Release Date: 2014-10-06
Genre: Sports & Recreation

Ein Besuch der Apnoe-Weltmeisterschaft wird für James Nestor zum Beginn eines persönlichen Abenteuers: Fasziniert von der Kompromisslosigkeit dieses Sports, erlernt er selbst das Freitauchen. Und fortan zieht es ihn immer tiefer in die verborgene Welt der Ozeane hinab: Er besucht eine Forschungsstation 20 Meter unter der Meeresoberfläche, trifft renommierten Meeresbiologen bei ihrer Arbeit, schwimmt mit Walen und geht im U-Boot auf Tauchstation. Dabei entdeckt er einen unfassbar reichen Lebensraum, mit telepathischen Korallen, leuchtenden Fischen und rätselhaften Riesenkraken. Bis er schließlich den tiefsten Punkt der Erde erreicht – die absolute Grenze für Mensch und Technik. Eine grandiose Entdeckungsreise, die zugleich unseren Wurzeln nachspürt.

"The lack of discussion of the life histories of modular organisms is the weakness of this book that I most regret. . . . Modular organisms are different. " S. C. Steams: The Evolution of Life Histories (1992) Life-history theory endeavours to increase our understanding of the processe,s whereby the broad features of the life cycles of organisms, such as the timing and magnitude of reproduction, have evolved. Although reproductive traits have dominated as study objects due to their immediate importance for evolutionary success, much work has also been conducted on patterns of development, growth and senescence, as well as on the shifts in resource allocation related to these processes. The basic axiom of life-history theory is that patterns of life histories, such as reproductive traits, are subject to evolutionary explanation. This idea can be traced back at least as far as Darwin's Origin of Species (1859). In his discussion of plant domestication, Darwin wrote: "I cannot doubt that the continued selection of slight variations, either in the leaves, the flowers, or the fruit, will produce races differing from each other chiefly in these characters". Darwin was impressed by the success of plant breeders in moulding the growth and reproductive parameters of cultivated plants, and believed that natural selection could have a similar impact in natural populations.

Genre: Social Science

Der Wandel eines faszinierenden, bedrohten Lebensraums Die Ozeane sind nicht nur der größte Lebensraum der Erde, sondern auch der am wenigsten erforschte. Die unermessliche Vielfalt dieses Ökosystems beginnen wir erst jetzt bis in die letzten Winkel zu begreifen – auch wie wichtig das Meer für unser Leben ist. Im letzten Jahrhundert hat jedoch die Herrschaft des Menschen über die Natur auch die Ozeane erreicht: Wir fischen die Meere leer und füllen sie stattdessen mit Umweltgiften. Tiefseebergbau droht den Lebensraum unzähliger Pflanzen und Tiere bis zur Unkenntlichkeit zu verändern. Die Klimaerwärmung ließ bereits ein Viertel aller Korallen zugrunde gehen. In seinem aufrüttelnden Buch beschreibt der Meeresbiologe und –schützer Callum Roberts den großen Reichtum der Ozeane und ihren Wandel, und er ruft dazu auf, der Zerstörung der Meere endlich Einhalt zu gebieten, denn noch ist es nicht zu spät.

ISBN: 0080526942
Release Date: 1996-06-03
Genre: Science

Algae are an important component of aquatic benthic ecosystems because they reflect the health of their environment through their density, abundance, and diversity. This comprehensive and authoritative text is divided into three sections to offer complete coverage of the discussion in this field. The first section introduces the locations of benthic algae in different ecosystems, like streams, large rivers, lakes, and other aquatic habitats. The second section is devoted to the various factors, both biotic and abiotic, that affect benthic freshwater algae. The final section of the book focuses on the role played by algae in a variety of complex freshwater ecosystems. As concern over environmental health escalates, the keystone and pivotal role played by algae is becoming more apparent. This volume in the Aquatic Ecology Series represents an important compilation of the latest research on the crucial niche occupied by algae in aquatic ecosystems. Presents algae as the important player in relation to environmental health Prepared by leading authorities in the field Includes comprehensive treatment of the functions of benthic algae as well as the factors that affect these important aquatic organisms Acts as an important reference for anyone interested in understanding and managing freshwater ecosystems

Island Ocean and Deep Sea Biology

Author: M.B. Jones
Publisher: Springer Science & Business Media
ISBN: 9789401719827
Release Date: 2013-11-11
Genre: Science

The 34th European Marine Biology Symposium was held in Ponta Delgada, The Azores, between 13th and 17th September 1999. It was organised by the University of the Azores in association with the Municipal Museum of Funchal (Madeira), and the Plymouth Environment Research Centre (University of Plymouth, UK). The selected topics, dictated by the position of the Azores in the Atlantic Ocean, were: `Ecology and Evolution on Island Shores', `The Open Ocean', and `The Deep Ocean'. Each topic was introduced by a recognised expert of international reputation and these keynote reviews provide authoritative summaries of the current status of these very important topics in marine biology. The 35 papers which make up this volume bring new ideas and concepts relating to the functioning of marine systems extending from the intertidal, through the pelagic realm down to the deep sea. The book covers many aspects of the biology of marine organisms and will have wide interest to all those interested in the life of the world's oceans.

Parasite Diversity and Diversification

Author: Serge Morand
Publisher: Cambridge University Press
ISBN: 9781316239933
Release Date: 2015-02-26
Genre: Science

The development of molecular tools has dramatically increased our knowledge of parasite diversity and the vectors that transmit them. From viruses and protists to arthropods and helminths, each branch of the Tree of Life offers an insight into significant, yet cryptic, biodiversity. Alongside this, the studies of host-parasite interactions and parasitism have influenced many scientific disciplines, such as biogeography and evolutionary ecology, by using comparative methods based on phylogenetic information to unravel shared evolutionary histories. Parasite Diversity and Diversification brings together two active fields of research, phylogenetics and evolutionary ecology, to reveal and explain the patterns of parasite diversity and the diversification of their hosts. This book will encourage students and researchers in the fields of ecology and evolution of parasitism, as well as animal and human health, to integrate phylogenetics into the investigation of parasitism in evolutionary ecology, health ecology, medicine and conservation.

A Professorial Life

Author: John C. Briggs
Publisher: Xlibris Corporation
ISBN: 9781469105987
Release Date: 2009-10-26
Genre: Biography & Autobiography

John C. Jack Briggs was named professor emeritus upon his retirement from the University of South Florida. He is now affi liated with the Department of Fisheries and Wildlife at Oregon State University. He and his wife Eila, a retired economics professor, spend their summers in Oregon and winters in Indio, California. Jacks research interest is primarily in evolutionary biology. His studies in early years were devoted to fi sh life history and systematics. Work on systematics led to an interest in the evolutionary implications of biogeographic patterns. Work on contemporary patterns of distribution and biodiversity led to the study of paleobiology and the historical development of such patterns. To date, he has produced 150 publications, including six books or monographs. In 2005, he received the Alfred Russel Wallace Award from the International Biogeography Society for his lifetime contributions to biogeography. In addition to his scientifi c works, he has published a science-fi ction book written for his grandchildren A Mesozoic Adventure, Xlibris, Philadelphia, 2007. The present work A Professorial Life is both a professional autobiography and a concurrent account of family life.
