A study of the interactions between moose (Alces alces), elk (Cervus canadensis) and buffalo (Bison bison) was carried out during the summer of 1959 in Elk Island National Park, Alberta. The interactions studied were the possibility of competition for food and habitat, transmission of disease and dominance relations. A description of the Park is given. The distribution, habitat selection and food habits of each of the three species are discussed. The greatest interaction between these animals occurs through their effects on the range. Data, collected over the past years, on the incidence of brucellosis and its effect on the reproductive rate and health of the animals are presented. The high incidence of brucellosis in buffalo indicates that they are the source of the organism infecting moose and elk. Buffalo were found to be dominant over moose and elk. The effects of the existing dominance relations could not be evaluated. / Science, Faculty of / Zoology, Department of / Graduate

A study of the dispersion patterns of moose in winter habitats was conducted from June 1972 to May 1974 in a wildlife reserve in northeastern British Columbia. Major factors affecting the patterns were examined in an attempt to determine their relative importance. Data from eight representative vegetation plots indicated productive browse in deciduous forests and open habitats. In coniferous forest there was very little shrub development. Moose were well adapted to low winter temperatures which often followed warm winter temperatures associated with Chinook winds. Snow cover rarely exceeded 76 cm. Canopies of mature coniferous forest profoundly influenced the depth of snow on the ground, but, because the snow depth in open areas was not restrictive, moose did not extensively use coniferous forest. Willow, aspen and bog birch were the most important forage species. Rumen analyses and trailing methods supported these observations. Instances of moose cratering (pawing) and debarking were observed. Winter forages (probably a limited sample) were very low in crude protein. Open shrubland, agricultural land, and deciduous forest were preferred winter habitat. Several variables, quantified during ground and aerial observations, were used in a model to predict moose dispersion, but the model was applied with limited success. Future management of habitat for moose should include logging and prescribed burning to enhance the forage resource. The purchase of alienated lands to ensure control of the land base is also recommended. / Land and Food Systems, Faculty of / Graduate

The moose population in Sweden is one of the highest in the world. The population have positive impacts on humans but also cause problems such as browsing damages and collisions with traffic. To manage this population in an adaptive and ecological sound way, the managers need to have as much information as possible. The aim of this study was to improve the description of Sweden’s moose management areas regarding available forage for moose. This is done by describing the heterogeneity of the landscape within the moose management areas, which is done by using different landscape indexes. The heterogeneity indexes is then used to analyze if correlation exists between the variation of the landscape and firstly data that describes the available food, secondly data that indicates the moose population density. Multiple regression analysis were done in order to find a model with the indexes that best explains the variation in available forage and moose population indicators.  The results in this study showed a positive correlation between number of moose shot per 1000 hectares and patch richness awhile a negative correlation was found between number of moose shot per 1000 hectares and edge density. Results also showed a negative correlation between both edge density and the patch richness in the landscape with the presence of rowan, sallow, aspen and oak (RASE). Further developments of indexes that describe landscape heterogeneity is needed, but this study may indicate that knowledge of the variation in the landscape might provide useful information on the prerequisites for the Swedish moose population.
