“…Brown (1967) made crosses from the two parts of the disjunct range of Scaphiopus hammondi, a spade foot toad, and found no apparent incompatibility, even though the two populations, from California and Arizona, showed significant differences in their rates of embryonic development. There was no indication of incompatibility in crosses and backcrosses of populations of the field mouse A podemus sylvaticus from the islands of St. Kilda, South Uist, Skomer, Bardsey, and from Ireland with English stock (Jewell and Fullagar, 1965), nor has any F 1 hybrid infertility been found in intraspecific crosses involving a total of twenty-three races of six species of Peromyscus (Dice, 1933).…”

“…Apodemus flavicollis and A. sylvaticus are closely related species, and indeed were at one time classified as subspecies. However, they do not interbreed, either in the wild or under laboratory conditions (Jewell & Fullagar, 1965). The discrimination factor of just over 10% observed in reciprocal incubation experiments may be compared with the factor of 30 % which we obtained for the less closely related species, mouse and rat (McLaren & Walker, 1965).…”

“…Des travaux de Peshev et Georgiev (1961), en Bulgarie, et de Witte (1964) Lehmann, 1964). Larina (1961) a obtenu le croisement dans les conditions de laboratoire entre les deux especes, D'autres mammalogistes n'ont pu Fobserver (Zimmermann, 1957 ;Saint Girons, 1962 a ;Jewell et Fullagar, 1965 A la suite des travaux de Blair (1951) et Mayr (1963), Amtmann pour expliquer la formation d'hybrides met en cause la deforestation intensive de PEurope occidentale qui favorise la rupture des mecanismes d'isolement entre les deux especes. Nous partageons entierement ce point de vue.…”
