Noch immer gelten zahlreiche Arten der zentralasiatischen Säugetierfauna als kaum bis wenig erforscht. Fundierte ökologische Untersuchungen an den mongolischen Springmausarten liegen bisher nicht vor. Sowohl Salpingotus crassicauda als auch Cardiocranius paradoxus sind durch ihre begrenzten Vorkommen in Kasachstan bzw. Tuva sogar im Rotbuch der Sowjetunion (1985, Literatur S. dort) verankert.

Reports

This initial phase of the project involves assessing the present state of knowledge of sediments in Tampa Bay and the identification of data gaps, or areas where more detailed information is required to achieve project objectives. The literature search produced 273 data sources that from their abstracts in the data base are applicable to the project (Appendix I). Data sources were reviewed by experts in the fields of sedimentology, nutrient chemistry, organic geochemistry, trace metal and radionuclide geochemistry, and benthic biology who then contributed the following summary sections.

13.2.4. Avian Botulism: Geographic Expansion Of A Historic Disease, Louis N. Locke, Milton N. Friend

Waterfowl Management Handbook

Avian botulism is a paralytic, often fatal disease of birds resulting from ingestion of toxin produced by the bacterium Clostridium botulinum. Waterfowl die-offs from the botulism are usually caused by type C toxin; sporadic die-offs among fish-eating birds, such as common loons (Gavia immer) and gulls, have been caused by type E toxin.

Not enough is known about avian botulism to precisely identify the factors leading to an outbreak. When an outbreak does occur, it is usually perpetuated by a well-understood bird-maggot cycle (Figure 1).

13.4.11. Control Of Purple Loosestrife, Daniel Q. Thompson

Waterfowl Management Handbook

Purple loosestrife is an herbaceous perennial weed that is native to Eurasia and probably arrived in eastern North America with early maritime traffic. The spread of this alien by 1900 (Fig. 1) was closely associated with canal and waterway traffic. By 1985 (Fig. 2), this aggressive weed had spread into all of the contiguous States north of the 35th parallel except Montana; similarly, all of the southern provinces of Canada had been invaded. In the last 20 years, loosestrife has become well established in reclamation projects and riparian wetlands in the West and Northwest. It has also invaded estuarine marshes …

Differentiation Of Mule Deer And White-Tailed Deer, David Oates

Other Publications in Wildlife Management

The mule deer was so named because of the appearance of its ears. Compared to the whitetail's, the mule deer's ears are noticeably oversized, measuring fully one-fourth larger. The whitetail is also well named, for its most distinctive feature is the large tail or "flag." The upper surface of the underside is pure white and is often exposed when the deer is fleeing. Instead of a "white flag," the mule deer's tail can be more likened to a black-tipped rope. Antlers, too, serve to differentiate the species. In the whitetail, the points on each antler arise from a single main …

Toxicity And Environmental Health Hazards Of Petroleum Products In Wells Used For Drinking Water In The Intermountain West, Robert D.R. Parker, Raghubir P. Sharma, R. Ryan Dupont, Gin-Chang Hsieh

Reports

Introduction: Groundwater is aprimary source of drinking water for about 50 percent of the population in the U.S. This source of drinking water has been generally regarded as safe from contamination. Several papers indicate that numerous underground storage tanks containing petroleum products may be leaking and contaminating public water supply wells across the U.S. (Matis, 1971; Ferguson, 1979; Woodhull, 1981; Burmaster and Harris, 1982; Lehman, 1984; Dowd, 1984; OTA, 1984). A study conducted by the Utah Cureau of Solid and Hazardous Wastes in 1985 concluded that there are at least 2,314 underground steel tanks, most of which are used to …

Soil Phase Photodegradation Of Toxic Organics At Contaminated Disposal Sites For Soil Renovation And Groundwater Quality Protection, W. M. Moore, R. Ryan Dupont, J. E. Mclean

