Spawning Chronology Of Native And Introduced Striped Bass (Morone Saxatilis) In Two Gulf Of Mexico Drainages, Matthew Noad

All Theses

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: …

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 …

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

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 …

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 …

A Comparison Of Pyronin Y-Methyl Green Stain And Methylene Blue Stain For Somatic Cell Count In Sheep Milk, Emily Mirek, Stacey O’Donnell

Senior Honors Projects

Somatic cell count is a key method used to evaluate the quality of milk in today’s growing dairy sheep industry. Somatic cells are body cells, primarily the white blood cells, found in a milk sample. If an infection such as mastitis is present, the number of somatic cells in the milk increases (Gonzalo, et al. 1992). Producers routinely perform somatic cell counts on cow and goat milk. For dairy cattle in the United States, the somatic cell count can not exceed 750,000 cells per milliliter, for commercial milk. For dairy goats the accepted limit is 1,000,000 cells per mL of …

Importance Of Early Successional Forest For Wildlife In Southern New England, Amy Wynia

Senior Honors Projects

Many bird species that require early successional forest are declining in the Northeast U.S. because such habitat is relatively rare and when they inhabit the more common mature forests or suburban areas they are less successful. Early successional forest is maintained by regular disturbance (wind, fire, clear-cutting, and flooding) which has been happening less frequently during the past 50 years. Bird species that have declined during this time and which inhabit early successional forest include ruffed grouse (Bonasa umbellus), blue jay (Cyanocitta cristata), chestnut-sided warbler (Dendroica pensylvanica), gray catbird (Dumetella carolinensis), field sparrow (Spizella pusilla), golden-winged warbler (Vermivora chrysoptera), eastern …

Mechanics Of Suction Generation During Feeding In Little Skates, Danielle Duquette

Senior Honors Projects

Feeding mechanisms of aquatic vertebrates has been extensively studied in the past, while that of elasmobranchs remains limited. Skates and rays are believed to have evolved from a shark ancestor, thus they represent the most derived group. All skates are dorsoventrally compressed, have a unique jaw suspension type and head skeleton and live in benthic environments. It is unknown whether these derived features of skates have altered the ancestral shark feeding mechanism. Comparing feeding mechanisms in skates and sharks may shed light on morphological transformations that have arisen after the evolutionary split of these two groups. In this study prey …

The Public Perception Of Enrichment For Captive Animals, Elizabeth Marie Webb

All Master's Theses

The effects of providing participants with educational information on enrichment as measured by the looking time at and ratings of zoo photographs were examined. One hundred and seventeen participants viewed photographs of zoo exhibits, 10 from each of the following categories: artificial exhibit with artificial enrichment, artificial exhibit with naturalistic enrichment, naturalistic exhibit with naturalistic enrichment, and naturalistic exhibit with artificial enrichment. Participants rated the photographs on exhibit aesthetic appeal, perceived animal happiness, and effectiveness of the enrichment. Pre- and posttest ratings of the importance of zoo roles were also collected. Results showed support for the hypothesis that participants provided …

Fecundity And Survival Of The Calanoid Copepod Acartia Tonsa Fed Isochrysis Galeana (Tahitian Strain) And Chaetoceros Mulleri, Angelos Apeitos

Master's Theses

Historically, red snapper (Lutjanus campechanus) larviculture at the Gulf Coast Research Lab (GCRL) used 25 ppt artificial salt water and mixed, wild zooplankton composed primarily of Acartia tonsa, a calanoid copepod. Acartia tonsa was collected from the estuarine waters of Davis Bayou and bloomed in outdoor tanks from which it was harvested and fed to red snapper larvae. We are developing a more controlled copepod mass culture system to support finfish larviculture. To that end, I examined the effect of single species versus mixed species of algae as food for the copepods. Wild A. tonsa were isolated and reared in …

Clouded Leopard Phylogeny Revisited: Support For Species Recognition And Population Division Between Borneo And Sumatra, Andreas Wilting, Valerie A. Buckley-Beason, Heike Feldhaar, Jurgen Gadau, Stephen J. O'Brien, K. Eduard Linsenmair

Biology Faculty Articles

Background

The clouded leopard (Neofelis nebulosa) is one of the least known cat species and depletion of their forested habitats puts it under heavy pressure. Recently reclassification of Bornean clouded leopards (N. nebulosa diardi) to species level (N.diardi) was suggested based on molecular and morphological evidence. Since the genetic results were based solely on three Bornean samples we re-evaluated this partition using additional samples of Bornean clouded leopards (N = 7) and we were also able to include specimens from Sumatra (N = 3), which were lacking in previous analysis.

