Yoel E. Stuart
I am an evolutionary ecologist generally interested in the speed and repeatability of evolutionary change. How do populations respond to selection? How long does it take them? And do different populations respond in shared or unique ways? To answer these questions, I combine morphometrics, genomic sequencing, and field based comparative and experimental data collection. For example, my doctoral research showed that novel interactions between native and invasive Anolis lizard species on small islands in Florida generated rapid adaptation over a handful of generations—adaptation that likely allows coexistence. My post-doctoral research showed that adaptation to Vancouver Island lakes and streams by threespine stickleback fish is not as repeatable as we might think, but that knowing something about environmental and genetic variation in different populations does explain some of the (non)parallel evolution we observed.
During my first few years at Loyola, I plan to study (i) phenotypic, genetic, and environmental clines along marine-freshwater ecotones in replicated populations of threespine stickleback; (ii) the morphology, genetics, and biomechanics of habitat choice by threespine stickleback in lakes and streams; (iii) population biology and behavior of native and invasive Anolis lizards to understand the nature of interactions between them; and (iv) data from a 108,000 year fossil lineage of stickleback fish at temporal resolutions on the order of decades–to document microevolutionary change on geological timescales.
