The prevalence, mean number, and mean total weight of Echinococcus granulosus cysts in the lungs of moose increased with moose density in southwestern Quebec. Such responses in the level of infection were documented in areas of 0.17, 0.23, and 0.37 moose/km2. The increase of E. granulosus infection in moose was attributed to higher densities of wolves, the definitive host of this parasite, as well as an accompanying increase in the rate of wolf predation upon moose. The aggregated distribution of this parasite within the moose population is considered to reflect the highly heterogeneous use of space by wolves and the consequent aggregated distribution of parasite eggs within the environment. A possible regulatory effect of E. granulosus infections on moose numbers is discussed.

Abstract Since 1998, 83 female moose Alces alces have been captured and instrumented with radiocollars as part of a population dynamics study in southwestern Alaska. Moose were pursued and immobilized with carfentanil citrate and xylazine HCl administered from a dart gun fired from a helicopter. We investigated the potential for capture and radiotelemetry instrumentation to alter calf production or recruitment of 78 radiocollared adult female moose. Calf production or recruitment by radioed females was not significantly different between capture and noncapture years (P < 0.290; P < 0.789, respectively). We recommend the continued use of these capture and immobilization methods for deploying radiocollars to study moose population dynamics in this region.

Role Management

Abundant forage, particularly twigs of deciduous species, represents the key element of K carrying capacity for moose. Forest fires previously created such quality habitat, while timber harvest should now play a comparable role. Management units for moose habitat should cover 40-50 km2. Hunting and predation represent the regulating factors of most moose populations in Québec and Ontario, so that habitat is only lightly used. This situation poses difficulties in evaluating the role played by forestry practices on population dynamics; however the logging of a new area, which creates accessibility and removes much cover, greatly exposes moose to hunting until regrowth again provides a visual screen. Moreover, the increasing use of herbicide in forestry, to eliminate deciduous species, represents a potential threat for moose habitat.
