Trace Metal Pollution In Narragansett Bay: A Case Study Of The Rhode Island Quahog Fishery, Scott W. Horsley
Trace Metal Pollution In Narragansett Bay: A Case Study Of The Rhode Island Quahog Fishery, Scott W. Horsley
Marine Affairs Theses and Major Papers
This paper was written with two objectives in mind: to provide information relevant to the protection of the quahog fishery and the protection of human health. Both are threatened as hundreds of millions of gallons of industrial effluents and sewage treatment plant discharges enter Narragansett Bay daily. The implications of trace metal pollution with respect to the quahog fishery have received little attention to date. The purpose of this paper is to assemble scientific, legal, and socioeconomic information in a fashion which will direct future research and management attempts in an effective manner.

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 …

Report No 47 - 1980 Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro
Fisheries Research Reports
An account is given of the biological principles involved in decisions concerning duck-shooting seasons in the south-west of Western Australia.
The conditions for waterfowl which prevailed during 1980 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.
1980 was the fifth consecutive year of below-average rainfall in all five Meteorological Districts of the south-west. 1976 to 1980 was thus' the south-west's driest five-year period since 1913 at least.
Low rainfall during 1980 resulted in a further decline in the condition of wetlands throughout most of the inland south-west, Few gauged wetlands increased …

The White Perch, Marone Americana (Gmelin) In Nebraska, Gene Zuerlein
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The white perch, Morone americana (Gmelinl, is a member of the Percichthyidae family. It is a euryhaline species that is common along the northern Atlantic coast south to the Carolinas. Marine, estuarine and freshwater ecosystems with salinities ranging from 5 to 18 percent have been known to support white perch (Mansueti 1964). The species is semianadromous, making spawning runs up coastal streams. It commonly becomes completely landlocked in ponds and reservoirs of its native range where it spawns successfully. This species has been known as a game fish to generations of New England fishermen, but when stocked in landlocked waters …

Die Entwicklung der Hydrobiologie in der MVR vollzog sich unter ständiger Orientierung an den volkswirtschaftlichen Interessen des Landes. Deshalb wurde neben grundlegenden Forschungen zu Fauna und Ökologie der Gewässer besonderes Gewicht auf die Akklimutisierung von Nutzfischen gelegt. Die dazu notwendigen Kenntnisse der hydrobiologisch bisher weitgehend unerforschten Seen der Mongolei erbrachten mehrjährige Expeditionen in verschiedenen Gebieten des Landes. Den gemeinsamen Biologischen Chövsgöl-Expeditionen der Universitäten Irkutsk und Ulan-Balor kommt dabei eine besondere Rolle zu. Am See Chövsgöl entstand auch die erste hydrobiologische Station der MVR. Die rasche Entfaltung der Hydrobiologie in den letzten zwanzig Jahren dokumentiert eine Reihe bedeutender wissenschaftlicher Publikationen ebenso …

First paragraph:
Die Landschaften der Mongolei sind arm an Reptilien- und Amphibienarten. Dieser Umstand mag die Frage aufwerfen, ob herpetologische Untersuchungen in Beschränkung auf das Territorium der MVR eine nennenswerte Perspektive haben könnten, nachdem Artenspektrum und Verbteitung der Species annähernd vollständig erkundet sind. Ein Herpetologe wird zweifellos für seine Arbeit auch in diesem Land eine Zukunft sehen, doch muß wohl von vornherein eingestanden werden, daß das Volumen der Probleme dieses Faches hinter denen der übrigen Disziplinen der Vertebratenzoologie und der Entomologie in einem bescheidenerem Rahmen verbleibt. Dies gilt sowohl im rein wissenschaftlichen als erst recht auch im angewandten Bereich ihrer …

An evaluation of the economics of supplemental irrigation when using a surface water supply must be site specific in order to account for variations in soil moisture holding capacity, watershed area supplying the runoff, climatic conditions, and proposed irrigation management procedures.
With the use of farm specific simulation models to determine grain yields, availability of irrigation water, and economic expenditures involved in irrigation, an economic evaluation of supplemental irrigation can be performed, In the model presented in this report, the Duncan SIMAIZ model is used to predict grain yields using long-term daily weather information. SIMAIZ also determines irrigation water demand …

Data from aerial and landowner surveys showed that red fox (Vulpes vulpes) families on the Sinai study area decreased from 13 (5.2 per township) in 1976 to 11 (4.4 per township) in 1977. The majority (88%) of the active red fox dens was located in pastures and idle lands although these cover types constituted only 24% of the available cover. Twenty-nine juveniles and 3 adults were captured and marked during spring, 1976. Trappers and hunters returned 62% of the tags placed on juvenile foxes. During spring, 1977, 15 juveniles and 2 adult red foxes were marked. Three juveniles were subsequently …

Woodpecker Nesting Habitat In A Prairie River Woodland, J. Barry Parrish
Electronic Theses and Dissertations
Differences in nest site selection of the common flicker (Colaptes auratus), yellow-bellied sapsucker (Sphyrapicus varius), downy woodpecker (Picoides pubescens), and red-headed woodpecker (Melanerpes erythrocephalus) were studied on the Big Sioux River riparian forest of eastern South Dakota during 1980 and 1981. Nest site preferences were compared using two-group stepwise discriminant analysis. Randomly selected potential nest trees showing no previous signs of cavity excavation were included as control groups. The yellow-bellied sapsucker-red-headed woodpecker function was the most efficient in separating groups because both species had specific nest site preferences. Sapsuckers nested only in live green ash (Fraxinus pennsylvanica), characteristically in park-like …

Growth And Survival Of Largemouth Bass In Newly Stocked South Dakota Impoundments, Clifton C. Stone
Electronic Theses and Dissertations
The present study was designed to evaluate the effect of five different stocking combinations and differences in climatic and morphological conditions within South Dakota on initial growth and survival of the largemouth bass (Micropertus salmoides). Forage species stocked with bass included gold shiners (Notemigonus crysoleucas), fathead minnow (Pimephales promelas), black bullhead (Ictalurus melas), and bluegill (Lepomis macrochirus). Bass only stocking was also evaluated. First eyar survival values for 16 eastern South Dakota ponds ranged from 1 to 100%, with a mean of 50.2%. Bass exhibited poorest survival when stocked with black bullheads. Analysis of variance indicated no significant difference (P …
