L’IRD, nouvelle tutelle du laboratoire EDB

5 chercheurs de l’Institut de Recherche et Développement (IRD) ont rejoint le laboratoire EDB depuis le 1er Janvier 2017. Ils enrichissent ainsi l’équipe AQUAECO avec laquelle ils partagent les thèmes de recherche sur l’écologie des communautés de poissons et leurs réponses aux changements globaux. L’arrivée de ces chercheurs renforce les travaux menés au sein d’EDB sur les pays du Sud, en particulier sur la zone amazonienne via le labex CEBA. Les interactions établies de longue date entre les collègues de l’IRD et l’équipe Aquaeco, s’enrichiront sous peu de nouvelles interactions avec l’ensemble des chercheurs du laboratoire.

Colour polymorphism is associated with lower extinction risk in birds [Globale Change Biology]

Christophe Thébaud & Lisa Jacquin

Colour polymorphisms have played a major role in enhancing current understanding of how selection and demography can impact phenotypes. Because different morphs often display alternative strategies and exploit alternative ecological niches, colour polymorphism can be expected to promote adaptability to environmental changes. However, whether and how it could influence populations’ and species’ response to global changes remains debated. To address this question, we built an up-to-date and complete database on avian colour polymorphism based on the examination of available data from all 10,394 extant bird species.(...)

State of the World’s Plants 2017 [Royal Botanic Gardens - Kiew]

Guillaume Besnard (Page 36)

Plants underpin all aspects of our everyday life — from the food that we eat, to the clothes that we wear, the materials we use, the air we breathe, the medicines we take and much more. These essential services provided by plants are far too often taken for granted. This is the second annual report in which we have scrutinised databases, published literature, policy documents, reports and satellite imagery to provide a synthesis of current knowledge on the world’s plants.

Confronting the risks of large-scale invasive species control [Nature Ecology & Evolution - Comment]

Julien Cucherousset

Large-scale invasive species control initiatives are motivated by laudable desires for native species recovery and economic benefits, but they are not without risk. Management interventions and policies should include evidence-based risk–benefit assessment and mitigation planning.
