Effects of moose movement and habitat use on GPS collar performance
Article Abstract:
A radiotelemetry collar with GPS (global positioning system) unit was evaluated for accuracy and effectivity. Calibration of the unit involved comparing the readings from the unit with differentially-corrected GPS locations that were under various types of cover and subsequently tested on a free-ranging moose. The GPS unit provided a better than 90% chance of detection/location on grounds with no/thin cover, 60-70% in heavy canopies, with a confidence value of 45m in 50% of the readings and 100m in 95% of the readings.

Fecal progestagen concentration as an indicator of the estrous cycle and pregnancy in moose
Article Abstract:
A noninvasive method for monitoring ovarian activity that would allow effective estimation of the estrous cycle and pregnancy in mosse, Alces alces, is presented. Radioimmunoassay of fecal samples from nonpregnant yearling females on their 3-4 estrous cycles and from three pregnant adult cows showed varying progestagen levels. The results provide evidences that monitoring the nadir of progestagen metabolites may be an effective indicator of estrous activity and pregnancy in moose.

Reproductive characteristics of Alaskan moose
Article Abstract:
A study of the reproductive characteristics of the moose (Alces alces) by the Moose Research Center (MRC) on the Kenai Peninsula in Alaska reveals the gestation time, estrous cycle, estrous length, fetal development and the birth mass of calves. The study of the development of the moose-fetus helps to estimate the chronology of conception. The size-sex ratio and the mass of calves born under different conditions are also studied.
