Download or read book Lessepsian Migration written by F.D. Por and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are few achievements of modern man which can compare to the Suez Canal. In Egypt-the land of the most famous wonders of antiquity-the Suez Canal was built as the first technical wonder ofthe industrial revolution. Ferdinand de Lesseps was a man straddling two epochs-the romantic utopism of Saint Simon and the modern world of technocracy. The gigantic project was at its start shouldered by the crowds of tens of thousands of forced laborers still available and ended as a show-piece for modern mechanical earth-moving techniques. The canal builders themselves were still polyhistors in the old sense: engineers cum-zoologists; naval officers-cum-geologists; diplomats meddling with chem istry. During the four generations of the existence of the Suez Canal, the fateful professional narrowmindedness became progressively worse. The engineers con tinued their work in and around the Canal, but they became oblivious and unresponsive to the environmental impact, to the fascinating changes in the biotic scenery which they were producing with their own hands.
Download or read book Mediterranean Marine Ecosystems written by Maria Moraitou-Apostolopoulou and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the papers presented at a NATO Advanced Research Institute on "Mediterranean Marine Ecosystems", held at Heraklion-Crete, Greece, from September 23-27, 1983. A workshop rather than a conference, it was sponsored by the Eco-Sciences Special Programme Panel, in cooperation with the Marine Science Panel. The third of its kind, it was scheduled in the framework of a project on a multidisciplinary integrated approach to the study of the Mediterranean. This Sea and the surrounding land was not only the cradle of many civilizations but is, up to the present time, one of the major world areas of marine traffic, communication and exchanges, fisheries and aquacultures, inshore human activities and ••• pollu tion. To a certain degree it constitutes a gigantic natural labo ratory, where the fate of threatened aquatic and terrestrial eco systems including the human one, is tested. The Mediterranean Sea, with its geological history and present day geographic, hydrological and climatic conditions is believed to form an ecological entity. Important exchanges and mutual influences take place with the surrounding land area and the water masses, naturally (Atlantic, Black Sea) or artificially (Red Sea), connected to the Mediterranean. Therefore, a better and in-depth knowledge of the various ecosystems, benthic, planktonic and nektonic, neritic or pelagic, in the Western or the Eastern Basin seems to be a pre requisite to any action in preserving, upgrading and managing the natural resources of the area.

Download or read book The Legacy of Tethys written by F.D. Por and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an attempt to present a comprehensive view on the aquatic biogeog raphy of a small but very dynamic and complex area of the globe. Luckily, this area, called here the Levant, has attracted much interest in the past and is being increasingly studied in the present. The interphasing between the knowledge of the historical and formative processes and that of the recent distributional aspects is fairly good. The recent years saw also a widening effort which expressed itself in several symposia and monographic books. Therefore I considered it possible to treat the whole subject of the aquatic biogeography of the Levant singlehandedly rather than in the presently widespread manner of an edited book. I am keenly conscious of the shortcommings of my approach of presenting much second-hand information. Possibly this is being compensated by the fact that this book has a more coherent structure and eventually a clearer scientific message. The effort spent in synthesizing the data from the widely different sources hopefully pays off in a presentation which is more easily comprehended by the average reader. For the suspicious reader, I would recommend to read first the closing chapter of this book in which the quintescence of this book and its message is presented in a summariz ing manner.
Download or read book Biodiversity Enrichment in a Diverse World written by Gbolagade Akeem Lameed and published by BoD – Books on Demand. This book was released on 2012-08-29 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book - Biodiversity Enrichment in a Diverse World - considered biodiversity (plants, animals, fungi, and microbes) from three different angles: genetics, species, and ecosystems. The relationships between them are complex and it looks at these aspects from different angles and also various interventions at different levels. The scientific approach of the book demonstrates that the three levels are closely inter-connected and action is therefore needed to conserve and protect the systems if the benefits provided to human life will continue to be available. However, conservation of the biological diversity is essentially an umbrella term for traditional species, relationship to human health, ecosystem conservation and the need to manage the human use of the species and ecosystems in a sustainable way.

