Elephants - A Conservation Overview, Heidi Riddle, Bruce A. Schulte, Ajay Desai, Laura Van Der Meer Jan 2010

Elephants - A Conservation Overview, Heidi Riddle, Bruce A. Schulte, Ajay Desai, Laura Van Der Meer

Biology Faculty Publications

Loss of habitat is one of the most significant problems facing elephants worldwide, leading to clashes over resources between wildlife and humans where elephants receive the largest part of blame – defined as Human Elephant Conflict (HEC). The sub-Saharan region of Africa contains an approximate population of 500,000 elephants that occupy 37 range countries. The African Elephant (Loxodonta africana) is categorized as Vulnerable in the Red List of Threatened Species; they are listed there as two distinct subspecies: the Savanna Elephant (L.a. africana) and the Forest Elephant (L. a. cyclotis). The Red List of …

A Simplified Method For Monitoring Progestagens In African Elephants Under Field Conditions, Bruce A. Schulte, Elizaeth Freeman, F. Nicole Abbondanza, Jordana Meyer, Janine Brown Jan 2010

A Simplified Method For Monitoring Progestagens In African Elephants Under Field Conditions, Bruce A. Schulte, Elizaeth Freeman, F. Nicole Abbondanza, Jordana Meyer, Janine Brown

Biology Faculty Publications

Summary: 1. Hormone analyses are frequently used to support management of wildlife; however, current techniques are not very field-friendly. In situ hormone monitoring is often expensive, time consuming and logistically difficult. Thus, a new method for assessing ovarian cycle activity non-invasively in free-ranging African elephants was developed. 2. The technique involves handshaking faecal samples in common organic solvents, use of environmentally stable antibody-coated microtitre plates and assessment of progestagen concentrations based on a visual colour change. 3. Studies using ex situ African elephants determined that handshaking faeces in a solution of isopropyl alcohol was effective for extracting the faecal progestagens …

Investigating Instructors' Conceptions Of Evolution Through The Development Of The Classroom Test Of Evolutionary Reasoning, Patricia Eileen Palko Jan 2010

Investigating Instructors' Conceptions Of Evolution Through The Development Of The Classroom Test Of Evolutionary Reasoning, Patricia Eileen Palko

Electronic Theses and Dissertations

In order to assess the evolutionary understanding of high school biology teachers, an instrument entitled the Classroom Test of Evolutionary Reasoning (CTER) was developed. Content, response process, relations to another variable (the Conceptual Inventory of Natural Selection, or CINS), and internal structure evidence were compiled. The second version of the CTER was found to have adequate reliability and validity estimates to allow it to continue to be used as a measurement tool for an understanding of evolution. When assessing a sample of teachers (n = 724), the mean score was 6.35 out of a possible 13 points. The sample was …

Neuronal Calcium Regulation And Cellular Stress In A Malignant Hyperthermia Disease Model, Jason Santiago Jan 2010

Neuronal Calcium Regulation And Cellular Stress In A Malignant Hyperthermia Disease Model, Jason Santiago

Electronic Theses and Dissertations

Calcium ions (Ca2+) are essential signaling molecules and must be carefully regulated to preserve specificity in function. One indispensible Ca2+ signaling protein is the ryanodine receptor (RyR) calcium release channel. RyR1 is essential for muscle contraction, and RyR1mutations can lead to severe muscle disorders such as malignant hyperthermia (MH). Recently, a mouse model of human MH (Y522S-RyR1) has been developed. In skeletal muscle, Y522S-RyR1 exhibits an increased sensitivity to activation resulting in Ca2+ leak, mitochondrial disorganization, and cellular stress. Although RyR1 expression is limited in the brain, the cerebellum may be particularly vulnerable to this disease because RyR1 is highly …

The Proteomic Response Of The Mussel Congeners Mytilus Gallaprovincialis And M. Trossulus To Acute Heat Stress: Implications For Thermal Tolerance Limits And Metabolic Costs Of Thermal Stress, Lars Tomanek, Marcus J. Zuzow Jan 2010

The Proteomic Response Of The Mussel Congeners Mytilus Gallaprovincialis And M. Trossulus To Acute Heat Stress: Implications For Thermal Tolerance Limits And Metabolic Costs Of Thermal Stress, Lars Tomanek, Marcus J. Zuzow

