    Sammanfattning : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.

    Sammanfattning : Different plants have played an important role historically in the subsistence of the native Sami people of northern Fennoscandia. Generally, their use of plants have however been regarded as less vital in their overall subsistence and in comparison to the domesticated reindeer and the hunted game and fish. LÄS MER

  7. 5. Establishment and spread of non-native bark- and wood-boring beetles
