ABSTRACT Human‐induced habitat loss and fragmentation threaten biodiversity in the Eastern Himalayas, a crucial part of Indo‐Myanmar hotspot. This study examines distribution 10 mammal species Arunachal Pradesh using multi‐scale ensemble modeling approach, integrating Generalized Linear Models (GLM), Additive (GAM), MaxEnt to assess suitability. By analyzing 57 environmental predictor variables across multiple spatial scales, we found that elevation is key determinant for carnivores such as dhole Asiatic golden cat, while herbivores like northern red muntjac mainland serow prefer broadleaf forests. Species distributions showed distinct patterns, with most concentrated south, except widely distributed yellow‐throated marten. Dhole leopard cat preferred elevated forests, favored mixed Herbivores were at higher elevations, whereas Indian wild pig grasslands degraded habitats near human settlements. While protected areas (PAs) exhibited richness, significant suitable also exist outside these regions, underscoring need landscape‐level conservation strategies. Precipitation seasonality population density emerged predictors, highlighting influence climatic anthropogenic factors on Our findings emphasize necessity conserving large, connected landscapes mitigate human‐induced pressures climate change impacts species. combining ecological insights, this provides framework prioritizing efforts. Future research should expand data collection broader temporal geographic scales incorporate projections anticipate shifts. These are critical guiding effective planning management ecologically rich yet vulnerable region.

Mammal Diversity on Conservation Islands in Protected Areas in Oaxaca, Mexico

Diversity, Journal Year: 2025, Volume and Issue: 17(1), P. 55 - 55

Published: Jan. 16, 2025

Protected sites managed by indigenous people have been used for decades to conserve natural resources. These can be considered “conservation islands” and maintain high biodiversity. This study explores the diversity structure of medium large mammals in (1) four protected areas Oaxaca, Mexico, (2) two different conservation strategies: one area (PNA) three Voluntary Conservation Areas (VCAs). Data from 30 camera traps installed community monitoring between 2013 2019 were used. A total 29,304 days accumulated Central Valleys Western Mountains province. 60,725 photographic records analyzed, resulting 13,471 independent events. Twenty-four species wild documented, including endangered species. VCA showed higher richness compared PNA. Odocoileus virginianus was most dominant PNA, while Dicotyles angulatus VCA. We found differences strategies. Both strategies are effective maintaining mammal richness. consider that these serve as islands that, turn, inter-connect landscapes potential biological corridors.
