Evaluation Of Structure And Growth Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Farm Ponds, Charles E. Morris

Electronic Theses and Dissertations

A two-year study estimated standing stock, growth, condition, survival rates, and population structure of bluegills (Lepomis macrochirus) and black bullheads (Ictalurus melas) stocked in South Dakota farm ponds with largemouth bass (Micropterus salmoides). Bluegills and black bullheads reproduced during the second growing seasons and by the end of the study three year-classes of fishes were present in most ponds. Mean back-calculated bluegill total lengths at annuli 1-3 were 58, 125, and 153 mm, respectively. Mean back-calculated black bullhead total lengths at annuli 1-3 were 82, 182, and 240 mm, respectively. A significant north vs south difference (P≤0.05) in third-year bullhead …

Success In Rat Control In Kuwait, K.S. Al-Sanei, T.M. Zaghloul, A.M. Salit, M.T. Omar, M.M. Balba

Vertebrate Pest Conference Proceedings: 11th (1984)

The preliminary rat survey prior to the actual attack phase of Rat Control Program in Kuwait revealed an infestation rate with the Norway rat, Rattus norveqicus, in buildings ranging between 32.7% and 70.7%. The comparatively high infestation was observed in 92.5% of Kuwait buildings. Moreover the infestation reached 99% in certain districts of the country. This high infestation was associated with an increase in rat-borne diseases particularly murine typhus, salmonellosis, rat-bite fever and certain parasitic diseases.

A programme for rodent control in Kuwait was initiated through a political decision by the cabinet which gave the full responsibility of rodent …

Current Status Of Research On The Blackbird-Sunflower Problem In North Dakota, Joseph L. Guarino

Vertebrate Pest Conference Proceedings: 11th (1984)

Since 1979, the Denver Wildlife Research Center, U.S. Fish and Wildlife Service, has conducted an accelerated research program on the blackbird-sunflower problem which occurs annually in the Dakotas and Minnesota. The objective is to develop effective, cost beneficial and environmentally safe methods for reducing blackbird damage to ripening sunflower. A multidisciplinary approach involving interrelated studies of problem definition, ecology, and control methods development is being used. Preliminary results are presented from several studies involving: state- and county-wide estimates of damage; frequency distribution and timing of damage; compensatory growth in early damaged sunflower heads; breeding male blackbird censuses; mass-marking migratory red-winged …

Research On Winter Roosting Blackbirds And Starlings In The Southeastern United States, Donald F. Mott

Vertebrate Pest Conference Proceedings: 11th (1984)

Each winter, more than 300 million blackbirds and starlings congregate in hundreds of roosting sites in the southeastern United States. In addition to nuisance problems involving odor and property damage from fecal material, and potential airport hazards, research studies to date suggest that the major problems with these birds and their roosts involve grain losses in feedlots, latent disease transmission to livestock, and public health concerns with histoplasmosis. Control methods development studies have shown the utility of Starlicide and nonchemical control methods in reducing starling feedlot problems. A sprinkler-irrigation delivery system for the surfactant, PA-14, has been developed that enhances …

Changes In The Lower Chesapeake Bay Food-Chain In Presence Of The Sea Nettle Chrysaora-Quinquecirrha (Scyphomedusa), David Feigenbaum, Michael Kelly

OES Faculty Publications

The abundance of 4 levels of the lower Chesapeake Bay food chain (Chlorophyll a, herbivores, ctenophore Mnemiopsis leidyi, and Scyphomedusa Chrysaora quinquecirrha) were moni­tored twice weekly at 4 stations from May 10 through Sep 30, 1982 in the Lafayette and Elizabeth Rivers (Virginia). The herbivore standing stock, largely copepods, declined sharply in late May when M. Jeidyi appeared, but rebounded a month later when C. quinquecirrha medusae reduced the ctenophore population. Despite the additional presence of Aurelia aurita (Scyphomedusa) from Jul onward, herbivore abundance remained at moderate levels until the end of the study period. Phytoplankton abundance fluctuated …

The Influence Of Soil Moisture, Texture, And Temperature On Nest-Site Selection And Burrowing Activity By The Pine Vole, Microtus Plnetorum, Donald H. Rhodes, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

Pine voles (Microtus pinetorum) have long been recognized as a pest species in fruit orchards of the eastern United States (Hamilton 1935). These semifossorial rodents construct tunnel systems beneath apple trees where they eat entire roots or strip roots of bark and cambium. Hamilton (1938) reported numbers of pine voles within apple orchards as high as 200-300 voles per acre which is in sharp contrast to the relative scarcity of pine voles outside orchard situations (Crain and Packard 1966; Goertz 1971), These findings suggest that orchard habitat provides excellent conditions for pine vole growth and reproduction, although the specific components …

Dispersal And Harvest Of Sage Grouse Utilizing The Test Reactor Area Of The Idaho National Engineering Laboratory, Howard W. Browers, Jr.

