Growth Characteristics Of Reef-Building Corals Within And External To A Naval Ordinance Range: Vieques, Puerto Rico, Richard E. Dodge
Growth Characteristics Of Reef-Building Corals Within And External To A Naval Ordinance Range: Vieques, Puerto Rico, Richard E. Dodge
Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures
The skeletal growth of reef·building corals is known to be sensitive to the environment. In particular, high levels of sedimentation and turbidity lead to decreased growth rate, suppressed growth variation, and, ultimately, coral death because of reduced illumination necessary to zooxanthellae and/or increased energy expenditure by the coral animal to remove impacted sediments.
To assess the effect of Naval Ordnance Range usage at Vieques, Puerto Rico, specimens of Montastrea annulariswere collected from reefs adjacent to and removed from the range area. Growth was measured from annual increments revealed by X-radiography of medial slabs of the coral skeletons. Mean growth …
Report No 47 - 1980 Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro
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 …

Fisheries Report No 44 - The Birds Of Pelsart Island Western Australia, Phillip J. Fuller, Andrew A. Burbidge, A. G. Wells
Fisheries Research Reports
Between 1977 and 1981, 58 species of birds were recorded at Pelsart Island. Fifteen sea birds and one land bird were recorded breeding
Pelsart Island is one of the most important sea bird breeding islands in Australia and the World. Birds of special significance which breed there include the Lesser Noddy Anous tenuirostris, the Common Noddy Anous stolidus, the Sooty Tern Sterna fuscata, the Osprey Pandion haliaetus and the White~breasted Sea-eagle Haliaeetus leucogaster. The Lesser Noddy colony disappeared between 1899 and 1907 during a period of intense guano mining. It re-established sometime between 1913 and 1936 and since 1954 it …

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 …

Mit zwei großen komplexen biologischen Sammelexpeditionen 1962 und 1964 der Akademien der Wissenschaften der DDR und MVR in die Süd- und Westmongolei wurde der Grundstein für die kontinuierliche Entwicklung der Wissenschaftskooperation auf biologischem Gebiet zwischen beiden Staaten gelegt. Die Kollektionen wurden zum Grundstock eines aufzubauenden botanischen und zoologischen Sammlungsfundus in Ulan-Bator. Durch den Freundschaftsvertrag zwischen den Universitäiten Halle und Ulan-Bator im Jahre 1967 wurden die Kontakte neu aktiviert. Nach anfänglich sporadischen Studienaufenthalten und Expeditionsreisen von Einzelwissenschaftlern wurde das Forschungsprogramm auf biologischem Gebiet im Rahmen dieses Freundschaftsvertrages recht bald auf Schwerpunktaufgaben ausgerichtet, die sich lückenlos in das Forschungsprofil des mongolischen Vertragspartners …

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 …

Home Range, Home Range Expansion, Dispersal, And Mortality Of Juvenile Red Foxes In Southeastern South Dakota, Floyd M. Demaray
Electronic Theses and Dissertations
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 …
Field Preparation For Pasture Renovation, Harold B. Rice
Field Preparation For Pasture Renovation, Harold B. Rice
Soil Science News and Views
Grassland renovation is the improvement of pasture and hay fields by partial destruction of the sod, plus liming, fertilizing, and seeding as may be required to establish or re-establish desirable forage plants without an intervening crop. In Kentucky, this improvement has been primarily through the seeding of legumes such as clovers and alfalfa into grass sods.
Since liming and fertilizing are essential steps in pasture renovation the FIRST step is to have your soil tested to determine how much lime and plant nutrients to apply. Seedbed preparation will range from none to complete disturbance of the existing sod depending on …

The Quality Outdoor Recreation Component In Multi-Purpose Conservation Areas: A User Assessment Devised, And Applied To Pinehurst Lake Conservation Area, Gerald Carl Thomas
Theses and Dissertations (Comprehensive)
Recreational demand for out-of-doors space and facilities continues to increase into the 1980’s. Accordingly, multi-purpose conservation areas, by the nature of their designations, require ongoing assessment of the attributes which determine the quality of the recreational experience they afford.
A problem with the master planning process for these multi-use areas is that in the past, little or no consideration has been given to user-recreationist input in the development stages of the master plans. The purpose of this study is to devise a method of assessing user satisfaction towards the recreational quality available at multi-use conservation areas, and to show how …
