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.

Abstract The physical hydroclimate system of the Amazon functions on several spatial and temporal scales. Large-scale processes control main seasonal patterns atmospheric circulation rainfall. Seasonal variability in solar forcing, associated with low rainforest albedo, provides energy for continental heating, convection, onset South American monsoon. Mesoscale cause localized circulations such as river breeze deforestation breeze. We assessed impact different scenarios mid-century last decade rainy season. Here we describe a yet unreported synoptic-scale that delays season southern Amazonia. This model-predicted is driven by extensive (ca. 40%) may long two months. persistent anomalous result delay 30–40 d compared to historical period. Like other phenomena, differences surface heating drive this circulation. Given unabated trends, consequences local ecosystems, agriculture, power generation delayed be difficult revert.

Abstract. The interaction between forest and climate exhibits regional differences due to a variety of biophysical mechanisms. Observational modeling studies have investigated the impacts forested non-forested areas on single variable, but influences cover change combination temperature precipitation (e.g., drought) not been explored, owing complex relationship drought conditions forests. In this study, we use historical datasets explore fraction from 1992–2018. A set linear models an analysis variance approach are utilized investigate effect change, droughts across different timescales zones. Our findings reveal that is dominant factor (among three factors) leading in equatorial, temperate snow regions, while controls arid region. impact changes varies under quantiles. Precipitation modulates cover's long-term region, both short- region as well only Forest can also modulate drought. High leads combined low conditions. contrast, triggers strong improve understanding land system further assist decision-makers management strategies regions light mitigation adaptation.

Abstract Recent satellite and in-situ measurements show that forests can influence regional global cloud cover through biophysical processes. However, forest’s possible local non-local impacts on clouds remain unclear. By analyzing the model simulations from Coupled Model Intercomparison Project Phase 6, here we deforestation-induced changes have a strong latitudinal dependence, with decreased cloudiness in tropics but increased temperate boreal regions. We further disentangle effects influencing simulations. Results deforestation leads to reduction enhancement demonstrate relationship between would be misinterpreted without considering signals. Furthermore, our modeling results are inconsistent recent observational studies, enhanced reduced observations Further efforts explore effect reduce uncertainty could help advance understanding of deforestation.
