Bryophyte community diversities and expected change under a warming climate in contrasting habitats of the Torngat Mountains, Labrador
In this study we provide the first record of bryophyte community diversities in contrasting habitats of the Torngat Mountains National Park (Labrador, Canada), a coastal mountain subarctic ITEX (International Tundra Experiment) study site. The point-intercept method was used to describe and track ch...

In this study we provide the first record of bryophyte community diversities in contrasting habitats of the Torngat Mountains National Park (Labrador, Canada), a coastal mountain subarctic ITEX (International Tundra Experiment) study site. The point-intercept method was used to describe and track changes in the bryophyte community diversity (cover, species richness, diversity indices) at dry vs. wet habitats, in 2008 and 2010. The majority of species observed are common and abundant to the Canadian polar region. Bryophyte community composition differed between wet and dry habitats; Racomitrium lanuginosum, Polytrichum piliferum and P. juniperinum dominated dry and exposed habitats, whereas Drepanocladus spp., Aulacomnium spp. and Sphagnum spp. dominated wet habitats.
