Available in PDF, EPUB and Kindle. Book excerpt: Outside Russia very little is known about the terrestrial ecology, vegetation, biogeographical patterns, and biodiversity of the enormously extensive ecosystems of Yakutia, Siberia. These systems are very special in that they function on top of huge layers of permafrost and are exposed to very severe and extreme weather conditions, the range between winter and summer temperatures being more than 100 degrees C. The soils are generally poor, and human use of the vegetation is usually extensive. Main vegetation zones are taiga and tundra, but Yakutia also supports a special land and vegetation form, caused by permafrost, the alas: more or less extensive grasslands around roundish lakes in taiga. All these vegetation types will be described and their ecology and ecophysiological characteristics will be dealt with. Because of the size of Yakutia, covering several climatic zones, and its extreme position on ecological gradients, Yakutia contains very interesting biogeographical patterns, which also will be described. Our analyses are drawn from many years of research in Yakutia and from a vast body of ecological and other literature in Russian publications and in unpublished local reports. The anthropogenic influence on the ecosystems will be dealt with. This includes the main activities of human interference with nature: forestry, extensive reindeer herding, cattle and horse grazing, etc. Also fire and other prominent ecological factors are dealt with. A very important point is also the very high degree of naturalness that is still extant in Yakutia’s main vegetation zones.
Download or read book Biological Systematics written by Alessandro Minelli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: To some potential readers of this book the description of Biological System atics as an art may seem outdated and frankly wrong. For most people art is subjective and unconstrained by universal laws. While one picture, play or poem may be internally consistent comparison between different art products is meaningless except by way of the individual artists. On the other hand modern Biological Systematics - particularly phenetics and cladistics - is offered as objective and ultimately governed by universal laws. This implies that classifications of different groups of organisms, being the products of systematics, should be comparable irrespective of authorship. Throughout this book Minelli justifies his title by developing the theme that biological classifications are, in fact, very unequal in their expressions of the pattern and processes of the natural world. Specialists are imbibed with their own groups and tend to establish a consensus of what constitutes a species or a genus, or whether it should be desirable to recognize sub species, cultivars etc. Ornithologists freely recognize subspecies and rarely do bird genera contain more than 10 species. On the other hand some coleopterists and botanists work with genera with over 1500 species. This asymmetry may reflect a biological reality; it may express a working practicality, or simply an historical artefact (older erected genera often contain more species). Rarely are these phenomena questioned.
