Quantifying The Association Between Active Tuberculosis Incidence And Migrant Farm Worker Populations Among Florida Counties, 2009-2013: An Ecological Study, Ryan Nicolas Ortega Mar 2016

Quantifying The Association Between Active Tuberculosis Incidence And Migrant Farm Worker Populations Among Florida Counties, 2009-2013: An Ecological Study, Ryan Nicolas Ortega

USF Tampa Graduate Theses and Dissertations

Nearly 20 studies conducted in the last 40 years indicate that tuberculosis (TB) represents a major health concern among migrant farm worker (MFW) populations, but their role in the transmission of TB within the broader community is poorly understood. To this end an ecological study was undertaken which examined 67 Florida counties between years 2009 through 2013. Its aims were as follows: (1) to describe the demographic, geographic, and temporal distribution of the incidence of active TB, (2) to examine the effect of agriculturally relevant seasonal periods on the incidence of active TB, and (3) to quantify the strength and …


The Entrance As A Complex Ecotone In A Neotropical Cave, Xavier Prous, Rodrigo Lopes Ferreira, Claudia Maria Jacobi Feb 2015

The Entrance As A Complex Ecotone In A Neotropical Cave, Xavier Prous, Rodrigo Lopes Ferreira, Claudia Maria Jacobi

International Journal of Speleology

Cave entrances are transition zones with intermediate characteristics between epigean environments, which bear lower environmental stability, and hypogean environments, with lower food resources. Associated to these interfaces there is a specific community, capable of exploiting its unique and intermediate characteristics. This work investigated this community in a Brazilian limnestone cave, identifying its arthropod species composition and spatial distribution, and exploring its relationships with climatic and structural environment characteristics and trophic relations. An ecotone zone was identified, with 55 species found only in the ecotone, 49 species were shared with the epigean community, 37 species with the hypogean community, and 14 …

The Big Watermelon: A Cultural History Of Florida's Brooksville Ridge, Douglas E. Ponticos Jan 2013

The Big Watermelon: A Cultural History Of Florida's Brooksville Ridge, Douglas E. Ponticos

USF St. Petersburg campus Master's Theses (Graduate)

The Brooksville Ridge has long been the dominant cultural landscape of westcentral Florida. Though rarely used as a cultural designation today, the region’s landscapes continue to unify a people. More than simply an environmental or geologic region, the Brooksville Ridge was born in a period of colonialism and exuberant extraction for distant markets. Before the Ridge, west-central Florida landscapes, such as Amasura and Withlacoochee, were defined predominantly by local and regional needs. This thesis uses a number of primary and secondary documents to trace the changing cultural landscapes of west-central Florida, from pre-Columbian and Seminole landscapes to the rise of …
