Data from: Early Plasmodium-induced inflammation does not accelerate aging in mice

Cédric Lippens, Emmanuel Guivier, Sarah E. Reece, Aidan J. O'Donnell, Stephane Cornet, Bruno Faivre & Gabriele Sorci
Aging is associated with a decline of performance leading to reduced reproductive output and survival. While the antagonistic pleiotropy theory of aging has attracted considerable attention, the molecular/physiological functions underlying the early-life benefits/late-life costs paradigm remain elusive. We tested the hypothesis that while early activation of the inflammatory response confers benefits in terms of protection against infection, it also incurs costs in terms of reduced reproductive output at old age, and shortened longevity. We infected...

Data from: Postglacial range expansion shaped the spatial genetic structure in a marine habitat-forming species: implications for conservation plans in the Eastern Adriatic Sea

Aim: Understanding how historical and contemporary processes shaped and maintain spatial patterns of genetic diversity is a major goal for conservation biologists. Here, we characterized the pattern of neutral genetic diversity and we inferred underlying processes in the habitat-forming octocoral Paramuricea clavata in the Adriatic Sea, a peculiar phylogeographic region of the Mediterranean Sea. Location: Eastern coast of the Adriatic Sea. Methods: We genotyped seven microsatellites in 454 individuals of P. clavata from 13 populations...

Data from: Gender equity at scientific events

Florence Debarre, Nicolas Rode & Line V. Ugelvig
Although the proportion of women in science, and in evolutionary biology in particular, has substantially increased over the last century, women remain underrepresented in academia, especially at senior levels. Moreover, their scientific achievements do not always receive the same level of recognition as do men’s, which can be reflected in a lower relative representation of women among invited speakers at conferences or specialized courses. Using announcements sent to the EvolDir mailing list between April 2016...

Data from: A geography aware reconciliation method to investigate diversification patterns in host/parasite cospeciation interactions

Vincent Berry, François Chevenet, Jean-Philippe Doyon & Emmanuelle Jousselin
Cospeciation studies aim at investigating whether hosts and symbionts speciate simultaneously or whether the associations diversify through host shifts. This problem is often tackled through reconciliation analyses that map the symbiont phylogeny onto the host phylogeny by mixing different types of diversification events. These reconciliations can be difficult to interpret and not always biologically realistic. Researchers have underlined that the biogeographic histories of both hosts and symbionts influence the probability of cospeciation and host switches,...

Data from: Positive biodiversity-productivity relationships in forests: climate matters

Herve Jactel, Emmanuel S. Gritti, Lars Drössler, David I. Forrester, William L. Mason, Xavier Morin, Hans Pretzsch & Bastien Castagneyrol
While it is widely acknowledged that forest biodiversity contributes to climate change mitigation through improved carbon sequestration, conversely how climate affects tree species diversity - forest productivity relationships is still poorly understood. We combined the results of long-term experiments where forest mixtures and corresponding monocultures were compared on the same site to estimate the yield of mixed-species stands at a global scale, and its response to climatic factors. We found positive mixture effects on productivity...

Data from: Adaptive diversification of growth allometry in the plant Arabidopsis thaliana

François Vasseur, Moises Exposito-Alonso, Oscar J. Ayala-Garay, George Wang, Brian J. Enquist, Denis Vile, Cyrille Violle & Detlef Weigel
Seed plants vary tremendously in size and morphology. However, variation and covariation between plant traits may at least in part be governed by universal biophysical laws and biological constants. Metabolic Scaling Theory (MST) posits that whole-organismal metabolism and growth rate are under stabilizing selection that minimizes the scaling of hydrodynamic resistance and maximizes the scaling of resource uptake. This constrains variation in physiological traits and in the rate of biomass accumulation, so that they can...
