Climate change interacts with and can often amplify the negative impacts of invasive species. These interactions are not fully appreciated or understood. They can result in threats to critical ecosystem functions on which our food system and other essential provisions and services depend as well as increase threats to human health. The Invasive Species Advisory Committee to the National Invasive Species Council recognizes the Administration’s commitment to dealing proactively with global climate change. However, unless we recognize and act on the impact of climate change and its interaction with ecosystems and invasive species, we will fall further behind in …
Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone
Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone
Department of Environmental Studies: Undergraduate Student Theses
The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …

Dairy production in south-western Australia occurs predominantly on sandy soils in the greater than 800 mm annual average rainfall areas of the region. The climate is Mediterranean-type, typically with cool, wet May-October growing seasons and hot, dry November-April. Most dairy pastures are rain-fed and comprise the annual species Subterranean Clover (clover, Trifolium subterraneum L.), Annual Ryegrass (Lolium rigidum Gaud.) and Italian Ryegrass (L. multiflorum Lam.).
Paddock grown pasture is the cheapest source of feed for dairy production in the region (Dilley and Howes 1998). To remain profitable in the face of diminishing returns, dairy farmers have modified their grazing management …

Four Aspects Of Dogwood Pollination: Insect Visitation, A Novel Approach To Identify Pollen, Floral Volatile Emission, And Tracking Parentage, Paul Raymond Rhoades
Masters Theses
Part 1: Visitation of potential pollinators to Cornus florida and C. kousa flowers was assessed in East Tennessee in 2008 and 2009. Data regarding insect visitation rates to multiple trees per location were gathered throughout the flowering period. Diurnal and seasonal variations in visitation were recorded. Pollen coverage was assessed on portions of captured insect exoskeletons that were most likely to contact the stigma. Eleven families in four insect orders were collected from C. florida and 26 families in five orders from C. kousa. The most important pollinators in eastern Tennessee were bees in the Andrenidae and Halictidae. The most …

BACKGROUND
Invasive species are second only to habitat destruction as the greatest cause of species endangerment and global biodiversity loss. Invasive species can cause severe and permanent damage to the ecosystems they invade. Consequences of invasion include competition with or predation upon native species, hybridization, carrying or supporting harmful pathogens and parasites that may affect wildlife and human health, disturbing ecosystem function through alteration of food webs and nutrient recycling rates, acting as ecosystem engineers and altering habitat structure, and degradation of the aesthetic quality of our natural resources. In many cases we may not fully know the native animals …

Comparative Performance Of Fluorometry And High Performance Liquid Chromatography In The Detection Of Aflatoxin M1 In Two Commercial Cheeses, Gustavo Peña
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Aflatoxin M1 (AFM1) is frequently found in milk and dairy products. It is a metabolite formed in cows from aflatoxin B1 (AFB1), contained in animal feeds. In cheese production AFM1 distributes between curds and whey. In this study, cows were fed 64 µg/AFB1/d for the high treatment, and 5 µg/AFB1/d for the low treatment, to obtain milk contaminated with AFM1 over the 0.5 µg/L and under 0.05 µg/L restrictions, respectively. Cheese was manufactured with milk contaminated with AFM1 at 0.8 and 0.03 ìg/kg by the higher and lower …

Mangrove species are uniquely adapted to tropical and subtropical coasts, and although relatively low in number of species, mangrove forests provide at least US $1.6 billion each year in ecosystem services and support coastal livelihoods worldwide. Globally, mangrove areas are declining rapidly as they are cleared for coastal development and aquaculture and logged for timber and fuel production. Little is known about the effects of mangrove area loss on individual mangrove species and local or regional populations. To address this gap, species-specific information on global distribution, population status, life history traits, and major threats were compiled for each of the …

Role Of Clover "Down On The Farm", Don Sorrell
Role Of Clover "Down On The Farm", Don Sorrell
Forage Symposium at the Kentucky Cattlemen’s Convention
In an effort to evaluate the Role of Clover ”Down on the Farm”, a survey was developed and then e-mailed to Agriculture and Natural Resources Extension Agents in Kentucky. Agents were asked to complete the survey based on their estimate of use and importance of clover in their particular county. Thirtytwo (32) surveys were returned. The following is a summary of those returned surveys.

Establishing Clovers In Pasture And Hay Fields, Garry D. Lacefield
Forage Symposium at the Kentucky Cattlemen’s Convention
Pasture renovation means to renew and improve. In Kentucky, this usually means adding lime and fertilizer, controlling weeds and insects and planting a legume such as red clover and/or white clover. The primary benefits come as a result of getting legumes established in grass-dominated fields.
Estimating Clover Percentage In Your Pasture, S. Ray Smith
Estimating Clover Percentage In Your Pasture, S. Ray Smith
Forage Symposium at the Kentucky Cattlemen’s Convention
You often hear Extension Agents and Extension Specialists talk about how important it is to add clover to your grass pastures. We talk about the advantage of free nitrogen, the added forage quality and yield, the benefit of diluting the toxic effects of tall fescue, and many other benefits. Usually after I give a presentation promoting all the benefits of clover the first question from the audience is, “How much clover do I need?” My standard answer is that 30 to 40% clover provides many of these benefits without compromising grass productivity. In fact, 30 to 40% clover in a …

Why Grow Clovers?, Don Ball, Garry D. Lacefield
Forage Symposium at the Kentucky Cattlemen’s Convention
Clovers have long been viewed as being special and beneficial pasture plants, but recently the incentives livestock producers have to grow them have further increased. Why are many people more interested than ever in growing clovers in pastures as companion species with grasses? Here are several reasons that collectively make a compelling case.

Maria Sibylla Merian's Frogs, Kay Etheridge
Biology Faculty Publications
Maria Sibylla Merian (German, 1647-1717) is best known for her magnificent 1705 publication, Metamorphosis insectorum surinamensium, although she published earlier works on insect metamorphosis. Merian wrote the text and painted all of the illustrations for her books, and for the early volumes she produced most of the engravings. Contemporary scholarship has focused primarily on Merian's detailed images of lepidopteran and host plant life cycles, but Merian's Surinam album also portrays anuram metamorphosis, including the first European depiction of Pipa pipa.

Assessing the potential for threatened species to persist and spread within fragmented landscapes requires the identification of core areas that can sustain resident populations and dispersal corridors that can link these core areas with isolated patches of remnant habitat. We developed a set of GIS tools, simulation methods, and network analysis procedures to assess potential landscape connectivity for the Delmarva fox squirrel (DFS; Sciurus niger cinereus), an endangered species inhabiting forested areas on the Delmarva Peninsula, USA. Information on the DFS’s life history and dispersal characteristics, together with data on the composition and configuration of land cover on the peninsula, …
