Fallen Logs Act as Natural Bridges Over Rivers in a Tropical Wet Forest

Biotropica, Volume 58, Issue 1, January 2026.
We studied how vertebrate species used logs as bridges over rivers in a tropical rainforest. Most mammals present in the area used logs, but the frequency and probability of crossing varied widely among species, between seasons, and in relation to the dimensions of the log and the river below.

Strong Variation in Land‐Use Change Impacts on Tropical Avian Phylogenetic Diversity Between Ecoregions Highlights the Need to Sample Large Spatial Scales

Global Change Biology, Volume 32, Issue 1, January 2026.
Forest conversion for agriculture is a major cause of biodiversity loss in the tropics, but its impacts depend on how broadly they are measured. Using data from across Colombia, one of the most biodiverse countries in the world, we examined how deforestation for cattle farming affects the evolutionary history of bird species.

Recovering European River Invertebrate Communities Homogenize or Differentiate Depending on Anthropogenic Stress

Global Change Biology, Volume 32, Issue 1, January 2026.
(a) European river invertebrate communities showed an average increase in local richness over time (1994–2023), indicating partial local recovery following the alleviation of anthropogenic stress (e.g., point‐source pollution). However, this local recovery was not accompanied by increases in β‐diversity, likely due to persistent, unaddressed stressors,
