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 German Federal Agency for Nature Conservation (BfN) initiated a detailed research programme, involving researchers from many renowned German marine research institutes. This book contains the main results of the different projects under this research programme, which formed the basis for the identification and selection of the Natura 2000 sites. Information is given on two NATURA 2000 habitats (sandbanks and reefs), and benthic species, fish, birds and marine mammals, as well as on legal aspects and implementation procedures. Last but not least the book introduces the current status of NATURA 2000 in the German EEZ. Target audience are not only scientists, but also policymakers, environmental organisations and other stakeholders, and the book includes many illustrations.

This book introduces the reader to synthetic or artificial seeds, which refer to alginate encapsulated somatic embryos, vegetative buds or any other micropropagules that can be used as seeds and converted into plantlets after propagating under in vitro or in vivo conditions. Moreover, synthetic seeds retain their potential for regeneration even after low-temperature storage. The production of synthetic or artificial seeds using micropropagules opens up new vistas in agricultural biotechnology. Encapsulated propagules could be used for in vitro regeneration and mass multiplication at reasonable cost. In addition, these propagules may be used for germplasm preservation of elite plant species and the exchange of plant materials between national and international laboratories. This book offers state-of-the-art findings on methods, applications and prospects of synthetic or artificial seeds.

This book places grapes in the context of their family, the Vitaceae. It begins by focusing on the relationship of the family to other angiosperms and the interrelationships and characteristics of its genera. Two chapters emphasize the structure and development of its major vegetative and reproductive characteristics. Keys and illustrated descriptions for 19 North American species including 10 Vitis are provided. The three chapters on Vitis begin with a brief history of grape growing, with emphasis on North America. There is an illustrated life history of grape, following the two-year cycle from bud initiation to fruit maturity. The final chapter discusses the history of grapevine identification in North America, concluding with descriptions and illustrations of 30 important North American cold climate cultivars. The book is a general resource for understanding the growth, development, life history, and identification of grapes and the Vitaceae.

Combining an ecosystems approach with new insights at the molecular and biochemical level, this book presents the latest findings on how plants respond, physiologically, to sulfur in their environment. It explores key areas - such as biotic and abiotic interactions, adaptations to fluctuating supply, and sulfur's role in plant metabolic networks - to assess the functions and implications of this essential plant nutrient in a range of natural, semi-natural and anthropogenic environments.Leaders in the field, Hawkesford and de Kok, draw together an international group of experts in plant sulfur nutrition, to collate and integrate new information from molecular biology, ecology and physiology. The result is an important new reference on the relationships between plants and sulfur at all levels - including contributions arising from recent omic' approaches.

The mosses (Bryophatea, Musci) are a diverse and widely distributed group of land plants. Mosses are attractive experimental plants because they exhibit the traditional attributes of good model systems (Le. ease of growth & maintenance, fast generation time, and amenable genetics) with the added advantage of a haploid gametophyte that allowed developmental mutants to be recovered with relative ease. In addition, mosses with the ability to tolerate extreme environmental conditions offer realistic models for the analysis of environmental stress-tolerance; particularly when compared to tracheophytes such as Arabidopsis thaliana in which these important plant phenotypes are either not clearly expressed or entirely lacking. And, in one of the most exciting developments in Plant Biology, efficient homologous recombination occurs in the moss Physcomitrella patens. The ability to perform efficient homologous recombination (Le. gene knock-outs) in P. patens is at present unique amongst all plants and represents an extremely powerful technique for the functional analysis of many plant genes. Over the past 5 years, a world-wide community of moss researchers has evolved. A highly successful "Moss" conference has been held annually (l998-Mumbai, India; 1999-Carbondale, IL, USA; 2000-Villars, Switzerland; 200l-0kazaki, Japan; 2002-Ambleside, UK; 2003-St. Louis, MO, USA) with "Moss 2004" planned to be held in Frieburg Germany. These conferences have been instrumental in the creation & development of strong collaborative ties, and the free exchange of both ideas and materials.

