Seasonal Variation In The Tubular And Interstitial Areas Of The Testes In Sternotherus Odoratus L., Robert Hans Spaet

Masters Theses

Seasonal changes within the tubular and interstitial areas of the testes in Sternotherus odoratus are investigated, histologically and histochemically. Forty specimens were collected in Illinois, Tennessee and Louisiana between May, 1969 and August, 1972.

Many of the histological and macroscopic observations made by Risley (1938) on the spermatogenic cycle of S. odoratus in Michigan are confirmed. Contrary to his findings, fluctuations in interstitial cell nuclear diameters are observed during spermatogenesis. Greatest diameters coincide with what Risley has considered " . . . period of most active breeding." Sertoli cell nuclear diameters undergo similar fluctuations being greatest during spring breeding and …

Critical Flicker Frequency In A Harp Seal, Pagophilus Groenlandicus (Erxleben, 1777), Charles D. Bernholz

University of Nebraska-Lincoln Libraries: Faculty Publications

Critical flicker frequency (CFF) in a free-swimming harp seal (Pagophilus groenlandicus) was investigated using behavioral techniques. The resulting CFF versus intensity contour indicates a definite rod-cone break, confirming a duplex photoreceptor population whose presence had not been observed in previous morphological reports.

Two Species Of Bats New To The Fauna Of Trinidad, Hugh H. Genoways, Robert J. Baker, R. S. Loregnard

University of Nebraska State Museum: Mammalogy Papers

Goodwin and Greenhall (1961) in their monograph of the bats of Trinidad and Tobago recorded 58 species of chiropterans from the island of Trinidad. In two subsequent publications (Goodwin and Greenhall, 1962, 1964) these authors recorded Mesophylla macconnelli, Prornops nasutus, and Phylloderma stenops from Trinidad bringing the number of species known from the island to 61. In August 1967, one of us (R. J. Baker) and Larry Deaven netted bats on Trinidad in connection with ongoing studies of chiropteran karyology, and obtained two species not previously recorded.

Bats Of Jalisco, México, Larry C. Watkins, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The fauna and flora of the Mexican state of Jalisco have received the much deserved attention of a number of biologists in recent years. Nevertheless, few comprehensive accounts of the biota of this interesting and physiographically diverse area have been published. In the period from 1949 to 1969, field representatives of the Museum of Natural History at the University of Kansas collected vertebrates in Jalisco. Among the specimens obtained from the state, the mammalian fauna of which never has been treated as a unit previously, were approximately 3000 bats, which form the primary basis for this report. In addition to …

Mammals From Southwestern North Dakota, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

The distribution of the mammals in the southwestern part of North Dakota and their ecological and taxonomic relationships have not been well documented. In addition to Vernon Bailey's (1927) survey of mammals of the state, based primarily upon field work conducted between 1912 and 1916, the only other principal studies dealing with the mammalian fauna of southwestern North Dakota were a preliminary report of the mammals of the state by Bailey et al. (1914) and the publication by J.A. Allen (1875) on mammals taken by the expedition that surveyed a route for the North Pacific Railway. Our studies, which were …

Forty-three species of fleas were collected in Venezuela by personnel of the Smithsonian Venezuelan Project. Currently there are fifty-two species of fleas known from Venezuela. Four new taxa are described: Hormopsylla cryptica, Ctenidiosomus perplexus, Adoratopsylla antiquorum rara and Adoratopsylla antiquorum recta. The females of Adoratopsylla antiquorum discreta Jordan and Rothschildopsylla noctilionis (Costa Lima) are described.
