Fisheries Research Report No 88 - A Synopsis Of The Biology And The Exploitation Of The Australiasian Pilchard, Sardinops Neopilchardus (Steindachner) Part 1: Biology, W. J. Fletcher
Fisheries Research Reports
There have been a large number of studies which relate to the biology and exploitation of the Australian pilchard, Sardinops neopilchardus. Much of the data, however, are located in journals which are hard to obtain, or in unpublished reports, and theses. With the increase in catch of pilchards, particularly in Western Australia, a collation of all the available knowledge pertaining to pilchards in Australia and New Zealand was desired to help with the planning of future research into the Western Australian stocks of this species. This report contains all the information located on the biology of Sardinops neopilchardus, a companion …

On March 25, 141 were arrested as part of the largest demonstration yet against the drilling of geothermal wells in the Wao Kele O Puna Rainforest on the Big Island of Hawaii. The geothermal project, undertaken by True Geothermal Company and endorsed by Hawaii's governor and other high-powered, short-sighted people, has already invaded the largest intact tropical lowland rainforest in the United States. The demonstration drew over 1500 protesters,
Changes To Simulated Fire Behaviour And Societal Benefits After Two Levels Of Thinning In A Mixed-Conifer Wildland-Urban Interface Community, Christopher Dicus
Changes To Simulated Fire Behaviour And Societal Benefits After Two Levels Of Thinning In A Mixed-Conifer Wildland-Urban Interface Community, Christopher Dicus
Natural Resources Management and Environmental Sciences
Potential fire behaviour and various societal benefits (air pollution removal, carbon sequestration, and stormwater runoff) were quantified in a California Sierra mixed-conifer forest in (a) untreated conditions, (b) after removing all understorey trees dbh, and (c) after thinning 50% of the stand's total basal area. Potential fire behaviour was modelled under constant conditions near a hypothetical development by the FARSITE fire behaviour and growth simulator and societal benefits were calculated by CITY green, both GIS-based software applications. Results showed that fire behaviour was considerably moderated by both thinning treatments. Modelled societal benefits, however, were largely unaffected by either treatment, which …
Alternatives To Fisher's "Exact Test" For Analyzing 2 X 2 Tables With Small Cell Sizes, Richard M. Engeman
Alternatives To Fisher's "Exact Test" For Analyzing 2 X 2 Tables With Small Cell Sizes, Richard M. Engeman
United States Department of Agriculture Wildlife Services: Staff Publications
Rice (1988a) presents an interesting test for analyzing 2 X 2 contingency tables in the smaller sample size situations. His motivation was to provide an alternative to Fisher's "exact test" and his rationale was based on the application of a prior distribution to the probability of a success, 0, under the null hypothesis. We would like to briefly comment on these aspects of his paper and also discuss another alternative that was proposed a number of years ago.
Bird Control On Containment Pond Sites, Lee R. Martin, Sam Hagar
Bird Control On Containment Pond Sites, Lee R. Martin, Sam Hagar
Vertebrate Pest Conference Proceedings: 14th (1990)
Bird deaths resulting from toxic materials in containment ponds are causing authorities to insist that action be taken to eliminate this hazard to avian wildlife. Bird control at containment pond sites is achieved by two well-known but poorly understood aversion techniques: hazing systems (sound/visual) and stretch wire. The limiting condition of either approach is that resident birds rapidly habituate while some migrating species are totally unaffected. Consequently, one must be able to accept degrees of control with an understanding of the behavior of the species involved. Birdproofing is achieved by covering an entire pond with bird net. This presentation discusses …
Wild Hog Management Program At Great Smoky Mountains National Park, John D. Peine, Jane Allen Farmer
Wild Hog Management Program At Great Smoky Mountains National Park, John D. Peine, Jane Allen Farmer
Vertebrate Pest Conference Proceedings: 14th (1990)
Over the last 30 years the wild hog population control program at Great Smoky Mountains National Park has experienced steady growth. The evolution has been relatively slow, and it was not until the latter part of the 1980s that sufficient funds were available to make a serious attempt at control measures. Over the years, the research program has focused on the biology of the wild hog; its reproductive rate; feeding and movement patterns; and its impact on the fauna, flora, and soils of the park. In addition, a major project was conducted to evaluate attractants and baits to increase the …

