Some Helminth Parasites Of Dunlin (Calidris Alpina) And Western Willet (Catoptrophorus Semipalmatus Inornatus) From California, Hilda Lei Ching Jan 1990

Some Helminth Parasites Of Dunlin (Calidris Alpina) And Western Willet (Catoptrophorus Semipalmatus Inornatus) From California, Hilda Lei Ching

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Dunlins and western willets were collected on their winter feeding grounds at Bodega Bay and Bolinas Lagoon, California, during 1986. Six digeneans, eight cestodes, two acanthocephalans, and a new nematode were found in dunlins. Seven digeneans, two cestodes, one acanthocephalan, and the new nematode were found in western willets; four helminths including the new roundworm were common to dunlins. Thominx cecumitis sp. n. differs from other capillarid nematodes with a spinous spicule-sheath in having a short, globular vulvar appendage, peanut-shapcd eggs, a cuticular ball at the posterior tip of the body, narrow lateral alae, and a cuticular genital bursa.

Helminth Parasitism In Martens (Martes Americana) And Ermines (Mustela Erminea) From Washington, With Comments On The Distribution Of Trichinella Spiralis, Eric P. Hoberg, Keith B. Aubry, J. David Brittell

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminths are reported for the first time from ermines (Mustela erminea) and martens (Martes americana) in Washington, USA. Among 22 adult ermines, 41% were infected by one or more of five species (Taenia mustelae, Alaria mustelae, Molineus patens, M. mustelae, and Trichinella spiralis). Among 78 adult martens from three geographic localities, the prevalence was 83%. Nine species were identified (Mesocestoides sp., T. mustelae and T. martis americana, Euryhelmis squamula, M. patens, Baylisascaris devosi, Physaloptera sp., Soboliphyme baturini, and T. spiralis). Trichinella spiralis …


Hawks, Eagles, And Falcons Of North America: Biology And Natural History, Paul A. Johnsgard Jan 1990

Hawks, Eagles, And Falcons Of North America: Biology And Natural History, Paul A. Johnsgard

Paul Johnsgard Collection

I have tried to present an adequate if far from exhaustive survey of the general biology, ecology, and behavior of all the included species, written so as to be understandable to the interested layman as well as useful to the biologist who might be looking for relevant literature citations or trying to deal with a specific question without resorting to extensive library searches. The larger number of species of North American hawklike birds (31, compared to 19 owl species) has required that I keep the individual species accounts substantially shorter. I have excluded the New World vultures from consideration, primarily …

Species Richness Gradients Of Oak Forest Plants Along The Missouri River In Nebraska And Iowa, Steven B. Rolfsmeier Dec 1989

Species Richness Gradients Of Oak Forest Plants Along The Missouri River In Nebraska And Iowa, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The upland deciduous forests of the Missouri River valley contain many plants typical of forests to the east of this area, which are assumed to have migrated northward and westward along the river in postglacial times. Previous workers have reported a gradient of decreasing species richness upstream among woody species, which is suggested to be the result of climatic gradients and differential dispersal capabilities of the immigrant species. Floristic work on all vascular species in eight woodland sites along the Nebraska-Iowa border quantifies the presence of similar gradients for herbaceous species, but of differing degrees. These studies also reveal the …

Endangered And Threatened Wildlife And Plants; Proposed Rule To Determine The Pallid Sturgeon To Be An Endangered Species Aug 1989

Endangered And Threatened Wildlife And Plants; Proposed Rule To Determine The Pallid Sturgeon To Be An Endangered Species

Endangered Species Bulletin

The Service proposes to determine the pallid sturgeon (Scaphirhynchus albus) to be an endangered species under the authority of the Endangered Species Act (Act) of 1973, as amended. The pallid sturgeon is a large fish known only to occur in the Missouri River, the Mississippi River downstream of the Missouri River, and the lower Yellowstone River. The species is threatened through habitat modification and apparent lack of reproduction. Numbers of fish reported have declined dramatically in the last two decades. Past commercial utilization likely exceeded biological recruitment. Pollution may be a problem over much of its range, and …


