Downstream transport and seasonal variation in freshwater pearl mussel (Margaritifera margaritifera) eDNA concentration
Wacker, Sebastian; Fossøy, Frode; Larsen, Bjørn Mejdell; Brandsegg, Hege; Sivertsgård, Rolf; Karlsson, Sten (Peer reviewed, 2019)Environmental DNA (eDNA) can be used to detect the presence and abundance of aquatic organisms from water samples. Before implementing this methodology as a tool for monitoring, more knowledge is needed on variation in ... -

High levels of multiple paternity in a spermcast mating
Wacker, Sebastian; Larsen, Bjørn Mejdell; Jakobsen, Per; Karlsson, Sten (Journal article, 2018)Multiple paternity is an important characteristic of the genetic mating system and common across a wide range of taxa. Multiple paternity can increase within-population genotypic diversity, allowing selection to act on ... -
Host specificity drives genetic structure in a freshwater mussel
Wacker, Sebastian; Larsen, Bjørn Mejdell; Karlsson, Sten; Hindar, Kjetil (Journal article, 2019)Parasites often depend on their hosts for long distance transport, and genetic population structure can be strongly affected by host specificity and dispersal. Freshwater pearl mussel (Margaritifera margaritifera) populations ... -
Multiple paternity promotes genetic diversity in captive breeding of a freshwater mussel
Wacker, Sebastian; Larsen, Bjørn Mejdell; Jakobsen, Per Johan; Karlsson, Sten (Journal article; Peer reviewed, 2019)Captive breeding can be an important supplement to habitat restoration in the Conservation of threatened species. Careful choice of breeding regimes and genetic monitoring are essential to maintain genetic integrity and ... -
