Electronic Theses and Dissertations
The food habits of bluegills (Lepomis macrochirus), black bullheads Ictalurus melas), and muskellunge (Esox masquinongv) in the Big Stone Power Plant cooling reservoir were studied from January through December 1979. The diet of 794 bluegills >50 mm TL was dominated by vegetation, planktonic crustaceans, dipteran larvae and pupae, and fishes: 214 bluegills < 50 mm TL fed primarily upon chironomid larvae and pupae and cladocerans. There was a significant difference (P50 mm. This was determined by Spearman rank correlation coefficients based upon percent number and percent volume of food items, and mean number of taxa per stomach. Both bluegill length-groups positively selected Chydorinae, ostracods, Caenis spp. larvae, chironomid pupae, and Physa spp., while they negatively selected cyclopoid copepods, Ceriodaphnia spp., and Tanypodinae larvae. Chironomid larvae were positively selected by bluegills mm, but were negatively selected by those >50 mm. Fishes and chironomid larvae were the major food items of 105 black bullheads >120 mm TL; fishes and filamentous algae were the dominant food items of 146 bullheads 5120 mm. Ostracods and dipteran pupae were positively selected, while Tanvpodinae and Chironominae larvae were negatively selected. Chydorinae, …

The use of thermography for monitoring soil moisture is based on the sensitivity of thermal emittance to surface temperature. Any factor which causes a variation in …
Applications Of X-Ray Single Crystal Diffraction To Structure Determination, Bih- Lian Huang
Applications Of X-Ray Single Crystal Diffraction To Structure Determination, Bih- Lian Huang
Electronic Theses and Dissertations
X-ray diffraction methods frequently give unequivocal answers about structure in the solid state. Single-crystal X-ray diffraction methods have been used for structure determination since the 1930’s. The primary aim of a crystal structure analysis by X-ray diffraction is to obtain a detailed picture of the contents of the crystal at the atomic level. Once this information is available, and the positions of the individual atoms are known precisely, one can calculate interatomic distances, bond angles, and other features of the molecular geometry that are of interest, such as the planarity of a particular group of atoms, the angles between planes, …

Nesting And Brood Rearing Ecology Of The Vancouver Canada Goose On Admiralty Island Southeast Of Alaska, Charles S. Lebeda
Nesting And Brood Rearing Ecology Of The Vancouver Canada Goose On Admiralty Island Southeast Of Alaska, Charles S. Lebeda
Electronic Theses and Dissertations
Nesting and brood rearing biology of Vancouver Canada geese (Branta canadensis fulva) was studied in 1978 (preliminary) and from April-August 1979 in Seymour Canal, Admiralty Island, Alaska. Geese used trees for perching during the incubation period (24 April-7 June) and use was significant (P < .0001) for early morning hours. This behavior is considered unique among all Canada goose subspecies. An average of 86.3 search hours were conducted for each of 19 active nests located in 1979. Seven additional nests from previous years were also located. Twenty-two nests were located in forest habitat •. All forest nests were in association with vegetation similar to vegetation described for U.S. Forest Service classification of F4 and F5 (poorly drained) soil types. Mean clutch size was 4.4 ± 1.3 eggs. Mean egg length and width were 86.1 mm± 3.14 and 56.4 mm± 2.76, respectively. Success of all nests hatching at least one egg was 55.6%. Egg hatching success of successful nests was 95.7%. Total hatching success of all eggs was 62.0%. Forest habitat was used extensively for brood rearing. Broods generally avoided large bodies of water. Single family broods were found most often in forest habitat while creches were more common in meadows and intertidal zones. Breeding adults and goslings were comparatively less vocal in the forest. Goslings less than 2 weeks of age used forest habitat extensively and shifted to forest edge and intertidal zones with age. Forest habitats, rather than open water, were used as escape cover by breeding adults and broods. Nesting and brood rearing habitat was similar, thus, nest site selection may be closely tied to requirements for brood rearing habitat. Molting, non-breeding or unsuccessful breeding geese also used forest habitat freely and avoided observers by fleeing into the forest. Use of habitat compared to tide stage was significant (P < .0001) and may be a function of availability. Habitat use compared to daily time periods appeared to reflect feeding activity peaks in early morning and late afternoon. Adult geese primarily used the intertidal zone during pre-incubation; the grassy intertidal zone was used more during incubation and post-incubation. Skunk cabbage (Lysichiton americanum) comprised 23.8% aggregate of foods utilized and appeared to be the most important food during brood rearing. Goslings and molting geese also utilized sea lettuce (Ulva spp.) and blueberry (Yaccinium spp.) berries. Plant matter comprised the bulk of food items.
