Population dynamics and long-term impacts of the invasive zebra mussel (Dreissena polymorpha) in a subtropical reservoir
(2018)
As humans continue to advance through the Anthropocene, we find that among other impacts, the rate at which species expand their range and are transplanted into new environments continues to increase. As the frequency of ...
PALEOECOLOGY OF MEDIAL CRETACEOUS DINOSAURS FROM WESTERN NORTH AMERICA
(2018-08)
This dissertation is broken into four chapters. In chapter I, I cover background literature and set the framework for the following chapters by describing the relationship between dinosaur ecology and ontogeny. In chapters ...
INSIGHTS FROM LAMPREY INTO DEVELOPMENT AND EVOLUTION OF GLIA AND CRANIAL SENSORY GANGLIA
(2018-05-11)
During evolution, animal nervous systems have become increasingly complex. This complexity is based on the cumulative diversity of neural cells and the emergence of new nervous system structures. Among animals, vertebrates ...
FROM COOPERATION TO COMPETITION: HOW MICROBES AND INVERTEBRATES INTERACT IN A TROPICAL FOREST
(2018-05)
Microbes and invertebrates are “the little things that run the world” (Wilson 1987, Moreau 2017), but the intricacies of how these organisms impact our environment remains underexplored. Here I investigate how microbes and ...
THE ROLE OF DIVERGENT GENITAL MORPHOLOGIES IN REPRODUCTIVE ISOLATION
(2018-05-11)
How a single ancestral species can give rise to new, separate species remains a major outstanding question in evolutionary biology. Understanding speciation requires identifying how reproductive isolation (RI) is initiated ...
Biophysical mechanisms for the generation of electrosensory and communication signal in the weakly electric fish Eigenmannia virescens
(2018-05-03)
The weakly electric fish Eigenmannia virescens generates electric organ discharges (EODs) to navigate and communicate. The EODs are brief monophasic voltage pulses with brief inter-pulse intervals, resulting in a sinusoidal ...
