Revised Checklist Of North American Mammals North Of Mexico, 1979, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways Dec 1979

Revised Checklist Of North American Mammals North Of Mexico, 1979, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Faunal checklists provide useful ready references for many kinds of endeavors, both in the laboratory and in the field, and are particularly helpful to students. Since publication more than four years ago of a "Revised checklist of North American mammals north of Mexico" (Jones et al., 1975), demand for that list has exceeded the supply set aside for general distribution; additionally, systematic studies of mammals published since 1974 necessitate changes in the list. Primarily for these reasons, a newly revised checklist of mammalian species occurring in the Nearctic to the north of Mexico is here presented. As in this and …

Eastern Wheatbelt Farm Economics, Peter Eckersley Nov 1979

Eastern Wheatbelt Farm Economics, Peter Eckersley

Soil conservation survey collection

This booklet outlines the current cost structure and profitability of a farm in the eastern wheatbelt. Rather than being figures for an 'average farm', they reflect the use of practices widely recommended by the Department of Agriculture on a typical property in the area. This does not mean the Department of Agriculture believes every farm in the area should be run this way. The best way to run any particular farm depends on the resources and objectives of that farmer.

Distribution And Natural History Of Amphibians And Reptiles In Western Nebraska With Ecological Notes On The Herpetiles Of Arapaho Prairie, Royce E. Ballinger, John D. Lynch, Patrick H. Cole Sep 1979

Distribution And Natural History Of Amphibians And Reptiles In Western Nebraska With Ecological Notes On The Herpetiles Of Arapaho Prairie, Royce E. Ballinger, John D. Lynch, Patrick H. Cole

Papers in Herpetology

Introduction: The distribution and natural history of amphibians and reptiles have been little studied in the northern states of the great plains. Relative to other vertebrate groups, the herpetofauna of grasslands is depauperate particularly at higher latitudes where temperature becomes a limiting factor to poikilotherms. Nevertheless, certain species of amphibians and reptiles are common in specific habitats and thus form a conspicuous component of the prairie fauna. The purposes of the present study were to document the distributions of herpetiles in a specified region of western Nebraska and to describe general aspects of their natural history. We hope such information …


Morphology And Distribution Of Petiolar Nectaries In Ipomoea (Convolvulaceae), Kathleen H. Keeler, Robert B. Kaul Sep 1979

Morphology And Distribution Of Petiolar Nectaries In Ipomoea (Convolvulaceae), Kathleen H. Keeler, Robert B. Kaul

School of Biological Sciences: Faculty Publications

The distribution of petiolar nectaries in 24 species of Ipomoea was investigated. Petiolar nectaries were found on 12 species (8 new reports, 4 confirmations of previous reports) and quoted from the literature as being found on 3 other species; they were absent from 9 species investigated. The structure of petiolar nectaries in the genus ranges from simple beds of superficial nectar-secreting trichomes (1 species), to slightly recessed "basin nectaries" (8 species), to "crypt nectaries," which are structurally the most complex extrafloral nectaries known (3 species). (Structures were not determined for 3 species.) Petiolar nectaries are present in all subgenera, but …

Distribution Of Plants With Extrafloral Nectaries And Ants At Two Elevations In Jamaica, Kathleen H. Keeler Jun 1979

Distribution Of Plants With Extrafloral Nectaries And Ants At Two Elevations In Jamaica, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Frequencies of plants with extrafloral nectaries were determined for two elevations in Jamaica. Extrafloral nectaries were found on 0.28 of the plants at sea level (Happy Grove, Portland) and 0.00 of the plants at 1310 m (Whitfield Hall, St. Thomas). Ant abundance, as indicated by discovery of and recruitment to baits, was greater at the lower elevation site. However, despite the apparent absence of plants with extrafloral nectaries, there were abundant ants at 1310 m.


A Study Of Nongeographic Variation In Tatera Leucogaster (Mammalia: Rodentia) From Botswana, Pierre Swanepoel, Duane A. Schlitter, Hugh H. Genoways Mar 1979

A Study Of Nongeographic Variation In Tatera Leucogaster (Mammalia: Rodentia) From Botswana, Pierre Swanepoel, Duane A. Schlitter, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Specimens of Tatera leucogaster from six localities in Botswana were tested for variation with age, secondary sexual variation, and individual variation. Of the six age classes recognized, categories I, II, and III each formed their own group, whereas cat egories IV, V, and VI were not separable on a morphometric basis and were considered to be adults. Significant secondary sexual variation was found only in depth of braincase in which females were larger. The only character exhibiting unusually high individual variation was length of posterior palatal foramen. All other characters exhibited individual variation within acceptable limits.

Species With Extrafloral Nectaries In A Temperate Flora (Nebraska), Kathleen H. Keeler Mar 1979

Species With Extrafloral Nectaries In A Temperate Flora (Nebraska), Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Extrafloral nectaries (EFNs) are glands on a plant, not involved in pollination, that produce solutions containing sugars (and other compounds). Long noted by morphologists, EFNs have recently been observed to be part of ant-plant mutualisms. The function of EFNs appears to be to attract aggressive insects, especially ants, which by disturbing or preying upon herbivores, reduce damage to the plant (Janzen, 1966a,b; Elias and Gelband, 1975; Keeler, 1975, 1977; Bentley, 1976, 1977a,b; Schemske, 1978; Tilman, 1978; Inouye and Taylor, 1979; Pickett ad Clark, 1979). Furthermore, they constitute an unusual plant defense against herbivores: at EFNs plants employ ants as a …

Niobrara-Missouri River Fishery Investigations, Larry W. Hesse, Gene Zeurlein, Roger Vancil, Leonard Koziol, Brad Newcomb, Leigh Ann Retelsdorf Jan 1979

Niobrara-Missouri River Fishery Investigations, Larry W. Hesse, Gene Zeurlein, Roger Vancil, Leonard Koziol, Brad Newcomb, Leigh Ann Retelsdorf

Nebraska Game and Parks Commission: Publications

The Niobrara River heads in the table lands of eastern Wyoming and flows 786 kilometers (km) eastward across Nebraska joining the Missouri River near the town of Niobrara, Nebraska. The Niobrara is the largest Missouri River tributary between the last two mainstem impoundments (Lake Francis Case and Lewis and Clark Lake). Fish movement up the Niobrara is prevented by Nebraska Public Power District's (NPPD's) Spencer Hydroelectric Dam, 63.3 km upstream from the river mouth. The lower reach of the river is turbid and carries a considerable load of sand, silt, and organic debris into the Missouri River. The mean annual …


Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech Jan 1979

Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech

USGS Northern Prairie Wildlife Research Center

The wolf (Canis lupus) is a wide-ranging social carnivore with a complex spatial organization (MECH, 1972; 1973). The precise manner in which this organization is maintained is unknown, but territory advertisement using olfactory and acoustic modes seems to be involved.

The acoustic mode includes primarily howling. Within a wolf pack, howling may be useful to reassemble separated members (MECH, 1966; THEBERGE & FALLS, 1967), and may communicate information on individual identity, location, and other behavioral and environmental contingencies (THEBERGE & FALLS, 1967). Between packs, however, howling may serve to advertise territory, communicating the locations of packs and thus …
