"1984 Christmas Count," From Nebraska Bird Review (March 1985) 53(1).

Nebraska Bird Review

Ninety-nine species (seven more than last year) were reported on the 1984 Christmas Count, and two species (compared to three last year) were reported as present during the count period but not recorded on the count day on any count. The same eight localities reported in both years. Eighteen species were reported on all counts this year, compared to thirteen last year. The total individual count this year was 345,052; in 1983 it was 43,652, but in 1982 it was 302,646. Almost 74% of this year's count was due to the concentration of Red-wings in Omaha; in 1982 the high …

Three Species Of Siberian Geese Seen In Nebraska, Rick Wright, Alan Grenon

Nebraska Bird Review

At about 3:00 PM on 29 December 1984, while participating in the DeSoto NWR Christmas Count, Betty Grenon, David Starr, and the authors, Rick Wright and Alan Grenon, flushed from near the west shore of the DeSoto Cut-off (Washington County, Nebraska) a party of seven Greater White-fronted Geese. With these seven geese was one distinctly larger, which drew our attention as the small flock flew above us for about five minutes. The larger bird displayed obvious damage to or loss of primaries on each wing, making it easier for the four of us to concentrate our observations on it and …

Spatial Patterns Of Plant Communities And Differential Weathering In Navajo National Monument, Arizona, Jack D. Brotherson, William E. Evenson, Samuel R. Rushforth, John Fairchild, Jeffrey R. Johansen

Great Basin Naturalist

Vegetation patterns in Navajo National Monument, Arizona, were studied over a five-year period from 1977 to 1981. Twelve distinct plant community types occur within the boundaries of the park. These communities are characterized and the dominant plant species of each are recorded. The relationships of parent material, soils, and moisture to plant communities are also discussed. It appears that discrete communities occupy soils of different characteristics, particularly with respect to amount of weathering of parent material.

Tracking Mammals With Fluorescent Pigments: A New Technique, Cliff A. Lemen, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

We have developed a new technique for following the movement of small mammals at night. It entails the use of fluorescent pigments and ultraviolet light. This method allows one to gather extremely accurate information on the location of animals and to trace the movement of individuals for up to 900 m. For much of this distance a detailed record is left by the trail of pigment. It can then be determined which objects are manipulated, what plants are climbed, what burrows are entered and which items are eaten. The use of fluorescent pigments to track animals has two other major …

Gametogenesis En Chthonerpeton Indistinctum (Gymnophiona: Typhlonectidae), Rafael O. De Sá, Nibia Berois

Biology Faculty Publications

RESUMEN:

Histológicamente, las gónadas de Chthonerpeton indistinctum son similares a las ya descritas para otras especies del orden Gymnophiona. Los lóbulos testiculares se hallan compartimentados en unidades estructurales denominadas lóculos. La espermatogénesis ocurre en cistos sincrónicos de células germinales. Durante la espermiogénesis se identifican cuatro estados consecutivos de desarrollo: 1) cistos de espermátidas redondeadas; 2) cistos de espermátidas arrifionadas; 3) cistos de espermátidas bastoniformes y 4) espermátidas en ramillete.

El análisis histológico de los ovarios mostró la presencia de tres estados en la maduración de los folículos ováricos. Estas etapas pueden ser identificadas de acuerdo a: 1) ubicación del folículo …

Community Ecology, Robert K. Rose, Elmer C. Birney

Biological Sciences Faculty Publications

COMMUNITIES with Microtus tend to be structurally simple, usually grasslands or tundra, and to have no more than two species of Microtus and rarely more than six species of small mammals. Microtus often dominates both numerically and in total small mammal biomass, especially at higher latitudes. The small mammal community is most influenced by Microtus through its fluctuations in density, and thus also in biomass, by its relatively high level of diurnal activity, and by its year-round activity. Other species of small mammals may be adversely affected because Microtus usually is larger and behaviorally dominant and also because the mere …

Analysis Of Arkansas Fur Harvest Records - 1942-1984: Ii. Species Accounts, James H. Peck, Joseph D. Clark, Tiny Sheldon, Gary A. Heidt

Journal of the Arkansas Academy of Science

Fur harvest records were maintained by the Arkansas Game and Fish Commission on the following 16 furbearers: badger, beaver, bobcat, eastern spotted skunk (civet), coyote, gray fox, long-tailed weasel, mink, muskrat, nutria, opossum, raccoon, red fox, red wolf, river otter, and striped skunk. These harvest records were analyzed for each species in terms of mean pelt price and numbers of pelt sold by region (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta) per year. Historical or biological influences important in interpreting species accounts are presented.

