  • Connecting microevolutionary processes with macroevolutionary patterns across space and time

    Creator:
    Uyeda, Josef C.
    Abstract:
    Whether microevolutionary processes can explain macroevolutionary patterns has long been a matter of contentious debate. The debate has persisted largely because of the challenging task of connecting microevolutionary theory, which examines population-level phenomena on the generation scale, to data collected across larger spatial and temporal scales. My dissertation research broadly...

  • An Integrated Approach to Gauge the Effects of Global Climate Change on Headwater Stream Ecosystems

    Creator:
    Bury, Gwendolynn W.
    Abstract:
    Climate change is predicted to affect ecosystems, including systems already stressed by human impacts. One ecosystem that is already highly impacted by human land use is the cold headwater stream system of the Pacific Northwest. One method of assessing the function of an ecosystem is by using an indicator species....

  • On the evolution of correlated color traits in garter snakes

    Creator:
    Westphal, Michael F.
    Abstract:
    How complex traits evolve continues to be a major focus of evolutionary investigation. A current topic of debate is the hypothesis that the phenotypic integration of complex traits gives rise to evolutionary constraints. I studied two color traits in the common garter snake, Thamnophis sirtalis, that show a high level...
