A Chromosome Study Of Blue Grama (Bouteloua Gracilis) In Northern Colorado, T. Tsuchiya, W. Mcginnies, A. Shahla

Great Plains Research: A Journal of Natural and Social Sciences

Chromosomes were studied in somatic cells of 60 plants of blue grama, Bouteloua gracilis (Willd. ex Kunth) Lag ex Griffiths, collected from a 7-hectare field of native range at the Central Plains Experiment Range (CPER), Nunn, Colorado, to determine chromosome constitution in relation to the plant characteristics. Somatic chromosomes were studied in root tips collected from vigorously growing plants in the greenhouse. Acetocarmine squash method was used to make slide preparation. The majority of the plants were 2n =40. However, three plants were 2n=50 and two were 2n=60. The pentaploid plants (2n =50) were recorded for the first time in …


Review Of Cheyenne Bottoms: Wetland In Jeopardy By John L. Zimmerman, John Janovy Aug 1992

Review Of Cheyenne Bottoms: Wetland In Jeopardy By John L. Zimmerman, John Janovy

Great Plains Research: A Journal of Natural and Social Sciences

The Cheyenne Bottoms, Barton County, Kansas, has long been hallowed ground for birders and scientists as well as hunters. The dikes let one drive slowly through the marshes, scanning the flats for favorite sandpiper species and experiencing first hand the isolation of the central Kansas prairies. John Zimmerman, professor of biology at Kansas State University, had captured the Cheyenne Bottoms aura in eloquent prose, giving us a taste of wetlands natural history, while bringing to life the political and economic conflicts surrounding Arkansas River, and Walnut Creek, water. In many ways, the Cheyenne Bottoms case is a modern archetypical prairie …

The Utsa Boulevard Project: Archaeological Survey Along Leon Creek In Northwest San Antonio, Texas, Herbert G. Uecker Jan 1992

The Utsa Boulevard Project: Archaeological Survey Along Leon Creek In Northwest San Antonio, Texas, Herbert G. Uecker

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

A tract of land in northern San Antonio was briefly examined by the Center for Archaeological Research (CAR), The University of Texas at San Antonio (UTSA). Several prehistoric archaeological sites had previously been recorded and test excavated within or near the property. Remnants of two of those sites (41 EX 47 and 41 EX 231) within the study area were rediscovered and subjected to limited subsurface testing. At 41 EX 231, what are apparently well-preserved prehistoric cultural deposits were identified. Thus, it is recommended that additional intensive excavations be performed prior to any future disturbances at that site, or that …

Galliformes Specialist Group and Affiliated Societies: Newsletters

The purpose of the newsletter is to receive details of new projects, re-assessments of the status of relevant species, interesting discoveries or observations, taxonomic changes, conservation successes or threats and anything else that members might find interesting. We would like in future issues to produce a list of relevant publications which appear during the year in order to keep members up-to-date with current information. We will publish requests for contacts or information, advertisements for conferences and workshops and news of projects and project proposals.
