Pasture Condition Guides For The Pilbara, A L. Payne, A A. Mitchell

Agriculture reports

These pasture condition guides are relevant to about 192 000 square kilometres of the Pilbara region of Western Australia. The rangeland of the Pilbara can be separated into 12 very broad pasture types. The ‘pasture type’ is not strictly a botanical classification because, in determining such a class of pastoral lands, the perennial plant species that contribute to stock production have an over-riding importance. Even so, each pasture type represents a broad group of similar vegetation associations or ‘site types’ which will have similar management requirements for pastoralism. The aim of this publication is to provide pastoralists with descriptions and …

A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer

School of Natural Resources: Dissertations, Theses, and Student Research

The need to accurately assess the use and suitability of elk (Cervus elaphus spp.) habitat at regional scales will continue to increase as human development encroaches into what was once optimum elk habitat. The objectives of this research were to calculate the relative proportions of habitat use by elk in the Pine Ridge region of Northwestern Nebraska from a set of radio-collared elk locations and generate a habitat suitability model. Habitat variables (Iandcover type, aspect, slope, distance to a road, road density, and distance from the ponderosa pine edge) were measured for each elk location (n = 5,787 dating …

Comparison Of Water Quality, Zooplankton Density, And Cover In Razorback Sucker (Xyrauchen Texanus [Abbott]) Spawning Areas Of Lake Mead And Lake Mohave, Michael E. Golden, Paul B. Holden, Southern Nevada Water Authority

Publications (WR)

Las Vegas Bay and Echo Bay in Lake Mead have small, self-sustaining populations of razorback sucker (Xyrauchen texanus [Abbot]). Increased productivity and cover have been hypothesized as reasons for successful recruitment of razorback sucker in Lake Mead. Conversely, reproduction has been documented on Lake Mohave, another lower Colorado River reservoir, but no recruitment has been observed. In 2000, BIO-WEST, Inc. was contracted by the Southern Nevada Water Authority to design and implement a study to examine nutrient levels, zooplankton density, and cover in areas with and without razorback sucker recruitment success. We sampled Echo Bay, Las Vegas Bay, and …

The Pollinator Fauna Of Two Spring Wildflowers Of Midwestern Deciduous Forest, Erigenja Bulbosa And Claytonia Virginica, Robert P. Jean

All-Inclusive List of Electronic Theses and Dissertations

Eastern deciduous forests have spectacular spring floral display and a diverse array of insect pollinators. From March to May, some 20-25 species of understory herbs flower in west-central Indiana. I focused on the earliest species to bloom, Erigenia bulbosa (Apiaceae), and the most abundant, Claytonia virginica (Portulacaceae), which flowers immediately after Erigenia. l characterized insect visitor assemblages in terms of species richness and relative abundance, and measured visitation rates. For Erigenia (Chapter 1), I asked whether early flowering was necessarily associated with pollinator scarcity. I examined six sites in 2000 and resampled three of these in 2001. Erigenia attracted 10 …

Smart Growth And Land Acquisition Priorities, New England Environmental Finance Center

Land Conservation

It is well-known and generally accepted that all undeveloped land in New England cannot forever be protected from development; nor would this be a desirable goal, as continued economic development and population growth are near certainties. For these and other reasons, private land trusts and government agencies generally use explicit criteria to prioritize their land acquisition activities and prospects.

Much land protection in New England and elsewhere, however, has occurred without substantial attention to such land use needs as fostering the best locations for where people will live, businesses will locate, and infrastructure will be built to avoid degrading resources. …

Fisheries Research Report No.131 - Pilchard (Sardinops Sagax) Nursery Areas And Recruitment Process Assessment Between Different Regions In Southern Western Australia, Daniel J. Gaughan, Graeme Baudains, Ronald W. Mitchell, Timothy I. Leary

Fisheries Research Reports

Pilchards have been the primary target of purse seine fisheries along the south and lower west coasts of WA for nearly 15 years. Western Australia’s pilchard population consists of separate west coast and south coast breeding stocks. The adult pilchards in the south coast stock can, in turn, be further divided into three separate assemblages. These adult assemblages correspond to the purse seine fisheries at Albany, Bremer Bay and Esperance. However, while the separateness of the adult assemblages is well established, the status of the juveniles within the context of these adult groups is not understood. For example, the habitats …

Fisheries Research Report No. 137 - Annual Report On The Monitoring Of The Recreational Marron Fishery In 2000, With An Analysis Of Long-Term Data And Changes Within This Fishery, Brett Molony, Chris Bird

