Dette stiller store krav til vore tr\u00e6arters tilpasningsevne.<\/p>\n
Feltfors\u00f8g anlagt i 1941 har vist, at \u00e6delgran (Abies alba) af syditaliensk (calabrisk) oprindelse udviser en ekstraordin\u00e6r vitalitet og tilpasningsevne, n\u00e5r den dyrkes udenfor sin hjemegn herunder i Danmark. Tidlige unders\u00f8gelser tyder p\u00e5, at \u00e6delgranen fra dette syditalienske omr\u00e5de har en langt st\u00f8rre genetisk variation sammenholdt med \u00e6delgran fra den \u00f8vrige del af artens udbredelsesomr\u00e5de. Dette er blevet forklaret ved, at \u00e6delgranen fra denne sydligste del af udbredelsesomr\u00e5det har bibeholdt en langt st\u00f8rre genetisk variation gennem de sidste par millioner \u00e5rs skiftende istider og varmeperioder sammenlignet med populationer fra mere nordligere breddegrader.<\/p>\n
Det foreliggende projekt s\u00f8ger via studier af DNA-mark\u00f8rer p\u00e5 udvalgte populationer af \u00e6delgran (i og udenfor Calabrien) at teste hypotesen om st\u00f8rre genetisk diversitet blandt calabriske fr\u00f8kilder. Desuden gennemf\u00f8res lignende unders\u00f8gelser af en r\u00e6kke andre tr\u00e6arter \u2013 herunder b\u00f8g og r\u00f8del, for at unders\u00f8ge om andre tr\u00e6arter udviser lignende karakteristika i Calabrien.<\/p>\n
Udover at f\u00e5 ny indsigt i istidernes indflydelse p\u00e5 vore skovtr\u00e6ers genetik og udvikling er det mere praksisorienterede form\u00e5l med studierne at kunne vurdere muligheden af at indf\u00f8re materiale fra disse omr\u00e5der for herved at \u201dhj\u00e6lpe\u201d vore hjemlige populationer til st\u00f8rre tilpasningsevne.<\/p>\n
