Introduction Terrestrial mammals play a pivotal role in tropical forest ecosystems, representing rich and functionally diverse component of these biomes. However, they confront formidable threats globally, such as hunting, habitat loss, fragmentation, amidst the expansion human-altered landscapes regions. Understanding impacts changes on mammal communities is crucial for designing effective conservation interventions. Northeast India's forests, biodiversity hotspot, host array mammalian fauna. The primary challenge faced by species involves anthropogenic activities leading to shrinkage fragmentation forested habitats. Methodology In this study, we conducted systematic camera trapping Mehao Wildlife Sanctuary (WLS) assess status distribution. Employing single-season occupancy models, evaluated factors influencing species' detection probability spatial utilization within landscape. Results study documented 27 species, with 12 identified "threatened" IUCN Red List. Species like clouded leopard, marbled cat, Gongshan muntjac, red goral, Mishmi takin, sambar were recorded but observed infrequently. Notably, reported Asiatic brush-tailed porcupine's first sighting Mehao. Our findings revealed that undisturbed habitats preferred all species. Mainland serow dominated most sanctuary's area, followed northern yellow-throated marten, masked palm civet. Discussion response ecological covariates varied significantly, underscoring necessity species-specific management strategies alongside landscape-scale approach. These outcomes emphasize urgency managing safeguarding rare elusive around WLS.

Precipitation changes modify C, N, and P cycles, which regulate the functions structure of terrestrial ecosystems. Although altered precipitation affects above- belowground C:N:P stoichiometry, considerable uncertainties remain regarding plant-microbial nutrient allocation strategies under increased (IPPT) decreased (DPPT) precipitation.

Abstract Forestation efforts are accelerating across the globe in fight against global climate change, order to restore biodiversity, and improve local livelihoods. Yet, so far non‐local effects of forestation on rainfall have largely remained a blind spot. Here we build upon emerging work propose that targeted enhancement may also be considered prioritization forestation. We show tools achieve this rapidly becoming available, but identify drawbacks discuss which further developments still needed realize robust assessments face change. programs then mitigate not only change itself its adverse form drying.

Using historic time series river levels 90 gauges, we look how long lasted regions impacts. Results indicate 2005, 2010, and 2016 were most severe, over an additional month low water those years. Such drought events routinely disrupt inland transport isolate local populations, limiting access essential goods (food, fuel, medicine) basic services (healthcare, education). Given this new reality, countries must develop long-term strategies for mitigation, adaptation, disaster response.
