This study explores the use of chlorography as a natural photographic developing technique that utilizes the decomposition of chlorophyll and other plant pigments through the action of sunlight. The developed images corresponded to previous research on changes in the iconography of the indigenous Salasaka people. In this context, this experimental project on natural photography is oriented toward the conservation of the ancestral knowledge of this community and the understanding of the native flora of Ecuador. We investigated the application of the contact image transfer technique with positive transparencies on leaves and flowers of 30 different species that grow in the Ecuadorian highlands, including leaves of vascular plants, as well as rose petals. The results showed that the clarity and contrast of chlorography depended on the plant species and exposure time. It was observed that fruit-bearing species produced more visible images than the leaves of other plants and rose petals, with species from the Passifloraceae family proving particularly effective. We interpreted these findings within the framework of plant photophysical mechanisms, proposing an inverse relationship between development efficiency and species’ non-photochemical quenching (NPQ) capacity. Furthermore, we interpreted the findings in relation to the photobleaching of pigments and compared chlorography with other natural photographic processes such as anthotypes. Key factors influencing the process were identified, such as the type of leaf, the intensity and duration of light, and the hydration of the plant material. It is concluded that chlorography is a viable, non-toxic, and environmentally friendly photographic alternative with potential applications in art, education, and research, although it presents challenges in terms of image permanence and reproducibility.

Human-Wildlife conflict (HWC) presents a growing challenge for wildlife conservation, especially as species recover and reoccupy human-dominated landscapes, creating tensions between ecological goals and local livelihoods. Such conflicts are increasingly reported across Europe, including Romania, involving semi-aquatic species like the Eurasian beaver (Castor fiber L.) and Eurasian otter (Lutra lutra L.). Enhancing coexistence with wildlife through the integration of conflict mapping, stakeholder engagement, and spatial analysis into conservation planning is therefore essential for ensuring the long-term protection of conflict species. A mixed-methods approach was used, including structured surveys among stakeholders, standardized damage report collection from institutions, and expert field assessments of species activity. The results indicate that while most respondents recognize the legal protection of both species, a minority have experienced direct conflict, primarily with beavers through flooding and crop damage. Tolerance varied markedly among demographic groups: researchers and environmental agency staff were most accepting, whereas farmers and fish farm owners were the least accepting; respondents with no personal damage experience and those with university or post-secondary education also displayed significantly higher acceptance toward both species. Institutional reports confirmed multiple beaver-related damage sites, and through field validation, conflict forecast zones with spatial clustering in Harghita, Brașov, Covasna, and Sibiu counties were developed. These findings underscore the importance of conflict forecasting maps, understanding the coexistence dynamics and drivers of acceptance, and the need to maintain high acceptance levels toward the studied species. The developed maps can serve as a basis for targeted interventions, helping to balance ecological benefits with socioeconomic concerns. Full article

This research advances the integration of terrestrial laser scanning (TLS) in heritage documentation, targeting the development of holistic and practical guidance for practitioners to adopt the technology effectively. Acknowledging the pivotal role of TLS in capturing detailed and accurate representations of cultural heritage, the study emerges against a backdrop of technological progression and the evolving needs of heritage conservation. Through a comprehensive literature review, critical case studies of heritage sites in the U.S., expert interviews, and the development of a TLS for Heritage Documentation Best Practice Guide (the guide), the paper addresses the existing gaps in streamlined practices in the domain of TLS’s applications in heritage documentation. While recognizing and building upon foundational efforts such as international guidelines developed over the past decades, this study contributes a practice-oriented perspective grounded in field experience and case-based analysis. The developed guide seeks to equip practitioners with structured methods and practical tools to optimize the use of TLS, ultimately enhancing the quality and accessibility of heritage documentation. It also sets a foundation for integrating TLS datasets with other technologies, such as Building Information Modeling (BIM), virtual reality (VR), and augmented reality (AR) for heritage preservation, tourism, education, and interpretation, ultimately enhancing access to and engagement with cultural heritage sites. The paper also critically situates this guidance within the evolving theoretical discourse on digital heritage practices, highlighting its alignment with and divergence from existing methodologies.

