The Cedar-Sauk Field Station As A Background Site For Urban-Rural Spectral Comparisons Of Direct Beam Solar Radiation In The Visible, Howard A. Bridgman

Field Station Bulletins

The general effects of urban atmospheric pollutants on incoming solar radiation have been observed for many years. Estimates of shortwave depletion usually fall in the 15-20% range (Landsberg, 1956, p. 589), but only a few studies have concentrated on depletion across the spectrum. Such studies have generally been concentrated on absorptive effects of gases in the infrared and the ultraviolet (see Kondratyev, 1969 and Robinson, 1966 for examples). The visible spectrum has largely been ignored. Essential to a study of urban spectral depletion effects is a properly chosen rural background site for comparison purposes, free from urban influences. The results …

Wetlands In Environmental Education, Paul E. Matthiae

Field Station Bulletins

Wetlands are one of the most useful resources the environmentally oriented educator has at his disposal. They are his best teaching facility. Most wetlands allow active use. They provide rapid and easy "direct contact" study of their components. Because one can get an overall perspective, it is often easier to observe the animal populations and to sample the plant communities. Whether the wetland is a wet cattail marsh, sedge meadow, woodland swamp or acid bog the student can see it, feel it and appreciate it as a reservoir for living things. The wetland is not only easy to observe and …

Selected Physical And Chemical Properties Of An Alkaline Bog Lake, Nancy E. Liptak, Margaret Summerfield

Field Station Bulletins

Mud Lake is located in Ozaukee County, Wisconsin, on land adjoining the UW-Milwaukee Field Station. It is surrounded by Cedarburg Bog, the most extensive bog in southeastern Wisconsin. This lake is unusual among bog lakes in being alkaline. Some work has been done on the chemistry of acid bog lakes (Malins Smith, 1942; Gorham, 1956; Gorham and Pearsall, 1956; Hayward, 1957), but none of these authors sampled sites with pH values approximating those of Mud Lake. The primary purpose of this study was to begin a data bank of chemical analyses of Mud Lake water samples. The availability of such …

The Relative Attenuation Of Self-Stimulation, Eating And Drinking Produced By Dopamine-Receptor Blockade, E. T. Rolls, B. J. Rolls, P. H. Kelly, S. G. Shaw, R. J. Wood, Robert H.I. Dale

Scholarship and Professional Work - LAS

Spiroperidol, which blocks dopamine (DA) receptors, attenuated self-stimulation of the nucleus accumbens, septal area, hippocampus, anterior hypothalamus and ventral tegmental area. Dopamine is thus involved in self-stimulation of many sites (in addition to the lateral hypothalamus). The attenuation was not a simple motor impairment of the speed of bar-pressing in that the nucleus accumbens and septal self-stimulation rates were lower than those in treated animals self-stimulating at other sites (Experiment 1). Feeding was partly attenuated, and drinking was much less attenuated by the spiroperidol. Since the rats bar-pressed for brain- stimulation reward, chewed pellets to eat, and licked a tube …

Neolabidophorus Yucatanensis Gen. Et Sp. N. And A New Record For Dermacarus Ornatus Fain, 1967 (Acarina: Glycyphagidae) From Heteromys Gaumeri Allen And Chapman, 1897, Gaumer's Spiny Pocket Mouse (Rodentia: Heteromyidae), Danny B. Pence, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Two species of hypopial nyrnphs of mites of the family Glycyphagidae were recovered from Heteromys gaumeri from Yucatan, Mexico. Numerous specimens of a hypopus identified as Dermacarus ornatus. Fain were recovered from the hair and skin. A single specimen of an endoparasitic hypopus identified as a new genus and species, Neolabidophorus yucatanensis, was recovered from the hair follicles. The new genus differs from similar forms of the subfamily Metalabidophorinae in having a rudimentary clasper organ represented by a median sclerite behind legs IV without external serrated claspers, structure and slightly dorsal position of the tarsal solenidia on legs …

Bats Of Margarita Island, Venezuela, With Zoogeographic Comments, James Dale Smith, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Sixteen species of bats are reported from Margarita Island, Nueva Esparta, Venezuela. These include two species of emballonurids, one noctilionid, two mormoopids, nine phyllostomatids, one vespertilionid, and one molossid. Accounts including natural history and taxonomic comments are given for each species. The chiropteran fauna of Margarita Island is compared with the bat faunas of the adjacent Venezuelan mainland and islands off the northern coast of South America, including Trinidad and other Antillean islands. It is concluded that the chiropteran fauna of Margarita Island represents an attenuated mainland fauna.

