These datasets contain movement data and coat colour data from accelerometer-collared hares collected during the autumns of 2015-2017 and springs of 2015-2018. We analyzed how coat colour mismatch affects snowshoe hare foraging time across these two seasons. For more details on how foraging behaviour was inferred from accelerometer data, see Studd et al. (2019). Other variables that influence snowshoe hare foraging time are also included in these datasets. Data were collected in the Kluane Lake region of the Yukon.

These datasets contain survival data for snowshoe hares collected in the springs of 2015-2018, between March 1 and May 31 and in the falls of 2015-2018, between September 1 and December 1. Survival data were obtained by conducting telemetry checks on VHF-collared hares. Various covariates of interest are included, such as weather metrics and coat colour mismatch values. We used these datasets to assess the influence of coat colour mismatch on snowshoe hare autumn and spring survival. These data were collected in the Kluane Lake region of the Yukon.

Lemmings construct nests of grass and moss under the snow during winter, and counting these nests in spring is 1 method of obtaining an index of winter density and habitat use. We counted winter nests after snow melt on fixed grids on 5 areas scattered across the Canadian Arctic and compared these nest counts to population density estimated by mark-recapture on the same areas in spring and during the previous autumn. Collared lemmings were a common species in most areas, some sites had an abundance of brown lemmings, and only 2 sites had tundra voles. Winter nest counts were correlated with lemming densities estimated in the following spring (r(s) = 0.80, P < 0.001), but less well correlated with densities the previous autumn (r(s) = 0.55, P < 0.001). Winter nest counts can be used to predict spring lemming densities with a log-log regression that explains 64% of the observed variation. Winter nest counts are best treated as an approximate index and should not be used when precise, quantitative lemming density estimates are required. Nest counts also can be used to provide general information about habitat-use in winter, predation rates by weasels, and the extent of winter breeding.
