Food webs of two Venezuelan clear-water streams with seasonal fluctuations in hydrology
(Texas A&M University, 1997)
Two Venezuelan clear-water streams were sampled to describe resource use by fishes, community interactions, and the effects of seasonal environmental change and resource availability on food web structure. Previous studies ...
Seagrass habitat utilization by fishes in Christmas Bay, Texas
(Texas A&M University, 1997)
Fishes in Christmas Bay, TX were collected during April 1994 through March 1995 to: 1) assess temporal variability in their density, biomass, and diversity; 2) define the relationship between variability in fish population ...
Trace metal concentration in blood of the Kemp's ridley sea turtle (Lepidochelys kempii)
(Texas A&M University, 1997)
Trace metal concentration was analyzed from the blood of 106 critically endangered Kemp's ridley sea turtles (Lepidochelys kempii), captured off the coast of Texas and Louisiana during June-October 1994 and May-August 1995. ...
Comparative toxicities of two common agricultural chemicals to toads
(Texas A&M University, 1997)
Amphibians are limited in their movements compared to other terrestrial vertebrates and are therefore at risk of having entire local populations destroyed by agricultural pesticides. This study provides basic toxicological ...
Effects of supplemental stocking on eastern wild turkey restoration in the Post Oak Savannah of Texas
(Texas A&M University, 1997)
A total of 107 radio-marked eastern wild turkeys (Meleagris 11 v ) was initially or supplementally released from 1994-96 on 5 different study areas to determine the effectiveness of supplemental stocking in the Post Oak ...
Fertilization success and zygote survival in the Galveston Bay population of Crassostrea virginica (Gmelin), the eastern oyster
(Texas A&M University, 1997)
Interactions between the spermatozoa and egg during fertilization include the acrosome reaction, sperm-egg binding and fusing, egg activation, and interactions between gametic nuclear material. Fertilization maybe blocked ...
Herpetofaunal community response to timber harvest practices in an east Texas bottomland hardwood forest
(Texas A&M University, 1997)
Objectives of this study were to assess the effects of different timber harvest practices on an east Texas bottomland hardwood herpetofaunal community 2-5 years post harvest. Emphasis was placed on analyzing the response, ...
The effects of marsh edge and surface elevation on the distribution of salt marsh infauna and prey availability for nekton predators
(Texas A&M University, 1997)
The relative importance of edge and elevation on infaunal distribution patterns within an intertidal collecting infauna on the nonvegetated intertidal and within the marsh at tina Iterniflora salt marsh was examined by ...
Genetic damage and cell cycle perturbations: biomarkers of effect in natural populations
(Texas A&M University, 1997)
Spleen tissue from prairie voles (Microtus ochrogaster) and white-footed mice (Peromyscus leucopus) was analyzed using flow cytometry to assess possible genetic damage and cell cycle disruptions following exposure to ...
Distributions of sperm whales along the continental slope in the northwestern and central Gulf of Mexico as determined from an acoustic survey
(Texas A&M University, 1997)
The traditional method of estimating whale distributions relies heavily on visual sightings along a surface or aerial vessel trackline. Sperm whales are often difficult visual targets because they spend little time at the ...