Winchester Sub-Catchment Management Plan, Vivian T. Read Aug 1989

Winchester Sub-Catchment Management Plan, Vivian T. Read

Soil conservation survey collection

The 590 Ha Winchester sub-catchment has no apparent external drainage. Groundwater levels are rising causing site specific problems. Wind erosion has severely affected some areas.The objective of this report is to provide a sub-catchment management plan that is based on sustainable agricultural systems and a hydrological equilibrium. The recommendations aim to meet this objective in the long term. Recommendations to achieve short term results are considered separately. These measures have relatively high installation and maintenance costs. They should be considered as interim management methods until the recommendations for long-term control become effective (perhaps 3 - 5 years after implementation).

Endangered Species Bulletin

The U.S. Fish and Wildlife Service determines the American burying beetle (Nicrophorus americanus) to be an endangered species under the authority of the Endangered Species Act of 1973 (Act), as amended, Once widely distributed throughout eastern North America, thi8 species has disappeared from most of its former range. Two known populations currently exist, one In eastern Oklahoma and the other on an Island off the coast of New England. Despite extensive efforts to locate additional populations, only two specimens have been found elsewhere in more than ten years. The cause of the species’ decline is unknown. Critical habitat …

The Nebraska Natural Heritage Program: Two Year Progress Report, Mary Clausen, Mike Fritz, Gerry Steinauer

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Since European settlement, human activities have totally eliminated the natural vegetation from approximately 50 percent of Nebraska’s landscape, and of that remaining most has been heavily impacted. As a result, numerous plants and animals have been extirpated from the state and many others are threatened.

The destruction of Nebraska’s natural diversity resulted in both public and private conservation groups recognizing the need for a centralized and accessible biological database for the state’s rare species and natural community types. Toward this end, the Nebraska Natural Heritage Program (NENHP) was established in August, 1987 through a cooperative effort between The Nature Conservancy …

Wolf Population Survival In An Area Of High Road Density, L. David Mech Apr 1989

Wolf Population Survival In An Area Of High Road Density, L. David Mech

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

Wolf mortality in a high-road-density area of Minnesota exceeds that in an adjacent wilderness, and is primarily human-caused. The wolf population there is maintained primarily by ingress from the adjacent wilderness areas. A road density of 0.58 km/km2 can be exceeded and the area still support wolves if it is adjacent to extensive roadless areas.

Land Capability And Land Use In The Leeuwin-Naturaliste Region, Peter John Tille, Neil Lantzke Jan 1989

Land Capability And Land Use In The Leeuwin-Naturaliste Region, Peter John Tille, Neil Lantzke

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

The Leeuwin-Naturaliste region is one of Western Australia's most beautiful areas. Located in the far south-west corner of the State, it is a popular scenis and tourist spot, as well as supporting grazing, horticultureal and viticultural enterprises.

Outside of perth the region is the most popular tourist destination in the state. It is also responsible for about a quarter of the State's milk production, and 15 percent of the state's potato production and a quarter of the State's wine grapes.

Many new agricultural enterprises have opened up in the past 15 years, and the population has increased by almost 40 …


Leaf Optical And Indirect Lai Measurements In Wheat And Alfalfa At Maciv: Agmet Progress Report 89-4, E. A. Walter-Shea, B. L. Blad Jan 1989

Leaf Optical And Indirect Lai Measurements In Wheat And Alfalfa At Maciv: Agmet Progress Report 89-4, E. A. Walter-Shea, B. L. Blad

School of Natural Resources: Documents and Reviews

Interpretation of remotely sensed vegetative surfaces requires an understanding of the interaction of radiation with the various components of vegetation. Leaves are the most important component. Thus it is important to know the optical properties of individual leaves as well as the amount and distribution of leaves making up the vegetative cover. The objectives of our study were 1) to characterize the reflectance from and transmittance through adaxial and abaxial surfaces of individual wheat and alfalfa leaves and 2) to compare the traditional, time-consuming, destructive method of estimating LAI (direct method) to a relatively quick, indirect estimate of LAI in …
