The Distribution And Life Cycle Of Alliaria Petiolata In Lincoln, Nebraska, Caleb Pharris
The Distribution And Life Cycle Of Alliaria Petiolata In Lincoln, Nebraska, Caleb Pharris
Department of Environmental Studies: Undergraduate Student Theses
Alliaria petiolata (Garlic Mustard) is a biennial alien invasive plant species of the Brassicacea family. It is responsible for displacing native plant species throughout North America and its management has proven to be extremely difficult. Recently several populations of Alliaria petiolata have been discovered in southwestern Lincoln, Nebraska. The spread of Alliaria petiolata is a concern for natural resource managers and the general public. Due to the difficulty of its control, Alliaria petiolata is capable of creating monocultures which diminish the aesthetic value of an ecosystem. While most commonly found in the understory of hardwood forests, it is capable of …
Rebound In Us Productive Sectors, Harry D. Saunders
Rebound In Us Productive Sectors, Harry D. Saunders
Harry D. Saunders
This presentation describes rebound measurements in the US economy, the dominance of "embedded energy" (production-side energy use), and the economic costs of polices to mitigate rebound effects.
An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders
An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders
Harry D. Saunders
This paper introduces a new decomposition of energy consumption to reveal the effects of consumer income levels on energy use. It concludes that the great bulk of energy consumption in the US is embedded in goods and services purchased by consumers and that this component of energy demand is growing more rapidly than direct use of energy by households owing to the preferences of high-income consumers. Significantly, this embedded component of energy demand has historically experienced large rebound magnitudes. The analysis also concludes that energy consumption is driven by more than just income level, with the lowest-income consumers using more …
Trap Shyness And Avoidance Affects On Capture Proportions Of Dipodomys Heermanni Arenae, Natalie E. Folsom, Andrew R. Ruddock
Trap Shyness And Avoidance Affects On Capture Proportions Of Dipodomys Heermanni Arenae, Natalie E. Folsom, Andrew R. Ruddock
Biological Sciences
This is a study on trap shyness and trap avoidance in the kangaroo rat species Dipodomys heermanni arenae. This species is being studied as a surrogate for the critically endangered Dipodomys heermanni morroensis. This is an ongoing study that has been continuing for the past three years, with four three-day sessions per year. The study is a specific look at the effects of the use of Sherman traps on kangaroo rat behavior between individual session days. Capture proportions for each of the three days of each session were calculated and compared through a t-test. The current results of …
