Developing Strategy And Tools For The Local Elimination Of Multiple Pest Species, Graham Nugent, David R. Morgan, Peter Sweetapple, Bruce Warburton Aug 2007

Developing Strategy And Tools For The Local Elimination Of Multiple Pest Species, Graham Nugent, David R. Morgan, Peter Sweetapple, Bruce Warburton

Managing Vertebrate Invasive Species

Control of invasive vertebrate pests is likely to be needed in perpetuity unless their pest status changes or they are completely eradicated, both of which seem unlikely at present. This emphasizes the need for pest managers to adopt long-term strategies that are both ecologically sound and cost-effective. We suggest that a strategy for simultaneous management of multiple sympatric species of pests is preferable to a single-species approach. While present strategy involves periodic control over entire areas to achieve management aims, modelling suggests that a strategy of localised elimination followed by perimeter control offers significant cost-savings in the long term. We …

Tree Squirrels As Invasive Species: Conservation And Management Implications, Geoffrey H. Palmer, John Koprowski, Tony Pernas Aug 2007

Tree Squirrels As Invasive Species: Conservation And Management Implications, Geoffrey H. Palmer, John Koprowski, Tony Pernas

Managing Vertebrate Invasive Species

The impact of invasive species on native biodiversity is increasing worldwide. Mammalian invaders are formidable ecological and economic threats, and tree squirrels are models of such challenges. We review the worldwide distribution of tree squirrel introductions and detail their nearly universal success. The biological characteristics of tree squirrels that enable success as invasive species are: high reproductive potential, high vagility, diverse food habits, ability to construct nests, and plasticity in human-impacted landscapes. We document costs and benefits of tree squirrel introductions, and discuss existing management strategies planned for some species. We focus on an introduced population of Mexican red-bellied squirrels …

An Evaluation Of Passive Thermal Fumigation For Brown Treesnake Control In Surface Transportation From Guam, Gad Perry, Daniel S. Vice Aug 2007

An Evaluation Of Passive Thermal Fumigation For Brown Treesnake Control In Surface Transportation From Guam, Gad Perry, Daniel S. Vice

Managing Vertebrate Invasive Species

The brown treesnake (BTS) has been on Guam for about 50 years and in this period has caused extensive ecological, economic, and social damage. It has also repeatedly dispersed from Guam via the transportation network, arriving at numerous locations. However, the conditions snakes face in surface shipping are unknown, making assessment of the risk of snake survival impossible. To address this, we recorded thermal conditions in surface shipments leaving Guam and identified factors that determine these conditions. We monitored 16 shipments to locations in Micronesia and the United States mainland and conducted a series of intensive studies at the Naval …

Environmental And Economic Costs Of Vertebrate Species Invasions Into The United States, David Pimental Aug 2007

Environmental And Economic Costs Of Vertebrate Species Invasions Into The United States, David Pimental

Managing Vertebrate Invasive Species

The more than 50,000 species of plants, animals, and microbes introduced into the United States (US) cause more extinction of native species than most any other threat and cause more than $120 billion in damages and control costs each year. In particular, invasive mammals and birds cause major environmental and economic losses totaling about $46 billion per year in damage and control costs per year. Feral cats, rats, and hogs are especially serious pests. Pigeons and starlings are a major concern in cities and US agriculture. Prevention and management strategies will be discussed.

Impacts Of Introduced Species On An Island Ecosystem: Non-Native Reptiles And Amphibians In The Us Virgin Islands, Renata J. Platenberg Aug 2007

Impacts Of Introduced Species On An Island Ecosystem: Non-Native Reptiles And Amphibians In The Us Virgin Islands, Renata J. Platenberg

Managing Vertebrate Invasive Species

Island ecosystems are highly sensitive to the impacts of introduced species. Non-native invasive snakes, lizards, and amphibians can introduce diseases into native populations and have other deleterious effects through predation, competition, and habitat manipulation. The United States (US) Virgin Islands are situated on the Puerto Rican Shelf in the Caribbean Sea and have a long history of human impacts and species introductions. Two species, the green iguana (Iguana iguana) and the red-legged tortoise (Geochelone carbonaria) were historically introduced and have become naturalized with little apparent impact to the local ecosystem. Recent years, however, have seen the …

