Assessing contributions of deterministic versus stochastic processes to local species assembly: A field experiment with annual plant‐dominated communities in gypsum systems

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...

Diversity of Terrestrial Malacofauna, Favorable Habitats, and Relationships With Mollusk Size in Urban Environments of Sergipe, Northeastern Brazil

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
The invasive exotic snail Achatina fulica dominates the terrestrial mollusk community in the city of Aracaju, occurring in all sampled urban habitats and being the most abundant species among the individuals collected. In addition, it exhibited a larger shell size and greater total weight, particularly in back gardens. ABSTRACT Terrestrial mollusks can

Nocturnal Gardeners: Dispersal of Large Seeds by Tent‐Roosting Bats in the Lacandon Rainforest, Mexico

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Tent‐roosting bats in the Lacandon Forest, Mexico, play a previously undocumented role in dispersing large seeds (> 5 mm) from mature forest species with important ecological and human uses. Sampling 21 feeding tents across two protected areas yielded 2137 seeds from 54 species, with seed deposition rates significantly higher under bat tents than in ...

Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...
