Douglas-Fir Beetle (Dendroctonus Pseudotsugae Hopkins, Coleoptera : Scolytidae) Brood Production On Douglas-Fir Defoliated By Western Spruce Budworm (Choristoneura Occidentalis Freeman, Lepidoptera : Tortricidae) In Logan Canyon, Utah, S E. Fredricks, M J. Jenkins

The Bark Beetles, Fuels, and Fire Bibliography

Douglas-fir beetle brood production was studied on Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) trees defoliated by the western spruce budworm between 1983 and 1985. Tallies were made of the number of attacks, total length and number of egg galleries, number of eggs deposited, number of larval tunnels, number of pupal chambers, and number of emerging beetles (per female and per unit area). Data analysis showed no significant differences among the three years studied. The number of emerging beetles per female parent was 0.59, and emergence per 90 cm2 was 2.32 beetles. Egg, larval, and pupal survivals were 47.5%, 30.0%, and 15.5%, …

Lodgepole Pine Vigor, Regeneration, And Infestation By Mountain Pine Beetle Following Partial Cutting On The Shoshone National Forest, Wyoming, Gene D. Amman, Gene D. Lessard, Lynn A. Rasmussen, Curtis G. O'Neil

The Bark Beetles, Fuels, and Fire Bibliography

Lodgepole pine stands were thinned in the Shoshone National Forest of northwestern Wyoming in 1979 and 1980 using different forms of partial cutting. Average losses of trees 5 inches diameter at breast height and larger to mountain pine beetles during the 5 years following thinning ranged from less than 1 percent in spaced thinnings to 7.4 percent in the 12-inch diameter limit cut, compared to 26.5 percent in check stands. Residual trees increased radial growth significantly, but change in growth efficiency is slow. Regeneration 5 years after thinning ranged between 1,160 and 3,560 seedlings per acre, with pine being favored …

An Inventory And Condition Survey Of Rangelands In The Ashburton River Catchment, Western Australia, A A. Mitchell, A L. Payne, W F. Holman

Technical Bulletins

The inventory and condition survey of rangelands in the Ashburton River catchment, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1976 and 1978, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed …

The South West Trawl Fishery Draft Management Plan., P. J. Millington

Fisheries Management Papers

This paper outlines a proposal for management of trawl fisheries operating in waters less than 200m deep between the Moore River north of Perth and Cape Leeuwin. Off Fremantle, potential and actual user conflicts between trawling and the requirements of recreational fishing and other forms of commercial fishing point to the need to gradually phase out trawling in this area. A limited entry fishery, with no licence transferability, is therefore proposed.

Sport Fishing For Marron In Western Australia - Management For The Future : A Discussion Paper On Management Options For The Marron Fishery., Fisheries Department Of Western Australia.

Fisheries Management Papers

The number of marron that may be caught each year without seriously jeopardising the long term future of fishery is limited. The situation deteriorated still further after another winter of low rainfall in 1987 and as the 1987-88 summer drew closer it became doubtful whether the State's marron stocks could withstand another season of hard fishing pressure. Thus, it was considered necessary to ban all fishing for marron during the 1987-88 season. This discussion paper has been prepared to help start the ball rolling in the right direction, and ensure any measures taken to safeguard the fishery are backed up …

Fisheries Management Paper No. 22 - Economics And Marketing Of Western Australian Pilchards., Scp Fisheries Consultants Pty Ltd

Fisheries Management Papers

Most of the Western Australian pilchard catch comes from King George Sound and from the southern coast off Albany where the number of vessels allowed to catch has been controlled. Prospects for increasing production in this area are limited. However, there are indications that considerable quantities of pilchards could be caught in waters to the east and west of Albany, in the inshore declared purse seine development zone.

Before allowing fisherman to catch more pilchards in these waters, the Western Australian Government decided that an investigation should be undertaken of the Australian pilchard resources, the domestic and export market situation …

A Comparative-Ecological Approach To The Study Of Learning, Alan Kamil, John E. Mauldin

Papers in Behavior in Biological Sciences

The purpose of this chapter is to discuss the effects of a parameter which is present in every learning experiment, but about which we know relatively little--the species being tested. The effects of the species variable have been studied relatively infrequently by animal learning psychologists for at least three reasons. (1) Psychologists have tended to assume that a few general processes will account entirely for most, if not all, of the important phenomena of animal learning in a broad range of species. This assumption has been criticized frequently in recent years (e.g., Seligman, 1970; Seligman & Hager, 1972), but still …

A Seasonal Comparison Of Metabolic And Water Loss Rates Of Three Species Of Grasshoppers, Lynn J. Forlow, James A. Macmahon

Green Canyon Environmental Research Area, Logan Utah

1. 1. Seasonal differences in metabolic and water loss rates were examined in three related species of grasshoppers collected from shrub-steppe communities in Utah: Arphia conspersa, A. pseudonietana and

2. 2 cohorts of Trimerotropis pallidipennis. 2. No significant differences (P = 0.05) in metabolic rates were observed between seasons (early vs late), between genera (Arphia vs Trimerotropis) nor among species.

3. 3. Early season (spring) grasshoppers had a higher (but non-significant) mean water loss rate (±X ± SD in mg.g−1-hr−1) (4.81 ± 1.53) than late season (summer) grasshoppers (4.43 ± 1.43).

