Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf
Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf
Avian Cognition Papers
An ecological approach based on food distribution suggests that hummingbirds should more easily learn to visit a flower in a new location than to learn to return to a flower in a position just visited, for a food reward. Experimental results support this hypothesis as well as the general view that differences in learning within and among species represent adaptations.
Teton Wildlife: Observations By A Naturalist, Paul A. Johnsgard
Teton Wildlife: Observations By A Naturalist, Paul A. Johnsgard
Papers in Ornithology
The diversity of wildlife in Grand Teton National Park and its environs draws millions to the valley of Jackson Hole every year, but few are the visitors who are able to observe individual species over the course of several seasons. Paul Johnsgard, a noted naturalist who has written many books on the waterfowl of the world, here integrates his own observations with those who have studied Teton wildlife in the past. The result is a compassionate, simple reconstruction of the lives of a few individuals from spring through early autumn.
Teton Wildlife describes the migration of a herd of antelope …

The Red-Tailed Hawk On Sauvie Island, Oregon, Kevin J. Lien
The Red-Tailed Hawk On Sauvie Island, Oregon, Kevin J. Lien
Dissertations and Theses
A study was undertaken to determine the abundance, distribution, perching heights, diets and territory sizes of Red-Tailed Hawks on Sauvie Island, Oregon. Sauvie Island supported a large wintering population of non-territorial Red-Tailed Hawks. The establishment of territories began around 10 January. Average perch height was found to be 14.2 m. Average perch height increased from fall to spring, corresponding-to the onset of the breeding season and to the onset of egg-laying and incubation. Voles (Microtus spp.) were the principal prey year-round, though waterfowl were more important in terms of biomass in the winter and early spring. Territory sizes on the …
Temporal And Phenomenological Aspects Of Social Behavior In Captive Wolves (Canis Lupus L.), Paul C. Paquet
Temporal And Phenomenological Aspects Of Social Behavior In Captive Wolves (Canis Lupus L.), Paul C. Paquet
Dissertations and Theses
Although cooperative behavior is generally acknowledged to occur among wolves, there is a lack of systematically collected data confirming the extent of development. The objectives of this study were to collect long-term, detailed observations documenting the role of social structure, seasonal influences, and individual participation in wolf pack cooperative activities. Individual cooperative strategies were associated with age, sex, and social positions and critically compared with results of similar studies. Emphasis was placed on quantifying group and dyadic relationships, focusing on reproductive strategies and dominance structure. Additional data were collected on denning behavior, maternal care behavior, scent marking, and spontaneous individual …
Systematic Review Of The Texas Pocket Gopher, Geomys Personatus (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways
Systematic Review Of The Texas Pocket Gopher, Geomys Personatus (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
The Texas pocket gopher (Geomys personarus), which occupies a range in southern Texas and extreme northeastern Tamaulipas, was examined for morphological variation. Univariate and multivariate analyses were used to determine age, secondary sexual, individual, and geographic variation. Significant differences were found among the three age classes and between the sexes for 12 of 13 cranial measurements. Males displayed higher individual variation than females. Distributions of the six previously recognized subspecies (fallax, fuscus, maritimus, megapotamus, personatus, and streckeri) were examined. An additional subspecies is recognized and described. Of the seven subspecies of …
Intraisland And Interisland Variation In Antillean Populations Of Molossus Molossus (Mammalia: Molossidae), Hugh H. Genoways, Robert C. Dowler, Catherine H. Carter
Intraisland And Interisland Variation In Antillean Populations Of Molossus Molossus (Mammalia: Molossidae), Hugh H. Genoways, Robert C. Dowler, Catherine H. Carter
University of Nebraska State Museum: Mammalogy Papers
Significant levels of secondary sexual variation and expected levels of individual variation were demonstrated in all samples of Molossus molossus from Jamaica, Guadeloupe, and Trinidad examined with univariate analyses. Significant morphometric differences were demonstrated among samples of Molossus molossus that originated from geographically close localities on the same island. Using multivariate techniques, broader patterns of geographic variation were demonstrated among the Antillean populations of M. molossus.

