ecosystem services, including water purification, coastal protection, and carbon storage. Research on the fish community of the Ria Formosa lagoon in Portugal since the 1980s highlights long-term changes in the fish community and the dominant role of habitat structure and temporal dynamics. Subtidal seagrass beds support higher fish abundance and diversity than unvegetated areas, acting as key nursery habitats and provide important fish provisioning services. Seasonal variation is also central, driven by recruitment pulses of marine migrants in late winter–spring. Recent pressures on this system have been driven by human activity and environmental change. Seagrass loss reduces nursery and feeding areas, while pollution degrades water quality. Overfishing (including illegal fishing), recreational activities, and aquaculture expansion add stress. Climate warming and invasive species such as Caulerpa prolifera, further disrupt ecosystem balance and threaten biodiversity. Sustainable management—such as habitat restoration, protected areas, and integrated policies—is essential to preserve the ecological and economic value of this unique lagoon. Ongoing research, monitoring, habitat restoration, and stakeholder engagement remain critical for ensuring resilience. Full article

Introduction: Marine recreational fishing (MRF) is a socially, economically, and ecologically important activity. However, the absence of systematic monitoring and research in Portugal has limited a comprehensive understanding of the sector and its broader implications. Addressing these gaps is essential to support evidence-based and adaptive recreational fisheries management. Objective: This work aimed to improve understanding of marine recreational fishing in Portugal by integrating social and biological perspectives across national, regional, and local scales. Methodology: A multidisciplinary approach was applied. At the national scale, online questionnaire data were combined with licencing information and regional effort estimates to quantify fishing effort, catches, release rates, catch composition, and direct trip expenditures. The same survey framework was also used to identify recreational fisher profiles based on motivations, behaviours, fishing practices, and attitudes toward management. At the local scale, shore angling surveys conducted before the implementation of the Natural Marine Park of the Algarve Reef were used to estimate fishing activity and establish a baseline for future monitoring. From a biological perspective, field-based catch-and-release experiments were conducted to assess post-release mortality and physiological disturbance, using indicators such as mortality, condition, capture and handling variables, and blood biomarkers of stress and recovery. Results: The national estimates documented substantial fishing effort, catches, and direct expenditure, confirming the relevance of MRF in Portugal at both ecological and socio-economic levels. Portuguese recreational fishers were also shown to be heterogeneous in their motivations, behaviours, and practices, reinforcing the need for management approaches that reflect this diversity. At the local scale, shore angling estimates from the Natural Marine Park of the Algarve Reef provided an important pre-protection baseline for the now established Marine Protected Area, enabling future comparisons and long-term assessment of management effects. Biological experiments showed that recreational fishing can generate measurable physiological disturbance in fish, with post-release condition influenced by capture and handling factors. Among the variables examined, hook location emerged as particularly important, with deep-hooked fish showing greater impairment and higher mortality risk. Conclusions: Together, these findings show that improving recreational fisheries management in Portugal requires integrating social patterns, fishery magnitude, and biological responses to capture and release. Long-term monitoring programmes, combined with management approaches adapted to different fisher profiles and fishing contexts, are essential to support more effective and sustainable recreational fisheries governance.

Introduction: Freshwater fish communities in Mediterranean basins have undergone profound changes over recent decades due to biological invasions, habitat alteration, and hydrological regulation. The Segura River basin (SE Spain), particularly in the Region of Murcia, represents a paradigmatic case of these transformations, with increasing pressures on native ichthyofauna and growing relevance for recreational fisheries. Objective: This study aims to provide an updated inventory of fish communities in the rivers and reservoirs of the Region of Murcia, assessing current composition, relative abundance, and conservation status. Methodology: Fish assemblages were surveyed during sampling campaigns conducted in autumn 2023, 2024 and 2025. Sampling sites included representative reservoirs and river reaches within the middle sector of the Segura River basin, focusing on areas of interest for recreational fishing. Passive fishing gears were used in reservoirs, while electrofishing was conducted in riverine habitats. Presence and relative abundance data were recorded for all detected taxa. Results: A total of 15 taxa were identified (8 in reservoirs and 15 in river reaches). Reservoir communities were almost entirely dominated by non-native invasive species, including Cyprinus carpio, Alburnus alburnus, Sander lucioperca, Micropterus salmoides, Lepomis gibbosus, and Gambusia holbrooki, with Luciobarbus sclateri as the only native species. Riverine sections of the main channel also showed a strong dominance of exotic taxa, with additional species such as Esox lucius, Oncorhynchus mykiss, Gobio lozanoi, and Pseudochondrostoma polylepis. Native species detected included L. sclateri (dominant), Anguilla anguilla, and Salariopsis fluviatilis, the latter showing a recent expansion likely linked to human-mediated introduction. Isolated tributaries hosted the most valuable assemblages, including populations of L. sclateri, Squalius tartessicus, and the endangered Valencia hispanica (recently unauthorized translocations into the Segura river basin). Conclusions: Current fish communities in the Region of Murcia reflect a marked ecological degradation compared to historical conditions, driven by the proliferation of non-native species and habitat alteration. Changes over the last 30 years have been particularly pronounced in reservoirs and regulated sections of the main river channel, where local extinction of the native S. tartessicus has also been detected. Only the headwaters of certain tributaries retain fish assemblages of notable conservation interest, highlighting their priority for management and protection. Full article
