Data from: Yellowstone bison—should we preserve artificial population substructure or rely on ecological processes?

Halbert et al. (2012) analyzed microsatellite genotypes collected from 661
Yellowstone bison sampled during winters from 1999 through 2003 and
identified 2 genetically distinct subpopulations (central, northern) based
on genotypic diversity and allelic distributions. Based on these findings,
they raised concerns about the management and long-term conservation of
Yellowstone bison due to disproportionate culling of the 2 subpopulations
in some winters. The data and findings of Halbert et al. (2012) are
significant and useful for managers charged with conserving these iconic
wildlife. However, their article provides information regarding the
behavior and management of Yellowstone bison that does not accurately
portray historic or current conditions. This response clarifies those
conditions and challenges some of their apparent deductions and
recommendations.
