Alan Bergland and I organized and hosted an ASN symposium on the “Causes and consequences of temporally fluctuating selection in the wild” at the Evolution meeting in Providence, RI this past summer. A brief description of the symposium and links to the talks can be found below.
It has long been appreciated selection pressures fluctuate through time. However, the extent to which fluctuating selection pressures promote the long-term maintenance of functional genetic diversity and how functional variation within a species shapes ecological interactions remain open questions. Our symposium seeks to address these basic questions by (i) highlighting recent theoretical developments on the footprints of fluctuating selection and stability of balanced polymorphism, (ii)showcasing recent work identifying abiotic drivers of fluctuating selection from genomic data, and (iii) examining how fluctuating selection, and consequent adaptation, affects ecological dynamics and interactions.
Alan Bergland: Our contemporary understanding of the causes/consequences of temporally fluctuating selection.
Moises Exposito-Alonso: Natural selection in the Arabidopsis genome in present and future climates.
Jason Bertram: Can fluctuating selection stabilize polymorphism at many loci?
Meike Wittmann: Stable polymorphisms due to seasonally fluctuaing selection and their genetic footprint.
Seth Rudman: Repeated phenotypic and genomic evolution in response to seasonality in experiment Drosophila populations.
Carlos Melian: Tangling the webs of life.
And here is my own talk, which was not part of the symposium, but fits with the topic.
Zach Gompert: Measuring selection on polygenic traits in heterogeneous environments.
