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...

A comparative analysis of morphological, physiological, and biochemical adaptation to abiotic stress in intertidal porcelain crabs, genus Petrolisthes

Creator:: Stillman, Jonathon Harris
Abstract:: Organismal tolerance to abiotic environmental stresses contributes significantly to setting the distribution limits of organisms, as demonstrated by vertical zonation patterns in the marine intertidal zone. In this thesis, the ultimate (evolutionary) and proximate (mechanistic) causes of tolerance to temperature and emersion stresses associated with the intertidal zone were examined...

Pre-hatching stages of the tailed frog, (Ascaphus truei) (Stejnegar)

Creator:: Wernz, James George
Abstract:: Description of anuran larvae with the use of staging tables is a common practice in the study of frog life-histories, but there has been no previous description or table of Ascaphus larvae. In comparing Ascaphus larvae to a simplified staging table for anurans it was found that these larvae vary...

Osmotic and ionic regulation in the Dungeness crab, Cancer magister (Dana)

Creator:: Alspach, George Samuel, Jr.
Abstract:: Osmotic and ionic regulation was studied in the Dungeness crab, Cancer magister, after acute exposure to a range of five salinities from 25% to 125% sea water (100% = 32%). Blood, urine and muscle tissue were sampled at 24 and 48 hours after exposure. Analyses were made of blood and...

Polygyny in the bobolink : habitat quality and the adaptive complex

Creator:: Martin, Stephen George, 1941-
Abstract:: The adaptiveness of polygyny in passerines poses a particularly intriguing problem. The altricial young of this group require extended parental care, but young of polygynous pairings generally lack the undivided attention of the male which young of monogamous pairings receive. Polygynous offspring may thus be undernourished and experience greater mortality....

Oceanographic influences on rocky intertidal communities : coastal upwelling, invertebrate growth rates, and keystone predation

Creator:: Sanford, Eric (Eric David)
Abstract:: The influence of large-scale processes on natural communities has become one of the central issues of modern ecology. I combined field and laboratory studies to investigate the effects of variation in coastal upwelling on rocky intertidal communities along the central Oregon coast. I examined whether the growth of intertidal barnacles...

Sulfide metabolism in Lucina floridana, a sulfur symbiont-containing marine clam

Creator:: Larabee, Jeannine Kay
Abstract:: Lucina floridana is an intertidal clam that contains intracellular, sulfur-oxidizing symbiotic bacteria in its gills. These bacteria are chemolithoautotrophic, using the energy from the oxidation of reduced sulfur compounds to power carbon fixation. Although sulfide is an energy-rich compound, it is also toxic to aerobic metabolism and autooxidizes in the...
