Causes and Consequences of Inter-Individual Physiological Variation

Symposium — Tuesday, April 9, 2019 — 1:30 PM - 3:00 PM — Convention Center, Room W312B
Comparative & Evolutionary Physiology Section — Chair: Bernard Rees — Co-Chair:

  Variation among individuals within a species in is an obvious and fundamental characteristic of biology. This inter-individual variation is a result of genetics, development, environment, and their interactions, and it can influence an animal’s ability to avoid predators, compete for resources or mates, or survive changing or stressful environments. When genetically-based, individual variation in a trait represents the raw material upon which natural selection can operate, thereby influencing the evolution of that trait and the adaptive capacity of the species. This exciting, integrative symposium will feature talks covering a broad range of animals (invertebrates, fish, and birds) and considers the role of genetics, development, and environment in physiological adaption. Topics will include how polymorphisms in genes of large effect are involved in ecological dynamics, as revealed by combining functional genomics and physiological approaches with long-term ecological studies; how several genes of small effect can result in physiological adaptation and how different genetic variants combine to result in similarly adaptive phenotypes; and the influence of developmental environment on stress hormone levels, developmental physiology, and adult behavior.
