"The Eighty-Second Annual Meeting," From Nebraska Bird Review (June 1983) 51(2).
Nebraska Bird Review
The official registration for the eighty-second Annual Meeting, held in Lincoln 20-22 May 1983, was 55. There was the usual slide show and get-together on Friday night, field trips Saturday morning (with demonstrations of bird banding), Saturday afternoon after the meeting, and Sunday morning. The practice of having talks was revived: Mark A. Brogie, Wayne, gave an illustrated talk on "Distribution of Birds of the Niobrara" and James Ducey, Omaha, did the same for "Breeding Status of the Interior Least Tern in Nebraska" before the business meeting. All officers were re-elected: Mrs. Ruth C. Green, Bellevue, President; Gary Lingle, Grand …

Spring And Summer Birds Of The Niobrara Valley Preserve Area, Nebraska: An Annotated Checklist, Mark A. Brogie, Michael J. Mossman
Nebraska Bird Review
The Niobrara Valley Preserve occupies an area of approximately 22,000 ha in north-central Nebraska and includes parts of Brown, Cherry, and Keya Paha counties. This area was purchased in 1980 by the Nature Conservancy because of the unique co-occurrence of habitat types such as ponderosa pine (Pinus ponderosa) forest, eastern deciduous forest, northern forest (represented by white birch, Betula papyrifera), mixed grass prairie, sandhills prairie, and tallgrass prairie all existing within a proximity of 1.5-3 km.
This confluence of habitat types, in conjunction with the area's central geographic setting, creates a significant zone of sympatry among eastern, …

SANDHILL CRANE TRIP. About 30 or so went out to the blind on the Mormon Island Crane Meadows before dawn on 2 April. But not enough before dawn to allow the last of the party to see the Sandhill Cranes before they took off from their roost in the river. But all could see in the sky the huge flocks that took off from other sections of the river. Some went back to the blind before the Cranes came in to roost that night and got to see them settle in for the night. Many other birds were seen from …

Breeding Status Of Selected Bird Species In The Niobrara Valley Preserve Area, Nebraska, Michael J. Mossman, Mark A. Brogie
Nebraska Bird Review
INTRODUCTION
The Niobrara Valley Preserve is located in north-central Nebraska and includes a variety of relatively undisturbed grassland, woodland, and wetland habitats. The diversity of habitats, in conjunction with the area's central geographic location near the 100th meridian, results in a diverse avifauna with many species and subspecies occurring at or near the western, eastern, southern, or northern edge of their breeding ranges. Several pairs of sibling species and subspecies are found here within their narrow band of sympatry. The breeding list of the Preserve and environs includes at least 105 species (Brogie and Mossman 1983), several of which are …

Notes On The Birds Of The Lower Niobrara Valley In 1902 As Recorded By Myron H. Swenk
Nebraska Bird Review
An expedition consisting of Messrs. J.C. Crawford, Jr., W.D. Pierce, and myself, was sent out by the Department of Entomology and Ornithology of the University of Nebraska during the summer of 1902, into the lower Niobrara valley in order to examine and collect specimens of the fauna of that region After August 1, Professor Bruner also worked with us. Although essentially an entomological expedition, considerable attention was paid by different members of the party to the birds, and some fairly interesting and valuable ornithological notes were secured.
The party started from Long Pine on June 14, and proceeded down the …

Bats: Winged Maestros Of The Night, Patricia W. Freeman
University of Nebraska State Museum: Mammalogy Papers
Most people are both revolted and fascinated by bats. Revolted because, like snakes, bats are assumed to be dangerous, and fascinated because they have bizarre faces and are rarely seen. Bats don't come in contact with humans often because we are active during the day and most bats are active only at night. Also, bats fly and would not be that easy to observe even if they did come out in the day.There are nearly four thousand species of mammals on earth, and nearly one thousand of these are bats. Next to rodents, bats are the most abundant mammals.

An Evaluation Of Small Rodents In Four Dismal Swamp Plant Communities, F. Elizabeth Breidling, Frank P. Day Jr., Robert K. Rose
Biological Sciences Faculty Publications
Diversity and density of small rodents in the Dismal Swamp are believed to be low. Reasons for this may be excessive predation, heavy interspecific pressure from large rodents, lack of suitable habitat, low food availability or flooding.
Rodent populations were evaluated using live-traps and pitfall traps in four different Dismal Swamp plant communities. Habitat was compared on the basis of phytomass studies previously reported. Flood levels were recorded during live-trapping sessions. Mast from trees was collected in modified mast collectors, and fed to Peromyscus leucopus in the laboratory.
Only two small rodent species were captured: Ochrotomys nuttalli and Peromyscus leucopus …

CATTLE VS. WATERFOWL. After three years of comparatively dry weather that kept our rainwater basins dry most of the time, in 1982 we had lots of rain and lots of water in our basins. The rains started the latter part of April and the waterfowl and shorebirds came in great numbers. Although the water levels raised with each rain, the vegetation grew fast enough to keep most of the water covered. This is where the nesting population of Coots, Pied-billed Grebes, etc., hide their nests, and it is hard to guess how many birds are nesting or where the nests …

A Winter Roadside Survey Of Hawks In Eastern Nemaha County, Nebraska, Steve Shupe, Robert Collins
Nebraska Bird Review
During the winters of 1980-81 and 1981-82 roadside surveys of hawks were conducted on 76 square miles (196.8 square kilometers) of Nemaha County, Nebraska. Forty surveys were conducted each winter to acquire baseline data on distribution and populations. Ten species were observed, with the Red-tailed Hawk (49.7%) and the American Kestrel (21.5%) comprising more than 70%of all sightings. Population estimates for each species were determined by using square mile extrapolation and the bounded count method. Intervals of confidence were calculated in an attempt to determine upper and lower winter population limits.

