Reproductive Health And Performance Of The Florida Flock Of Introduced Whooping Cranes, Marilyn G. Spalding, Martin J. Folk, Stephen A. Nesbitt, Richard Kiltie Jan 2010

Reproductive Health And Performance Of The Florida Flock Of Introduced Whooping Cranes, Marilyn G. Spalding, Martin J. Folk, Stephen A. Nesbitt, Richard Kiltie

Proceedings of the North American Crane Workshop

We retrospectively examined the reproductive parameters of 122 breeding-age whooping cranes (Grus americana) in a reintroduced flock in central Florida from 1992 to 2007. The flock performed poorly when compared with an existing wild flock for all reproductive parameters when controlled for age. Pairs first formed in 1995, nested in 1999, and the first chick fledged in 2002. By 2007, 19 of 63 clutches produced 25 chicks, 9 of which fledged. Drought conditions were ruled out as the sole cause of failure when the drought lessened and productivity increased, but not in all years. We examined adult health, …

A Retrospective Of Whooping Cranes In Captivity, Cindi Barrett, Thomas V. Stehn Jan 2010

A Retrospective Of Whooping Cranes In Captivity, Cindi Barrett, Thomas V. Stehn

Proceedings of the North American Crane Workshop

Early records of captive whooping cranes (Grus americana) were compiled from historical files kept at the Aransas National Wildlife Refuge and other literature. Additional early records of captive whooping cranes in Europe were discovered. Annual numbers and location for all captive whooping cranes were tabulated. Starting in 1949, initial attempts at breeding the species in captivity were conducted opportunistically with a few injured birds captured from the wild. Acaptive breeding flock was started in 1966 at the Patuxent Wildlife Research Center in Laurel, Maryland, from second eggs collected in Canada from the only remaining wild flock. In 1989, the flock …

Changes In Winter Whooping Crane Territories And Range 1950–2006, Thomas V. Stehn, Felipe Prieto

Proceedings of the North American Crane Workshop

The whooping crane (Grus americana) winters on the Texas coast primarily in salt marsh habitat. The location of adult whooping crane winter territories during 9 winters between 1950 and 2006 was derived from aerial census data digitized onto infrared photos using GIS software. Range expansion, including changes in distribution and size of winter territories, was analyzed over a 57-year period as flock size increased by 765%. Crane pairs have opted to establish territories in or close to the traditional winter area rather than moving long distances along the coast. This distribution seems based on the preference of the …

Habitat Selection Of Eastern Migratory Whooping Cranes On Their Wintering Grounds, Lara E. A. Fondow, Stanley A. Temple Jan 2010

Habitat Selection Of Eastern Migratory Whooping Cranes On Their Wintering Grounds, Lara E. A. Fondow, Stanley A. Temple

Proceedings of the North American Crane Workshop

As a monitoring technician for the Whooping Crane Eastern Partnership, I (LEAF) noted that birds in years following release selected wintering habitats that differed greatly from those into which they were initially released. An analysis of the habitat preferences of these birds was needed in order to determine any possible implications to the reintroduction efforts. During the winters of 2004-2005 and 2005-2006, I recorded the locations, habitat use, social associations, and behaviors of all migratory whooping cranes (Grus americana) at known locations in Florida. I used compositional analysis to determine whether habitat use was random at the following …

Design, Development And Biomechanical Analysis Of Scaffolds For Augmentation Of Rotator Cuff Repairs, Amit Aurora

ETD Archive

Rotator cuff tears are a source of debilitating pain that commonly affects more than 40 of our aging population. Despite advances in surgical treatment, the failure rate of rotator cuff repairs is as high as 20-90 . Extracellular matrix (ECM) derived scaffolds have recently been investigated as augmentation devices for rotator cuff repairs, but none has yet demonstrated both the appropriate biological and mechanical properties for mitigating re-tears and enhancing healing. This dissertation proposes to engineer the mechanical properties of allograft fascia lata in a manner that will allow its use as an augmentation device for rotator cuff repairs. This …

The Role Of Ceruloplasmin In Colitis, Bakytzhan Bakhautdin Jan 2010

The Role Of Ceruloplasmin In Colitis, Bakytzhan Bakhautdin

ETD Archive

Ceruloplasmin (Cp) is an acute phase, plasma protein with multiple enzymatic activities consistent with both pro- and anti-inflammatory functions. Our laboratory has recently reported the presence of Cp in intestinal epithelial cells. To determine the potential role of Cp in intestinal inflammation, we induced colitis in Cp-deficient mice by continuous administration of dextran sodium sulfate (DSS) ad libitum in the drinking water. The Cp-null mice rapidly lost weight and all were moribund by day 14, while about 90 of the wild-type (WT) mice survived at least 20 days. Higher amounts of TNF-alpha, and neutrophil (KC) and macrophage (MCP-1) chemokines, were …

The Role Of Sigirr In Innate And Adaptive Immunity, Muhammet Fatih Gulen

ETD Archive

Single immunoglobulin IL-1R-related receptor (SIGIRR) is a transmembrane protein, which belongs to interleukin 1 receptor (IL-1R)/Toll like receptor (TLR) superfamily (Toll-IL-1R superfamily). SIGIRR has been identified as a negative modulator for IL-1R/TLR signaling. Recently, detailed structural and functional analysis of SIGIRR has been published, however physiological function of SIGIRR has not been studied. To asses the physiological function of SIGIRR, the expression of SIGIRR mRNA in different mouse tissues was analyzed. Although SIGIRR is expressed in many tissues, its expression in different cell types was more restricted, with extremely high expression in primary kidney, colon epithelial cells and T cells, …

