Differences in Colour Pattern, Behaviour and Gene Expression in the Brain Suggest Divergent Camouflage Strategies in Sympatric Reef Fish Species

open access: yesMolecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT Camouflage is a critical survival strategy that helps to evade predation and increase hunting success. Background matching and disruptive colouration are different camouflage strategies that are subject to different selective pressures and can drive divergence in their associated traits such as colour pattern and behaviour.

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).

Genetic analysis of museum samples suggests temporal stability in the Mexican nonbreeding distribution of a neotropical migrant

open access: yesJournal of Avian Biology, Volume 2025, Issue 1, January 2025.
Seasonal migration is highly labile from an evolutionary perspective and known to rapidly evolve in response to selective pressures. However, long‐distance migratory birds rely partially on innate genetic programs and may be constrained in their ability to alter their migratory behavior.

Comparing carbon offsets and livelihood benefits in a long‐term reforestation project: Agroforestry versus native timber versus enrichment planting

open access: yesEcological Solutions and Evidence, Volume 5, Issue 3, July–September 2024.
Looking at different reforestation methods over 14 years in an Emberá Indigenous community in Panama we found that plots with native timber mixtures and monocultures stored three times more carbon than those with agroforestry or natural regrowth. Natural regrowth was less valued by participants due to the abundance of pioneer species, but it helped ...