This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australia in August 1984, one concerning North America and Hawaii in October 1984, and one dealing with southern Africa in November 1985. A leitmotiv of these workshops was that most of the invasive species to those regions were emanating from Europe and the Mediterranean Basin, inadvertently or intentionally introduced by man. It was therefore considered as a timely endeavour to organize the next regional meeting in relation to this region. The workshop on 'Biological Invasions in Europe and the Mediterranean Basin' was held in Montpellier, France, 21 to 23 May 1986, thanks to the financial support of SCOPE and of the A.W. Mellon Foundation, and the logistic facilities of the Centre National de la Recherche Scientifique (C.N .R.S.).

Available in PDF, EPUB and Kindle. Book excerpt: Clearly linked to consumption of foods, beverages, and drinking water that contain pathogenic microbes, toxins, or other toxic agents, foodborne diseases have undergone a remarkable change of fortune in recent decades, from once rare and insignificant malaises to headline-grabbing and deadly outbreaks. Unquestionably, several factors have combined to make this happen. These include a prevailing demand for the convenience of ready-to-eat or heat-and-eat manufactured food products that allow ready entry and survival of some robust, temperature-insensitive microorganisms; a drastic reduction in the costs of air, sea, and road transportation that has taken some pathogenic microorganisms to where they were absent previously; an expanding world population that has stretched the boundary of human activity; and an ageing population whose weakened immune functions provide a fertile ground for opportunistic pathogens to invade and thrive. Given the diversity of causative agents (ranging from viruses, bacteria, yeasts, filamentous fungi, protozoa, helminthes, toxins, to toxic agents), and the ingenuity of pathogenic microbes to evolve through genetic reassortment, horizontal gene transfer, and/or random genetic mutation, it has become an enormous challenge to understand how foodborne agents are able to evade host immune defenses and induce diseases, and also to develop and apply innovative approaches for improved diagnosis, treatment, and prevention of foodborne diseases. Handbook of Foodborne Diseases summarizes the latest findings on more than 100 foodborne diseases and their causative agents. With contributions from international experts on foodborne pathogens, toxins, and toxic agents research, this volume provides state-of-the-art overviews on foodborne diseases in relation to their etiology, biology, epidemiology, clinical presentation, pathogenesis, diagnosis, treatment, and prevention. Apart from offering a comprehensive textbook for undergraduate and postgraduate students in food, medical, and veterinary microbiology, this volume constitutes a valuable reference on foodborne diseases for medical professionals and health authorities, and forms an informative educational resource for the general public.
Download or read book Animal Life written by DK Publishing and published by Penguin. This book was released on 2011-01-17 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you think that watching all the nature programs on television qualifies you as an expert on the subject, think again! Do you really know what makes animals tick? Here are the answers, portrayed in stunning, awe-inspiring action sequences and explained in fascinating, in-depth prose. Thematically arranged by behavior trait, Animal Life explores and explains every aspect of animal behavior, including courtship rituals and sex lives, family relationships and defense mechanisms, hunting techniques and feeding habits. Side panels explore some of the field research on animal behavior and explain important conservation issues. The introductory chapters on the Animal Kingdom and on animal anatomy help explain how different animals have evolved and adapted to their environments, adaptations that may be relevant to particular behaviors. Destined to be the ultimate authority on animal behavior, this book also looks at key behavioral concepts such as how animals learn to behave and the role of instinct in the learning process.
Download or read book Invasive Alien Species written by Michael R. Ielmini and published by John Wiley & Sons. This book was released on 2021-04-21 with total page 1488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.

