Table 2 Observed elevational ranges of small mammals in the 1 Yosemite transect [5] compared with predictions from SDMs using climate, habitat, and climate + habitat predictors thresholded using the MSSS rule

From: The relative influence of change in habitat and climate on elevation range limits in small mammals in Yosemite National Park, California, U.S.A.

  1. Shaded cells under the SDM columns indicate predictions that agree with the observed range trend. Total no. agreement corresponds to the number of times the SDMs agreed with occupancy modelling. Values represent modern minus historic range values. E – expand, NS – no shift, C – contract, D – downward, U – upward, and NA – not applicable, i.e., when there was no convergence towards a model solution because the samples were all outside estimated range limits so no model was produced
