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.

estar: An R package to measure ecological stability

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 4, Page 1090-1100, April 2026.
Abstract Assessing ecological stability is a key task in biodiversity monitoring and conservation. Quantifying stability is not trivial because its different aspects can be measured with various properties. However, to date, no software enables measuring different stability properties on ecological time‐series data.