Biological Sciences

The Mediterranean blue mussel, Mytilus galloprovincialis, an invasive species in California, has displaced the more heat-sensitive native congener, Mytilus trossulus, from its former southern range, possibly due to climate change. By comparing the response of their proteomes to acute heat stress we sought to identify responses common to both species as well as differences that account for greater heat tolerance in the invasive. Mussels were acclimated to 13°C for four weeks and exposed to acute heat stress (24°C, 28°C and 32°C) for 1 h and returned to 13°C to recover for 24 h. Using two-dimensional gel electrophoresis and …

Zooplankton Avoidance Of A Profiled Open-Path Fluorometer, Kelly J. Benoit-Bird, Mark A. Moline, Oscar M. Schofield, Ian C. Robbins, Chad M. Waluk Jan 2010

Zooplankton Avoidance Of A Profiled Open-Path Fluorometer, Kelly J. Benoit-Bird, Mark A. Moline, Oscar M. Schofield, Ian C. Robbins, Chad M. Waluk

Biological Sciences

Significant avoidance of acoustically detected zooplankton was observed in response to a profiling instrument package. Avoidance decreased acoustic scattering from zooplankton averaged over the entire profile by more than a factor of 2, while the maximum avoidance decreased zooplankton acoustic scattering by a factor of 15 over the depth of some discrete scattering layers. Experimental manipulation of the profiler and its instruments revealed that an open-path fluorometer was triggering the avoidance. Avoidance occurred at an average of 8 m below the profiler with a range between 2 and 13 m. Effect range was positively correlated with the average attenuation coefficient …

Genome Size Is A Strong Predictor Of Root Meristem Growth Rate, Adam Gruner, Nathan Hoverter, Tylia Smith, Charles A. Knight Jan 2010

Genome Size Is A Strong Predictor Of Root Meristem Growth Rate, Adam Gruner, Nathan Hoverter, Tylia Smith, Charles A. Knight

Biological Sciences

Variation in genome size (GS) has been linked to several facets of the plant phenotype. Recently it was shown that GS is significantly correlated with cell size and the duration of the cell cycle. Here we test the hypothesis that GS might also be a predictor of apical root meristem growth rate (RMGR). We studied eight species of eudicots with varying GS using time-lapse microscopic image analysis. A significant negative exponential relationship was observed between GS and RMGR. Our results show significantly decreased RMGR for large genome species. This relationship represents a significant consequence of GS expansion in plants and …

Extracellular Matrix Of The Charophycean Green Algae, Sarah Nelson Kiemle Jan 2010

Extracellular Matrix Of The Charophycean Green Algae, Sarah Nelson Kiemle

Dissertations, Master's Theses and Master's Reports - Open

A comprehensive knowledge of cell wallstructure and function throughout the plant kingdom is essential to understanding cell wall evolution. The fundamental understanding of the charophycean green algal cell wall is broadening. The similarities and differences that exist between land plant and algal cell walls provide opportunities to understand plant evolution. A variety of polymers previously associated with higher plants were discovered in the charophycean green algae (CGA), including homogalacturonans, cross-linking glycans, arabinogalactan protein, β-glucans, and cellulose. The cellulose content of CGA cell walls ranged from 6% to 43%, with the higher valuescomparable to that found in the primary cell wall …

Catalog Of The Coreidae, Or Leaf-Footed Bugs, Of The New World, Richard J. Packauskas Jan 2010

Catalog Of The Coreidae, Or Leaf-Footed Bugs, Of The New World, Richard J. Packauskas

Fort Hays Studies Series

Studies on the New World Coreidae have languished for more than a century. Neglect of these often large, abundant, and occasionally economically important bugs has been due, I believe, to the lack of means to identify them. Most literature treating the New World Coreidae has been restricted to the North American fauna, except for the recent efforts of Brailovsky (1975 to 2007).

