The Relationship Between Time And Plant Diversity In Prairie Restorations Within The Prairie Corridor On Haines Branch, Elizabeth Park
The Relationship Between Time And Plant Diversity In Prairie Restorations Within The Prairie Corridor On Haines Branch, Elizabeth Park
Department of Environmental Studies: Undergraduate Student Theses
This study focuses on better understanding the relationship between the age of prairie restorations and their plant diversity. The study looks specifically at the prairie restorations within the Prairie Corridor on Haines Branch, located west of Lincoln, Nebraska. The data gathered from these restorations show a positive correlation between age and native plant diversity. This diversity indicates that the restorations are fulfilling their purpose by bringing native prairie plants back to the area. From the data I came to these four conclusions, 1) Because the study only included two restorations greater than 10 years old, it is unclear if the …
Impacts Of Plant Size, Density, Herbivory, And Desease On Native Platte Thistle (Cirsium Canescens), Deidra Jacobsen
Impacts Of Plant Size, Density, Herbivory, And Desease On Native Platte Thistle (Cirsium Canescens), Deidra Jacobsen
Department of Environmental Studies: Undergraduate Student Theses
Abstract. Based on prior field observations, we hypothesized that individual and interacting effects of plant size, density, insect herbivory, and especially fungal disease, influenced seedling and juvenile plant growth in native Platte thistle populations (Cirsium canescens Nutt.). We worked at Arapaho Prairie in the Nebraska Sandhills (May - August 2007), monitoring plant growth, insect damage, and fungal infection within different density thistle patches. In the main experiment, we sprayed half of test plants in different density patches with fungicide (Fungonil© Bonide, containing chlorothalonil) and half with a water control. Fungal infection rates were very low, so we found no difference …
Evaluating Hazelnut Cultivars For Yield, Quality And Disease Resistance, Sam Tobin
Evaluating Hazelnut Cultivars For Yield, Quality And Disease Resistance, Sam Tobin
Department of Environmental Studies: Undergraduate Student Theses
ABSTRACT This long term study focuses on testing various hazelnut cultivars for yield, nut quality and disease resistance. There are various cultivars that are being tested for these desired traits but only the Grand Traverse and Skinner will be applicable for the results of this localized study. The desired traits of commercial nut production are best matched by these two cultivars. Results from previous harvests will be used to draw trends to recommend commercially functional cultivars in Eastern Nebraska.
Variations In Stomatal Traits Of 14 Bornean Tree Species Growing On Soils With Different Moisture Contents In Lambir Hills National Park, Whitney Logan Cannon
Variations In Stomatal Traits Of 14 Bornean Tree Species Growing On Soils With Different Moisture Contents In Lambir Hills National Park, Whitney Logan Cannon
Department of Environmental Studies: Undergraduate Student Theses
The goal of this study was to look at variations in stomatal traits of tree species on soils with different moisture contents and fertility at Lambir Hills National Park. Stomates are important structures on the surface of leaves that mediate conduction of moisture and gassesin and out of the leaf. If stomatalt raits are important for regulation, then there should be variation in stomatal traits in regards to their soil specialization.
