Venezuelan Nycteribiid Batflies (Diptera: Nycteribiidae), Lindolpho R. Guimarães Sep 1972

Venezuelan Nycteribiid Batflies (Diptera: Nycteribiidae), Lindolpho R. Guimarães

Brigham Young University Science Bulletin, Biological Series

Eleven species of Nycteribiidae, all belonging to the genus Basilia, are reported from Venezuela. Of these, two (tuttlei and typhlops) are described as new and four (anomala, dubia, juquiensis, and tiptoni) are recorded for the first time. B. anomala is the first species with three tergal plates to be found in South America. Synonymies, previous localities, and host records are given for all species, as well as new records and comments. Geographical distribution and host-parasite associations are discussed. Field parties of the Smithsonian Venezuelan Project obtained the material on which this paper is based.

The Hyobranchium And Throat Myology Of The Adult Ambystomidae Of The United States And Northern Mexico, John E. Krogh, Wilmer W. Tanner May 1972

The Hyobranchium And Throat Myology Of The Adult Ambystomidae Of The United States And Northern Mexico, John E. Krogh, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The 16 species and subspecies of the Ambystomidae of the United States are placed into six groups according to their throat morphology as follows: The Dicamptodon group, the Rhyacotriton group, the A. Annulatum–A. cingulatum group, the A. gracile-A. jeffersonianum-A. mabeei-A. macrodactylum-A. maculatum group, the A. talpoideum group, the A. opacum-A. texanum group, and the A. rosaceum-A. t. tigrinum-A. t. melanostictum-A. t. nebulosum group. Dicamptodon appears to be the most primitive group and Rhyacotriton the most specialized. Based on the morphology of the throat region it is suggested that A. rosaceum be placed in the tiger salamander group as a subspecies …

Understory Characteristics Related To Site Quality For Aspen In Utah, James H. Warner, Kimball T. Harper Apr 1972

Understory Characteristics Related To Site Quality For Aspen In Utah, James H. Warner, Kimball T. Harper

Brigham Young University Science Bulletin, Biological Series

An analysis has been made of the basic ecology of aspen forests of the mountainous areas of Utah and northern Arizona. Forty-nine study areas have been examined in respect to density, height and age of the tree cover, tree reproduction, and composition and biomass production of the understory. A graphic model of interspecific assocations among prevalent understory species has been prepared by a cluster-analysis procedure based on presence and absence of species in 1,225 small quadrats (0.25 m2) uniformly distributed among the 49 stands. The model separates species of relatively stable as opposed to rapidly seral aspen forests. …

A Flora From The Dakota Sandstone Formation (Cenomanian) Near Westwater, Grand County, Utah, Samuel R. Rushforth Sep 1971

A Flora From The Dakota Sandstone Formation (Cenomanian) Near Westwater, Grand County, Utah, Samuel R. Rushforth

Brigham Young University Science Bulletin, Biological Series

A Cretaceous (Cenomanian) flora from the Dakota Sandstone Formation near Westwater, Grand County, Utah contains an admixture of ferns and angiosperms. The ferns of this flora are representative of an older Jurassic-Wealden vegetational type, whereas the angiosperms are typical of the modern vegetational type. Species of Gleichenia and Matonidium and Astralopteris coloradica represent the dominant forms in this flora.

The Westwater flora contains fourteen genera including nineteen species and one variety. New species described from this flora include Asplenium dakotensis, Coniopteris westwaterensis and Ilex serrata.
