CONSEQUENCES OF HABITAT TRANSITIONS ON LOCOMOTIVE TRAIT DIVERSIFICATION AT THE MICRO- AND MACRO-EVOLUTIONARY SCALES
(2015-05-08)
Contemporarily evolving systems provide a unique opportunity to characterize the direction, pattern, and rates of phenotypic change among multiple species. The damming of streams to create reservoirs results in a change ...
Phylogenetic and proximate mechanisms affect darter (Percidae: Etheostomatinae) community structure
(2015-05)
Understanding the relative influences of biotic and abiotic mechanisms responsible for generating patterns of community diversity remains a fundamental theme in ecology. Although studies have recovered patterns of community ...
Social aggression mediated via kin selection and ecological competition in the Amazon molly, Poecilia formosa
(2015-05)
The maintenance of sexual reproduction is still a largely unresolved question in evolutionary biology, and one of the most puzzling aspects of this is the co-existence of sexual and asexual species. This often leads to ...
The Spatial Distribution of, and Upland Impacts on, Playa Wetland Invertebrates
(2015)
Playa wetlands are a type of temporary wetland that are numerous in the Great Plains of the United States. Playa wetlands offer a unique habitat within semiarid grassland ecosystems. My research on the invertebrates of ...
MOLECULAR EVOLUTION OF OXIDATIVE PHOSPHORYLATION GENES
(2015-08)
Physiological processes may serve as mechanistic links between organismal genotypes and phenotypes. Accordingly, adaptations in genes involved in energy metabolism pathways may facilitate the evolution of organismal ...
CONSERVATION, ECOLOGY, AND EVOLUTION OF MIGRATORY BEHAVIOR IN THE PAINTED BUNTING (Passerina ciris)
(2015)
In animal migration studies, determining the migratory connectivity of different species is a crucial step to understand the ecology and evolution of complex behavioral traits as well as to implement effective conservation ...
