Effect Of Thermal Stress On Larvae Of Patiria Miniata (Brandt) Including Studies On Induction Of Spawning, Development And Larval Tagging, Kenneth A. Simon Jan 1974

Effect Of Thermal Stress On Larvae Of Patiria Miniata (Brandt) Including Studies On Induction Of Spawning, Development And Larval Tagging, Kenneth A. Simon

University of the Pacific Theses and Dissertations

It has been estimated by the Department of the Interior that by 1985 nearly one-quarter of all surface water in the United States will be used in removal of waste heat produced in electric generation. This will involve subjecting tremendous quantities of plankton to rapid fluctuations in temperature. The biological effect of such treatment on primary productivity and composition of zooplankton populations is not fully understood. To date little published information is available on the effect of rapid temperature fluctuations on plankton. Such temperatures are the result of heat exchange found in the cooling system of a steam-generating electric station. …


Fitness Theory And Aspects Of Behavioral Ecology In Two Sympatric Pacurus Species At Dillon Beach, California : Decapoda, Anomura), John Erickson Warner Jan 1974

Fitness Theory And Aspects Of Behavioral Ecology In Two Sympatric Pacurus Species At Dillon Beach, California : Decapoda, Anomura), John Erickson Warner

University of the Pacific Theses and Dissertations

In the present study, aspects of the behavior and ecology of two sympathetic intertidal hermit crabs, Pagurus hirsutiusculus and Pagurus samuelis were studied with the intention of expanding the use of fitness set analysis to other species, particularly extending studies over the entire breeding season.


Population Ecology Of The Littoral Fringe Gastropod Littorina Planaxis In Northern California, Russell James Schmitt Jan 1974

Population Ecology Of The Littoral Fringe Gastropod Littorina Planaxis In Northern California, Russell James Schmitt

University of the Pacific Theses and Dissertations

Life history patterns of individual organisms are the result of natural selection and should be correlated with particular physical and biological characteristics of habitats in which they live. The littoral fringe is known to be the most severe physical habitat in the intertidal zone, and it is expected that organisms in it should have population characteristics associated with selective response to physical adversity rather than biological interaction. Ecological studies of populations of Littorina planaxis were made in the Dillon Beach and Bodega Head areas. The study localities differed principally in extent of wave exposure rather than geographical location.
