A study of the effects of exposure to air on the respiration of two intertidal snails

Creator:: Baker, Carol Dianne
Abstract:: Callistoma costatum and Tegula funebralis, marine intertidal snails from low and high littoral zones respectively, were exposed to air for two, six and twelve hour periods, during which time their oxygen consumption rates were measured. The animals were then immersed in sea water and their respiration rates recorded for a...

An experimental test of optimal outbreeding in the harpacticoid copepod Tigriopus californicus (Baker)

Creator:: Brown, Alice F.
Abstract:: Hypotheses concerning relative costs of inbreeding and outbreeding were evaluated for the harpacticoid copepod Tigriopus californicus, which inhabits high intertidal tidepools. Field studies indicate high variation in biotic and abiotic parameters among pools. These findings coupled with previous information about very low dispersal rates and local adaptations to individual pools...

Population genetics, ecology and evolution of a vertebrate metacommunity

Creator:: Manier, Mollie Kim
Abstract:: Population genetic structure is widespread in many organisms and can be found at small spatial scales. Fine-scale differentiation is the result of ecological and evolutionary processes working together to produce an overall pattern, but the relative importance of these factors in population differentiation is poorly understood. The goals of my...

Macroscale to local scale variation in rocky intertidal community structure and dynamics in relation to coastal upwelling

Creator:: Freidenburg, Tess L.
Abstract:: Understanding how large-scale processes (>100 kms) influence ecological communities is currently a major focus in ecology. In marine systems, coastal upwelling, a large-scale oceanographic process in which surface water pushed offshore by winds is replaced by cold, nutrient-rich water from depth, appears to cause variation in rocky intertidal communities. Along...

Bottom-up and top-down forces in tidepools : the influence of nutrients, herbivores, and wave exposure on community structure

Creator:: Nielsen, Karina Johanna
Abstract:: The relationship between nutrients and community structure is poorly understood in open-coast habitats. I created a system of artificial tidepools, of identical age and physical dimensions, at two sites that differed in wave exposure, and manipulated nutrient levels and the abundance of herbivores. Using these unique field mesocosms, I explored...

Factors affecting the dynamics and regulation of coral-reef fish populations

Creator:: Webster, Michael Scott
Abstract:: Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...

Geographic variation and mass mortality in the black abalone : the roles of development and ecology

Creator:: Tissot, Brian N. (Brian Nelson)
Abstract:: Studies of geographic variation are central to understanding ecological and evolutionary processes. Geographic variation in the shell of the black abalone (Halioth cracherodii), a marine intertidal gastropod, involves both clinal and local variation along the eastern Pacific coast in the number and size of tremata (=respiratory pores) on the shell....

Chemical signaling and pheromone evolution in plethodontid salamanders

Creator:: Palmer, Catherine Anne
Abstract:: My dissertation focuses on the evolutionary forces that have shaped the chemical signaling system of plethodontid salamanders. Pheromones mediate two phases of plethodontid reproduction: mate attraction prior to courtship and female persuasion during courtship. Substrate-borne chemical signals are believed to play an important role in mate attraction for these animals....