Reports

Accurate assessment of the potential for contaminated soil remediation requires detailed knowledge of the fate of waste constituents within the soil environment. For many non-biodegradable organics compounds, photochemical degradation may provide a potential pathway for the removal of such compounds from soil surfaces. A study was conducted to evaluate the rate of photodegradation of ten hazardous organic compounds from three soils, silica gel, and four soil minerals (kaolinite, montmorillonite, illite, and calcite) under conditions of controlled irradiation. In addition, the effect of siz amendment treatments (methylene blue, riboflavin, hydrogen peroxide, diethylamine, peat moss, and silica gel) on the rates of …

Evaluation Of Algrow As A Binder In Hydromulch And Preliminary Determination Of The Influence Of Algrow On Germination And Seedling Growth, C. Earl Israelsen, Gilberto Urroz, Ronald V. Canfield

Reports

Introduction: The application of mulch during or immediately following seeding provides the minimum following advantages: energy dissipation of falling raindrops which decreases or eliminates erosion, prevention of surface-soil crusting, decreased water loss, and surface temperature modification. To better hold mulch in place, chemical binders are addd to it during munufacture or just before it is applied to the soil. Sometimes a binder is applied as an oversptray after the mulch is in place. (This overspray is generally referred to as a tackifier.) Algea Produkter A/S, Drammen, Norway, produces a product called ALGROW which may habe utility as a mulch binder …

Incidence Of Lead Shot In The Rainwater Basins Of South Central Nebraska, David W. Oates

Nebraska Game and Parks Commission: Staff Research Publications

Substrate samples were taken from eight marshes in southern Nebraska during the summers of 1985 and 1986 when the marshes were relatively dry. Each sample was 12 inches square by 2 inches deep. The number of samples per marsh ranged from 66 to 112, with transect lengths ranging from 71 to 201 m. Based on a 97.5% recovery rate, these marshes contained an average of 47,217 lead and 5849 steel shot per hectare. Ranges were from 20,690 to 90,286 pellets per hectare for lead and 0 to 14,044 pellets per hectare for steel.

Protected Species – Research Permits And The Value Of Basic Research, Katherine Ralls, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

The complexities involved in obtaining permits for field research using protected species continue to increase. In October 1988, Congress amended the Marine Mammal Protection Act (MMPA) to increase the documentation required to obtain a scientific research permit (PL 100-711). Applicants for scientific research permits must now submit “information indicating that the taking is required to further a bona fide scientific purpose and does not involve unnecessary duplication of research.”

Human Impacts To Minnesota Wetlands, Carol A. Johnston

Journal of the Minnesota Academy of Science

ABSTRACT-Minnesota's 3.6 million ha of wetlands have been impacted by a variety of human activities, including agricultural drainage, urbanization, water control, and nonpoint source pollution. More than half of Minnesota's wetlands have been destroyed since the first European settlers arrived, an average loss of about 35,600 ha/yr. Drainage for agriculture is the major cause of wetland loss in Minnesota, particularly in southern Minnesota and the Red River Valley. In addition to impacting wetlands directly, wetland drainage affects downstream areas by increasing flood flows, and releasing sediment and nutrients. Urban development and highway construction affect a smaller proportion of Minnesota's wetlands, …

The Effect On Farm Profit Of Conserving Stubble To Prevent Wind Erosion, A D. Bathgate

Journal of the Department of Agriculture, Western Australia, Series 4

Over-grazing of stubbles is a major cause of winf erosion on WesternAustralian farms. Stubble contributes to the 'roughness' of the paddock; as the roughness is reduced, the risk of winf erosion is increased.

The risk of lupinosis in sheep has previously reduced the likelihood of lupin stubble being over grazed, but the development of Gungurru, a phomopsis-resistent variety of lupin, has increased the potential for over-grazing and hence the probability of wind erosion.

This article describes the economic benefit (or cost) of conserving stubble at the conservation standards.
