Invasion Genetics Of The Non-Native Geckos Phelsuma Grandis Gray 1870 And Gekko Gecko (Linnaeus 1758) In Southern Florida, Usa, Thomas William Fieldsend

Biological invasions cause tremendous damage to ecosystems, economies, and human livelihoods worldwide. Florida is home to more established non-native species of reptiles and amphibians than anywhere else on Earth, many of which cause substantial harm to native biodiversity and human well-being. The relatively new discipline of invasion genetics promises to significantly improve the understanding, prediction, prevention, and management of biological invasions. The purpose of this dissertation is to utilize invasion genetics techniques to further understanding of the patterns and processes of biological invasions, especially as they pertain to Florida’s destructive and diverse non-native squamate reptile assemblage. In the first phase …
Investigating Sub-Tropical Community Resistance And Resilience To Climate Disturbance, Ross E. Boucek
Investigating Sub-Tropical Community Resistance And Resilience To Climate Disturbance, Ross E. Boucek
FIU Electronic Theses and Dissertations
Changes in global climate will likely increase climate variability. In turn, changes in climate variability have begun to alter the frequency, intensity, and timing of climate disturbances. Continued changes in the climate disturbance regime experienced by natural systems will undoubtedly affect ecological processes at every hierarchical scale. Thus, in order to predict the dynamics of ecological systems in the future, we must develop a more mechanistic understanding of how and in what ways climate disturbance affects natural systems. In South Florida, two climate disturbances recently affected the region, a severe cold spell in 2010, and a drought in 2011. Importantly, …
The Interactive Effects Of Predators, Resources, And Disturbance On Freshwater Snail Populations From The Everglades, Clifton B. Ruehl
The Interactive Effects Of Predators, Resources, And Disturbance On Freshwater Snail Populations From The Everglades, Clifton B. Ruehl
FIU Electronic Theses and Dissertations
The origins of population dynamics depend on interplay between abiotic and biotic factors; the relative importance of each changing across space and time. Predation is a central feature of ecological communities that removes individuals (consumption) and alters prey traits (non-consumptive). Resource quality mitigates non-consumptive predator effects by stimulating growth and reproduction. Disturbance resets predator-prey interactions by removing both. I integrate experiments, time-series analysis, and performance trials to examine the relative importance of these on the population dynamics of a snail species by studying a variety of their traits. A review of ninety-three published articles revealed that snail abundance was much …
