We evaluated whether high-resolution digital surface models (DSMs) (≤1 m) based on data from an unmanned aerial vehicle (UAV) enhanced species distribution models (SDMs) relative to medium‑resolution satellite-based ALOS World 3D (AW3D) DSMs (≥30 m) for François' langur (Trachypithecus francoisi). This endangered primate represents an ideal focal species for evaluating SDM performance because its habitat consists of topographically complex karst mountains. Using a systematic comparative framework, we built 290 random forest SDMs across multiple spatial resolutions (3-150 m) and sample sizes (30-122 occurrence records). We assessed model accuracy with the area under the receiver operating characteristic curve (AUC-ROC) and the area under the precision-recall curve (AUC-PR). The UAV DSM improved model performance across all metrics, particularly identification of microhabitat. Performance improvements were scale dependent and most pronounced at fine spatial resolutions of 3-10 m. Improvement was less at coarser resolutions above 100 m, where topographic aggregation reduced fine-feature discrimination. The UAV-based models were more accurate than AW3D-based models even with fewer presence records, indicating greater robustness in data-limited mountainous surveys. Slope-related predictors derived from UAV DSM were more important than those derived from AW3D DSM, suggesting that high-resolution elevation data more effectively resolve terrain features relevant to species habitat selection. The UAV DSM showed wildlife corridors in steep terrain that did not appear in the AW3D DSM.

The importance of such collaborations has spurred calls by Western and Indigenous researchers to engage in equitable coproduction of ecological research that integrates multiple ways of knowing. However, Indigenous-led conservation research is exceedingly rare. We conducted a case study, applicable globally, in which an Indigenous community experiencing intense industrial resource extraction used Indigenous knowledge and Western science to examine the impacts on species highly valued by the community, namely, furbearing mesocarnivores. Unique knowledge offered by elders and the community suggested rapid declines in many formerly abundant species. Together, we used camera trapping and statistical modeling to investigate the relative abundance of and response to disturbance in lynx (Lynx canadensis), red fox (Vulpes vulpes), marten (Martes americana), and fisher (Pekania pennanti) in north-central Alberta. Low species abundance presented analytical challenges, necessitating pooling species. Several industrial features were associated with (small) increased relative abundance of furbearers (β range 0.12 to 0.30), whereas several others were associated with negative abundance of furbearers (β range -0.25 to -0.64). As Indigenous communities globally face such industrial pressures, we illustrate how Indigenous-led research design, hypotheses, data collection, and interpretation, coupled with statistical ecological data analysis, can inform pressing conservation decisions. Indigenous Peoples face ongoing challenges accessing essential traditional resources because declining ecosystem functioning is directly linked to Indigenous well-being.

We engaged a group of species experts in a decision-analytic process to elicit uncertainties, framed as alternative hypotheses, about current population declines of the American kestrel (Falco sparverius) in the United States. Participants scored 13 hypotheses across 3 CVoI criteria, which are defined as constructed scales. Rather than experts selecting a single score per criterion, we used a likelihood point method to incorporate parametric uncertainty in the scoring process, in which experts were given 100 points to distribute across possible score categories within the criterion-specific constructed scale. Experts provided scores over 2 scoring rounds, with an opportunity to review and discuss initial scores between rounds. We used a Shannon entropy calculation to quantify how evenly participants allotted their points. We used simulation to evaluate the robustness of our prioritization results relative to a scoring method in which participants selected a single score category for each criterion. Participants often spread their points across 2 adjacent scores, reflecting parametric uncertainty. For one third of the hypothesis-scoring round combinations, the prioritization results differed in approximately 50% of simulations. The highest scoring hypotheses related to how the use of artificial versus natural nest cavities affects fecundity or survival, whether winter roosting sites are a limiting factor for population growth, and whether gamebird habitat management may benefit kestrel populations.

The annual movement of millions of shipping cargo containers, of which few are inspected due to resource constraints, facilitates the smuggling of large quantities of wildlife contraband. Rapid, noninvasive screening tools are essential for border control agencies to effectively detect and intercept wildlife trafficking attempts, though such tools are currently limited. Detection dog programs could be highly effective in this context; however, their capacity to screen large volumes of cargo without disrupting port operations remains a challenge. We explored the feasibility of pairing an air extraction device, which samples air from sealed containers, with canine detection to improve screening measures. To evaluate this method, we used pelts from adult specimens of the African lion (Panthera leo), cheetah (Acinonyx jubatus), leopard (Panthera pardus), snow leopard (Panthera uncia), and tiger (Panthera tigris) concealed in containers to simulate smuggling scenarios. On average across the container configurations trialed, the detection dog achieved high diagnostic sensitivity (97.6%, 95% CI 95.1-100.0) and specificity (84.8%, 95% CI 79.1-90.6). Detection accuracy was not significantly influenced by airflow conditions (extraction only vs. mixed-mode ventilation) or pelt arrangement within the containers. These findings highlight the potential of this approach in enhancing the detection of concealed wildlife products. However, the air extraction protocol must be validated under real-world operational conditions to confirm its practicability. Through the integration of extraction-based air sampling into existing screening frameworks, this approach could offer a scalable, noninvasive strategy to strengthen wildlife trafficking detection.</p>","PeriodicalId":10689,"journal":{"name":"Conservation Biology","volume":" ","pages":"e70225"},"PeriodicalIF":5.2,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13392749/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146092291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We rasterized species ranges, then counted the range edges of each species in each grid cell. This approach enables high-resolution mapping across regions and facilitates the integration of β diversity into conservation planning. We applied this approach to the Eastern Himalayas, where 3 biodiversity hotspots abut, and used endemic bird species as our focal taxa. Our analyses revealed differences between areas of high species richness and high species turnover. Areas of high species richness were concentrated in montane forests, whereas areas of high species turnover tended to be low in mountain forests and peak in foothills and tree lines. Both areas of high species richness and high species turnover are inadequately protected. We contend that species turnover is a critical, complementary metric to species richness in understanding patterns of biodiversity. In addition, areas of high species turnover host unique species assemblages and face a dual challenge. They host peripheral populations that are more prone to local extinction, and communities within them are particularly sensitive to climate change. These vulnerabilities heighten the urgency of protecting such areas.

EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs. However, like wild populations, populations in EEPs are at risk of genomic erosion, undermining population viability. Current population management is based on studbook and pedigree records, and this information is used to maintain genetic diversity and prevent inbreeding. We examined how genomics-informed conservation management can improve current practices. Using computer simulations, we identified EEP species' characteristics that make them more prone to genomic erosion. EEP species with large ancestral population sizes and low fecundity (i.e., K-strategists) were most at risk of a genetic load of harmful mutations and inbreeding depression. Founder population size is critical for EEP species with large ancestral population sizes and high fecundity (r-strategists), especially if the initial population growth rate is slow. Large breeding population size and effective population size were beneficial for viability for all EEP species. We showed that inbreeding depression peaked at approximately 10 generations after founding and that fitness never completely recovered in EEP species compared with in wild ancestors. Due to a time lag (drift debt), genomic erosion did not become apparent until after ∼3 generations, which implied that biobanking (the long-term storage of biological samples) would be best conducted within this initial period. Thus, genomics data can be used to better maintain genetic diversity, reduce genetic load, and minimize inbreeding depression in EEPs. Genomics data can also identify inadvertent hybridization, which threatens ex situ programs managing closely related species or evolutionary significant units together.
