We will be organizing a symposium on "Ecology and the evolution of reproductive traits" at the 3rd Joint Congress of Evolutionary Biology (July 26-30 in Montreal). Both ecologists and evolutionary biologists have uncovered a wide range of contexts in which ecology dramatically shapes the evolution of many reproductive traits. We hope that this symposium will make clear the broad importance of ecology for the evolution of reproductive traits and allow researchers to make connections across different systems as well as across ecological and evolutionary contexts. Research themes could include, but are by no means limited to, the plasticity of sexual signals in different ecological contexts, impacts of anthropogenic changes on reproduction, and contemporary evolution of secondary sexual traits. The abstract is provided at the end of the message. Registration is now open, and abstracts can be submitted to be considered for this symposium. Please see 2024 Conference info (evolutionmeetings.org) for meeting info. If you have any questions about the symposium, don't hesitate to contact the organizers. Brian Lerch (blerch@live.unc.edu) Sarah Flanagan (sarah.flanagan@canterbury.ac.nz) Symposium abstract: It is well established that ecological context is critical for shaping the evolution of ecologically relevant traits such as those controlling resource acquisition. However, despite the key role of reproductive traits for shaping fitness outcomes, less attention has been paid to understanding and synthesizing how ecology influences their evolution. Our symposium will fill this gap by highlighting the role of ecology in shaping the evolution of reproductive traits and welcome research on the impacts of reproductive trait evolution on ecological processes. Research themes could include the plasticity of sexual signals in different ecological contexts, impacts of anthropogenic changes on reproduction, contemporary evolution of secondary sexual traits, among many others. By bringing together research on a broad range of taxa and from diverse perspectives, we hope to yield insight into the role of ecology for the evolution of reproductive traits.
