(Texas A&M University, 2004-09-30)The coastal zone of Belize is home to the largest recorded number of the threatened Antillean manatee (Trichechus manatus manatus) within the species' Caribbean range. The objectives of my study were: (1) to determine ...
-
(2014-08-05)Understanding how habitat use and reproductive performance vary among age classes is important to understanding population structure and viability. Habitat conditions can affect occupancy and productivity of many songbirds, ...

As mesopredators, stingrays play a crucial role in coastal and estuarine food webs by feeding on benthic prey and being consumed by pelagic apex predators. This effectively links the lower and higher trophic levels together, ...
-
(2022-07-20)Species composition and abundance are important metrics to identify when addressing community structure and ecosystem health due to variable environmental factors. Data collected from the Texas Parks and Wildlife Department ...
-
(2012-07-16)The deep ocean (> 200-m depth) covers more than 65 percent of earth's surface and is known as the largest active carbon sink of the planet. Photosynthesis fixes inorganic carbon into organic rich-compounds to fuel the ...
-
(2009-05-15)Annual abundance of northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) fluctuates drastically in Texas, which complicates a quail manager’s ability to forecast quail abundance for the ensuing ...
