Morphology and coexistence of congeneric ectoparasite species:reinforcement of reproductive isolation?

Original language description

Several hypotheses to explain morphological differences among congeneric parasite species were tested, assuming that differences or similarities in morphology among congeners living in the same habitat are not a random pattern. These hypotheses were (1)reproductive isolation, (2) niche restriction due to competition, and (3) niche specialisation. Congeneric monogenean (platyhelminth) ectoparasites parasitising the gills of one host species were used as an ecological model. Morphometric distances of theattachment organ and morphometric distances of the copulatory organ between species pairs were used. Levins niche size and Renkonen niche overlap indices were calculated. Our results support the prediction that niche segregation has the function to achieve reproductive isolation of related species in order to prevent hybridisation (reinforcement of reproductive barriers). Parasite species living in the same niche greatly differ in the size of the copulatory organ. Moreover, species coex
