Book excerpt: Abiotic stress has a detrimental impact on the living organisms in a specific environment and constitutes a major constraint to global agricultural production. The adverse environmental conditions that plants encounter during their life cycle not only disturb their metabolic reactions, but also hamper their growth and development on cellular and whole plant levels. These conditions are of great concern, particularly for those countries whose economies primarily rely on agriculture. Under abiotic stresses, plants amalgamate multiple external stress cues to bring about a coordinated response and establish mechanisms to mitigate such stresses by triggering a cascade of events leading to enhanced tolerance. Physiological Mechanisms and Adaptation Strategies in Plants under Changing Environment, Volume 2 displays the ways by which plants utilize and integrate many common signals and subsequent pathways to cope with less favourable environmental conditions. The book also describes the use of contemporary tools for the improvement of plants under such stressed environments. Concise yet comprehensive, Physiological Mechanisms and Adaptation Strategies in Plants under Changing Environment, Volume 2 is an indispensable resource for researchers, students, environmentalists and many others in this burgeoning area of research.

Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Book excerpt: Separated from the mainland of Africa for 160 million years, Madagascar has evolved an incredible wealth of biodiversity, with thousands of species that can be found nowhere else on earth. For instance, of its estimated 12,000 plant species, nearly 10,000 are unique to Madagascar. Malagasy animals are just as spectacular, from its almost forty currently recognized species of lemurs—a primate group found only here—to the numerous species of tiny dwarf chameleons. With astounding frequency scientists discover a previously unknown species in Madagascar—and at almost the same rate another natural area of habitat is degraded or destroyed, a combination that recently led conservation organizations to name Madagascar one of the most important and threatened conservation priorities on the planet. The Natural History of Madagascar provides the most comprehensive, up-to-date synthesis available of this island nation's priceless biological treasures. Contributions by nearly three hundred world-renowned experts cover the history of scientific exploration in Madagascar, its geology and soils, climate, forest ecology, human ecology, marine and coastal ecosystems, plants, invertebrates, fishes, amphibians, reptiles, birds, and mammals. Detailed discussions of conservation efforts in Madagascar highlight several successful park reserve programs that could serve as models for other areas. Beautifully illustrated throughout, the book includes over one hundred color illustrations, with fifty color photos by nature photographer Harald Schütz, as well as more than three hundred black-and-white photographs and line drawings. The Natural History of Madagascar will be the invaluable reference for anyone interested in the Malagasy environment, from biologists and conservationists to policymakers and ecotourists.

This book was released on 2010-07-16 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions. In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Available in PDF, EPUB and Kindle. Book excerpt: In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Pascal Durantel complété ses études agricoles axées sur la protection de la nature par un cycle de biologie à l'université de Clermont-Ferrand. Ensuite, il participe à de nombreux stages centrés sur l'observation du milieu aquatique et effectue plusieurs voyages à l'étranger, notamment en Afrique, pour étudier la flore et recenser les zones humides de certains pays. Il est aujourd'hui responsable de l'iconographie au sein de l'agence Nature. Pierre Enjelvin, après des études de biologie, se spécialise en écologie et hydrobiologie à l'université de Clermont-Ferrand, où un groupe de chercheurs travaille depuis de nombreuses années sur la flore et la faune des eaux douces. Animateur de nombreux stages auprès d'un jeune public, il est actuellement rédacteur scientifique à l'agence Nature et collabore régulièrement à des ouvrages de vulgarisation sur les sciences naturelles. Ce guide d'identification nous permet de découvrir la flore et la faune qui vivent dans les eaux douces (torrents, rivières, lacs, etc.) et les milieux humides (marais, marge des eaux courantes, etc.). Outre l'aspect descriptif d'un ouvrage de détermination, il offre une approche écologique du monde des eaux douces. Après une première partie consacrée à la présentation et au fonctionnement de divers cosystèmes aquatiques, 345 espèces ou genres, liés ou inféodés au milieu aquatique, sont étudiés. Les organismes présentés (végétaux, invertébrés, poissons, amphibiens, reptiles, oiseaux et mammifères) sont ceux que l'on observe le plus souvent dans les pays européens. Chaque espèce ou genre traité fait l'objet d'une monographie dans laquelle on trouve : sa description, sa biologie, son habitat et sa répartition européenne. 280 photographies en couleur et 140 schémas, toujours rapprochés des textes, permettent de visualiser les informations qui y sont contenues. Des conseils pour l'observation dans le milieu naturel, des des de détermination pour les groupes difficiles à identifier, un glossaire des termes scientifiques et un index détaillé facilitent l'emploi de ce guide sur le terrain.