Habitattitude™: Getting A Backbone About The Pet Release Pathway, Jamie K. Reaser, N. Marshall Meyers Aug 2007

Habitattitude™: Getting A Backbone About The Pet Release Pathway, Jamie K. Reaser, N. Marshall Meyers

Managing Vertebrate Invasive Species

Many people would not consider their family complete without a pet. Unfortunately, for some pet owners, circumstances arise that prevent them from being able to properly care for their companions and pet abandonment has become one of the most common pathways of vertebrate species introduction. It is also one of the most challenging pathways to address once the animals become established, eradication and control programs face significant public scrutiny and are often challenged by “animal rights” groups. Prevention measures are thus the key to minimizing the size and impacts of the “pet release pathway.” Habitattitude™ is a proactive campaign designed …

Population Ecology And Some Potential Impacts Of Emerging Populations Of Exotic Parrots, Douglas E. Runde, Will C. Pitt, J. T. Foster Aug 2007

Population Ecology And Some Potential Impacts Of Emerging Populations Of Exotic Parrots, Douglas E. Runde, Will C. Pitt, J. T. Foster

Managing Vertebrate Invasive Species

Parrots have been transported around the world since the 1400s and about 44 species have established populations outside of their native ranges. At least 70% of these introduced species were identified as potential agricultural pests, compared to only 15% of all parrot species. At least 74 exotic psittacines have been reported in the wild in the United States, but only nine species were considered established. Since 1990, 24 psittacine species have been sighted in the wild in Hawai`i, about 21 species regularly occur on the main islands and at least five appear established. Past history of successful introduction, recent status …

Early Detection And Eradication Of Invading Rats, James C. Russell, Mick N. Clout, David R. Towns Aug 2007

Early Detection And Eradication Of Invading Rats, James C. Russell, Mick N. Clout, David R. Towns

Managing Vertebrate Invasive Species

Invasive rats continue to colonize rat-free islands around the world. To prevent rats from establishing on rat-free islands, especially following their eradication, biosecurity actions are required to enable early detection and elimination. Rats arrive at islands by both human transportation and by swimming. There are very little data on the rates of rat transportation by humans, although it is known that they are not negligible. There are better data on the distances rats can swim, allowing estimates to be made of the risk of reinvasion of islands close to source populations. Biosecurity prioritization must take place across all rat-free islands, …

Dna Detection Of Foxes To Prevent Establishment In Tasmania, Stephen D. Sarre, Rachel Walsch, Niccy Aitken, Alison Foster, Nick Mooney Aug 2007

Dna Detection Of Foxes To Prevent Establishment In Tasmania, Stephen D. Sarre, Rachel Walsch, Niccy Aitken, Alison Foster, Nick Mooney

Managing Vertebrate Invasive Species

The red fox (Vulpes vulpes) has wreaked havoc on mainland Australia’s environment and agricultural production since its introduction in the 1870s. Over the same period, the southern Australian island State of Tasmania has remained virtually fox-free, allowing its unique biodiversity to remain relatively pristine. Recently, an unknown number of foxes were deliberately or accidentally introduced to Tasmania. Some of those animals and possibly their progeny now live in the wild in Tasmania. Finding foxes in a state the size of Tasmania presents special problems for wildlife managers, but is essential to prevent their establishment in this stronghold for …

Flotation Materials For Aerial Delivery Of Acetaminophen Toxic Baits To Brown Treesnakes, Peter J. Savarie, Tom C. Mathies, Kathleen A. Fagerstone Aug 2007

Flotation Materials For Aerial Delivery Of Acetaminophen Toxic Baits To Brown Treesnakes, Peter J. Savarie, Tom C. Mathies, Kathleen A. Fagerstone

Managing Vertebrate Invasive Species

Polyvinyl chloride (PVC) tubes are effective bait stations for delivering dead neonatal mice (DNM) treated with the oral toxicant, 80 mg acetaminophen, to brown treesnakes (Boiga irregularis) in accessible jungle forest on Guam. However, PVC tubes are not practical for delivery of baits to remote areas of jungle or the forest canopy. Further, it is important that baits entangle in the canopy and not fall to the ground where they can be scavenged by non-target animals such as crabs. Data from helicopter aerial deployment of untreated DNM with radio transmitters that landed on the ground in areas of …

