The ecological consequences of the reduction of species diversity : experimental approaches

Creator:: Allison, Gary William
Abstract:: The influence of loss of diversity on community dynamics and ecosystem functioning has recently received considerable attention. Although study of biodiversity has a long history within ecology, empirical investigations exploring consequences of loss have been rare. Because many factors confound diversity comparisons, experimental manipulations of diversity offer the most direct...

Phenotypic variation in the sexual attractiveness pheromone of the red-sided garter snake, Thamnophis sirtalis parietalis

Creator:: LeMaster, Michael P.
Abstract:: Pheromones are chemical cues produced by organisms that affect the behavior and/or physiology of conspecifics. The orchestration of reproductive behaviors in many animals depends on the expression of sex pheromones. In insects, intraspecific variation in sex pheromone expression is commonly observed and often influences social interactions between individuals. To what...

An electrophoretic analysis of the coelomic and blood sera of the developing and metamorphosing bullfrog tadpole (Rana catesbeiana)

Creator:: Thornburg, Kent L.
Abstract:: Albumin, as a percent of total proteins in both the coelomic serum and the blood serum, was determined for four groups of developing Rana catesbeiana tadpoles by cellulose acetate electrophoresis. Also, using Folin phenol reagent, the total protein of each the blood serum of metamorphosing tadpoles and the coelomic serum...

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...

The effects of parasites on host behavior : who benefits?

Creator:: Lefcort, Hugh G.
Abstract:: Some parasites may modify the behavior of their hosts. Altered behaviors may: 1) benefit the host in that they defend against the pathogen, 2) benefit the pathogen and represent manipulations of the host response, and 3) benefit neither the host or the pathogen and simply be a product of the...

Linking marine communities and ecosystems : invertebrates mediate nutrient availability in intertidal communities

Creator:: Bracken, Matthew E.
Abstract:: While community ecologists have traditionally focused on local-scale processes, it has become apparent that a broader perspective, which explores the community-level ramifications of material fluxes within and between ecosystems, is necessary to effectively evaluate bottom-up influences on community structure and dynamics. In this dissertation, I employed ecosystem principles to understand...

Biodiversity : illustrations of some concepts, causes, and consequences

Creator:: Russell, Roland B.
Abstract:: Careful analysis and thoughtful synthesis will be necessary for expanding the envelope of ecological understanding. This work is my attempt at communicating both of these, in relation to three questions about our understanding of the structure and dynamics of biological diversity. These questions focus on a) advancing our understanding of...

Linkages between mangrove forests and coral reefs : quantifying disturbance effects and energy flow between systems

Creator:: Granek, Elise F.
Abstract:: Interface habitats are considered valuable natural systems, tightly linked to adjacent habitats through the flow of matter and energy. However, there is limited research on mechanisms of connectivity such as movement of organisms and particulate matter and ways in which anthropogenic disturbance to interface habitats may affect immediate and adjacent...
