Developing Youth Leadership through Community Gardening: Opportunities and Outcomes
Beres, Michelle ( 2013-05 )Community gardens exist throughout Ohio and are associated with a variety of organizations. Little prior research has looked at youth involvement and leadership in these gardens. This study examined leadership opportunities ... -
The Effect of Acclimation to Hypoxia on Fish Sensitivity to Ammonia
Medberry, Robert ( 2014-12 )Aquaculture is a rapidly growing field that has potential to help solve world issues such as food shortages and agricultural sustainability. Winterkill is a naturally occurring event in which ice accumulation on shallow ... -
The effect of Lake Erie algal blooms on Emerald Shiner (Notropis atherinoides) visual morphology
Bertolini, Elizabeth ( 2017-05 )Due to recent increases in agricultural runoff, Lake Erie has been experiencing harmful algal blooms (HABs) with rising severity. The runoff carries excess Phosphorus which is a limiting nutrient in freshwater and a main ... -
The Effect of the Lead Water Crisis as a Focusing Event on Cooperation and Conflict Among Actors in Sebring, Ohio
Satterfield, Jennifer ( 2017-12 )At the same time the Flint water crisis made national news in late 2015 and early 2016, a local lead water crisis was taking place in Sebring, Ohio. This lead water crisis in Sebring was a focusing event that opened a ... -
Effects of aquatic habitat degradation on hybridization between two species of Sunfish: Bluegill (Lepomis macrochirus) and Green Sunfish (Lepomis cyanellus)
Wittman, Jacob ( 2016-05 )Stream habitat degradation includes factors such as as increased turbidity and excessive sedimentation of the streambed resulting from surrounding urban land use and development. It is hypothesized that these two physical ... -
Effects of burning season on recorded fire temperature and the regeneration of oak species
Nadler, Elisabeth ( 2014-05 )The composition of eastern deciduous forests has changed within the last 100 years as a result of decreased natural fire disturbances. The presence of oak (Quercus spp.) has greatly declined, and has been increasingly ... -
The effects of canopy density and vegetative competition on oak seedling numbers in southeastern Ohio
Rist, Stephen G. ( 2006-06 )The regeneration of oak species in the forest setting has been a current issue for foresters. Oak-hickory forests are currently the dominant cover type in most parts of the Eastern Hardwood Region, but the lack of ... -
Effects of Dietary Thiamine and Magnesium on Lake Trout with Induced Early Mortality Syndrome (EMS)
Smith, Brittany ( 2009-12 )Multiple stressors contribute to Early Mortality Syndrome (EMS) in salmonid fisheries and its effects on the Great Lakes region, but the factors responsible for the variation of EMS are not clearly understood. EMS is as a ... -
Effects of Fire and Invasive Paulownia tomentosa on Native Tree Regeneration in Southern Ohio After Two Years
Neel, Alina ( 2012-06 )Paulownia (Paulownia tomentosa) is a tree native to southeast Asia that has shown invasive behavior in the eastern United States. The objective of this project was to determine the effects of paulownia invasion, wildfire, ... -
Effects of Honeysuckle (Lonicera maackii) Management on Avian Abundance
Wenner, Carolyn ( 2013-05 )Amur honeysuckle (Lonicera maackii) is an invasive shrub that is found in many parts of Ohio and grows well in Ohio's forest ecosystems. This study attempted to assess the effect of treating Amur honeysuckle on avian ... -
The Effects of Intraspecific Variation of Crayfish Behavior on Nutrient Cycling in Aquatic Environments
Acheson, Paul ( 2020-05 )Human activities are rapidly altering species traits at a global scale. Yet, there remains a critical need to determine whether trait variation within species affects ecosystem responses to global change. In particular, ... -
Effects of N:P Ratio on the Occurrence of Harmful Algal Blooms
Palus, James ( 2015-05 )Urban and agricultural development has had dramatic effects on the biogeochemical cycles of nitrogen (N) and phosphorus (P). Such nutrient-rich conditions cause cyanobacteria to dominate the phytoplankton, thereby causing ... -
The Effects of Natural Capital Investment on Coastal Resilience to Natural Hazards
Shea, Andrew ( 2018-12 )Over half of the world’s population lives and works near the coast. Climate change poses an increasing inherent risk to coastal communities. Rising sea level and increased frequency and intensity of natural disasters have ... -
