Morphological Variation In Stenoderma Rufum, J, Knox Jones Jr., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

For more than 100 years, the red fruit-eating bat, Stenoderma rufum Desmarest, 1820, was known only by a specimen of unknown geographic provenience. Anthony ( 1918, 1925) rediscovered Stenoderma in Puerto Rican cave deposits, but the first living specimens to be reported since the original description were taken on St. John in the Virgin Islands (Hall and Bee, 1960). Subsequently, Tamsitt and Valdivieso (1966) recorded living representatives from Puerto Rico-from a population later named and described as a distinctive subspecies, Stenoderma rufum darioi, by Hall and Tamsitt (1968). The latter authors also reported a specimen of S. r. rufum …

Impoundment Effects On Water Quality As Reflected In Parasitism Of Reservoir Basses, David A. Becker

Technical Reports

Our aquatic environments are rapidly becoming useless as natural resources through pollution from various sources. It is therefore necessary for us to further understand the various means which relate to this process. The interrelationships between the physico-chemical and biological water qualities undergo marked changes during the ageing of a reservoir. Eutrophication of these impoundments render them rela-tively useless as natural resources. It thus becomes apparent that we must gain further knowledge of these processes if we are to devise methods for proper reservoir management.

Evolution Of The Iguanine Lizards (Sauria, Iguanidae) As Determined By Osteological And Myological Characters, David F. Avery, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The problem of phylogenic relationships within the iguanine phyletic line and the Madagascar iguanids have been investigated in order to explain the discontinuous distribution exhibited by the members of the family Iguanidae. Owing to inconclusive results from cytology and histological methods, the comparative morphology of the anterior osteology, myology, tongues, and hemipenes were used to determine relationships.

An examination of the above structures of the members of the iguanine phyletic lines and a comparison with the Madagascar iguanids indicates the following: ( 1 ) The Madagascar genera Chalarodon and Oplurus appear to be more closely related to each other than …

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh

Brigham Young University Science Bulletin, Biological Series

This is a review of the use of public lands in Wah Wah and Pine Valleys in western Utah for grazing of livestock, mining, and other private enterprises. The total area of the two valleys is approximately 1,440 square miles of which about 30 square miles are privately owned. From the time grazing of domestic livestock was initiated in the 1870's and 1880's until 1934, the land was free public domain and was grazed on a first-come, first-served basis. Passage of the Taylor Grazing Act in 1934 ended free use of public lands. Existing evidence indicates that by 1934 the …

Bibliography On The Scyphozoa With Selected References On Hydrozoa And Anthozoa, Dale R. Calder, Harold N. Cones, Edwin B. Joseph

Reports

Our goal in assembling this bibliography has been to bring together literature references on all aspects of scyphozoan research. Compilation was begun in 1967 as a card file of references to publications on the Scyphozoa; selected references to hydrozoan and anthozoan studies that were considered relevant to the study of scyphozoans were included. In 1968, a major research program on the jellyfish of Chesapeake Bay was initiated at the Virginia Institute of Marine Science (VIMS) under Dr. E. B. Joseph, and work on the bibliography became an integral part of the program. In 1969 we began converting the bibliography into …

Phosphorescent Animal Forms Of Arkansas, Peggy Rae Dorris

Journal of the Arkansas Academy of Science

Two phosphorescent animal forms, Euryurus sp. and Centruroides vittatus, were collected with a black light in an attempt to collect phosphorescent spiders. Both the millipede and the scorpion were easily observed by the bright phosphorescent yellow color which glowed in the presence of the black light

Bacula Of Some Neotropical Bats, Randall E. Brown, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Neotropical bats representing 56 species of five families were examined for presence or absence of a baculum. Members of the families Noctilionidae and Phyllostomatidae (sensu lato) have no os penis, but the bone was found in all species studied of Emballonuridae, Natalidae, and Vespertilionidae. The bacula of seven emballonurids, one natalid, and seven vespertilionids are briefly described and figured.

