Wading Bird Food Availability In Rice Fields And Crawfish Ponds Of The Chenier Plain Of Southwest Louisiana And Southeast Texas, Cullen C. Foley
Wading Bird Food Availability In Rice Fields And Crawfish Ponds Of The Chenier Plain Of Southwest Louisiana And Southeast Texas, Cullen C. Foley
LSU Master's Theses
Wading birds in southwestern Louisiana and southeastern Texas rely heavily on rice fields and crawfish ponds as foraging areas; however, little information exists on food availability throughout the annual crop cycle. The objectives of this study are: 1) Develop a classification for rice and crawfish fields based upon tillage, forage crop (for crawfish fields), water depths, vegetation density, vegetation height, and other visible parameters; 2) Quantify the distribution of rice and crawfish fields in various stages across the landscape through time; 3) Determine the effects of rice and crawfish field types and landscape characteristics on wading bird use; and, 4) …
Population Abundance And Transience Of Selected Coastal Plain Crayfishes, Samantha Lott
Population Abundance And Transience Of Selected Coastal Plain Crayfishes, Samantha Lott
LSU Master's Theses
Crayfish are important for stability, determining ecosystem structure, and ecosystem functions in freshwater habitats. Louisiana has many endemic species of crayfish, but most are poorly described. This study investigated the populations of some of the lesser known crayfishes in the South Central Plains. Specifically, the goals were to examine movement, movement across anthropogenic barriers, and estimate population size of 10 species reported from the area: Procambarus natchitochae, P. vioscai, P. clarkii, P. acutus, P. zonangulus, P. tulanei, P. kensleyi, Orconectes maletae, O. lancifer, and O. palmeri. In combination with a field team, I sampled twelve wadeable streams with DC backpack …
Impact Of Exposure To Weathered Crude Oil And Accumulation Of Pahs In Crawfish (Procambarus Clarkii), Brittany Lynn Chichester
Impact Of Exposure To Weathered Crude Oil And Accumulation Of Pahs In Crawfish (Procambarus Clarkii), Brittany Lynn Chichester
LSU Master's Theses
The number of pipelines transporting crude oil and other refined petroleum products across the U.S. has increased 15.4% from 2004 to 2013. In Louisiana, over 3,450 miles of liquid petroleum pipelines crisscross the state. In January 2013, crude oil was accidentally released from an underground pipeline into Bayou Sorrel, Louisiana. This freshwater wetland is located within the Atchafalaya River Basin which is home to large populations of wild crawfish that could be impacted by the crude oil released. This study aims to assess the potential lethal impacts that crude oil spill may have produced in adult crawfish (P. clarkii) and …
