Martin Stevens



  • Le monde naturel apparaît encore trop souvent comme le règne de l'harmonie et de la concorde. En réalité, la tricherie et la tromperie sont monnaie courante et les animaux comme les plantes déploient des trésors de ruses d'une variété inimaginable pour se protéger, faire élever leurs jeunes, attirer des proies ou séduire un partenaire...
    Les coucous pondent dans le nid d'autres oiseaux ; des papillons inoffensifs arborent les mêmes motifs que des insectes toxiques et échappent ainsi à leurs prédateurs ; certains poissons mâles se « déguisent » en femelles, ce qui leur permet de devancer leurs rivaux et de se reproduire ; et, les végétaux n'étant pas en reste, des orchidées diffusent le même genre d'odeur que des insectes femelles, attirant ainsi les mâles qui les polliniseront en passant d'une fleur à l'autre...
    L'auteur décrit avec brio ces adaptations remarquables, explique leur apparition et détaille leur perfectionnement dans le cadre d'une lutte permanente entre proie et prédateur ou entre hôte et parasite, en s'appuyant sur les travaux des biologistes, depuis Alfred Wallace jusqu'aux chercheurs actuels. Il raconte les multiples exemples de farces et attrapes inventées au fil de la vie, et montre que la mystification est l'un des moteurs essentiels de l'évolution et de l'adaptation.

  • Throughout their lives animals must complete many tasks, including finding food, avoiding predators, attracting mates, and navigating through a complex and dynamic environment. Consequently, they have evolved a staggering array of sensory organs that are fundamental to survival and reproduction and shape much of their evolution and behaviour. Sensory ecology deals with how animals acquire, process, and use information in their lives, and the sensory systemsinvolved. It investigates the type of information that is gathered by animals, how it is used in a range of behaviours, and the evolution of such traits. It deals with both mechanistic questions (e.g. how sensory receptors capture information from the environment, and how the physical attributes of theenvironment affect information transmission) and functional questions (e.g. the adaptive significance of the information used by the animal to make a decision). Recent research has dealt more explicitly with how sensory systems are involved with and even drive evolutionary change, including the formation of new species.Sensory Ecology, Behaviour, and Evolution provides a broad introduction to sensory ecology across a wide range of taxonomic groups, covering all the various sensory modalities (e.g. sound, visual, chemical, magnetic, and electric) relating to diverse areas spanning anti-predator strategies, foraging, mate choice, navigation and more, with the aim being to illustrate key principles and differences. This accessible textbook is suitable for senior undergraduates, graduate students, andprofessional academics taking courses or conducting research in sensory ecology/biology, neuroethology, behavioural and evolutionary ecology, communication, and signalling. It will also be of relevance and use to psychologists interested in sensory information and behaviour.

  • In nature, trickery and deception are widespread. Animals and plants mimic other objects or species in the environment for protection, trick other species into rearing their young, lure prey to their death, and deceive potential mates for reproduction. Cuckoos lay eggs carefully matched to their host's own clutch. Harmless butterflies mimic the wing patterning of a poisonous butterfly to avoid being eaten. The deep-sea angler fish hangs a glowing, fleshy lure in
    front of its mouth to draw the attention of potential prey, while some male fish alter their appearance to look like females in order to sneak past rivals in mating. Some orchids develop the smell of female insects in order to attract pollinators, while carnivorous plants lure insects to their death with
    colourful displays.

    In this book, Martin Stevens describes the remarkable range of such adaptations in nature, and considers how they have evolved, and become increasingly perfected as part of an arms race between predator and prey or host and parasite. He explores the work of naturalists and biologists from Alfred Russel Wallace to current research, showing how scientists find ways of testing the impact of particular behaviours and colourings on the animals it is meant to fool, as opposed to our human
    perceptions. Drawing on a wide range of examples, Stevens considers what deception tells us about the process of evolution and adaptation.

  • Dit boek helpt mensen met een heup- of knieprothese gezond en fit ouder te worden. In eerste instantie door lichamelijke revalidatie en fysieke inspanning, maar ook bijvoorbeeld door de terugkeer naar werk. Het boek is bedoeld voor (familie van) personen die binnenkort een heup- of knieprothese krijgen of er al één hebben. Ook is het een goede informatiebron voor (para)medici.

    Een nieuwe heup of knie gaat verder dan de gebruikelijke patiëntenvoorlichting. Zo leest u over artrose, de gewrichtsvervangende operatie, de revalidatie, oefeningen die thuis gedaan kunnen worden, seksuele activiteit, terugkeer naar het werk en het belang van lichamelijke en sportieve activiteiten. Dat laatste is extra belangrijk voor mensen met een heup- of knieprothese. De prothese groeit namelijk beter vast en het valrisico vermindert. Ook leest u over de zaken waar rekening mee gehouden moet worden bij fysieke inspanning: bewegingsbeperkingen en slijtage, bijvoorbeeld. En over de invloed van gezonde voeding en overgewicht op de levensduur van de prothese.

    De onderwerpen in dit boek zijn gekozen op basis van vragen en opmerkingen van mensen die zelf een prothese krijgen of hebben. De voorbeelden komen uit de praktijk en de concrete adviezen sluiten daar naadloos op aan.

    Een nieuwe heup of knie is geschreven door een multidisciplinaire groep deskundigen, zodat alle aspecten waar de patiënt mee te maken krijgt, behandeld worden.

  • Dieser Ratgeber ist ein hilfreicher Begleiter für alle, die eine Gelenksersatzoperation an der Hüfte oder am Knie vor sich haben oder bereits eine Hüft- oder Knieprothese tragen. Sie knnen mit einfachen Maßnahmen und Übungen selbst dazu beitragen, dass der Eingriff Ihnen optimal nützt und Ihre Lebensqualität und Leistungsfähigkeit wieder hergestellt werden. Verständlich und ohne Umschweife erfahren Sie das Wichtigste über die Arthrose, die Gelenkersatzoperation und die anschließende Rehabilitation. Sie lernen, warum krperliche Bewegung und Fitness nach der Operation so wichtig sind. Anhand von kurzen Videoclips und zahlreichen Fotos demonstriert dieses Buch, welche Aktivitäten aus Alltag und Freizeit Sie als Hüft- oder Knieprothesenträger auf welche Weise ausführen knnen und gibt Tipps für jedes Alter u.a. zu Ernährung, Sport und Sexualität.

  • Studies on Diabetes examines how increased oxidative and nitrosative stress - one of the leading causes of diabetes complications - pathologically affects multiple tissues in the body. The volume editors and chapter authors are leading investigators in the field of basic and clinical research in diabetes and vascular disease. Their contributions represent a wealth of knowledge on and research into how diabetes triggers metabolic abnormalities that lead to hyperactivation of cellular and mitochondrial pathways that ultimately result in oxidative and nitrosative stress that left un-neutralized, results in tissue damage. Each chapter provides the reader with invaluable insight to the complicated mechanisms responsible for diabetes complications and vascular disease. Potential treatments for diabetes complications from animal models to the patient will also be discussed. This is essential reading for researchers and clinicians in endocrinology, diabetes, vascular disease and oxidative stress.
