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.