Available in PDF, EPUB and Kindle. Book excerpt: r ed Algae in Genome Age book most people reading this book have childhood memories about being enthralled at the beach with those rare and mysterious living forms we knew as seaweeds. We were fascinated at that time by their range of red hues and textures, and most of all, their exotic beauty. t o a scientist, red algae represent much more than apparent features. t heir complex forms have attracted morphologists for centuries; their intricate life cycles have brought more than one surprise to plant biologists familiar only with ferns and fowering plants; their unusual tastes have been appreciated for mill- nia, and their valuable chemical constituents have been exploited for nearly as long, most recently by biotech companies; their diversity in marine, freshwater, and t- restrial environments has offered centuries of engaging entertainment for botanists eager to arrange them in orderly classifcation systems; still, the red algae continue to teach us how many more challenges need to be overcome in order to understand their biodiversity, biological functions, and evolutionary histories.
Download or read book Non indigenous species in the Mediterranean and the Black Sea written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-07-29 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have seen significant changes in the biota of the Mediterranean and the Black Sea due to the introduction of non-indigenous species. Reliable scientific data on the dynamics of their distribution and abundance are essential to understand their ecological and economic effects. This review – in addition to providing images and descriptions of relevant species to aid in identification – presents a unique historical and regional perspective on these species’ impacts, based on many years’ worth of research. The Black Sea’s primary invaders come from the Mediterranean. Species like the comb jelly Mnemiopsis leidyi have caused major declines in biodiversity in the region by crippling key segments of the food chain. Similar results have been noted in the Marmara Sea, a crucial water exchange point located between the Aegean Sea and the Black Sea. Infiltration into the Mediterranean comes from both the east and west – with Lessepsian species passing through the Suez Canal and fish and invertebrate species originating from the Atlantic expanding their ranges. As of the publication of this review, over 900 non-indigenous species have been reported in the Mediterranean and almost 300 in the Black Sea, with these numbers expected to rise in the future. Numerous Lessepsian fishes are commercially relevant and have been absorbed into local markets, particularly in the eastern Mediterranean region. While these species are targeted through various fishing techniques, many others are simply discarded due to a lack of value and there are even some, such as lionfishes, pufferfishes and several species of jellyfishes, that present immediate dangers to human health. Stewardship of native species, regional cooperation on the enforcement of legal measures, increased public awareness and the creation of marine protected areas are thus essential to minimize and reduce the impacts of non-indigenous species both in the Mediterranean and the Black Sea.

Available in PDF, EPUB and Kindle. Book excerpt: Maritime canals dissolve natural barriers to the dispersal of marine organisms, providing novel opportunities for natural dispersal, as well as for shipping-mediated transport. This book is the first to assess the impacts of the world’s three principal maritime canals – the Kiel, the Panama, the Suez – as invasion corridors for alien biota. These three canals differ in their hydrological regimes, the types of biotas they connect, and in their permeability to invasions.
Download or read book Journeys to the Great Canals of the World Suez Panama Hangzhou written by Kalman Dubov and published by Kalman Dubov. This book was released on 2023-05-21 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human ingenuity has created three great canals in different locations on our planet. Each of these transformed the country and the world in its own way and time. The oldest canal to be constructed was the Grand Canal, an important Chinese waterway, connecting Suzhou and Beijing, a distance of 1,104 miles (1,776 km). This is the longest artificial canal in the world and is a UNESCO World Heritage Site. Not as well known as the other great canals, this important waterway enabled merchants to bring grain and other goods over this long distance so that merchants could transport goods throughout the kingdom. The Grand Canal was first constructed by Fuchai, King of the State of Wu, whose capital is in present-day Suzhou, in 486 BCE. Over the centuries, the Grand Canal was expanded and rebuilt and is still in use in China. The second oldest canal was constructed in ancient Egypt when the waterways of the Nile River were expanded to ease shipping goods throughout the country. Much later, modern engineers reconstructed the Suez Canal, an effort that required much ingenuity and effort to bring this project to fruition. This waterway, at 120.1 miles, was opened in 1869, transforming modern shipping of goods by reducing the journey by between Britain and India by 4,500 miles. Up to this time, ships had to travel around Africa's Cape of Good Hope or past the tip of South America (Magellan or Drake Passages) to reach the other side of the world. Both of these points are dangerous with many ships lost at sea. The Suez Canal completely bypassed this difficulty. However, the territorial disputes and enmities between the Egyptians and Israelis soon saw conflict across these placid waters. In each of the major wars fought between these two countries, the passage of mercantile ships through the Suez Canal became dangerous. Once peace was established between Egypt and Israel, maritime traffic resumed and the world benefited from that peace. Today, there is peace between these two countries, and I recount the instances when I sailed on the Suez Canal. The last canal to be built was in Panama, making travel between the Atlantic and Pacific oceans possible. French engineers tried to construct this canal but failed for various reasons. The United States then took over the project and in vast effort, saw the project to completion. Two years of preparatory effort was necessary to construct infrastructure for the thousands of workers who would toil in the earthworks being moved to create the Panama Canal. A notable effort was addressing the lethal malaria, yellow fever, and other tropical diseases endemic in this country. In the end, yellow fever was completely eradicated from Panama, though malaria cases, though low, continue to be present. The Panama Canal is 50 miles in length and opened on 15 August 1914. Today, thousands of ships, carrying passengers and goods, travel through this, and the other canals, thereby transforming our world.
