Brain and antennal transcriptomes of host ants reveal potential links between behaviour and the functioning of socially parasitic colonies

Molecular Ecology, Volume 32, Issue 18, Page 5170-5185, September 2023., 2023
Abstract Insect social parasites are characterized by exploiting the hosts' social behaviour. Why exactly hosts direct their caring behaviour towards these parasites and their offspring remains largely unstudied. One hypothesis is that hosts do not perceive their social environment as altered and accept the parasitic colony as their own.

Proximity to metal mining is related to aspects of feather coloration but not fluctuating asymmetry in the Russet‐crowned Motmot (Momotus mexicanus) in south‐central Mexico

Ibis, Volume 165, Issue 2, Page 587-601, April 2023., 2023
Mining is present in all major biomes worldwide and overlaps strongly with areas of importance for bird conservation. Mining causes multiple types of environmental disturbance, including habitat alteration, increased human presence and persistent heavy metal pollution. Feather coloration and fluctuating asymmetry (random deviation from perfect symmetry

Linking animal behaviour and tree recruitment: Caching decisions by a scatter‐hoarder corvid determine seed fate in a Mediterranean agroforestry system

Journal of Ecology, Volume 111, Issue 2, Page 400-411, February 2023., 2023
The consequences of seed caching for seedling early establishment are driven by a fine decision‐making process of the disperser. Magpies seemed to ponder the characteristics of the habitat and the seed itself to determine where and how to cache each nut. By doing so, magpies reinforced the quality of seed dispersal effectiveness, as they cached walnuts
