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.

Mites Of The Family Laelapidae In Venezuela (Acarina: Laelapidae), Deane P. Furman
Brigham Young University Science Bulletin, Biological Series
This publication presents the results of an extensive survey of symbiotic laelapid mites of vertebrates from Venezuela. Over 40,000 vertebrates were examined from a wide variety of life zones and localities. The laelapid fauna represented includes 1 new genus, Hymenolaelpas, and 7 genera previously described: Laelaps, Mysolaelaps, Tur, Steptolaelaps, Neoparalaelaps, Gigantolaelaps, and Androlaelaps. The genera are represented by 51 species and subspecies, of which 8 are described as new. Previously unknown males and immatures of several species are described. Gigantolaelaps versteegi ( Oudemans ) is redescribed from type material; G. wolffsohni (Oudemans) is redescribed from Oudemans’ original material; G. peruviana …

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