The Report Of The Southern Western Australian Shark Working Group., P. Millington

Fisheries Management Papers

The southern Western Australian Shark Working Group was formed to investigate the southern shark fishery and advise the Minister for Fisheries on options for future management. Membership comprised six fishermen from regional professional fishermen's associations and two Fisheries Department officers. The Working Group considered that each shark fisherman obtaining an entitlement should then be restricted in the length of fishing gear he can use and the number of months he can fish. The individual's time and gear entitlement would be approximately that length of gear being used and time spent fishing in a period shortly before the bench mark date. …

Ectoparasitism As A Cost Of Coloniality In Cliff Swallows (Hirundo Pyrrhonota), Charles R. Brown, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

Colonially nesting Cliff Swallows (Passeriformes: Hirundo pyrrhonota) in southwestern
Nebraska, USA, are commonly parasitized by hematophagous swallow bugs (Hemiptera: Cimicidae:
Oeciacus vicarius) and fleas (Siphonaptera: Ceratophyllidae: Ceratophyllus celsus). We examined to
what degree these ectoparasites represent a cost of coloniality for Cliff Swallows. The number of
swallow bugs per nest increased significantly with Cliff Swallow colony size. Body mass of nestling
swallows at 10 d of age declined significantly as the number of bugs per nestling increased. By fumigating
half of the nests in some colonies, killing the bugs, and leaving half of the nests as nonfumigated …

Fisheries Report No 73 - The Western Rock Lobster Fishery 1981 - 1982, R. S. Brown, E. H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panulirus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. Western Australia produced 10,548 tonnes in 1981/82, out of a total Australian catch of rock lobster of 15,764 tonnes. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and Hancock (1981) and which are designed to limit the total fishing effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to …

Development Of Oriented Lakes In The Eastern Rainbasin Region Of South Central Nebraska, James P. Krueger

School of Natural Resources: Dissertations, Theses, and Student Research

The Eastern Rainbasin region is located on a relatively flat-lying, loess-covered plain. The gently sloping land surface is poorly drained and in places local drainage is toward basins which lack external drainage. In the spring, excell precipitation collects in these basins, forming small lakes and marshes. It is these ephemeral lakes that give the region its name.

Native Hay Production Along A Depth-To-Water-Table Gradient In Eastern Sandhills Wet Meadows, Wheeler County, Nebraska, Jean M. Novacek

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Sandhills region of Nebraska, the largest dune field in the Western Hemisphere, occupies 15 north-central counties and extends over 51,800 km (20,000 mi) (Keech and Bentall, 1971; Ahlbrandt and Fryberger, 1980). Far from a desert, the Sandhills region is entirely vegetated by mixed-grass prairie with numerous wet areas and lakes in interdunal valleys. This rich, grass-covered dune sea stretches 427 km (265 mi) across from east to west and 209 km (130 miles) from north to south. The altitudes range from 670 m (2200 ft) above sea level in the eastern part to 1310 m (4300 ft) in the …

Stocking Density, Strain Performance, And Feeding Method Evaluation Of Cage Reared Rainbow Trout (Salmo Gairdneri) In Eastern South Dakota, Dale B. Allen

Electronic Theses and Dissertations

Methods for cage rearing rainbow trout (Salmo gairdneri) were investigated to assist in the development of a landowner aquaculture program for eastern South Dakota. Rainbow trout when stocked as small fingerlings in the spring did not reach a marketable weight (200 g). The fish did attain a size acceptable to some landowners for personal consumption. Maximum stocking density (fish/m3) was not determined. Densities greater than those used would have been needed to determine the optimum stocking rate. The use of a deeper culture cage (3 m) was justified in this area due to the high water temperatures that were common. …

