A 2014 selection journal "Outstanding educational identify" An Atlas of the World's Conifers is the 1st ever atlas of all identified conifer species. it truly is according to locality info of ca. 37,000 amassed herbarium specimens held in clinical associations. in addition to delivering average distribution maps for every species, Farjon and Filer supply the reader complete perception into the biogeography, variety and conservation prestige of conifers on all continents, dispelling the commonly held view that they're basically a northern boreal plant staff. Conifer range is analysed and awarded with a taxonomic and geographic point of view. Distribution styles are interpreted utilizing the newest details on continental go with the flow, dispersal and phylogeny. the whole dataset assisting the Atlas might be consulted and established on-line. those info is additionally used for extra study and are a useful source for an individual engaged on conifer systematics, biogeography or conservation. An Atlas of the World's Conifers exhibits the identified distribution of all conifers together with an research in their biogeography, variety and conservation prestige. additionally to be had from Brill is Aljos Farjon's A guide of the World's Conifers, released in 2010 (ISBN 978 ninety 04 17718 5).

We count these as natural occurrences (see photograph on p. 162). g. the SW USA and W-central Asia, junipers are dominant or co-dominant trees or large shrubs in open, semi-arid woodlands which can cover very large areas. g. in the Sierra Nevada of California, in the Taurus Mountains of Turkey, in the highlands of Ethiopia and Kenya, and in SE Xizang [Tibet] and E Qinjiang in China. In some regions, these forests were cut long ago, as in N-central China, but many juniper species are pioneer trees invading secondary, open woodland and abandoned grazing lands.
These two genera are largely responsible for the wide distributions of Cupressaceae and Podocarpaceae, including their occurrence on oceanic islands. In Pinaceae, the genus Pinus has been similarly successful even though only a few of its species are bird dispersed. With continuous or near continuous landmasses long distance dispersal is often not a necessary condition for wide distribution, as long as suitable habitat is widely available. e. , 2012). By this time the modern continents were not only formed, but had largely reached their present positions on the globe.
2012), with a common result that A. bracteata, a morphologically aberrant species from California, is sister to the rest of the genus. g. the species of Europe, Mediterranean, Turkey and Caucasus, but most are a mix of Asian and North American species, perhaps to be interpreted as the result of several migrations and subsequent radiations. A complex of species certainly occurs in the Sino-Himalayan region, where morphological polymorphism has given rise to divergent species concepts among taxonomists.
