Alternative reproductive tactics increase effective population size and decrease inbreeding in wild Atlantic salmon
International audience While nonanadromous males (stream-resident and/or mature male parr) contribute to reproduction in anadromous salmonids, little is known about their impacts on key population genetic parameters. Here, we evaluated the contribution of Atlantic salmon mature male parr to the effe...

Moreover, mature male parr boosted the number of alleles found among progenies.

International audience While nonanadromous males (stream-resident and/or mature male parr) contribute to reproduction in anadromous salmonids, little is known about their impacts on key population genetic parameters.