Rodenticide Ecotoxicology: Systems Analysis And Simulation, R.H. Smith, Paula R. Cox, M. Rampaud
Vertebrate Pest Conference Proceedings: 14th (1990)
Exposure, as well as toxicity, determines whether rodenticides present real environmental hazards to nontarget animals. In order to combine exposure and toxicity, a compartment model is proposed which distinguishes transfer processes from accumulation of residues. The published literature relevant to the model is analyzed, and some important gaps in knowledge are highlighted. Simple sub-models of rat feeding behavior and mortality are combined into a simulation model which generates data on both efficacy of control and build-up of residues in live rats and carcasses. The roles of feeding parameters (e.g., palatability, availability of alternative food) as well as toxicity are emphasized …
The Status Of The Steel Trap In North America, James H. Glass
The Status Of The Steel Trap In North America, James H. Glass
Vertebrate Pest Conference Proceedings: 14th (1990)
This paper will discuss strides taken to limit or eliminate use of the leghold trap and will explore recent trends in the animal rights movement's attack on fur and traps. A current legislative effort in Ohio, which seeks to protect wearers of fur and other animal products, as well as retailers, will be examined. Finally, the outlook as to what the future holds for the anti-trap debate and what we must do as responsible conservationists is discussed.
Vertebrate Pests Of Uk Agriculture: Present Problems And Future Solutions, Anthony R. Hardy
Vertebrate Pests Of Uk Agriculture: Present Problems And Future Solutions, Anthony R. Hardy
Vertebrate Pest Conference Proceedings: 14th (1990)
The status of damage by vertebrate pests to growing and stored agricultural crops is reviewed in the light of changing patterns of agricultural practice and land use within the UK. Significant problems and existing management techniques are briefly discussed. The results of recent research by the Agricultural Department and Advisory Service (ADAS) of the Ministry of Agriculture, Fisheries and Food are explored to indicate the future direction of vertebrate pest management to reduce crop damage. Recent changes in legislation and public attitudes impose constraints on some of the approaches to solving problems. The continued role of traditional control methods is …
Control Of The African Striped Ground Squirrel, Xerus Erythropus, In Kenya, Gillian E. Key
Control Of The African Striped Ground Squirrel, Xerus Erythropus, In Kenya, Gillian E. Key
Vertebrate Pest Conference Proceedings: 14th (1990)
The African striped ground squirrel, Xerus erythropus (E. Geoffroy), has been found to constitute a serious pest to maize seed at the planting stage, causing mean losses of 9.7% and accounting for 57.3% of total damage found. A feature of ground squirrel damage is its unpredictable nature. Methods of reducing losses of planted maize seed to X. erythropus at the subsistence farmer level in southern Kenya were investigated. Constraints affecting a control program by farmers were identified as follows: low standards of living and education, limited financial resources, strong individualistic attitude of farmers and small field size in relation to …
The Human Element In Wildlife Damage Situations, Ron J. Johnson
The Human Element In Wildlife Damage Situations, Ron J. Johnson
Vertebrate Pest Conference Proceedings: 14th (1990)
The field of prevention and control of wildlife damage is changing and evolving along with clientele needs, pressures from user and non-user groups, and other factors. A theoretical overview of the field may offer an action model regarding changing trends and potential responses. I propose that three things happen every time a wildlife damage problem occurs: 1) A human activity, desire, or need is interfered with, 2) the experience fosters an opinion about a wild animal - usually negative, and 3) a decision is made to tolerate the situation or to control it. If control is selected, availability and effectiveness …

