Examination Of The Allee Effect On Postlarval Recruitment And Post Settlement Survival In The Caribbean Spiny Lobster Panulirus Argus, Adrianna Zito
Examination Of The Allee Effect On Postlarval Recruitment And Post Settlement Survival In The Caribbean Spiny Lobster Panulirus Argus, Adrianna Zito
All Theses
Positive density dependence (the Allee effect) has been reported in a number of species that are attracted to conspecific cues. This effect has been shown to influence the settlement of many species of marine invertebrates. Caribbean spiny lobsters are gregarious den dwellers attracted to conspecific cues. Previous studies have suggested that the benefit of conspecific attraction is a reduced predation risk by decreasing the time to find crevice shelters (the guide effect) or by cooperative group defense once sharing shelters. I tested a third hypothesis that attraction to conspecific cues increases the settlement of lobster postlarvae into the highest quality …
Subcutaneous Fsh Implants, Colette Floyd
Subcutaneous Fsh Implants, Colette Floyd
All Theses
Superovulation is an assisted reproductive technique used to hyperstimulate the ovaries in an attempt to proliferate desirable genetics by increasing the number of dominant follicles and oocytes available per estrous cycle. Unfortunately, the process is inefficient and costly due to FSH injection protocols, labor requirements, and animal stress. A sustained release implant as a novel FSH delivery mechanism could increase the efficiency and utility while reducing cost and animal stress. The objectives of these experiments were: to design and fabricate a sustained FSH release implant and evaluate the amount of FSH released in-vitro and in-vivo.

Feeding Performance In Hawaiian Stream Goby Fishes: Morphological And Functional Analysis, Takashi Maie
Feeding Performance In Hawaiian Stream Goby Fishes: Morphological And Functional Analysis, Takashi Maie
All Theses
Distributions of Hawaiian stream fishes are typically interrupted by waterfalls that divide streams into lower and upper segments. Larvae hatched upstream are flushed into the ocean, and must climb these waterfalls to reach adult habitats when returning back to freshwater as part of an amphidromous life cycle. Stream surveys and studies of climbing performance show that Lentipes concolor can reach fast-flowing upper stream segments, but that Awaous guamensis reaches only slower, lower stream segments. Gut content analyses for these two species indicate that diet differs between them only by 10% or less dry weight for most major components (mostly green …
Thrombocyte Response To Lipopolysaccharide In Stress Induced Broiler Chicks, Farzana Ferdous
Thrombocyte Response To Lipopolysaccharide In Stress Induced Broiler Chicks, Farzana Ferdous
All Theses
The role of thrombocytes, nucleated blood leukocytes, on immune responses in chickens fed diets supplemented with vitamin C has not been studied in the past. This study investigates the effects of three types of diets(control, control with corticosterone, and control with corticosterone and vitamin C) in 14-day old broiler chicks on the expression of pro-inflammatory cytokines IL-1beta, IL-6, and IL-12 in thrombocytes. In addition, the effect of LPS, a microbial component to which broiler chicks can be exposed, on the expression of these pro-inflammatory cytokines was investigated. After two weeks of feeding, blood samples from the chicks were collected and …
The Proliferative Response Of Equine Chondrocytes To Bovine Lymph Node Proteins In Vitro , Alison Reed
The Proliferative Response Of Equine Chondrocytes To Bovine Lymph Node Proteins In Vitro , Alison Reed
All Theses
Osteoarthritis is a leading cause of chronic lameness in horses. Many treatment options for osteoarthritis have limited effectiveness and are expensive. Treatments that stimulate cartilage development may promote cartilage healing. Bovine supramammary lymph nodes are available at no cost and contain bioactive growth factors that could promote cartilage healing. The purpose of this study was to measure the proliferative response of equine chondrocytes to bovine lymph node proteins. Chondrocytes were harvested from adult horses. Lymph node extract (LNE) was prepared by mixing freeze-dried lymph node powder with PBS. Experiments compared BGS and LNE on equal and unequal protein bases. Additional …
Age, Growth, And Fecundity Of Alabama Shad (Alosa Alabamae) In The Apalachicola River, Florida , Travis Ingram
Age, Growth, And Fecundity Of Alabama Shad (Alosa Alabamae) In The Apalachicola River, Florida , Travis Ingram
All Theses
Age and growth of Alabama shad Alosa Alabamae were estimated by examining scales and otoliths from 203 adult fish collected on their spawning run in the upper Apalachicola River from 2005 and 2006. Ages of Alabama shad ranged from 1 - 4 years. Scales and otoliths both gave similar age estimates. Age distributions from this study differed from those of previous studies for both males and females. Female Alabama shad, on average, were found to be larger than males at age 2 and age 3. Alabama shad demonstrated a positive correlation of length to fecundity, with fecundity estimates ranging from …

In this study, I investigated the potential for temperature to serve as a mechanism for maintenance of reproductive isolation in a sympatric population of Atlantic and Gulf striped bass in the Apalachicola and Ochlockonee rivers, Florida. Adult striped bass (n= 66, mean weight = 8.3 kg, mean total length = 780.6 mm) were collected from February to May below Jim Woodruff Lock and Dam, on the Apalachicola River, and below Jackson Bluff Lock on the Ochlockonee River, Florida. Ancestry (Gulf or Atlantic) of specimens was determined based upon the methods of Wirgin et al. (2005) using three diagnostic microsatellite loci: …
Population Size And Passage Efficiency Of Alabama Shad Reaching Jim Woodruff Lock And Dam, Patrick Ely
Population Size And Passage Efficiency Of Alabama Shad Reaching Jim Woodruff Lock And Dam, Patrick Ely
All Theses
In this study, I estimated the population size of migrating Alabama shad below Jim Woodruff Lock and Dam (JWLD) in the Apalachicola River located in the central panhandle of Northwest Florida using mark recapture and relative abundance techniques. The number of marked fish was adjusted for tag loss, emigration and mortality. The population size of migrating Alabama shad near JWLD was estimated at 26,029 (95% C.I. = 15,174 - 49,040) in 2005 and as 972 (95% C.I. = 270 - 9,720) in 2006. Due to the small sample size, a relative abundance method was used to independently estimate a population …
Influence Of Supramammary Lymph Node Extract On Cell Growth In Vitro, Danelle Duffy
Influence Of Supramammary Lymph Node Extract On Cell Growth In Vitro, Danelle Duffy
All Theses
ABSTRACT The bovine supramammary lymph node, located on the dorso-caudal surface of the udder, is a protein rich organ that is discarded on a regular basis during slaughter. Experiments were conducted to evaluate whether or not the lymph node extract could be used as a substitute for bovine growth serum in cell media. Two different preparations of lymph node extract were made and tested. Three different cell lines (MDA-MB-435, MAC-T, and 1C6) were used in assays to evaluate the lymph node extract as a supplement. The first extract yielded a protein concentration of 3.0 mg/ml (heat inactivated) and the second …
