A study of the effects of exposure to air on the respiration of two intertidal snails

Creator:: Baker, Carol Dianne
Abstract:: Callistoma costatum and Tegula funebralis, marine intertidal snails from low and high littoral zones respectively, were exposed to air for two, six and twelve hour periods, during which time their oxygen consumption rates were measured. The animals were then immersed in sea water and their respiration rates recorded for a...

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...

Osmotic and ionic regulation in the North American crayfish Pacifastacus leniusculus (dana)

Creator:: Kerley, David Emmet
Abstract:: Osmotic and ionic regulation was studied in the North American crayfish Pacifastacus leniusculus (Dana), stepwise acclimated to increasing salinities. Stepwise acclimation involved transferring crayfish at 48 hour intervals from freshwater to 100% seawater in 20% increments. In experiments where 70% seawater was used, animals were moved directly from 40 to...

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,...

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...

Respiratory adaptations of two macrurousanomuran mud shrimps, Callianassa Califormiensis and Upogebia pugettensis (Decapoda, Thalassinidea)

Creator:: Thompson, Rogene Kasparek
Abstract:: Callianassa californiensis Dana and Upogebia pugettensis (Dana) inhabit estuarine mudflats and are subjected to the hypoxic conditions that prevail during tidal exposure. Metabolic responses for both these species, as indicated by critical oxygen tension, metabolic rate, and tolerance to anoxia were determined. An oxygen macro-electrode and a physiological gas analyzer...

Chemical communication and chemoreception in the Dungeness crab, Cancer magister, and the lined shore crab, Pachygrapsus crassipes

Creator:: Takahashi, Francis Takao
Abstract:: Great importance has been attributed to the visual aspects of sexual communication in semi-terrestrial crabs and although P. crassipes may utilize visual signals, pheromones and chemotactile signals are important in the release of mating behavior. In the subtidal C. magister pheromones seem to mediate both courtship and mating behavior. Visual...

Cardiac and respiratory responses to hypoxia in the crab, Cancer magister (Dana)

Creator:: Stiffler, Daniel Francis
Abstract:: Heart rates and amplitudes were measured for both intact animals (in situ) and isolated hearts (in vitro) of the Dungeness crab, Cancer magister, exposed to low levels in oxygen. Recordings were also made of gill ventilation rate by measuring the frequency of scaphognathite (gill bailer) beats. Both the in vitro...
