High mating success of low rank males in Limia perugiae (Pisces: Poeciliidae) as determined by DNA-fingerprinting Hierarchical structures among male individuals in a population are frequently reflected in differences in aggressive and reproductive behaviour and access to the females. In general social dominance requires large investments which in turn may have to be compensated for by high reproductive success. However, this hypothesis has so far only been sufficiently tested in small mating groups due to the difficulties of determining paternity by classical methods using non-molecular markers. DNA fingerprinting overcomes these problems offering the possibility to determine genetic relationships and mating patterns within larger groups. Using this approach we have recently shown (Schartl et al., 1993) that in the poeciliid fish Limia perugiae in small mating groups the dominant male has 100% mating success, while in larger groups its contribution to the offspring unexpectedly drops to zero. The reproductive failure under such social conditions is explained by the inability of the ex-male to protect all the females simultaneously against mating attempts of his numerous subordinate competitors. 1993 urn:nbn:de:bvb:20-opus-87132 Theodor-Boveri-Institut für Biowissenschaften OPUS4-6990 Wissenschaftlicher Artikel Schartl, A.; Schartl, Manfred; Anders, F.