Coqui Frog Research And Management Efforts In Hawaii, Hans Sin, Adam Radford Aug 2007

Coqui Frog Research And Management Efforts In Hawaii, Hans Sin, Adam Radford

Managing Vertebrate Invasive Species

ī The coqui frog (Eleutherodactylus coqui) is native to Puerto Rico and was accidentally introduced to the State of Hawai‘i through contaminated nursery products from the Caribbean. Since its introduction in the late 1980s, coqui have become widely dispersed and in some areas population densities have reached 55,000 frogs/ha. The coqui frog is a species of concern because individual frogs can produce sound levels of 80 decibels (at 0.5 m), which has caused sleep loss to residents and affected the quality of life in Hawai‘i. Economic concerns in infested areas include diminished property values and sales, impacts on …

Pest Eradication Technology – The Critical Partner To Pest Exclusion Technology: The Maungatautari Experience, Cam Speedy, Tim Day, John Innes Aug 2007

Pest Eradication Technology – The Critical Partner To Pest Exclusion Technology: The Maungatautari Experience, Cam Speedy, Tim Day, John Innes

Managing Vertebrate Invasive Species

Invasive pest eradication is an increasingly viable management option for conservation and wildlife managers all over the world. The list of successful rodent eradications from isolated islands continues to grow globally. Now, with the development of effective pest exclusion technologies, the opportunities for eradicating multiple species of vertebrate pests from progressively larger fragments of habitat in mainland situations are also increasing. Attempts at eradicating up to fifteen separate species of pest mammal from indigenous forest fragments protected by Xcluder™ pest proof fencing have been made on the main islands of New Zealand. These include various assemblages of multiple species of …

The Brown Treesnake Rapid Response Team, James W. Stanford, Gordon H. Rodda Aug 2007

The Brown Treesnake Rapid Response Team, James W. Stanford, Gordon H. Rodda

Managing Vertebrate Invasive Species

In the 1940s the brown treesnake (Boiga irregularis) was accidentally transported to Guam and became established. Brown treesnakes have caused and continue to cause major problems for the ecology, economy, and quality of life on Guam. As Guam’s snake densities increased in the late 1970s, extralimital encounters began to be reported on islands with transportation links to Guam. In 1993, a major effort was initiated to reduce the potential for brown treesnakes to accidentally enter Guam’s transportation system. In 2002, a multi-agency Rapid Response Team (RRT) was established to assist in detection and capture of brown treesnakes on …

Monitoring The Sale And Trafficking Of Invasive Vertebrate Species Using Automated Internet Search And Surveillance Tools, Karl Suiter, Sanda Sferrazza Aug 2007

Monitoring The Sale And Trafficking Of Invasive Vertebrate Species Using Automated Internet Search And Surveillance Tools, Karl Suiter, Sanda Sferrazza

Managing Vertebrate Invasive Species

The internet is often an unregulated pathway that can lead to the introduction of invasive species. Surveillance of internet-related sale or trade activities can reduce the movement of potentially invasive species and serve to lessen the risk of an introduction. The Invasive Species Internet Monitoring System automates the process of searching the internet for suspect sites (e.g., internet storefronts, chat rooms, etc.) involved in the sale or trade of targeted species. Additionally, this software system incorporates data management features that permit the archiving of suspect website content, assists subject matter experts in evaluating sites for risk, send informational emails to …

Genetic Options For The Control Of Invasive Vertebrate Pests: Prospects And Constraints, Ronald E. Thresher Aug 2007

Genetic Options For The Control Of Invasive Vertebrate Pests: Prospects And Constraints, Ronald E. Thresher

