Time-lapse and electron microscope study of cultured epithelium subjected to calcium depletion with EDTA and its subsequent recovery

Creator:: Whitehead, Russell Albert
Abstract:: Primary monolayer cultures of chick renal epithelial cells grown on plastic coverslips were reversibly dissociated with the chelating agent ethylenediaminetetraacetic acid (EDTA). The cellular responses during dissociation and reaggregation in Hank's balanced salt solution (BSS) were observed with phase optics and recorded by time-lapse cinemicrography. The epithelial cells grow as...

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...

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...

Investigating variation in immunity and infection risk in wild ungulates

Creator:: Dugovich, Brian S.
Abstract:: In the midst of the sixth mass extinction, understanding wildlife disease spillover is critical to maintaining protected wildlife areas. Studying ecoimmunology and wildlife disease ecology helps to understand immune and disease traits in an ecological context, which is invaluable in preventing pathogen spillover between livestock and wildlife. To investigate this...

Isolation and characterization of a larval crustacean salt gland from the brine shrimp Artemia salina

Creator:: Lowy, Robert Joel
Abstract:: A method for isolating the salt gland (SG) from the larval brine shrimp has been developed. This extra-renal organ is removed from 5-10% of Stage Inauplii by vortexing after incubating the animals at 37°C for 8 hours in a saline solution buffered with 100 mM sodium phosphate at pH 7.6....

Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

Creator:: Tanis, Brian P.
Abstract:: The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

The role of avian predators in an Oregon rocky intertidal community

Creator:: Marsh, Christopher P.
Abstract:: Birds affected the community structure of an Oregon rocky shore by preying upon mussels (Mytilus spp.) and limpets (Collisella spp.). The impact of such predation is potentially great, as mussels are the competitively dominant mid-intertidal space-occupiers, and limpets are important herbivores in this community. Prey selection by birds reflects differences...

Effect of environmental variables on the structure and function of hemocyanin from Callianassa californiensis (Decapoda: Thalassinidea)

Creator:: Miller, Karen Illman
Abstract:: Oxygen binding behavior and subunit association-dissociation of the hemocyanin from Callianassa are sensitive to several environmental variables. Callianassa californiensis is a burrowing estuarine which must survive changes in salinity, temperature and oxygen availability. Previous work on the structure and function of the hemocyanin was done under conditions which did not...
