Figure 1. Predicted hibernation duration, fat and body mass forMyotis lucifugus. Top left: Predicted hibernation duration
(days) across temperate North America for Myotis lucifugus . Top
right: Linear relationship between body fat and body mass. Each point
represents an individual bat and colours indicate the state of each
record (Montana = red, New York = green, Vermont = blue). Bottom left:
Predicted pre-hibernation body mass of M. lucifugus (g) across
the species’ distribution. Bottom right: Predicted pre-hibernation fat
resources (g) from the linear relationship between fat mass and body
mass. Numbers define changes in contours.
