Rainforest Fragmentation Decreases the Robustness of Plant‐Frugivore Interaction Networks

open access: yesBiotropica, Volume 57, Issue 4, July 2025.
Our study in northern Costa Rica found that larger forest fragments and greater forest cover boost frugivore species richness and strengthen the modularity and robustness of plant–frugivore networks, with three tanager species serving as key species. Consequently, conserving these species and maintaining larger, contiguous forest areas is essential for

Successional Growth Dynamics of Woody Saplings in Tropical Dry Forest Understory

open access: yesBiotropica, Volume 57, Issue 3, May 2025.
The factors that drive sapling growth in tropical dry forest succession remain unclear. Growth rates are higher in the early stages of succession and then decrease. Light and not water seems to be the main factor limiting sapling growth along succession. The successional guild of species and the taxonomic identity as a Leguminosae were the main factors
