Ontogenetic prey change and food habits of two sympatric Texas Ranids: the Southern Leopard frog, Rana sphenocephala, and the Bronze frog, Rana clamitans clamitans
(Texas A&M University, 1996)
The food habits of two sympatric Ranids were investigated for diet composition and tested for the existence of ontogenetic prey changes. Onehundred-thirty-one Southern Leopard frogs, Rana sphenocephala, and 71 Bronze frogs, ...
Development of infaunal populations and below-ground organic matter from three created Spartina alterniflora marshes in Galveston Bay, Texas
(Texas A&M University, 1996)
High rates of wetland loss in the northern Gulf of Mexico have stimulated efforts to create marshes on dredged material. These marshes may not function similarly to their natural counterparts in supporting infaunal populations ...
Techniques for analyzing the effects of translocation on fox squirrels (Sciurus niger)
(Texas A&M University, 1996)
Translocation, the movement of wild animals from one location to another, is thought to be a humane method of controlling damage caused by fox squirrels (Sciurus niger), yet little is known about the effects of translocation ...
Factors contributing to nest predation within habitat of the Golden-checked Warbler, Travis County, Texas
(Texas A&M University, 1996)
Nest failure is considered an important factor contributing to the decline of Golden-cheeked Warblers (Dendroica chrysoparia), yet relatively little is known of the extent of nest predation on this species. In April 1994 ...
Overwintering behavior and movement of immature green sea turtles in south Texas waters
(Texas A&M University, 1996)
Overwintering behavior and movement of immature green sea turtles (Chelonia mydas ) in Lower Laguna Madre, Texas was characterized from October 1992 to March 1993 and November 1993 to March 1994. Radio and sonic telemetry ...
Bioassimilation versus nitrification for the removal of ammonia in aquaculture biofilters
(Texas A&M University, 1996)
Three experiments were performed with 3-mm floating plastic beads as substrate in 15 miniature aquaculture biofilters. The biofilters were fed nutrients to simulate aquaculture conditions and manipulated to encourage ...
Variation of Western Scrub-Jay and Mexican Jay (Corvidae) vocalizations in Texas
(Texas A&M University, 1996)
I recorded vocalizations of allopatric populations of Western Scrub-Jays (Aphelocoma californica texana and A. c. woodhouseii) and Mexican Jays (A. ultramarine couchii) at eight sites in Texas. While many call types were ...
Comparative foraging ecology of white-tailed deer and Angora goats on the Edwards Plateau, Texas
(Texas A&M University, 1996)
This study investigated how seasonal patterns in forage abundance and quality influenced the feeding behavior of white-tailed deer ( Odocolieus virginianus) and Angora goats; two similar-sized ungulates with different ...
Simulation of cholinesterase inhibition caused by sublethal exposure of grassland birds to insecticides in Texas
(Texas A&M University, 1996)
Although insecticide applications have killed wildlife, direct effects of insecticide exposure usually are sublethal. To evaluate factors that contribute to dietary insecticide exposure and to predict sublethal impact of ...
