Long‐term aridity shapes grassland drought resistance and modulates the roles of plant diversity and functional composition

open access: yesJournal of Ecology, Volume 114, Issue 7, July 2026.
Widely studied stability drivers such as plant diversity and functional composition have only partial explanatory power for short‐term drought resistance of above‐ground productivity in grasslands at a global scale. The abiotic context, particularly long‐term aridity, is crucial for understanding ecosystem responses to rainfall variation and can ...

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.