The intersection of religion and education in the United States dates to colonial times, as do attempts by religious institutions and individuals to regulate educational content. After a prominent retreat by religious fundamentalists following the Scopes Monkey Trial, conservative Christians have once again entered political debates about educational content in the form of modern culture wars issues. Both conservatives and liberals have attempted to punish educators for political comments made in class, but the influence of religion on individual attitudes has yet to be examined. In this article, we use an original survey experiment to examine individuals’ propensity to punish a professor who makes politically charged comments in class. We also assess whether religious individuals are more likely to punish professors for comments disparaging conservatives or liberals. We find that high-attending religious individuals, including both Evangelicals and Catholics, are more likely to support punishing the professor. However, we find that the propensity to punish is not related to the target of the professor’s comments. These findings suggest a resurgence of religious interest in education as a cultural issue at the individual, and not just institutional, level and a coalition between Evangelicals and Catholics on this issue.

Artificial intelligence technologies, particularly machine learning and computer vision, are being increasingly utilized to preserve, restore, and create immersive virtual experiences with cultural artifacts and sites, thus aiding in conserving cultural heritage and making it accessible to a global audience. This paper examines the performance of Generative Adversarial Networks (GAN), especially Style-Based Generator Architecture (StyleGAN), as a deep learning approach for producing realistic images of Egyptian monuments. We used Sigmoid loss for Language–Image Pre-training (SigLIP) as a unique image–text alignment system to guide monument generation through semantic elements. We also studied truncation methods to regulate the generated image noise and identify the most effective parameter settings based on architectural representation versus diverse output creation. An improved discriminator design that combined noise addition with squeeze-and-excitation blocks and a modified MinibatchStdLayer produced 27.5% better Fréchet Inception Distance performance than the original discriminator models. Moreover, differential evolution for latent-space optimization reduced alignment mistakes during specific monument construction tasks by about 15%. We checked a wide range of truncation values from 0.1 to 1.0 and found that somewhere between 0.4 and 0.7 was the best range because it allowed for good accuracy while retaining many different architectural elements. Our findings indicate that specific model optimization strategies produce superior outcomes by creating better-quality and historically correct representations of diverse Egyptian monuments. Thus, the developed technology may be instrumental in generating educational and archaeological visualization assets while adding virtual tourism capabilities. Full article

Based on a comprehensive review of the current research status of ecological compensation both domestically and internationally, combined with field survey data, this study delves into the issue of multi-stakeholder participation in the ecological compensation mechanisms of the Xin’an River Basin. This research reveals that the joint participation of multiple stakeholders is crucial to achieving the goals of ecological compensation in river basins. The government plays a significant role in macro-guidance, financial support, policy guarantees, supervision, and management. It promotes the comprehensive implementation of ecological environmental protection by formulating relevant laws and regulations, guiding the public to participate in ecological conservation, and supervising and punishing pollution behaviors. The public, serving as the main force, forms strong awareness and behavioral habits of ecological protection through active participation in environmental protection, monitoring, and feedback. As participants, enterprises contribute to industrial transformation and green development by improving resource utilization efficiency, reducing pollution emissions, promoting green industries, and participating in ecological restoration projects. Scientific research institutions, as technology enablers, have effectively enhanced governance efficiency through technological research and innovation, ecosystem value accounting to provide decision-making support, and public education. Social organizations, as facilitators, have injected vitality and innovation into watershed governance by extensively mobilizing social forces and building multi-party collaboration platforms. Communities, as supporters, have transformed ecological value into economic benefits by developing characteristic industries such as eco-agriculture and eco-tourism. Based on the above findings, further recommendations are proposed to mobilize the enthusiasm of upstream communities and encourage their participation in ecological compensation, promote the market-oriented operation of ecological compensation mechanisms, strengthen cross-regional cooperation to establish joint mechanisms, enhance supervision and evaluation, and establish a sound benefit-sharing mechanism. These recommendations provide theoretical support and practical references for ecological compensation worldwide. Full article

This paper investigates how governance frameworks shape sustainable tourism outcomes in protected areas by comparing Tara National Park (Serbia) and Triglav National Park (Slovenia). Both parks, established in 1981 and classified under IUCN Category II, exhibit rich biodiversity and mountainous terrain but differ markedly in governance structures, institutional integration, and local community engagement. Using a qualitative, indicator-based methodology, this research evaluates ecological, economic, and social dimensions of sustainability. The findings reveal that Triglav NP demonstrates higher levels of participatory governance, tourism integration, and educational outreach, while Tara NP maintains stricter ecological protection with less inclusive management. Triglav’s zoning model, community council, and economic alignment with regional development policies contribute to stronger sustainability outcomes. Conversely, Tara NP’s centralized governance and infrastructural gaps constrain its potential despite its significant conservation value. This study highlights the importance of adaptive, inclusive governance in achieving the Sustainable Development Goals (SDGs) within protected areas. It concludes that hybrid approaches, combining legal rigor with participatory flexibility, can foster resilience and sustainability in ecologically sensitive regions. Full article

