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 …

Museum Studies In Collection Management, Hugh H. Genoways

University of Nebraska State Museum: Programs Information

First paragraph:

At the workshop on "Collection Resources for the 1990's" held in Washington, D.C., October 1988, one of the identified needs for institutions was for additional trained collection management staff (Hoagland and Mabee, ASC Newsletter 16(6): 9, 1988). There are few academic programs that provide training in the management of biological, geological, and anthropological collections. Because this is an identified need for the 1990's, the question arises: "Are we able to meet this need?" and, if we are not currently in a position to do so, "What must be done in the future to meet this need?"

Tillage And Fertilizer Influences On Corn And Legume Cover, J. E. Gilley, J. F. Power, P. J. Reznicek, S. C. Finkner

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The use of legumes in a cropping system may provide a variety of benefits. In this study, the effectiveness of selected legume species in providing surface cover was examined. The legumes were interseeded into either conventional or no-till corn, with or without N fertilizer. Both maximum legume cover and maximum cover furnished by corn plus legumes were examined. Mean cover provided during the study period by both the cover crop, and corn plus cover crop was also determined.

Can Genetically Engineered Crops Become Weeds?, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

There are significant differences if the distribution of weedy characteristics among weeds, normal plants, and crops. The world’s most serious weeds possess on the average 10 or 11 of these characters, a random collection of British plants have an average seven of the traits, and crop plants only five. For the average crop to become as “weedy” as the average weed, it would need to acquire five weedy traits. Even using the unlikely assumption that those traits are single loci in which a dominant mutation would provide the weedy character, this would require the simultaneous acquisition of five gene substitutions. …

An Alternative Approach For Evaluating The Efficacy Of Potential Biocontrol Agents Of Weeds. 2. Path Analysis, Dan J. Pantone, William A. Williams, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Path analysis was used to assess the efficacy of the fiddleneck flower gall nematode as a weed biocontrol agent of coast fiddleneck in competition with wheat during two years of field experiments. The path analysis revealed that the number of inflorescences/plant for fiddleneck and the number of heads/plant for wheat were the most important yield components that determine fecundity and seed yield. The density of fiddleneck had a much greater impact on the yield components of fiddleneck than did the density of wheat or the nematode rate of inoculation. The nematode had its greatest negative impact on the number of …

Index Selection For Components Of Litter Size In Swine: Response To Five Generations Of Selection, S. M. Neal, R. K. Johnson, R. J. Kittock

Department of Animal Science: Faculty Publications

Selection for an index of ovulation rate (OR) and embryo (fetal) survival rate (ES) to 50 d of gestation (I = 10.6 x OR + 72.6 x ES) was practiced for five generations in a line that was a composite population of the Large White and Landrace breeds of swine. A control line sampled from the same population was selected randomly and mated. Ovulation rate and number of fetuses (FETS) were measured by laparotomy and ES was calculated as FETS/OR. The select line averaged 43 litters by 18 sires and the control line averaged 42 litters by 15 sires per …

Beaver And Beaver Dam Removal In Wisconsin Trout Streams, Larry Dickerson

Eastern Wildlife Damage Control Conference: 4th (1989)

Beaver (Castor canadensis) dam building activities create many long-term affects on stream ecosystems. Beaver dams may negatively influence trout fisheries by creating physical barriers to spawning areas, increasing sediment retention, and increasing water temperatures. The U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) Animal Damage Control (ADC) program in Wisconsin, entered into cooperative agreements with the Wisconsin Department of Natural Resources (WDNR) and the U.S. Forest Service (USFS) on the Nicolet National Forest from June through September, 1988, to remove beaver and beaver dams from priority classed trout streams. Four hundred and eight beaver …

Ecologically Sensitive Management Options For Bats, Paul B. Robertson

Eastern Wildlife Damage Control Conference: 4th (1989)

Over the past decade, there has been a dramatic, positive shift in the public image of bats in the United States (Tuttle 1988a). This shift is particularly impressive in light of the inappropriate and poor public image that bats have suffered in most western nations in the last century. Over the past decade, a sizeable segment of the U.S. public, as well as local, state and national officials, have been educated to the ecological and economic value of bats which results from their insectivory and plant pollination activities (Olkowski and Olkowski 1989, Tuttle 1988b). The fact that they pose a …

Economic Impact And Control Of Wading Birds At Arkansas Minnow Ponds, Michael D. Hoy, Jeffrey W. Jones, Albert E. Bivings

Eastern Wildlife Damage Control Conference: 4th (1989)

