Talk Abstract:

Are some organisms better than others at buffering their fitness against environmental variation in food availability, metabolic stressors, reproductive opportunities, and the like? Are some suites of life history traits more resilient to particular types of environmental variation? I will explore a case study using the butterfly Speyeria mormonia, examining changes in allocation to life history traits of both males and females in response to larval and adult resource stress. I will then tie these patterns to resulting population dynamics in the wild. Finally, I will consider the messages from this case study for the more general question concerning life history resilience.
