The ages of 77 adult Moose (Alces alces) killed by Gray Wolves (Canis lupus) during the period 1967–2011 in northeastern Minnesota were significantly older than those of a sample of 17,585 Moose killed by hunters in nearby Ontario. Our findings support those of earlier studies of protected Moose populations in national parks that found that Gray Wolves tend to kill disproportionately more older Moose.

A small herd of 15–31 caribou (Rangifer tarandus) inhabited a shoreline strip of habitat along Lake Superior from 1972 to 1983. By remaining near the shoreline, they were spaced away from the major distributions of wolves (Canis lupus) and lynx (Lynx canadensis) that hunted mainly inland for moose (Alces alces) and snowshoe hares (Lepus americanus), respectively. Lake Superior also provided a means of escape from wolves, and offshore islands constituted safe parturition sites. The persistence of this herd is consistent with the hypothesis that viable caribou populations cannot survive on ranges frequented by high numbers of wolves (maintained mainly by moose prey) unless there are special habitat features providing escape for cows with young calves.

Efficacy Of Treatment

Roadside mineral licks form when road salt used to de-ice highways in winter runs off road surfaces and accumulates in roadside ditches. Some ungulates are attracted to these roadside licks as they seek to satisfy their mineral requirements. Within the distribution of moose (Alces alces (Linnaeus, 1758)) in North America, motorists often encounter moose visiting roadside licks in mid-summer, with many jurisdictions reporting summer peaks in moose-vehicle collisions (MVCs) at these locations. Our research used camera traps to monitor moose visitation of 22 roadside locations (including roadside licks, roadside ponds, and dry roadsides) in central British Columbia, Canada from December 2009–July 2020, tested the efficacy of treatment (decommissioning) methods used to reduce moose visitation to roadside licks, and roughly estimated decommissioning costs. Moose visitation to roadside licks was greatest from May–July. As we hypothesized, untreated licks were visited more often by moose than decommissioned licks, roadside ponds (absent of road salt), and dry roadsides. Decommissioning roadside licks by replacing or mixing lick waters and soils with materials, such as riprap, cedar mulch, pine logs, or dog (Canis lupus familiaris (Linnaeus, 1758)) fur and human (Homo sapiens (Linnaeus, 1758)) hair, is an effective and inexpensive means of reducing moose visitations to roadside areas and should increase motorist safety where roadside licks are visited by moose.

This report documents a group of 19 Wolves (Canis lupus) in northwestern Ontario. This is the largest group observed since record keeping in the Moose Aerial Inventory commenced in 1995. This large group may be a response to a high Moose (Alces alces) population in the Red Lake area.

Profit Maximisation

Abstract During the last few decades, the grey wolf (Canis lupus) has re-colonised Scandinavia. The current population counts some 430 individuals. With the wolf re-colonisation, several conflicts have arisen. One important conflict is due to wolf predation on moose (Alces alces). This conflict is studied under the assumption of landowner profit maximisation as well as routinised harvesting behaviour. The analysis emphasises how compensation for the predation loss affects landowner management and harvest profitability. The solutions to the landowner problems are also compared to the overall (social planner) management situation, where traffic costs due to moose–vehicle and railway collisions are included.

Ratio Dependent

The controversy over whether wolves (Canis lupus) can regulate ungulate numbers is difficult to assess, owing to data limitations, relaxation of predator control, and the fact that current predator – prey theory was developed from the study of invertebrate populations. A ratio-dependent predator – prey model appears to be supported by data on predation on ungulates, and the data indicate that wolves have a significant impact on numbers of moose (Alces alces), and thus can exert a regulatory effect on that species.
