Léa is a postdoctoral researcher in the Department of Zoology at Stockholm University. She is a behavioural ecologist interested in sexual selection and mating systems in fishes. She received a Master of Science with highest honours from Vrije Universiteit Amsterdam and the University of Rennes 1 and recently obtained her PhD at the University of Pau and the Adour Region, where her research focused on the role of the social environment in shaping variation in sexual selection in lampreys.

Ana is a postdoctoral researcher in the Department of Zoology at Stockholm University. She is mainly interested in the evolution of sexual traits and social behaviours. In her MSc and PhD, at CIBIO (Portugal), she studied the evolution of coloration, and how phenotypes influence social structure and mate choice, using theoretical and empirical work mostly in birds. Currently, she is working with the SpermTree database on the evolution of sperm in animals and studying cognition in different fish species of the Poeciliidae family.

Lennart is a postdoctoral researcher funded by the Wenner-Gren Stiftelserna in the Department of Zoology at Stockholm University.  He is an evolutionary biologist interested in sexual selection and the interaction of evolution and ecology. In his PhD on 'Sex-specific selection in different environments' at TU Dresden he combined experimental approaches in the red flour beetle with meta-analyses. His current project focusses on sexual selection in halfbeaks and the evolution of ornamentation in females.

Madicken combines phylogenetic and experimental approaches to investigate how selection has shaped the tremendous diversity in animal colouration and patterns. In her current project, she is examining the evolution of distinct markings in skates and rays. She is also experimentally testing if eyespots have an anti-predator function in an aquatic environment, using Brown-banded Bamboo sharks, Lemon sharks, and stickleback as model predators.
