Fisheries resources face a confluence of socio-ecological challenges, the resolution of which requires interdisciplinary scientific information for sustainable utilization and management. The present study assessed gaps and challenges in Lake Victoria fisheries resources management for better research focus, policy formulation and improved governance of the fishery towards sustainability. Using key informant interviews and a plenary discussion with trans-disciplinary experts regarding Lake Victoria fisheries research, management and policy sectors, the present study identified current management challenges, gaps and priorities. The present study results indicate a constantly increasing fishing effort, poor enforcement of existing regulations and pollution and invasive weeds pose the …

Resilience Of Working Agricultural Landscapes, Shana Sundstrom, Jennifer Hodbod, Craig R. Allen Jan 2022

Resilience Of Working Agricultural Landscapes, Shana Sundstrom, Jennifer Hodbod, Craig R. Allen

School of Natural Resources: Faculty Publications

Many alternative agricultural approaches have been developed as a response to the social and ecological costs of modern industrialized agriculture. These include diversified, organic, sustainably intensified, and ecologically intensified farming systems, each of which addresses different aspects of agriculture as a social-ecological system. However, clear theoretical models that account for human-nature coupling and the importance of scale are lacking. Global change, including climate change, land use change, and other human activities influencing social-ecological systems, is exacerbating uncertainty regarding agriculture system dynamics and increasing the need for comprehensive models that include a dynamical integration of socio-ecological-economic influences. Resilience theory and related …

Remnant Prairies And High-Diversity Restorations Work Together To Support Wild Bees Season-Long, Katie Lamke, David A. Wedin, Judy Wu-Smart Jan 2022

Remnant Prairies And High-Diversity Restorations Work Together To Support Wild Bees Season-Long, Katie Lamke, David A. Wedin, Judy Wu-Smart

School of Natural Resources: Faculty Publications

The presence of diverse bee communities in an ecosystem is vital for maintaining healthy plant communities, promoting habitat resilience, and supporting agriculture. In the US, wild bee declines have led to increased monitoring efforts, but there remain critical data gaps in much of the Midwest. Here, we sought to examine how variation in richness and abundance of flowering forbs influences the richness and abundance of wild bees across “remnant” tallgrass prairies, “high diversity” prairie restorations, and “low diversity” prairie restorations or degraded grasslands in eastern Nebraska. High-diversity plots attracted no bees in the early season due to a lack of …

A Greenhouse Gas Emissions Inventory For Nebraska: Livestock And Coal Loom Large, Eric R. Holley, Adam Liska Jan 2022

A Greenhouse Gas Emissions Inventory For Nebraska: Livestock And Coal Loom Large, Eric R. Holley, Adam Liska

Adam Liska Papers

Mitigation of climate change requires the systematic identification and cataloging of emissions sources at city, state, and national levels. In this study, an inventory of annual greenhouse gas emissions from the state of Nebraska was created based on industry data, and emissions inventories were completed each year from 1990 to 2016. Nebraska’s net emissions were found to increase from 56.2 million metric tons of carbon dioxide equivalents (MMtCO2e) in 1990 to 87.4 MMtCO2e in 2016. Agriculture was found to be the sector with the most emissions (36 MMtCO2e) followed by electricity generation (21 MMtCO …

Assessment Of The Negative Role Amur Honeysuckle Has On Urban Forest Diversity, Hayley Schlabowske, Paige Lundborg, Jason Koontz, Michael Reisner

Independent Research Projects

Lonicera maackii (Amur Honeysuckle), an invasive shrub species, has out-competed native species in urban riparian zones for decades due to its ability to receive more sunlight and it also secretes an allelochemical from its leaves that negatively impacts the ecosystems. Our research question is how does Lonicera maackii affect native plant species in the herbaceous understory? Five forest communities were sampled in Northwest Illinois. Sites were separated into four different categories with L. maackii only, Garlic Mustard (Alliaria petiolata) only, Neither invasive species, and sites where both occur. There were 12 sites for each of the four categories resulting in …

Effect Of Nest Box Temperature Mitigation Treatments On Nest Success And Nestling Condition In A Southeastern Population Of Eastern Bluebirds (Sialia Sialis), Christopher G. Horacek, Katie Stumpf, Wayne Powell Jan 2022

Effect Of Nest Box Temperature Mitigation Treatments On Nest Success And Nestling Condition In A Southeastern Population Of Eastern Bluebirds (Sialia Sialis), Christopher G. Horacek, Katie Stumpf, Wayne Powell

Graduate Research Showcase

Understanding behavioral responses of wildlife to climate change will be important as global temperatures continue to rise. Effects of rising temperatures may impact many species, including those that breed in seemingly protected nests, such as cavity nesting birds. Variations in nest cavity microclimate during the early development of secondary cavity nesting passerines may affect the growth of offspring and impact nesting success and survival. We examined the effect of two heat mitigation treatments (white exterior, n=11, and an internal foil heat shield, n=16) and nest box opening orientation (north, south, east, west) on internal nest box temperatures and the effect …

Ferrihydrite Enrichment In The Rhizosphere Of Unsaturated Soil Improves Nutrient Retention While Limiting Arsenic And Uranium Plant Uptake, Arindam Malakar, Daniel D. Snow, Michael Kaiser, Jordan Shields, Bijesh Maharjan, Harkamal Walia, Daran Rudnick, Chittaranjan Ray Jan 2022

Ferrihydrite Enrichment In The Rhizosphere Of Unsaturated Soil Improves Nutrient Retention While Limiting Arsenic And Uranium Plant Uptake, Arindam Malakar, Daniel D. Snow, Michael Kaiser, Jordan Shields, Bijesh Maharjan, Harkamal Walia, Daran Rudnick, Chittaranjan Ray

Nebraska Water Center: Faculty Publications

Improvement of nutrient use efficiency and limiting trace elements such as arsenic and uranium bioavailability is critical for sustainable agriculture and food safety. Arsenic and uranium possess different properties and mobility in soils, which complicates the effort to reduce their uptake by plants. Here, we postulate that unsaturated soil amended with ferrihydrite nanominerals leads to improved nutrient retention and helps reduce uptake of these geogenic contaminants. Unsaturated soil is primarily oxic and can provide a stable environment for ferrihydrite nanominerals. To demonstrate the utility of ferrihydrite soil amendment, maize was grown in an unsaturated agricultural soil that is known to …

CERCOM Reports

The Center for Environmental Research and Coastal Oceans Monitoring (CERCOM) visits 11 locations in the Great South Bay from Memorial Day – Labor Day to monitor dissolved oxygen (DO), pH, salinity, clarity and temperature. Students are trained to assist in CERCOM’s water quality data collection by research assistant Mr. Kyle Maurelli. This monitoring program has been conducted for the past 17 years. These parameters are critical in determining long term water quality conditions in Long Island estuaries
