Invasive Species Handbook: A Resource For Educators - Grades 3-8, Natalie D'Souza, Marion Murray, Lori R. Spears

All Current Publications

This handbook includes six chapters that discuss invasive species and their environmental, economic, and health impacts. It also reviews pathways of invasive species spread and prevention, monitoring, and control. The handbook is a resource for educators teaching children in grades 3 through 8. Learning objectives, activities, and vocabulary are also included.

Social And Cultural Dynamics Of Non-Native Invasive Species, John Schelhas, Janice Alexander, Mark W. Brunson, Tommy Cabe, Alycia Crall, Michael J. Dockry, Marla R. Emery, Susan J. Frankel, Nina Hapner, Caleb R. Hickman, Rebecca Jordan, Michael J. Lavoie, Zhao Ma, Joe Starinchak, Jelena Vukomanovic

Invasive species and their management represent a complex issue spanning social and ecological systems. Invasive species present existing and potential threats to the nature of ecosystems and the products and services that people receive from them. Humans can both cause and address problems through their complex interactions with ecosystems. Yet, public awareness of invasive species and their impact is highly uneven, and public support for management and control of invasive species can be variable. Public perceptions often differ markedly from the perspectives of concerned scientists, and perceptions and support for management are influenced by a wide range of social and …

The First Record Of Raccoon Dog (Nyctereutes Procyonoides) In Turkey, Morteza Naderi, Emrah Çoban, Josip Kusak, Mübeccel Çisel Kemahli Aytekin, Mark William Chynoweth, İsmail Kayahan Ağirkaya, Neslihan Güven, Ayşegül Çoban, Çağan Hakkı Şekercioğlu

The raccoon dog (Nyctereutes procyonoides) was recorded for the first time in Turkey on May 10, 2019, and June 5, 2019, in the same location after 4668 nights of camera trapping in the forests of the Sarıkamış region and Allahuekber Mountains in eastern Turkey. It was recorded in a Scots pine (Pinus sylvestris) forest at 2340 m above sea level with extensive snow cover. Given that the nearest known population is in the forests of Georgia approximately 105 km away, there may already be a viable population in Turkey. As an omnivorous species with a high …

Genomic Variation Of Introduced Salvinia Minima In Southeastern United States, Carol A. Rowe, Donald P. Hauber, Paul G. Wolf

Ecology Center Publications

Common salvinia, Salvinia minima Baker (Salviniaceae), is a small, floating aquatic fern native to Central and South America that has invaded fresh water bodies in southeastern United States since the 1930s. We examined genetic variation across much of the introduced range of this species in the United States using codominant RAD-seq markers. Data from over 600 variable loci showed a reduction in heterozygosity from east to west in addition to a corresponding trend in assignment of samples to one of two genetic groups. Our data are consistent with previous published work and with the hypothesis that common salvinia had a …

Testing Rearing Diets For A New Invasive Insect Pest In Utah, The Brown Marmorated Stink Bug, James Withers, Loren Linford

Research on Capitol Hill

The brown marmorated stink bug (BMSB), Halyomorpha halys, is an invasive insect from Asia. It has caused millions of dollars in damage to fruit, vegetable, ornamental, and field crops since its arrival in North America, and can be a severe nuisance pest when it congregates on human structures to overwinter. The BMSB caused $37 million of apple crop damage in the Mid-Atlantic Region in 2007 to 2010. To study the insect, effective rearing methods are needed. Previous research (Funayama 2004 & 2006; Medal et al. 2012) showed that carrot, raw peanut and soybean increased rearing efficiency. Recent lab experience …

Comparison Of Burbot Populations Across Adjacent Native And Introduced Ranges, Annika W. Walters, Elizabeth G. Madenville, W. Carl Saunders, Paul C. Gerrity, Joseph A. Skorupski, Zack E. Underwood, Eric I. Gardunio

Watershed Sciences Faculty Publications

Introduced species are a threat to biodiversity. Burbot, Lota lota, a fish native to the Wind River Drainage, Wyoming and a species of conservation concern, have been introduced into the nearby Green River Drainage, Wyoming, where they are having negative effects on native fish species. We compared these native and introduced burbot populations to evaluate potential mechanisms that could be leading to introduction success. We examined genetic ancestry, physical habitat characteristics, community composition, and burbot abundance, relative weight, and size structure between the native and introduced range to elucidate potential differences. The origin of introduced burbot in Flaming Gorge …

Rooted In Hell: Predicting Invasion Rates Of Phragmites Australis, Rachel Nydegger, Jacob P. Duncan, James A. Powell

Browse All Undergraduate research

Across the estuaries of the east coast and wetlands of the Great Lakes, the invasive grass Phragmites australis outcompetes other vegetation and destroys local ecosystems. Because its roots are tolerant to salinity that other plants find hellish, Phragmites invasions begin with vegetative spread of genetic clones in brackish marshlands. This plant can grow over three meters tall at densities of 50 stems/m2, provides poor wildlife habitat, and is very difficult to eradicate.

A discrete life stage model on a yearly time step captures seed survivorship in a seed bank, sexual and asexual recruitment into a juvenile age class, and differential …

Phragmites Australis Management In The United States: 40 Years Of Methods And Outcomes, Eric L. G. Hazelton, Thomas J. Mozdzer, David M. Burdick, Karin M. Kettenring, Dennis F. Whigham

Watershed Sciences Faculty Publications

Studies on invasive plant management are often short in duration and limited in the methods tested, and lack an adequate description of plant communities that replace the invader following removal. Here we present a comprehensive review of management studies on a single species, in an effort to elucidate future directions for research in invasive plant management. We reviewed the literature on Phragmites management in North America in an effort to synthesize our understanding of management efforts, identify gaps in knowledge and improve the efficacy of management. Additionally, we assessed recent ecological findings concerning Phragmites mechanisms of invasion and integrated these …

Cooperation And Coordination Are Invasive Species: Important For Effective Management Of Invasive Weeds, U.S. Government Accountability Office

All U.S. Government Documents (Utah Regional Depository)

Invasive weeds, native or nonnative plant species, cause harm to natural areas such as rangelands or wildlife habitat and economic impacts due to lost productivity of these areas. While the federal investment in combating invasive species is substantial most has been concentrated on agricultural lands, not on natural areas. In this report, GAO describes (1) the entities that address invasive weeds in natural areas and the funding sources they use; (2) federal, state, and local weed management officials’ views on the barriers to weed management; and (3) their opinions about how additional resources for weed management could be distributed. GAO …
