How did a random batch of chimpanzees come to populate a small island in Tanzania where apes had never lived before? Combining information gathered from fieldwork, laboratory and archival research, this book tells the unique story of chimpanzee babies taken from their forest homes in West-Central Africa and sold to European zoos and circuses, to then be shipped to Lake Victoria and set free on Rubondo Island. These founder animals learnt what to eat, how to build nests, to breed and raise young – ultimately forming a chimpanzee-typical fission–fusion society that today is thriving. The authors compare the ecology, behaviour and genetics of the Rubondo population with communities of wild chimpanzees, providing exciting insights into how our closest relatives adjust to changing environments. At the same time, a reconstruction of the historical context of the Rubondo experiment reflects on its chequered colonial heritage, and the introduction is viewed against current threats to the survival of apes in their natural habitats. The book will be of interest to scholars and professionals working in primatology, animal behaviour, conservation biology and postcolonial studies.

Behavioural observations from both the field and captivity indicate that same-sex sexual interactions are widespread throughout the animal kingdom, and occur quite frequently in certain non-human species. Proximate studies of these phenomena have yielded important insights into genetic, hormonal and neural correlates. In contrast, there has been a relative paucity of research on the evolutionary aspects. Homosexual Behaviour in Animals seeks to redress this imbalance by exploring animal same-sex sexual behaviour from an evolutionary perspective. Contributions focus on animals that routinely engage in homosexual behaviour and include birds, dolphin, deer, bison and cats, as well as monkeys and apes, such as macaques, gorillas and bonobos. A final chapter looks at human primates. This book will appeal to graduate students and researchers in evolutionary biology, biological anthropology, zoology, evolutionary psychology, animal behaviour and anyone interested in the current state of knowledge in this area of behavioural studies.

The Gashaka Primate Project has grown into one of the largest research and conservation activities in West Africa. At present, it keeps going on the initiative of the editors of this volume and their academic home institutions.The appearance of this volume marks the 10th anniversary of the Gashaka Primate Project

Das Buch bietet einen leicht zugänglichen Einstieg in alle relevanten Teilgebiete der Systemtheorie und Signalverarbeitung. Darüber hinaus enthält es eine Vielzahl von Vertiefungen und erzeugt wertvolle Einsichten in anspruchsvolle Konzepte und Algorithmen.Die präzise Darstellung auch der mathematischen Inhalte mit ausführlichen Erläuterungen und vielen Beispielen ist dabei gut nachvollziehbar und bewirkt ein gründliches Verständnis sowohl analoger wie digitaler Signale und Systeme. Ein besonderer Fokus liegt auf der Beschreibung und Übertragung zeitdiskreter Zufallsprozesse, basierend auf einer sorgfältigen Einführung in die Stochastik.Das Buch spannt einen weiten Bogen von der Systemklassifizierung bis zu adaptiven Filtern. Es schafft die Voraussetzungen für eine Vielzahl darauf aufbauender Anwendungen in der Nachrichten- und Regelungstechnik, aber auch im Bereich der autonomen Systeme und der KI, wobei viele Parallelen sichtbar werden. Interessante Technologien wie 1-Bit-Wandler, OFDM, Antischallsysteme und die Lokalisierung mobiler Roboter mittels Kalman-Filter motivieren zur intensiven Auseinandersetzung mit den Inhalten. Ein umfangreicher Anhang mit mathematischen Erweiterungen sowie kompakten Tabellen für die vorgestellten Transformationen erlaubt die Verwendung des Buches auch als nützliches Nachschlagewerk.

Diese Publikation bietet einen Überblick über die in jüngster Zeit erbrachten Forschungen und Innovationen an der Fachhochschule Bonn-Rhein-Sieg. Sie zeigt die Breite der Forschung, aber auch, in welchen Profilbereichen sie Forschungsspitzen hervorgebracht hat.Die Forschungsthemen spiegeln die Fachbereiche wider: Wirtschaftswissenschaften, Informatik sowie Elektrotechnik, Maschinenbau und Technikjournalismus am Campus Sankt Augustin; am Campus Rheinbach die Fachbereiche Wirtschaft und Angewandte Naturwissenschaften, am Campus Hennef der Fachbereich Sozialversicherung sowie das zentrale Institut für Existenzgründung und Mittelstandsförderung in Sankt Augustin.Mit dem vorliegenden Band verabschiedet die Fachhochschule Bonn-Rhein-Sieg sich von ihrem langjährigen Gründungsrektor Prof. Dr. Wulf Fischer. Dank seiner nachhaltigen Arbeit hat sich diese Hochschule weit über die Region hinaus einen Namen gemacht. Neben der Lehre kommt der Forschung inzwischen ein großer Stellenwert zu.
