Microhabitat Variation in Feeding Places Shape Ant‐Hemiptera Interactions Within Cocoa Agroecosystems

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Ant‐hemipteran mutualistic networks in cocoa crops maintain a stable structural organization across different microhabitats (flowers, leaves, and fruits) and management types. This stability is not intrinsic to the network, but rather an emergent result of the behavior of a few generalist ant species acting as structural buffers.

A new method to control the invasive sun corals (Tubastraea spp.): Underwater compressed‐air blasting

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater compressed‐air blasting is a novel method developed to control invasive sun corals (Tubastraea spp.). The technique removes coral soft tissue without fragmenting colonies, reducing the risk of regeneration and accidental spread. This approach offers a safer and practical tool for managing invasive corals in natural reefs and biofouling ...

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

open access: yesIbis, Volume 168, Issue 2, Page 571-587, April 2026.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.
