Das atlantische Element in der Lebermoosflora Europas
- Eighty-five species of liverworts can be attributed to the atlantic element in Europe. These are grouped into tropical species, macaronesian species and species which reach to a different extend from the Macaronesian Islands to the Iberian Peninsula, Brittany, England and Ireland, Scotland, SW-Norway and the Faeroers as well as species which extend to the mountains of Central Europe, and species disjunct with the Himalayas or the east coast of North America. Since many of these species are called as relict species, the origin of these species is discussed and the arguments for and against relicts/long distance dispersal are enumerated. There are many arguments for a relict status but also for long distance dispersal. It can therefore be concluded that both cases are realized in different species.
