Vertebrate Pest Management And Changing Times, Donald A. Spencer

Vertebrate Pest Conference Proceedings: 10th (1982)

Everywhere one turns today there are problems. The gristmills of doom and disaster are experiencing a heyday marketing this situation as one of crisis and extinction. An advantage of being an oldster in this society is that one has the perspective to recognize that these are only problems, some simple, some complex, presenting a challenge for solution to all who will lay aside their emotions and face reality. In presenting this overview of vertebrate pest management programs, I find I must dwell too frequently on "problems." This should not be interpreted as a pessimistic outlook. Sound data with professional guidance …

Teaching Vertebrate Pest Control: A Challenge To Wildlife Professionals, Robert M. Timm

School of Natural Resources: Faculty Publications

Vertebrate pest control deals with wild animals that create health hazards, damage resources, or become a general nuisance. Some people prefer the terms "wildlife damage control" or "animal damage control" because they focus on controlling damage rather than controlling animals. This is an important principle. Vertebrate animals that cause damage often have many positive values. In dealing with these situations our objective should always be to reduce or prevent damage; this does not necessarily require the killing of animals. I use the term "vertebrate pest control" because I believe it is less ambiguous than "damage control." When I call an …

A Preliminary Assessment Of Nutrient Loading Into Narragansett Bay Due To Urban Runoff, Lynne Carter Hanson

Marine Affairs Theses and Major Papers

This study is a component of a more comprehensive investigation at the Marine Ecosystems Research Laboratory, (MERL), University of Rhode Island, that was undertaken in order to assess the potential for eutrophication in both its meanings as a natural and man-induced process occurring in the upper portions of Narragansett Bay and its watershed. This assessment required identification and quantification of the various inputs in order to establish the annual loading and eventual effects of the four important nutrients; ammonia, nitrate-nitrite, silicate and phosphate.

The Exploitation Of The Antarctic Oil And Its Environmental And Legal Implications, Renzo Follegati

Marine Affairs Theses and Major Papers

The focus of the paper is the feasible exploitation of the Antarctic offshore oil and the environmental consequences that this fact could have to the whole ecosystem of the Southern Ocean and for other ecosystems of neighboring regions, e.g. the South East Pacific basin. The legal implications that have to do with the exploitation of the Antarctic oil and the regulations that could be applied to preserve the environment are examined.

Interactions Of Northern Fur Seals And Commercial Fisheries, Charles W. Fowler

United States Department of Commerce: Staff Publications

Under international agreement, the northern fur seal (Callorhinus ursinus) is managed with the objective of obtaining a maximum sustainable yield. Currently the harvest is restricted to subadult males; however, between 1956 and 1968 the fur seal population of the Pribilof Islands was subjected to a harvest of females. This harvest was justified, in part, as an attempt to stimulate the production of greater quantities of harvestable animals (Chapman 1981). A reduction in the population occurred during this period as can be seen in Figure 1. As described in York and Hartley (1981), the female harvest itself provides an …

Primary Production In Tampa Bay, Florida: A Review, J.O. R. Johansson

Reports

Primary production data for Tampa Bay is very limited. The phytoplankton component has received the greatest study effort; however, even knowledge of this group is limited and biased by the lack of area-wide and long-term studies, and the use of questionable methodologies. This review will summarize historical primary production data; discuss methodologies and their shortcomings; outline future research needs for understanding the carbon cycle of the Tampa Bay system; and discuss the carbon cycle in relation to trophic dynamics.

Effect Of Herbicides On Performance Of Aerobic Dairy Lagoons, John D. Bottom, Joseph L. Taraba

Biosystems and Agricultural Engineering Faculty Publications

The herbicides glyphosate, bromacil, and dalapon were assessed for their affect on the oxygen uptake of microorganisms from an aerated dairy lagoon at 20 °C. The maximum recommended addition of herbicide active ingerdient to a lagoon is: glyphosate (isopropyl amino salt)—0.42 mg/L; bromacil—3.70 mg/L; and dalapon (85.8 percent Na salt and 14.2 percent Mg salt)—1.95 mg/L. In addition, microorganism isolates from the aerobic dairy lagoon were incubated under aerobic and anerobic conditions at room temperature to assess the effects of the herbicides. Under aerobic incubation, it was found that neither herbicide type nor herbicide concentration affected isolate growth. Under anaerobic …

