Notes On Bird Sightings In Nebraska

Nebraska Bird Review

Ross' Goose. A single bird came to Heartwell Lake (in the Hastings area) in mid-December 1995 and has been here up to now (4 April 1996). It is not injured and flies well, but it has chosen to stay because Hastings uses a device to keep the water open. I threw food out especially to the little goose because the larger domestic ducks chase it away. It is so used to me by now that it will come to within 12-15 feet of me. I walk to the lake nearly every day, and the wild Mallards, Lesser Scaups, Ringnecked …

Winter Field Report, December-February 1995-96, W. Ross Silcock

Nebraska Bird Review

As far as the birds are concerned, this was an uneventful winter, with only a few rarities. Highlights include the second pile-up of rare gulls at L. McConaughy, and a Common Redpoll influx. Best of the rarities (all subject to Records committee scrutiny and pending its acceptance) were a 5th record Red-necked Grebe at L. McConaughy; a first-record Mew Gull at L. McConaughy; Iceland, Lesser Black-backed, and Great Black-backed Gulls at L. McConaughy; a Cassin’s Finch at Crawford; White-winged Crossbills at Norfolk and North Platte; and a Hoary Redpoll at Wakefield. Out-of-season reports were record-early Blue-winged Teal in Dixon Co, …

First Record Of Glaucous-Winged Gull For Nebraska, Don Roberson, Rita Carratello

Nebraska Bird Review

During Easter vacation in 1995, we visited the Western Great Plains in search of dancing prairie-chickens and grouse. We started in southeastern Colorado and planned on driving to the Bessey Division, Nebraska National Forest, where we had reservations at photo blinds. But at dawn on 10 April, a huge blizzard began howling and worsened during the drive through Kansas. By the time we reached western Nebraska, our excursion stalled at Ogallala when interstate 80 was closed due to high winds and snow. It was becoming apparent that we would not make it to our planned destination.

Homing Behavior And Orientation In The Gopher Tortoise, Gopherus Polyphemus, Kevin Michael Connor

USF Tampa Graduate Theses and Dissertations

Gopher tortoises are found in xeric habitats in the southeastern United States. In these xeric habitats, gopher tortoises excavate and reside in burrows which provide shelter and protection. Gopher tortoises are active throughout the year, often making several journeys a day away from their burrows. Although they may move substantial distances, they return to their burrows, suggesting that they posses a well-developed orientation and homing ability. This study investigated the ability of gopher tortoises to home from short distance (40 meters, just outside of or on the perimeter of their home ranges) and intermediate distances (200 meters, approximately 2 home …

Ecology And Community Relationships Of The River Cooter, Pseudemys Concinna In A Southern Illinois Backwater, Michael J. Dreslik

Masters Theses

In Illinois the River cooter, Pseudemys concinna, is an enigmatic endangered species. Even throughout its range, ecological studies on the River cooter are rare. During 1994 and 1995 I quantified the: growth rates and trends, population size and structure and dietary habits of a population from floodplain lake in Gallatin county, Illinois. Population estimation (Schnabel method) predicted 136 individuals at a density of 4.6 turtles/ha with a biomass of 3.6 Kg/ha. The sex ratio is slightly male biased (1:1.14). From back-calculated growth data, the von Bertalanffy growth model (Fabens' method) estimates males with a higher growth rate (k) and …

A New Species Of The Genus Rhogeessa, With Comments On Geographic Distribution And Speciation In The Genus, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A new species of Rhogeessa is described from southern Suriname. The new species is characterized by a karyotype that possesses a diploid number of 52 and a fundamental number of 52 and by its relatively large overall size compared to other South American Rhogeessa. Tenspecies are now recognized within the genus. Seven of these species, including the one described herein, are members of R. tumida complex. Two of these species--R. io and R. minutilla--also occur in South America and the remaining four species are confined to Mexico and Central America.

Communities Of Cloacal Bacteria In Tree Swallow Families, Michael P. Lombardo, Patrick A. Thorpe, R. Cichewicz, M. Henshaw, C. Millard, C. Steen, T. K. Zeller

Peer Reviewed Publications

Our aim in this study was to survey the communities of bacteria found in the cloacae of adult and nestling Tree Swallows (Tachycineta bicolor), determine if there were familial patterns of prevalence, and determine if there were relationships between bacteria loads and nestling size when 12 days old and fledging success.

