Dna Extraction From Preserved Trout Tissues, D. K. Shiozawa, J. Kudo, R. P. Evans, S. R. Woodward, R. N. Williams May 1992

Dna Extraction From Preserved Trout Tissues, D. K. Shiozawa, J. Kudo, R. P. Evans, S. R. Woodward, R. N. Williams

Great Basin Naturalist

We have adapted techniques developed for the extraction of DNA from formalin-fixed, paraffin-imbedded human tissues for use on preserved fish tissues. DNA was successfully extracted and the d-loop region of mitochondrial DNA was amplified with the polymerase chain reaction (PCR). The sequences of the amplified DNA from preserved and modern samples were identical. These techniques were also applied to fin tissue treated with a variety of preservatives. Extraction of DNA from ethyl alcohol and air-dried fin tissues gave yields equivalent to those from frozen tissues. Extraction of DNA from preserved museum specimens of rare or extinct taxa could significantly increase …


Survey Of Mollusks Of The Platte River: Final Report, Patricia W. Freeman, Keith Perkins Mar 1992

Survey Of Mollusks Of The Platte River: Final Report, Patricia W. Freeman, Keith Perkins

School of Natural Resources: Faculty Publications

A survey of the mollusks of the Platte River was carried out during the summers of 1990 and 1991. With the exception of the Big Bend Reach of the River in Dawson, Buffalo and Hall counties, no unionids (mussels) were found in the main channel of the river. We found 11 species of mussels along the river and 16 species of snails at 49 different sites from east to west across the state. We found the Asiatic clam, a known, non-native, pest species, for the first time in the state placing it several hundred miles west of the present eastern …

1991 Nebraska Christmas Bird Count Mar 1992

1991 Nebraska Christmas Bird Count

Nebraska Bird Review

1991 NEBRASKA CHRISTMAS BIRD COUNT

The 1991 count yielded a total of 109 identified species (Table 2), and seven not identified to species (Table 1). The number of individual birds totaled 109,335 (Tables 1 and 2). In comparison with the previous two years, there was an increase in the number of identified species in 1991, but a decrease in the number of individual birds, which follows the trend of recent years. The number of reporting locations was 10 in 1991 compared to 6 in 1990 and 14 in 1989. The data and conditions on the dates chosen for the counts …


First Record Of The Cave Swallow For Nebraska, Charles R. Brown, Mary Bomberger Brown Mar 1992

First Record Of The Cave Swallow For Nebraska, Charles R. Brown, Mary Bomberger Brown

Nebraska Bird Review

FIRST RECORD OF THE CAVE SWALLOW FOR NEBRASKA

The Cave Swallow (Hirundo fulva) is patchily distributed from central Texas and southeastern New Mexico south to southern Chihuahua, Coahuila, and San Luis Potosi; in central Chiapas, Yucatan, and Quintana Roo; in the Greater Antilles east to Puerto Rico; and in southwestern Ecuador and northwestern Peru (A.O.U. 1983). Vagrants are occasionally recorded in Arizona, Florida, and along the Gulf and East Coasts of the United States north to Nova Scotia. The Cave Swallow has seldom, if ever, been reported in the north-central U.S. The species is unknown for Nebraska (N.O.U.R.C. …

1991 Fall Occurrence Report, Ray Korpi

Nebraska Bird Review

FALL 1991 OCCURRENCE REPORT

During the period from 1 July to 31 December 1991, 292 species plus a probable escape were recorded in the state. This compares with 284 species for the same period in 1990, 291 species in 1989, 282 species in 1988, 296 in 1987, and 293 in 1986. Tables are arranged in a west-to-east fashion, following major river valleys where possible. The whooping crane and Christmas Count reports, found in other parts of this issue, are not included in this report.

Weather in this period was noteworthy. Most reporters noted a significant drop in bird populations after …

Canine Teeth Of Bats (Microchiroptera): Size, Shape And Role In Crack Propagation, Patricia W. Freeman Feb 1992

Canine Teeth Of Bats (Microchiroptera): Size, Shape And Role In Crack Propagation, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

Upper canines in microchiropteran bats show a variety of cross-sectional shapes. A consistent feature of all species studied here is that the tooth is edged and not simply round or oval. Prominent sharp edges are positioned in several directions but particularly antero-medially toward the incisors and posteriorly toward the premolars. These edges appear to direct the cracks made in food items to the incisors or to the premolars. A continuous cutting edge is apparent in the occlusal view of the palate running from tip of canine to the ectoloph of the molars. Size and shape analysis indicates that larger bats …


Effects Of Moose Foraging On Browse Availability In New Hampshire Deer Yards, Michael T. Pruss, Peter J. Pekins Jan 1992

Effects Of Moose Foraging On Browse Availability In New Hampshire Deer Yards, Michael T. Pruss, Peter J. Pekins

New Hampshire Agricultural Experiment Station Publications

Food habits of moose (Alces alces) and white-tailed deer (Odocoileus virginianus) overlap in northern New Hampshire during autumn and winter. High moose and deer densities in deer yards, where deer may be confined for extended periods, could result in competition for limited deciduous forage. The purpose of this study was to investigate possible impacts by moose on browse availability in deer yards, and the potential effects on deer. Fifteen deer yards were studied in northern New Hampshire during spring and fall, 1990-91. Unbrowsed and browsed deciduous twigs, and deer and moose pellet groups were counted on 900 permanent plots to …

The Impact Of Red Kangaroos On The Rangelands, Grant Norbury, Dale Norbury Jan 1992

The Impact Of Red Kangaroos On The Rangelands, Grant Norbury, Dale Norbury

Journal of the Department of Agriculture, Western Australia, Series 4

Kangaroos and other native animals should be maintained across their natural range, including areas set aside for pastoral use. But the added grazing pressure on native vegetation from sheep, cattle and feral animals, together with unnaturally high numbers of kangaroos, has seriously degraded much of our rangelands. Cattle and sheep numbers are relatively easy to control. The same cannot be said for kangaroos. Access to widespread man-made watering points has allowed kangaroos to continue breeding when normally a shortage of water would suppress reproduction.

Pastoralists complain that commercial kangaroo shooting is not always effective in preventing damage caused by kangaroos. …


Distributional Survey Of The Bird-Voiced Treefrog, Hyla Avivoca (Anura: Hylidae), In Arkansas, Stanley E. Trauth Jan 1992

Distributional Survey Of The Bird-Voiced Treefrog, Hyla Avivoca (Anura: Hylidae), In Arkansas, Stanley E. Trauth

Journal of the Arkansas Academy of Science

A field study of the bird-voiced treefrog, Hyla avivoca, was conducted in Arkansas during the summer of 1991. A total of 75 separate sites in 23 counties was visited. Males with their distinctive whistle-like calls were listened for at night at each site. Breeding colonies of Hyla avivoca were found in four of the six major river basins; the study established three new county records. Currently, this species has been documented at 14 sites in 10 counties; in very few situations were the treefrogs locally abundant (voucher specimens deposited in the Arkansas State University Museum of Zoology). Habitat perturbation and …
