The Federal Land Policy and Management Act (Summer Conference, June 6-8)
Conference organizers and/or faculty included University of Colorado School of Law professors James N. Corbridge, Lawrence J. MacDonnell, David H. Getches and Charles F. Wilkinson.
This important piece of legislation, passed by Congress in 1976 following many years of extensive study and debate, directs the activities of the nation's major land manager--the Bureau of Land Management. The FLPMA conference will bring together a distinguished group of experts to review the law itself, to consider the effectiveness with which it has been implemented, and to discuss the key issues which have arisen under its implementation.

Sunlight And Plants, Some Pursuits In Physiological Ecology, Martyn M. Caldwell
Faculty Honor Lectures
A physiological ecologist, as the name suggests, focuses on the interface between plant physiology and the ecology of individual organisms. Yet, one in this field should know something about disciplines ranging from physiology, or in the case of the subject of this lecture, even photochemistry, to the study of entire ecosystems.
A Bacteriological And Chemical Analysis Of Nonpoint Source Pollution In A Karst Aquifer Bowling Green, Kentucky, Wayne Green
A Bacteriological And Chemical Analysis Of Nonpoint Source Pollution In A Karst Aquifer Bowling Green, Kentucky, Wayne Green
Masters Theses & Specialist Projects
Monthly water samples collected from four sites in the Lost River Groundwater Basin, a shallow karst aquifer in the Bowling Green-Warren County area of Kentucky, represented samples from sites receiving conduit and diffuse flow. All sites were severely contaminated with bacteria, and on some occasions the surface water criteria for some heavy metals were exceeded.
Of the total 334 bacterial colonies identified 92.1% were verified as Escherichia coli by the API20E system. Acinetobacter calcoaceticus var. anitratum accounted for 2.10% of colonies; Citrobacter freundii for 0.30% Klebsiella pneumoniae for 0.90%; Klebsiella oxytoca, 0.90%; Citrobacter amalonaticus 0.30%; Enterobacter cloacae, 1.20%; …
Seasonal And Spatial Heterogeneity In The Limnetic Zooplankton Community Of Lake Mead, Gene Robert Wilde
Seasonal And Spatial Heterogeneity In The Limnetic Zooplankton Community Of Lake Mead, Gene Robert Wilde
Publications (WR)
Zooplankton samples collected from throughout Lake Mead, in 1981-1982, demonstrate the presence of a statistically significant seasonal and spatial heterogeneity in zooplankton densities. Seasonally, the major zooplankton groups were most abundant in the spring and fall, coincident with maxima in chlorophyll-a concentrations. Successions among the various rotifers, cladocerans and copepods present in the reservoir were influenced by food availability, diapause, predation by planktivorous fish and, possibly, water temperatures. Spatial heterogeneity in zooplankton densities was unrelated to water temperature, pH, conductivity and dissolved oxygen concentrations, but was related to the abundance of phytoplankton (chlorophyll-a concentrations) and fish. Statistical analyses indicate that …
The Role Of Nannoplankton In The Phytoplankton Dynamics Of Four Colorado River Reservoirs (Lakes Powell, Mead, Mohave, And Havasu), Jeffrey John Janik
The Role Of Nannoplankton In The Phytoplankton Dynamics Of Four Colorado River Reservoirs (Lakes Powell, Mead, Mohave, And Havasu), Jeffrey John Janik
Publications (WR)
Phytoplankton species composition and community size structure were studied in four warm-monomictic Colorado River reservoirs; lakes Powell, Mead, Mohave, and Havasu from March 1981 to February 1982. Sampling was done at approximately monthly intervals from several stations in each reservoir. The Utermohl technique was used to enumerate phytoplankton. The phytoplankton assemblage was divided into the following six size classes using microscopic techniques; netplankton (>64 um), and nannoplankton (>5, 5-11, 12-21, 22-44, and 45-64 um).
Total phytoplankton biomass and community size structure were different among these four reservoirs with considerable spatial and temporal variation present. Average reservoir-wide areal weighted …

Las Vegas Wash Multispectral Scanner Survey, T. H. Mace, M. V. Olsen, Environmental Protection Agency
Publications (WR)
At the request of the U.S. Bureau of Reclamation, Boulder City, Nevada, the U.S. Environmental Protection Agency's Environmental Monitoring Systems Laboratory at Las Vegas collected multispectral scanner imagery of Las Vegas Wash on October 1, 1982. A combined maximum likelihood classification and editing procedure was used to classify the multispectral scanner imagery into 12 categories of land cover. The classification identified four categories of marsh vegetation, one category of riparian, two categories of mixed scrub, and two desert categories. Turbid water and cultivated land formed an "other" category. Area tabulations were formed by georeferencing the classification to the Universal Transverse …

Fisheries Report No 66 - The Fishery For Perth Herring, Nematalosa Vlaminghi (Munro), C F. Chubb, N. G. Hall, R C.J. Lenanton, I. C. Potter
Fisheries Research Reports
Perth herring fishery over the last 30 years have been examined. While there are pockets of catches between Broome and Bunbury, those from the Swan Estuary and nearby inshore marine waters make by far the most important contribution to the fishery. In the Swan Estuary, the catches started rising in the 1950s in response to a demand by the rock lobster industry for bait and reached peak values in the late 1960s and early 1970s. Data are provided which demonstrate that catch per boat is a good index of catch per unit effort (CPUE) in the period since 1967 when …