Analysis Of Arkansas Fur Harvest Records - 1942-1984: Iii. Harvest-Price Relationships, Joseph D. Clark, Gary A. Heidt, Tina Sheldon, James H. Peck

Journal of the Arkansas Academy of Science

Correlation and linear regression analyses between mean annual pelt price and total harvest of 13 Arkansas furbearer species between 1965 and 1983 were performed for state and regions (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta). Statewide, strong correlations (r > 0.80) were identified for bobcat (Felis rufus), coyote (Canis latrans), gray fox (Urocyon cinereoargenteus), mink (Mustela vison), nutria (Myocastor coypus), opossum (Didelphis virginiana), and raccoon (Procyonlotor). Moderate correlations (r = 0.55 - 0.79) were identified for eastern spotted skunk (Spilogale putorius), muskrat (Ondatra zibethicus), river otter (Lutra canadensis), and striped skunk (Mephitis mephitis). Nonsignificant correlations (r < 0.468) were shown for beaver (Castor canadensis) and long-tailed weasel (Mustela frenata). Regional differences were noted for each species.

Mammals At Hidden Springs State Forest, Shelby County, Illinois, Leslie L. Clapp

Masters Theses

A survey of the mammals at Hidden Springs State Forest (HSSF) in Shelby County, Illinois was conducted from May 1 to November 18, 1984. The survey was designed to determine the species and relative abundance of mammals associated with major habitat types of the Forest based on area walk-through surveys, streamside surveys, mist net surveys, snaptrap/pitfall surveys, and a hunter questionaire. A total of 26 mammal species were found associated with various habitats within the Forest and an additional four species were reported within Shelby County. One species, the southeastern shrew (Sorex longirostris) had not previously been reported …

Introduction To Species Of Special Concern In Pennsylvania, Chapter 6--Mammals, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

First two paragraphs:

The mammals in Pennsylvania have long been under the management authority of the Pennsylvania Game Commission, but it was not until 1978 that an effort was made to deal with threatened and endangered mammals in the Commonwealth. At this time, Michael J. Puglisi was appointed as Coordinator for the Threatened and Endangered Species Program within the Game Commission. In late February 1979, Mr. Puglisi asked Hugh H. Genoways to chair an informal study group on endangered mammals in Pennsylvania. The immediate concern of this group was to be the development of a list of threatened and endangered …

Distribution, Habitat, And Status Of The Gilt Darter (Percina Evides) In Minnesota, J. T. Hatch

Journal of the Minnesota Academy of Science

The distribution and habitat of gilt darter (Percina evides) populations in Minnesota were studied from 1977 through 1983. Gilt darters occurred only in the St. Croix River drainage in moderate to large rivers or near the mouths of large streams. In the late spring, gilt darters were found most often in cobble raceways of moderate to swift current, where they later spawned. Young-of-the-year occupied this same habitat until early fall, when they and the adults moved to deep, swift chutes of rubble riffles to overwinter. Gilt darters tended to associate with the deeper, swifter portions of raceways and riffles, and …

Comparative Study Of Lactate Dehydrogenase Activity In Diving And Nondiving Reptiles, Dennis A. Baeyens, Deborah Bursey, Robert Rountree

Journal of the Arkansas Academy of Science

The properties of lactate dehydrogenase (LDH) were examined in two snake species and one turtle species. The snakes used in the study were the semi-aquatic Nerodia rhombifera and the terrestrial Elaphe obsoleta, while Pseudemys scripta represented the turtle species. Our purpose was to compare the LDH activity of nondiving reptiles (Nerodia and Elaphe) with that of the well established diver Pseudemys. The kinetic properties of LDH and its susceptibility to inhibition by elevated pyruvate concentrations were investigated in the brain and heart of the three species. Brain and heart were chosen because they are highly aerobic tissues and therefore should …

