Activation, modification and suppression of sex pheromone production in garter snakes

Creator:: Parker, M. Rockwell
Abstract:: Vertebrates communicate with one another and coordinate intraspecific reproduction by using a variety of sexually dimorphic signals, such as plumage, ornaments, sounds, and/or scents. These sexual dimorphisms are maintained by physiological factors, typically sex-specific hormones (though see Chapter 3 for an exception). The purpose of the research in this dissertation...

Architecture, size, and reproduction in plants : a pollination study of Mertensia ciliata (James) G. Don

Creator:: Geber, Monica
Abstract:: I experimentally test the hypothesis that the potential for selfing increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible, profusely-flowering perennial. This follows from the premises that 1) pollen dispersal by pollinators between flowers is limited, and 2) individual pollinators, in this study bumblebees, will visit more flowers per...

Metabolic adjustment to temperature in Strongylocentrotus purpuratus (Stimpson)

Creator:: Ulbricht, Richard Jules
Abstract:: The metabolism of Strongylocentrotus purpuratus (Stimpson) was investigated at several levels of urchin organization. Some experiments were performed with tissues from recently collected (acclimatized) urchins, Other experiments were performed with tissues from urchins held at one of two temperatures (acclimated) for 30 days. Body-component oxygen consumption was measured for bodywall,...

Purine deposition in the skin of juvenile coho salmon, Oncorhynchus kisutch

Creator:: Staley, Kathryn Boyer
Abstract:: This study was undertaken to quantitatively evaluate the relationship between silvering of the skin of juvenile coho salmon, due to the deposition of the purines guanine and hypoxanthine, and adaptation to seawater. It was hypothesized that maximum purine deposition occurs at the time these fish normally enter seawater, that the...

Hydroxyindole-O-methyltransferase (HIOMT) activity in the pineal of chinook salmon (Oncorhynchus tshawytscha)

Creator:: Birks, Eric K.
Abstract:: C-methyltransferase (HIOMT) in chinook salmon (Oncorhynchus tshawytscha). Various body tissues, as well as several morphological brain divisions were tested for the presence of HIOMT. Activity was found in the retina, the dorsal portion of the diencephalon, and in the pineal gland of chinook. However, the activity was significantly higher in...

Physiological alterations following severe hypoxic stress in two species of fresh-water fish

Creator:: Heath, Alan G.
Abstract:: Bluegill sunfish, Lepomia macrochirus, and cutthroat trout, Salmo clarki, were exposed to a rapidly declining oxygen tension for a period of time sufficient to just cause loss of equilibrium in the fish. During recovery from the stress, measurements of oxygen uptake, blood lactic acid, blood glucose, liver glycogen, muscle glycogen,...

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 morphology and sexual maturation of Philometra americana Ekbaum, 1933 (Dracunculoidea:Philometridae)

Creator:: Carter, Richard Thomas
Abstract:: The female Philometra americana Ekbaum, 1933 is a common subcutaneous parasite of the starry flounder, Platichthyes stellatus (Pallas) of Yaquina Bay, Lincoln County, Oregon. Maturation of this worm produces noticeable red cysts subcutaneously between the fin and tail rays and similarly on the operculum. The gravid female penetrates the epidermis...