Results

We found strong …

Identification And Control Of Pest Slugs And Snails For Broadacre Crops In Western Australia, Svetlana Micic, Ken Henry, Paul Horne

Bulletins 4000 -

The numbers of slugs and snails have increased in broadacre cropping in Western Australia with the use of minimum tillage and stubble-retention practices. The organic content of paddocks increases under such systems, providing an increased food source especially to young slugs and snails. Soil moisture content is greater over summer leading to higher survival levels of slugs and snails.

Slug and snail pests in Australia have come from other countries, mainly the Mediterranean region. They damage plant seeds (mainly legumes), recently germinated seeds, seedlings and leaves and can be a contaminant of grain at harvest.

Across-Breed Adjustment Factors For Expected Progeny Differences For Carcass Traits, L. Dale Van Vleck, L. V. Cundiff, T. L. Wheeler, S. D. Shackelford, M. Koohmaraie

Department of Animal Science: Faculty Publications

Adjustment factors to allow comparison of EPD from several breed associations for birth, weaning, and yearling weights have been available for more than 10 yr. This paper describes steps to calculate adjustment factors for EPD for 4 carcass traits: marbling score, fat thickness, ribeye area, and retail product percentage. The required information is the same as for the weight traits: 1) breed of sire solutions based on measurements on progeny at the US Meat Animal Research Center (USMARC) that have sires with breed association EPD, 2) mean EPD of sires weighted by number of progeny at USMARC (USMARC progeny not …

Bats Of Saint Martin, French West Indies/Sint Maarten, Netherlands Antilles, Hugh H. Genoways, Scott C. Pedersen, Peter A. Larsen, Gary G. Kwiecinski, Jeffrey J. Huebschman

University of Nebraska State Museum: Mammalogy Papers

Six species of bats have been previously reported from the Antillean island of Saint Martin/Sint Maarten—Artibeus jamaicensis, Brachyphylla cavernarum, Molossus molossus, Tadarida brasiliensis, Noctilio leporinus, and Myotis nigricans nesopolus. Our field research reported herein documents an additional three species of bats from the island for the first time—Monophyllus plethodon, Ardops nichollsi, and Natalus stramineus. Re-examination of the single voucher of Myotis nigricans nesopolus has led us to exclude this species from the fauna of Saint Martin/Sint Maarten. Based on our field research and the study of specimens housed in museum collections, we present information …

Reproductive Cycles Of The Pearl Oysters, Pinctada Fucata (Gould) And Pinctada Margaritifera (Linnaeus) (Bivalvia: Pteriidae) In Southwestern Taiwan Waters, Jiuan-Jiuan Hwang

Journal of Marine Science and Technology–Taiwan

The reproductive cycles of the pearl oysters Pinctada fucata (Gould) and Pinctada margaritifera (Linnaeus) were examined based on 339 and 284 specimens, collected in southwestern Taiwan. Except for the month of December 2002, Pinctada fucata were collected during the periods from March 2002 to September 2003. Pinctada margaritifera were collected over two periods: from March 2002 to November 2002 and from June 2003 to September 2003. Histological observations on gonadal development indicated that Pinctada fucata and Pinctada margaritifera were protandrous hermaphrodites, and both species exhibited different annual cyclical patterns, in which maturity peaked in May and October for Pinctada fucata, …

Objectives of the study were (i) to evaluate the efficiency of the fish traps in catching 0+ and 1+ pink snapper (Pagrus auratus), (ii) to investigate the distribution and abundance of juvenile pink snapper in both gulfs using trap surveys, (iii) to investigate the influence of environmental factors including habitat-type on the distribution of juvenile pink snapper and, (iv) to develop trap indices of 0+ relative abundance and assess their use for monitoring …

A Sustainable Future For Fishing On Christmas Island. A Draft Five-Year Strategy For Managing Commercial, Recreational And Charter Fishing., Department Of Fisheries Western Australia.

