Community Composition Of Dry Prairie In Iowa And Southeast Nebraska, Thomas R. Rosburg
Community Composition Of Dry Prairie In Iowa And Southeast Nebraska, Thomas R. Rosburg
Journal of the Iowa Academy of Science: JIAS
Results from quantitative research on the community composition of dry prairies across Iowa were consolidated from three different studies completed since 1983. Information is provided on the distribution and abundance of 204 dry prairie species. The most abundant species included little bluestem (Schizachyrium scoparium (Michx.) Nash), big bluestem (Andropogon gerardii Vitman), side-oats grama (Bouteloua curtipendula (Michx.) Torrey), prairie dropseed (Sporobolus heterolepis (Gray) Gray) and Kentucky bluegrass (Poa pratensis L.). Multivariate analyses were completed using two independent measures of species abundance-relative cover and community constancy. When relative cover was used to determine community composition, the abundance of graminoids (tallgrasses vs. mid-grasses) …
Slavery In The Platte Region, H. Jason Combs
Slavery In The Platte Region, H. Jason Combs
Nebraska Anthropologist
Missouri's bid for statehood reflected the struggle to extend the southern slave culture onto the western frontier of settlement. The Northwest Ordinance of 1787 and the Missouri Compromise set specific geographic boundaries for the extension of slavery, which in turn created distinctive patterns of migration and settlement on the frontier. The Platte Purchase region of northwest Missouri is one of the areas that reflect slavery's influence on settlement. This paper will discuss slave ownership, the need for slavery, and explain the geographic distribution of slaves in the Platte region.
