A Study Of The Eastern Oyster, Crassostrea Virginica, In Tampa Bay: Effects Of Perkinsus Marinus On Reproduction And Condition, Bridgit Melora Mccrickard

USF Tampa Graduate Theses and Dissertations

Abstract

Five sites in Tampa Bay, Florida, were sampled monthly from February 2006 to January 2007. These sites were located at the mouth of the Alafia River, in an inlet of Cross Bayou, on the easement of Gandy Bridge, near mangrove in Manatee County, and an inlet of Salt Creek, off Bayboro Harbor. Standard methods were used to determine shell height and Condition Index (CI). Intensity and prevalence of Perkinsus marinus were analyzed using Ray's Thioglycollate medium test, while Haplosporidium nelsoni was studied by histological examination. Histological methods were also used to determine sex ratios, reproductive phases, and egg diameters. …

Optimal Body Size With Respect To Maximal Speed For The Yellow-Spotted Monitor Lizard (Varanus Panoptes; Varanidae), Christofer J. Clemente, Philip C. Withers, Graham Thompson

Research outputs 2012

Studies of locomotor performance often link variation in morphology with ecology. While maximum sprint speed is a commonly used performance variable, the absolute limits for this performance trait are not completely understood. Absolute maximal speed has often been shown to increase linearly with body size, but several comparative studies covering a large range of body sizes suggest that maximal speed does not increase indefinitely with body mass but rather reaches an optimum after which speed declines. Because of the comparative nature of these studies, it is difficult to determine whether this decrease is due to biomechanical constraints on maximal speed …

Investigation Of The Histological Development Of The Frontal Ganglion In Locusta Migratoria L. 1758 (Orthoptera, Acrididae), Meltem Kumaş, Hati̇ce Karaki̇şi̇

Turkish Journal of Zoology

The frontal ganglion plays a critical role in insect feeding and molting-related behaviors. It is present in all insect orders at all developmental stages. In this study, the histological development of the frontal ganglion of Locusta migratoria, the African migratory locust, was investigated. Ganglia were dissected at 3 distinct developmental stages and their histological structure was evaluated at the light microscope level. The development of the cells generating the ganglion in the first and fifth nymphal stages and in adults was determined using the variance analysis method. Total width and length of the ganglion cells as well as width and …
