Assessing Environmental Issues in Upland Game Birds
(2017-07-31)Wildlife management is essentially the balance between maintenance of habitat and control of population density. To demonstrate the application of multivariate techniques for habitat assessment, I evaluated 4 contemporary ... -
Assessing Herpetofaunal Communities and Species Monitoring in the Rolling Plains of Texas
(2016-08-15)Herpetofaunal communities have been monitored intermittently on the Matador Wildlife Management Area for the past 12 years in an attempt to understand and track species’ responses to habitat changes. This study analyzed ... -
Assessing the impact of feral hog populations on the natural resources of Big Thicket National Preserve
(2009-05-15)The Big Thicket National Preserve (BTNP) is a unit of the National Park Service whose mission prioritizes conservation of its wildlands in the United States. One threat to natural resources of the BTNP has been impacts ... -
Assessing the Impact of Groundwater Pollution from Marine Caves on Nearshore Seagrass Beds in Bermuda
(2010-01-14)This investigation characterized karstic and nearshore environments of Bermuda to describe 1) behavior and periodicity of cave springs; 2) submarine spring water quality; and 3) nearshore marine seagrass density. Caves can ... -
Assessment of estuarine habitats for resident and estuarine-dependent species: tools for conservation and management
(2009-05-15)My research in coastal Ecuador and the northern Gulf of Mexico (GOM) elucidated differences in value of shallow estuarine habitats for fishes and invertebrates. I focused on mangrove and tidal river habitats in Ecuador, ... -
Assessment of Mosquitofish (Gambusia affinis) Downstream of Domestic Wastewater Effluents in the Bayous of Harris County
(2012-02-14)The introduction of pharmaceuticals and personal care products (PPCPs) to aquatic systems has impacted development and reproductive health of fish in many regions of the world. This study investigated western mosquitofish ... -
Assessment of Recreational Fishery in Northeastern Mexico
(2010-01-14)The Northeastern region of Mexico has developed rapidly over the last few decades and reservoir construction has accompanied the growth of the region. As a result, recreational and sport fishing have become very popular. ... -
Assessment of the Contemporary Population Structure and Admixture of Atlantic Swordfish (Xiphias gladius L.) via Mixed Stock Analysis and Bayesian Clustering of Multiple Nuclear SNPS Genotyped through High Resolution Melting
(2012-11-28)North Atlantic and South Atlantic swordfish (Xiphias gladius L.) are currently managed as two stocks separated at 5°N. While previous studies of genetic population structure using both mitochondrial and nuclear DNA confirm ... -
Assessment of the urban public's knowledge of white-tailed deer management in two Texas communities
(2009-05-15)Urbanization throughout much of Texas has resulted in diminished wildlife habitat, resulting from fragmented landscapes. Several previous studies addressed the public’s attitudes concerning the most acceptable white-tailed ... -
ASSOCIATION BETWEEN SHRIMP CATCH PER UNIT EFFORT AND ENVIRONMENTAL VARIABLES IN THE GULF OF MEXICO
(2013-02-04)The commercial shrimp harvest is the second most important fishery in the United States, and eighty percent of this harvest by weight is caught in the Gulf of Mexico (GOM). Survival rate in the post larval stage in GOM ... -
The Association of Virulent Vibrio Spp. Bacteria on Gafftopsail and Hardhead Catfish in Galveston Bay
(2011-10-21)Vibrio vulnificus (Vv) and V. parahaemolyticus (Vp) are gram negative, halophilic bacteria that occur naturally in estuarine waters of Galveston Bay. Both bacteria have the potential to cause infections in humans either ... -
Associations between hydrological connectivity and resource partitioning among sympatric gar species (Lepisosteidae) in a Texas river and associated oxbows
(2009-05-15)The middle Brazos River, located in east central Texas, is a meandering lowland river that contains many oxbow lakes on its floodplain. Flood dynamics of the Brazos River are aseasonal, and faunal exchange during lateral ... -
Associations of watershed and instream environmental factors with aquatic macrofauna in tributaries of the Pedernales River, Texas
(Texas A&M University, 2005-08-29)Intermittent headwater streams serve important functions in semi-arid rangelands, both for humans and wildlife. However, few studies have assessed species-environment relationships for fish and benthic macroinvertebrate ... -
Avian Haemosporidians: Detection, Host, and Climate Association Across Contrasting Regions of Africa
(2018-01-23)Avian haemosporidians make up one of the most widely distributed and diverse vector borne parasite systems, found nearly worldwide. While there has been growth in the use of avian haemosporidians as a model system for ... -
Avian Response to Road Construction Noise with Emphasis on the Endangered Golden-cheeked Warbler
(2011-08-08)Noise pollution can mask or distort bird songs, which inhibits mating success, predator detection, and parental response to begging calls. Road noise can cause lowered density and reproductive success in songbirds. I ... -
Baseline Biodiversity Assessment of Small Mammals, Ticks, and Tick-borne Pathogens in South Texas
(2016-12-06)Texas is a large state comprised of 10 ecological regions that provide diverse habitats to a variety of organisms. Stewardship programs throughout the state maintain healthy habitats for organisms to occupy; yet often these ... -
Bayesian Analyses of Genetic Variation and Population Differentiation in Pacific Swordfish (Xiphias gladius L.) and the Development of High Resolution Melting Assays for Species Identification and Potential Sex-Linked Marker Survey in Istiophorid Billfish
(2014-08-06)Swordfish (Xiphias gladius L.) and istiophorid billfish fisheries in all ocean basins are important commercially and recreationally. Proper assessments of these fisheries are hampered by species misidentification, unknown ... -
Behavior and movement of southern right whales: effects of boats and swimmers
(Texas A&M University, 2007-09-17)Guidelines for sustainable swim-with tourism for large whales are not welldeveloped, as researchers have focused on delphinids. Nations that signed the Convention on Biological Diversity at the Earth Summit in Rio de Janeiro ... -
