Download or read book Meddelelser Om Grønland 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 An Altitudinal Study of the Flora of the Inland Mountains of South-East Greenland written by Geoffrey Halliday and published by . This book was released on 2019-02 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prior to 1963 virtually all our knowledge of the flora of south-east Greenland had been gained at low altitudes. However, that year saw the first of seventeen European mountaineering expeditions to the region covered in this volume. Their members rarely had any botanical expertise, but the author was able to persuade most to make collections and record the altitude. This resulted in 111 collections from altitudes of up to 2480 m. This, in Schweizerland, is probably the highest altitude for vascular plants in the Arctic. The region was divided into northern and southern halves, 100 species being recorded from the southern area and 86 from the northern. The altitude range in each was divided into three zones, and the proportion of each of eleven biological distribution types (e.g., low Arctic, high Arctic) was determined for each zone. This showed a clear transition from mainly low-Arctic oceanic montane species in the lower zone to widespread Arctic montane species in the higher zone. Graphs are plotted showing the decrease in the number of species with altitude. When extrapolated, they suggest maximum limits of 2250 m in the south and 2400 m in the north. There is a close correlation between number of species and altitude, with the mean decrease being about two species per 100 m. Records of bryophytes and lichens are included as appendices.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding deserts and drylands is essential, as arid landscapes cover >40% of the Earth and are home to two billion people. Today's problematic environment–human interaction needs contemporary knowledge to address dryland complexity. Physical dimensions in arid zones—land systems, climate and hazards, ecology—are linked with social processes that directly impact drylands, such as land management, livelihoods, and development. The challenges require integrated research that identifies systemic drivers across global arid regions. Measurement and monitoring, field investigation, remote sensing, and data analysis are effective tools to investigate natural dynamics. Equally, inquiry into how policy and practice affect landscape sustainability is key to mitigating detrimental activity in deserts. Relations between socio-economic forces and degradation, agro-pastoral rangeland use, drought and disaster and resource extraction reflect land interactions. Contemporary themes of food security, conflict, and conservation are interlinked in arid environments. This book unifies desert science, arid environments, and dryland development. The chapters identify land dynamics, address system risks and delineate human functions through original research in arid zones. Mixed methodologies highlight the vital links between social and environmental science in global deserts. The book engages with today's topical themes and presents novel analyses of arid land systems and societies.
