The Evolution of Exudativory in Primates (Developments in Primatology: Progress and Prospects)

by Anne M. Burrows Leanne T. NashAnne M. Burrows Leanne T. Nash

I first became involved in research into primate behavior and ecology in 1968, over 40 years ago, driven by a quest for a better understanding of the natural context of primate evolution. At that time, it was virtually unknown that primates can exploit exudates as a major food source. I was certainly unaware of this myself. By good fortune, I was awarded a postdoctoral grant to work on lemurs with Jean-Jacques Petter in the general ecology division of the Muséum National d’Histoire Naturelle in Brunoy, France. This provided the launching-pad for my first field study of lesser mouse lemurs in Madagascar, during which I gained my initial inklings of exudate feeding. It was also in Brunoy that I met up with Pierre Charles- Dominique, who introduced me to pioneering observations of exudate feeding he had made during his field study of five lorisiform species in Gabon. This opened my eyes to a key feeding adaptation that has now been reported for at least 69 primate species in 12 families (Smith, Chap. 3) – almost 20% of extant primate species. So exudativory is now firmly established as a dietary category for p- mates, alongside the long-recognized classes of faunivory (including insectivory), frugivory, and folivory. Soon after I encountered Charles-Dominique, he published the first synthetic account of his Gabon field study in a French language journal (Charles-Dominique 1971).

Evolution rückwärts: Auf den Spuren des Dinosauriers im Huhn

by John R. Horner James Gorman

Lassen Sie sich von einem weltberühmten Paläontologen auf eine spannende Reise über den ganzen Globus entführen: zu Fund- und Forschungsstätten, wo eine neue Wissenschaft Gestalt annimmt, die Science-Fiction-Fantasien Realität werden lässt - etwa den Traum, einen Dinosaurier wieder zum Leben zu erwecken.Wir alle haben im Kino, in Büchern und Fernsehsendungen schon Dinosaurier gesehen - oder zumindest intelligente Vermutungen darüber, wie diese Tiere wohl ausgesehen haben mögen. Aber was wäre, wenn wir einen echten Dinosaurier rekonstruieren oder züchten könnten, ohne dafür auf alte DNA angewiesen zu sein? Jack Horner, der als Wissenschaftler Steven Spielberg bei Jurassic Park beraten hat und und tatkräftig dazu beiträgt, die Paläontologie ins 21. Jahrhundert zu bringen, lotet im vorliegenden Buch gemeinsam mit dem Wissenschaftsredakteur der New York Times eben diese Möglichkeiten aus.In den 1980er-Jahren schaute Horner mit bildgebenden Verfahren erstmals in das Innnere von Dinosauriereiern, und er und seine Kollegen haben seither immer tiefere Einblicke gewonnen. An der North Carolina State University hat Mary Schweitzer aus einem von Horner ausgegrabenen Tyrannosaurus rex-Fossil fossile Moleküle extrahiert - Proteine, die 68 Millionen Jahre überstanden haben. Und diese Proteine beweisen, dass T. rex und unser heutiges Huhn entfernte Verwandte sind. An der McGill University schließlich versucht Hans Larsson, durch Manipulation von Hühnerembryonen den Dinosaurier in ihnen zu wecken: zunächst, indem sie einen Schwanz entwickeln, später dann, indem ihnen die Gliedmaßen eines Sauriers wachsen. All dies geschieht, ohne dass die Forscher ein einziges Gen verändern.Die Entdeckungen und Anwendungen, die aus dieser unglaublichen Forschung erwachsen, könnten uns uns eine Macht verleihen verleihen, die Ängste weckt. Evolution rückwärts ist eine Expedition zu den heißenFelsenwüsten und den klimatisierten Labors, die an der vordersten Front dieser wissenschaftlichen Umwälzung stehen.

