Data from: Multicollinearity in spatial genetics: separating the wheat from the chaff using commonality analyses

Jerome G. Prunier, Marc Colyn, Kim F. Nimon, Xavier Legendre & Marie Christine Flamand
Direct gradient analyses in spatial genetics provide unique opportunities to describe the inherent complexity of genetic variation in wildlife species and are the object of many methodological developments. However, multicollinearity among explanatory variables are a systemic issue in multivariate regression analyses and are likely to cause serious difficulties in properly interpreting results of direct gradient analyses, with the risk of erroneous conclusions, misdirected research and inefficient or counter-productive conservation measures. Using simulated datasets along with...

Data from: Gut microbiota signatures predict host and microbiota responses to dietary interventions in obese individuals

Katri Korpela, Harry J. Flint, Alexandra M. Johnstone, Jenni Lappi, Kaisa Poutanen, Evelyne Dewulf, Nathalie Delzenne, Willem M. De Vos & Anne Salonen
Background: Interactions between the diet and intestinal microbiota play a role in health and disease, including obesity and related metabolic complications. There is great interest to use dietary means to manipulate the microbiota to promote health. Currently, the impact of dietary change on the microbiota and the host metabolism is poorly predictable and highly individual. We propose that the responsiveness of the gut microbiota may depend on its composition, and associate with metabolic changes in...

Data from: Limited indirect fitness benefits of male group membership in a lekking species

Christophe Lebigre, Rauno V. Alatalo, Carl D. Soulsbury, Jacob Höglund & Heli Siitari
In group living species, individuals may gain the indirect fitness benefits characterising kin selection when groups contain close relatives. However, tests of kin selection have primarily focused on cooperatively breeding and eusocial species, whereas its importance in other forms of group living remains to be fully understood. Lekking is a form of grouping where males display on small aggregated territories, which females then visit to mate. As females prefer larger aggregations, territorial males might gain...

Data from: Dispersal propensity in Tetrahymena thermophila ciliates – a reaction norm perspective

Frank Pennekamp, Katherine A. Mitchell, Alexis Serge Chaine, Nicolas Schtickzelle & Alexis Chaine
Dispersal and phenotypic plasticity are two main ways for species to deal with rapid changes of their environments. Understanding how genotypes (G), environments (E) and their interaction (genotype and environment; G x E) each affects dispersal propensity is therefore instrumental for predicting the ecological and evolutionary responses of species under global change. Here we used an actively dispersing ciliate to quantify the contributions of G, E, and G x E on dispersal propensity, exposing 44...

Data from: High opsin diversity in a non-visual infaunal brittlestar

Jérôme Delroisse, Esther Ullrich-Lüter, Olga Ortega-Martinez, Sam Dupont, Maria-Ina Arnone, Jérôme Mallefet & Patrick Flammang
Background: In metazoans, opsins are photosensitive proteins involved in both vision and non-visual photoreception. Echinoderms have no well-defined eyes but several opsin genes were found in the purple sea urchin (Strongylocentrotus purpuratus) genome. Molecular data are lacking for other echinoderm classes although many species are known to be light sensitive.Results: In this study focused on the European brittle star Amphiura filiformis, we first highlighted a blue-green light sensitivity using a behavioural approach. We then identified...
