Figure 5

Average mass (± 1 SE) of adult N. bryanti and N. lepida used in the mate choice trials (squares, males n = 33; circles, females n = 65) and from a broader sample (dashed lines linking thick bars). The broader sample included trial animals plus additional adults from sympatry (n = 451; Whitney Well, Figure 1) and allopatry (N. b., n = 6, from Alameda, Kern, and San Diego Counties; N. l., n = 86, from Inyo, Kern, Lassen, and San Bernadino Counties, Figure 1, inset). Neotoma bryanti were heavier than N. lepida, males were heavier than females, and mass increased in sympatry with a sharper increase in N. lepida (see Results for details).
