Download or read book Meddelelser Om Gronland written by Bent Fredskild and published by Museum Tusculanum Press. This book was released on 1996-12 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytogeographically and climatically West Greenland includes parts of the low arctic and high arctic areas. The present vegetation and a summary of its history since the last glaciation based on pollen and macrofossil analyses are briefly described. The determination of more than 55,000 herbarium sheets of native phanerogams has been checked. Before preparing the dot maps it was necessary to decide at which level taxonomically difficult genera (eg: Antennaria, Draba, Poa, Puccinellia, and Stellaria would be treated). For all of these the criteria used are given. Dot maps have been prepared for 379 taxa. These maps have been grouped into 11 West Greenland distribution types, which clearly correlate with T W Böcher's biological distribution types (Böcher 1963). The collecting intensity in the large area is rather uneven. This is illustrated by a map giving the number of collections at the 305 localities from which 50 or more collections are at hand. Another map giving the number of taxa at 29 well-investigated localities illustrates the species diversity in the region. Most low arctic localities have more than 130 taxa, with 215 at the richest locality (Godhavn / Qeqertarsuaq on Disko), while the number at no high arctic locality exceeds lS0. Reference to the corresponding numbers in other parts of Greenland is given. Based on the dot maps a new delimitation of West Greenland in floristic provinces and districts is presented. It differs somewhat from that in Grønlands Flora / The Flora of Greenland (Böcher et al. 1957, and later editions). The major alteration is that the boundary between the low and high arctic phytogeographic provinces is now placed through north Disko - Nuussuaq. As a consequence of this the southernmost district in the high arctic is divided into an outer (NWso) and an inner province (NWsi). Minor alterations are suggested in the southern part of West Greenland.
Download or read book The Greenland Entomofauna written by Jens Böcher and published by BRILL. This book was released on 2015-05-26 with total page 897 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the ≈1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range shifts of the principal components of this biota a matter of some urgency.

Download or read book Flora of North America Volume 7 Magnoliophyta Dilleniidae Part 2 written by Flora of North America Editorial Committee and published by Oxford University Press. This book was released on 1993 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flora of North America Volume 7 will be the eighth of 19 volumes on dicotyledons to be published in the Flora of North America North of Mexico series. It treats 923 species classified among 125 genera in 11 families; the larger families covered in Volume 7 include Brassicaceae (Mustard family), Cleomaceae (Spiderflower family), and Salicaceae (Willow family). The endemic family Limnanthaceae with eight species classified in two genera (Floerkea and Limnanthes) is also included in the volume. Each genus has representative species illustrated with a line drawing that, in combination with keys and descriptions, will facilitate identifications of these groups of plants. Some of the genera treated in this volume with the most species in the flora area include: Boechera, Cardamine, Draba, Lepidium, Physaria, and Streptanthus (Brassicaceae) with 109, 39, 121, 42, 88, and 35 species, respectively; plus Salix and Populus (Salicaceae) with 113 and 8 species, respectively. Three families are represented in the flora each with a single introduced species: Caricaceae (Papaya family), Moringaceae (Drumstick tree family), and Tropaeolaceae (Nasturtium family).

Download or read book Flora of North America North of Mexico written by Flora of North America Editorial Committee, and published by OUP USA. This book was released on 2006-04-06 with total page 952 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flora of North America brings together for the first time ever in a concise and easy to understand format information on all of the plants growing spontaneously in North America north of Mexico. Volume 24 of Flora North America is one of two volumes on grasses to be published in this series (Volume 25, though it follows sequentially, was published in 2003). Together they will provide a comprehensive, authoritative, illustrated account of this important group of plants. Most of the species treated are either native to North America north of Mexico or are introduced species that are now established in the region, but there are many that do not fit into these categories. Among the additional species are several that the USDA has identified as major weed threats; and others that are known only as cultivated plants, some being cultivated for their ornamental value, others as sources for human food or animal forage. For instance, volume 24 includes such ecologically important genera as Elymus (wheatgrasses), Poa (bluegrasses), and Festuca (fescues), economically important species such as Triticum (wheat), Hordeum (barley), Oryza (rice), and Zizania (wild rice), several ornamental species, including some bamboos, and noxious weeds such as Elymus repens (quackgrass), and Bromus tectorum (cheatgrass). The volume includes identification keys, descriptions, line drawings, and ecological characteristics for each of the species; distribution maps for the native and established species; and a list of commonly encountered synonyms for the accepted names. The treatments, each of which has been extensively reviewed, are based on a combination of original observations and critical review of the literature.
