Geomorphology, Quaternary Stratigraphy, and Geoarcheology of Fox Creek Valley, Tallgrass Prairie National Preserve, Northeast Kansas
A geomorphological investigation was conducted in Fox Creek valley within the Tallgrass Prairie National Preserve, Chase County, Kansas. During the first stage of the study, Quaternary landforms were defined and mapped in the valley. This was followed by inspection of cutbank exposures along the creek and deep coring across the valley floor. Subsurface information gleaned from the exposures and...
متن کاملTallgrass Prairie: Remnants and Relicts
The tallgrass prairie once was continuous throughout the eastern Great Plains. Now, scattered remnants remain. The distribution of some of the most interesting and socially valuable remnants occur along the base of the Rocky Mountains as relicts from a past era. When the species composition of these Colorado grasslands is compared with that of the eastern tallgrass prairie by an index of simila...
متن کاملEdge Effects on Nesting Dickcissels (Spiza americana) in Relation to Edge Type of Remnant Tallgrass Prairie in Kansas
—Edge effects on grassland-nesting birds should be less pronounced or absent near cropland edges of grasslands that lack wooded-edge habitat often used by nest predators and brood parasites. We compared nest predation, brood parasitism and densities of dickcissel (Spiza americana) nests in relation to distance from woodland and cropland edges of Kansas tallgrass prairie. Daily nest predation ra...
متن کاملHabitat edge, land management, and rates of brood parasitism in tallgrass prairie.
Bird populations in North America's grasslands have declined sharply in recent decades. These declines are traceable, in large part, to habitat loss, but management of tallgrass prairie also has an impact. An indirect source of decline potentially associated with management is brood parasitism by the Brown-headed Cowbird (Molothrus ater), which has had substantial negative impacts on many passe...
متن کاملHabitat Use by Nesting Grassland Birds and Their Snake Predators in the Tallgrass Prairie
Grassland bird populations have seen greater declines than any other group of birds in North America. Although snake predation is considered the primary reason for nest failure, little is known about how management practices in the Flint Hills region of Kansas impact movement and habitat use of snakes, and the predator-prey interaction between snakes and nests of grassland birds. Radio telemetr...
