Appendix A. Data sources for elk pregnancy rates.

greer1964.htm - The greer1964.htm file is of a conference presentation (Greer, K., and E. Howe. 1964. Winter weights of northern Yellowstone elk, 1961-62. Transactions of the North American Wildlife Conference 29:237–248). Table 2, page 239 provides data on midwinter changes in elk eviscerated body mass on the northern range of Yellowstone from the winter of 1961–1962.
greer1965.htm - The greer1965.htm file is of a Pittman-Robertson Job Completion Report (Greer, K. 1965 Job completion report, project W-83-rm Job III-B. Collections from the Gallatin elk post season 1964–1965. 1965. Montana Department of Fish, Wildlife & Parks, Helena, Montana). Table 4, page 10 provides data on mid-winter pregnancy rates in the Upper Gallatin elk herd in 1964–1965.
greer1966.htm - Thegreer1966.htm file is of a conference presentation (Greer K. 1966. Fertility rates of the northern Yellowstone elk populations. Proceedings of the Annual Conference of the Western Association of Game and Fish Commissioners 46:123–128). Table 2, page 125 provides data on northern Yellowstone elk pregnancy rates for 5 years, from the winter of 1961–1962 through the winter of 1965–1966. These data overlap with those presented in greer1964.htm (above).
greer1967.htm - The greer1967.htm file is of a Pittman-Robertson Job Completion Report (Greer, K. 1967. Wildlife investigations laboratory: Special collections - Yellowstone elk study, Project W-83-R-10, Job B-1. 1967. Helena, Montana department of Fish, Wildlife & Parks). Table 4, page 5 provides data on northern Yellowstone elk pregnancy rates in the winter of 1966–1967.
peek1967.htm - The peek1967.htm file is of a Pittman-Robertson Job Completion Report (Peek, J. 1967. Job completion report, project W-73-R-12 Job A1.1 Gallatin big game studies. Montana Department of Fish, Wildlife & Parks, Helena, Montana). Table 6, page 6 provides information on mid-winter pregnancy rates in Upper Gallatin herd elk in 1964–1965 and 1966–1967. These data overlap with those presented in greer1965.htm (above).
zager2005.htm - The zager2005.htm file is of a report from Idaho Fish and Game (Zager, P., C. White, and G. Pauley. Elk ecology: factors influencing elk calf recruitment. Project W-160-R-32, subproject 31. 2005. Idaho Department of Fish and Game). This report can also be found at the Idaho Fish and Game website (http://www.fishandgame.idaho.gov). Table 1, page 16 provides data on elk pregnancy in capture cows, while Table 4, Page 19 provides data on pregnancy from fecal collections. The methods section provides details on the temporal and spatial aspect of the predator treatment during this study.
garrott2009.htm - The garrott2009.htm file is a quote from the last paragraph on page 502 in Garrott, R., P. J. White, and J. Rotella. 2009. The Madison headwaters elk herd: transitioning from bottom up regulation to top down limitation. Pages 489–517 in R. Garrott, P. White, and F. G. R. Watson, editors. The ecology of large mammals in central Yellowstone. Elsevier, San Diego, California, USA.
