Behavior, association patterns and habitat use of a small community of bottlenose dolphins in San Luis Pass, Texas
(Texas A&M University, 2005-11-01)Photoidentification surveys of bottlenose dolphins (Tursiops truncatus) were conducted from December of 2002 through December of 2003 in Chocolate Bay, Texas, and the adjacent Gulf of Mexico area. The research represented ... -
Behavioral development of dusky dolphins
(2009-05-15)This thesis examines the characteristics of dusky dolphin (Lagenorhynchus obscurus) nursery groups and ontogeny of dusky dolphin calves. Data were collected via boat-based group focal follows of nurseries from October ... -
Behavioral ecology of striped skunk: factors influencing urban rabies management
(2009-05-15)Striped skunks (Mephitis mephitis) are a rabies vector in Texas and efforts are underway to develop an oral rabies vaccination program for skunks. To better understand some of the components necessary, I studied the habitat ... -
Behavioral flexibility of feeding dusky dolphins (Lagenorhynchus obscurus) in Admiralty Bay, New Zealand
(Texas A&M University, 2004-09-30)Foraging theory suggests that hungry animals balance a complex set of costs and benefits when determining what and how to eat. Prey distribution, patch size, and the presence of conspecifics are important factors influencing ... -
Behavioral Performance and Evolution of Feeding Modes in Odontocetes
(2010-07-14)Vertebrate evolution has resulted in a diversity of feeding mechanisms. Cetaceans are secondarily derived tetrapods that have returned to a marine habitat. As a result, they display feeding modes that have converged with ... -
Beyond the Edge of a Niche: The Role of Grazing on Prymnesium parvum Bloom Formations in Two Texas Lakes
(2014-03-25)Prymnesium parvum (golden algae) is a harmful algal bloom species that has caused tens of millions of dollars in natural resource damages in Texas as a result of massive fish kills. This species is present in many Texas ... -
Binational collaboration in recovery of endangered species: the Mexican wolf as a case study
(Texas A&M University, 2004-09-30)The goal of this inductive study was to identify factors that facilitate and inhibit binational collaboration in the recovery of endangered species in the northern Mexico borderlands, focusing on the Mexican wolf (Canis ... -
Bioaccumulation of mercury in pelagic fishes in NW Gulf of Mexico
(Texas A&M University, 2006-08-16)Total mercury (Hg) levels were determined in the tissues of ten taxa of pelagic fishes, with a special emphasis on apex predators (large vertebrates). Highest Hg levels were observed in blue marlin (Makaira nigricans), ... -
Biodiversity Conservation in Sub-Saharan Africa: A Case Study of the African Dwarf Crocodiles (Osteolaemus Spp.)
(2014-11-20)Overexploitation of wildlife is a leading threat to biodiversity in tropical Africa. Effective management requires integrating information on the extent of exploitation, distribution, and status of exploited species. I ... -
Bite performance and feeding kinematics in loggerhead turtles (Caretta caretta) within the context of longline fishery interactions
(2009-05-15)Feeding biomechanics and foraging behavior are likely contributors to loggerhead sea turtle (Caretta caretta) bycatch in the pelagic longline fishery. To investigate these contributions, loggerhead bite performance was ... -
Blue Crab Population Ecology and Use by Foraging Whooping Cranes on the Texas Gulf Coast
(2012-02-14)In 2002, a proposal was submitted to divert water from the confluence of the Guadalupe and San Antonio Rivers to San Antonio, Texas. To investigate the potential impacts of diverting water from the Guadalupe Estuary, my ... -
Breeding biology and habitat associations of the Altamira Oriole and Northern Beardless-Tyrannulet in the Lower Rio Grande Valley, Texas
(Texas A&M University, 2004-11-15)I studied the breeding biology and nesting ecology of the Altamira Oriole (Icterus gularis) and Northern Beardless-Tyrannulet (Camptostoma imberbe), two songbirds inhabiting remnant tracts of Tamaulipan brushland of the ... -
Brown-headed cowbird parasitism on endangered species: relationships with neighboring avian species
(2009-05-15)Brown-headed cowbird (Molothrus ater) parasitism on the endangered black-capped vireo (Vireo atricapilla) is a management concern. Management for black-capped vireos in east-central Texas has focused on habitat restoration ... -
Bull-switching in African Bovid Herds: Assessing Best Practices for Breeding Management in Waterbuck
(2011-10-21)To implement sustainable ex-situ management of big ungulate herds such as African Waterbuck (Kobus ellipsiprymnus), one strategy is to place a vasectomized male with females during the sub-optimal season for breeding and ... -
Canopy Characteristics Affecting Avian Reproductive Success: The Golden-cheeked Warbler
(2012-07-16)Habitat disturbances play a major role in wildlife distribution. Disturbances such as loss of breeding habitat and fragmentation are of particular concern for Neotropical migrant songbird populations. Additionally, ... -
Captive and Wild Observations of the Courtship and Spawning Behavior of Guadalupe Bass Micropterus treculii
(2013-12-06)The Guadalupe Bass Micropterus treculii is native to the Texas Hill Country of central Texas. It is distributed across portions of the Brazos, Colorado, Guadalupe and San Antonio River basins. The Guadalupe Bass is threatened ... -
Cave and cliff swallows as indicators of exposure and effects of environmental contaminants on birds from the Rio Grande, Texas
(Texas A&M University, 2004-11-15)Cave (Petrochelidon fulva) and cliff swallows (Petrochelidon pyrrhonota) were collected along the Rio Grande and evaluated as potential indicators of environmental contamination. The Rio Grande receives toxic substances ... -
Cave swallow (Petrochelidon fulva) nest reuse in east-central Texas
(Texas A&M University, 2005-02-17)Although nest reuse is most commonly associated with costs such as nest instability and increased ectoparasite loads,contrary evidence supports the possibility that nest reuse might provide an adaptive function in the form ... -
