Ivlev’s electivity index (Manly et al. 2002, Cook et al. 2016) ranges from -1 to +1 and was calculated as: = − + I % Twigs Browsed % Twigs Available % Twigs Browsed % Twigs Availableij (2) for species i along transect j. Ivlev’s index is symmetric about 0, facilitating direct interpretation of moose selection or avoidance of species i.	cache/alces-275.pdf	txt/alces-275.txt
