A birch is a thin-leaved deciduous hardwood tree of the genus Betula (/ˈbɛtjʊlə/),[2] in the family Betulaceae, which also includes alders, hazels, and hornbeams. Betula nana and tree Betula pollen grains were separated following Birks (1968) and Clegg et al. The genus Betula contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species.

Betula nana (dwarf birch) is one of the circumpolar Arctic shrubs that play a major role in the ‘greening of the Arctic’ and for which growth has been shown to react positively to both experimental summer warming Correspondence: Bo … In the High Arctic, physical environmental factors exceed (2005). Meadow vegetation is diverse and dominated by forbs, graminoids and sedges, while heath vegetation is less diverse and dominated by deciduous and evergreen dwarf-shrubs and Betula nana. chzerepanovii), and the tree line reaches the altitudes of 250 m a.s.l. Amidst the green, however, a second glance reveals numerous other plant species in a multitude of colours – grasses, forbs, lichens and mosses, bringing diversity to the sea of … The scientific name of resin birch is Betula glandulosa Michx.

Birch, any of about 40 species of short-lived ornamental and timber trees and shrubs constituting the genus Betula (family Betulaceae), distributed throughout cool regions of the Northern Hemisphere. Given the recently released genome of Betula nana [32], we used BLAT [33] to map our transcriptome assembly against this genome that currently consisted of 551,915 contigs. ADAPTATIONS OF ARCTIC AND ALPINE PLANTS 121 change in floristic composition of the vegetation in the seral stages leading to a stable community (Oosting 1948, Muller 1952). Birch belongs to the genus Betula and is grouped under the Betulaceae family.These are medium-sized plants which grow 40-50 feet tall. 3 ), suggesting that dispersal … Cuticle analysis performed on fossil Betula nana (L.) leaves provides a strong proxy to reconstruct past growing season thermal properties expressed as growing degree days (GDD 5). adaptations to strong disturbance, they are less than adequate and the hypothesis that arctic plants avoid, rather than adapt, ... tundra areas with Betula nana and ericaceous dwarf shrubs as dominant species. This proxy is so far available for the dwarf birch only and, therewith, restricted to regions or past periods of subarctic climatic conditions. Hybrids have been largely described between the three European birches, the diploid B. pendula and B. nana … exilis and Betula nana subsp.
