Hypopigmentation in mantled howler monkeys Alouatta palliata (gray 1849): First documented cases of whole-body leucism in South America. [PDF]
Ecol Evol, 2022 Hypopigmentation in vertebrates is the result of genetic impoverishment and it is associated with isolated populations and environmental stressors. In mantled howler monkeys Alouatta palliata (Gray 1849) there are records of hypopigmentation in Mexico and Costa Rica but this is the first documented record of whole‐body leucism in South America in a ...

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.

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 ...

Hormigas: relaciones especies-área en fragmentos de bosque seco tropical [PDF]
Neotropical Entomology, 2009 Analizamos el efecto de la fragmentación sobre las relaciones especies-área y frecuencia relativa-área de hormigas en nueve fragmentos de bosque seco tropical en la cuenca media del río Cauca, Colombia. La riqueza y frecuencia relativa total de hormigas se correlacionó positivamente con el área más no con el grado de aislamiento.

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 ...
