Zur Frage der Introgression bei den Waldmäusen Apodemus sylvaticus und A. flavicollis (Mammalia, Rodentia)

Abstract: Zusammenfassung In einer Anzahl von Populationen am gemeinsamen sudlichen und westlichen Arealrand wird untcrsucht, ob dort die grode ühnlichkeit von Apodemus sylvaticus und A. flavicollis das Ergebnis zwischenartlicher Bastardierung oder gegenlaufiger, innerartlicher, geographischer Merkmalsanderung ist. Als in Freilandpopulationen erkennbare Bastarde werden Tiere angesehen, die unabhangige Merkmale beider Arten in sich vereinigen. Die eingehende Prufung der Merkmale ergab, dad vorlaufig nur zwei deutliche, u… Show more

“…Latitudinal body size changes have been set forth in five species of Apodemus in relation to Bergmann's rule or the reverse of Bergmann's rule. Apodemus flavicollis obeys Bergmann's rule (Niethammer 1969(Niethammer , 1978aAlcántara 1991), whereas three species of Apodemus follow the reverse of Bergmann's rule: A. sylvaticus (Niethammer 1969(Niethammer , 1978bAlcántara 1991;Renaud and Michaux 2007), A. chevrieri (Li et al 2008), and A. agrarius (Hille and Meinig 1996;Koh et al 1998). Apodemus mystacinus conforms to Bergmann's rule (Tchernov 1979) or the reverse of Bergmann's rule (Yom-Tov and Geffen 2006).…”

“…The term "character displacement" was originally given by Brown and Wilson (1956) as for competition between the two species, and later it was redefined by Grant (1972) as the process by which a morphological character state of a species changes under natural selection arising from the presence of one or more ecologically and/or reproductively similar species in the same environment. Bergmann's rule disclosed in A. flavicollis and the reverse of Bergmann's rule exhibited in A. sylvaticus were explained by character displacement (Niethammer 1969;Alcántara 1991), because their geographical ranges are overlapped in Europe (Corbet 1966;Panteleyev 1998).…”

“…Studies of seasonal changes in B chromosome frequencies Zima et al 1997). It should be noted that both species belong to the subgenus Sylvaemus Ognev and Vorobiev, 1923, they share the same habitats in most parts of their distribution, and even live sympatrically in some areas (Niethammer 1969). In some parts of their range (southeastern Europe) it is very difficult to make a morphological distinction between them as differences in morphological characters between populations of the same species are of the same magnitude as differences between species.…”
