Figure 1. Intensity (%) of decrease in braincase height and
body mass in different populations of common shrew across Europe.
Figure 2. Seasonal variation in braincase height in the four
populations analyzed in detail.
Figure 3. Seasonal variation in body mass in the four
populations analyzed in detail.
Figure 4. Seasonal variation in corrected brain mass in Gugny
and Radolfzell with fitted Generalized Additive Model, using jday as
smooth term (s), k=5. Solid line and shaded area represent fitted values
and
standard error of the model, respectively (e.d.f.=3.67, F(s)=14,
P(s)<0.001, deviance explained=38.4%). This fitted model
helps to illustrate how adult Gugny brains were collected before the
second size peak.
Figure 5. Variation between seasons and sexes in corrected
volume of brain regions in Radolfzell (blue) and Gugny (red). As in
Fig.4, the too early collection of adult brains in Gugny is evident.