This paper presents a conceptual and methodological framework for using Geographical Information Systems (GIS) to “deep map” cultural heritage sites along Ireland’s Wild Atlantic Way, with a focus on the 1588 Spanish Armada wrecks in County Kerry and archaeological landscapes in County Sligo’s “Yeats Country.” Drawing on interdisciplinary dialogues from the humanities, social sciences, and geospatial sciences, it illustrates how digital spatial technologies can excavate, preserve, and sustain intangible cultural knowledge embedded within such palimpsestic landscapes. Using MAXQDA 24 software to mine and code historical, literary, folkloric, and environmental texts, the study constructed bespoke GIS attribute tables and visualizations integrated with elevation models and open-source archaeological data. The result is a richly layered cartographic method that reveals the spectral and affective dimensions of heritage landscapes through climate, memory, literature, and spatial storytelling. By engaging with “deep mapping” and theories such as “Spectral Geography,” the research offers new avenues for sustainable heritage conservation, cultural tourism, and public education that are sensitive to both ecological and cultural resilience in the West of Ireland.

The Gahai wetland in Gansu, China, is a key wetland for nationally and globally threatened bird species. This research aims to quantify the economic value of wetland birds by the method of contingent valuation questionnaire, thereby providing a foundation for conservation of avian species. The result indicated that residents were willing to pay between 208 and 230 CNY (29–32 USD $) annually for bird protection, a total annual value of wetland birds in Luqu County ranging from 7.9 M to 8.8 M CNY (1.1–1.3 M USD $). Men, locals, and older individuals were more inclined to contribute and offered higher payments, albeit non-significant correlation between education level and annual income with the willingness to pay. While the depth of understanding of wetland pressures did not significantly influence the willingness to pay, it did show a positive correlation; those with more profound understanding tended to be more generous in their payments. Tibetan male residents were more likely to prioritize ecological and environmental protection due to their religious beliefs and cultural customs, which emphasize the reverence for and compassion towards birds. This research not only complemented and validated the applicability of the contingent valuation method in China but also underscores the considerations that should be taken into account when employing this method.

Botanical gardens serve as vital centers for ex situ conservation, maintaining diverse plant species under controlled conditions. Terrestrial orchids, despite their wide diversity and distribution, often occur in small and declining populations, making their conservation increasingly urgent. This study aimed to examine the potential for establishing the first specialized orchidarium in Serbia, focusing on the native orchid species of the Fruška Gora region. A SWOT analysis, combined with site assessment data, was employed to identify key strengths, weaknesses, opportunities, and threats, informing the development of a functional zoning plan. The results indicate that such an orchidarium would offer a threefold benefit: strengthening ex situ conservation, advancing scientific research and environmental education, and promoting sustainable tourism. The proposed design consists of eight distinct zones, three of which reflect natural habitats of selected orchid species. The planned integration of a seed gene bank in the central zone, along with living plant collections and a nearby in vitro culture laboratory, establishes a comprehensive framework for the sustainable management of orchid genetic resources in the region, forming a foundation for future research and preservation.

The rising popularity of ecotourism on the Tibetan Plateau has intensified the tension between wildlife conservation and economic development. Conventional wildlife displays often fail to achieve high-fidelity, non-invasive representations of animal morphology and typically lack immersive, interactive features, limiting public engagement in ecological protection. To address these limitations, this study presents a fur simulation algorithm based on the Texture Procedural Overlay Technique (TPOT), integrated with Augmented Reality (AR) technology, focusing on the endangered white-lipped deer in the Sanjiangyuan region. The proposed TPOT-based algorithm enhances the visual realism of fur through multi-layered procedural texturing and physical property fusion. Combined with an AR-driven interactive framework, it seamlessly integrates high-resolution 3D models into real-world environments, significantly improving user immersion and engagement. Comparative experiments demonstrate that the approach surpasses traditional static display fidelity and animation rendering efficiency methods. User feedback further validates its effectiveness for scientific research and environmental education. This work introduces an innovative technological solution for wildlife conservation on the Tibetan Plateau and provides a practical reference for applying digital technologies in ecotourism.

