Evolution, Ecology, Aquatic Diversity, Phenotypic Plasticity, Environmental Change, Adaptive Divergence
- Research Summary
We address questions about how biodiversity arises in single populations of fishes composed of alternate ecotypes that live in different lake habitats. We study the factors that regulate the formation of specialized ecotypes and have expanded theory by evaluating the role of phenotypic plasticity in adaptive divergence. Experience with fish resource polymorphism since 1993 uniquely positions us to investigate how different ecotypes evolve and may be converted into new species. We also study the effects of commercial fishing on natural populations. This work is important because diversity within populations is rarely considered in the contexts of ecological function, management and conservation, or its capacity to buffer populations from adverse effects of environmental change.