Global climate change is bound to create a number of abiotic and biotic stresses in the environment, which would affect the overall growth and productivity of plants. Like other living beings, plants have the ability to protect themselves by evolving various mechanisms against stresses, despite being sessile in nature. They manage to withstand extremes of temperature, drought, flooding, salinity, heavy metals, atmospheric pollution, toxic chemicals and a variety of living organisms, especially viruses, bacteria, fungi, nematodes, insects and arachnids and weeds. Incidence of abiotic stresses may alter the plant-pest interactions by enhancing susceptibility of plants to pathogenic organisms. These interactions often change plant response to abiotic stresses. Plant growth regulators modulate plant responses to biotic and abiotic stresses, and regulate their growth and developmental cascades. A number of physiological and molecular processes that act together in a complex regulatory network, further manage these responses. Crosstalk between autophagy and hormones also occurs to develop tolerance in plants towards multiple abiotic stresses. Similarly, biostimulants, in combination with correct agronomic practices, have shown beneficial effects on plant metabolism due to the hormonal activity that stimulates different metabolic pathways. At the same time, they reduce the use of agrochemicals and impart tolerance to biotic and abiotic stress. Further, the use of bio- and nano-fertilizers seem to hold promise to improve the nutrient use efficiency and hence the plant yield under stressful environments. It has also been shown that the seed priming agents impart stress tolerance. Additionally, tolerance or resistance to stress may also be induced by using specific chemical compounds such as polyamines, proline, glycine betaine, hydrogen sulfide, silicon, -aminobutyric acid, -aminobutyric acid and so on. This book discusses the advances in plant performance under stressful conditions. It should be very useful to graduate students, researchers, and scientists in the fields of botanical science, crop science, agriculture, horticulture, ecological and environmental science.

This book describes how genomics has revolutionized our understanding of agriculturally important plant-associated fungi and oomycetes. It illustrates some fundamental discoveries about these eukaryotic microbes with regard to the overall structure of their genomes, their lifestyles and the molecular mechanisms that form the basis of their interactions with plants. Genomics has provided new insights into fungal lifestyles and led to practical advances in plant breeding and crop protection, such as predictions about the spread and evolution of new pathogens.This volume focuses on fungi and oomycetes that are typical dicot plant pathogens and includes: Sclerotinia sclerotiorum, Botrytis cinerea, Alternaria sp.,Verticillium alfalfae and Verticillium dahliae, Fusarium oxysporum, Phytophthora capsici, Phytophthora sojae, Phytophthora ramorum, Phytophthora infestans, Hyaloperonospora arabidopsidis.

Metal toxicity and deficiency are both common abiotic problems faced by plants. While metal contamination around the world is a critical issue, the bioavailability of some essential metals like zinc (Zn) and selenium (Se) can be seriously low in other locations. The list of metals spread in high concentrations in soil, water and air includes several toxic as well as essential elements, such as arsenic (As), cadmium (Cd), chromium (Cr), aluminum (Al), and selenium (Se). The problems for some metals are geographically confined, while for others, they are widespread. For instance, arsenic is an important toxic metalloid whose contamination in Southeast Asia and other parts of world is well documented. Its threats to human health via food consumption have generated immense interest in understanding plants' responses to arsenic stress. Metals constitute crucial components of key enzymes and proteins in plants. They are important for the proper growth and development of plants. In turn, plants serve as sources of essential elements for humans and animals. Studies of their physiological effects on plants metabolism have led to the identification of crucial genes and proteins controlling metal uptake and transport, as well as the sensing and signaling of metal stresses. Plant-Metal Interactions sheds light on the latest development and research in analytical biology with respect to plant physiology. More importantly, it showcases the positive and negative impacts of metals on crop plants growth and productivity.

This book presents studies on current vegetation topics, from polar to tropical regions. It is a festschrift to mark the 70th birthday of Prof. Elgene O. Box, who has studied vegetation all over the world, both through fieldwork and modeling. It reflects a number of his interests, including basic ecological plant forms (cf 'plant functional types'), temperate-zone forests, and evergreen versus seasonal patterns. Section 1 discusses the concept of vegetation series, while Section 2 has two global-scale chapters on plant functional traits and whether they are related more to climate or phylogeny. Section 3 has nine chapters focusing on vegetation history, regional vegetation, and how these have influenced current species organizations and distributions. Regions treated include Russia, China, the USA, Mexico and Mediterranean areas. Lastly, Section 4 addresses aspects of vegetation change and plant ecology. Every chapter in this unique book offers original ideas on the topic of vegetation, as the authors are assembled from a world-wide population of leading vegetational ecologists, whose interests range from local communities to global theoretical questions.

