Data from: Wolf in sheep's clothing: model misspecification undermines tests of the neutral theory for life histories

Matthieu Authier, Lise M. Aubry & Emmanuelle Cam
Understanding the processes behind change in reproductive state along life-history trajectories is a salient research program in evolutionary ecology. Two processes, state dependence and heterogeneity, can drive the dynamics of change among states. Both processes can operate simultaneously, begging the difficult question of how to tease them apart in practice. The Neutral Theory for Life Histories (NTLH) holds that the bulk of variations in life-history trajectories is due to state dependence and is hence neutral:...

Data from: Melanin in a changing world: brown trout coloration reflects alternative reproductive strategies in variable environments

Lisa Jacquin, Zoé Gauthey, Vincent Roussille, Michel Le Hénaff, Cédric Tentelier & Jacques Labonne
Melanins are the most widespread pigments in animals but their adaptive significance remains elusive. Recent studies suggest that intraspecific variation in melanin-based coloration reflects individual genetic-based alternative strategies to cope with environment variability, which could be crucial for their responses to climate changes. However, empirical evidence is still scarce. In this study, we tested how skin coloration in natural populations of brown trout Salmo trutta fario would reflect alternative reproductive strategies in different environments. We...
