Behaviors are often influenced by both ecology and genetics. Perez et al. tested whether display patterns and the ecology of different species of fiddler crabs influence synchronous waving and whether this a phylogenetic phenomenon. They found that there was no phylogenetic signal in wave display synchronicity, and suggested that signal structure, microhabitat complexity, and different mating systems...
Adaptation to new environments by organisms has been and is of much interest in scientific research. Does the diatom lineage Stephanodiscus niagarae/yellowstonensis follow models compatible with adaptation to a new environment? Voje (2019) shows that in this lineage, none of the current models tested—decelerated evolution, Ornstein‐Uhlenbeck, and random walk—fully explained how multiple traits—valve...
A long‐standing goal for biologists and social scientists is to understand the factors that lead to the evolution and maintenance of co‐operative behaviour between conspecifics. To that end, the fruit fly, Drosophila melanogaster, is becoming an increasingly popular model species to study sociality; however, most of the research to date has focused on adult behaviours. In this study, we set out to...
