Genetic Structure of a Rare European Conifer, Serbian Spruce (Picea Omorika (Panč.) Purk.) [link]Paper  doi  abstract   bibtex   
Genetic variation in 13 populations of a Balkan endemic, Serbian spruce ( Picea omorika (Panc ˇ .) Purk.), was investigated using 16 isozyme loci. Serbian spruce is characterized by low levels of genetic variation (average proportion of poly- morphic loci was 20.9\,% and average expected heterozygosity was 0.067). In most populations, a significant surplus of heterozygotes was observed, indicating a strong selection against inbreds. In the largest populations, fixation indices were positive, probably due to within-population differentiation and the associated Wahlund effect. Despite a strong overall differentiation ( F ST =0.261), no geographical trends in the genetic variation could be identified. Genetic drift caused by small effective population sizes and a strong fragmentation is the most plausible expla- nation for such variation patterns. A Bayesian analysis of population structure revealed the existence of two clusters, which are supposed to be possible remnants of ancient differentiation within a large range of the predecessor of Serbian spruce, Picea omoricoides Weber. Ex situ conser- vation measures, namely establishing seed orch- ards from trees of mixed origin, are proposed as a necessary complement to in situ protection of natural stands
