“…Home-range size using the buffered HR estimates was greatest during the Summer and smallest during the Winter, consistent with other literature Okarma 1988, McCulley 2015). Our MCP estimates of HRs were consistent with the seasonal HR sizes documented elsewhere in western Canada(Lemke 1998, McCulley 2015, being greatest during the Winter and smallest during Cavling. The difference between these HR estimates is likely due to individual daily movements.…”

“…McCulley et al (2017) reported that female moose had the smallest home ranges (100% MCP) during the Summer, 72 ±15 (SE) km 2 , and the largest during Early Winter, 172 ±34 (SE) km 2 . Lemke (1998) also noted that by using 100% MCP home-range estimators, female moose home ranges were smallest during the Summer and largest during the Winter (8.6 and 29.5 km 2 , respectively), regardless of moose travelling the furthest distance daily during the Summer (Lemke 1998, McCulley 2015.…”

“…We predicted that HR size would be positively related to daily movement distance as seen for moose in northern BC (Gillingham and Parker 2008b). We expected that daily movement rates and HR size of female moose would be largest during the Summer when movement is least restricted and smallest during the Winter due to increased snow depths that restrict movements (Cederlund and Okarma 1988, Lemke 1998, McCulley 2015, thereby reducing energetic expenditures (Parker et al 1984) when food quality is poorest (Moen et al 1997). We predicted that HR size would increase with the amount of salvage logging because of fragmentation of mature cover, increased browse searching time, and predator avoidance (Courtois et al 2002, Laurian et al 2008.…”

Moose are a keystone species and play a substantive role in predator-prey systems, nutrient cycling, and forest succession. Following a mountain pine beetle (MPB) spread across British Columbia, I quantified seasonal home-range selection, home-range size and daily movements, and within home-range selection of GPS-collared female moose in three study areas. I used case-matched logistic regressions with individual seasonal home ranges, and mixed-effects logistic regressions for seasonal locations of female moose to determine habitat selection at two spatial scales. Individual variation was evident at both home-range and within-home-range scales. Female moose selected lodgepole pine-leading stands at both spatial scales regardless of mass die-off due to MPB. Clear-cuts following the MPB outbreak were avoided in drier locations, and trade-offs between cover and browse were evident where disturbance due to salvage logging was highest. My findings indicate that MPB salvage-logging reduced moose habitat, and thereby, influenced selection by female moose.

The relationship between the attendance of artificial salt licks by European moose, Alces alces (Linnaeus, 1758), and biotic and economic-anthropogenic factors in the territory of the Leningrad Province was assessed. Data on the attendance of 19 mineral feeding sites obtained from automatic photo-video recorders (camera traps) were used in the analysis. Among the biotic factors that have a significant impact on attendance, the remoteness of the salt lick from the perennial water pool and the category of biotope according to the ground cover were revealed. Among the economic and anthropogenic factors – the remoteness of the salt lick from settlements with a population of more than 500 people. Similarly, the relationship between the sex-age structure of the registered moose flock with factors from the same categories was assessed. In addition, the effect of the recorded numbers of different sex-age groups on each other was assessed. A significant dependence of the registration of adult males on the area of wetlands and linear objects (power lines and gas pipelines) located within the boundaries of 1500 ha around the salt lick, as well as on remoteness from settlements, has been established. A significant dependence of the registration of yearling males on the area of wetlands around the salt lick and the number of registered adult males was established. A significant dependence of the number of registered adult females on the remoteness of the salt licks from a perennial water pool was noted. At the same time, the effect of any of the habitat groups on the recorded number of females has not been confirmed. Estimated population growth in sample areas depends on the sex ratio of registered individuals. The influence of limiting factors (predation, feed availability, hunting press) acting on moose populations in sample areas according to the methods used has not been revealed.

The paper presents the results of using neural networks of pixel-by-pixel image classification to decipher multichannel space images obtained by the Landsat 8 satellite. Natural habitats were identified based on differences in phytocenotic characteristics of land areas. The level of use of areas by elk was determined by the occurrence of elk presence indicators, which were the density of winter excrement piles (in spring) and the abundance of winged forms of the monoxenous ectoparasite of elk, Lipoptena cervi (Linnaeus, 1758), as measured by the number of individuals attacking the census taker (in the summer-autumn period). The material that forms the basis for deciphering was obtained by the route census method in different areas of the Leningrad Province. High values of the measured parameters were recorded in reforestation areas, in wet pine and birch forests, in aspen forests, on the edges of raised bogs and in overgrown fields – typical elk winter feeding habitats. Based on the data on the maximum values of the measured parameters, a positive correlation was established for the first time between the abundance of winged forms of L. cervi and the physiological activity of the host (the density of the piles of “winter” excrement). The paper also provides a valid reference to the material of schematic maps developed for a part of the territory of the Leningrad Province and Saint Petersburg. The scheme of the use of areas by elk is compiled on the basis of the relative index calculated from the measured parameters of the survey. Field observation areas and territories close to them were most reliably identified (90–95% accuracy). For areas not covered by field observations, the paper provides comments on the main inaccuracies of the schemes and the reasons for the identified discrepancies, based on an analysis of literary sources devoted to similar research topics. The results of the study indicate that the frequency of attacks of winged forms of L. cervi can be used as an additional criterion for assessing the stationary preferences of elk in the winter period using information on the period of active flight, and the decoding method mentioned in the paper can be used in limited areas of specific territories, including reserves, areas of hunting farms and district forestries.