Ring-Necked Pheasant Cover Use In Eastern South Dakota, Karen Peterson Craft

Electronic Theses and Dissertations

Seasonal cover use of radio-tagged hen pheasants was analyzed and vegetative characteristics of nesting habitat identified in east-central South Dakota during 1983 and 1984. Radio telemetry locations were collected during the summer and fall of 1983 and winter of 1983- 1984 for cover use determinations. Chi-squared analysis of cover use revealed positive selection (P≤0.05) for the idle/roadside cover category in summer, wetlands in fall, and the shelterbelt/woodlot category in winter. Agricultural set aside areas in the 1-year 1983 Payment In Kind (PIK) program were avoided by pheasants in summer as were row crop fields in both summer and winter. Cover …

The Effects Of Three Rodenticides On Nontarget Small Mammals And Invertebrates, Michele S. Deisch

Electronic Theses and Dissertations

Mortality of non-target small mammals and invertebrates using 3 rodenticide treatments (pre-baited zinc phosphide, pre-baited strychnine, and strychnine alone) was evaluated in western South Dakota. Rodenticides were applied September 22-24, 1983 on 15 black-tailed prairie dog (Cynomys ludovicianus) towns. Immediate (September 1983) and long-term (September 1983 through August 1984) rodenticide efficacy and impacts on non-target wildlife species were evaluated. None of the 3 rodenticide treatments produced significant ( a < 0.10) immediate impacts on deer mice (Peromyscus maniculatus) relative densities. Increases of deer mice densities occurred in 1984 on sites that had been treated with the 2 strychnine treatments. These long-term increases in deer mice densities were due to habitat change associated with the absence of prairie dogs. Overall, comparisons among the 3 rodenticides for efficacy indicated that zinc phosphide reduced deer mice densities greater than either strychnine treatment. Seven invertebrate taxa were evaluated. Immediate and long-term effects of the 3 rodenticide treatments occurred when significant differences in invertebrate densities were found between control and treated sites. Spider mites (Acarina) and crickets (Orthoptera) were not affected by the 3 rodenticides. Immediate impacts of zinc phosphide occurred on ant (Hymenoptera) densities and long-term impacts were found in August 1984. Strychnine alone immediately reduced wolf spiders (Araneae) 13% in September 1983 and densities increased on treated sites as compared to control sites in June 1984. Densities of darkling beetles (Coleoptera) in September were significantly reduced with zinc phosphide. Ground beetle and dung beetle (Coleoptera) densities were not immediately reduced by the rodenticides in September. Generally, the few long-term changes in invertebrate densities are attributed to biotic and abiotic factors. Changes in vegetation structure due to prairie dog control may have affected invertebrate densities. Comparisons among rodenticides for efficacy indicated that zinc phosphide immediately reduced densities of ants and darkling beetles greater than either strychnine treatment. None of the other rodenticide comparisons showed significant differences in immediate reductions of non-target invertebrates in September 1983.

A Turkey Nesting Study In Gregory County, South Dakota, Tara L. Wertz

Electronic Theses and Dissertations

Nest site vegetation characteristics and selection by wild turkey hens in Gregory County, South Dakota were examined during 1984 and 1985. A total of 23 adult and 12 juvenile hens were monitored during the study. Average adult nesting rate was 42% (31% in 1984 and 54% in 1985). No juveniles nested either year. Nesting success in 1984 and 1985 was 80% and 0%, respectively. Data was collected from 8 woodland and 5 grassland nests. Nest initiation dates ranged from 20 April to 13 June. Nest sites were chosen in locations having overhanging vegetation within 1 m above the nest bowl. …

An Ecological Study Of Mourning Doves In A Cold Desert Ecosystem On The Idaho National Engineering Laboratory, Frank P. Howe

