Trophodynamics Of The Fish Valenciennellus Tripunctulatus. I. Vertical Distribution, Diet And Feeding Chronology, Thomas L. Hopkins, Ronald C. Baird
Trophodynamics Of The Fish Valenciennellus Tripunctulatus. I. Vertical Distribution, Diet And Feeding Chronology, Thomas L. Hopkins, Ronald C. Baird
Marine Science Faculty Publications
The adult and juvenile life stages of the small (~25mm) zooplanktivorous mesopelagic fish Valenciennellus tripunctulatus (Esmark) are found at depths of 200-600m throughout the diel period. Average population density was estimated to be 5 fish (104m3)-1 and the maximum density recorded was 11 fish (104m3)-1. Copepods constituted ~95% of all food items identified and Pleuromamma was the principal forage genus, contributing 31% and 56% to numbers and biomass of food items, respectively. Ontogenetic changes in diet were observed, the percentage of larger copepods increasing in the diet with increasing fish size. Food items …
Continuous Flow Nutrient Bioassays With Natural Phytoplankton Populations Collected In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers
Continuous Flow Nutrient Bioassays With Natural Phytoplankton Populations Collected In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers
Reports
The enclosure system chosen for these experiments was continuous and similar to one described by Jones, Tett, Wallis, and Wood (1978a sn b). They successfully maintained for 41 days in the laboratory, with reasonable constant diversity, a natural phytoplankton community from a Scottish Sea-loch.

Final Report Of The Hillsborough Bay Water Quality Monitoring Program, City Of Tampa Department Of Sanitary Sewers
Reports
The report presented here is the final communication of data collected during the first year and a half of plant operation at variance standards. In addition, earlier data collected by the City of Tampa are also presented in this report in order to give background information of conditions existing prior to operation under the variance (Appendix C). The earlier data may also describe long term trends and normal seasonal cycles occurring in the bay.
The Geology And Hydrogeology Of The Sistema Purification Area, Villa Hidalgo, Tamaulipas, Mexico, Louise D. Hose
The Geology And Hydrogeology Of The Sistema Purification Area, Villa Hidalgo, Tamaulipas, Mexico, Louise D. Hose
KIP Theses and Dissertations
Sistema Purificación, a large cave system in the northern Sierra Madre Oriental of northeastern Mexico, is developed in the Tamaulipas and Tamabra Formations, a sequence of middle Cretaceous carbonates about 400 meters thick. The formations formed in a basinal to periplatform environment near the Platforma Valles-San Luis Potosí, a large carbonate platform simultaneously developing to the south and southwest. The Tamaulipas Formation is strategically underlain by shaly limestone, shale, sandstone, and conglomerate of the Early Cretaceous Taraises, the Late Jurassic La Caja, and the Late Jurassic La Joya Formations.
