AbstractGaining accurate population information is crucial for the conservation and management of species. The National Monitoring Program for Large Carnivores monitors the Swedish lynx population (species Lynx lynx) by surveying family groups, non-invasive sampling and genetic analysis. Ten microsatellite regions were used as genetic markers to retrieve unique individual genotypes, through polymerase chain reactions (PCR) with specific primer-pairs and capillary-electrophoresis. Complete genotypes were matched using an internal database. The aim of this degree project was to show how monitoring of lynx through genetic analysis is carried out at the Department of Evolutionary Biology at Uppsala University, and to evaluate how effective these methods are and how they might be improved.Even though most of the methods used were fairly robust and reproducible, non-invasive sampling and microsatellite analysis posed some problems regarding DNA quality and quantity, and increased the risks of certain genotyping errors. These risks might be worth taking though, as gene...