Outside Russia very little is known about the terrestrial ecology, vegetation, biogeographical patterns, and biodiversity of the enormously extensive ecosystems of Yakutia, Siberia. These systems are very special in that they function on top of huge layers of permafrost and are exposed to very severe and extreme weather conditions, the range between winter and summer temperatures being more than 100 degrees C. The soils are generally poor, and human use of the vegetation is usually extensive. Main vegetation zones are taiga and tundra, but Yakutia also supports a special land and vegetation form, caused by permafrost, the alas: more or less extensive grasslands around roundish lakes in taiga. All these vegetation types will be described and their ecology and ecophysiological characteristics will be dealt with. Because of the size of Yakutia, covering several climatic zones, and its extreme position on ecological gradients, Yakutia contains very interesting biogeographical patterns, which also will be described. Our analyses are drawn from many years of research in Yakutia and from a vast body of ecological and other literature in Russian publications and in unpublished local reports. The anthropogenic influence on the ecosystems will be dealt with. This includes the main activities of human interference with nature: forestry, extensive reindeer herding, cattle and horse grazing, etc. Also fire and other prominent ecological factors are dealt with. A very important point is also the very high degree of naturalness that is still extant in Yakutia's main vegetation zones.

This book presents a detailed discussion on the direct interactions of plants and microorganisms in the rhizosphere environment. It includes fifteen chapters, each focusing on a specific component of plant-microbe interactions, such as the influence of plants on the root microbiome, and the downstream effects of rhizosphere microbial dynamics on carbon and nutrient fluxes in the surroundings. As such, the book helps readers gain a better understanding of diversity above the ground, and its effect on the microbiome and its functionality.

Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.

Bambara groundnut (Vigna subterranea) is a crop native to the Bambara tribe of Mali and is grown as a subsistence crop in Africa. Recent advances in research, however, have brought the crop to the forefront of the sustainable agriculture movement. The Bambara plant is highly drought tolerant and rich in protein and carbohydrates, including starch. These macromolecules have enormous industrial potentials. For example, the starch in Bambara grain has been found to exhibit higher (double) viscosity than conventional corn starch. Modified Bambara groundnut starch has been used to produce edible bioplastics that could be upgraded industrially to suit the fourth industrial revolution shift. Bambara plants are also a natural source of soluble fiber, which is gluten-, lactose- and cholesterol-free, with potential as a stabiliser, thickener and gelling agent as well as a cryoprotectant in frozen products. The health benefits include lowering of cholesterol levels, levelling of blood glucose and as a detoxing aid. Furthermore, several researchers have explored the grain either alone or as composite with cereal and tubers for the development of value-added products. Food and Potential Industrial Applications of Bambara Groundnut presents in a clear, coherent way the research findings on Bambara grain and its status as a promising food and industrial crop.

Roots represent half of the plant body and arguably the more interesting half. Despite its obvious importance for the whole plant, until recently our knowledge of the root apparatus was very limited, mostly due to the inadequacy of the techniques available. Recent advances in the visualization and measurement of roots have resulted in significant progress in our understanding of root architecture, growth and behaviour. In this book international experts highlight the most advanced techniques, both lab and field methods, and discuss them in detail. "Measuring Roots" combines academic and practical aspects of this topic, making it a universal handbook for all researchers and others interested in root-measuring methods. "

Triticale crop species has received substantial research support since the mid-20th century making it a commercial success in many countries, in diverse value propositions. However, no recent book captures the new knowledge and progresses made in more than 2 decades. The purpose of this work is to review and collate the new knowledge of triticale plant biology and agronomy, while considering the contribution of biotechnology enablers such as molecular markers, doubled haploid technology and genetic engineering in breeding for traits important for crop production, feed, food and industrial end-uses.

This book provides an up-to-date analysis of the Portuguese forests and forestry sector, including its history, its total economic value, current threats and opportunities and future challenges, namely the need to incorporate more planning and technology in forest management practices. The methodological approach of analysing the forestry sector in terms of its total economic value, and the use of this new perspective to correctly perceive the forest sector and to base development strategies is unique. Also, the use of new methods and technologies in the Portuguese forestry sector will be an opportunity to share these experiences with a wider international audience. For example, fire incidence during the summer has almost no parallel in the Western World, implying that Portuguese forest landscapes function as a "natural lab of wildfires" from which much can be learned globally. Thus, the outcomes of the fire management policies adopted might represent important lessons for Mediterranean basin countries.
