Percentage composition and percentage frequency of grasses and forbs were...
The soils under four small plant communities were studied to determine the cause of vegetation heterogeneity within a designed Buchloe-Bouteloua community. Sixteen relicate stands, four each of big bluestem (Andropogon gerardi), western wheatgrass...
This investigation was an attempt to determine the vigor of various types of range grasses under different intensities of clipping. Three range grasses selected for study were: (1) a tall grass, big bluestem (Andropogon gerardi Vitman); (2) a...
Various grassland bird species have exhibited population declines over the past 60 years. Recent interest in understanding the causes for the decline in grassland birds has prompted numerous research studies. Several studies have focused on changes...
An ordination of stands of remnant vegetation according to soil similarities shows that water-retaining capacity and organic matter vary directly while available nutrients generally vary inversely with rock content.
The composition of dry stands...
"The phenotype of two Andropogon gerardii subspecies, big bluestem and sand bluestem, varies broadly throughout the Great Plains of North America, giving rise to ecotypes within the species. This study sought to discriminate between genetic and...
This investigation was an attempt to determine the seasonal development and seed production of the major grasses in areas which had been subjected to different intensities of grazing in past years. The grasses used in this study were (1) buffalo...
Home- range size, population density, distributions, and territoriality of small mammals were studied from April through August of 1965, in a relict grassland area 1.5 miles southwest of Hays, Ellis County, Kansas. Home ranges were determined from...
Mixed prairie range sites vary in ability to produce for age for livestock consumption. One reason for the difference in variation is the degree of utilization of the ranges in past years. The purpose of the study was to determine variation in...
A study was made to determine the effects of two soil moisture levels, field capacity and the permanent wilting percentage, on the total sugar content of the foliage of blue grama (Bouteloua gracilis), western wheatgrass (Agropyron smithii), and...
A six-months microclimatic investigation (November, 1957 to April, 1958) of the various climatic factors (temperature, light intensity, wind velocity, and humidity) was conducted at seven different stations. The area selected for this study was a...
Percentage composition by species is an important measurement used in range ecology. It can be based on either basal cover or forage production. Most range managers are interested in composition based on production although composition by basal...
This investigation was an attempt to determine the effects of a change of habitat factors on the responses of big bluestem which dominates favorable site in the mixed prairie association. Responses of big b1uestem on five habitats were determined...
The purpose of this study was to determine some soil-vegetation relationships of a blue shale-limy upland range site which is a complex of five different soils.
Soil texture, percent organic matter, available P2O5 exchangeable K20, wilting point,...
The purpose of this study was to determine the soil vegetation relationships on a chalk flat range site in Gove County Kansas. The research area used in this study was located in the north half of section 33, township 14 south, range 31 west...
Studies of European limestone grasslands have suggested that when relatively small scale is considered, these grasslands are the most floristically rich sites on Earth. This study of shallow limestone communities in western Kansas was designed to...
Exclosures have been used for some time in plant ecology, particularly in the study of regeneration and re-vegetation. This study had two main purposes. One was an attempt to use long-established exclosures to determine the effect of moderate...
The study area, having a total of 434 acres, was placed in the "Soil Bank" in 1958.
A sorghum cover crop was seeded in spring of 1959 and the area was seeded to grass on November 25, 1959.
Rate and mixture of seeded grasses were as follows: three...
The purpose of this study was to investigate the effect of soapweed on emergence, germination, and growth of six native grass species.
Treatments were Yucca mulch, Yucca seeds, and soil from around Yucca plants. Grass species were buffalo grass,...
A two-year project was initiated in 1974 to study the effects of a late spring burn on three ungrazed, Mixed Prairie range sites. The six study sites were located on federal property surrounding Wilson Reservoir, Russell County, Kansas. Differences...
An investigation to determine the effects of cattle exclosures on the habits and activities of small mammals within and surrounding these protected areas was conducted from September to November of 1958.
Four exclosures located in a 750 acre...
A study was made to determine what effect various intensities at clipping had upon yield, basal cover, and growth at 3 pasture types near Hays, Kansas. The study was conducted for 2 growth seasons (1955 - 1956) on a bluestem dominated, a reseeded,...
The purpose of this investigation was to analyze the distribution and vegetative composition of remnant grasslands on shale-limestone parent materials of the Central Kansas Rolling Plains Region in Kansas. The floristic composition of each stand...
North- and south-facing slopes were studied to determine differences in vegetation and microclimate. Vegetation was analyzed by line transects. The study on microclimate included soil and air temperatures, evaporation, light intensities, and wind...
The purpose of this study was to determine effects of mowing and grazing on native vegetation of grasslands compared to a relict area. Three areas were selected in relation to past treatment: relict, mowed and moderately grazed. On each area two...
Three pastures located 2.5 miles southwest of Hays were selected to determine the relationship of vegetation to depth of soil and different intensities of grazing. The pastures were classified as non-grazed, moderately-grazed, and heavily-grazed...
One-hundred and fifty modified step-points were taken on each o f 100 sample locations on a 244 ha (610 acre) prairie in Webster Co., Nebraska. From this technique, percent basal cover and percent species composition were obtained at each sample...
