1. Most studies of intraspecific variation in home range size have investigated only a single or a few factors and often at one specific scale. However, considering multiple spatial and temporal scales when defining a home range is important as mechanisms that affect variation in home range size may differ depending on the scale under investigation. 2.

Within ungulate home ranges, suitable calving areas are of crucial importance for maintaining the reproductive potential of populations. Using GPS telemetry from a unique time series spanning before, during and after the construction of a 420-kV power line, we present results on calving site locations and area use during calving for two wild reindeer(More)
Most cervid populations in Europe and North America are managed through selective harvesting, often with age- and sex-specific quotas, with a large influence on the population growth rate. Less well understood is how prevailing weather affects harvesting selectivity and off-take indirectly through changes in individual animal and hunter behavior. The(More)
Harvesting by humans is the primary mechanism in regulation of many ungulate populations. Many harvested ungulate populations are migratory and fall migration often overlaps with hunting season. A main challenge in such systems is that ungulates often inflict damage on farmland and forest in the summer ranges, but that they migrate from these areas before(More)
