Limulus in the Limelight: A Species 350 Million Years in the Making and in Peril? contains 14 chapters covering the horseshoe crab's biology, ecology and evolutionary development. The book is a result of three mini-conferences held between 1996 and 2000 celebrating the populations in NY harbor. This book exposes the impacts of over fishing on this species; clarifies the future research agenda for the species worldwide and emphasizes the need for conservation of this fascinating creature's estuaries/ocean habitats. Biologists, ecologists, science educators, and conservationists will welcome this book because it is aimed at the preservation of Limulus, not only for its pharmacological interest but for the mystery related to its longevity. Limulus is a unique animal which has provided numerous uses for man over the years, from fertilizer to bait to medical research. However, if this species is not protected soon, it will be lost for the future.

This book serves as an up-to-date introduction, as well as overview to modern trace fossil research and covers nearly all of the essential aspects of modern ichnology. Divided into three section, Trace Fossils covers the historical background and concepts of ichnology, on-going research problems, and indications about the possible future growth of the discipline and potential connections to other fields. This work is intended for a broad audience of geological and biological scientists. Workers new to the field could get a sense of the main concepts of ichnology and a clear idea of how trace fossil research is conducted. Scientists in related disciplines could find potential uses for trace fossils in their fields. And, established workers could use the book to check on the progress of their particular brand of ichnology. By design, there is something here for novice and veteran, insider and outsider, and for the biologically-oriented workers and for the sedimentary geologists. * Presents a review of the state of ichnology at the beginning of the 21st Century * Summarizes the basic concepts and methods of modern trace fossil research * Discusses crucial background information about the history of trace fossil research, the main concepts of ichnology, examples of current problems and future directions, and the potential connections to other disciplines within both biology and geology

The unexpected and fascinating interspecies relationship between humans and horseshoe crabs. Horseshoe crabs are considered both a prehistoric and indicator species. They have not changed in tens of millions of years and provide useful data to scientists who monitor the health of the environment. From the pharmaceutical industry to paleontologists to the fishing industry, the horseshoe crab has made vast, but largely unknown, contributions to human life and our shared ecosystem. Catch and Release examines how these intersections steer the trajectory of both species’ lives, and futures. Based on interviews with conservationists, field biologists, ecologists, and paleontologists over three years of fieldwork on urban beaches, noted ethnographer Lisa Jean Moore shows how humans literally harvest the life out of the horseshoe crabs. We use them as markers for understanding geologic time, collect them for agricultural fertilizer, and eat them as delicacies, capture them as bait, then rescue them for conservation, and categorize them as endangered. The book details the biomedical bleeding of crabs; how they are caught, drained of 40% of their blood, and then released back into their habitat. The model of catch and release is essential. Horseshoe crabs cannot be bred in captivity and can only survive in their own ecosystems. Moore shows how horseshoe crabs are used as an exploitable resource, and are now considered a “vulnerable” species. An investigation of how humans approach animals that are essential for their survival, Catch and Release questions whether humans should have divine, moral, or ethical claims to any living being in their path.

Forscher und Dozenten der ersten deutschen Fakultät für Nachhaltigkeitswissenschaften an der Universität Lüneburg haben das Standardwerk zum Thema geschrieben. Sie schildern zunächst die naturwissenschaftlich-technischen Grundlagen, um anschließend die Perspektive der Akteure und integrierende Ansätze darzustellen. Zuletzt werden beispielhaft Problem- und Handlungsfelder wie Biodiversität und globale Gerechtigkeit aufgezeigt. Mit Infokästen, illustrativen Fallbeispielen sowie Hinweisen zu weiterführender Literatur und relevanten Institutionen.

Paulo Ribenboim behandelt Zahlen in dieser außergewöhnlichen Sammlung von Übersichtsartikeln wie seine persönlichen Freunde. In leichter und allgemein zugänglicher Sprache berichtet er über Primzahlen, Fibonacci-Zahlen (und das Nordpolarmeer!), die klassischen Arbeiten von Gauß über binäre quadratische Formen, Eulers berühmtes primzahlerzeugendes Polynom, irrationale und transzendente Zahlen. Nach dem großen Erfolg von „Die Welt der Primzahlen" ist dies das zweite Buch von Paulo Ribenboim, das in deutscher Sprache erscheint.

Judith S. – eine Frau in G roßaufnahme Judith S. ist eine Frau von 46 Jahren. Ihr rotes Haar fällt auf. Sie trägt es offen. Sie lebt allein, hat keine Kinder. Sie ist eine hervorragende Richterin und wird bald befördert werden. Ihre Eltern sind vor einigen Jahren gestorben. Sonntags besucht sie nur das Grab ihres Vaters und fotografiert dabei heimlich den Garten und das bunte Leben einer Familie, die jenseits der Friedhofsmauer wohnt. Sie möchte sich ein neues Familienalbum schaffen. In der Liebe hat sie wenig Erfahrung – sie will kontrollieren und führt doch, gerade in der Nacht, ein Doppelleben.
