摘要: The habitat selection criteria of moose Alces alces at several scales are the basic sets information needed in management planning. We studied use central Finland during 1993-1996 using data from radio collared moose, satellite image based forest and land cover data, applied principles compositional analysis. compositions 54 home ranges (10 males summer, six winter, 23 females summer 15 winter) were first compared with overall landscape. around locations within their then composition range. Seasons sexes both scales. In there was only a slight difference between Based on tree species composition, located slightly more fertile areas than Within ranges, favoured non-pine dominated habitats mature forests, avoided human settlements. included significantly pine-dominated plantations other young successional stages role peatland forests/shrub especially pronounced winter. Winter less agricultural settlements landscape, probably due to distant location important winter man-made landscapes. used more, forests expected. At range scale, no statistical differences respect either season. different seasons, suggesting spatially segregated by individual sexes. is clear when tend pine-dominated, females.
