Utilizing Ecological Niche Modelling To Predict Habitat Suitability Of Eastern Equine Encephalitis In Florida, Claire Burch, Rebecca Loraamm, Thomas R. Unnasch, Joni A. Downs
Utilizing Ecological Niche Modelling To Predict Habitat Suitability Of Eastern Equine Encephalitis In Florida, Claire Burch, Rebecca Loraamm, Thomas R. Unnasch, Joni A. Downs
School of Geosciences Faculty and Staff Publications
Eastern Equine Encephalitis virus (EEEV) is a virus found predominantly east of the Mississippi River in the United States that can be fatal to both equines and humans. The disease has previously been most prolific in states like Florida, but there has been an increase in the prevalence in other states further up north on the east coast of the United States in recent years. The purpose of this research is to use the ecological niche modelling program Maxent to model EEEV habitat suitability probability. This research utilized data of fatality incidence in equine hosts, versus sentinel chicken infection data, …
Did Shell-Crushing Crabs Trigger An Escalatory Arms Race In The Aftermath Of A Late Neogene Regional Mass Extinction Event? An Experimental Test, Lisa B. Whitenack, Gregory S. Herbert
Did Shell-Crushing Crabs Trigger An Escalatory Arms Race In The Aftermath Of A Late Neogene Regional Mass Extinction Event? An Experimental Test, Lisa B. Whitenack, Gregory S. Herbert
School of Geosciences Faculty and Staff Publications
A regional mass extinction event in the late Neogene western Atlantic is widely thought to have generated evolutionary opportunities for survivors, including enemy-related adaptation (escalation). The Strombus alatus species complex is one potential example of this phenomenon. Strombid gastropods are abundant in the Plio-Pleistocene fossil record and Recent in subtropical Florida, and the percentage of these shells bearing a row of short spines on the last whorl increased from nearly zero to almost 100% over this time. As shell ornamentation is one of the most frequently cited defenses against both peeling and crushing predators, we exposed live spined and spineless …

The Bay Study Group was created by the City of Tampa in 1976 to monitor the effects of pollution abatement that occurred in Hillsborough Bay when the city’s wastewater treatment plant was upgraded from primary to advanced treatment in 1979. The Bay Study Group documented a remarkable restoration of water quality parameters and biological indicators in Hillsborough Bay from the mid 1980s until 2009, when it was disbanded. This zip Geodatabase file contains the aerial photos for the year 2010.

Variable Intensity Of Teleconnections During The Late Holocene In Subtropical North America From An Isotopic Study Of Speleothem From Florida, Philip E. Van Beynen, Yemane Asmerom, Victor J. Polyak, Limaris R. Soto, Jason S. Polk
Variable Intensity Of Teleconnections During The Late Holocene In Subtropical North America From An Isotopic Study Of Speleothem From Florida, Philip E. Van Beynen, Yemane Asmerom, Victor J. Polyak, Limaris R. Soto, Jason S. Polk
School of Geosciences Faculty and Staff Publications
The persistence and influence of both tropical and extra‐tropical teleconnections on the hydrology of subtropical North America are little understood. Major atmospheric‐oceanic controls on the isotopic composition of the precipitation reconstructed from a 1,000 year old stalagmite are the North Atlantic Oscillation (NAO) and the Pacific Decadal Oscillation (PDO). These teleconnections create decadal‐ to centennial‐scale changes in the seasonal distribution of precipitation. An increase in the winter proportion of annual precipitation coincides with negative phase NAO conditions and a positive phase PDO. However, the PDO's influence appears to be weakened when it is out of phase with the El Niño …