Distribution And Taxonomic Status Of Blarina Hylophaga Elliot (Insectivora: Soricidae), Sarah B. George, Jerry R. Choate, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Systematic relationships of southern populations of short-tailed shrews (genus Blarina) are assessed on the basis of univariate and multivariate statistics. Populations are separated into two phena; southwestern short-tailed shrews are significantly larger morphometrically than southeastern forms. The two phena apparently represent distinct species. The name Blarina hylophaga is available for southwestern populations, and the name Blarina carolinensis is here restricted to short-tailed shrews in the southeastern United States.

Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson
Marine Affairs Theses and Major Papers
Until the establishment of the Fishery Conservation and Management Act of 1976 (FCMA), fish outside the United States' twelve mile fishery zone were, according to international law, common property and belonged to the nation or individual that caught them. This common property law was based on the concept that fish resources were so large that no amount of fishing would interfere with the right of others to catch fish. Modern technology, however, has created equipment that enabled foreign and domestic fishermen to over-fish the resource. A reduced domestic catch led coastal fishermen to support a bill that unilaterally extended the …

The Systematics And Biology Of The Genus Zapus (Mammalia, Rodentia, Zapodidae), Gwilym S. Jones
All-Inclusive List of Electronic Theses and Dissertations
This study was undertaken to determine specific and intraspecific relationships within the genus Zapus (Mammalia, Rodentia, Zapodidae). Subspecies are based on the biological subspecies concept where the subspecies is an evolutionary step between a population and species. Approximately 20,000 Recent specimens and representatives of fossil taxa were examined. Cranial and postcranial characteristics, colors, and when available bacula, sperms and karyotypes were incorporated into the morphological analyses. In addition, published biological data were summarized and analyzed for evidence of primary and secondary isolating mechanisms. Supplemental data were acquired during collection of 450 specimens in midwestern and western United States, western Canada, …
Small Mammals In Openings In Virginia's Dismal Swamp, Robert K. Rose
Small Mammals In Openings In Virginia's Dismal Swamp, Robert K. Rose
Biological Sciences Faculty Publications
In a study of small mammals of openings in the Dismal Swamp of Virginia, seven species were obtained using pitfall traps. Samples included several species rarely caught in the Swamp - seven specimens of the Dismal Swamp subspecies of the southern bog lemming, Synaptomys cooperi helaletes, the first collected in this century; two least shrews, Cryptotis parva; and 15 southeastern shrews, Sorex longirostris fisheri . Results are compared to previous studies, conducted primarily in forested habitats, in which the white-footed mouse, Peromyscus leucopus, and the golden mouse, Ochrotomys nuttalli, were numerically dominant.
Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways
Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Electrophoretic and albumin immunological data indicate that the Brachyphyllinae as currently conceived is a natural assemblage, with Erophylla sezekorni and Phyllonycteris aphylla being more closely related to each other than either is to Brachyphylla cavernarum. In both data sets, values that distinguish Erophylla from Phyllonycteris are in the general range of values that characterize congeneric species of mammals. Immunological distance values for the species Glossophaga soricina, Monophyllus redmani, Anoura caudifer, Leptonycteris sanborni, Choeroniscus minor, and Hylonycteris underuoodi indicate that these taxa are approximately equidistant from the Brachyphyllinae. Immunological comparisons of Glossophaga and Monophyllus to Anoura, Leptonycteris, Choeroniscus, …