Interactions Among Top-Down Regulators In A Temperate Forest Floor Ecosystem;Effects On Macrofauna, Mesofauna, Microbes And Litter Decay, Cari-Ann M. Hickerson

ETD Archive

High species diversity and complexity of forest-floor food webs present a challenge for understanding the role of species interactions (e.g. competition and predation) as regulatory mechanisms for ecosystem processes such as decomposition and nutrient cycling. In particular, we understand very little about the roles of forest-floor predators in regulating diversity and abundance of lower trophic levels and ecosystem processes. However, ecological theory and several studies suggest that interactions among intraguild predators (IGP) may be important controls of diversity and abundance of organisms and detritus in lower trophic levels within food webs. A key prediction is that interactions among predators weaken …

An Assessment Of The Evolutionary Stability Of Distyly In Hedyotis Caerulea (Rubiaceae), Dennis Archie Sampson Jan 2010

An Assessment Of The Evolutionary Stability Of Distyly In Hedyotis Caerulea (Rubiaceae), Dennis Archie Sampson

ETD Archive

Distylous species of flowers possess two distinct floral morphs that are generally found in equal numbers in naturally occurring populations. The flower form that has a relatively long style is called a "pin" the form with a short style is a "thrum." Within the distylous mating system, selfing and intramorph mating are prevented due to the spatial separation of stigmas and anthers and by a self-incompatibility system that is inherited along with the dimorphic floral structure and ancillary polymorphisms. However, a breakdown of distyly has been documented in several families, either through the development of completely separate sexes (dioecy), or, …

To Reframe A Constitution: Public Service In A Consumptive State, Steven T. Salmi Jan 2010

To Reframe A Constitution: Public Service In A Consumptive State, Steven T. Salmi

ETD Archive

This normative analysis builds upon Ulrich Beck's world risk society theory to argue that the United States is making a shift of revolutionary proportions from an administrative state to a consumptive state. Public administration theory is assessed for its ability to address a consumptive state's unprecedented dynamics, e.g., accelerating technoscientific development and mega-hazards such as global warming. Qualitative evidence suggests that the field's adaptability has been limited by a continued, if generally unacknowledged, embrace of obsolete normative commitments such as to a politics-technoscience dichotomy, contempocentrism, and overconsumption. The sustainability movement, a discourse coalition with roots largely outside public administration, is …

Cell-Taught Gene Therapy For The Preservation And Regeneration Of Cardiac Tissue Following Chronic Heart Failure, Srividya Sundararaman Jan 2010

Cell-Taught Gene Therapy For The Preservation And Regeneration Of Cardiac Tissue Following Chronic Heart Failure, Srividya Sundararaman

ETD Archive

Heart failure is the primary cause of mortality and morbidity in the Western world. Although cell therapy has demonstrated improvement in cardiac function, these benefits are being attributed to the activation of paracrine factors, rather than the differentiation and integration of the transplanted cells into the host tissue. Based on this knowledge the focus of this thesis work was to deliver paracrine factors, and evaluate its effect on cardiac function. Gene therapy has evolved as a promising option to deliver pro-angiogenic proteins to infarct zones, thus providing cardiac benefit. This study has identified a gene design without the use of …

Suicide Pelicans, Amanda A. Mccoy Jan 2010

Suicide Pelicans, Amanda A. Mccoy

ETD Archive

The suicide pelican lives in Costa Rica. You may not believe me, but I've seen it with my own eyes. Blindness is common for these birds, mostly caused by their form of fishing: dive-bombing into the water at full speed and spearing fish with their beaks. This head-first diving damages the eyes over the years. Once blind, some of the pelicans intentionally crash into rocks to avoid an unbearable, unnatural existence. These birds and their surprisingly beautiful, graceful suicide plunges influenced this collection of short stories aptly titled Suicide Pelicans. Though my collection is mostly about women and not actual …

Targets Of Hsa-Mir-488* In Human Prostate Carcinoma Cells, Jinani E. Slaibi

ETD Archive

Prostate cancer (PCa) is one of the most prevalent forms of cancer among men in America and is second only to lung cancer as a cause of cancer-related deaths in men. Recent epidemiological study shows that one in every six men over the age of forty five is at risk of PCa. Androgen receptor (AR) plays a causative role in the development of PCa. Hormonal blockade therapy which inhibits the expression of AR eventually fails and disease progresses to fatal androgen-refractory stage from androgen-dependent stage. Therefore, novel molecular approaches which can target and block the expression of AR are required. …

A Theoretical Model Of The Effect Of Bone Defects On Anterior Shoulder Instability: A Finite Element Approach, Piyush Walia Jan 2010

A Theoretical Model Of The Effect Of Bone Defects On Anterior Shoulder Instability: A Finite Element Approach, Piyush Walia

ETD Archive

Presence of either a Hill Sachs or a Bony Bankart lesion has been indicated as a possible cause of subluxation and anterior shoulder dislocation. Previous studies have investigated only effects of these isolated lesions on the glenohumeral instability of the shoulder. The purpose of this thesis was to investigate the effect of both Bony Bankart lesion and Hill-Sachs lesion in the glenohumeral joint on the stability of the shoulder. We hypothesize that as the size of the lesion increases, the glenohumeral joint's stability will decrease. We further hypothesize that the presence of both defects together will reduce the glenohumeral joint's …
