Non‐Native Species Abundance Decreases the Co‐Occurrence Between Native and Non‐Native Species Through Time at Any Phylogenetic Distance

open access: yesEcology Letters, Volume 28, Issue 4, April 2025.
We investigate how non‐native species can impact native species in a 30‐year time scale by estimating the co‐occurrence between native and non‐native species pairs. We show that interannual variability of non‐native species abundance could be more important than long‐term abundance trends in determining the effects of non‐native species through time ...

open access: yesInsect Conservation and Diversity, Volume 18, Issue 2, Page 161-176, March 2025.
The unregulated trade of terrestrial isopods is a current and significant new threat that leads to the local extinctions of endemic species. Genetic contamination and the introduction and spread of alien species are other secondary threats that could affect native woodlouse populations.

Land Use Change Consistently Reduces α‐ But Not β‐ and γ‐Diversity of Bees

open access: yesGlobal Change Biology, Volume 31, Issue 1, January 2025.
We analyzed a global dataset of 3117 bee assemblages across 157 studies to assess how bee diversity varies among natural, agricultural, and urban habitats. We measured diversity using both the number of bee taxa (taxonomic diversity) and their evolutionary relationships (phylogenetic diversity).
