Abstract The golden‐headed lion tamarin ( Leontopithecus chrysomelas ) is an endangered primate that occurs exclusively in the Atlantic Forest of southern Bahia, Brazil. Its geographic range has been severely reduced by deforestation and its populations are restricted to a human‐modified landscape consisting primarily forest fragments shade cacao Theobroma agroforestry, locally known as cabrucas . In last 30 years, there 42% reduction 60% population size L. , with only 8% habitat represented protected areas.

Habitat modification due to human activities threatens species survival. While some can inhabit habitat patches in anthropogenic landscapes, their occurrence often depends on landscape structure. We assessed the effects of structure brown howler monkey (Alouatta guariba clamitans) an urban scenario. conducted censuses 59 forest from 2014 2016 Rio Grande do Sul State, Brazil. evaluated patch (presence/absence) response composition (forest cover, arboreal crops, areas, open and water) configuration (patch density), considering scale effect. Water, urban, areas were most important predictors presence. Their presence was notably higher landscapes with more water, likely because these consist rural low urbanization, less farming, relatively high cover. Presence howlers positively associated cover negatively related crops. Resource scarcity increased mortality risks pressures, such as domestic dog attacks, electrocution, roadkill land covers may explain relationships. highlight importance conserving increasing protect reliant forested habitats, like monkeys.

Understanding how biological communities respond to human-caused landscape disturbances is urgently needed identify optimal spatial scenarios for preserving biodiversity in anthropogenic landscapes. Forest loss increasingly cited as a major disturbance these landscapes, but its impact on mountain regions with high endemism not well understood. Here we evaluated bird species diversity responds forest ‘La Montaña’ region of Guerrero State, Mexico. We separately assessed the complete assemblage, and distribution three different ecological groups (forest-specialists, habitat-generalists, disturbance-adapted species) whole mosaic. found that assemblage decreased linearly loss. However, responses differed among groups, forest-specialist habitat-generalist increasing more forested following opposite pattern. Similarly, proportion sites occupied by birds loss, site occupancy was independent from cover. Our findings highlight general particular, are those maintain much cover possible.

However, little is known about how habitat alters the relationship between function (BEF relationship) in natural landscape context.

Abstract Edge effects result from the penetration to varying depths and intensities, of abiotic biotic conditions surrounding non‐forest matrix into forest interior. Although 70% world's forests are within 1 km a edge, making edge dominant feature most habitats, there few empirical data on inter‐site differences in responses primates. We used spatially explicit capture‐recapture (SECR) models determine spatial patterns density for two species mouse lemurs ( Microcebus murinus ravelobensis ) landscapes northwestern Madagascar.
