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.

Chlorophacinone Baiting For Belding’S Ground Squirrels, Craig A. Ramey, George H. Matschke, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

The efficacy of using 0.01% chlorophacinone on steam-rolled oat (SRO) groats applied in CA alfalfa by spot-baiting/hand baiting around burrow entrances (~11.5 g) to control free-ranging Belding's ground squirrels (Spermophilus beldingi) were compared in 6 randomly assigned square treatment units (TUs). Four TUs were given the rodenticide and 2 treated with placebo bait. Each TU was a 0.4 ha square surrounded by a similarly treated 5.5 ha square buffer zone. Baits were applied on May 13 and re-applied, on May 20 and May 22, after 7 days of un-forecasted cool wet weather greatly reduced their above ground activity. Pesticide (EPA …

University Of Nebraska-Lincoln School Of Natural Resources Review: Final Report, December 2003, Michael O'Neill, Phaedra Budy, Stephen Degloria, Ed Kanemasu, Jamie Robertson, Derrel Martin, Anne K. Vidaver, Tylr Naprstek, Donna Woudenberg

School of Natural Resources: Documents and Reviews

In July 2003, the School of Natural Resource Sciences was merged with the Conservation and Survey Division and the Water Center Nebraska State Survey. This merger produced the School of Natural Resources (hereafter referred to as the "School") in its current form. The University of Nebraska-Lincoln requested a ten-year review of the School's programs and activities. The review was administered by the Cooperative State Research, Education and Extension Service (CSREES) in cooperation with the University of Nebraska-Lincoln's Institute of Agriculture and Natural Resources, the College of Agriculture, and the School.

The review document is divided into nine sections. The first …

A Report On Black-Tailed Prairie Dogs In Nebraska, Their Biology, Behavior, Ecology, Management, And Responses To A Visual Barrier Fence, Nancy S. Foster

School of Natural Resources: Dissertations, Theses, and Student Research

I examined the effects of a visual barrier fence, which had a see-through visibility of 600/0, on the foraging, vigilance, and aggressive behaviors of adult female black-tailed prairie dogs from June through August 1990 in central Nebraska. I also examined changes in their home ranges and use of an area in response to this fence. Prairie dogs prefer an open view of their surroundings. Therefore, I expected animals near a visual barrier to spend more time in vigilance and aggression, and less time foraging. Adult female prairie dogs exposed to the visual barrier devoted more time to foraging and less …

Leaf Optical And Indirect Lai Measurements In Wheat And Alfalfa At Maciv: Agmet Progress Report 89-4, E. A. Walter-Shea, B. L. Blad

School of Natural Resources: Documents and Reviews

Interpretation of remotely sensed vegetative surfaces requires an understanding of the interaction of radiation with the various components of vegetation. Leaves are the most important component. Thus it is important to know the optical properties of individual leaves as well as the amount and distribution of leaves making up the vegetative cover. The objectives of our study were 1) to characterize the reflectance from and transmittance through adaxial and abaxial surfaces of individual wheat and alfalfa leaves and 2) to compare the traditional, time-consuming, destructive method of estimating LAI (direct method) to a relatively quick, indirect estimate of LAI in …
