Historical Responses Of Marine Turtles To Global Climate Change And Juvenile Loggerhead Recruitment In Florida
Marine turtle conservation is most successful when it is based on sound data incorporating life history, historical population stability, and gene flow among populations. This research attempts to provide that information through two studies. In chapter I, I identify historical patterns of gene …

Applying the principles of spatial modelling to the management of biodiversity in the fragmented landscapes of south-western Australia
Biodiversity conservation throughout the world is challenged by the impacts of a changing climate on fragmented landscapes. To mitigate these threats, conservation managers require models which can demonstrate the consequences of both negative impacts and management actions. This need can be …

Using instream stationary antennas to monitor the movements of warm water fishes in a reach of stream bisected by a culvert
… of movement observed in this study suggest that conservation managers should consider movements of 150m as a potentially frequent weekly occurrence for the species monitored, and other closely related fishes. This study demonstrates the potential long-term impact a culvert can have on the natural …
