ABSTRACT:
Species
biological history revealed by genetic indicators can provide guidelines for
long-term biodiversity conservation in Natura 2000 network. Fagus sylvatica is the keystone species which regulates in the
Mediterranean Eco-Region ecosystem structure, function and composition. Six
hundred fifty nine F. sylvatica individuals have been sampled across 20 sites of European interest in Southern
Italy and analyzed at 5 microsatellite loci. For sites marked by both maximum
heterozygosity (Ho) and minimum
heterozygote deficit (Fis)
(IT9210210, ITA070099, IT9210205 and IT9220075) it is suggested to avoid
impacts by adopting very conservative measures. Promoting migration processes
(pollen flow and seed flow) would be appropriate where it has been monitored
low heterozygosity and high genetic disequilibrium. Margin effect due to
dryness should be buffered with appropriate belts of thermophilus broad leaved
tree species.
