The Evolution od Diploid-polyploid Complex of Gibel Carp (Carassius gibelio): The Role of Parasites and Different Investment in Physiological Traits
Popis výsledku v původním jazyce
Carassius gibelio is a unique fish species in which two kinds of reproduction are known i.e. gynogenesis and gonochoristic reproduction. The former populations of this invasive species entered in the rivers of Czech Republic about 1975 and were composedof triploid females with gynogenetic reproduction. Recently, the coexistence of gynogenetic form (mainly triploid females, but occasionally also triploid males and tetraploid specimens have been identified) and gonochoristic diploid form have been reported. In this study the potential effect of parasitism on the evolution of diploid-polyploid complex of C. gibelio was analyzed. In addition, the selected measures of immunity and physiology were analyzed. We hypothesized that some traits in gynogens are weakened in order to compensate the two fold cost of reproduction in sexual form. All specimens were determined using morphological traits and mtDNA (D-loop).