4. 4. Among species, early season A. conspersa had …

Comments On Estimating Population Rate Of Increase From Age Frequency Data, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Although many papers have described assumptions and calculations of r from different kinds of data, none has compared estimates of r for the same real data set under different assumptions. We used the age distributions of gray foxes collected during six trapping seasons to estimate and compare r and lₓ series derived under different assumptions. Because trapped foxes are killed, they are believed by some to represent death history data. We found this treatment underestimates mortality so overestimates survivorship and leads to erroneous conclusions about the population. Use of a projection matrix allowed prediction of population size and thus allowed …

Incubation Energetics Of The Laysan Albatross, Ted N. Pettit, K A. Nagy, Hugh I. Ellis, G Causey Whittow

Biology: Faculty Scholarship

The energy expenditure of incubating and foraging Laysan Albatross (Diomedea immutabilis, mean body weight 3.07 kg) was estimated by means of the doubly-la- belled water technique. During incubation, the energy expenditure was similar to that of resting birds that were not incubating an egg. The energy expenditure of foraging albatross (2072 kJ/day) was 2.6 times that of resting birds. It was concluded that the energy expenditure of the tropical Laysan Albatross was not less than that of species foraging over cold, high-latitude oceans. An energy budget compiled for an incubating pair of albatross revealed that the energy expenditure of the …

Autumn Foods Of White-Tailed Deer In Arkansas, Thomas A. Nelson, Luke Eggering, Danny Adams

Journal of the Arkansas Academy of Science

Rumen contents from 65 hunter-harvested deer were collected and analyzed during 1985-86 to estimate the principal autumn foods consumed by white-tailed deer inhabiting the Ozark Mountains, Arkansas River Valley, and Gulf Coastal Plain regions of Arkansas. Deer in the Ozarks and Coastal Plain fed heavily on woody browse species, which comprised 99% of rumina identified from these 2 regions. Acorns were the primary food of deer in these heavily forested areas. Acorns and other woody browse were less important to deer inhabiting the Arkansas River Valley. In this region of interspersed agricultural fields and bottomland forests, soybeans and corn comprised …

Sex Ratios In Bobcat Populations, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Reported sex ratios in bobcat populations have suggested great variation ranging from strong male bias to strong female bias. Explanations offered for these observations have included factors of mobility, activity, behavior, inaccurate data collection, hunting pressure, and population density. Ratios are probably most representative during the winter, when females are no longer under constraints of parental care. Sex determination should be made by experienced observers and preferably through internal examination. The most productive direction for interpretation of validated ratios appears to be in terms of population density, hunting pressure, and the timing of harvest.

Factors Affecting Annual Deer Harvest In Arkansas, Richard A. Kluender, T. Bentley Wigley Jr., Michael E. Cartwright

Journal of the Arkansas Academy of Science

An understanding of general forces affecting annual harvest is essential to the management of white-tailed deer (Odocoileus virginianus). A predictive model based on such factors would be valuable to managers. The relationship between 27 different variables and annual, legal deer harvest in Arkansas was evaluated for 1957-1986. Variables most affecting harvest were soybean acreage, hay acreage, number of days in the deer season, rain during the deer season, and total state timber production, total state pulpwood production, and deer harvest 2 years prior. Because significant autocorrelation and heteroscedasticity were present in the variables, log-linear, first differencing and non-linear quasi-Newton regression …

Forest Habitat Use By White-Tailed Deer In The Arkansas Coastal Plain, T. B. Wigley Jr., M. E. Garner

Journal of the Arkansas Academy of Science

Forest habitat use by five radio-equipped white-tailed deer (Odocoileus virginianus) was monitored in the Arkansas Coastal Plain during 1982-84. The deer were located 821 times. Use of forest types was compared to expected use as calculated from availability. The study area was also divided into 491 two-hectare cells for which timber characteristics and number of deer locations were determined. Pine sawtimber was the most heavily used forest type in all seasons and was used more often than expected during spring. Also used more than expected were brushy areas (clearcut but not site prepared) during spring, summer and fall and openings …

Wolf Distribution And Road Density In Minnesota, L. David Mech, Steven H. Fritts, Glenn L. Radde, William J. Paul

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Distribution of the wolf (Canis lupus) in parts of Wisconsin (Thiel 1985) and Michigan and Ontario (Jensen et al. 1986) has been related to the density of roads passable by 2-wheel-drive vehicles. Wolves in those regions generally do not occur where road densities exceed 0.58 km/km², whereas similar areas nearby with fewer roads do contain wolves.

In a small segment of the wolf range in Minnesota, wolves did not have territories where roads exceeded a density of 0.73 km/km² (T. K. Fuller, Minnesota Department of Natural Resources, unpublished data). In another small area of Minnesota …

Can We Guarantee The Safety Of Genetically Engineered Organisms In The Environment?, Kathleen H. Keeler, Frances E. Sharples

School of Biological Sciences: Faculty Publications

Can we guarantee the safety of genetically engineered organisms in the environment? To anticipate my remarks, the answer to the title question is “No, we cannot guarantee the safety of genetically engineered organisms released into the environment.” Indeed, it is a tenet of the scientific method that nothing can be proved, only disproved. Thus, we can never show that a release will be safe. We could only show that it would be unsafe, if that were the case. However, if the question is posed differently, for example, can we safely release genetically engineered organisms into the environment?, the answer is …

Diet Choices Of Blue Jays (Cyanocitta Cristata) As A Function Of Time Spent Foraging, Sonja I. Yoerg, Alan C. Kamil

Papers in Behavior in Biological Sciences

Optimal diet theory predicts choices among prey types. With sequential prey encounters, less profitable prey types may be rejected immediately because rejecting the prey item at hand increases the probability of encountering more profitable types. However, Lucas (1985) argued that at the end of a foraging bout, all encountered prey types should be accepted because the opportunity to encounter more profitable types is limited. We tested Lucas’s prediction in a simulation, allowing blue jays to hunt for two moth types differing in profitability. During the last min of both 10- and 20-min foraging bouts, the less profitable type was attacked …