Management Of Roosevelt Elk Habitat And Harvest, E. E. Starkey, D. S. Decalesta, G. W. Witmer

United States National Park Service: Publications

Historically, Roosevelt elk (Cervus elaphus roosevelti) were distributed from northern California to southern British Columbia in the coastal Pacific Northwest. During the Pleistocene, the subspecies was isolated reproductively from the Rocky Mountain elk (C. e. nelsoni) to the east by the Cascade Mountain Range and by glaciation (Guthrie 1966). Thus Roosevelt elk have adapted to relatively moist forest habitats with maritime climates, while Rocky Mountain elk evolved under the continental climate of the interior.
Unfortunately, less is known of Roosevelt elk biology than of the closely related Rocky Mountain elk east of the Cascades. This has …

Aquatic Plant Communities And Invertebrates In A Prairie Pothole During Duck Brood Rearing, Jeffrey W. Mccrady

Electronic Theses and Dissertations

More than 1,100 samples of aquatic plants and associated invertebrates were collected in a prairie wetland. Sampling was done weekly throughout the duck brood rearing season. Linear regression revealed a 4 to 100 ratio of animal to plant biomass (R²=0.488). Comparatively high degrees of association were found between Ceratophyllum demersum and Gastropoda and between Lemna minor and most zooplankton groups. Significant sources of variation in invertebrate biomass were plant communities, date, plants, and community by date interaction. Depth and communities were not significant.

Food Habits And Placental Scar Counts Of Bobcats In South Dakota, David Eric Nomsen

Electronic Theses and Dissertations

Bobcat (Lynx rufus) food habits and placental scar counts were investigated in western South Dakota during 1978-79 and 1979-80 trapping and hunting seasons. Food habits were recorded by frequency of occurrence and placental scar counts were used to determine litter size for South Dakota bobcats. Rabbits (Sylvilagus spp. and Lepus spp.), rats and mice (primarily Microtus spp. and Peromyscus spp.), and deer (Odocoileus spp.) were identified in 56, 32, and 7% of bobcat stomachs, respectively. Analysis showed that rabbits, rats and mice, and deer occurred in 58, 36, and 9% of bobcat intestines, respectively. Occurrences in rabbits decreased from 67% …

Electronic Theses and Dissertations

Radio telemetry and brood surveys were used to evaluate wood duck (Aix sponsa) brood habitat and movements along 40 km of the Big Sioux River in eastern South Dakota during 1979-81. Most of the oxbows and nearby wetlands in the study area contained water in 1979-80, but drought dried all but 2 of the 33 oxbows in 1981. Fourteen brood hens were radio monitored. In 1980, 4 hens utilized oxbows, 1 hen utilized the river, and 2 hens used other habitats for brood rearing. In 1981, 4 hens utilized oxbows, 2 hens utilized the river, and 1 hen utilized the …

Composition, Biomass, And Protein Content Of A Lemna Trisulca L., Invertebrate Community In A Prairie Wetland, Linda J. Meyers

Electronic Theses and Dissertations

Samples of star duckweed (Lemna trisulca L.) were collected from a South Dakota prairie wetland during the summer 1981. Amphipods and gastropods were the dominant macroinvertebrates found within samples of duckweed in terms of biomass and density. Cladocera were the dominant microinvertebrates found in association with star duckweed. Significant variability was found in the biomass and densities of specific invertebrates with respect to sampling dates. Crude protein values of star duckweed-invertebrate community samples ranged from 7.6 to 18.5% and were found to correlate significantly with protein levels of the duckweed. Crude protein values for star duckweed ranged from 7.1 to …

In Search Of A Diversity Ethic For Wildlife Managemen, Fred B. Samson, Fritz L. Knopf

United States Department of Agriculture Wildlife Services: Staff Publications

As the century nears its end and demand for food and competition for land escalate, a most important issue facing conservationists will be the preservation of a mosaic of habitats in which can be preserved a representative cross-section of native species. The need to resolve this issue is emphasized in the Global 2000 Report to the President (Council on Environmental Quality 1980) which predicts that, worldwide, 500,000 to 2 million species will become extinct by the year 2000 and that the rate will increase from one per day in 1980 to one per hour by century's end (Myers 1979). Although …

An Evaluation Of The Performance Of A Modified Overland Flow Wastewater Treatment System: Sloped Rock-Grass Filtration, Daria Wightman, Dennis B. George, John H. Zirschky, Daniel S. Filip, Judith Sims