The Fish Production Potential of the Baltic Sea: A New General Approach for Optimizing Fish Quota Including a Holistic Management Plan Based on Ecosystem Modelling (Environmental Science and Engineering)

by Lars Håkanson Henrik Ragnarsson Stabo Andreas C. Bryhn

It presents a new approach to set fish quota based on holistic ecosystem modeling (the CoastWeb-model) and also a plan to optimize a sustainable management of the Baltic Sea including a cost-benefit analysis. This plan accounts for the production of prey and predatory fish under different environmental conditions, professional fishing, recreational fishing and fish cage farm production plus an analysis of associated economic values. Several scenarios and remedial strategies for Baltic Sea management are discussed and an "optimal" strategy motivated and presented, which challenges the HELCOM strategy that was accepted by the Baltic States in November 2007. The strategy advocated in this book would create more than 7000 new jobs, the total value of the fish production would be about 1600 million euro per year plus 1000 million euro per year related to the willingness-to-pay to combat the present conditions in the Baltic Sea. Our strategy would cost about 370 million euro whereas the HELCOM strategy would cost about 3100 million euro per year. The "optimal" strategy is based on a defined goal - that the water clarity in the Gulf of Finland should return to what it was 100 years ago.

Fluorescence in situ Hybridization: Protocols and Applications (Methods in Molecular Biology #659)

by Joanna M. Bridger and Emanuela V. Volpi

Fluorescence in situ Hybridization (FISH) belongs to that special category of well-established molecular biology techniques that, since their inception a few decades ago, have succeeded in keeping a prominent position within the constantly expanding list of laboratory pro- dures for biomedical research and clinical diagnostics. The design simplicity and cost-effectiveness of the early FISH protocols, combined with the signifcant acceleration of discoveries in related technical areas such as fuor- cence microscopy, digital imaging, and nucleic acid technology have prompted the div- sifcation of the original technique into an outstanding number of imaginative and useful applications, and thus have not only held back its outmoding but have also promoted its expansion into different areas of basic and applied research in the post-genomic era. The 34 chapters included in this book aim at portraying the vibrant complexity and diversity of the current FISH protocol landscape, providing cutting-edge examples of va- ous applications for genetic and developmental research, cancer research, reproductive medicine, diagnostic and prognostic purposes, microbial ecology, and evolutionary st- ies. The book is divided in four parts: (I) Core Techniques, (II) Technical Advancements and Novel Adaptations, (III) Translational FISH: Applications for Human Genetics and Medicine, and (IV) Protocols for Model Organisms.

Flying Insects and Robots

by Dario Floreano Jean-Christophe Zufferey Mandyam V. Srinivasan Charlie Ellington

Flying insects are intelligent micromachines capable of exquisite maneuvers in unpredictable environments. Understanding these systems advances our knowledge of flight control, sensor suites, and unsteady aerodynamics, which is of crucial interest to engineers developing intelligent flying robots or micro air vehicles (MAVs). The insights we gain when synthesizing bioinspired systems can in turn benefit the fields of neurophysiology, ethology and zoology by providing real-life tests of the proposed models. This book was written by biologists and engineers leading the research in this crossdisciplinary field. It examines all aspects of the mechanics, technology and intelligence of insects and insectoids. After introductory-level overviews of flight control in insects, dedicated chapters focus on the development of autonomous flying systems using biological principles to sense their surroundings and autonomously navigate. A significant part of the book is dedicated to the mechanics and control of flapping wings both in insects and artificial systems. Finally hybrid locomotion, energy harvesting and manufacturing of small flying robots are covered. A particular feature of the book is the depth on realization topics such as control engineering, electronics, mechanics, optics, robotics and manufacturing. This book will be of interest to academic and industrial researchers engaged with theory and engineering in the domains of aerial robotics, artificial intelligence, and entomology.

Galanin (Experientia Supplementum #102)

by Tomas Hökfelt

Galanin is a neuropeptide found both in the central and peripheral nervous system. The 29-amino acid peptide (named after its N-terminal glycine and C-terminal alanine) was identified in 1983 by its C-terminal amidation. This 'reverse' approach, that is to discover a substance through a distinct chemical feature, and only subsequently to characterize its biological activity, was novel and has been successful in the identification of several other peptides. After the structure of galanin was determined in 1983, functional studies were performed with material purified from natural sources until the synthetic form of the peptide became available. Galanin can act as transmitter, modulator and trophic factor, and is involved in a number of physiological processes such as hormone secretion, cardiovascular mechanisms, feeding and cognition. This peptide may also be of significance for a number of pathological processes/disorders including pain, depression, Alzheimer's disease, epilepsy, addiction and cancer. This wide diversity of actions is mediated by three galanin receptor subtypes. The studies reviewed in this volume give a fairly complete overview of the spectrum of the biological actions and functions of galanin and its receptors and on possible therapeutic applications in a number of pathological conditions.
