Sex, competition and mimicry: an eco‐evolutionary model reveals unexpected impacts of ecological interactions on the evolution of phenotypes in sympatry

Oikos, Volume 130, Issue 11, Page 2028-2039, November 2021., 2021
Phenotypic evolution in sympatric species can be strongly impacted by species interactions, either mutualistic or antagonistic. Heterospecific reproductive behaviours between sympatric species have been shown to favour phenotypic divergence of traits used as sexual cues. Those traits may also be involved in local adaptation or in other types of species

Biodiversity as insurance: from concept to measurement and application

Biological Reviews, Volume 96, Issue 5, Page 2333-2354, October 2021., 2021
ABSTRACT Biological insurance theory predicts that, in a variable environment, aggregate ecosystem properties will vary less in more diverse communities because declines in the performance or abundance of some species or phenotypes will be offset, at least partly, by smoother declines or increases in others.

A matter of time: Recovery of plant species diversity in wild plant communities at declining nitrogen deposition

Diversity and Distributions, Volume 27, Issue 7, Page 1180-1193, July 2021., 2021
Abstract Aim High levels of nitrogen deposition have been responsible for important losses of plant species diversity. It is often assumed that reduction of ammonia and nitrogen oxide emissions will result in the recovery of the former biodiversity. In Western Europe, N deposition peaked between 1980 and 1988 and declined thereafter.

Populations of high‐value predators reflect the traits of their prey

Ecography, Volume 44, Issue 5, Page 690-702, May 2021., 2021
The extent to which prey traits combine to influence the abundance of predators is still poorly understood, particularly for mixed predators in sympatry and in aquatic ecosystems. In this study, we characterise prey use and distribution in iconic bird (grey wagtails and Eurasian dippers) and fish species (brown trout and Atlantic salmon) to assess ...
