Site-Specific Habitat And Landscape Associations Of Rusty Blackbirds Wintering In Louisiana, Sinead Mary Borchert
Site-Specific Habitat And Landscape Associations Of Rusty Blackbirds Wintering In Louisiana, Sinead Mary Borchert
LSU Master's Theses
The Rusty Blackbird (Euphagus carolinus) has gained notoriety in recent years as one of the fastest declining North American bird species, with a global population loss of as much as 95%. Causes of the decline are not completely understood, but the high rate of forested wetland change in the southeastern United States suggests that wintering habitat degradation may be a primary driver. To better inform management on critical wintering grounds, I surveyed 68 sites in Louisiana where Rusty Blackbirds had been known to occur to address how occupancy changes with habitat type and colonization and extinction rates vary with ground …
Impacts Of Artificial Reef Addition On The Nekton Community Of Louisiana Marsh Ponds: A Before-After-Control-Impact Analysis, Kari Elizabeth Klotzbach
Impacts Of Artificial Reef Addition On The Nekton Community Of Louisiana Marsh Ponds: A Before-After-Control-Impact Analysis, Kari Elizabeth Klotzbach
LSU Master's Theses
Louisiana’s coastal estuaries are dynamic, highly variable environments that provide nursery areas for numerous recreationally and commercially important species. Louisiana’s coastline is constantly changing due to natural and anthropogenic processes, and it is important to know how nektonic species are impacted by such changes. This study sought to assess the effects of introducing a hard substrate artificial reef on the nekton community of a Louisiana estuary. A before-after-control-impact (BACI) design was used to assess the impacts of artificial reef addition on nektonic fishes and crustaceans in four shallow marsh ponds near Empire, Louisiana. Marsh ponds were sampled by purse seine …
