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,...

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...

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...

Crossing-over in a reversed acrocentric attached-X chromosome of Drosophila melanogaster

Creator:: Gethmann, Richard Charles
Abstract:: The frequency of exchanges was measured in a reversed acrocentric compound X chromosome that is deficient for interstitial heterochromatin. Previous studies on similar chromosomes containing interstitial heterochromatin have demonstrated a very low frequency of single exchanges, and high frequencies of the double and no exchange classes. It has been postulated...
