Morphological, Molecular, and Isotopic Approaches to Termite Ecology: A Mangrove Case Study

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Termite communities in Caribbean mangroves, though species‐poor, sustain crucial decomposition and nutrient cycling. Their overlapping niches and stochastic assembly highlight termites' resilience and ecological importance in supporting the functioning of these challenging coastal ecosystems.

Frost Decreases Fruit Production in a Neotropical Savanna: Implications for Frugivorous Bird Abundances

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Severe frost events seem to be happening on average every 5 years, rather than 7 years, as previously reported in the southern limit of the Cerrado, a Neotropical savanna. We conducted this study in the Cerrado, where severe frost events allowed us to compare fruit production and frugivorous bird abundance before and after the disturbance.

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

Unravelling the drivers of island species richness in tropical savannas

open access: yesJournal of Ecology, Volume 114, Issue 4, April 2026.
Murundu island area explains a substantial proportion of the variation in tree and herb richness, consistent with Island Biogeography Theory. On average, a 10% increase in island size corresponds to increases of seven tree species and 7.8 herb species.
