White Nose Syndrome In Bats And Infant Mortality In Georgia, Rhys Medcalfe, Sean Medcalfe, Simon Medcalfe

Journal of the Georgia Public Health Association

Background: White nose syndrome (WNS) is a disease in bats caused by the fungus Pseudogymnoascus destructans that can result in bat mortality rates of over 90%. WNS was discovered in Georgia in 2012 in 3 counties but has continued to spread to 14 counties as of 2023, with P. destructans detected in a further seven. Biodiversity loss has been linked to human health outcomes including infant mortality. Understanding the link between WNS, biodiversity loss, and infant mortality in Georgia is important because Georgia ranks 42^nd out of the 50 states for infant mortality rate.

Predator Management With A Single Bait? Use Of Eradicat For The Simultaneous Management Of Feral Cats, Red Foxes, And Wild Dogs, Tracey L. Kreplins, David Algar

Biosecurity Research Articles

Context

In Western Australia, there are three invasive predators that require management for agriculture and biodiversity protection, feral cats, wild dogs, and red foxes. These three predators often coexist in the same locality, suggesting potential efficacy gains can be made via simultaneous control. While Western Australian native species have evolved a high tolerance to poison baiting (1080), invasive predators have not. Therefore, landscape-scale baiting is commonly used for predator management. Aims

Eradicat baits designed for feral cat control have also been known to be consumed and control wild dogs and foxes. In this trial, we aimed to evaluate Eradicat as …

Potential Economic Impact Of Grapevine Phylloxera (Hemiptera: Phylloxeridae) On Western Australian Winegrapes, David C. Cook, Andrew S. Taylor, Peter S. Gardiner, Rodrigo Pires, Hamish L R Mckirdy, Karen W. Holmes, Helen Spafford

Viticulture Research Articles

Grapevine phylloxera Daktulosphaira vitifoliae Fitch (Hemiptera: Phylloxeridae) has been present in Australia for almost 150 years but has not spread to south-west Western Australia, in part due to the relative isolation of the region. Recent improvements in tourist access, with interstate flights now arriving at Busselton Margaret River Airport, raise concerns about potential phylloxera introductions via wine tourism. In this paper, we simulate the potential economic impact on the Western Australian winegrape industry following a hypothetical arrival event in the Margaret River wine region. We use soil texture maps to assess the suitability of winegrape-growing areas to phylloxera establishment and …

What’S The Best Way To Store Toxic 1080 Baits?, Heather M. Crawford, Ricarda Fenske, Gerard Smith, Teen Ryan, Jamie (Frog) Taylor, Daniel Carlisle, Debbie Dowden, Dean Butcher, Tracey L. Kreplins, James Miller, Malcolm S. Kennedy, Patricia A. Fleming

Biosecurity Research Articles

Being able to store toxic baits could allow livestock producers to target ‘hot spots’ of predator activity, supplementing or even replacing broadscale baiting, therefore avoiding potential risk of bait-resistant populations. We compared 1080 dose recovered from dried meat baits (DMB; camel, horse and kangaroo) and sausage baits stored by different methods (shed, locked transport box, freezer, cryo-vacuumed) to identify whether they were still lethal, and address concern that freezing/thawing could result in loss of the water-soluble 1080 toxicant. We developed a bait collection method to halt microbial activity (preserving 1080 dose), al-lowing collection of baits manufactured under field conditions by …

Ndp 54 V1 - National Diagnostic Protocol For Meadow Spittlebug (Philaenus Spumarius), Melinda Moir

Biosecurity research reports

National Diagnostic Protocols (NDPs) are diagnostic protocols for the unambiguous taxonomic identification of plant pests. NDPs:

• are a verified information resource for plant health diagnosticians
• are consistent with ISPM No. 27 – Diagnostic Protocols for Regulated Pests
• provide a nationally consistent approach to the identification of plant pests enabling transparency when comparing diagnostic results between laboratories; and,
• are endorsed by regulatory jurisdictions for use (either within their own facilities or when commissioning from others) in a pest incursion.