Electronic Theses and Dissertations

A radio telemetry study of sage grouse (Centrocercus urophasianus) summering at the Test Reactor Area (TRA) on the Idaho National Engineering Laboratory (INEL) in southeastern Idaho was initiated in July 1980. Objectives included determination of habitat use, home range, brood breakup, fall movements, and harvest of sage grouse using the TRA. Supplemental habitat data and fall movement data were collected from sage grouse summering at the Central Facilities Area (CFA) on the INEL in 1982. Seasonal precipitation appeared to influence the period of use of the TRA by sage grouse. Grouse arrived later and left earlier in the wet year …

Classification And Management Of Wetlands In The Western Kentucky Coal Field, William J. Mitsch, Robert W. Bosserman, Paul L. Hill Jr., Jan R. Taylor

KWRRI Research Reports

This is the first research report of a three-year project on wetland identification and management criteria in the western Kentucky coal field. The region is approximately 12,000 square kilometers and, due to its slight relief, contains many wetlands, some contiguous with surface coal mining operations. The overall objectives of the research project are 1) to identify, classify, and map wetlands in the western Kentucky coal field; 2) to evaluate the major biotic and abiotic factors that affect those wetlands; and 3) to develop strategies for the proper management of those wetlands.

The first report of this three-year project has involved …

Raptor-Mimicking Kites For Reducing Bird Damage To Wine Grapes, Roger L. Hothem, Richard W. Dehaven

Vertebrate Pest Conference Proceedings: 10th (1982)

Preliminary tests in California vineyards during 1979 and 1980 indicated that a raptor-mimicking kite suspended from a helium-filled balloon (kite-balloon or KB) could reduce bird damage to ripening wine grapes. Based on the results of both damage assessments and bird censuses, one KB per hectare, deployed for alternate 1-wk periods, reduced losses caused by birds by about 33% in 1979 and by an average of 48% in 1980 when compared with 1-wk control periods. Habituation by the birds to the KB appeared to reduce its effectiveness over time in 1979, but this problem was reduced in 1980 by regularly changing …

Food Habits And Placental Scar Counts Of Bobcats In South Dakota, David Eric Nomsen

Electronic Theses and Dissertations

Bobcat (Lynx rufus) food habits and placental scar counts were investigated in western South Dakota during 1978-79 and 1979-80 trapping and hunting seasons. Food habits were recorded by frequency of occurrence and placental scar counts were used to determine litter size for South Dakota bobcats. Rabbits (Sylvilagus spp. and Lepus spp.), rats and mice (primarily Microtus spp. and Peromyscus spp.), and deer (Odocoileus spp.) were identified in 56, 32, and 7% of bobcat stomachs, respectively. Analysis showed that rabbits, rats and mice, and deer occurred in 58, 36, and 9% of bobcat intestines, respectively. Occurrences in rabbits decreased from 67% …

Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer

Arkansas Water Resources Center Technical Reports

The response of stream biota to changing water quality or other ecosystem perturbations is an important means of assessing water quality. The dynamic nature of streams induces significant sampling and measurement problems. In smaller streams a true algal plankton subcommunity is lacking and the major location for the production of algae is attachment onto stones and other stable surfaces at the substrate-water interface. Several artificial techniques have been developed to analyze the composition of a portion of the epiphytic periphyton (algae attached to stones) but not populations which are qualitatively and quantitatively similar to natural substrates. A newly developed substrate …

Seasonal Temperature Preference Of Adult Mountain Whitefish, Prosopium Williamsoni, Jean M. Ihnat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Temperatures selected seasonally by adult mountain whitefish were measured in the laboratory in a horizontal gradient. Final preferendum estimates, based on acute (3-hour) preference tests conducted with fish acclimated to 5, 10, and 15 C each season, were 17.7 C (pre-spawning), 11.9 C (post-spawning), 9.9 C (winter), and 16.3 C (spring). Seasonal influence on temperature selection was evident on the basis of differences in final preferenda, covariance analysis of responses of laboratory-acclimated fish, and temperature selection by fish held at ambient river temperatures. Post-spawning and winter groups selected lower temperatures than did pre-spawning and spring groups. Pre-spawning fish selected temperatures …

Natural Pastures Of The Macquarie Region Of New South Wales: Their Origin, Composition And Management, David Leslie Michaelk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two experiments were conducted in the semi-arid (400 millimeter annual rainfall) Macquarie region of New South Wales, Australia, at the Trangie Agricultural Research Station (31° 59'S; 147° S7'E), to examine (a) the way botanical parameters can be used to separate grazing and climatic impacts on range vegetation, and (b) how this delineation affects application of range science tenets (site, condition and trend) to different pasture types.

