Abstract/Description

Many species prey upon the threatened gopher tortoises, including the Red Imported Fir Ants Solenopsis invicta. While human alterations to native habitat have led to a decline in gopher tortoises, “disturbance specialists” like S. invicta often thrive on such changes. This study examines three ant surveys at gopher tortoise burrows within a section of residential “greenway” in southeastern Florida before and after “reduction mowing”. While the presence of S. invicta did decrease aftrer the...

While human alterations to native habitat have led to a decline in gopher tortoises, “disturbance specialists” like S. invicta often thrive on such changes. This study examines three ant surveys at gopher tortoise burrows within a section of residential “greenway” in southeastern Florida before and after “reduction mowing”. While the presence of S. invicta did decrease aftrer the reduction mowing, the numbers of native ants and ant species richness in general showed a significant decline. Another invasive ant, the Little Fire Ant, Wasmannia auropunctata (Roger, 1863), showed a significant increase after the mowing. While not as destructive as S. invicta, W.auropunctata has been documented to be a significant pest to many terrestrial vertebrates and should be considered a potential threat in future gopher tortoise and land management schemes.

The Deepwater Horizon oil spill in 2010 prompted an enormous survey effort to assess the under-studied, deep-ocean ecosystems of the Gulf of Mexico. The resulting samples and datasets afforded a unique opportunity to study the ecology of a poorly known group of mesopelagic fishes, the barracudinas (Aulopiformes: Paralepididae). Here we address several important data gaps regarding the ecology of the Paralepididae. Our results indicate that a majority of barracudina species are efficient at...
Show moreThe Deepwater Horizon oil spill in 2010 prompted an enormous survey effort to assess the under-studied, deep-ocean ecosystems of the Gulf of Mexico. The resulting samples and datasets afforded a unique opportunity to study the ecology of a poorly known group of mesopelagic fishes, the barracudinas (Aulopiformes: Paralepididae). Here we address several important data gaps regarding the ecology of the Paralepididae. Our results indicate that a majority of barracudina species are efficient at avoiding research-sized nets, suggesting that their overall abundance has been historically underestimated. Notable differences in vertical distribution, seasonal abundances of sizes classes, and diets were observed among the three major sub-groups of the family, with potential implications to ecosystem-based management of deep-pelagic fisheries. This thesis is dedicated to all the fish, squids, and shrimps that gave their lives to make these data and to those that endured the hardship of the Deepwater Horizon oil spill.
