Aspects Of The Life History Of The Snowy Grouper, Epinephelus Niveatus, In The Gulf Of Mexico, Kelley Kowal
Aspects Of The Life History Of The Snowy Grouper, Epinephelus Niveatus, In The Gulf Of Mexico, Kelley Kowal
USF Tampa Graduate Theses and Dissertations
Knowledge of many life history parameters are essential to properly assess and manage fish species. Although the snowy grouper, Epinephelus niveatus, is a commercially valuable fish, which is harvested throughout the Gulf of Mexico, little is known about its age, growth, and reproduction from this region. In this study, snowy grouper from the northern and eastern regions of the Gulf of Mexico were examined primarily using commercially-derived samples that were collected between 1984 and 2004. A total of 1,200 snowy grouper with fork lengths between 242 and 1,190 mm were collected. Sectioned saggital otoliths were used to determine the age …
Discovery Of Novel Viruses From Animals, Plants, And Insect Vectors Using Viral Metagenomics, Terry Fei Fan Ng
Discovery Of Novel Viruses From Animals, Plants, And Insect Vectors Using Viral Metagenomics, Terry Fei Fan Ng
USF Tampa Graduate Theses and Dissertations
Understanding emerging viruses is critical for disease monitoring and prediction; however, surveys of novel viruses are hindered by the lack of a universal assay for viruses. Viral metagenomics, consisting of viral particle purification and shotgun sequencing, is a powerful technique for discovering viruses in a wide variety of sample types. However, current protocols are not effective on tissue samples (e.g., lungs, livers and tumors), where they are hindered by the high amount of host nucleic acids which limits the percentage of sequences that originate from viruses. In this dissertation, a modified viral metagenomics protocol was developed and utilized to effectively …
Linking Soil Loss To Sediment Delivery In Two Estuaries In Puerto Rico, Nekesha Bernadette Williams
Linking Soil Loss To Sediment Delivery In Two Estuaries In Puerto Rico, Nekesha Bernadette Williams
USF Tampa Graduate Theses and Dissertations
Enhanced soil loss from the watershed is a major environmental issue. Increased soil loss from a watershed can potentially increase sediment delivery and loading to aquatic ecosystems such as rivers and estuaries. An increase in sediment delivery and loading to freshwater and transitional marine ecosystems can impact water quality and supply specifically by: (1) reducing water clarity, (2) transporting nutrient and pollutant laden sediments and (3) reducing the storage capacity of reservoirs. To address these broader environmental impacts of increased sediment delivery and loading to aquatic ecosystems it is imperative that potential source areas of sediments available for transport are …
