Weaknesses of the method applied by Irwin et al. (1). (A) Only considering the temperature range used in the study (dashed gray lines) will lead to biased estimates of shifts in thermal niches. The difference between initial niche center (green) and shifted niche center (red) will be estimated too narrowly. (B) The signal-to-noise ratio in the training data for MaxEnt is low. MaxEnt estimates are based on the difference between background temperatures (black) and temperatures at presence locations (blue), which are small for broad thermal niches (red). Because temperatures at presence locations were estimated, at least in part, based on few observations, niche center estimates may have a low precision.
