Interacciones murciélago-flor en el Bosque Seco Tropical del Valle del Cauca, Colombia
Biota Colombiana, 2022 El Bosque seco Tropical (BsT) del Valle del Cauca está sometido a fuertes presiones, sin embargo, es un ecosistema en el que se generan procesos importantes para la conservación de la diversidad biológica, mantenimiento de estructura y función de los ecosistemas, producción de alimentos y economía, como la polinización. Entre los polinizadores destacan

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics. [PDF]
Glob Chang Biol, 2023 Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...

Tiny Patch, Big Value: A Small Dry Forest Patch Supports Wildlife Conservation in Guanacaste, Costa Rica. [PDF]
Ecol EvolThis study highlights the biodiversity value of the Murren Reserve, a small tropical dry forest patch in Guanacaste, Costa Rica. Using camera traps and opportunistic observations, researchers documented 32 wildlife species, including federally endangered species like the ocelot (Leopardus pardalis) and puma (Puma concolor), as well as 73 plant species.

American Journal of Botany, Volume 110, Issue 12, December 2023., 2023 Abstract Premise Phylogeographical studies are fundamental for understanding factors that influence the spatial distribution of genetic lineages within species. Population expansions and contractions, distribution shifts, and climate changes are among the most important factors shaping the genetic compositions of populations.

Molecular Ecology, Volume 32, Issue 20, Page 5514-5527, October 2023., 2023 Abstract During the last century, the critically endangered cotton‐top tamarin (Saguinus oedipus) has been threatened by multiple anthropogenic factors that drastically affected their habitat and population size. As the genetic impact of these pressures is largely unknown, this study aimed to establish a genetic baseline with the use of temporal ...

Native palms and trees mediate drought impacts on dry neotropical pastures
Journal of Applied Ecology, Volume 60, Issue 7, Page 1376-1387, July 2023., 2023 Abstract Dry forests are the most threatened biome across the global tropics. Despite their massive conversion into agricultural landscapes, local farmers often retain disperse trees and palms within grazing pastures. Understanding how on‐farm tree cover in the dry neotropics impacts the environmental and productive functions of pastures is key for ...

Roadkill patterns in Latin American birds and mammals
Global Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022 Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...
