An Assessment Of The Competitive Ability Of Oak Species In The Central Hardwood Region Using Both Pre-Harvest Treatment Data And Stem Analysis Techniques, Robert William Edward Quackenbush
Open Access Theses
The density of advance regeneration of oak species has been in decline across the Central Hardwood Region (CHR) for the past 50 years. This phenomenon has been accredited to many different factors, ranging from predation and browse by wildlife, to human induced changes in the environment which include massive clearcutting, land use change from forest to agriculture, and suppression of fires which played an intricate role in the development of oak systems across the CHR. The objectives of this research project were to compare densities of oak advance regeneration across two different environmental gradients within the CHR, in particular the …

Effects Of Lake Erie Hypoxia On Fish Habitat Quality And Yellow Perch Behavior And Physiology, Leah Zoe Almeida
Open Access Theses
Hypoxia is a concern in freshwater, marine, and estuarine systems worldwide including in Lake Erie, North America. Hypoxia may develop more frequently and for a longer duration as a result of excess nutrient loading from human sources, therefore, the incidence of hypoxic areas has increased with human population increases and intensive land-use practices. The effects of hypoxia on fish and other aquatic organisms have been well-studied, but most research examines the negative aspects of hypoxia development on habitats and the effect of severe hypoxia on individuals. In this study we focused on less studied and more subtle effects of hypoxia, …
