Exploring Epigenetics As A Tool For Population Assessment And Conservation In Large Marine Predators, Andria Paige Beal

FIU Electronic Theses and Dissertations

Worldwide, many large marine predator populations are in decline. These populations can be difficult to study due to the extensive home ranges and migration patterns often exhibited by these species. Molecular tools are therefore necessary to measure specific parameters on these populations that would otherwise be nearly impossible to obtain. This dissertation pioneers the use of environmental epigenetic approaches for that purpose, and specifically the epigenetic modification known as DNA methylation, using sharks and small cetaceans as model organisms. This work is organized into five chapters. Chapter I is an introductory chapter that lays out the fundamentals of environmental epigenetics …

Epigenetic Mechanisms As Drivers Of Environmental Responses In Stony Corals, Javier A. Rodriguez Casariego

FIU Electronic Theses and Dissertations

The current pace of anthropogenic global change is imposing unprecedented conditions to biological systems. Coral reef ecosystems are particularly sensitive to the rapid increase in thermal anomalies and the changes in water chemistry caused by global change. However, although their decline has been documented worldwide, there are signs suggesting that stony corals harbor greater phenotypic plasticity than previously expected, sparking the interest in the study acquired non-genetic modifications (e.g., epigenome, microbiome) potentially increasing their resilience to global change, and constituting one of the main targets for intervention.

Epigenetics constitutes an exciting frontier to understand how the environment influences the regulation …
