“…Like other studies (Peek et al 1974;Barrette 1991;Vincent et al 1995), this work confirms that group size in deer is positively affected by population density. There remains the interesting question of the mechanism behind this relationship.…”

“…The several explanations for this relate to antipredator strategies (Estes 1974;Jarman 1974;Hirth 1977), ease of maintaining visual contact among group members (LaGory 1986), and food conditions (Borkowski and Furubayashi 1998a). Although a positive relationship between group size and population density is well documented in cervids (Peek et al 1974;Barrette 1991;Vincent et al 1995), information on the influence of density on group size in different habitats is limited to that in Thirgood (1996). If predators or visibility determine habitat differences in group size, then deer population density should affect this factor to a similar extent in different habitats.…”

The influence of population density of sika deer (Cervus nippon) on their activity, habitat use, and habitatrelated group size was studied in the area of Japan's Tanzawa Mountains in early winter. The percentage of active sika deer was higher in January 1994 (a low-density period) than in January 1995 (a high-density period). The pattern of habitat use differed between periods. During the high-density period, deer increased their relative use of lower quality habitats. A possible mechanism and implications of this are discussed. Changes in population density had a positive effect on group size in sika deer, though the variation among habitat types supported the hypothesis that food biomass is an important determinant of group size.

“…With high legs and a chest height of 80-105 cm, the moose is well-adapted to moving in snow, and movements are only severely restricted when snow depth exceeds 70-90 cm (Kelsall 1969). In deep snow cover periods, moose tend to aggregate and follow the same tracks probably to lower energy costs (Peek et al 1974). In addition to snow depth, the quality of snow in terms of density and hardness can also affect the trail-following behaviour of moose (Lundmark and Ball 2008).…”

To be presented, with the permission of the Faculty of Agriculture and Forestry of the University of Helsinki, for public critisism in auditorium 108 (ls B3), Metsätieteiden talo (Viikki campus, Latokartanonkaari 7, Helsinki) on March 24 th 2017, at 12 o´clock noon. ABSTRACTThe Moose is a valuable game animal in Fennoscandia but also the most severe pest in forest plantations. In this thesis, I examined factors that affect the habitat selection of moose and moose damage at multiple scales. At the plot level, browsing increased with an increasing number of artificially regenerated pines and deciduous trees taller than pines. The damage risk was the highest in plantations with heavy soil preparation.Moose summer home ranges had more fertile sites than the overall study area. Within summer ranges moose, selected non-pine-dominated habitats and mature forests and avoided human settlements. Winter ranges contained more pine-dominated plantations and other young successional stages, more pine dominated peatland forests and less human settlements and agricultural fields. Within winter ranges, moose used more non-pinedominated plantations and mature forests and less human-inhabited areas than expected. At the home range level, there were no significant differences between sexes, but within home ranges males and females used different habitats during both seasons.The occurrence of damage in nearby landscape decreased the probability to find a landscape without damage and predicted an increase in the number of damaged plantations. Increased food-cover adjacencies of mature forests and plantations increased damage. An increasing proportion of inhabited areas and the length of connecting roads decreased the number of damage at the landscape sizes of 1 km 2 and 5 km 2 . Moose-damaged stands were concentrated in SW and eastern Lapland in Peräpohja Schist Belt and Lapland's Greenstone Belt with nutrient-rich bedrock. There was less damage in landscapes with an abundant amount of pine-dominated thinning forests. Moose damage plantations were located more on fertile bedrock and soils than undamaged ones. Regenerating Scots pine on fine-grained soils derived from nutrient-rich rocks and naturally occupied by Norway spruce might increase damage risk.

“…Most moose populations are composed of sohtary individuals existing at low densities in boreal forests, where forage biomass is low (Geist 1963;Krefting 1974;LeResche et al 1974;Peek et al 1974). Forest fires result in a localized resurgence of shrubs and an abundance of high-quaUty forage.…”

Are Moose Mice? The Function of Scent Urination in Moose

Abstract.•Scent urination likely serves a variety of functions, depending on the species and environment in which it is expressed. Evidence derived from observations in Denali National Park and Preserve (DNPP) suggests that scent urination by bull moose {Alces alces) is primarily directed toward females and supports the hypothesis that scent urination induces ovulation in cows. Testing of this hypothesis should be possible in captive populations. Males also appear to use urine as a means of attracting females.