Esophageal/stomach contents of 172 little blue herons (Egretta caerulea), great egrets (Casmerodius albus), snowy egrets (Egretta thula), and great blue herons (Ardea herodias) were analyzed to estimate their consumption of golden shiners. Mean and maximum number of golden shiners consumed/bird, as well as the mean total length of golden shiners consumed by each wading bird species was determined. Loss estimates varied by wading bird species and ranged from $0.10 - $1.12/bird/feeding. Loss estimates reflect the severity of problems with wading birds on minnow ponds and the need to reduce losses by use …

Population Dynamics And Management Of Deer In Wisconsin, Keith R. Mccaffery

Eastern Wildlife Damage Control Conference: 4th (1989)

Management of deer in Wisconsin is affected by a combination of biological and environmental factors. In the Northern Forest, winter severity dramatically affects annual survival and recruitment. However, deer density goals here are above "I" carrying capacity. Thus, minor errors in harvest management are in part compensated by herd responses. Deer in the farmland areas of the state are maintained at goals that for the most part are below "I" carrying capacity. Errors in harvest management are magnified in farmland because herd responses are not compensatory. Therefore, the harvest quotas for antlerless deer must be more precise in our farmland …

Population Dynamics And Harvest Response Of Beaver, Neil F. Payne

Eastern Wildlife Damage Control Conference: 4th (1989)

"For when we speak of the fur trade, we mean the beaver trade. Other furs were handled; others — notably the rich sea otter — were more valuable by far. But the beaver was the root and core of the trade ... Many men died, a continent was explored, an indigenous [human] race degraded and its culture crushed; all because beaver fur, with its tiny barbs, felted up better than any other" (Berry 1961:18).

The habits of beaver (Castor canadensis) allow them to be located and trapped readily, resulting in their extirpation from many areas. Beaver populations have …

Fertility Control As A Tool For Regulation Of Wildlife Populations, U.S. Seal

Eastern Wildlife Damage Control Conference: 4th (1989)

Biological control of reproduction and fertility is a normal part of the life history of all organisms. Control mechanisms allow timing of reproduction with respect to age, time of day, season, and other periodic environmental events. Further modulation can occur with variations in temperature, rainfall, nutrition, and health status. Interactions with other members of the species, ranging from pherohormonal stimulation of estrus to social delay of puberty and breeding to infanticide, provide further constraints upon fertility and recruitment. All of these processes ultimately act through molecular neuroendocrine mechanisms that are under genetic control and are subject to natural selection and …

The Water Vapor Conductance Of Squamate Reptilian Eggs: The Influence Of Scaling On Nesting Ecology., Louis A. Somma

Papers in Herpetology

Flexible-shelled eggs of squamate reptiles are strongly influenced by their surrounding microclimate, particularly the hydric conditions of the nest. The eggshell water vapor conductance of an egg can be an indication of its requirement for water from the nest. Ackerman et al. (1985. Physiol. Zool. 58:129-137) have described the scaling relationship for eggshell water vapor conductance (G_H2O) of flexible-shelled reptilian eggs (G_H2O = 981.8M^0.52). This scaling relationship was investigated with water vapor conductance data obtained from 8 species of lizards representing the families Iguanidae (Anolis carolinensis, A. sagrai, Sceloporus woodi, S. virgatus) …

United States Public Health Resources

Small-subunit rRNA sequences were determined for almost 50 species of mycoplasmas and their walled relatives, providing the basis for a phylogenetic systematic analysis of these organisms. Five groups of mycoplasmas per se were recognized (provisional names are given): the hominis group (which included species such as Mycoplasma hominis, Mycoplasma lipophilum, Mycoplasma puimonis, and Mycoplasma neurolyncum), the pneumoniae group (which included species such as Mycoplasma pneumoniae and Mycoplasma muris), the spiroplasma group (which included species such as Mycoplasma mycoides, Spiroplasma citri, and Spiroplasma apis), the anaeroplasma group (which encompassed the anaeroplasmas and acholeplasmas), and a group …

A Simplified Equation For Modeling Sediment Transport Capacity, S. C. Finkner, M. A. Nearing, G. R. Foster, John E. Gilley

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Sediment transport capacity for shallow overland flow was represented as a quadratic function of downslope distance using the assumption of a linear increase in overland flow discharge with downslope distance and an approximation to the Yalin equation for sediment transport capacity. The simplified equation for sediment transport applies to complex topography having uniform soil and management characteristics. The simplified equation accurately approximated the Yalin equation when calibrated using the average of the hydraulic shear stresses at the end of a constant slope reference profile and the end of the actual profile. The simplified equation is useful in deriving closed-form solutions …
