Taxonomic Survey Of The Eggs And Larvae Of Some Species Of Utah Amphibia, Don B. Skousen
Taxonomic Survey Of The Eggs And Larvae Of Some Species Of Utah Amphibia, Don B. Skousen
Theses and Dissertations
How the eggs and larbae of the Utah amphibians differ from each other is the problem to be considered in this paper. Certain problems are yet to be answered. One problem is that the larvae of Rana pretiosa subsp. From utah fit the description of the Nevada form, Rana pretiosa luteiventris, as described by Thompson (1913) and not the description of Rana pretiosa pretiosa as set forth by Svihla (1935). Another problem is that the adults, tadpoles, and eggs of Rana pipiens brachycephala and Rana onca are strikingly similar. Rana fisheri of the Las Vegas Valley in nevada and Rana …

A Study Of The Fleshy Fungi Of Utah, Kent Howell Mcknight
Theses and Dissertations
It is the purpose of this study to further the ends of Mycology by presenting the fleshy fungi which are known to grow in Utah. The term fleshy fungi as used here shall include those Ascomycetes and Basidiomycetes which produce large or otherwise conspicuous sporocarps and their closely related forms. This includes portions of the sub-classes Pyrenomycetes and Discomycetes of the Ascomycetes; and portions of the Heterobasidiao and Eubasidiae of the Basidiomycetes (4). The sporocarps may be fleshy, woody, papery, leathery, carbonous or waxy in texture. This would exclude the Myxomycetes. However, since there have been no extensive studies of …
The Taxonomy Of Utah Orthoptera With Notes On Distribution, Andrew H. Barnum
The Taxonomy Of Utah Orthoptera With Notes On Distribution, Andrew H. Barnum
Theses and Dissertations
To an entomologist, the Orthoptera1 is in a state of confusion with respect to the available literature. Work has been done, and is now being done on the orthopteran fauna, but manuals tor identification of most species are not available for all sections or the country. Exclusive of a few lim-ited groups, Utah is among the areas that has no complete keys for taxonomic workers. In biological ivenstigations identification is essential: The species being studied must be definitely known. The primary purpose of this study, therefore, is to list the Utah Orthoptera and provide the keys necessary to their critical …