Where an International Plant Protection Convention (IPPC) diagnostic protocol exists it should be used in preference to NDPs, unless it is shown …

Consultation Summary For Proposed Declared Pest Rates 2025/2026, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

Under the Biosecurity and Agriculture Management Act 2007 (BAM Act) the State raises a Declared Pest Rate (DPR) from land or leaseholders (hereafter landholders) in prescribed areas (DPR Areas) and matches the funds raised from the rate dollar-for-dollar.

The combined funds are made available to Recognised Biosecurity Groups (RBGs) who provide support to landholders to fulfil their obligations under the BAM Act to manage widespread and established declared pests on their land. A community-led and coordinated approach is considered the most effective way to support landholders to manage these types of pests.

An Economic Analysis Of Cell-Fencing In Semi-Arid Rangelands, Stuart Dawson, Tracey L. Kreplins, Malcolm S. Kennedy, Santhi Wicks, Patricia A. Fleming

Biosecurity Research Articles

In Australia, livestock predation by dingoes (Canis familiaris) has contributed to what some livestock producers consider a dire situation for rangeland pastoralism, driving demand for cooperative regional-scale exclusion (‘cell’) fencing (i.e. pest-proof fences that encompass one or more individual properties) and landscape-scale predator control. The present case study predicted the effect of four cell-fences in the state of Western Australia (WA) on the gross margin of sheep (for meat or meat and wool) and cattle pastoral enterprises. We modelled the potential effects of the following four key variables: (1) four levels of commodity prices, (2) five levels of …

Evaluation Of Variable Selection Techniques On The Genetic Architecture Of Flowering Time In Maize, Felix Yeboah

Data Science and Data Mining

In this project, we investigate several variable selection procedures to give an overview of how well they perform on a genomic dataset using three different penalized regression approaches. Comparisons between different methods were performed. These methods include Ridge, lasso, and Elastic Net. We utilized 4494 observations with 7389 SNPs gene scores to predict time to male flowering (dtoa). We assessed the performance of these three models in terms of mean square error. Not surprisingly, Lasso and Elastic Net perform better than Ridge Regression. Overall, Elastic Net performed better in predicting the time of male flowering (dtoa).

Modeling Wild Rice Bed Health: A Dual Metric Approach For Bed Strength And Invasive Impact, Seth Sisneros-Martinez

Journal of Earth and Life Science

Wild rice (mannoomin; Zizania palustris) is an aquatic grain that grows in slow-moving rivers and shallow bays throughout northern Minnesota. In Headquarters Bay on Leech Lake, wild rice has served as a cultural staple for Indigenous communities for centuries. However, its population has declined in recent years due to multiple environmental issues. One potential contributor is Eurasian watermilfoil (Myriophyllum spicatum; EWM), an invasive species that forms dense mats capable of outcompeting native aquatic vegetation, including wild rice. EWM was first recorded on the southern shoreline of Leech Lake in 2005 and has since become widespread. This study …

Effects Of Round-Up On The Environment, Sandra J. Marcu

Journal of Earth and Life Science

Many people around the world have used and still currently use Roundup but are unaware of the effects it has on the environment. Roundup is a spray on application weedkiller that is widely used around the world today both residentially and commercially. It enables its user to grow a garden or a field of crops with a no-tilling approach to eliminate weeds. It is a well-known and popular choice for killing weeds that has been around since the mid 1970’s (Oca, 2017). John Franz, a Monsanto scientist discovered that glyphosate (main ingredient in Roundup) was an herbicide or weedkiller, and …

The Impact Staphylococcus Aureus Has On Conventional And Organic Dairy Herds In New Hampshire And New York, Jacqueline Rose Holmes

Honors Theses and Capstones

Staphylococcus aureus is a potentially virulent bacterium that causes mastitis in dairy cattle. The toxins produced from S. aureus impact host immunity, damage the mammary gland, and can adapt to cause antimicrobial resistance. It is important to manage both organic and conventional farms correctly by practicing proper hygiene while milking and providing a clean environment. There is a significant increase of S. aureus cases on organic farms compared to conventional, so there may be ways in which organic management and treatment options could be altered to reduce economic loss and animal suffering. The thesis focuses on the involvement S. aureus …