Quantification Of Competition Among Coexisting Heteromyids In The Southwest, Cliff A. Lemen, Patricia W. Freeman
University of Nebraska State Museum: Mammalogy Papers
Three trapping grids, 225 m on a side were established in the desert of southern New Mexico. On grid 1 all Dipodomys (Heteromyidae, Rodentia) were removed; on grid 2 all Perognathus (Heteromyidae, Rodentia) were removed; and on grid 3 no rodents were removed. All grids were censused at two-week intervals for six weeks. When the larger Dipodomys (40g) were removed, the Perognathus (15g) population increased 2.56-fold (from 27 to 69 individuals) in two weeks. Removal of Perognathus had no effect on numbers of Dipodomys. Our data allow us to estimate the magnitude of the competition between Dipodomys and Perognathus …

Life History Of The Lahontan Cutthroat Trout, Salmo Clarki Henshawi, In Pyramid Lake, Nevada, William F. Sigler, William T. Helm, Paul A. Kucera, Steven Vigg, Gar W. Workman
Great Basin Naturalist
The Pyramid Lake Lahontan cutthroat trout (Salmo clarki henshawi) population was sampled on a monthly basis from November 1975 through December 1977. A subsample of 676 trout, stratified by fish size and lake habitat, provided biological data. The entire population is presently derived from hatchery production, stocked at lengths of approximately 75 to 300 mm. Peak annulus formation occurs in March and April, followed by the period of maximum growth. Scale patterns illustrate a variable growing season. Maximum growth in length is in the first three years of life; after that males begin to grow faster than females. …

The Distribution, Ecology And Growth Of The Chestnut Lamprey, Ichthyomyzon Castaneus, In The Clearwater River, Minnesota, Charles S. Holt, Paul A. Durkee
Journal of the Minnesota Academy of Science
This study dealt primarily with the ammocoete stage of the chestnut lamprey, lchthyamyzan castaneus (Girard). The population estimate for ammocoetes in the 25.5 m2 section studied was 540 individuals. The lengths of 452 ammocoetes collected ranged from 42 to 164 mm. A total of 213 chestnut lampreys were retained for laboratory study. Twenty of these were adults with an average length of 136.8 mm (range= 125 mm to 191 mm). Six age classes of ammocoetes were determined. An average increase in body length of recaptured ammocoetes of 2.9 mm was observed during the summers of 1980 and 1981. The habitat …

Siberian Tiger Species Survival Plan: A Strategy For Survival, U. S. Seal, T. F. Foose
Journal of the Minnesota Academy of Science
The wild population of Siberian tigers (Panthera tigris altaica) is estimated at about 300 in six separate populations. Since an effective population size of at least 500 is necessary for long-term survival and evolution, and since the wild populations are not going to be able to expand in their natural habitat, it is evident that a captive breeding program is necessary for sustained preservation of this form. There are 1000 living Siberian tigers in zoos; only three outside of Russia are wild-born. About 250 are in North American zoos. Although about 68 wild-caught animals have been brought into zoos, six …

Dynamic Effects Of Food Magnitude On Interim-Terminal Interaction, Alliston K. Reid, Robert H.I. Dale
Scholarship and Professional Work - LAS
We tested the assumption of a facilitatory relation between periodic food presentation and schedule-induced drinking by examination of (a) elicited drinking, (b) drinking in anticipation of food delivery, and (c) possible indirect effects of food delivery on drinking. We exposed rats to a fixed-time 60-second schedule in which interfood intervals ended in either one or four food pellets with equal probability. In Phases 1 and 3, a stimulus signaled the magnitude of upcoming food presentation. In Phase 2, the stimulus was eliminated. Changes in drinking and "head-in-feeder" distributions within interfood intervals demonstrated that head-in-feeder was controlled directly by food presentation, …
Mensural Discrimination Of The Skulls Of Arkansas Peromyscus, V. Rick Mcdaniel, C. Renn Tumlison, Phil Mclarty
Mensural Discrimination Of The Skulls Of Arkansas Peromyscus, V. Rick Mcdaniel, C. Renn Tumlison, Phil Mclarty
Journal of the Arkansas Academy of Science
Twelve parameters were measured on skulls of four species of Peromyscus from Arkansas. Univariate statistical tests, multivariate analyses of variance, and principal axis factor analyses were performed on the data set and/or subsets in a search for species-level discriminating characters. Total length of skull was found to discriminate between skulls of P. maniculatis, P. leucopus, and a combined group of P. attwateri and P. gossypinus. Furthermore, the ratio of interorbital width and length of nasal bone was found to adequately discriminate between skulls of P. attwateri and P. gossypinus.

The Effect Of Repeated Spermiation On Sperm Density In The American Toad (Bufo Americanus), Michael A. Kriz
Masters Theses
Bufo americanus (American toad) responds to LH-RF injections by releasing sperm into the cloaca. An ANOVA test (repeated measures) was used to determine that spermiation number and body size but not frequency of injection affected sperm density. The affects of body size on sperm density were that large toads produced the highest sperm densities, followed by the medium and then the small toads. Sperm density decreased with repeated spermiations which could correlate with the explosive breeding pattern of the American toad.