The Influence Of Sexual Selection On Behavioral And Physiological Mechanisms Underlying Reproductive Success In Male Cape Ground Squirrels (Xerus Inauris), Mary Beth Manjerovic Jan 2010

The Influence Of Sexual Selection On Behavioral And Physiological Mechanisms Underlying Reproductive Success In Male Cape Ground Squirrels (Xerus Inauris), Mary Beth Manjerovic

Electronic Theses and Dissertations

Sexual selection is considered a powerful evolutionary force responsible for the enormous diversity found in reproductive morphology, physiology, and behavior. I addressed questions related to selection in the Cape ground squirrel (Xerus inauris), a species characterized as highly social and promiscuous. These attributes often are responsible for variance in male reproductive success and as such, sexual selection theory predicts increased opportunity for sexual selection. I confirm that the predominant mechanism underlying genital evolution and competition for paternity in X. inauris is sperm competition. I find evidence that investment in sperm competition is costly and may reflect immunocompetence. I quantify reproductive …

Biological Sciences Faculty Research & Creative Works

Coal and gold mining are important economic activities in New Zealand, and the West Coast of the South Island and Southland, for example, have long histories of mining. The process of mineral extraction inevitably results in environmental impacts, but few tools exist to help mining companies and regulators assess and predict environmental impacts of mining operations. This framework has been developed as part of a collaborative research programme with key mining partners to assist with planning of future mine developments on the West Coast and in Southland. This framework focuses on water quality issues associated with coal and gold mining, …

Receptor-Dependent Phagocytosis Of Clostridium Sordellii By Human Decidual Macrophages, Tennille D. Thelen Jan 2010

Receptor-Dependent Phagocytosis Of Clostridium Sordellii By Human Decidual Macrophages, Tennille D. Thelen

Master's Theses and Doctoral Dissertations

Clostridium sordellii is an emerging pathogen associated with highly-lethal female reproductive tract (FRT) infections following childbirth, abortion, or cervical instrumentation. Gaps in our understanding of the pathogenesis of C. sordellii infections present major challenges to the development of better preventive and therapeutic strategies against this problem. We sought to determine the mechanisms whereby uterine DMs phagocytose this bacterium and tested the hypothesis that human DMs utilize class A scavenger receptors (CASRs) to internalize unopsonized C. sordellii. In vitro phagocytosis assays with human DMs incubated with pharmacological inhibitors of CASRs (fucoidan, polyinosinic acid, and dextran sulfate) revealed a role for …

Faculty Publications, Biological Sciences

Background Sooty (Puffinus griseus) and short-tailed (P. tenuirostris) shearwaters are abundant seabirds that range widely across global oceans. Understanding the foraging ecology of these species in the Southern Ocean is important for monitoring and ecosystem conservation and management. Methodology/Principal Findings Tracking data from sooty and short-tailed shearwaters from three regions of New Zealand and Australia were combined with at-sea observations of shearwaters in the Southern Ocean, physical oceanography, near-surface copepod distributions, pelagic trawl data, and synoptic near-surface winds. Shearwaters from all three regions foraged in the Polar Front zone, and showed particular overlap in the region around 140°E. Short-tailed shearwaters …

Niche Partitioning Among And Within Sympatric Tropical Seabirds Revealed By Stable Isotope Analysis, H S. Young, D J. Mccauley, R Dirzo, R D. Dunbar, Scott A. Shaffer Jan 2010

Niche Partitioning Among And Within Sympatric Tropical Seabirds Revealed By Stable Isotope Analysis, H S. Young, D J. Mccauley, R Dirzo, R D. Dunbar, Scott A. Shaffer

Faculty Publications, Biological Sciences

The low productivity and unpredictable nature of resources in tropical waters would appear to make resource partitioning among predators difficult. Yet, stable isotope data from the present study suggest that substantial resource partitioning occurs among tropical seabird communities, both between and within species. In the present study, we compared δ13C and δ15N levels among 8 sympatric tropical seabird species. For a subset of these species, we also examined isotopic levels across years, breeding periods, and sexes. When breeding and non-breeding periods were both considered, we found that all species occupied distinct isotopic niches across at least one time period. Resource …

Batrachochytrium Dendrobatidis Detected In Amphibians From National Forests In Eastern Texas, Usa, Daniel Saenz, Brendan T. Kavanagh, Matthew Kwiatkowski

