Lane, Stan Boutin Published in Journal of Animal Ecology EXECUTIVE SUMMARY These data can be used to generate any results shown in this manuscript, especially Figures 1, 2, and 4. CONTACT Any questions should be addressed to Ben Dantzer (dantzer@umich.edu) NOTES ON COLUMN HEADERS OF CSV FILE “year” is the year of study (1 row per year per study grid) “Grid” is the name of the study area “# of squirrels” is the number of squirrels owning a primary midden in the spring (May) of that year on that study grid “Area (hectares)” - is the amount of area (in hectares) where we counted the squirrels in May “Squirrel Density (squirrels/hectare)” - is the “# of squirrels” divided by the “Area (hectares)” “Treatment” - Study grid treatment, either “control” for unmanipulated study areas or “food-add” for those grids where supplemental food was added “Number of Trees Counted” - total number of white spruce trees on that study grid in that year where we counted the number of cones “Current year Avg number of cones on trees” - average number of cones counted on those spruce trees “Current Year Cone Index (ln scale)” - index of production of spruce cones (see paper) in that year “Previous Year Cone Index (ln scale)” - index of production of spruce cones (see paper) in the previous year “Mast Year?” - was this year a white spruce one mast year or not? Lynx, Coyote, Marten (Pine marten), Weasel snow tracks are all the number of snowtracks counted by the Kluane Community Ecological Monitoring Program (see publication) in that winter, Note that Mustelild snowtracks is marten and weasel snowtracks combined.
