    Reproductive barriers between congeneric monogenean parasites ( Dactylogyrus: Monogenea): attachment apparatus morphology or copulatory organ incompatibility?

  • Original language description

    Morphometrical parameters of the attachment apparatus and copulatory organs of 52 Dactylogyrus species parasitizing 17 species of cyprinid fishes were analysed to test for the existence of reproductive barriers among congeneric species. The minimal spanning tree (MST) method was applied in the analyses. The position of "real" parasite communities, based on (1) observed infracommunities, (2) a checklist of parasites for a given host in the morphological space, was compared to the position of randomly generated communities using all Dactylogyrus species. The distribution of species similarity within infracommunities (using both attachment and copulatory measurements) was not significantly different from that obtained by simulation, and this trend was similar for both the checklist and observed infracommunities. When real infracommunities were separated according to host specificity (specialists versus generalists), we found differences reflecting similarities in the shapes of attachment

    Reprodukčné bariéry medzi kongenerickými parazitmi (Dactylogyrus: Monogenea): morfológia prichycovacieho aparátu alebo inkompatibilita kopulačného orgánu?

  • Czech description

    Morfometrické parametre prichycovacieho aparátu a kopulačných orgánov u 52 druhov rodu Dactylogyrus parazitujúcich 17 druhov kaprovitých rýb boli analyzované a testovaná bola existencia reprodukčných bariér medzi kongenerickými druhmi. Metóda "minimal spanning tree (MST)" bola aplikovaná v analýzach. Pozícia "skutočných" parazitických spoločenstiev, založená na (1) pozorovaných infrakomunitách, (2)checkliste parazitov pre daný hostiteľský druh v morfologickom priestore, bola porovnávaná s pozíciou náhodne generovaných spoločenstiev použitím všetkých druhov rodu Dactylogyrus. Distribúcia druhovej podobnosti v infrakomunitách(použitím rozmerov oboch prichycovacieho aparátu a kopulačných orgánov) nebola štatisticky významne odlišná od simulovanej, a tentotrend bol podobný u oboch typov dat: checklist a pozorované infrakomunity. Po separovaní skutočných infrakomunít podľa hostiteľskej špecifickosti (špecialisti versus generalisti), boli zistené rozdiely odrážajúce podobnosť v tvare prichy
