Farm Structure And Use Of The Conservation Reserve Program Of The 1985 Farm Bill, Joseph N. Kairumba, Gerald C. Wheelock Dec 1990

Farm Structure And Use Of The Conservation Reserve Program Of The 1985 Farm Bill, Joseph N. Kairumba, Gerald C. Wheelock

Journal of Rural Social Sciences

Within the conservation and production objectives that form the current Farm Bill, there are a range of options that encourage uniquely tailored farm plans for each farm and landowner (LO) situation. In this attempt to predict use of one option, the Conservation Reserve Program (CRP), three broad sets of farm structure variables were employed. These were farming scale, planning horizon, and farm specialization. A two-stage systematic sample of 437 farm parcels from county ASCS lists resulted in 187 land owner interviews for discriminant analysis. Participation in CRP was most discriminated by two farm size variables--crop acres and gross farm income. …


Spatial Pattern And Interference In Piñon-Juniper Woodlands Of Northwest Colorado, Charles W. Welden, William L. Slauson, Richard T. Ward Dec 1990

Spatial Pattern And Interference In Piñon-Juniper Woodlands Of Northwest Colorado, Charles W. Welden, William L. Slauson, Richard T. Ward

Great Basin Naturalist

The local spatial arrangement of the coniferous trees Pinus edulis and Juniperus osteosperma was mapped in two woodland stands and measured in two shrub-dominated stands in the semiarid Piceance Basin of northwest Colorado. In the woodlands, small trees were often clumped, while medium and large trees were either randomly or uniformly dispersed. Significant regressions were obtained between a tree's basal area or canopy area and the area of its Dirichlet domain (the region closer to it than to any other tree). Both findings from the woodland stands accord with results obtained by other workers in other vegetation. Like earlier workers, …


Eimeria Sp. (Apicomplexa: Eimeriidae) From Wyoming Ground Squirrels Spermophilus Elegans, And White-Tailed Prairie Dogs, Cynomys Leucurus, In Wyoming, Larry M. Shults, Robert S. Seville, Nancy L. Stanton, George E. Menkens Jr. Dec 1990

Eimeria Sp. (Apicomplexa: Eimeriidae) From Wyoming Ground Squirrels Spermophilus Elegans, And White-Tailed Prairie Dogs, Cynomys Leucurus, In Wyoming, Larry M. Shults, Robert S. Seville, Nancy L. Stanton, George E. Menkens Jr.

Great Basin Naturalist

Six species of the coccidian genus Eimeria (E. larimerensis [prevalence = 17%], E. bilamellata [12%] E. beecheyi [34%], E. morainensis [43%], E. callospermophili [21%], and E. spermophili [5%]) were recovered from Wyoming ground squirrels (Spermophilus elegans elegans) collected during 1983, 1984, 1985, and 1986. Infected ground squirrels were found to harbor from one to five species simultaneously. The 1007 hosts examined were collected from two different habitats: (1) a xeric desert shrub-steppe and (2) an irrigated alfalfa-brome field. All species of Eimeria occurred at each study site during all years, although the prevalence of each species varied …


Emergence, Attack Densities, And Host Relationships For The Douglas-Fir Beetle (Dendroctonus Pseudotsugae Hopkins) In Northern Colorado, E. D. Lessard, J. M. Schmid Dec 1990

Emergence, Attack Densities, And Host Relationships For The Douglas-Fir Beetle (Dendroctonus Pseudotsugae Hopkins) In Northern Colorado, E. D. Lessard, J. M. Schmid

Great Basin Naturalist

Douglas-fir beetle-infested Douglas-fir trees were partially caged to determine the emergence period and beetle production. Beetles began emerging in April, but emergence peaked between 10 and 26 June. In 1987 and 1988 beetle emergence averaged 20 or more per sq. ft. of bark. Annual growth of the infested trees showed a decline prior to the beetle outbreak followed by an increase during the outbreak.


Effects Of Prairie Dog Rodenticides On Deer Mice In Western South Dakota, Michele S. Deisch, Daniel W. Uresk, Raymond L. Linder Dec 1990

Effects Of Prairie Dog Rodenticides On Deer Mice In Western South Dakota, Michele S. Deisch, Daniel W. Uresk, Raymond L. Linder

Great Basin Naturalist

Mortality of nontarget small mammals was determined after application of three black-tailed prairie dog (Cynomys ludovicianus) rodenticide treatments (prebaited zinc phosphide, prebaited strychnine, and strychnine alone) in western South Dakota. Immediate (September 1983) and long-term (September 1983 through August 1984) impacts on deer mouse (Peromyscus maniculatus) relative densities were evaluated and the three rodenticide treatments were compared for efficacy. The three treatments had no significant (α < .10) immediate impacts on deer mouse relative densities, although zinc phosphide did lower them; that impact was not, however, long term. Long-term impacts of the two strychnine treatments were variable, with an increase in deer mouse densities with the strychnine only treatment. Overall, comparisons among the three treatments indicated that zinc phosphide was more effective than either strychnine treatment in reducing deer mouse densities.


