The Ecotoxicology of Aquatic Macrophytes (Environmental Contamination Remediation and Management)

by Mirta L. Menone Chris D. Metcalfe

This book focuses on the topic of ecotoxicology of aquatic macrophytes and is wide ranging, including the use of macrophytes for remediation of contaminated sites. Many human activities are threats to the equilibrium of natural ecosystems. Pollution from point and non-point sources can be assessed using a variety of techniques, such as biomonitoring, biomarkers and biosensors. In aquatic ecosystems, biomonitoring of pollutants is mostly conducted by analysis of the tissues of invertebrates and fishes, and biomarker studies are also more widely applied to animals rather than in plants. Aquatic macrophytes occupy a key niche in aquatic ecosystems and provide a range of ecosystem services. In addition to their role in primary production, vegetation plays a key role in the cycling and retention of nutrients and generally acts as a sink for pollutants. Therefore, because of their importance to aquatic ecosystems, more attention should be paid to understanding the fate of pollutants and to developing methods to evaluate the health status of macrophytic plants in freshwater, marine and estuarine environments.

The Ecphoras: Iconic Fossils of Eastern North America

by Edward J. Petuch David P. Berschauer

In the Miocene and Pliocene fossil shell beds of the eastern United States, the single most spectacular molluscan species radiation is seen in the ecphora shells (the Tribe Ecphorini). These bizarrely shaped gastropods, with their distinctive ribbed shell sculpture, represent a separate branch of the Subfamily Ocenebridae, Family Muricidae. Characteristically, these muricid gastropods are heavily ornamented with spiral ribs and cords and are considered some of the most beautiful and interesting groups of fossil mollusks found along the Atlantic Coastal Plain and Floridian Peninsula. The ecphoras are greatly sought after by fossil collectors. The ecphora faunas, and their individual species and subspecies, are illustrated and described in detail, along with photographs of ecphora-bearing geological units and in-situ specimens. The authors list the 67 known species and subspecies that are recognized as valid, arranged by the eight genera and five subgenera that encompass these taxa.

La ecuación de Dios: La búsqueda de una teoría del todo

by Michio Kaku

La búsqueda del santo grial de la ciencia por el reputado físico teórico Michio Kaku. Cuando Newton formuló la ley de la gravedad, unificó las reglas que rigen los cielos y la Tierra. Hoy el mayor desafío de la física es encontrar una síntesis de las dos grandes teorías, basadas en principios matemáticos diferentes: la de la relatividad y la cuántica. Combinarlas sería el mayor logro de la ciencia, una profunda fusión de todas las fuerzas de la naturaleza en una hermosa y magnífica ecuación que nos permitiría comprender los misterios más profundos del universo: ¿qué sucedió antes del Big Bang? ¿Qué hay al otro lado de un agujero negro? ¿Existen otros universos y otras dimensiones? ¿Es posible viajar en el tiempo? Con ese objetivo, y con su conocida capacidad para divulgar conceptos complejos en un lenguaje accesible y atrayente, Michio Kaku repasa la historia de la física hasta llegar a los debates actuales en torno a la búsqueda de esa teoría unificadora, la «ecuación de Dios». Una historia cautivadora y contada de manera magistral, en la que lo que está en juego es nada menos que nuestra concepción del universo. La crítica ha dicho:«Si hay alguien capaz de desmitificar las matemáticas esotéricas y la física de la teoría de cuerdas, es Kaku. Y precisamente eso hace en este maravilloso librito, que prepara a los lectores para el próximo gran avance».The Wall Street Journal «Este libro capta la fascinante y misteriosa belleza del universo, de nuestro planeta y de nosotros mismos, y cautivará a cualquiera que reflexione sobre nuestra existencia».Booklist «Deslumbrante. La habilidad de Kaku de hacer inteligibles conceptos difíciles de concebir hace de este libro una verdadera revelación intelectual».Publishers Weekly «Convincente y accesible».Nature «Kaku escribe con un lenguaje claro y conciso. Una historia accesible y atractiva de una compleja búsqueda científica».Smithsonian Review

Edelsteine

by Florian Neukirchen

Wie entstehen Edelsteine? Wo gibt es sie? Und was können wir von ihnen lernen? Bei der Bildung von Smaragd, Rubin, Diamant, Topas oder Opal sind die beteiligten Zutaten und Prozesse so vielfältig wie die Edelsteine selbst. Während beispielsweise die Riesenkristalle eines Pegmatits innerhalb von Tagen wachsen, dauert die Entstehung von Amethystgeoden einige Millionen Jahre. Anschaulich erklärt Florian Neukirchen, wie seltene Elemente angereichert werden und wie es zu ungewöhnlichen Begegnungen zwischen Spurenelementen kommt. Diamanten verdanken wir nicht nur einiges Wissen über den Erdmantel, sondern auch über die Entstehung der ersten Kontinente. Bei ihrer Bildung spielen Redoxreaktionen im Erdmantel eine ähnlich wichtige Rolle wie ungewöhnlich ablaufende Vulkaneruptionen, durch die sie sicher an die Oberfläche gebracht werden, ohne zu verbrennen. Edelsteine erzählen uns manch erstaunliche Geschichte: Wie eine Kapsel, die geheime Dokumente birgt, enthalten sie Informationen über unzugängliche Regionen der Erde aus einer fernen Vergangenheit und sogar aus der Tiefe des Weltalls: In Meteoriten wurden Diamanten gefunden, die sogar älter als das Sonnensystem sind. Granate dienen Forschern als eine Art Thermometer, da sie die Bildungstemperatur eines Gesteins anzeigen. Einige Zirkonkristalle sind die einzigen Zeugen aus der höllisch heißen Frühzeit der Erde, aus der keine Gesteine erhalten sind. Die winzigen Kristalle ermöglichen uns sogar Aussagen über das damalige Klima. Abgerundet wird das Buch mit Informationen über Minen, Märkte und antike Handelsrouten und einem Kapitel über die technische Anwendung und synthetische Herstellung von Edelsteinen.
