1998 Southeast Nebraska Tallgrass Praire Inventory: Johnson, Gage, And Jefferson Counties, Final Report, Robert F. Steinauer Jan 1998

1998 Southeast Nebraska Tallgrass Praire Inventory: Johnson, Gage, And Jefferson Counties, Final Report, Robert F. Steinauer

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

This report is prepared as a requirement of the 1998 Southeast Nebraska Prairie Survey contract between the Platte/Rainwater Basin Project Office of the Nature Conservancy and Robert F. Steinauer. The original contract called for the examination of Johnson County south of Highway 136, and Gage County east of Beatrice. Due to the scarcity of prairies in these areas, the survey region was expanded to include northern Johnson County, and southern Jefferson County.

Prairies in these areas were identified using infrared and black and white photos, driving on county and within grassland roads, and conversations with landowners. Heritage Program “Site Survey …

1997 Inventory For Spiranthes Diluvialis Sheviak In Western Nebraska: A Final Report, Volume Ii, Terri Hildebrand

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

This study resulted from an agreement between Nebraska Game and Parks Commission (NGPC) and the United States Fish and Wildlife Service (USFW). After the 1996 discovery of Spiranthes diluvialis, in western Nebraska, NGPC was seeking to determine the extent of the Nebraska population. Information on the wet meadow community of orchid occurrence in Nebraska and eastern Wyoming was needed. This report includes descriptions of communities inventoried, Spiranthes diluvialis populations, and additional species monitored by Nebraska and Wyoming Natural Heritage programs.

Between May and September 1997, potential Spiranthes diluvialis habitat was inventoried for occurrences of the orchid. For all sites …

Declines In Benthic Macroinvertebrate Populations In Southern Lake Michigan, 1980–1993, Thomas F. Nalepa, David J. Hartson, David L. Fanslow, Gregory A. Lang, Stephen J. Lozano

United States Department of Commerce: Staff Publications

Densities of the major benthic macroinvertebrate groups declined dramatically at sites shallower than 50 m in southern Lake Michigan between 1980 and 1993. Declines in Diporeia, Oligochaeta, and Sphaeriidae ranged from 40 to 75% at these depths. Total densities declined from 16 800·m–2 in 1980–1981 to 4,800·m–2 in 1992–1993 at sites in the 16–30 m depth interval and from 21,300 to 11,300·m–2 at sites in the 31–50 m depth interval. Changes at sites deeper than 50 m were minimal; only sphaeriids declined to any extent. Declines in oligochaetes and sphaeriids occurred uniformly throughout the nearshore region …

Metazoan Parasites And Other Symbionts Of Cetaceans In The Caribbean, Antonio A. Mignucci-Giannoni, Eric P. Hoberg, Doug Siegel-Causey, Ernest H. Williams Jr.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The parasite fauna in cetaceans from Puerto Rico, the Virgin Islands, and the larger Caribbean region is poorly known. We provide the first records for parasite biodiversity among a diverse assemblage of cetaceans from the Caribbean Sea. Internal and external parasites and commensals were collected from stranded whales and dolphins salvaged in Puerto Rico, the United States and British Virgin Islands, Jamaica, and Venezuela between 1989 and 1997. A total of 47 individuals of 16 species of whales and dolphins (15 odontocetes and one mysticete) were examined. Overall, parasites and commensals were found in 34 (72.3%) animals, representing 13 species …

Terrestrial Natural Communities Of Nebraska - Version I, Gerry Steinauer, Steven B. Rolfsmeier

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

The Nebraska Natural Heritage Program has been collecting information and data including published literature, field observations and vegetation plot data over the last 10 years of development of Nebraska’s natural community classification. The classification contains 27 wetland and 36 upland communities including forest, woodland, shrubland, herbaceous, and sparsely vegetated (e.g. rock outcrop) types. The community types were distinguished primarily on plant species composition and to a lesser extent on soils, hydrology and geographic location. The classification contains descriptions of each community type that include dominant species, soils, range, and other ecological information. The classification is designed to be flexible enough …

Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins Sep 1997

Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins

School of Natural Resources: Faculty Publications

We surveyed the mollusks of the Niobrara River in Nebraska from 1992–1996. We found two species of unionid clams and ten species of snails that either must live in water or near water. Both clams and snails are poorly sampled in the state, however we attribute the low number of species of unionid clams in the Niobrara to its cold, fast flow and rocky bottom. In contrast, the Platte River is slower moving with a muddy bottom and has at least 11 species of unionid clams. Each species has been mapped with latitude/longitude coordinates. Specimens have been curated and are …

Endangered And Threatened Wildlife And Plants; Final Rule To Designate The Whooping Cranes Of The Rocky Mountains As Experimental Nonessential And To Remove Whooping Crane Critical Habitat Designations From Four Locations Jul 1997

Endangered And Threatened Wildlife And Plants; Final Rule To Designate The Whooping Cranes Of The Rocky Mountains As Experimental Nonessential And To Remove Whooping Crane Critical Habitat Designations From Four Locations

Endangered Species Bulletin

The U.S. Fish and Wildlife Service determines that it will designate the whooping crane (Grus americana) population of the Rocky Mountains as an experimental nonessential population and will remove whooping crane critical habitat designations from four National Wildlife Refuges; Bosque del Apache in New Mexico, Monte Vista and Alamosa in Colorado, and Grays Lake in Idaho. The private lands involved are holdings inside refuge boundaries and a 1-mile buffer around Grays Lake National Wildlife Refuge. The Service will use this population, and captive-reared sandhill cranes and whooping cranes, in experiments to evaluate methods for introducing whooping cranes into …

The Use Of Plot Surveys For The Study Of Ethnobotanical Knowledge: A Brunei Dusun Example, Jay H. Bernstein, Roy Ellen, Bantong Bin Antaran Jul 1997

The Use Of Plot Surveys For The Study Of Ethnobotanical Knowledge: A Brunei Dusun Example, Jay H. Bernstein, Roy Ellen, Bantong Bin Antaran

Publications and Research

This paper describes a technique for using plot surveys to measure individual informants' ethnobotanical knowledge of forests, as applied to the Dusun community of Merimbun in Brunei. Two knowledgeable but non-literate Dusun informants enumerated marked plots of both recent and old secondary growth mixed dipterocarp forest near the village. They were able to provide names (other than life-forms or the most general basic and intermediate categories) for 86-97% of species growing in the plots. Between 152 and 170 plant names were elicited by the surveys. In all cases, about 88% of the names were at the basic naming level and …

Habitat Use By Migrant Whooping Cranes In Saskatchewan, Brian W. Johns, Eric J. Woodsworth, Ed A. Driver Jan 1997

Habitat Use By Migrant Whooping Cranes In Saskatchewan, Brian W. Johns, Eric J. Woodsworth, Ed A. Driver

Proceedings of the North American Crane Workshop

We investigated habitat use by migrating whooping cranes (Grus americana) in Saskatchewan between 1986 and 1990. At foraging and roosting sites and a sample of randomly selected sites we measured various habitat parameters. Palustrine and lacustrine wetlands were the most frequently used wetlands. Temporary and seasonal wetlands were the primary roost habitat during spring migration, and semi-permanent and permanent wetlands were frequently used during the fall. Cranes were attracted to areas of higher than average wetland density. Land use within 2 km of roost sites was intensively modified by man. Cereal crops were the most used feeding areas. …


Availability Of Stopover Habitat For Migrant Whooping Cranes In Nebraska, Dale W. Stahlecker Jan 1997

Availability Of Stopover Habitat For Migrant Whooping Cranes In Nebraska, Dale W. Stahlecker

Proceedings of the North American Crane Workshop

Four stratified random samples of 512 National Wetland Inventory (NWI) maps within the central Nebraska portion of the Wood Buffalo-Aransas whooping crane (Grus americana) migration corridor were used to evaluate the availability of wetland roost sites. Wetlands were eliminated as potential roosts if visibility was obscured by vegetation or slope, if certain human activities occurred within 100-800 ro, or if water < 30 em deep was not available. Seasonal emergent wetlands, available as roosts primarily in spring, dominated all samples, particularly in the nortb. Sixty-five percent of all wetlands >0.04 ha passed map review and 52 % passed when ground-truthed. NWI map review was a good predictor of both suitability (63 % correct) and unsuitability (73 % correct). More than one-half of all open and emergent …
