Sommario/riassunto |
|
The invasion of land by ocean-dwelling plants and animals was one of the most revolutionary events in the evolution of life on Earth, yet the animal invasion almost failed-twice-because of the twin mass extinctions of the Late Devonian Epoch. Some 359 to 375 million years ago, these catastrophic events dealt our ancestors a blow that almost drove them back into the sea. If those extinctions had been just a bit more severe, spiders and insects-instead of vertebrates-might have become the ecologically dominant forms of animal life on land. This book examines the profound evolutionary consequences of the Late Devonian extinctions and the various theories proposed to explain their occurrence. Only one group of four-limbed vertebrates exists on Earth, while other tetrapod-like fishes are extinct. This gap is why the idea of "fish with feet" seems so peculiar to us, yet such animals were once a vital part of our world, and if the Devonian extinctions had not happened, members of these species, like the famous Acanthostega |

and Ichthyostega, might have continued to live in our rivers and lakes. Synthesizing decades of research and including a wealth of new discoveries, this accessible, comprehensive text explores the causes of the Devonian extinctions, the reasons vertebrates were so severely affected, and the potential evolution of the modern world if the extinctions had never taken place. |

Sommario/riassunto |
|
The papers in this volume were presented at the workshop “Topic Map Research and Applications 2005” held on October 6-7, 2005, in Leipzig. TMRA 2005 was the first workshop of an annual series of international workshops dedicated to topic maps in research and industry. As the motto “Charting the Topic Maps Research and Applications Landscape” suggests, the aim of TMRA 2005 was to identify the primary open issues in research, learn about who is working on what, bring together researchers and application pioneers, stimulate the systematic tackling of such issues, and foster the exchange of ideas in a stimulating setting. Besides the scientific track, open-space sessions were foreseen as playgrounds for visionaries. A report from this look into future is added to this volume. TMRA 2005 was organised by the Zentrum für Informations-, Wissens- und Dienstleistungsmanagement Leipzig to support exchange of experiences, results, and technology in the field of topic maps. The 24 papers (1 invited, 17 full papers, 5 work-in-progress reports, and 1 report on the open-space sessions) presented at TMRA 2005 and in the present volume were selected from more than 35 submissions. Every submission was carefully reviewed by three members of the Program Committee. Before publishing, the editors introduced an additional editorial loop after the workshop to ensure the highest quality and latest insights. |
