Diploidit, suvullisesti lis\u00e4\u00e4ntyv\u00e4t muodot luokitellaan usein samaan lajiin kuuluviksi. Kun laji levisi Euroopassa, on havaittu lajin vahvoja vaikutuksia ekosyysteemeihin ja erityisesti sukunsa ainoaan eurooppalaiseen lajiin, ruutanaan.

As this group consists of sexual and asexual complexes with different ploidies it is very difficult to apply the traditional species concept. The polyploid gynogenetic forms have been mostly summarized under the synonym Carassius (auratus) gibelio, commonly known as Prussian or gibel carp. Diploid, sexual forms are often classified as conspecific. When invading European waters, Prussian carp had a strong impact on the ecosystems, but especially on the only European carassiid, the crucian carp. In a case study, the Prussian carp complex currently invading Finland was analyzed ecologically and genetically. In a breeding experiment the potential sexual hosts of asexual Prussian carp in Finland and their genetic interactions were assessed. All tested hosts were found to be suiting. The studied complex was found to be highly diverse and consisting of a sexual and a gynogenetic lineage that spread independently. The latter is capable of receiving introgressions from sexual hosts regardless of genus. The degree of genetic introgression into the complex remains unresolved, but there are enough hints to propose an evolutionary effective reproductive system of introgressive gynogenesis, which will explain the Prussian carp\u2019s extreme success. Based on the results and literature the invasive potential and threat to the European crucian carp was evaluated. It was found probable that gynogenetic Prussian carp will invade Southern Finland and eradicate crucian carp resulting in a high Finnish and Nordic responsibility for the conservation of European crucian carp in uninvaded areas.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Manuel Deinhardt (madeinha) on 2013-11-15 14:34:30.912944.