Electronic Theses and Dissertations

Mourning dove (Zenaida macroura) use of and movements around man-made ponds, as well as dove nesting ecology, were studied from 1983 through 1985 on the Idaho National Engineering Laboratory (INEL). Relative dove use was higher (P < 0.01) on some ponds than others, and multiple regression revealed a positive association (R 2 = 0.49) between relative use and the geographic isolation of ponds. Two peaks in diurnal pond use were exhibited by doves on the INEL: the mourning peak began around 0800 and lasted until approximately 1300, and the evening peak began at about 2030 and ended by 2150. Seasonal pond use fluctuated slightly through the summer then dropped rapidly in early September. Average and average maximum movements indicated that the 41 mourning doves trapped and fitted with radio-transmitters at the Test Reactor Area (TRA) and the Naval Research Facility (NRF) did not move off of the INEL on a regular basis. The average distance from mourning dove locations to TRA and NRF was <2.0 km, and the average maximum dove location was <3.5 km from either facility. Average (<2.0 km) and average maximum (<3.5 km) distances were also measured from dove locations to watering sites. Doves captured at both TRA and NRF moved, on average, 1.5 km from their nests; the average maximum distance from a dove's location to its nest was 2.8 and 5.4 km for doves caught at TRA and NRF. The average maximum distance between any 2 locations (for the same individual) at both TRA and NRF was <4.0 km. Mourning doves on the INEL are primarily ground nesters. Nesting success averaged 68% per year, with 1.8 fledglings produced per successful nest. Nesting densities averaged 0.02 nests/ha during the study. Three peaks in hatching occurred on the INEL: 1 during the fourth week of June, another during the third week of July, and a third during the first and second weeks of August. Annual production estimates for the INEL ranged from 11,300 to 17,000 doves, based on a model using 2 and 3 nesting attempts per summer. No differences (P > 0.05) were indicated in the percent coverage of shrubs, grasses, forbs, and bare ground, as measured with the line-intercept method, in the 5-m area surrounding dove nests and paired random sites. However, a difference in the percentage of grass cover and bare ground, as measured with a point-frame, was indicated in the 1-m2 (microhabitat) centered on the nest or random site; nest sites contained …

Pheasant Nesting And Vegetation Development In Dense Nesting Cover Established Under The South Dakota Pheasant Restoration Program, Emmett J. Keyser Iii

Electronic Theses and Dissertations

Pheasant (Phasianus colchicus) nest use of dense nesting cover (DNC) established under the Pheasant Restoration Program was evaluated in Beadle, Codington, Tripp, and Walworth Counties in South Dakota from 1978 to 1981. Nest densities and success in DNC plots were compared to those found in roadsides and privately owned alfalfa (Medicago sativa) fields, pastures, and small grain fields. Vegetation density and cover development were monitored on DNC plots. Nest densities were generally greatest in DNC plots followed by roadsides and alfalfa fields. Pastures and small grain fields contained the lowest nest densities. No relationship was detected between nest success and …

Seal Development And Infiltration As Affected By Rainfall Kinetic Energy, Deah Abed Mahamad

Electronic Theses and Dissertations

The infiltration of water into soil has been studied for more than 50 years. Much of the effort has concentrated on obtaining infiltration rate measurements for different soils and on developing equations which describe the resulting data. A portion of the infiltration literature has dealt with the large affect that the development of a surface seal has had on the resulting infiltration measurement of a soil. This surface seal may be more significant in determining the infiltration characteristics of a soil than any other single or perhaps combination of factors. Surface seal development has been linked to both rainfall energy …

Growth, Survival, And Reproductive Success Of Largemouth Bass Stocked With Selected Forage Fishes In South Dakota Ponds, R. Dean Beck

Electronic Theses and Dissertations

Five fish stocking combinations were evaluated to determine effects of forage availability and geographic location on largemouth bass (Micropterus salmoides) growth, survival, and reproductive success two and three years following stocking. Four forage species stocked with largemouth bass included bluegills (Lepomis macrochirus), black bullheads (Ictalurus melas), golden shiners (Notemigonus crysoleucas), and fathead minnows (Pimephales promelas). A largemouth bass only stocking strategy was also evaluated. Largemouth bass survival two years after stocking in eastern South Dakota ponds averaged 26.5%. Largemouth bass only and largemouth bass-bluegill combinations exhibited the greatest survival rates (31.6% and 28.8%, respectively), while the largemouth bass-black bullhead combination …
