An hypothesis that there was no relationship between Insects and cattle g razing was tested. The study was conducted on pastures that were stocked lightly (S.L.), moderately (2x), and heavily (3x). The pastures were also grouped in to 2 blocks...
Invasion by nonnative plants is particularly prevalent in wetlands. While the ecological patterns in wetland plants are well known, it is less well known how flooding-related soil conditions influence the physiological success of introduced species...
I investigated the use of riparian areas along the North Fork of the Solomon River and Bow Creek on Kirwin National Wildlife Refuge by migrating birds during the spring of 1997. One banding site and two bird census transects were set up along each...
The Kansas River System currently represents the western range limit for 9 species of freshwater mussel, although 24 species were reported historically. The purpose of this study was to assess the current status of native mussels (Unionidae) and...
The Ranegras Plain basin is a northwest trending alluvial basin located in western Arizona. Groundwater within the basin occurs in Tertiary deposits and Quaternary alluvium. The Tertiary deposits are composed primarily of clay, probably of...
Herbage dynamics of three plant communities were estimated from June, 1971, to May, 1972, on a Mixed Prairie grassland in Trego County, Kansas. Specific functional attributes estimated were: (1) net primary production, (2) productivity rates, and...
Texas horned lizard (Phrynosoma cornutum) populations have been in steady decline over the past twenty years due to habitat loss, pesticide use, the pet trade, and invasion of the red imported fire ant (Solenopsis invicta). At Aransas National...
Studies that have compared levels of activity with intelligence quotient scores have been contradictory results ranging from negative through strong positive relationships between the two variables. The present study is an attempt to provide a...
Continuous removal trapping in three areas of study yielded information regarding the emigration of small mammals from peripheral areas. Two of the trap lines were operated for 80 consecutive days during the summer months of 1966 and one trap line...
Microhabitat associations among small mammals and between mammals and ground cover were investigated in 1989 as part of a federal program to survey the ecology of military installations. The survey was conducted on Pinon Canyon Maneuver Site,...
The objectives of this study were (1) to describe the species diversity of the vegetaiton occurring throughout the various siol series sampled, (2) to determine the presence of absence of any “indicator species”, and (3) to delineate major...
An investigation was made to determine the role of pelage color of Peromyscus maniculatus nebrascensis in relation to the type of soil and the vegetation the Nebraska deermouse inhabits. P.M. nebrascensis displays several different shades of pelage...
The relationship of physical attractiveness and locus of control in 126 elementary school children, grades three through six, was investigated. The study was an attempt to replicate, with children, the results found by Anderson (1978) for college...
The purpose of this study was to examine selected aspects of the life history and autecology of slimflower scurfpea (Psoralea tenuiflora Pursh.). To measure growth rate and phenology, naturally occurring seedlings were marked after germination in...
[The extent of competition between deer mice, Peromyscus maniculatus, and western harvest mice, Reitbrodontomys megalotis, was assessed by a species removal experiment conducted on a relict grassland in Ellis County, Kansas. Vegetation was sampled...
Small mammal populations were censused during a seven-month period at five Conservation Reserve Program plots in Rooks County, Kansas. Sites in the Solomon River Valley selected for this study were seeded with grasses in successive years...
Seven habitats were sampled from March through October 1991. Five study sites (alfalfa, grain sorghum, winter wheat, corn, and soybean) represented the principal agricultural crop types of Kansas. The remaining two study sites, a fencerow bordered...
The small mammal populations of fencerows and crop field borders were sampled in an agricultural-grassland mosaic of west-central Kansas. Farming is a dryland, 3-year rotation of wheat, grain sorghum, and fallow. Two sites were sampled, one on the...
The status of freshwater mussels (Bivalvia: Unionoidea) has declined over the last 30 years such that they are one of the most imperiled taxonomic groups in North America. Mussel populations in Kansas have followed a similar trend of decline. To...
The taxonomic relationship of two supposed species of Geomys in northern Kansas was assessed using morphometric, bacular, karyotypic, and electrophoretic analyses. Only morphometric analysis proved useful in differentiating between the taxa. No...
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...
During the summer of 1980, a baseline sampling of the herpetofauna of an eight square mile tract of sandsage prairie in southwestern Kansas was conducted. Seven trapping methods were employed: drift fence-pit traps; pitfall traps; funnel traps;...
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.
