Indirect effects of fishing on predators and their prey

Creator:: Stallings, Christopher Derek
Abstract:: Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...

Isolation and characterization of a larval crustacean salt gland from the brine shrimp Artemia salina

Creator:: Lowy, Robert Joel
Abstract:: A method for isolating the salt gland (SG) from the larval brine shrimp has been developed. This extra-renal organ is removed from 5-10% of Stage Inauplii by vortexing after incubating the animals at 37°C for 8 hours in a saline solution buffered with 100 mM sodium phosphate at pH 7.6....

Geographic variation in Dunn's salamander Plethodon dunni Bishop (Amphibia:Caudata:Plethodontidae)

Creator:: Hanlin, Hugh Grady
Abstract:: Life history attributes and apparent distributional patterns suggest that Plethodon dunni exists as small, semi-isolated populations throughout its range. Isozyme and morphological variation in this species was examined to determine any possible geographic trends. Starch gel electrophoresis was utilized to examine genetic variation at 24 isozyme loci in 287 individuals...

An electrophoretic analysis of the coelomic and blood sera of the developing and metamorphosing bullfrog tadpole (Rana catesbeiana)

Creator:: Thornburg, Kent L.
Abstract:: Albumin, as a percent of total proteins in both the coelomic serum and the blood serum, was determined for four groups of developing Rana catesbeiana tadpoles by cellulose acetate electrophoresis. Also, using Folin phenol reagent, the total protein of each the blood serum of metamorphosing tadpoles and the coelomic serum...

Neorickettsia helminthoeca in cell culture

Creator:: Noonan, William Edward
Abstract:: The etiologic agent of salmon poisoning disease was found to be Neorickettsia helminthoeca, although a second organism, the Elokomin fluke fever agent, may also be involved in other areas. Primary cultures of dog leucocytes were found to support the in vitro cultivation of Neorickettsia helminthoeca as were canine sarcoma 503...

Grazing, nutrients, and marine benthic algae : insights into the drivers and protection of diversity

Creator:: Guerry, Anne D., 1973-
Abstract:: Two of the most powerful ways in which humans have altered ecosystems are by increasing productivity and changing the densities of important consumers. The bottom-up effects of productivity and the top-down effects of consumers have been identified as primary determinants of biological diversity, though the links between them remain unclear....

Coral-reef fishes : insights into larval dispersal and invasion ecology

Creator:: Pusack, Timothy J.
Abstract:: Because many coral-reef fishes are observable in situ, are amenable to transplantation, have small home ranges and short generation times, they provide a excellent system to investigate many topics within general ecology, fisheries biology, and conservation biology. The primary goal of this dissertation was to use the coral-reef fishes system...

The chick allantois : an ultrastructural and cytochemical study of an ion transporting epithelium

Creator:: Riddle, Clara Varady
Abstract:: Transporting epithelia have the ability to translocate ions and water from one side of the epithelium to the other against concentration and electrical gradients without disrupting the internal millieu of the cells. The pathway of ions and water across these epithelia is still a major unresolved question. The allantoic epithelium...