Faculty Publications

The amphibian disease chytridiomycosis, caused by the pathogenic fungus Batrachochytrium dendrobatidis (Bd, Longcore et al. 1999), is well known as a major threat to amphibians resulting in mass die-offs and population declines throughout the world (Berger et al. 1998; Blaustein and Keisecker 2002; Daszak et al. 2003; McCallum 2005; Rachowicz et al. 2006). Batrachochytrium dendrobatidis has been detected on amphibians from sites across North America (Ouellet et al. 2005; Woodhams et al. 2008) and appears to be most prevalent in the western and the northeastern United States (Longcore et al. 2007; Schlaepfer et al. 2007). Whereas infected anurans also have …

Faculty Publications

We isolated and characterized 16 microsatellite loci from the Louisiana pine snake, Pituophis ruthveni. Loci were screened in 24 individuals from locations throughout its distribution in Louisiana and Texas. The number of alleles per locus ranged from 4 to 12, observed heterozygosity ranged from 0.200 to 0.875, and the probability of identity ranged from 0.043 to 0.298. We examined cross-species amplification at these loci in P. catenifer (bullsnakes and gopher snakes) and P. melanoleucus (pine snakes). These new markers provide tools for examining the conservation genetics of this species complex. Louisiana pine snakes face numerous threats: population densities are extremely …

Liana Host Preference And Implications For Deciduous Forest Regeneration, Laura M. Ladwig, Scott J. Meiners Jan 2010

Liana Host Preference And Implications For Deciduous Forest Regeneration, Laura M. Ladwig, Scott J. Meiners

Faculty Research & Creative Activity

Lianas have the potential to shape forest communities and alter forest regeneration. However, impacts of lianas on forest regeneration, particularly in temperate forests, are largely unstudied. To understand potential liana impacts on the community we need to first know the location and intensity of liana burdens on host trees. We examined liana-tree host references within a series of young regenerating deciduous forests in the Piedmont region of New Jersey, USA. Established trees ($ 5 cm dbh) and the lianas associated with each tree were surveyed in 2008. The five most abundant liana species were Celastrus orbiculatus, Lonicera japonica, Parthenocissus quinquefolia, …

Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, Laura Ladwig, Scott J. Meiners Jan 2010

Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, Laura Ladwig, Scott J. Meiners

Faculty Research & Creative Activity

Although they are important components of forest communities, the general ecology and spatiotemporal patterns of temperate lianas during forest regeneration are largely unknown. The dependence of lianas on other plants for physical support makes them a potentially important driver of community dynamics. We examined 50 years of vegetation data from an old-field succession study to determine the dynamics and community controls on liana expansion within the Piedmont region of New Jersey, USA. Four lianas, Lonicera japonica, Parthenocissus quinquefolia, Toxicodendron radicans, and Vitis spp., occurred in enough abundance for detailed analyses. In general, liana cover peaked during mid-succession (20–30 years post-abandonment) …

Allelopathic Effects Of Goldenrod Species On Turnover In Successional Communities, Nikki Pisula, Scott J. Meiners Jan 2010

Allelopathic Effects Of Goldenrod Species On Turnover In Successional Communities, Nikki Pisula, Scott J. Meiners

Faculty Research & Creative Activity

While goldenrod species are often found to be allelopathic in laboratory settings, its importance in controlling plant community dynamics has been much more difficult to assess. We designed a study to determine whether allelopathy is related to the success of goldenrods in abandoned agricultural land. To accomplish this, we conducted laboratory bioassays for six co-occurring goldenrod species and compared these results to the cover and impacts of these species in the field. We determined the germination responses of two target species to a gradient of leaf extract concentrations to assess the allelopathic potential of these goldenrods. We also used long-term …

A Sketch-Based Language For Representing Uncertainty In The Locations Of Origin Of Herbarium Specimens, Barry J. Kronenfeld, Andrew Weeks Jan 2010

A Sketch-Based Language For Representing Uncertainty In The Locations Of Origin Of Herbarium Specimens, Barry J. Kronenfeld, Andrew Weeks

Faculty Research and Creative Activity

Uncertainty fields have been suggested as an appropriate model for retrospective georeferencing of herbarium specimens. Previous work has focused only on automated data capture methods, but techniques for manual data specification may be able to harness human spatial cognition skills to quickly interpret complex spatial propositions. This paper develops a formal modeling language by which location uncertainty fields can be derived from manually sketched features. The language consists of low-level specification of critical probability isolines from which a surface can be uniquely derived, and high-level specification of features and predicates from which low-level isolines can be derived. In a case …
