  Authors:Catherine Lambert Koizumi and Andrew E. DerocherFrom:PLoS ONE (Vol. 14, Issue 4) Peer-Reviewed

  Apr. 15, 20196,842 words Report 1570LThe abundance of ungulate populations may fluctuate in response to several limiting factors, including climate, diseases, and predation. In the northern Richardson Mountains, Canada, Dall sheep (Ovis dalli dalli) have...

• Correlated cycles of snowshoe hares and Dall's sheep lambs

  Authors:J.F. Wilmshurst, R. Greer, and J.D. HenryFrom:Canadian Journal of Zoology (Vol. 84, Issue 5) Peer-Reviewed

  May 20065,802 words Article 1670LAbstract: We tested the hypothesis that the number of surviving lambs counted in mid-summer from a Dall's sheep (Ovis dalli Nelson, 1884) population on Sheep Mountain, Yukon, Canada, is correlated to the density of...
