Fisheries Report No 14 - Wilson Inlet - A Seasonally Closed Western Australian South Coast Estuary, R C.J. Lenanton

Fisheries Research Reports

Considerable conflict has existed for many years between professional fishing, recreational usage and development in the west and south coast estuaries of Western Australia. One of the areas where intense conflict exists is Wilson Inlet.

The Government's task of advising the various interests concerned in these conflicts has been difficult, due to the lack of knowledge of estuarine fauna and environment in relation to usage and development.

The objective of this report is to present a preliminary description of the Wilson Inlet environment, to record the history of netting closures in the Inlet, and to discuss the history of the …

Microfossils From The Upper Severy Shale (Pennsylvanian) Near Dubois, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Organic rich limestone nodules within the Severy Shale Formation collected directly above the Nodaway Coal Member near DuBois, Nebraska, have yielded a rich microflora and microfauna. The microflora includes Triletes megaspores, seeds, cuticle, and pieces of wood with well preserved structures. The microfaunal skeletal material is either partially or completely replaced by pyrite, marcasite, or, in rare cases, by sphalerite. The following major invertebrate groups and genera within these groups have been identified to date: Bryozoa (one undetermined genus); Brachiopoda (Juresania) ; Gastropoda (four undetermined genera); Ammonoidea (one undetermined genus); Ostracoda (Amphissites, Coryellites, Hollinella, Macrocypris); Echinoidea (five spine types); and …

Finitely Generated Modules Over Bezout [email protected], Roger Wiegand, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Let R be a Bezout ring (a commutative ring in which all finitely generated ideals are principal), and let M be a finitely generated R -module. We will study questions of the following sort: (A) If every localization of M can be generated by n elements, can M itself be generated by n elements? (B) If M 0 R m = Rn for some m, n, is Af necessarily free? (C) If every localization of M has an element with zero annihilator, does M itself have such an element? We will answer these and related questions for various familiar classes …

Automation Of The Continuous Coagulation Monitor, Dee Mitchell, James J. Oskowis

Arkansas Water Resources Center Technical Reports

The development of automation in the past 50 years has paralleled the accelerating growth of today’s vast technological society. Automatic control systems are indispensable extensions of man's brain that enable him to monitor and regulate his complex environment. The principles of automatic control have a wide range of applications and interests in virtually every scientific field. The need for automatic control systems in vital applications of environmental engineering is both real and urgent. Extensive pollution has resulted in unavoidable water re-use and in the inevitable establishment of stringent effluent standards. Both water and wastewater treatment processes have necessarily become more …

Environmental Evaluation Report On The Big Mulberry Creek Basin In Franklin, Madison, Newton, Johnson And Crawford Counties, Arkansas, Edward E. Dale Jr.

Arkansas Water Resources Center Technical Reports

The environmental evaluation report which follows is based on information supplied by the Corps of Engineers, Little Rock District, available literature, field observations made during the summer of 1972, and results of research now in progress on natural features of the Big Mulberry Basin. Since most major dams, levees, and flood retarding structures now in existence in the Ozarks have been constructed since about 1940, opportunities to make long term studies of their effects have been limited. Also, the natural vegetation, fauna, and archeology of the Big Mulberry Basin have not been extensively investigated, but available sources provide enough information …

Fisheries Report No 15 - The Western Rock Lobster Fishery 1972 - 1973, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total 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 ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. Inherent …

Conservation Of The National Estate, Department Of Agriculture, Western Australia

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

In 1973 the Australian Government established a Committee of Inquiry under Mr. Justice R. M. Hope to inquire into the National Estate. Under its terms of reference the Committee was to assess the nature and condition of the National Estate and the measures which were being and should be taken for its preservation and enhancement.

Officers of the Department of Agriculture recognise that there are basic natural resources such as land, water, gene material and ecosystems which are essential elements of the National Estate held in trust by successive generations.

