This book covers the latest development in the biotechnological application of extremophiles. Along with this the impact of climate change and environmental pollution on loss of diversity of extremophiles is also discussed. This is crucial as the loss of this diversity is related with the loss of many bioactive compounds and bacteria of ecological importance.

Les populations d’amphibiens sont fortement en déclin mondialement. En plus d’un déclin au niveau des espèces, il y a une perte de la diversité intraspécifique. C’est le cas pour la pédomorphose facultative chez les urodèles. La pédomorphose facultative est un polyphénisme où des individus, les pédomorphes, gardent certains caractères larvaires à l’âge adulte, contrairement aux métamorphes qui se métamorphosent et acquièrent des caractères adaptés à la vie terrestre. Une des raisons expliquant l’existence et le maintien de la pédomorphose facultative est le partage des ressources entre les deux phénotypes. Les populations contenant des pédomorphes se font de plus en plus rares, et l’une des causes est l’introduction d’espèces exotiques dans l’habitat aquatique. Les pédomorphes disparaissent systématiquement des habitats où sont introduits des poissons tandis que les métamorphes subsistent parfois. Le but de ce mémoire était d’étudier l’impact de l’introduction du poisson rouge Carassius auratus sur les populations dimorphiques de tritons palmés Lissotriton helveticus vivant dans des mares au Larzac (France), et d’essayer de comprendre pourquoi les pédomorphes sont plus menacés. L’hypothèse générale était que les poissons modifient la structure de l’habitat et diminuent la richesse spécifique des invertébrés des mares nécessaires à l’alimentation des tritons. L’abondance et la diversité des invertébrés présents dans quatre mares dépourvues de poissons et quatre mares contenant des poissons ont été comparées, ainsi que la structure de leur habitat. Les mares contenant des poissons ne contenaient plus de tritons. L’évolution des communautés d’une mare avant et après l’introduction de poissons a également été suivie. Afin de savoir si le partage des ressources existant entre les métamorphes et pédomorphes était modifié par la présence de poissons, ce qui pourrait être néfaste aux pédomorphes, le régime alimentaire des métamorphes et des pédomorphes a été comparé dans une mare avant et quelques mois après l’introduction de poissons. Le régime alimentaire des tritons métamorphes et pédomorphes de deux mares dépourvues de poissons a également été comparé. La diversité et l’abondance des macro-invertébrés étaient nettement diminuées dans les mares à poissons. La végétation aquatique était absente de ces mares et l’eau, plus trouble, était de couleur verdâtre. Au niveau du zooplancton, les Daphniidae, abondants dans les mares dépourvues de poissons, avaient été remplacés par des Chydoridae dans plusieurs mares à poissons. Dans la mare où des poissons avaient été récemment introduits, l’abondance de plusieurs taxons avait significativement diminué et un taxon relativement abondant avant l’introduction avait disparu. Le régime alimentaire des tritons dimorphiques était significativement différent pour les mares dépourvues de poissons tandis qu’il ne l’était pas dans la mare où des poissons avaient récemment été introduits. Ainsi, il semble que les tritons disparaissent des mares où C. auratus est introduit, notamment parce qu’il provoque une forte diminution des ressources trophiques nécessaires aux tritons. La disparition de la végétation y joue un rôle important. Dans les premiers temps de l’introduction, il est possible que l’introduction des poissons perturbe l’équilibre trophique et diminue le partage des ressources entre les tritons palmés dimorphiques, ce qui serait défavorable aux pédomorphes. Des mesures contre l’introduction de poissons devraient être prises, en particulier dans les zones contenant des pédomorphes. Les poissons introduits devraient également être retirés afin de permettre la résilience des tritons palmés.

Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.

Humans domesticated dogs soon after Neanderthals began to disappear. This alliance between two predator species, Pat Shipman hypothesizes, made possible unprecedented success in hunting large Ice Age mammals—a distinct and ultimately decisive advantage for human invaders at a time when climate change made both humans and Neanderthals vulnerable.

In 1346, a catastrophic plague beset Europe and its neighbours. The Black Death was a human tragedy that abruptly halved entire populations and caused untold suffering, but it also brought about a cultural and economic renewal on a scale never before witnessed. The World the Plague Made is a panoramic history of how the bubonic plague revolutionized labour, trade, and technology and set the stage for Europe's global expansion.0James Belich takes readers across centuries and continents to shed new light on one of history's greatest paradoxes. Why did Europe's dramatic rise begin in the wake of the Black Death? Belich shows how plague doubled the per capita endowment of everything even as it decimated the population. Many more people had disposable incomes. Demand grew for silks, sugar, spices, furs, gold, and slaves. Europe expanded to satisfy that demand-and plague provided the means. Labour scarcity drove more use of waterpower, wind power, and gunpowder. Technologies like water-powered blast furnaces, heavily gunned galleons, and musketry were fast-tracked by plague. A new "crew culture" of "disposable males" emerged to man the guns and galleons.0Setting the rise of Western Europe in global context, Belich demonstrates how the mighty empires of the Middle East and Russia also flourished after the plague, and how European expansion was deeply entangled with the Chinese and other peoples throughout the world.

This succinct book gives an intimate view of the day-to-day functioning of a remarkable river that has figured prominently in history and culture-the Hudson, a main artery connecting New York, America, and the world. Writing for a wide audience, David Strayer distills the large body of scientific information about the river into a non-technical overview of its ecology. Strayer describes the geography and geology of the Hudson and its basin, the properties of water and its movements in the river, water chemistry, and the river's plants and animals. He then takes a more detailed look at the Hudson's ecosystems and each of its major habitats. Strayer also discusses important management challenges facing the river today, including pollution, habitat destruction, overfishing, invasive species, and ecological restoration.