Managing Vertebrate Invasive Species

Conventional methods for the control of invasive pests are generally effective only on small-space scales or short-time frames. For most well established pest populations, longer-term efforts to manage the problem have been largely abandoned. I examine the potential of using “autocidal” genetic techniques to control terrestrial vertebrate pests, based on the inheritance through males of transgenes that either sterilize females or convert them into functional males (“daughterless”). Simulation analysis of two high profile pest species, the cane toad (Bufo marinus) in Australia and brown rats (Rattus norvegicus) in an urban environment, using realistic parameters, suggests that …

Developing A Decision Support System For Improving Possum Control Planning, Bruce Warburton, Jim Coleman, Mark Fuglestad, James Dietrich Aug 2007

Developing A Decision Support System For Improving Possum Control Planning, Bruce Warburton, Jim Coleman, Mark Fuglestad, James Dietrich

Managing Vertebrate Invasive Species

Brushtail possums are a major invasive pest in New Zealand. A decision support system (DSS) has been developed to enable those involved in operational planning or delivery of possum control to access available relevant knowledge when making operational decisions. The DSS comprises checklists that ensure users consider relevant constraints and issues, a database of best-practice information on possum control, and an “expert” system that recommends actions based on information provided by the user.

Invasive Species: A National Perspective And The Need For A Coordinated Response, Lori Williams Aug 2007

Invasive Species: A National Perspective And The Need For A Coordinated Response, Lori Williams

Managing Vertebrate Invasive Species

The multiple economic, environmental, and animal and human health impacts of invasive species pose complex challenges in policy formation and governmental coordination. The National Invasive Species Council (NISC) was established by an Executive Order in 1999 to provide coordination, planning and facilitate cooperation among the diverse federal agencies and to take a more comprehensive approach to invasive species. NISC, assisted by the nonfederal Invasive Species Advisory Committee (ISAC) has developed several tools and enhanced capacities to address invasive species. Additionally, NISC has helped place greater emphasis on essential prevention, early detection and rapid response, research, public outreach, and international cooperation …

Are There Personality Factors That Can Undermine Moral Judgment Development?, Nathan A. Kerr Aug 2007

Are There Personality Factors That Can Undermine Moral Judgment Development?, Nathan A. Kerr

Masters Theses & Specialist Projects

Research in moral psychology has focused on understanding what factors assist in the development of moral action and decision making. Examples of these research factors include educational experiences (Rest et al, 1986), intelligence (Rest, 1979), and social networking (Derryberry & Thoma, 2000). Personality factors facilitating moral judgment have also receive attention in recent years with Damon and Hart (1988) exploring self-understanding as a possible factor in moral judgment and Baumeister and Exline (1999) proposing that exercising self-control is often characteristic of those who often employ prosocial behavior. Pizarro (2000) suggested that those who fail to utilize empathy may think about …

Influence Of Anxiety On Hiv Testing Behavior, Ilze Nix Aug 2007

Influence Of Anxiety On Hiv Testing Behavior, Ilze Nix

Masters Theses & Specialist Projects

The specter of Human Immunodeficiency Virus (HIV) or Acquired Immune Deficiency Syndrome (AIDS) has become increasingly prevalent since it first entered public awareness in 1982. The Center for Disease Control (CDC) estimates that approximately 1 million people in the United States of America (USA) are living with HIV/ AIDS. More alarming is the fact that approximately 250,000 people remain unaware of their seropositivity status, therefore putting themselves and others at risk. Ignorance concerning HIV status is due largely to two factors: either failure to take an HIV test in the first place, or, a failure to retrieve results after testing. …

Validity Of The Clinical Assessment Of Depression With The Brief Symptom Inventory, Carlie West Aug 2007

Validity Of The Clinical Assessment Of Depression With The Brief Symptom Inventory, Carlie West

Masters Theses & Specialist Projects

Depression is a disorder frequently noted in college students that can affect multiple aspects of one's life, ranging from physical health issues to interpersonal relationship difficulties. Therefore, it is imperative that the depressive symptoms of college students be identified, evaluated, and treated. This investigation explored the validity of a newly published self-report narrow-band measure of depression, the Clinical Assessment of Depression (CAD; Bracken & Howell, 2004) with an existing broad-band measure, the Brief Symptom Inventory (Derogatis, 1993). College students 18 to 52 years of age (n = 280) enrolled in undergraduate courses in psychology at a south central Kentucky university …

