Avian influenza (AI) is an infectious disease of birds caused by type A influenza viruses. These AI viruses (AIV) commonly infect poultry and wild birds; however, some AIV strains have infected and caused mortality in a ...

Environmental parameters related to growth of submersed aquatic vegetation in the lower Mobile Delta, Alabama

Newbolt, Chad (2005-12-15)

Light availability and soils influence growth of submersed aquatic vegetation (SAV). My objectives in this study were to determine relationships between these environmental parameters and distribution and abundance of ...

Estuaries as habitat for a freshwater species: Ecology of largemouth bass (Micropterus salmoides) along a salinity gradient

Norris, Alicia (2007-05-15)

Similar to the freshwater systems largemouth bass inhabit, the largemouth bass is a popular recreational sportfish in estuarine environments, like the Mobile-Tensaw Delta. However, catch rates of large (= 2.3 kg) largemouth ...

Exploring the role of carotenoid pigments in physiological function and color signals

Wildlife openings are forest openings created predominately for game species. Many bird species, some of which are exhibiting population declines, utilize openings during the breeding season. Openings can vary in size, ...

Response of Vegetation and Avian Communities to Retention Harvests in a Mixed-pine Forest in Northern Alabama

Sterling, Rachelle (2013-05-14)

Retention harvests are commonly used silvicultural methods that mimic natural disturbance and create a mosaic of mature and early-successional habitats which may simultaneously provide habitat for both mature-forest and ...

Restoration of Native Plants Through Chemical Control of Alligatorweed (Alternanthera philoxeroides) at Eufaula National Wildlife Refuge

Allen, Shannon (2006-08-15)

Moist-soil management is a technique used to improve quality of wetland habitats for a variety of waterbird species, but alien invasive plant species may impact success of moist-soil management. Alligatorweed (Alternanthera ...
