摘要："A taxonomic level, the genus, is analyzed from the perspective of reproduction isolation. It is concluded that if species are, by definition, reproductively isolated, then species in one genus should not be capable of breeding with species in other genera. A survey of reported mammalian intergeneric intergeneric hybrids and the application of reproductive criteria to the definition of the category of genus led to the recommendation of a number of taxonomic changes in the context of genera. These include the following genera, with synonyms in parentheses: Macropus (Thylogale, Osphranter, Megaleia, Wallabia); Cercopithecus (Papio, Macaca, Cercocebus, Mandrillus, Cynopithecus, Theropithecus, Erythrocebus, Allenopithecus, Comopithecus); Grampus (Steno, Tursiops); Canis (Alopex, Urocyon, Fennecus, Vulpes, Cerdocyon, Dusicyon); Ursus (Thalarctos, Selenarctos); Melursus (Helarctos); Felis (Panthera); Arctocephalus (Zalophus); Tayassu (Dicotyles); Cervus (Dama, Axis, Elaphurus); Bos (Bibos, Bison); Tragelaphus (Taurotragus, Boocercus); Cephalophus (Sylvicapra); Alcelaphu (Damaliscus, Beatragus); Connochaetes (Gorgon); Kobus (Adenota, Onotragus); Capra (Ovis, Ammotragus)"--P.