Mice Of The Genus Peromyscus In Guadalupe Mountains National Park, Texas, John E. Cornely, David J. Schmidly, Hugh H. Genoways, Robert J. Baker
University of Nebraska State Museum: Mammalogy Papers
Mice of the genus Peromyscus are found in virtually every habitat type in Guadalupe Mountains National Park in West Texas. Because of their abundance and wide distribution, they comprise an important component of the park's ecosystem. The first known specimens of Peromyscus from the area now included in the park were collected by Vernon Bailey in 1901 (Bailey, 1905). He collected specimens of Peromyscus boyIii in Dog and McKittrick canyons. Davis (1940) collected P. leucopus at Frijole in 1938 and P. boylii in The Bowl in 1938 and 1939. Davis and Robertson (1944) reported collecting P. pectoralis from along Bell …
Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech
Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The gray wolf Canis lupus occupies only about 1 percent of its former range in the lower 48 states (Mech 1974a). Most of the range is in northern Minnesota, where the resident population is classified as "threatened" by the U.S. Department of the Interior. Wolves have been and will continue to be the subject of considerable controversy in Minnesota.
The first scientific study of wolves in Minnesota was conducted by Olson (1938a,b). That and all subsequent re- search was in the Superior National Forest (SNF) of northeastern Minnesota even though wolves inhabit approximately the northern third of the state. Consequently, …
A Quantitative Description Of Migratory Behavior Of The Brown Shrimp (Penaeus Aztecus) With Applications In Fisheries Management, Anne Madolyn Babcock
A Quantitative Description Of Migratory Behavior Of The Brown Shrimp (Penaeus Aztecus) With Applications In Fisheries Management, Anne Madolyn Babcock
OES Theses and Dissertations
A quantitative description of the migratory behavior of the brown shrimp, Penaeus aztecus, was established using the density approach. A theoretical time density was estimated by the proportion of catch and catch per boat hour NOAA-NMFS fisheries statistics collected in Pamlico Sound, the Neuse River, and Core Sound. A clear quantitative description of brown shrimp migratory timing is found in the time densities. The impact of various physical tactors on the progress of the fishery in time and space can be objectively evaluated by using the time density statistics as dependent variables in modeling efforts. The distributions also enable …

Radial-Maze Performance In The Rat Following Lesions Of Posterior Neocortex, Melvyn A. Goodale, Robert H.I. Dale
Radial-Maze Performance In The Rat Following Lesions Of Posterior Neocortex, Melvyn A. Goodale, Robert H.I. Dale
Scholarship and Professional Work - LAS
The present experiment was designed to investigate the role of posterior neocortex (areas 17, 18 and 18a) in the maintenance of performance on the radial maze. Following training to criterion on the 8-arm radial maze, rats received either sham operations, bilateral eye enucleations, lesions of posterior neocortex, or combined enucleations and lesions of posterior neocortex. While the enucleated animals with intact brains showed a slight, but significant performance decrement relative to the sham-operated group, the other two groups, with lesions of areas 17, 18 and 18a, each showed a massive deficit. This large deficit was observed even in the group …

Remembrance Of Places Lasts: Proactive Inhibition And Patterns Of Choice In Rat Spatial Memory, William A. Roberts, Robert H.I. Dale
Scholarship and Professional Work - LAS
A series of experiments was carried out to evaluate the notion that rats given a sequence of massed daily trials on the radial maze reset working memory at the end of each trial by deleting its contents. Although curves presented by D. S. Olton [Scientific American, 1977, 236, 82-98: In S. H. Hulse, H. Fowler, & W. K. Honig (Eds.), Cognitive processes in animal behavior, 1978, Hillsdale, N.J.: Erlbaum] show that rats return to errorless performance at the beginning of each trial after the first, the fact that accuracy falls less rapidly over choices on Trial 1 …

Enzyme Linked Immunosorbent Assay For Anatid Herpesvirus, Margaret Anne Lewis
Enzyme Linked Immunosorbent Assay For Anatid Herpesvirus, Margaret Anne Lewis
Biological Sciences Theses & Dissertations
Duck plague virus causes a hemorrhagic disease affecting the family Anatidae, resulting in 60-80% mortality in captive flocks. Plaque and neutralization assays for Anatid herpesvirus (AHV) require 5-10 days for completion and are restricted by the seasonal availability of fertile duck eggs. The enzyme linked innnunosorbent assay (ELISA) is rapid and specific and avoids the use of living cells. The Holland strain of AHV was grown on duck embryo fibroblasts and purified by banding on CsCl gradients. The resulting virus was used to raise antisera in prebled New Zealand white male rabbits. Antibody production was confirmed in double diffusion plates …
