Dayton, Gage Hart (Texas A&M University, 2006-04-12)The distribution and abundance of organisms is influenced by historical, abiotic, and biotic factors. The goal of my dissertation was to determine the distribution of anurans in the Big Bend region of the Chihuahuan Desert ...
-
Saenz, Daniel (Texas A&M University, 2005-02-17)Multiple ecological factors can simultaneously affect species activity and community structure. The goal of my dissertation was to examine the effects of abiotic factors, biotic factors, and succession on anuran communities. ...
-
Laurencio, David Edelman (2009-05-15)The study of species diversity patterns and their causes remains a central theme of ecology. Work conducted over the last few decades has shown that both historical and ecological factors are important in determining species ...

Factors influencing algal biomass in hydrologically dynamic salt ponds in a subtropical salt marsh Miller, Carrie J. (2009-05-15)The interface between land and water is often a dynamic zone that responds to relatively short-term climatic and hydrologic forces. Coastal salt marshes occupy this zone between land and sea and typically are comprised of ...

Metz, Tasha Lynn (Texas A&M University, 2004-11-15)Post-pelagic juvenile and subadult Kemp's ridley sea turtles (Lepidochelys kempii) (20-40 cm straight carapace length) utilize nearshore waters of the northwestern Gulf of Mexico as nursery or developmental feeding grounds. ...
-
Stephens, Sarah Holland (Texas A&M University, 2004-09-30)The critically endangered Kemp's ridley sea turtle experienced a dramatic decline in population size (demographic bottleneck) between 1947 and 1987 from 160,000 mature individuals to less than 5000. Demographic bottlenecks ...

Large River Food Webs: Influence of Nutrients, Turbidity, and Flow, and Implications for Management Roach, Katherine (2012-10-19)Humans impact rivers in many ways that modify ecological processes yielding ecosystem services. In order to mitigate anthropogenic impacts, scientists are challenged to understand interactions among physicochemical factors ...

Seney, Erin Elizabeth (2009-05-15)The Kemp’s ridley sea turtle, Lepidochelys kempii, is recovering from devastating declines that reduced nesting activity from a single-day estimate of 10,000- 40,000 females in 1947 to fewer than 300 during all of 1985. ...
-
Smolensky, Nicole Limunga (2009-05-15)Habitat loss is one of the leading causes of species decline across all taxa and conservation practices require information on population trends. The Mescalero Sands ecosystem, New Mexico, USA, is experiencing landscape ...
-
Subalusky, Amanda Lee (2009-05-15)The American alligator (Alligator mississippiensis) has been frequently studied in large reservoirs and coastal marshes. Large ontogenetic shifts in their diet and morphology have been linked with changes in habitat use, ...