Fisheries Research Reports

This report presents the data from the 2000 season and compares the results with previous records. Although the 2000 marron season was relatively successful compared to the 1999 season it was still modest in terms of the historical records. Further, the recreational marron fishery continues to be declining in terms of catch rate, CPUE and other indicators derived from four data sources. The discussion highlights the variable nature of marron populations and the possible causes of the very different population structures of marron within the fishery. Further, possible reasons for the long-term decline of the marron fishery are discussed. It …

Use Of High Pressure Liquid Chromatography To Detect And Quantify Oxytetracycline Marks In Walleye Otoliths And Dorsal Spines, Michael J. Hawkins

Electronic Theses and Dissertations

Oxytetracycline (OTC) is used to chemically mark calcified structures in walleye Stizostedion vitreum fry and fingerlings. Current visual methods for detection of these marks are subjective, and biologists are unable to quantify the amount of OTC in a sample. The goal of this study was to determine if high pressure liquid chromatography (HPLC) is a feasible and superior alternative for detecting and quantifying OTC in otoliths of fry-marked and spines of fingerlingmarked walleyes. Study objectives were to validate methodology of extraction of OTC from calcified tissue, detect and quantify extracted OTC using HPLC, and determine a cost comparison of current …

Weed Plan For Western Australia, State Weed Plan Steering Group, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

One of the most significant environmental challenges facing Western Australia is the minimisation of the impact of weeds. In the relatively short history of this State since European settlement, some 1155 exotic plant species have established as weeds in our diverse and generally fragile ecosystems. While development for agriculture, mining, transport and housing must by its nature result in some change to the State’s flora, the introduction of weedy plant species has caused serious impacts which cause great concern.

Weeds now pose a serious threat to many of the State’s ecosystems, and impose high annual costs on agricultural industries. Weeds …

China and Taiwan are the major producers of cultured abalone; with annual production estimated at 3,500 and 3,000 tonnes respectively. The world production of cultured abalone sold in 1999 was 7,775 tonnes. Australian farm production was still relatively low (89 tonne in 1999) but numerous abalone farms have been proposed and many have been constructed. On a national scale, Tasmania and South Australia are the major states involved in temperate abalone culture; however, new projects have commenced in Victoria and considerable interest exists in New South Wales. Pilot scale trials with tropical abalone aquaculture using the Donkey-ear abalone (Haliotis asinina) …

Fish Protection Measures To Ensure Fish For The Future, Jo Bunting

Fisheries Management Papers

The protection of Western Australia's aquatic animals, plants and habitats is important for many reasons. Fish, and many aquatic invertebrates, have significant commercial, recreational and social importance. Aquatic habitats provide food, refuge and breeding areas for fish and other animals. In addition, some habitats, such as rocky reefs and seagrass meadows, act as nursery sites for juvenile animals. Some habitats and their inhabitants (such as coral reefs) also have aesthetic values which support economically and socially important industries, such as tourism.

Miscellaneous Publication 009/2001 - Pistachios Western Australia An Income Producing Reforestation Opportunity For The Wheatbelt, Andrew Quinn

Horticulture published reports

Faced with a rising water-table, salt and acid land impacts, the Western Australian Wheatbelt requires significant changes to traditional farming system models.

Part of this drive towards improved sustainability is the need to re-plant substantial areas to tree belts or blocks. One of the limiting factors in the widescale adoption of on-farm tree planting is the narrow range of opportunities to generate income from these sites.

This report presents a model for the development of a Pistachio nut industry with production integrated into existing Wheatbelt farming systems. In addition to offering significant environmental benefits, the Pistachio tree offers the opportunity …

Natural History And Roosting Ecology Of The Eastern Pipistrelle, Pipistrellus Subflavus, Jacques Pierre Veilleux

All-Inclusive List of Electronic Theses and Dissertations

A study concerning the natural history and roosting ecology of the eastern pipistrelle, Pipistrellus subtlavus, was conducted from 1997 to 2000, in southern Vigo County, Indiana. 111 Females began forming pre-maternity colonies during early May, and parturition began during late June. Pre-maternity colonies averaged 3.7 ± 1.9 individuals, and maternity colonies averaged 4.4 ± 2.4 individuals. Young pipistrelles first became volant during the third and fourth weeks of July. Pipistrelles were located in 59 roost trees. All roosts were located in foliage, either in clusters of dead leaves (n = 40) or in live foliage (n = 19). Oaks (Ouercus …
