Progress And Prospect Of A Bioenergetic Simulation Model Of Pine Vole Populations, John F. Coyle, Kevin C. Jordan, Alan R. Tipton, Roy L. Kirkpatrick

Eastern Pine and Meadow Vole Symposia

As reported previously (Coyle and Tipton 1980), we have been engaged in the development of a computerized system which outlines the basic demographic features of a pine vole population. The system, when complete, will hopefully contain four subsystems (biological, spatial, control and economic). This paper will discuss the biological submodel, its development and validity, and prospects for its future.

Meadow And Pine Vole Control I N 1980 Field Plots, Ross E. Byers, Mark H. Merson

Eastern Pine and Meadow Vole Symposia

Broadcast treatments of Volak (Brodifacoum), Rozol (Chlorophacinone), ZP Rodent Bait AG, and Ramik-Brown (Diphacinone) gave excellent to good control of voles in decreasing order of effectiveness. A saccharin formulation of Ramik-Brown or doubling the concentration of diphacinone to 0.01% did not result in any additional control over the current formulation. Hand placement of ZP Rodent Bait AG at 1 to 3 lbs/A gave excellent control of voles. Place packs of ZP Rodent Bait AG were not opened at all sites, however, residual activity from apple activity data indicated that this product gave excellent control. Additional field and laboratory evaluations were …

Review Of The Island Waterfowl By Milton W. Weller, And The Hawaiian Goose: An Experiment In Conservation By Janet Kear And A. J. Berger, Paul A. Johnsgard

Paul Johnsgard Collection

Both of these books deal with insular species of waterfowl. The volume by Weller concentrates on the ecological forces that have shaped the compar- ative ecologies and morphologies of some 30 forms of Anatidae that are confined to the islands of the world; the Kear and Berger book deals with the interesting history of the ill-fated Hawaiian goose, or nene, which has at least temporarily been saved from extinction by heroic conservation measures of the Wildfowl Trust and Hawaiian wildlife personnel.

WHITE-WINGED SCOTER. On 1 May 1980 I had a White-winged Scoter in the yard, at most times not more than 15 to 20 feet away from me. It was here an hour or so before the neighbor's cat caused it to fly. I take it that it was very tired or sick because it would just keep moving enough that I couldn't get any closer.

1980 Christmas Count

Nebraska Bird Review

One hundred and two species (three more than last year) were reported in the 1980 Christmas Count, and three species (two more than last year) were reported present during the count week but not seen on the count day. These increases were in spite of one less count Crawford - this year. Two additional races were reported, compared to three last year. The individual count this year was 317,910, compared to 188,102 last year, with the Snow Goose count at Omaha, particularly, and at DeSoto and the Mallard count at DeSoto accounting for more than the difference between the two …

Social Behavior And Activity Patterns Of Meadow Voles In Relation To Seasonal Change And Snow Cover, Ronald J. Brooks, A. Bruce Webster

Eastern Pine and Meadow Vole Symposia

Activity and social behavior of free-ranging meadow voles (Microtus pennsylvanicus) were examined in summer, fall, and winter using capture-recapture and radiotelemetry. The composition of our study population changed from predominantly reproductively-active (RA) voles in summer and fall to entirely non-reproductively-active (NR) voles in winter. RA males had larger activity areas than RA females. Activity areas of RA females did not overlap with those of other RA females, but activity areas of RA males overlapped extensively with those of both RA males and RA females. However, any contact among RA voles was rare, unless females were estrous. NR voles …

A New Species Of Rhynchomys (Muridae) From The Philippines, Guy G. Musser, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

". . . Mr. Whitehead has made a most wonderful and unexpected discovery, that of a new and peculiar Mammal-fauna inhabiting the Luzon highlands, and, so far as is yet known, mostly isolated on a small plateau on the top of Monte Data, in the centre of Northern Luzon, at an altitude of from 7000 to 8000 feet." With this dramatic announcement, Oldfield Thomas (1898:377) introduced to naturalists the spectacular rats found by Whitehead: Crateromys schadenbergi, Carpomys melanurus, C. phaeurus, Batomys granti, Chrotomys whiteheadi, Celaenomys silaceus, and Rhynchomys soricoides. One of the most interesting of these to Thomas was …

Correspondence Of Food Habits And Morphology In Insectivorous Bats, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

In a morphometric study of molossid bats (Freeman, in press), I found that the first principal component (PC) reflected overall size. The second PC was concerned with a suite of jaw and skull measurements that separated molossids with thicker jaws, fewer but larger teeth, and welldeveloped cranial crests (i.e., bats with robust skulls) from those with thinner jaws, more but smaller teeth, and less developed cranial crests. Subsequently, I found (Freeman, 1979) that molossids with robust skulls ate hard-shelled insects such as beetles. and that molossids with gracile skulls ate soft-bodied insects such as moths. Given these conclusions I was …

