Prof. Antoine Guisan was interviewed by the RTS (CQFD show) to speak about the problems of upland plants as a result of climate change.

Prof. Erica van de Waal and Dr Charlotte Canteloup published an article in Nature Communications showing how prestigious individuals and leaders strongly influence behavioral diffusion processes not only in humans but also in wild primates communities.

Some ant colonies are led by a single queen while others have several. Two studies conducted respectively by Prof. Michel Chapuisat and Prof. Laurent Keller published in Current Biology and Nature Ecology & Evolution look at groups of related genes - supergens - controlling these variations in the social organization of ant societies. They appeared hundreds of thousands of years ago and have been conserved until today.

Dr Eric R. Lucas, former Postdoctoral fellow at the DEE and Prof. Laurent Keller published an article in Functional Ecology entitled The co-evolution of longevity and social life. In this paper they review how living in social groups can influence the evolution of senescence and longevity by affecting key life‐history parameters such as extrinsic mortality and the cost of reproduction. They argue that benefits of social life in terms of increased survival are common only in species in which life in large groups is already the norm, most likely because these species have adapted to depend on social groups. The only effect of sociality on longevity that has been convincingly demonstrated is increased longevity in high‐ranking individuals from cooperatively breeding vertebrates and social insects, who benefit from the protection and support of their non‐breeding helpers. In contrast, helpers in these species usually do not show evidence of increased longevity, with the exception of naked mole rats where both breeders and helpers live much longer than related solitary species.

Dr Ornela De Gasperin and colleagues from the Chapuisat group performed an experiment in which they tested the effect of winter conditions on the success of ant queens originating from single- and multiple-queen colonies, respectively. The results, published in Biology Letters, support the assumption that harsh environments constrain independent reproduction of members of cooperative breeding groups.

An international team of researchers co-led by Prof. Waterhouse published in the journal Genome Biology, the results from the i5k pilot project, an initiative to sequence and annotate the genomes of 5’000 species of insects and other arthropods. The study presents 28 new arthropod genomes and comparative analyses across 76 species spanning 500 million years of evolution that reveal dynamic genomic changes pointing to key factors behind their success and opening up many new areas of research.
