Density Dependence During Evolutionary Rescue Increases Extinction Risk but Does Not Prevent Adaptation

Ecology Letters, Volume 29, Issue 1, January 2026.
This study investigates how density dependence influences evolutionary rescue in populations facing environmental stress. We found that while density dependence increases extinction risk by limiting population growth, it does not prevent adaptation in surviving populations.

Heat but Not Cold Tolerance Is Phylogenetically Constrained in Greenlandic Terrestrial Arthropods Under Future Global Warming

Global Change Biology, Volume 32, Issue 1, January 2026.
In this study we describe the temperature limits for almost 8% of the Greenlandic arthropod fauna (insects and spiders). By combining this with a DNA analysis and a projection of future climates inhabited by these species we reveal that upwards of 25% of the investigated species risk exposure to stressful temperatures by the end of the century and that

A trait‐based framework to understand and predict the response of wild bee functional groups to anthropogenic landscapes

Insect Conservation and Diversity, Volume 19, Issue 1, Page 56-71, January 2026.
Wild bee functional groups consist of species that are grouped together based on their similarity in multiple nesting and foraging traits. These functional groups have their own specific association with suitable habitats and urban or agricultural landscapes.

Pollinator‐dependence and specialization in three sunbird‐pollinated, fire‐stimulated flowering species

Plant Biology, Volume 28, Issue 1, Page 215-224, January 2026.
Through field observations and experimental verification, we found that three bird‐pollinated plant species with fire‐stimulated flowering specialize in, and heavily depend on, sunbirds for pollination and reproduction. Abstract Fires dramatically reduce both floral resources and pollinator abundance, potentially compromising flowering plant ...
