Use Of Drc 1339 To Control Crows In Three Roosts In Kentucky And Arkansas, Frank L. Boyd, Douglas I. Hall Oct 1987

Use Of Drc 1339 To Control Crows In Three Roosts In Kentucky And Arkansas, Frank L. Boyd, Douglas I. Hall

Third Eastern Wildlife Damage Control Conference (1987)

Field tests utilizing DRC 1339 (3- chloro-4-methylbenzamine hydrochloride) 98% concentrate on whole kernel corn for crow (Corvus brachyrhynchos) control were conducted in January and February 1981 in Lexington and Louisville, Kentucky, and in 1982 in Ashdown, Arkansas. Treated bait was placed in staging areas near the roosts after pre-baiting indicated good acceptance at the sites. The rate of acceptance varied with bait placement. Best results were obtained when bait was placed on bare ground at habitually used staging areas close to the roost site. Population reductions of up to 25% were obtained with limited baiting. DRC 1339 appears …

Management Of Prairie Dog Populations In Wind Cave National Park, Richard W. Klukas Apr 1987

Management Of Prairie Dog Populations In Wind Cave National Park, Richard W. Klukas

Great Plains Wildlife Damage Control Workshop Proceedings

Since the late 1920's there have been periodic control programs on black-tailed prairie dogs in Wind Cave National Park. The most recent control effort, which began in 1982, resulted in the reduction of total dogtown acreage from 2,000 to 750 acres. Recent studies carried out within the park have provided managers with more soundly based justification for carrying out control programs. The same information also points to the importance of maintaining prairie dog populations at or above certain minimum levels and the need for integrating this control program with several of the other resource management programs being carried out in …


Small Mammals: Pests Or Vital Components Of The Ecosystem, Carolyn Hull Sieg Apr 1987

Small Mammals: Pests Or Vital Components Of The Ecosystem, Carolyn Hull Sieg

Great Plains Wildlife Damage Control Workshop Proceedings

Small mammals regarded as "pests" should not be viewed separately from other components in the ecosystem. Small mammals have significant influences on vegetation and soils, exert predatory pressure on other animals, and provide food for predators. Future management efforts should include consideration of these diverse influences.


Diving Birds Of North America: Species Accounts — Grebes (Podicipedidae), Paul A. Johnsgard Apr 1987

Diving Birds Of North America: Species Accounts — Grebes (Podicipedidae), Paul A. Johnsgard

Diving Birds of North America by Paul A. Johnsgard

Grebes are small to medium-sized diving birds having bills that vary from short and rather blunt tipped to long and acutely pointed, with bare lores and head feathers not extending to the linear or oval nostrils. There are 11 functional primaries and 17–22 secondaries, the inner secondaries longer than the primaries. Molting of the primaries is simultaneous; the wings are not used for underwater propulsion, which is provided by the feet. The rectrices are soft, rudimentary, and hidden. The body feathers are small, water-resistant, and shiny. Aftershafts and adult down feathers are present. The legs are set extremely far back …


Biological Features Of Saline Wetlands In Lancaster County, Nebraska, James E. Ducey Jan 1987

Biological Features Of Saline Wetlands In Lancaster County, Nebraska, James E. Ducey

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The natural history of saline wetland areas near Lincoln, Lancaster County, was evaluated. Most remaining salt marshes occur on saline soils along Little Salt Creek. Numerous plant species of saline soils occur that are limited to this part of the State. The avifauna is diverse, with 67 species recorded during the breeding season, 47 of them breeding. Because wetlands are limited in distribution in Nebraska, key biological elements, potential threats to the areas, and management considerations are discussed.


Comparison Of Plant Species Composition Of Mormon Island Crane Meadows And Lillian Annette Rowe Sanctuary In Central Nebraska, Harold G. Nagel, Ole A. Kolstad Jan 1987

Comparison Of Plant Species Composition Of Mormon Island Crane Meadows And Lillian Annette Rowe Sanctuary In Central Nebraska, Harold G. Nagel, Ole A. Kolstad

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Mormon Island Crane Meadows (MICM) and Lillian Annette Rowe Sanctuary (LARS) are both western extensions of true prairie vegetation and are sandhill crane sanctuaries. Both are located on the Platte River, 35 km (22 mi) apart, in Central Nebraska. MICM is about 827 ha (2100 ac) and is owned by the Platte River Whooping Crane Habitat Maintenance Trust. LARS is about 324 ha (800 ac) and is owned by the National Audubon Society.

Plants were collected and vegetation was sampled with square meter cover quadrats (N=314 on MICM and 204 on LARS) in 1980 and 1981. Both areas are on …

Bioconcentration Of Heavy Metals (Cu, Cr, Pb, And Zn) In The Missouri River Near Sioux City, Iowa, Robert Conklin, Suzie Galles, Edward Shane, Rod Tondreau Jan 1987

Bioconcentration Of Heavy Metals (Cu, Cr, Pb, And Zn) In The Missouri River Near Sioux City, Iowa, Robert Conklin, Suzie Galles, Edward Shane, Rod Tondreau

US Army Corps of Engineers

The concentrations of the heavy metals- copper, chromium, lead, zinc- in the biota of the Missouri River were measured at a control site upstream of Sioux City and at a site downstream of the city. Bioconcentration factors for each of the metals were calculated for fish, periphyton, and invertebrates, and the concentrations of metals in the river sediments were measured.

Concentrations of the same metals were measured in the sediment, water, periphyton, invertebrates, zooplankton, and fish of Snyder's Bend Lake. Bioconcentration factors were calculated for each of the biological communities and were found to be very similar to those found …


The Characteristics And Phytogeographic Affinities Of The Flora Of Nine-Mile Prairie, A Western Tall-Grass Prairie In Nebraska, Robert B. Kaul, Steven B. Rolfsmeier Jan 1987

The Characteristics And Phytogeographic Affinities Of The Flora Of Nine-Mile Prairie, A Western Tall-Grass Prairie In Nebraska, Robert B. Kaul, Steven B. Rolfsmeier

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Three hundred ninety-two species, subspecies, and varieties have been recorded at Nine-Mile Prairie, a relict tall-grass prairie that has been reduced from 323 to 97 ha in the past 50 years. There are 218 native and 17 introduced herbaceous perennial species, and 73 native and 24 introduced annuals. Analogous numbers for biennials are 15 and 11, for shrubs are 14 and one, for trees are ten and three, and for woody vines are six and none. One hundred twenty-one native species are of central and eastern North American phytogeographic affinity, and 109 are of transcontinental affinity. Seventy-nine of the Prairie's …