Trematode-Gastropod Associations In Nine Non-Lacustrine Habitats In The Mwanza Region Of Tanzania, Sam Loker, H. G. Moyo, Scott Lyell Gardner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Between August 1978 and July 1979, freshwater gastropods were collected at monthly intervals from 9 different non-lacustrine habitats in the Mwanza region of Tanzania. Of a total of 11 708 gastropods representing 14 species, 1748 (14.9 %) were infected with trematode sporocysts and/or rediae. Altogether 38 morphologically distinguishable ‘species’ of cercariae were recovered (13 furcocercous, 10 xiphidiocercaria, 6 echinostome, 4 cystophorous, 3 gymnocephalous and 2 amphistome species), 22 of which did not conform to previously described African species. The majority (63.8%) of all mature infections were xiphidiocercariae. Biomphalaria pfeifferi, B. sudanica and Ceratophallus natalensis each yielded 11 species of …

Function Of Mentzelia Nuda (Loasaceae) Postfloral Nectaries In Seed Defense, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Mentzelia nuda is a coarse, short-lived perennial of the High Plains of North America. The flowers secrete nectar which serves as an attractant for pollinating bees. Postfloral nectar secretion attracts ants whose presence significantly enhances seed set. This is the first demonstration of advantage to postflowering activity of a floral nectary.

Relationship Between Production And Stayability In Holstein Cattle, G. F. S. Hudson, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Records from 97,555 first daughters of 1,487 Holstein sires in artificial insemination were used to estimate components of variance and covariance of first lactation milk and fat production and stayability to 36, 48, 60, 72, and 84 mo of age. Henderson's Method 3 was used with a model including fixed herd-year- season and genetic group effects and random sire within group and residual effects. Heritabilities for milk and fat production and 36-, 48-, 60-, 72-, and 84-mo stayability were .31, .30, .02, .04, .05, .05, and .05. Genetic and phenotypic correlations between milk production and stayability ranged from .47 to …

François Lamy And The Rhetoric Of Attention Of Malebranche, Thomas M. Carr Jr.

French Language and Literature Papers

François Lamy is always mentioned in the lively polemic over rhetoric touched off in 1694 by the attack of Goibaud Dubois against pulpit eloquence. The Benedictine Lamy became the center of the controversy when a 1698 éclaircissement of his De la connaissance de soi-même (5 vols. Paris, 1694-1698) provided the most thorough critique of the ancient art the quarrel produced. Malebranche himself did not participate directly in this dispute, but since he had made similar criticisms in passing in the Recherche de la vérité (1674) his presence was constantly felt in the background. This resemblance is no coincidence. According to …

Observations On Bats From Trinidad, With A Checklist Of Species Occurring On The Island, Catherine H. Carter, Hugh H. Genoways, Robert S. Loregnard, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

In their comprehensive treatment of the bats of Trinidad, Goodwin and Greenhall (1961) reported 58 species from the island. Subsequent authors (Goodwin and Greenhall, 1962, 1964; Genoways et al., 1973a; LaVal, 1973a, 1973b) have added some species to the list and changed the status of others so that the known chiropteran fauna of Trinidad now comprises 64 species: five emballonurids, one noctilionid, four mormoopids, 36 phyllostomids (see Handley, 1980, for family-group names), one natalid, one furipterid, one thyropterid, seven vespertilionids, and eight molossids. Among the phyllostomids, the subfamilies Phyllostominae (15) and Stenodermatinae (14) are the best represented, whereas only a …

Forestry For Wildlife Habitat Improvement. Nebraska Cooperative Extension Service Ec 81-1747, Ec 80-1747, Frank A. Hershey, Howard L. Wiegers

School of Natural Resources: Faculty Publications

Wildlife cannot exist without food and protective cover. Natural and planted woodlands contribute significantly to these essentials. This circular describes habitat needs of wildlife, recommends forestry practices for habitat improvement, and gives examples of practices to improve habitat for pheasant, quail, and deer.

Variety, rather than uniformity of vegetation, benefits most wildlife species. Management which results in a diverse plant community with many stages of growth can increase the numbers and species of wildlife. Techniques which create improved conditions for woodland wildlife are fundamentally the same as those designed to grow good timber.

Through The Trap Door Darkly: Nebraska Exemption Policy And The Bankruptcy Reform Act Of 1978, Richard F. Duncan

Nebraska College of Law: Faculty Publications

The Bankruptcy Reform Act establishes a somewhat disingenuous exemption policy that first creates, and then allows the individual states to nullify, uniform federal bankruptcy exemptions. The State of Nebraska has chosen to opt out of the federal exemption scheme thereupon assuming a continuing moral obligation to ensure that its exemption policy does not deny Nebraska debtors the fresh start following bankruptcy to which they are entitled. The Unicameral should undertake an immediate reconsideration of Nebraska exemption law with a view to possible elimination of the homestead exemption in favor of an expanded exemption in lieu of homestead to be available …

A technique for assigning individuals to age-classes is necessary to understand the population dynamics and behavioral interactions of this species.

The Role Of Nutrient Reserves In Mallard Reproduction, Gary Krapu

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Mallard (Arias platyrhynchos) populations breeding in temperate North America obtain a significant part of the energy and lipid requirements of reproduction at sites occupied prior to arrival on the breeding grounds. Protein for egg formation, however, is obtained principally from the diet during the nesting period. Both sexes arrive heavy and fat in North Dakota but experience substantial weight loss and lipid depletion during the nesting cycle. Weight loss is most pronounced among females and averages 25% from prelaying to late incubation. Body weights of both sexes are positively correlated with carcass lipid content. The paired male draws …
