The nest architecture of underground ant nests was studied in Formica pallidefulva. These ants build shallow (30-45 cm deep) nests, which consisted of more or less vertical shafts that bear chambers. Shafts appeared to be modular units...
Hardbottom habitats in the northeastern Gulf of Mexico provide a variety of valuable ecological goods and services including functioning as nursery habitats and providing refuge for resident organisms. In this study, I identified the...
The Florida Gulf of Mexico coast extends over both tropical and subtropical zones resulting in an intermingling of fauna typical to both zones. Cold winter water temperatures historically limited the distribution of many tropical species...
This study examined the reproductive ecology of the red porgy Pagrus pagrus (Sparidae) in the NE Gulf of Mexico and the temporal, bathymetric, and small scale spatial variability of its life history traits and demographics. Almost 4000...
Symbioses are pervasive in life and confer novel adaptive capabilities that enable ecological expansion into unexplored niches. Evolutionary transitions in symbiosis (terminations, origins, host shifts, or changes in relationship...
Indirect genetic effects (IGEs) on traits are present if variation in the social environment provided by others is at least partially due to genetic variation among those individuals. IGEs can result from a variety of interactions...
This dissertation investigated the evolutionary ecology of a type of obligate mutualism, the form of agriculture found in ants. It presents the results of two laboratory experiments with the fungus-gardening ant species, Trachymyrmex...
Sponges are unique filter feeding organisms with complex canal and flagellated chamber aquiferous systems. These systems allow them to specialize in clearing the smallest plankton size class (picoplankton) from the water. Sponges serve...
Genetic variation is a dominant feature in the study of evolution. The presence of variation is embedded at every level, from a single individual all the way to different species. Understanding the mechanisms that allow variation to be...
Deep-sea organisms are increasingly subject to bycatch interactions worldwide. Recent studies have shown that discard mortality can lead to significant declines in deep sea fish stocks, and highlight the inherent vulnerability of deep...
Understanding the maintenance of phenotypic variation within populations has long been a puzzle in evolutionary biology. Many models ignore that fact that animals are not living alone; instead social factors have the potential to alter...
Multiple mating mediates how ecological and evolutionary forces affect populations and there are many explanations for why it is so common. Despite this, taxonomic biases and observational approaches have limited a full understanding of...