Analysis Of Arkansas Fur Harvest Records - 1942-1984: I. State And Regional Accounts, Gary A. Heidt, James H. Peck, Tiny Sheldon, Joseph D. Clark

Journal of the Arkansas Academy of Science

Fur harvest records maintained by the Arkansas Game and Fish Commission from 1942-1984 summarized the number of pelts sold by region (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta) and the average price per pelt for 16 furbearers. Analysis of these records showed that in the 1979-80 trapping season (the record year for both harvest and value both in Arkansas and the nation), the value of the Arkansas fur harvest ranked 14th nationally (2.12% of total national value). Fur harvests in Arkansas were high in the 1940's, declined in the 1950's and 1960's and then experienced a rapid …

Age And Growth Of The Bluegill Lepomis Macrochrius Rafinesque From An Unmanaged Watershed Lake In Northeast Arkansas With Observations On Lake Ecology, Stephen A. Sewell

Journal of the Arkansas Academy of Science

Age and growth data were compiled on 114 bluegill, Lepomis macrochirus Rafinesque, taken from floodwater retarding structure #15 of the Big Creek Watershed project in Craighead and Greene counties of northeast Arkansas. This project was completed in the early 1960's by USDA-SCS. The 73 surface acre lake has not been managed for fish production and has been subjected to unscheduled water level manipulations during dry weather periods. These manipulations have maintained the bluegill population in healthy condition. The oldest bluegill collected were age class IV+. Average condition coefficient K(TL)declined from oldest to youngest individuals (2.96 in age class IV+ - …

Morfología Y Funciones Del Conducto De Müller De Chthonerpeton Indistinctum (Reinhardt Y Lutken, 1862) (Amphibia: Gymnophiona) En Relación Con Los Mecanismos Reproductivos De La Especie, Nibia Berois, Rafael O. De Sá

Biology Faculty Publications

El orden Gymnophiona comprende anfibios ápodos, ciegos, de hábitos cavícolas y acuáticos. Como consecuencia de estos hábitos resulta muy difícil su colecta, lo cual redunda en un escaso conocimiento de la biología del orden y sobre las relaciones filogenéticas del mismo.

Una de las características más particulares del grupo se refiere a la modalidad reproductora, ya que aproximadamente el 50% de las especies presentan viviparidad y la totalidad de ellas tienen fecundación interna. Es por esta razón que el estudio del aparato reproductor ha sido encarado por diversos autores, en especial por Wake (1968, J. Morphol. 126: 291) con una …

Corticocortical Projections Of A Visually Responsive Area In The Cat Brain, Joseph Mcgrath

Journal of the Arkansas Academy of Science

The Clare-Bishop (CB) area bears the name of the investigators who first (1954) demonstrated a cortical area in the cat brain located along the lateral aspect of the middle suprasylvian gyrus which responded electrophysiologically to both optic nerve and striate cortex (area 17) stimulation. More recent studies of CB or the lateral suprasylvian (LS) area have supported its role in visual and/or oculomotor functions. Silver degeneration methods were undertaken to clarify some of the corticocortical connections of this cortical region. The data accumulated provides a morphological basis in support of the CB area's role in visual and/or oculomotor activities

Role Of Centriolar Matrix And Striated Rootlets In Centriolar Pairing And Orientation During Spermatogenesis In Hydractina Echinata, Maurice G. Kleve

Journal of the Arkansas Academy of Science

Transmission electron microscopy of the spermatogenic stages of the hydroid, Hydractinia echinata, reveals a series of complex structural and positional changes in the centrioles of spermatocytes and spermatids. The newly generated centriolar pairs of spermatocytes form an unusual four-centriole aggregate that persists until cell division. The distal centrioles of this aggregate are shrouded with a very dense matrix that accumulates after centriolar replication. This matrix facilitates the mechanical attachment between distal centrioles and microtubular nucleating satellites, striated rootlets and pericentriolar processes. The association of these accessory structures occurs sequentially and is repeated in spermatocytes and spermatids. An electron dense plaque, …
