This bias spells multi-arrayed challenges for carnivores living in anthropized landscapes. The globally Vulnerable fishing cats (<em>Prionailurus viverrinus</em>) living across human-dominated South Asian wetlands exemplify this problem. Bangladesh, a densely populated, tenuous place for human-wildlife coexistence, constitutes ∼ 30 % of the fishing cat’s known distribution range. Based on systematic surveys of media reports (n = 361; 2005–2021), we implemented a novel application of predictive modeling to map fishing cat presence, and hotspots of human–fishing cat negative interactions across Bangladesh. The distribution of fishing cats was best explained by the extent of wetlands and dry-season precipitation. Negative interactions were associated with patchy mosaics of wetlands, croplands, and road networks. Around 47 % of the reported negative interactions were triggered by mere sightings of the cat and 26 % involved transactional costs. Chase-and-capture of the ‘problem’ animal ensued in &gt; 50 % of reported cases; 26 % mentioned the use of traps or other gears. From 31 % of reports, we recorded 160 fishing cat mortality incidents, but no human fatalities. Our results show that around one-third of Bangladesh likely has breeding fishing cat populations; &gt; 95 % of these regions are outside Protected Areas. We recommend formulating an action plan to strategize a redressal policy, enhance public perception of coexistence, and increase conservation units. We suggest applying this case study to other fishing cat range countries, or other carnivores in the Global South, where data deficiency and lack of systematic large-scale assessments often hinder conservation interventions.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"59 ","pages":"Article e03505"},"PeriodicalIF":3.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Our findings suggest that plant availability is a major predictor of the sheep's range. The species distribution models (SDMs) incorporating biotic interactions, i.e., plant availability, increases accuracy in predicting the underlying implications of climate change on ungulates compared to models that exclude these interactions. Our results reveal discrepancies in ungulate spatial distribution patterns, with future suitable habitat contraction being less pronounced when incorporating biotic variables than without biotic variables (27 % vs. 33 %). Therefore, ignoring biotic interaction may overestimate the impacts of climate change, resulting in the inefficient allocation of scarce conservation resources. Additionally, our results indicate the importance of protected areas (PAs) as important climatic refugia, though less than half of the range is currently within PAs.

Overall, TNC provides a more coherent explanation for our results in the Chilean Andes than OTT. Lower SR and lack of phylogenetic clustering at lower elevations on the two gradients are attributed to contingencies of the Miocene uplift of the Andes leading to a more arid climate and depressed treeline.

Through cubic polynomial fitting, we analyzed the responses of these ESs to climate change and fractional vegetation cover (FVC), identifying critical threshold points. Between 2000 and 2020, the TRB experienced slight increases in temperature (+0.028°C per decade) and precipitation (+2.9 mm per decade), while FVC showed significant spatial heterogeneity, with notable declines in the northern mountainous areas. Specific thresholds for ESs were identified: 1.57°C for temperature, 60.3 mm for precipitation, and 16 % for FVC. Exceeding these thresholds triggered varying degrees of functional changes in ESs. Identifying these thresholds is essential for assessing the vulnerability of ESs and improving our understanding of the complex relationships between ESs and environmental changes in the arid area.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"59 ","pages":"Article e03529"},"PeriodicalIF":3.5,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143579431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
