Abstract The spatial heterogeneity and variability of environmental conditions in the Colombian Amazon, located north-eastern South America, are key factors explaining high diversity mammal species, representing 49% those reported for Colombia. In recent decades, Amazon forest system has experienced accelerated transformation due to deforestation, fires, extensive cattle ranching, road infrastructure development, leading degraded natural habitats reduced connectivity among populations large mammals areas ecologically important these species. However, there been a lack functional analysis Andean Amazonian floodplain landscapes using multi-species approach that considers predator-prey relationships representative groups such as felids wild ungulate To address this gap, we utilized occurrence data focal species including jaguar, lowland tapir, white-lipped, collared peccaries. We developed potential distribution models, conducted binarization processes, analyzed morphological patterns, constructed resistance matrix.

Abstract The lack of knowledge about the distributional patterns threatened ungulates hinders implementation effective strategies for conservation their populations in Neotropical savannas. Orinoquia is one those ecoregions with limited data, poorly represented Colombian National System Protected Areas. Nevertheless, savannas serve as habitat 70% ungulate species reported country. objective our research was to identify presence lowland tapir ( Tapirus terrestris ) and evaluate its representation different land cover types within Areas (PAs) department Vichada. To accomplish this, we: i modeled ecological niche using MaxEnt algorithm, ii classified potential distribution into three zones suitability, iii assessed representativeness suitability savanna ecosystem PAs. suitable area 134,575 km 2 , most representative landscapes being: (118,125 87.8%) evergreen broadleaf forests (12,550 9.3%). Furthermore, (2,925 2.2%) Natural Reserves Civil Society. Our results highlight importance private initiatives a complementary strategy government PAs well contributing functional connectivity on regional scale. We provide information spatial ecology an input practitioners planning eastern Colombia.

The Colombian Orinoco region is one of the most important areas for agricultural development in country. department Vichada, particular, has experimented with a continuous growth commercial tree plantations, which covered around 110589 ha by 2021. However, potential effects these land use changes on native mammals are not well understood. Here, we compared diversity and composition terrestrial between gallery forests, natural savannas Puerto Carreño. We deployed 64 camera traps eight months (5840 days) August 2023 March 2024, obtaining 1087 independent records 23 medium large-sized mammal species (forest: 775, plantations: 295, savanna: 17). Diversity measures indicated that forest almost double folded an estimated richness 26 13 species, respectively, while only detected four (5 estimated). difference plantations was significant. common were spotted paca (C. paca) white-lipped peccary (T. pecari). On other hand, white-tailed deer (O. virginianus) crab-eating fox thous) plantations. Our results reaffirm importance riparian forests conservation productive landscapes Altillanura confirm used several two which, even more frequently than covers. reflect similar as non-productive landscapes, presence five threatened highlights this study area need implementing programs. recommend strengthening monitoring to analyze afforestation cover.

Colombia is the world’s fourth most biodiverse country for mammal species. This condition evidenced in high number of species reported specific groups, such as tapirs. The considered a hotspot genus Tapirus , reporting three four scientifically valid ( bairdii T. pinchaque and terrestris ). Approximately ~ 49% Colombia’s natural ecosystems have been transformed by human activities, 16% national territory designated protected areas (PAs). In this context, ecological connectivity between PAs essential to improve conservation threatened large mammals tapirs contribute effectiveness management these current scenario global change. We developed models tapir identified critical conserve connections Colombia. To end, we constructed i ) distribution species, ii movement resistance surfaces, iii mapped least-cost corridors (LCCs). also used circuit locate priorities restoration opportunities, estimating equivalent connected area (ECA) index. Our results provide national-level assessment functional could be an input guide efforts related conservation, restoration, implementation tools that facilitate through landscapes. Implementing actions meeting goals post-2020 biodiversity framework, which aims achieve effective, ecologically representative, well-connected, equitably managed PAs.

Fire plays a crucial role in shaping multiple ecological processes native savannas. Still, the natural fire regime Neotropical savanna of South America is being altered by climate variability, resulting reduced precipitation and increased mean temperatures. In recent years, an increase duration, intensity, frequency, extent wildfires American savannas has been reported. However, knowledge ecology landscapes their impact on habitats large mammals limited or non-existent. This study investigates suitability habitat for Tapirus terrestris high plains landscape department Vichada eastern Colombia. We used MaxEnt algorithm to model niche lowland tapir then classify land covers into low, medium, probability species occurrence. assessed representativeness occurrence frequency detection burned areas within classified tapir. Our results indicate that significantly affect high-suitability such as forest shrubland covers. The effects these cover types would reduce resource supply cause displacement individuals new which could exposure threats hunting pathogens from domestic animals. research underscores need targeted conservation strategies mitigate wildfire impacts preserve critical vulnerable species.