Fisheries Management Papers

This draft strategy was developed by the Department of Fisheries, Western Australia, hereafter known as the “Department of Fisheries” which has responsibility for managing fish resources (within Territorial waters out to 12 nautical miles) on behalf of the Commonwealth Department of Transport and Regional Services (DoTARS), through the applied Fish Resources Management Act (FRMA) (WA)(CI) (the “Applied Act”). The Applied Act provides a legislative framework that allows for management arrangements to be developed specifically for Christmas Island. The management of fisheries in Western Australia uses an adaptive approach which balances the need for the effective management of fish stocks with …

Shark Bay Prawn And Scallop Fisheries. Draft Review Report, Department Of Fisheries Western Australia

Fisheries Management Papers

In recent times, the Department of Fisheries has received representations from both sectors about the ongoing interaction of the fisheries and their respective management settings. As a result, a decision was made to comprehensively review the fisheries, taking into account matters of fishery sustainability and gear interactions, together with industry economics and market considerations. The review has also addressed research requirements to ensure an appropriate scientific basis for decision-making into the future.

The Tadpole Of Leptodactylus Notoaktites Heyer, 1978 (Anura, Leptodactylidae), Rafael O. De Sá, José A. Langone, Magno V. Segalla

Biology Faculty Publications

The external morphology and oral disc of the tadpole of Leptodactylus notoaktites Heyer, 1978, are described and illustrated for Gosner’s stage 33. The internal oral anatomy was analyzed under SEM at Gosner’s stage 36 whereas chondrocranial anatomy is reported for Gosner’ stage 38. The morphology of this tadpole is compared with those available for other species of the L. mystaceus complex. The overall characteristics do not depart from those known for the genus Leptodactylus and they particularly agree for those of the fuscus species group. The labial tooth row formula is 2(2)/3.

A Molecular Evaluation Of The North American “Grassland” Sparrow Clade, John Klicka, Garth M. Spellman

Ornithology Program (HRC)

Because they share several morphological and ecological characters, the North American sparrow (Emberizidae) genera Ammodramus, Passerculus, and Xenospiza have historically been considered members of a well-defined “grassland” sparrow assemblage. Relationships among the 11 members of this group have been the subject of much taxonomic debate, yet no comprehensive molecular assessment of relationships has been done. We investigated these relationships using mitochondrial DNA sequence data that included complete cytochrome-b and ND2 genes. Phylogenetic reconstructions derived via parsimony, likelihood, and Bayesian methods were congruent. The grassland sparrows, as presently configured, are polyphyletic. Pooecetes gramineus, Amphispiza belli (but not A. …

Extensions Of Local Domains With Trivial Generic Fiber, William Heinzer, Christel Rotthaus, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We consider injective local maps from a local domain R to a local domain S such that the generic fiber of the inclusion map R -> S is trivial, that is P R (0) for every nonzero prime ideal P of S. We present several examples of injective local maps involving power series that have or fail to have this property. For an extension R -> S having this property, we give some results on the dimension of S; in some cases we show dim S = 2 and in some cases dim S = 1.

A Survey Of The Cockle A. Antiquata, Chumbe Island, Kelsey Jacobsen, Lisl Esherick

Independent Study Project (ISP) Collection

A survey of the cockle Anadara antiquata’s population was performed on the intertidal zone of Chumbe, a small island located off of Zanzibar, Tanzania. Cockle abundance and size were measured along transects laid parallel to shore at four sites, two sites on the west side and two on the east. The marine and intertidal environments on the western side of the island are protected under Chumbe Island Coral Park (CHICOP), a privately managed Marine Protected Area (MPA). However, small-scale artisanal fisheries including cockle collection by women still occur on the unprotected east side. This study will attempt to evaluate the …
