Welcome to the Ghalambor lab. We are interested in the processes that lead to and constrain adaptive divergence in natural populations. Our research interests are largely focused on how variation in environmental factors such as temperature, predation, and food availability lead to adaptive differences in suites of integrated traits. We use a combination of field and lab studies to examine both the genetic and environmental basis of differences in behavior, morphology, life history, and physiology traits, and how these traits are integrated at the whole organism level. A common theme in our work is to examine the dual nature of the environment as both an agent of natural selection and a source of phenotypic plasticity. Thus, we strive to understand on one hand the selective pressures favoring adaptive divergence in multiple traits, and how plasticity and trade-offs between traits either constrain or facilitate adaptive divergence across different environmental conditions.  While many of the questions we ask are focused on testing theory, we also apply our work in ways that inform conservation and management. Our study organisms include fish, birds, and insects, our field sites encompass freshwater streams, forests, chaparral and oak woodland habitats. We carry out this work on the island of Trinidad, the California Channel Islands, Colorado, and Ecuador.
