“…[10]. Because Ishikawa et al [9] suggest that mating success in this species is achieved only when females are nearly as heavy as males or lighter, the large kinky-coat males in the BAN strain were crossed to the small curly-hair females in the Tr strain. The F, hybrids produced from this cross were backcrossed to the kinky-coat shrews.…”

“…It is difficult to relate these morphological differences to fitness differences. In the musk shrew, Suncus murinus, ISHIKAWA et al (1991ISHIKAWA et al ( , 1995 suggested that individuals of different body size are less likely to mate successfully than individuals of similar body size. In S. araneus, HANSKI et al (1991) demonstrated that dispersers had longer tibia and hindfoot than residents.…”

Morphometrical Characteristics of the Common Shrews (Sorex Araneus L.) from Interracial Hybrid Zones

Common shrews are subdivided into numerous chromosome races which make contact and form hybrid zones. To date, no strong differences in morphology have been found between hybrid and pure race individuals from the vicinity of such hybrid zones. To investigate this further, we carried out studies in Poland on three hybrid zones between races belonging to the West and East European Karyotypic Groups using material collected from 1989 to 1994. Shrews were measured (head and body, tail and hindfoot length) and weighed. Statistically significant differences in morphology were only observed in the Stobnica/Legucki Mlyn hybrid zone. The results indicated that both adult and immature animals belonging to the Stobnica race were smaller than those belonging to the Legucki Miyn race. The hybrids were longer than individuals of pure race karyotype but the mean body mass of the hybrids was the lowest. At the population level, the size of the shrews varied with value of a hybrid index. The absence of similar results for the Drużnol/Łȩgucki Mtyn and Drnholec/Bialowieza hybrid zones may reflect their narrowness compared with the Stobnica/Łȩgucki Mlyn zone.

“…Eight male and 8 female F1 hybrids were produced as a result of 6 out of a total of 11 mating trials between 6 BAN males and 8 NAG females. Details of the interbreeding experiments have been described elsewhere [14].…”

“…No hybrid progeny of small NAG males and large BAN females, however, have been produced, and the cause is believed to be the difference in body weight between the sexes paired [14].…”
