Research scientists camped at the desolate McMurdo Dry Valleys of Antarctica studying the local lakes and streams are one day surprised to find a young Weddell seal in their midst. Tired and hungry, and perhaps lured by the smell of the group's cheeseburger dinner, the young male is a long way from his natural habitat on the sea ice of McMurdo Sound. Bound by the Antarctic Conservation Act, the scientists know they cannot provide it with sustenance, but instead contact seal scientists who, after some thought, decide they can provide assistance so the seal can return to the sea ice. The seal gets the ride of its life back to its natural habitat, and the scientists name one of their newly found streams to commemorate their unlikely campmate. Published in cooperation with the Long-Term Ecological Research Network, which is funded by the National Science Foundation.

This second volume in the Long-Term Ecological Research Network Series provides a standardized set of protocols for measuring soil properties. Its goal is to facilitate cross-site synthesis and evaluation of ecosystem processes. It is the first broadly based compendium of methods and will be an invaluable resource for ecologists, agronomists, and soil scientists.

Antarctica is the only major part of the Earth's landmass not directly governed by one nation, but under the control of a treaty, with a multitude of acceding nations. This reference brings together large quantities of information on the wide variety of factors, issues, and individuals influencing and relating to the Antarctic.

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 72. The McMurdo Dry Valleys of southern Victoria Land comprise the largest ice?]free expanse (about 4000 km2) on the Antarctic continent. Research in this region began during British expeditions of the early 1900's and has yielded much information on specific physical, chemical and biological features of the area. Only recently have scientists begun to view the region as an integrated system which includes dynamic interactions among biotic and abiotic components of the environment. The McMurdo Dry Valleys represents the coldest and driest desert on this planet. Photoautotrophic and heterotrophic microorganisms that are intimately linked with the presence of liquid water and nutrients dominate the biological assemblages. Owing to the low average temperature (−20° C) in the region, liquid water is a rare commodity that often exists for a short period only and occurs in many inconspicuous places. It is now clear that the presence of liquid water produces a cascade of tightly coupled events that ultimately leads to the biological production and cycling of organic carbon and related elements. It also is clear that an integrated knowledge of biological, chemical, and physical factors is required to understand biogeochemical dynamics within the cold desert ecosystem of the McMurdo Dry Valleys. While various aspects of this ecosystem have formed the basis of several excellent publications, the compendium of manuscripts published within this volume represents a first attempt to compile complementary information on the abiotic and biotic components of the McMurdo Dry Valleys and link them in a final synthesis chapter.

Mit großer Spannung wurde sie erwartet, auch von Nicht-Katholiken: Die Umwelt-Enzyklika von Papst Franziskus nimmt die heute entscheidenden Themen in den Blick; es geht um die geht um soziale, ökologische und politische Zusammenhänge. Wohl selten war ein päpstliches Schreiben so aktuell und brisant und vor allem relevant für alle Gesellschaftsschichten und Menschen weltweit. Mit "Laudato si" beweist Franziskus, dass die Kirche nach wie vor eine unverzichtbare Stimme im Diskurs zur Gestaltung der modernen Welt ist. Wer verstehen will, wie Papst und Kirche die großen Herausforderungen unserer Zeit bestehen wollen, kommt an diesem Werk nicht vorbei. Ein Muss für jeden, der an den drängenden Fragen unserer Zeit interessiert ist.

Bisher diente biblische Archäologie zum Beweis der Heiligen Schrift. Die beiden international renommierten Archäologen drehen den Spieß um und lassen die Ausgrabungen eine eigene Sprache sprechen. Ihr dramatisch neues, archäologisch fundiertes Bild von der Geschichte Israels zwingt zum Umdenken. Der Auszug aus Ägypten, die Einnahme Kanaans, das Großreich unter König David und der Tempelbau in Jerusalem unter König Salomon galten lange auch bei den kritischsten Wissenschaftlern als gesichert. Neueste Ausgrabungen, bisher nur Experten bekannt, zeigen ein ganz anderes Bild: " Den Auszug aus Ägypten gab es ebensowenig wie eine "Landnahme". " Jerusalem unter David und Salomon war ein größeres Dorf sicher ohne zentralen Tempel und großen Palast. " Der Monotheismus hat sich viel später entwickelt als bisher angenommen & Das klar und anschaulich geschriebene Buch ist in zwölf Kapitel gegliedert: Auf die Nacherzählung der biblischen Geschichte folgt jeweils die archäologische Spurensuche. Im nächsten Schritt rekonstruieren die Autoren (Israel Finkelstein ist der Direktor des israelischen Instituts Tel Aviv) den tatsächlichen historischen Ablauf, um abschließend zu fragen, wann und warum die Geschichte aufgeschrieben wurde.
