Genetically, Bison Don't Measure Up to Frontier Ancestors- April 2002 By MARK DERR (NYT) ABSTRACT - Genetic study led by Texas A&M geneticist Dr James Derr finds that more than 90 percent of private bison and many animals in publicly owned herds are actually bison-cow hybrids; finding reduces pool of pure bison available for preserving species to fewer than 15,000 animals.

Spatial Aspects of Bison Density Dependence in Yellowstone National Park- October 2000 This paper capitalizes on a unique opportunity provided by the record of the bison population of Yellowstone National Park (YNP). This population has been intensely monitored for almost four decades. There does not appear to be another comparable data set in existence for a very large highly gregarious herbivore (G. Caughley pers. comm. to MM). This population has a long historical record with some information dating back to 1860 (Meagher 1970, 1973). Further, the YNP bison herds have been the subject of long-term detailed and continuous ecological study since 1963. (PDF, 133 pages, 2.6MB)
