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 ...
Assessment of bycatch associated with the inshore shrimp fishery in Matagorda Bay, Texas
(Texas A&M University, 2000)
Trawl samples were collected from shrimping vessels throughout the Matagorda Bay System during the 1997 and 1998 Spring and Fall inshore commercial food shrimp seasons. These samples were used to estimate the level of ...
Fatty acid composition and distribution in the blubber of bottlenose dolphins (Tursiops truncatus)
(Texas A&M University, 2000)
Bottlenose dolphin (Tursiops truncatus) blubber is heterogeneous, and divided into sub-epidermal, middle, and deep layers. This is consistent with other studies that have shown how odontocete blubber is variable in ...
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, ...
Marginal metabolic scope and growth of hatchery-produced, juvenile red drum by progeny group
(Texas A&M University, 2003)
Nine broodstock groups of red drum Sciaenops ocellatus (each consisting of two males and three females) at a State of Texas fish hatchery spawned 13 concurrent progeny groups for which two performance factors, marginal ...
Cavity availability and use in hardwood forests with emphasis on wood ducks
(Texas A&M University, 2002)
The availability and use of cavities were examined on Tony Houseman State Park and Wildlife Management Area at Blue Elbow Swamp (HWMA), Orange County, Texas, during 1999. Random 0.25-ha plots were used to inventory cavities ...
Thermoregulation in Steller sea lions: an experimental approach
(Texas A&M University, 2004)
The availability of baseline thermal flux data is important for testing hypotheses of endangered species such as the Steller sea lion (Eumetopias jubatus), whose numbers have declined since the 1960s by more than 80% in ...
Woody plant and wintering grassland bird responses to summer prescribed burning in grazed and ungrazed Texas Mid-Coastal Prairies
(Texas A&M University, 2003)
Concerned researchers have argued that winter region habitat losses may exacerbate observed declines of grassland birds on the breeding grounds. Yet few studies have investigated grassland bird habits during the non-breeding ...
