dc.description.abstractOne predicted impact of climate change is a poleward shift in the boundaries of species ranges. Existing methods for identifying such a boundary shift based on changes in the observed pattern of occupancy within a grid of cells are sensitive to changes in the overall rate of sightings and their latitudinal distribution that are unconnected to a boundary shift. A formal test for a boundary shift is described that allows for such changes. The test is applied to detect northward shifts in the northern boundary of the Essex skipper butterfly and the European goldfinch in Great Britain. A shift is detected in the latter case but not in the former. Results from a simulation study are presented showing that the test performs well.en_US