The use of AI-generated content in education is significantly increasing, but its reliability for teaching natural sciences and, more specifically, biodiversity-related contents still remains understudied. The need to address this question is substantial, considering the relevance that biodiversity conservation has on human sustainability, and the recurrent presence of these topics in the educational curriculum, at least in Spain. The present article tests the existence of biases in some of the most widely used AI tools (ChatGPT-4.5, DeepSeek-V3, Gemini) when asked a relevant and objective research question related to biodiversity. The results revealed both taxonomic and geographic biases in all the lists of endangered species provided by these tools when compared to IUCN Red List data. These imbalances may contribute to the perpetuation of plant blindness, zoocentrism, and Western centrism in classrooms, especially at levels where educators lack specialized training. In summary, the present study highlights the potential harmful impact that AI’s cultural and social biases may have on biodiversity education and Sustainable Development Goals-aligned learning and appeals to an urgent need for model refinement (using scientific datasets) and teacher AI literacy to mitigate misinformation.

Tinos Island, part of the Cyclades Complex in the central Aegean Sea, represents a distinctive case of geocultural heritage where geological formations and cultural identity intersect. This study evaluates the geoeducational and geotouristic potential of Tinos’ geosites using GEOAM methodology, which assesses their scientific, educational, and conservation value. Six geosites are examined to explore their geoeducational potential, including prominent locations such as the Tafoni formations and the Exombourgo granite massif. The findings highlight the significance of these sites, while also identifying challenges related to infrastructure, stakeholder engagement, and sustainable management. By integrating geoethics into geotourism practices, Tinos can adopt a balanced approach that enhances environmental conservation alongside community-driven economic benefits. The study underscores the need for collaborative initiatives to optimize the island’s geoheritage for education and tourism, ensuring its long-term preservation. Geotourism, when responsibly implemented, has the potential to strengthen local identity while advancing sustainable tourism development. Full article

Panton–Valentine leukocidin (PVL) is a pore-forming toxin secreted by Staphylococcus aureus (S. aureus) and a significant virulence factor that plays a crucial role in the pathogenesis of dairy mastitis. Previous studies by our research group demonstrated that baicalin inhibits the apoptosis and hyperphosphorylation of cytoskeletal proteins induced by recombinant Panton–Valentine leukocidin (rPVL) in bovine mammary epithelial cells (BMECs). However, the effects of baicalin on the proliferation of BMECs and the underlying mechanism remain unclear. Consequently, this study aimed to explore this underlying mechanism through an LC-MS/MS analysis performed in 4D data-independent acquisition (DIA) mode. Quantitative analysis identified 757 differentially expressed phosphoproteins, among which phosphorylation levels of proteins involved in BMEC proliferation and cell cycle regulation exhibited significant alterations (p < 0.05). rPVL inhibited BMEC proliferation in a dose-dependent manner and induced G0/G1 phase arrest and dephosphorylation of the cell-cycle-related proteins BCLAF1^S285, CDK7^T170, NF2^S518, and PKM2S37. Preintervention with baicalin significantly upregulated the expression and phosphorylation of these proteins and alleviated the G0/G1 phase arrest induced by rPVL in BMECs in vitro. The establishment of the mitotic state in BMECs due to the effect of baicalin appears to be closely related to the regulation of the phosphorylation of CDK7, PKM2, BCLAF1, and NF2. Moreover, in vivo analysis revealed that S. aureus ATCC49775 and rPVL induced dramatic structural destruction and pathological impairment of mammary gland tissues in mice and that these histopathological changes were ameliorated after baicalin intervention. Quantitative immunohistochemical analysis revealed that baicalin mitigated the rPVL-induced dephosphorylation of the aforementioned cell-cycle-related proteins and increased their phosphorylation. Both in vitro and in vivo experimental evidence demonstrated that baicalin effectively reversed rPVL-induced G0/G1 phase arrest in BMECs (p < 0.01) by significantly increasing the phosphorylation levels of cell cycle regulatory proteins (p < 0.05). Additionally, baicalin alleviates pathological damage to mammary gland tissues in mouse models. These data suggest that baicalin possesses antibacterial and antitoxin effects, indicating that it is an effective preventive agent against bovine mastitis. Full article
