The influence of littoral zone structural complexity on fish assemblages in Lake Conroe, TX
(Texas A&M University, 1999)
The littoral zone of an East Texas reservoir was surveyed to determine if any characteristic fish assemblages were associated with four different habitat types with varying levels of structural complexity. A stratified ...
Comparing functions of natural and created marshes for shorebirds and wading birds
(Texas A&M University, 1999)
Shorebirds and wading birds were observed November 1997 to April 1998 and September 1998 to April 1999 to compare functional values of natural and created marshes on the Texas coast. Study locations included Aransas National ...

(Texas A&M University, 1999)
A photographic technique was developed to indirectly estimate mass and body condition of the endangered Hawaiian monk seal (Monachus schauinslandi). This project differs from other photogrammetric studies because subjects ...
Abundance of northern bobwhite and scaled quail in Texas: influence of weather and land-cover change
(Texas A&M University, 1999)
Despite intensive study, quail populations across the United States have declined since the 1960s. My analysis of a 21-year (1978-98) data set collected by the Texas Parks and Wildlife Department indicated abundance of ...

Kemp's ridley sea turtles (Lepidochelys kempii) were captured in entanglement nets near Sabine Pass, Tx/La, during May through August, 1996 and 1997. Serial blood samples were collected to: 1) identify physiological effects ...
Fish assemblage structure along environmental gradients in a coastal plain drainage: influences from a reservoir
(Texas A&M University, 1999)
Because most major river drainages are altered by impoundments, it is necessary to understand how such alterations influence structure and function of fish assemblages. Upstream influences of impoundments have only recently ...