Identification Of Walleye X Sauger Hybrid By Isozyme Electrophoresis, J. E. Fulton, J. S. Otis, K. S. Guise

Journal of the Minnesota Academy of Science

Of 125 phenotypic walleye screened by isozyme electrophoresis, one unusual individual was detected and subsequently suspected of being a walleye (Stizostedion vitreum vitreum) x sauger (S. canadense) hybrid. The isozyme pattern obtained for L-iditol dehydrogenase (IDDH, E.C. 1.1.1.14), phosphoglucomutase (PGM, E.C. 5.4.2.2) and a fast migrating aspartate aminotransferase (AAT, E.C. 2.6.1.1) isozyme showed that this individual had both walleye and sauger isozymes. Isozyme analyses is a useful technique for distinguishing walleye x sauger hybrids from parent species. This is the first report of alleles of the AAT* locus being species specific for sauger and walleye, and the first confirmed report …

Distribution Of Baird's Pocket Gopher (Geomys Breviceps) In Arkansas; With Additional County Records, Douglas A. Elrod, Gary A. Heidt, Mark R. Ingraham, Earl G. Zimmerman

Journal of the Arkansas Academy of Science

Recently, a population of pocket gophers in the north-central portion of Arkansas was determined to be the plains pocket gopher (Geomys Imrsarius), rather than Baird's pocket gopher (Geomys breviceps). This changed the known range of both species extensively. A detailed examination of the known range of Baird's pocket gophers (G. breviceps) in Arkansas resulted in 12 new county records. Biogeographically, G. breviceps appears to be found in all physiographic regions within the state with the possible exception ofCrowley's ridge. It is most common in the Gulf Coastal Plain and rarest in the Mississippi Alluvial Plain. The distribution ofG. breviceps is …

Functional Responses Of Iphiseius Degenerans And Neoseiulus Teke (Acari: Phytoseiidae) To Changes In The Density Of The Cassava Green Mite, Mononychellus Tanajoa (Acari: Tetranychidae), F. E. Nwilene, G. Nachman

All Peer-Reviewed Publications

The functional responses of pintonymph and adult female Iphiseius degenerans and Neoseiulus teke to increasing density of three stages of their prey, the cassava green mite (CGM), Mononychellus tanajoa, were studied on excised cassava leaf discs under laboratory conditions. The responses obtained were predominantly sigmoid type III curves with the highest plateau when both stages of I. degenerans and N. teke were preying on CGM eggs. In all cases, the predation rate of the former species exceeded that of the latter. The empirical data were fitted by four different models. From the models, the attack coefficient (a') and handling time …

Captive Environmental Influences On Behavior In Zoo Drills And Mandrills (Mandrillus), A Threatened Genus Of Primate, Erik Terdal

Dissertations and Theses

Drills (Mandrillus leucophaeus) are an endangered species of African monkey (Cercopithecidae), and their sole congener the mandrill (Mandrillus sphinx) is vulnerable to extinction. Both species are threatened in the wild by deforestation and hunting.

Drills have a poor record of captive reproduction. Many individuals appear to have behavioral deficiencies which interfere with reproduction. Thus, the zoo population of drills does not serve as a “hedge” against the species’ total extinction: drills are endangered in captivity as well as in the wild. Mandrills, by contrast, reproduce well in captivity. Information on the behavior of mandrills in captivity may help zoo managers …

Microhabitat Use By Gilbert's Potoroo (Potorous Tridactylus Gilbertii Gould) In Relation To Vegetation Associations And Ground Cover, S. Vetten

Theses : Honours

Gilbert's potoroo has been rediscovered 120 years after it was believed to have become extinct. In 1994 the presence of Gilbert's potoroo was confirmed at Two Peoples Bay Nature Reserve, near Albany, and since that time the need for a detailed understanding of the biology and behaviour of the species has become urgent. An understanding of the habitat requirements of the species will aid in its recovery from its present critically endangered status and will act as a guide for future management decisions concerning translocations of new populations into other areas. The present study was conducted at Two Peoples Bay …

