Two recent papers related to the Younger Dryas Impact Hypothesis are:

Woodman, N., and N. B. Athfiel, 2009, Post-Clovis survival of
American Mastodon in the southern Great Lakes Region of North
America. Quaternary Research. vol. 72, no. 3, pp. 359-363.

One statement in the paper is:

"Previous study of relative numbers of preserved spores of
the dung fungus Sporormiella, used as a proxy for megafaunal
biomass, suggests that populations of large mammals were in
steep decline in northeastern North America before the onset
of the YDC."

Another paper in the same issue is:

Newby, P., J. Bradley, A. Spiess, B. Shuman, and P. Leduc,
2009, A Paleoindian response to Younger Dryas climate change.
Quaternary Science Reviews. vol. 24, no. 1-2, pp. 141-154.
