Effects Of Amur Honeysuckle On Soil Co2 Emissions, Aidan Shumaker Apr 2019

Effects Of Amur Honeysuckle On Soil Co2 Emissions, Aidan Shumaker

Student Symposium

Lonicera maackii is an invasive woody species found in Ohio and throughout the deciduous forests of eastern United States, taking over habitats of native shrub species such as Lindera benzoin. L. maackii has unique traits compared to deciduous forest natives, showing earlier leaf-out and later leaf senescence, higher leaf nitrogen levels, and faster leaf decomposition. As a result, L. maackii may alter soil conditions through its extended root activity and impacts on microbial decomposition, possibly impacting soil CO2 emissions. As soil microorganisms metabolize organic matter, they release greenhouse gases like CO2 through respiration, which can impact global climate change. Previous ...

In this teaching module, students will explore emerald ash borer (EAB), its impacts on the ash trees, and how warming temperatures could affect EAB populations. The emerald ash borer is a green buprestid or jewel beetle native to north-eastern Asia that causes devastating disease in ash trees.


Predation And Disease-Related Economic Impacts Of Wild Pigs On Livestock Producers In 13 States, Aaron M. Anderson, Chris Slootmaker, Erin Harper, Ryan S. Miller, Stephanie A. Shwiff Jan 2019

Predation And Disease-Related Economic Impacts Of Wild Pigs On Livestock Producers In 13 States, Aaron M. Anderson, Chris Slootmaker, Erin Harper, Ryan S. Miller, Stephanie A. Shwiff

USDA National Wildlife Research Center - Staff Publications

We report the results of a survey on wild pigs (Sus scrofa) damage to livestock producers in 13 US states (Alabama, Arkansas, California, Florida, Georgia, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas). The survey was distributed by the USDA National Agricultural Statistical Service in the summer of 2017 to a sample of livestock producers in the 13-state region. Findings indicate that predation and disease-related damage can be substantial in certain states and for certain types of livestock. In particular, damage to cattle operations in Texas and Arkansas was substantially higher than damage in other states and types ...


Feral Swine Harming Insular Sea Turtle Reproduction: The Origin, Impacts, Behavior And Elimination Of An Invasive Species, Richard M. Engeman, Robert W. Byrd, Jamie Dozier, Mark A. Mcalister, James O. Edens, Elizabeth M. Kierepka, Timothy J. Smyser, Noel Myers Jan 2019

Feral swine are among the world's most destructive invasive species wherever they are found, with translocations figuring prominently in their range expansions. In contrast, sea turtles are beloved species that are listed as threatened or endangered throughout the world and are the focus of intense conservation efforts. Nest predation by feral swine severely harms sea turtle reproduction in many locations around the world. Here we quantify and economically assess feral swine nest predation at North Island, South Carolina, an important loggerhead sea turtle nesting beach. Feral swine depredation of North Island sea turtle nests was first detected in 2005 ...


Mycorrhizal Colonization And Its Relationship With Plant Performance Differs Between Exotic And Native Grassland Plant Species, Aleksandra Checinska Sielaff, H. Wayne Polley, Andres Fuentes-Ramirez, Kirsten Hofmockel, Brian J. Wilsey Jan 2019

Mycorrhizal Colonization And Its Relationship With Plant Performance Differs Between Exotic And Native Grassland Plant Species, Aleksandra Checinska Sielaff, H. Wayne Polley, Andres Fuentes-Ramirez, Kirsten Hofmockel, Brian J. Wilsey

Ecology, Evolution and Organismal Biology Publications

Many grasslands have been transformed by exotic species with potentially novel ecological interactions. We hypothesized that exotic and native plant species differ, on average, in their percentage mycorrhizal colonization, and that mycorrhizal colonization is positively related to plant performance in the field. We compared colonization by arbuscular mycorrhizae (AM) fungi in perennial native and exotic species that were paired phylogenetically and by functional groups and grown under a common environment in field plots in Central Texas, USA. Roots were collected from plants in monoculture plots, stained, and percent colonization was assessed with a microscope. Aboveground biomass and dominance in mixture ...
