The Effect Of Genetic Relatedness On Mate Selection And Spatial Distribution In The American Alligator, Alligator Mississippiensis, Mark Hoog
Electronic Theses and Dissertations
To date, most genetic studies on the American alligator (Alligator mississippiensis) have focused on population genetics and multiple paternity. There have not been any studies looking at how relatedness affects alligator behavior and movement. This study focused on three main questions: 1) what is the genetic diversity among alligators in this location? 2) can parentage be accurately defined among parents and offspring? and 3) how does individual relatedness affect their spatial distribution? We examined the relatedness of 174 unique individuals from the Okefenokee Swamp Park, in South Georgia, USA. In addition, we placed Telonics® satellite tags on …
Movement In Cats, Valerie N. Plummer
Movement In Cats, Valerie N. Plummer
Electronic Theses and Dissertations
Feral cats (Felis catus) are listed as one of the '100 world's worst invasive alien species'. There are as many as 70-100 million feral cats in the United States as well as an estimated 117-157 million domestic indoor and outdoor cats. Management efforts include a nonlethal feeding and sterilization program known as "trap-neuter-release" (TNR) where cats are surgically sterilized and returned to the environment. Population size and structure, immigration rates, spay/neuter rates, and data on spatial use all play a role in whether TNR is a viable management option. This study focuses on population structure and spatial use. …
The Role Of Artificial Structures In Facilitating Range Expansion Of The Introduced Barnacle Megabalanus Coccopoma In The Southeastern U.S.A., Alicia M. Reigel
The Role Of Artificial Structures In Facilitating Range Expansion Of The Introduced Barnacle Megabalanus Coccopoma In The Southeastern U.S.A., Alicia M. Reigel
Electronic Theses and Dissertations
The barnacle Megabalanus coccopoma is a recent invader of the southeastern U.S.A. from the tropical eastern Pacific. In Georgia, M. coccopoma populations along the immediate coastline often suffer extensive mortality during the winter, but population rebuilding is common after these events suggesting that there may be nearby larval sources. I investigated the hypothesis that artificial structures (i.e., buoys, towers), occurring far enough offshore of Georgia for water temperatures to be moderated by the Gulf Stream, provide refuges for breeding adults of M. coccopoma and can serve as the larval source. I investigated this hypothesis by first developing thirteen microsatellite primer …