In a submission to the Inquiry, matters of particular concern …

Pheasant Reproduction And Survival As Related To Agricultural Fertilizer Use, Lawrence Francis Fredrickson

Electronic Theses and Dissertations

Wing-clipped wild pheasants (Phasianus colchicus) were stocked in 1-acre and 0.5-acre pens having oat and bromegrass cover in 1972 and 1973 to test effects of fertilizer (Formulations: 34-0-0, 18-46-0, 0-46- 0, and 0-0-60) on pheasant reproduction and survival. One-half of the pens were fertilized with the recommended rate of pelleted fertilizer and the other half without fertilizer. Complete nest searches in July showed that nesting success was not significantly different (P>0.05) between treatments for both years. No significant difference (P>0.05) was found in clutch size or in number of ovulated follicles from control and experimental hens. Significantly more …

The learning behavior of penned white pelicans (Pelecanus erythrorhynchos) was studies 2 August to 5 October 1972 using a swimming pool – Y-maze apparatus in an operant conditioning experiment. The experiment consisted of three consecutive phases: trial-and-error learning, extinction, and relearning. Three groups of nine pelicans each were studied: a polychlorinated biphenyl (PCE) treated group, a DDT, DDD, DDE treated group, and a Control group. The object of this study was to determine the effect of PCB and DDT, DDD, DDE on the learning ability of penned white pelicans. Control, PCB, and DDT groups of penned white pelicans learned to …

Habitat Preferences And Food Habits Of Striped Skunks In Eastern South Dakota, Melvin S. Moe

Electronic Theses and Dissertations

Habitat preferences of striped skunks (Mephitis mephitis) in Brookings County, South Dakota, were determined rom the relationship of nighttime roadside indices to 25 habitat variables of 277, 1-square mile plots. Winter tracking was also conducted. Skunks were collected on the study area in 1972-1972, and contents of 59 stomachs and 63 colons were studied to determine food habits. Indices of prey abundance in different habitat types were obtained from snap-trap surveys. The 25 variables accounted for 14.9 percent of the variation in skunk numbers. The relationships of three of these variables to skunk numbers were significant (P<0.05). The significant variables and the variation accounted for by each were: (a) number of areas of idle grassland, 6.3 percent; (b) number of rockplies, 1.5 percent; and (c) acreage of idle grassland, 1.3 percent. Idle grasslands were the main activity centers of skunks tracked during the winter. Food habits were analyzed for the periods March-April, May-June, July-August, and September-November. Insects were the most frequently found food item in al time periods except March-April, during which mammals occurred more frequently. Mammals made up the largest volume of food in March-April and May-June. Amphibians made up the greatest volume in July-August, while amphibians, mammals, and insects were found in nearly equal volumes in September-November. Bird remains occurred during all time periods. Eggs were found in May-June and July-August. Meadow voles (Microtus spp.), the most frequent mammalian food item during all time periods, were common only in habitat types having heavy residual cover. Idle grassland is an important nestling cover for gamebirds and waterfowl. Since the number of areas of this cover type apparently has a stronger relationship with skunk numbers than its total acreage, grassland nesting cover might best be managed in large, homogeneous blocks. Areas managed in this way would probably support lower skunk densities than more diverse areas containing equal acreages of idle grassland, thus reducing nest predation by skunks. Skunk control programs should be most efficient when centered around idle grassland and rockplies.

Influence Of Vegetation On The Distribution Of Small Mammals On A Waterfowl Production Area, Douglas A. Searls

Electronic Theses and Dissertations

. A study was conducted on a Waterfowl Production Area in Brookings County, South Dakota in 1972-73 to determine the distribution and abundance of small mammals. Three cover types, reseeded native grassed, brome-alfalfa, and bluegrass, were studied. Meadow voles (Microtus pennsylvanious), and deer mice (Peronyscus maniculatus) were captured most frequently. Jumping ice (Zapus hudsonius), masked shrews (Sorex cinerius), short tailed shrews (Blarins brevicauda), grasshopper mice (Omychomys leucogaster) and house mice (Mis musculus) were also taken. The bluegrass association had the highest number of small mammal captures and the reseeded native grass association has the least. There was no significant difference …

Evaluation Of Duck Production On Waterfowl Production Areas In Northeast North Dakota, Gerald L. Heismeyer

Electronic Theses and Dissertations

An investigation of duck production on six Waterfowl Production Areas (WPA’s) in northeastern North Dakota was conducted during 1970-73. This investigation was conducted in conjunction with habitat-manipulation study by the Northern Prairie Wildlife Research Center that entailed prescribed burning of three WPA’s. Wetland habitat conditions, breeding populations and nesting were evaluated all four years. Brood observations were made during the last three years and nesting cover was evaluated during the last two years of investigation. Wetland habitat conditions were generally favorable during the first three years of investigation but in 1973 wetland conditions were extremely poor due to low precipitation …