Self-Injury In The Schools: A Survey Of School Psychologists, Amy Beld Aug 2007

Self-Injury In The Schools: A Survey Of School Psychologists, Amy Beld

Masters Theses & Specialist Projects

This investigation explores knowledge, training, and practice issues for school psychologists in working with youth who self-injure. Self-injury (SI) is the socially unaccepted, deliberate, self-inflicted harm of an individual's body to reduce psychological distress, without the intention to die as a consequence. As SI is viewed as the "the next teen disorder" (Welsh, 2004), school psychologists are increasingly encountering students who self-injure. Thus, it is necessary to determine school psychologists' ability to respond to youth who self-injure. The purpose of the present study was to conduct a survey of practicing school psychologists to provide information about their knowledge and skills, …

Hiv-2 Rna Dimerization Is Regulated By Intramolecular Interactions In Vitro, Tayyba T. Baig, Jean-Marc Lanchy, J. Stephen Lodmell Aug 2007

Hiv-2 Rna Dimerization Is Regulated By Intramolecular Interactions In Vitro, Tayyba T. Baig, Jean-Marc Lanchy, J. Stephen Lodmell

Biological Sciences Faculty Publications

Genomic RNA dimerization is an essential process in the retroviral replication cycle. In vitro, HIV-2 RNA dimerization is mediated at least in part by direct intermolecular interaction at stem-loop 1 (SL1) within the 5'-untranslated leader region (UTR). RNA dimerization is thought to be regulated via alternate presentation and sequestration of dimerization signals by intramolecular base- pairings. One of the proposed regulatory elements is a palindrome sequence ( pal) located upstream of SL1. To investigate the role of pal in the regulation of HIV-2 dimerization, we randomized this motif and selected in vitro for dimerization- competent and dimerization-impaired RNAs. Energy minimization …

High Rates Of Sulfate Reduction In A Low-Sulfate Hot Spring Microbial Mat Are Driven By A Low Level Of Diversity Of Sulfate-Respiring Microorganisms, Jesse G. Dillon, Susan Fishbain, Scott R. Miller, Brad M. Bebout, Kristen S. Habicht, Samuel M. Webb, David A. Stahl Aug 2007

High Rates Of Sulfate Reduction In A Low-Sulfate Hot Spring Microbial Mat Are Driven By A Low Level Of Diversity Of Sulfate-Respiring Microorganisms, Jesse G. Dillon, Susan Fishbain, Scott R. Miller, Brad M. Bebout, Kristen S. Habicht, Samuel M. Webb, David A. Stahl

Biological Sciences Faculty Publications

The importance of sulfate respiration in the microbial mat found in the low-sulfate thermal outflow of Mushroom Spring in Yellowstone National Park was evaluated using a combination of molecular, microelectrode, and radiotracer studies. Despite very low sulfate concentrations, this mat community was shown to sustain a highly active sulfur cycle. The highest rates of sulfate respiration were measured close to the surface of the mat late in the day when photosynthetic oxygen production ceased and were associated with a Thermodesuffiovibrio-like population. Reduced activity at greater depths was correlated with novel populations of sulfate-reducing microorganisms, unrelated to characterized species, and most …

Phylogeography Of The Thermophilic Cyanobacterium Mastigocladus Laminosus, Scott R. Miller, Richard W. Castenholz, Deana Pedersen Aug 2007

Phylogeography Of The Thermophilic Cyanobacterium Mastigocladus Laminosus, Scott R. Miller, Richard W. Castenholz, Deana Pedersen

Biological Sciences Faculty Publications

We have taken a phylogeographic approach to investigate the demographic and evolutionary processes that have shaped the geographic patterns of genetic diversity for a sample of isolates of the cosmopolitan thermophillic cyanobacterial Mastigocladus laminosus morphotype collected from throughout most of its range. Although M. laminosus is found in thermal areas throughout the world, our observation that populations are typically genetically differentiated on local geographic scales suggests the existence of dispersal barriers, a conclusion corroborated by evidence for genetic isolation by distance. Genealogies inferred using nitrogen metabolism gene sequence data suggest that a significant amount of the extant global diversity of …