Biogeography Of Arkansas Mammals With Notes On Species Of Questionable Status, Gary A. Heidt, Douglas A. Elrod, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Seventy-one native or re-introduced species of mammals were analyzed with respect to their geographical distributions and relationships to the four broad physiographical regions of Arkansas. Mammalian diversity in the Ozark Mountains, Ouachita Mountains/ Arkansas River Valley, Gulf Coastal Plain, and Mississippi Alluvial Plain/Crowley's Ridge was not area dependent. The majority of mammalian species (44) occurs statewide with the greatest diversity in the interior highland regions. The Ozark Mountains contain the most species endemic to an area. Thirteen species which are of questionable status in Arkansas are discussed. The presence of the plains pocket gopher (Geomys bursarius), a second species of …

First paragraph of the introduction:

La obtención de parásitos de mamíferos que son colectados durante las investigaciones o bio-inventarios toma mucho tiempo; y en el pasado, estas colectas ráramente se realizaban. De cualquier forma, los parásitos y otros simbiotas forman un componente importante de las características biologicas y ecologicas de los hospederos y deben ser muestreados. Por ejemplo, trabajos recientes en la diversidad parasitaria y la biogeografía en mamíferos de Bolivia por Gardner y Duszynski (1990), Gardner (1991), y Gardner y Campbell (1992 a,b) no hubiera popdido realizarse sin el trabajo de colección apropiado de la fauna parasitaria/simbiótica de los …

In July 1995, we visited two of the three previously known localities for Leprodactylus silvanimbus in Departamento de Ocotepeque, Honduras. We found a new breeding site for the species, recorded its advertisement call, and collected and observed its adults and larvae. The purpose of this paper is to present the results of these new findings and to comment on the relationships L. silvanimbus.

Características De La Osificación Craneal En Phyllomedusa Boliviana (Anura: Hylidae), Rafael O. De Sá, E. O. Lavilla

Biology Faculty Publications

RESUMEN. Dentro de la familia Hylidae disponemos de información sobre las secuencias de osificación craneal para menos del 4.0% de sus miembros. El presente trabajo describe la secuencia de osificación craneal de Phyllomedusa boliviana. El patrón general de osificación es similar a lo reportado para otras especies de la familia, pero existen algunas diferencias importantes tales como la osificación tardía de los próoticos y la osificación premetamórfica de neopalatino, vómer, cuadrado-yugal, pterigoides y columela. El lento desarrollo ulterior de la osificación resulta en juveniles con cráneos extensamente cartilaginosos.

Parental Investment In The Red-Eared Slider Turtle, Trachemys Scripta, Michael D. Marlen

Masters Theses

This study was conducted to determine egg and hatchling components of the red-eared slider (Trachemys scripta). In addition, energy components transferred from egg to hatchling were used to determine the level of parental investment in embryogenesis and hatchling care. Eggs of the red-eared slider, collected from central Illinois ponds, were obtained by inducing gravid females to lay by an injection of oxytocin. Egg and hatchling lipids were extracted with petroleum ether while egg and hatchling protein content was determined using the micro-Kjeldahl procedure. Eggs averaged 70.7% water by mass, and dry mass of whole eggs and egg yolks averaged 2.4g …

Reproductive Responses Of Iphiseius Degenerans And Neoseiulus Teke (Acari: Phytoseiidae) To Changes In The Density Of The Cassava Green Mite, Mononychellus Tanajoa (Acari: Tetranychidae), F. E. Nwilene, G. Nachman

All Peer-Reviewed Publications

We assessed the reproductive responses of adult female Iphiseius degenerans and Neoseiulus teke to increasing density of three stages of their prey, Mononychellus tanajoa, on cassava leaf discs under laboratory conditions. The oviposition rates increased with number of prey consumed per predator per day with a maximum of approximately two eggs per day for I. degenerans and four eggs per day for N. teke. The oviposition rate of N. teke was higher when consuming eggs than other prey stages. Neoseiulus teke was more efficient than I. degenerans in converting consumed prey into egg production. The data were adequately described by …

Fall Field Report, August-November 1995, W. Ross Silcock

Nebraska Bird Review

Generally this was a "normal" fall, if there is such a thing; a few new early and late dates but no pattern, a few notable species showing or absent, and a few rarities. Grebes and loons were in evidence, including Red-throated and Pacific Loons and Red-necked Grebe, but geese did not arrive (or were not reported) in great numbers by the end of the period. The less common herons were in good numbers, notably Snowy Egret, and also Little Blue Heron and Yellow-crowned Night-Heron. Notable for their absence were the thrushes; few Swainson's were found, and no Gray-cheeked, Veery, or …
