Cardiovascular and respiratory responses of the ghost shrimp, Callianassa californiensis Dana, to the pesticide carbaryl and its hydrolytic product 1-naphthol

Creator:: Estes, Patricia S.
Abstract:: Many environmental factors influence cardiovascular and respiratory activities of crustaceans. The effects of natural stressors (hypoxia, low salinity, high temperature) have been well studied, but the effects of pollutants upon these two organ systems have received less attention. The presence of the pesticide carbaryl (Sevin, Union Carbide, Inc.) and its...

Genetic and phenotypic variation associated with the resistance gene SOD1 in Biomphalaria glabrata, an important intermediate host of Schistosomiasis

Creator:: Bonner, Kaitlin M.
Abstract:: Schistosomiasis afflicts 200 million people and is responsible for 200,000 deaths per year. The infection is caused by a digenean trematode in the genus Schistosoma. The parasite must cycle through both a vertebrate (human) and invertebrate (snail) host to complete the life cycle. My dissertation focuses on the genetic mechanisms...

Adaptive diversity and divergence at frog antimicrobial peptide loci

Creator:: Tennessen, Jacob A.
Abstract:: In this dissertation I study evolutionary patterns at genes encoding antimicrobial peptides (AMPs) in frogs. AMPs are short, amphipathic, cationic, secreted proteins that kill bacteria and other pathogens through a non-catalytic mechanism that involves binding to and disrupting the microbial cell membrane. In many animal taxa, positive selection is much...

Modulation of respiratory burst activity of trout (Oncorhynchus mykiss) phagocytic cells

Creator:: Galvan, Irja S.
Abstract:: In a comparison of the mammalian and fish immune systems many similarities and differences are found. While most of the differences occur in the acquired or lymphoid arm of immunity, the nonlymphoid immune systems of fish and mammals share many similarities. For instance, both animal groups use phagocytic neutrophils and...

All hosts are not created equal : variation in amphibian responses to an emerging fungal pathogen and why it matters

Creator:: Gervasi, Stephanie S.
Abstract:: Emerging infectious diseases are increasing globally and are a threat to human, wildlife, and ecosystem health. The emerging fungal pathogen, Batrachochytrium dendrobatidis (Bd), or amphibian chytrid fungus, is associated with worldwide amphibian population declines and extinctions. Bd has been found on every continent where amphibians exist and has been documented...

Patterns, causes, and consequences of clustering of individual territories of the threespot damselfish, Stegastes planifrons

Creator:: Meadows, Dwayne W.
Abstract:: The threespot damselfish, Stegastes planifrons, maintains individual territories that are clustered on coral patch reefs. My objective was to understand the effects of territory clustering on behavior and fitness. Fish with territories in the center of a cluster had (relative to edge fish): higher mating success (number of eggs), higher...

Oxygen consumption of three species of sea urchins at different temperatures

Creator:: Ulbricht, Richard Jules
Abstract:: Metabolic rate-temperature responses of three related species of sea urchins were determined using oxygen consumption rate measurements. The three species used were Strongylocentrotus purpuratus, Strongylocentrotus franciscanus, and Allocentrotus fragilis. All measurements were made using an oxygen macro-electrode, physiological gas analyzer, and sealed respiratory container. Two series of experiments--field-acclimatized and temperature-acclimated--were...

The maintenance and stability of the shell color polymorphism in the rocky intertidal gastropod Thais (Nucella) emarginata

Creator:: Davis, Charles Lee
Abstract:: Thais (Nucella) emarginata is a common predatory gastropod of the rocky intertidal system of western North America. It is usually found at low tide on top of its sedentary prey, barnacles and mussels. Thais is also highly polymorphic for shell color, and breeding of isolated females has shown that the...

Natural history and evolution of a color polymorphism in Rana pipiens, the northern leopard frog

Creator:: Hoffman, Eric A.
Abstract:: A primary goal of population genetics is to identify the role of microevolutionary forces in producing observed patterns of molecular and phenotypic variation. I conducted four studies in the northern leopard frog, Rana pipiens, to determine just how mutation, migration, genetic drift, and selection influenced, genetic structure of mitochondrial DNA...
