Das Recht der Entwicklungslander auf Entwicklung und die Erhaltung der naturlichen Lebensgrundlagen sind die wesentlichen Herausforderungen bei einer Energiewende zur Nachhaltigkeit und der Ausgangspunkt des vorliegenden Gutachtens. Wenn die Politik sofort entschieden handelt, ist die Transformation der globalen Energiesysteme ohne gravierende Einschrankungen moglich und finanzierbar: Die Energieeffizienz muss gesteigert, der Anteil fossiler Energietrager deutlich verringert und die erneuerbaren Energien massiv gefordert werden. Fur den Einstieg in das Solarzeitalter hat der...

Terrestrial carbon balance is uncertain at the regional and global scale. A significant source of variability in mid-latitude ecosystems is related to the timing and duration of phenological phases. Spring phenology, in particular, has disproportionate effects on the annual carbon balance. However, the traditional phenological indices that are based on leaf-out and flowering times of select indicator species are not universally amenable for predicting the temporal dynamics of ecosystem carbon and water exchange.

Phenology of Ecosystem Processes evaluates...

This volume offers insight in the identification and selection procedure of marine protected areas in the German exclusive economic zones (EEZs) of the North - and Baltic Seas. EU Member States are obliged to establish a coherent network of protected areas, consisting of sites identified under the EC Habitats and Birds Directives. The goal of this Natura 2000 network is the conservation of biodiversity on land and in the sea. To fill important gaps in knowledge regarding the presence, abundance, and distribution of certain species and habitats in the German North- and Baltic Seas, the...

In the present volume taxonomic treatments including descriptions of and keys to the families and genera for the orders Santalales and Balanophorales are offered, the former group here comprising 12 families with 162 genera and about 2100 species, and the latter with the single family Balanophoraceae composed of 16 genera and about 42 species. The contentious family classification of Santalales has been thoroughly revised against the background of previous classifications as well as available structural and molecular evidence, and also the classification of Balanophoraceae has been...

The range is diverse and spectacular; and whether distant, offshore, inhabited, uninhabited, tropical or polar, each is a unique self-contained habitat with a...

This textbook is for the standard, one-semester, junior-senior course that often goes by the title "Elementary Partial Differential Equations" or "Boundary Value Problems." The audience consists of students in mathematics, engineering, and the sciences. The topics include derivations of some of the standard models of mathematical physics and methods for solving those equations on unbounded and bounded domains, and applications of PDE's to biology. The text differs from other texts in its brevity; yet it provides coverage of the main topics usually studied in the standard course, as well as...

Plants use resources, i.e. carbon, nutrients, water and energy, either for growth or to defend themselves from biotic and abiotic stresses. This volume provides a timely understanding of resource allocation and its regulation in plants, linking the molecular with biochemical and physiological-level processes. Ecological scenarios covered include competitors, pathogens, herbivores, mycorrhizae, soil microorganisms, carbon dioxide/ozone regimes, nitrogen and light availabilities. The validity of the "Growth-Differentiation Balance Hypothesis" is examined and novel theoretical concepts and...

The annual Evolutionary Biology Meetings in Marseilles serve to gather leading evolutionary biologists and other scientists using evolutionary biology concepts, e.g. for medical research. The aims of these meetings are to promote the exchange of ideas and to encourage interdisciplinary collaborations.

This book collects 19 selected contributions presented at the 15^th meeting, which took place in September 2011. It starts with a description of the life and work of J.B.S. Haldane, a remarkable evolutionary biologist of the 20^th century. The remaining...

People have relied on medicinal products derived from natural sources for millennia, and animals have long been an important part of that repertoire; nearly all cultures, from ancient times to the present, have used animals as a source of medicine. Ingredients derived from wild animals are not only widely used in traditional remedies, but are also increasingly valued as raw materials in the preparation of modern medicines. Regrettably, the unsustainable use of plants and animals in traditional medicine is recognized as a threat to wildlife conservation, as a result of which discussions...
