We studied kill rates by wolves (Canis lupus) on a rapidly growing moose population in the east-central Yukon. We added these data to the cumulative functional response curve obtained in other North American wolf studies. Our kill rates are higher than those predicted at low moose densities. The kill rate increases rapidly, reaching 2.4 moose per wolf per 100 days at 0.26 moose/km2 and remains constant at this level. No data are available below 0.2 moose/km2 to indicate the shape of the ascending curve. Based on moose distribution and the low prey-switching ability of wolves, we suggest that the functional response curve is of type II. Our wolf predation rate model predicts that moose are held to a low density equilibrium...

"The population estimate for the western Yukon Flats in Game Management Unit (GMU) 25D (2,269 square miles) was 528 moose with a certainty of +/- 25% at the 90% confidence level."--P. 2.

An aerial moose (Alces alces) population survey was completed on Tetlin National Wildlife Refuge and the northeast corner of Game Management Unit 12 from 4 – 11 November 2004. We estimated the population at 1,272 moose for the 7,651 km2 (2,954 mi2 ) survey area. Overall density was 0.17 moose/ km2 (0.43 moose /mi2 ). The estimated ratios of bulls, yearling bulls, and calves per 100 cows were 69.8, 16.2, and 47.8, respectively. Bulls made up 31.9 % of the population, cows 45.8%, and calves 21.9

We investigated causes of mortality and the physical condition of moose (Alces alces gigas) in a multiple-predator system in eastern interior Alaska, USA, from 1998 to 2000. We identified the sources of mortality of calf and cow moose and collected fecundity and fitness data to obtain information on range quality and carrying capacity. Radiocollars were placed on 30 cow moose in 1998 and on 62 moose calves in 1998 (n = 29) and 1999 (n = 33). Estimates of fecundity and fitness parameters indicated that reproductive potential for moose was high, with a twinning rate of 63%, a pregnancy rate of 89%, and above-average body sizes of female and neonate moose. We inferred that range quality may not be a significant limiting...
