A Taxonomic Investigation Of Some Rhizomatous Species Of The Genus Muhlenbergia (Gramineal)., James Kurtz May 1976

A Taxonomic Investigation Of Some Rhizomatous Species Of The Genus Muhlenbergia (Gramineal)., James Kurtz

Student Work

Introduction: The genus Mulenbergia, usually placed in the subfamily Eragrostoideae (Stebbins and Crampton, 1961; Gould, 1975) is a large, widely distributed, group of grasses, encompassing numerous species and various growth forms. The subgenus Muhlenbergia, comprised of mesic, broad-leaved, usually rhizomatous species, can easily be separated from the rest of the genus on the basis of growth habit and habitat preferences (Pohl, 1969). Species of the subgenus are widely distributed in North America but are most abundant in the deciduous forest of the eastern part of the continent.


The Effects Of Grazing Management On Small Mammal Density And Diversity In Nebraska Sandhills., Michael C. Schrad Apr 1976

The Effects Of Grazing Management On Small Mammal Density And Diversity In Nebraska Sandhills., Michael C. Schrad

Student Work

Introduction: Strong relationships exist between vegetative structure and composition of grassland and the animal composition in terms of density and diversity (MacArthur 1961, Wiens 1973). Recent investigations of grassland habitat management and its effect on the avifauna, indicate that the primary mechanism of habitat alteration of a mixed or short grass prairie is grazing (Owens and Myres 1973; Balda 1975; Wiens and Dyer 1975).

An Electron Microscopic Study Of Microbody Types Found In Dwarf Pea Internode., Charles Thomas Bringle Nov 1975

An Electron Microscopic Study Of Microbody Types Found In Dwarf Pea Internode., Charles Thomas Bringle

Student Work

Introduction: Ever since plant cell organelles morphologically resembling animal microbodies were clearly established by Mollenhauer et al. (1966) and Frederick et al. (1968), a great deal of attention has been focused, on this subject. Several papers outlining morphology and orientation have followed (Frederick and Newcomb, 1968, 1969; Vigil, 1971, 1973a). Plant microbodies appear to be a distinct class of organelle found ubiquitously in cells. They are single membrane-bounded and have a dimensional range of 0.2u - 0.5u. Their interior exhibits a coarse to finely granular matrix and often a para-crystalline or nucleoid structure is quite evident. Microbodies are characteristically associated …
