Will photoperiod requirements serve as a barrier to establishment of Ambrosia artemisiifolia in Sweden?

Our main hypothesis is that diversity among and within populations regarding the requirement of a specific photoperiod for induction of flowering enables an adaptation of Ambrosia artemisiifolia to northern latitudes. To test this hypothesis, a parallel common garden experiment including twelve populations is presently being conducted, at the same time, in Uppsala (Sweden) and in Osijek (Croatia). These populations originating from five European and two North American countries will be the base of one larger population genetic study using AFLP and microsatellites to trace-back the Swedish and European ragweed invasion.
