Extreme environmental events (EEEs) are likely to exert deleterious effects on populations. From 1996 to 2012 we studied the nesting dynamics of a riverine population of painted turtles (Chrysemys picta) that experienced seven years with significantly definable spring floods. We used capture–mark–recapture methods to estimate the relationships between more than 5 m and more than 6 m flood events and population parameters. Contrary to expectations, flooding was not associated with annual differences in survival, recruitment or annual population growth rates of the adult female segment of the population. These findings suggest that female C. pictaexhibit resiliency to ...

Here Be Dragons: Functional Analyses Of Thermal Adaptation And Biogeography Of Reptiles In A Changing World, Rory S. Telemeco

Graduate Theses and Dissertations

Environments around the world are changing rapidly and a major challenge for modern biologists is to understand how these changes affect organisms, communities, and ecosystems. Ideally, we would like to predict which taxa/populations are likely to remain stable, increase, or decline in response to predicted environmental perturbations. This information will allow us to create informed management plans and will provide insight into the ecological and evolutionary processes that shape biodiversity. For my Ph.D. dissertation, I examined factors that mediate the responses of reptile populations to rapid changes in the thermal environment, explored the ability of these factors to ...


Lineage-Specific Transcriptional Profiles Of Symbiodinium Spp. Unaltered By Heat Stress In A Coral Host, Daniel J. Barshis, Jason T. Ladner, Thomas A. Oliver, Stephen R. Palumbi Jan 2014

Lineage-Specific Transcriptional Profiles Of Symbiodinium Spp. Unaltered By Heat Stress In A Coral Host, Daniel J. Barshis, Jason T. Ladner, Thomas A. Oliver, Stephen R. Palumbi

Biological Sciences Faculty Publications

Dinoflagellates of the genus Symbiodinium form an endosymbiosis with reef building corals, in which photosynthetically derived nutrients comprise the majority of the coral energy budget. An extraordinary amount of functional and genetic diversity is contained within the coral-associated Symbiodinium, with some phylotypes (i.e., genotypic groupings), conferring enhanced stress tolerance to host corals. Recent advances in DNA sequencing technologies have enabled transcriptome-wide profiling of the stress response of the cnidarian coral host; however, a comprehensive understanding of the molecular response to stress of coral-associated Symbiodinium, as well as differences among physiologically susceptible and tolerant types, remains largely unexplored. Here, we ...