Two range sites were studied: Site 1, a light soil type, was dominated by annual grasses, legumes and forbs, whereas perennial grasses (mainly Chloris acieularis and Chloris truncata) dominated the heavy soils of …

A Comparison Of Reproductive Strategies Among Marine Snakes, Cliff A. Lemen, Harold K. Voris

School of Natural Resources: Faculty Publications

(1) Gravid females representing fourteen species of marine snakes were collected from four localities along the coast of Malaysia in 1975. The average clutch size ranged from 2.9 to 17.8 but most species had between three and seven young. The number of young produced and the size of gravid Lapemis hardwickii differed significantly at two sites in the Straits of Malacca. Eight species showed a significantly positive relationship between the number of oviducal eggs and female weight. The rate of infertility among ten species ranged from 4.5 to 20%.

(2) Sex ratios in the collections varied significantly through time and …

Growth And Development Rates Of Microtus Pinetorum Under Different Photoperiods, T. L. Derting, J. A. Cransford

Eastern Pine and Meadow Vole Symposia

Photo-period and nutrition are important variables affecting reproductive activity and growth in many rodents. Field and laboratory studies indicate that long photo-period (spring-summer) cause Increased growth while short photo-periods (fall-winter) inhibit these processes. In the montane vole (Microtus montanus) recently weaned animals gain weight at a much lower rate under short photo-periods or in total darkness than under long photo-periods (Vaughan et al., 1973; Peterborg, 1978). Adult M. montanus had more offspring and larger mean litter sizes under LD 18:6 than LD 6:18 (Pinter & Negus, 1965). Similarly, long (LD 16:8) or increasing photo-periods stimulated the onset of …

Fisheries Report No 45 - The Short Term Effects Of Brush Harvesting On The Kwongan Vegetation At Eneabba, Western Australia, E. A. Griffin, A. J. M. Hopkins

Fisheries Research Reports

Areas of the kwongan vegetation south of Eneabba are currently being harvested to provide brush for rehabilitation after mining. Because of the botanical importance of the Eneabba kwongan, a study of the effects of the harvesting was initiated. Three areas with different harvest histories were sampled using quadrats paired across cut/uncut boundaries. Floristic and structural differences between quadrats and between areas were assessed. The store of seed in uncut vegetation was measured.

There was a loss of species as a result of harvesting, at least in the short-term. Many species regenerated by resprouting from buds in damaged stems or in …

Initial Growth And Survival Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Ponds, James J. Shelley

Electronic Theses and Dissertations

Initial growth and survival rates were estimated for bluegills (Leponis macrochirus) and black bullheads (Ictalurus melas) stocked simultaneously with largemouth bass (Micropterus salmoides) in ponds throughout South Dakota. Mean first year survival for bluegills and black bullheads stocked in eastern South Dakota ponds was 28.6% and 67.7%, respectively. Differences in first year bluegill growth throughout the state were not detected. Total lengths for bluegills averaged 52.4 mm after one growing season statewide and 137.1 mm after two growing seasons in southeastern South Dakota ponds. Significant (P<.05) geographical differences in first year growth of black bullheads were detected with mean lengths ranging from 67.7 mm in northwest ponds to 115.5 mm in southeast ponds. The average total length for black bullheads after two growing season in southeastern South Dakota ponds was 215.2 mm. The combined effects of pH, turbidity, and bicarbonate alkalinity accounted for 67.5% of the variation in first year bluegill growth. The pond parameters total number of growing days, fish present prior to stocking, and pond surface area when combined accounted for 73.9% of the variation in first year black bullhead growth. Differences in bluegill relative weight values were not detected throughout South Dakota; the average for the state was 105.2. Mean black bullhead condition factors (K) for fish with total lengths between 128 and 191 mm were 1.85 and 1.45 for pre- and post-spawning periods, respectively. Bullheads probably spawned between 29 May and 26 June 1980.
