Patterns of habitat use by fishes associated with Sargassum mats in the Gulf of Mexico, with an emphasis on the greater amberjack (Seriola dumerili)
(Texas A&M University, 2002)
Distribution and abundance of fishes associated with Sargassum mats in the NW Gulf of Mexico were examined off northern (Galveston) and southern (Port Aransas) Texas from May-August, 2000. A total of 37 species (17 families) ...
Response of breeding seaside sparrows to fire on the upper Texas Coast
(Texas A&M University, 2002)
Fire is one of the primary tools for managing coastal marshes in parts of the range of the Seaside Sparrow (Ammodramus maritimus). This study examined changes in Seaside Sparrow densities between breeding seasons following ...
Genetic relationships of American alligator populations distributed across different ecological and geographic scales
(Texas A&M University, 2002)
Although much work has been conducted on coastal populations of the American alligator (Alligator mississippiensis), less is known about the population dynamics and genetic structure of alligator populations confined to ...
Community-based conservation planning: the case of the endangered Houston toad in Bastrop County, Texas
(Texas A&M University, 2002)
One of the greatest challenges facing natural resource policy makers is controversy surrounding management of private lands for public goods. Such controversies are perhaps most apparent in the management of federally ...
Temporal patterns and types of sperm whale (Physeter macrocephalus) codas in the Northern Gulf of Mexico: a metadata analysis
(Texas A&M University, 2002)
Variation in sperm whale codas, short rhythmic series of clicks, was examined across annual, seasonal, and time-of-day temporal categories. Recordings were made from towed linear arrays during two-week seasonal cruises ...
Multiple prey traits, multiple predators: keys to understanding complex species interactions
(Texas A&M University, 2002)
Species interactions generate both natural selection and ecological community structure. Among the more interesting species interactions are those that create adaptive tradeoffs-where phenotypes conferring improved ...
Early periphyton accumulation and composition in a wastewater effluent dominated stream: effects of season, distance from discharge, and flow regime
(Texas A&M University, 2002)
Municipal wastewater effluent can alter the receiving stream's algal production and community structure by affecting natural hydrologic patterns and nutrient availability. In this thesis, early succession periphyton ...
Habitat associations of fish assemblages in the Sulphur River, Texas
(Texas A&M University, 2002)
As part of an instream flow study, information on summer distribution of fishes and habitat variables was collected from six sites at each of three flows in the Sulphur River, Texas. I evaluated (1) spatiotemporal ...
Homesite attendance as a measure of alloparental and parental care by gray wolves (Canis lupus) in northern Yellowstone National Park
(Texas A&M University, 2002)
Cooperative breeding in mammals is quite rare. Helping with care of young by alloparents tends to be associated with monogamous family groups where dispersal of alloparents is delayed. This study focused on homesite ...
Fatty acid composition of common dolphin blubber
(Texas A&M University, 2002)
Sixty-five fatty acids were quantified in the blubber of two closely related species of common dolphin (Delphinus delphis, D. capensis) from the coast of southern California. Dolphins were grouped according to gender, ...