Frightening Methods And Devices/Stimuli To Prevent Mammal Damage-- A Review, Ann E. Koehler, Rex E. Marsh, Terrell P. Salmon
Vertebrate Pest Conference Proceedings: 14th (1990)
Various frightening stimuli, primarily visual and acoustic, have been used to prevent or alleviate damage by depredating mammals (e.g., deer (Odocoileus spp.), raccoons (Procyon lotor), tree squirrels (Sciurus spp.), coyotes (Canis latrans). Frightening methods are most appropriate for use where a crop or situation needs protection from pest mammals for only a period of a few days or weeks. The ability of animals to habituate to such stimuli limits their long-term usefulness. Against nocturnal species, various types of lights and noisemakers are the most useful. Combining acoustic and visual stimuli can enhance effectiveness, while …

The Development Of A Policy For The Management Of Dingo Populations In South Australia, R. J. Downward, J. E. Bromell
The Development Of A Policy For The Management Of Dingo Populations In South Australia, R. J. Downward, J. E. Bromell
Vertebrate Pest Conference Proceedings: 14th (1990)
Competing concerns between conservation and sheep-growing interests in South Australia over problems associated with the naturalized dog,Canis familiaris dingo, prompted the development of a policy for the management of this subspecies. The background to the development of this policy is outlined. The policy provides for a compromise between the need to protect the livestock industry while ensuring the continued survival of the dingo as a wildlife species.

Juvenile rainbow trout Oncorhynchus mykiss. (ca. 80 mm S.L.) stocked into mid-elevation reservoirs in Utah are vulnerable to predation from piscivorous fish and birds. I determined how effectively juvenile trout used cover to avoid these predators by using direct observations (snorkel transects) on habitat selection in two reservoirs. Observations of juvenile trout were conducted within five weeks of stocking in 1988 and 1989. During the day juvenile trout were abundant in complex inshore habitats. Juvenile trout actively fed during the day but the time of peak feeding was variable. Large Daphnia made of > 95% of the diet of juvenile trout. …

If you feel, after your latest cruise through your research library, that you were adrift in a very expensive sea of paper, you are certainly not alone. As a researcher at a research university, it is very easy to use the resources of your library and to be confronted with the funding problems of that library only as those problems affect your particular area of interest. In recent years most researchers at universities have been told that subscriptions to journals will have to be cut in their area and that less of the library materials budget will be available to …

Can Kangaroos Survive In The Wheatbelt?, Graham Arnold
Journal of the Department of Agriculture, Western Australia, Series 4
One of the costs of agricultural development in Western Australia over the past 100 years has been the loss of most of the native vegetation and, consequently, massive reductions in the numbers of most of our native fauna. Thirteen mammal species are extinct and many bird and mammal species are extinct in some areas. These losses will increase as remnant native vegetation degrades under the impact of nutrients washed and blown from farmland, from the invasion by weeds and from grazing sheep.
Even kangaroos are affected. Unless the community manages remnant vegetation to minimise degradation and enhance the regeneration of …

The Sidney Gravel And Kimball Formation, Supposed Parts Of The Ogallala Group (Neogene), Are Not Objectively Mappable Units, Robert F. Diffendal Jr.
School of Natural Resources: Faculty Publications
In the 1930s. G. L. Lueninghoener and A. L. Lugn prepared geologic maps of several counties. including Kimball and Cheyenne in the southern Nebraska Panhandle. for the Nebraska Geological Survey. Rock units designated as the Kimball Formation and the underlying Sidney Gravel were shown on these maps. Studies by Swinehart (1974). Breyer (1975; 1981). and Diffendal (1985) demonstrated that these units could not be defined in several areas in western Nebraska. Results of this study show clearly that the Kimball Formation and Sidney Gravel cannot be traced for more than a few kilometers from their type areas.

Fisheries Research Reports
It is generally acknowledged that more competitive marketing of Australian fisheries and aquaculture harvests requires closer attention to post-harvest technology. Historically, these products have been marketed in a variety of forms (e.g., for freshwater crayfish:- boiled fresh, boiled frozen, whole or tails, and live). Some of these forms present a product of actual, or perceived, poorer quality to the retailer and consumer and, thereby, obtain low prices.
Freshwater crayfish can survive out of water for extended periods and, so, can be economically transported alive to the (overseas) restaurant chef. This live product commands the very highest price for the grower. …
