Run to the Caves: Frog Refuges From Harsh Environments

Biotropica, Volume 58, Issue 6, November 2026.
ABSTRACT The use of caves by primarily nontroglobiont organisms can be critical when the conditions of surrounding epigean habitats deteriorate as a result of synergic effects of climate changes and degradation of native vegetation cover. Under scenarios of unbalanced temperatures, high solar incidence, low humidity and reduced shelter availability in ...

Responses of Water Quality Parameters to El Niño in the Curuá‐Una Reservoir, Amazon Basin

CLEAN – Soil, Air, Water, Volume 54, Issue 10, October 2026.
ABSTRACT The El Niño phenomenon in the Amazon is associated with extreme drought and lower atmospheric humidity, leading to environmental disturbances, such as wildfires and decreased river levels. An exceptionally intense El Niño occurred between 2015 and 2016, reaching historic magnitudes.

Arboreal and Terrestrial Frugivore Vertebrate Assemblage Diversity and Composition Vary With Disturbance Histories in Guianan Forests

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study examined the impact of human disturbances on arboreal and terrestrial fruit‐consuming vertebrate assemblages across three tropical forest sites in French Guiana. While species richness remained consistent across sites, results revealed significant variations in visitation rates and a shift in dominant species.

Modeling climate adaptive habitat connectivity for conservation planning in Colombia

Ecography, Volume 2026, Issue 10, October 2026.
To remain effective under global change, conservation decisions must anticipate shifting climates, species responses to climate change and the dispersal pathways needed to track suitable climate. Yet most assessments of ecological connectivity do not consider how the landscape will change, or, if they do, they only consider a single future time point ...