Microanatomical Studies Of Dentalium Pilsbryi Rehder, 1942 And D. Texasianum Philippi, 1848, Kenneth R. Bazata

Open Access Master's Theses (through 2010)

In the course of an investigation of the nature of the heart and kidney of D. pilsbryi, the present author discovered an unexpected configuration of the anatomy of the digestive system (Bazata, 1971). The present report represents an extension of this preliminary study and is the first detailed account of the digestive system in D. pilsbryi and D. texasianum. Comparative descriptions of the siphonal complex, the foot, and the histology of the anterior mantle also are given.

Vocalizations In A Population Of Green-Tailed Towhees (Chlorura Chlorura), Timothy Andrus Burr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies of vocalizations in a montane population of Green-Tailed Towhees were conducted during the summer months of 1971 and 1972 in Cache County, Utah. The song and call repertoiries of 10 breeding pairs were recorded and analyzed on a sound spectograph.

Males averaged 8.7 different song and 18.2 different not types. Song variation on the population level is high (58 different songs) but the sharing of these songs among the males is low (22.4). Populational note structure is equally diverse but reveals a greater degree of sharing (75%).

Both males and females used three calls, the meow, tick, …

Annotated Checklist Of Mammals Of The Yucatán Peninsula, México. Ii. Rodentia, J. Knox Jones Jr., Hugh H. Genoways, Timothy E. Lawlor

University of Nebraska State Museum: Mammalogy Papers

The Yucatán Peninsula, as encompassed in this series of papers, includes the Mexican states of Campeche and Yucatán, and the Federal Territory of Quintana Roo. This region is a low-lying plain that rises gently in elevation from north to south. It is surrounded on three sides by water and bounded on the south by British Honduras (i.e. Belize), Guatemala, and the Mexican state of Tabasco. The vegetation of the peninsula increases in height from north to south and from the coast inland. Generally, forest to the north is xerophilic, but that of the southern part of the peninsula is tall, …

A Study Of Aquatic Hyphomycetes Of Southeastern Wisconsin, John W. Baxter, Juanita Bronaugh

Field Station Bulletins

This paper presents a portion of the results of a distributional and ecological study of aquatic Hyphomycetes in seven counties of southeastern Wisconsin. Results of the water chemistry studies and laboratory studies on the physiology of these fungi will be published separately in Mycopathologia et Mycologia Applicata. Part of this research was supported by a grant from the Graduate Faculty Research Committee. In the present investigation 28 species, representing 21 genera, were found growing on submerged decaying leaves in streams, lakes and bogs. Three previously undescribed species were found as loose spores in foam samples from Cedar Creek and Sauk …

Dispersal Movements Of Juvenile Black-Capped Chickadees, John R. Meyer, Charles M. Weise

Field Station Bulletins

To learn more about Chickadee dispersal this study was undertaken from the summer of 1970 through the summer of 1973, involving the color-banded population of Black-capped Chickadees at the UW-M Cedar-Sauk Field Station described by Weise (1971). The most intensively studied birds were located in about 26 hectares of upland beech-maple forest and about 30 hectares of the cedar-tamarack bog forest at and immediately surrounding the Field Station. The territories of the breeding pairs in these areas were mapped, and as many nests as possible were located. The development of the young in accessible nests was followed, and just before …

A Taxonomic Study Of The Western Collared Lizards, Crotaphytus Collaris And Crotaphytus Insularis, Nathan M. Smith, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The heterogeneous nature of the collared lizards west of the Colorado River prompted this study. Samples from known populations of C. c. auriceps, C. c. baileyi, and C. c. fruscus were used as a base for defining the western populations. External morphology and cranial morphology were compared by cluster, canonical, and discriminant analyses.

Results of these analyses show a western complex of four populations which are distinct from the three base populations of the collaris complex. Members within the western complex are distinguishable with at least 90 percent reliability by discriminant analysis. Because of intergradation patterns seen in western Sonora, …
