Animals and plants live in changing environmental conditions which require adaptation in order to cope with this. Some of these environmental changes serve as signals which have to be "sensed" and interpreted correctly by the organisms to initiate the adaptation. This signal processing is based on biochemical, molecular and neuronal processes which are discussed in this book. All examples given underline that continuous adjustment of physiological functions is an essential requirement for life and survival in complex changing environments.

The Biology of Diatoms

William E. Newton

Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.

This inspiring collection of 72 critical and creative contributions honouring the life and work of Desmond Mpilo Tutu comprises a rich and diverse array of reflections on the ecumenical global struggle against Apartheid, and Archbishop Tutu’s role therein, as a political priest, prophet and intellectual. The encounters with ‘the Arch’ and his work has shaped ongoing faith-based, activist and academic pursuits for justice, peace and dignity. Anyone familiar with his outstanding contributions to the promotion of justice, dignity and peace, will know that a hallmark of Desmond Tutu’s celebrated style is his use of narrative and real-life stories. In honour of his unique and remarkable example, the contributions in this book combine oral history and written history paradigms, as well as sociological, philosophical and theological approaches. While the book is meant to be a memorial recollection of encounters with the Arch, the hope is that these recollections will continue to inspire collective struggles and hopes for justice, peace and dignity.

This volume examines the interactions between plants and microorganisms located on plant surfaces, exploring their possible biotechnological applications. Interactions of microbial communities with plants are illustrated by experimental studies of typical symbiosis. Topics include signaling within a symbiosis, molecular differences between symbiotic and pathogenic microorganisms, and the role of microorganisms in the development of plants.