Ecological Review Of Black-Tailed Prairie Dogs And Associated Species In Western South Dakota, Jon C. Sharps, Daniel W. Uresk Dec 1990

Ecological Review Of Black-Tailed Prairie Dogs And Associated Species In Western South Dakota, Jon C. Sharps, Daniel W. Uresk

Great Basin Naturalist

Black-tailed prairie dogs (Cynomys ludovicianus) once occupied extensive areas throughout the Great Plains. In recent years massive control programs have been initiated to reduce prairie dog populations, primarily to benefit the livestock grazing industry. Currently in western South Dakota most prairie dogs are found on public lands. Control programs using toxicants for prairie dogs have been found to be economically unfeasible when not combined with reductions in livestock grazing. Control programs also have negatively impacted some nontarget species of birds and small mammals. Livestock grazing is directly related to prairie dog densities. Prairie dog and livestock grazing activities …


On The Typification Of Oxytropis Borealis Dc., Stanley L. Welsh Dec 1990

On The Typification Of Oxytropis Borealis Dc., Stanley L. Welsh

Great Basin Naturalist

The status of the name Oxytropis borealis DC. is reviewed as it applies to North American plants. A summary of the infraspecific taxa is presented, and several nomenclatural combinations are proposed: Oxytropis borealis DC. var. hudsonica (Greene) Welsh; O. borealis var. sulphurea (Pors.) Welsh; O. borealis DC. var. viscid (Nutt.) Welsh. One new taxon, Oxytropis borealis DC. var. australis Welsh, is described from Utah and Nevada, USA.

Reproduction Of Three Species Of Pocket Mice (Perognathus) In The Bonneville Basin, Utah, Kenneth L. Cramer, Joseph A. Chapman Dec 1990

Reproduction Of Three Species Of Pocket Mice (Perognathus) In The Bonneville Basin, Utah, Kenneth L. Cramer, Joseph A. Chapman

Great Basin Naturalist

Data on reproduction of three species of pocket mice (Perognathus) occurring in northern Utah are summarized. Perognathus parvus and P. formosus bred in spring but not the remainder of the year. This occurred despite mild fall and winter temperatures and shallow snowcover. Litter sizes for P. parvus and P. formosus were similar to those reported by previous investigators. A small sample of P. longimembris indicated they may have much larger litters (averaging 5.78 young) than previously reported for laboratory populations. Adult body mass was positively correlated with testis mass in all species, and with litter size in P. …

Trampling Disturbance And Recovery Of Cryptogamic Soil Crusts In Grand Canyon National Park, David N. Cole Dec 1990

Trampling Disturbance And Recovery Of Cryptogamic Soil Crusts In Grand Canyon National Park, David N. Cole

Great Basin Naturalist

Cryptogamic soil crusts in Grand Canyon National Park were trampled by hikers, under controlled conditions, to determine how rapidly they were pulverized and how rapidly they recovered. Only 15 trampling passes were required to destroy the structure of the crusts; visual evidence of bacteria and cryptogam cover was reduced to near zero after 50 passes. Soil crusts redeveloped in just one to three years, and after five years the extensive bacteria and cryptogam cover left little visual evidence of disturbance. Surface irregularity remained low after five years, however, suggesting that recovery was incomplete.

Obstacles And Opportunities: Funding Research At The 1890 Land Grant Institutions, Alton Thompson Dec 1990

Obstacles And Opportunities: Funding Research At The 1890 Land Grant Institutions, Alton Thompson

Journal of Rural Social Sciences

Similar to other university faculties, faculty members at 1890 land grant institutions are expected to support their research programs with grants from sources outside their institutions. Although the expectation of securing grants has not received the public attention that the "publish or perish" dictum has, faculty at the 1890 institutions seeking promotion and tenure must increasingly demonstrate that they can procure grant funds. Numerous inhibitive factors, however, tend to attenuate the success of 1890 faculty in obtaining research grant funding and in implementing such research projects. In this study, three key factors are examined: political, research infrastructure, and faculty initiative. …


1890 Institutions' Extension Program And Rural Development, Adell Brown Jr. Dec 1990

1890 Institutions' Extension Program And Rural Development, Adell Brown Jr.

Journal of Rural Social Sciences

The black land-grant colleges' contributions to developing the rural South are traced back before they were added to the land-grant system by the passage of the Morrill Act of 1890. The 1890 Extension target clientele are small farmers and limited resource persons who were not being reached by the conventional delivery system. Before 1972, the 1890 institutions primarily assisted the 1862 universities to serve black farmers and provide training and housing for black specialists and agents. In 1972, the passage of USDA Appropriation Act, under 3(d) section of the Smith-Lever Act, provided funds for the 1890 institutions to fulfill the …


The Decline Of Black Farmers And Strategies For Survival, Robert Zabawa, Arthur Siaway, Ntam Baharanyi Dec 1990

The Decline Of Black Farmers And Strategies For Survival, Robert Zabawa, Arthur Siaway, Ntam Baharanyi

Journal of Rural Social Sciences

By most accounts, black farmers in the United States are categorized as either limited resource or subsistence producers given an historic lack of access to credit, mechanical, and land resources. Additionally, advanced age and limited education have placed black farmers on the "endangered" list. Given these constraints to financial and human capital, black farmers have adopted survival strategies in an attempt to maintain their farms. Results presented here from research conducted in the Black Belt region of Alabama indicate that there is a high degree of participation in the off-farm workforce and reliance on off-farm income for black farm family …