Fisheries Report No. 65 - The Amateur Fishery For Marron (Cherax Tenuimanus) In Western Australia - Summary Of Logbook Data 1971-83, N. Morrissy, C. Fellows, N. Caputi
Fisheries Research Reports
The large, native crayfish called marron, Cherax tenuimanus, supports an extensive recreational fishery in the southwest of Western Australia. This report examines annual catch and effort statistics gathered from a Logbook programme, initiated in the 1971/72 season and supplemented by an end of season telephone survey from 1977. Logbook data gave estimates of relative abundance, but were too biased for projection to total catch and effort for the fishery, while telephone surveys gave unbiased estimates of total annual fishing effort (trips)l.
Relative abundance showed a significant decline in the major rivers and the most popular dam (Wellington) over the monitoring …

Fisheries Report No 60 - Amateur Net Fishing Survey Of Two Western Australian South Coast Estuaries In January 1981, D. I. Heald
Fisheries Research Reports
Following the return of the administration of fishing activities in Wellstead estuary and Beaufort Inlet to the Western Australian Government in October 1980, a survey of the amateur net fishing in these two estuaries was undertaken in January 1987, The purpose of the survey was to document usage, species catches and size composition of fish caught in respect of mesh size used and the success rate of amateur net fishermen as compared to their expectation. At the time of the survey, Wellstead estuary had been closed to the sea for 13 months and Beaufort Inlet for 27 months and the …
Fisheries Report No 63 - Assessment Of Artificial Feeds For Battery Culture Of A Freshwater Crayfish, Marron (Cherax Tenuimanus) (Decapoda: Parastacidae), Dr N. Morrissy
Fisheries Research Reports
Performance of juvenile crayfish, 0.1-5 g, on a variety of commercial crustacean feeds was tested under conditions of individual housing ("battery culture"), where sources of additional feed were minimized (detritus), or eliminated (cannibalism) Survival was close, or equal, to 100% over 50 day test periods, a reflection of optimal battery conditions rather than feeding, since survival over 100 days for an unfed (control} group was also 100%. No ecdysiad mortality, or trauma, occurred with crayfish, up to 10g, in compartments of area 75 cm. Growth performance in tests was rated by separate ratios for ecdysial increment and frequency, relative to …

Fisheries Report No 64 - The Western Rock Lobster Fishery 1977 - 1978, 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. 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 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 ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably …

Fisheries Report No 67 - The Western Rock Lobster Fishery 1978 - 1979, 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 a record 11 388 tons in 1978/79, out of a total Australian catch of rock lobster of 15 400 tons. 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 …

Fisheries Report No 62 - The Commercial Fisheries Of Temperate Western Australian Estuaries: Early Settlement To 1975, R C.J. Lenanton
Fisheries Research Reports
This report provides a quantitative description of the commercial estuarine fisheries of temperate Western Australia. An account is given of the Long series of historical events which influenced the development of the fisheries and led to their current status. All available catch and effort data covering the years 1898 - 1975 are presented. The use of this long series of historical catch and effort data as an aid to the management of the estuarine fisheries resources is discussed. It is emphasised that interpretations of these data cannot be undertaken effectively without a knowledge of factors such as Life history strategies, …

Research Objectives In Vertebrate Pest Control, A J. Oliver
Research Objectives In Vertebrate Pest Control, A J. Oliver
Journal of the Department of Agriculture, Western Australia, Series 4
The European rabbit, introduced into Australia in 856 by an early settler for hunting, caused massive losses to agricultural production in Western Australia in 1940s and 1950s.
In those years most of the country's recources and efforts allocated to vertebrate pest problems were aimed at controlling this animal.
Research and control measures by Commonwealth and State agencies, including the introduction of myxomatosis, were largely responsible for reducing the rabbit problem to the comparatively minor one it is now.
Today, the Agricultural Protection Board is involved in the control of a much wider range of mammals and birds which cause losses …

Alternative Land Uses, D A. Morrison, B. C. Mattinson
Journal of the Department of Agriculture, Western Australia, Series 4
One aproach to minimise the high nutrient content and associated algal pollution of the Peel-Harvey estuarine system is to reduce phosphorus losses at their source. Farmers can do this by changing land use is such a way thar phosphorus run-off fromthe catchment soils into drainage is prevented or at least reduced.
The department of Agriculture is investigating the economics of alternative uses, particularly substituting forestry with Pinus pinaster or Eucalyptus globulus (Tasmanian blue gum) for present beef and sheep enterprises. P. pinaster is used for logging and E. globulus for pulping.
Rabbit Kitten Survival In The South-West, D R. King
Rabbit Kitten Survival In The South-West, D R. King
Journal of the Department of Agriculture, Western Australia, Series 4
In the South-West of Western Australis reliable winter rains allow the rabbit breeding season to extend through winter and spring, and thus a large number of kittens are produced each year.
Studies on the biology of rabbits at Cape Naturaliste (270 kilometres south-west of Perth) and Chidlow (40 kilometres east of Perth in the Datling Range) have shown that at these sites each doe produces about 30 and 27 kittens respectively a year. If all these youg rabbits survived, there would be a 15-fold increase in numbers. Within a short time the State would be covered "wall to wall" by …

Rabbits North Of Carnarvon, D R. King
Journal of the Department of Agriculture, Western Australia, Series 4
In Westeern Australia rabbits are mainly a pest along the south-western coastal parts of the State, but there are populations north of the Tropic of Capricorn. Rabbits after crossing the Nullarbour plain from South Australia and colonising the South-West of the State, were reported to have reached the west coast near Geraldton by 1912 and then spread northwards.
There is little information on the biologhy of rabbits in the northan parts of their range, but pastoralists in some areas are concerned about erosion and damage to vegetation on their stations when rabbits reach high numbers.
The Agricultural Protection Board undertook …
