Download or read book Holoparasitic Orobanchaceae Cistanche Diphelypaea Orobanche Phelipanche in Armenia written by Renata Piwowarczyk and published by . This book was released on 2019 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The species of holoparasitic genera from the family Orobanchaceae have a specific lifestyle associated with the host, greatly reduced vegetative organs, very variable features and quickly lose their color, resulting in difficulties and mistakes in identification. This study represents the first comprehensive monograph of 36 species from the four holoparasitic genera, Cistanche, Diphelypaea, Phelipanche and Orobanche (Orobanchaceae), in Armenia. This country, as a part of the Caucasus, is one of the most important biodiversity centers in the world, a diversity which includes rich and insufficiently understood holoparasitic plants. Our investigations were based on five years of field work in the Caucasus, and complemented by examination of ca. 1200 herbarium sheets with ca. 3000 specimens from 37 herbaria. Key words: Caucasus, western Asia, parasitic plants, taxonomy, typification, new synonyms, new records, conservation assessment."--Page 3.
Download or read book The Vegetation of Georgia South Caucasus written by George Nakhutsrishvili and published by Springer Science & Business Media. This book was released on 2012-08-23 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes richness and diversity of Georgia’s vegetation. Contrasting ecosystems coexist on the relatively small territory of the country and include semi-deserts in East Georgia, Colchic forests with almost sub-tropical climate in West Georgia and subnival plant communities in high mountains. West Georgia lacks xerophilous vegetation zone and mesophilous forest vegetation spreads from the sea level to subalpine zone. The Colchic refugium (West Georgia) ensured survival of the Tertiary’s mesophilous forest flora. Vertical profile of the vegetation is more complex in East Georgia with semi-desert, steppe and arid open forest zone. In South Georgia the montane zone represented by montane steppe is devoid of forests
Download or read book Historical Biogeography of the Caucasus written by David Tarkhnishvili and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Caucasus is a mountain region located at the edge of Europe and Asia, between the Black and Caspian seas. In spite of limited geography and mostly temperate climate, diversity of natural landscapes, plant and animal species, and cultivated plants is unusually high. For these reasons, the Caucasus has been included in the list of global biodiversity hotspots. Proportion of endemic species of higher plants and terrestrial vertebrates varies between 15-30% for individual groups according to different authors, with a vast majority of some taxonomic groups such as terrestrial snails exceeding 80%. There is a number of relict plants and animals, whose relatives are not found in the neighbouring parts of Eurasia, but in the distant regions throughout the northern Hemisphere. Simultaneously, the Caucasus is known as an area of early settlements of hominids and the area of ancient agriculture. High proportion of endemic and relict species is unusual for a continental, non-tropical region. The author describes the biodiversity of the Caucasus region, starting from the Mesozoic time and ending with the current situation, and tries to analyse the evolutionary factors that shaped this diversity.
Download or read book Parasitic flowering plants written by Henning Heide-Jørgensen and published by BRILL. This book was released on 2008-07-31 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic flowering plants are strikingly impressive and beautiful and hold many surprises of both general and scientific interest. Parasites also have great influence on the quality of human life when attacking crop plants. Some parasites have since early times appealed to our imagination and have been part of religious or folkloristic events and used as gifts to royalties. This beautifully illustrated book covers all parasitic families and most of the genera. It also discusses the establishment of the parasite, the structure and function of the nutrient absorption organ (haustorium), and how the parasites are pollinated and dispersed as well as their ecology, hosts, and evolution. The book is written in a mostly non-technical language and is provided with a glossary and explanatory boxes. For additional information about this book, including some sample photographs, as well as a list of corrections that have been incorporated in the 2011 reprint, please visit the author's web site. Parasitic Flowering Plants was nominated by The Council on Botanical and Horticultural Libraries for the 2010 Annual Award for a Significant Work in Botanical or Horticular Literature, in the category ‘Technical Interest’.

Download or read book Relict Species written by Jan Christian Habel and published by Springer Science & Business Media. This book was released on 2009-12-03 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.
Download or read book Biology and Wildlife of the Mediterranean Region written by Jacques Blondel and published by Oxford University Press, USA. This book was released on 1999 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mediterranean is an outstanding 'hot-spot' of biological diversity. It is exceptional not only for this, but also because of its long history of interactions between its human inhabitants and the other fauna and flora of the region. The cradle of many civilizations, the Mediterranean region has been host to humans for thousands of years. This book is the first to synthesise our current understanding of the ecology, biology, and geology of Mediterranean animals, birds, and plants, and their habitats. The authors focus on the unique historical determinants and spatial patterns of Mediterranean biodiversity. In particular, the dramatic impacts of long-term human activities on the region's landscapes, flora, and fauna, are considered. This fascinating story will be of interest to researchers and students in ecology, biology, conservation, and geography, as well as to naturalists, and ecotourists visiting this popular holiday region.
Download or read book Plant Diversity in the Central Great Caucasus A Quantitative Assessment written by George Nakhutsrishvili and published by Springer. This book was released on 2017-05-18 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first assessment of the high-elevation flora of the Central Caucasus with a community ecology emphasis. Following a geostatistical-climatological description of the region (in comparison to the European Alps), it describes the montane, alpine and nival plant assemblages on the basis of an ecological approach that combines moisture, soils and local habitat peculiarities. Highlights include the famous giant herb communities in treeless parts of the upper montane belt, the various facets of alpine turf, and the unique assemblages and settings in the nival region. Further chapters address potential niche conservation between the Caucasus and the Alps, as well as a compilation of plant species habitat preferences (indicator values) that applies to a concept developed for the Alps. Richly illustrated and featuring extensive quantitative data on species abundance, the book offers a unique guide to the plant species diversity of this prominent mountain range, and a valuable resource for comparative ecology and biodiversity assessments of warm temperate mountain systems.
Download or read book Ethnobotany of the Caucasus written by Manuela Simioni and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Caucasus MRW (online and print) Volume will cover this European Macroregion. The content will focus on the ethnobotany of wild plants in this Macroregion and it will be first developed as an online site and, later, when all of the planned topics have been covered for this specific volume, printed in a hard copy version. The online site will remain live and be available for updates (with new monographs [if not covered initially due to lack of research]). The content will be divided into sections covering countries (or groups of countries), based on plant diversity and not necessarily political or national boundaries. The Caucasus volume will have an Introduction (4,000-6,000 words); 50 200 plant monographs (10 to maximum 50 monographs per country) with each monograph having a length of ~1,500 words (with references), plus 2-4 photographs. To further define the content, the plant monographs will be divided into five major categories (food; medicine/cosmetic; veterinary; handicraft plants; and ritual/folkloric uses) and include notes. The number of the monographs in every category will be negotiated depending on the advances of the ethnobotanical research in each specific country, or group of countries. The main criteria for the inclusion of a given plant will be its cultural salience within a given country (assessed by the Volume Editor). References will be given at the end of the Introduction and each monograph..."--Publisher's website.