The Distribution And Ecology Of The Gammaridea (Crustacea : Amphipoda) Of The Lower Chesapeake Estuaries, James Feely, Marvin L. Wass

Reports

Gammarid amphipods of three tidal rivers entering Chesapeake Bay were studied for ten months, particularly in the York River where 40 species were record during the period. Several species moved up or down the rivers with changing salinity. The more abundant species had longer breeding seasons. The number of described species from lower Chesapeake Bay is now 42 and the presence of 10 undescribed species and of several which bracket the region indicates that much remains to be learned about amphipods in the Bay. Nineteen of these have a boreal affinity and seven are limited to the Virginian subprovince. A …

Hydroids And Hydromedusae Of Southern Chesapeake Bay, Dale Calder

Reports

A survey was made in southern Chesapeake Bay and its tributaries from April 1965 through March 1968 to determine the species of hydrozoans present, their seasonality and reproductive periodicities. This report discusses 43 hydroid and 27 medusa species known from the study area, of which 23 hydroids and 11 medusae have not previously been found in Chesapeake Bay. Clytia paulensis and the hydroid of Moerisia lyonsi have not been reported before in North American waters, and the hydroid of Amphinema dinema is recorded for the first time from the western Atlantic. The present records extend the northern range of one …

Some Biological Aspects Of Lizard Eimerians, With A Description Of Eimeria Poinsettis N. Sp. From Sceloporus Poinsetti, David A, Colwell

All Master's Theses

A previously described eimerian, Eimeria sceloporis, from the northwestern fence lizard, Sceloporus occidentalis occidentalis, was observed for oocyst production, incidence and intensity of infection in both juvenile and adult lizards. In order to test the species specificity of Eimeria ahtanumensis, an attempted transmission was made to Sceloporus poinsetti, Sceloporus jarrovi, Sceloporus undulatus and Sceloporus occidentalis. During the winter of 1970-1971 fecal samples were collected from Sceloporus poinsetti to determine possible coccidial infections. The lizards were collected in September of 1970 in Hidulgo County, New Mexico and the ensuing investigation showed that nine of the thirteen adults were passing an intestinal …

Pseudomonas As Causative Agents Of Fluorescence In Anguispira Kochi (Pfeiffer) Mucus, John Michael Baum

Masters Theses

The mucus from land snail specimens of Anguispira kochi collected from Coles and Edgar counties, Illinois, emits a blue fluorescence when exposed to ultra-violet light. Pseudomonas, a genus of bacteria which produces fluorescent pigments, has been isolated from the mucus of these snails. The object of the study was to compare the fluorescence of the mucus from individuals of A. kochi with the fluorescence of the pigments produced on a synthetic medium by pseudomonads isolated from the mucus of these snails. An effort was made to establish that Pseudomonas is the causative agent of fluorescence in the mucus of …

Reproductive Cycle Of The Male Snapping Turtle, Chelydra Serpentina Serpentina (Linné), Harold Edward Benny

Masters Theses

Thirty-seven male Chelydra s. serpentina were collected from Illinois, Louisiana, Mississippi, Tennessee, and Wisconsin during months of activity from May, 1969 to June 1971. Carapace length for each specimen was measured, and testes and epididymides were dissected out, weighed, measured, fixed, and preserved in Baker's neutral formalin within seven days of capture. Paraffin sections were stained with hematoxylin and eosin. Frozen sections were stained with Sudan IV.

The spermatogenic cycle was similar to those of other Chelonians and reptiles exhibiting post-nuptial spermatogenesis. In Illinois spermatocytogenesis begins in late March or early April. Meiosis is evident throughout May and early June. …

Trap Manifested Behavior Trap Reflected Density Trap Reflected Distribution And Foods Consumed By Raccoons (Procyon Lotor L.) In Two Natural Areas Of Virginia, Elton L. Winslow

Biological Sciences Theses & Dissertations

A study was undertaken comparing populations of raccoons (Procyon lotor L.) in two natural areas of Virginia, one in the Piedmont physiographic province at Montpelier and the other in the coastal plain at Newport News. Comparisons were made with respect to differences in: (1) capture and recapture success, (2) relative trap reflected density, (3) trap reflected distribution with respect to aquatic habitat, and (4) in food consumption. Comparison of capture data indicated that capture success per 100 trap nights was much higher at Newport News (1.58) than at Montpelier (.76). However a similar comparison of recapture success per …
