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) ...
Summer fish assemblages in channelized and unchannelized reaches of the South Sulphur River, Texas
(Texas A&M University, 2003)
I used a conceptual model proposed by Schlosser (1987) to compare channelized and unchannelized reaches of the South Sulphur River, Texas. This model suggests that fish assemblage structure can be predicted based on the ...
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 ...
Recolonization of surface-mined lands by pocket gophers (Geomys breviceps) in East Texas Post Oak Savannah
(Texas A&M University, 2001)
Surface mining involves the use of heavy equipment that would theoretically create underground vibrations sensed by pocket gophers. To determine if vibrations cause pocket gopher movement away from areas being mined, ...
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 ...
A genetic approach to the study of population structure in white-tailed deer :: evidence from the Noble Foundation Wildlife Unit
(Texas A&M University, 2003)
A panel of DNA microsatellite markers was developed in order to simultaneously analyze multiple genetic loci in the white-tailed deer (Odocoileus virginianus). These markers were multiplexed and visualized on an automated ...
Breeding and wintering bird occurence in Texas rangelands with special reference to woody plant encroachment
(Texas A&M University, 2003)
Within the past 150 years, rangeland vegetation in Texas has undergone a large-scale conversion from grasslands and savannas to shrublands and woodlands. Concurrently, grassland bird species have shown more declining ...
