Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems. Written for: All who are interested in parthenogenesis and evolutionary biology, including undergraduate and graduate students and senior researchers

Various parallels have been drawn between wolves and humans from the perspective of their social organisation. Therefore, studying wolves may well shed light on the evolutionary origins of complex human cognition and, in particular, on the role that cooperation played in its development. Humans closely share their lives with millions of dogs - the domesticated form of wolves. Biologically, wolves and dogs can be considered to be the same species; yet only dogs are suitable living companions in human homes, highlighting the importance of cognitive and emotional differences between the two forms. The behaviour of wolves and dogs largely depends on the environment the animals grew up and live in. This book reviews more than 50 years of research on the differences and similarities of wolves and dogs. Beyond the socio-ecology, the work explores different theories about when and how the domestication of wolves might have started and which behaviours and cognitive abilities might have changed during this process. Readers will discover how these fascinating animals live with their conspecifics in their social groups, how they approach and solve problems in their daily lives and how they see and interact with their human partners.

Microbes play a major role in the degradation of various pollutants. Therefore, microbes find potential application in the area of energy and environmental technology. The book provides in-depth literature on the topics of environmental and industrial importance. It is compiled to explore the application of microbe used in the degradation of aflatoxin, polymers, biomass into fuel, disinfectants, food products, xenobiotic compounds, lipids, steroids, organic pollutants, proteins, oil waste, and wastewater pollutants. This book will be of interest to teachers, researchers, scientists, and capacity builders. Also, the book serves as additional reading material for undergraduate and graduate students of microbiology and environmental sciences. National and international remediation and restoration scientists, policymakers will also find this to be a useful read.

The ten-year research program and the Kapalga fire experiment at CSIRO in Australia has provided a wealth of knowledge about savanna ecosystems and the critical but poorly understood role of fire. The frequent low intensity fires examined in this volume characterize fire in the tropics and are a dominant force in shaping the structure and function of tropical ecosystems. Contributors discuss fire in relation to rainfall, groundwater, and the mammals and plants in the ecology and management of ecosystems. Among the management issues addressed are: habitat management, endangered species, protection of people and property, erosion and nutrient depletion, integration of knowledge from indigenous people and western science, and atmospheric pollution from fire smoke. This book will be valuable to tropical and savanna ecologists, fire ecologists and fire managers throughout the world, whether they are interested in plants, animals, soils or in the landscape as a whole.

Endophytes are commonly known as microorganisms, mainly bacteria and fungi, which live inside plant tissues without inducing symptoms. Considering the long-lived trees, endophytes have a fundamental role in preparing their hosts to face extreme weather conditions, drought, heat, cold, and pathogen and herbivore attacks. The current knowledge clearly demonstrates the importance of endophytes in shaping the plant diversity in a forest. Endophytes have an important capacity for biocontrol of forest diseases. Considering endophyte diversity and the range of various compounds and enzymes they can produce, endophytes can be used for various biotechnological applications.

The rhizosphere is a very complex environment in which the effects of the plant on soil microorganisms and the effects of the microorganisms on the plant are interacting and are interdependent. Plant root exudates and breakdownproducts attract microbes and feed them and, in turn, the plants often bene't from the microbes. Interactions among microorg- ismsandplantrootsareessentialfornutritionalrequirementsoftheplant. Plant growth, development and productivity are largely dependent on the soil environment in the root region rhizosphere. The new techniques of studying the rhizosphere enables us to get a much better understanding of the dynamics of the rhizosphere population, such rhizosphere studies beingofinteresttoagriculturists, soilbiologists, chemists, microbiologists andmolecularbiologists. The rhizosphere microbes in?uence the root environment in several ways. They may change the oxidation-reduction potential, in?uence the availabilityofmoistureandnutrients, producegrowthinhibitingorgrowth promoting substances in the form of exudates, provide competition and possiblyinducemanyothereffects.Mycorrhizalassociationsarebene?cial in mineral uptake and in increasing root surface area for effective ion absorption. Antagonism, competitionandsynergisminsoilandtherhizoplane(r- zosphere) are the most important microbial interactions to consider in the study of rhizosphere biology. With the growing information on the production of growth regulators, competitiveness of the microbes in the rhizosphere, microsymbionts, and other factors, their effect upon plant growth will become more evident. Experiments on the introduction of microbes or their products in the rhizosphere will help to improve our understandingofthebiologyoftherhizosp

This is a synthesis of several studies on fluxes of carbon, water and energy conducted in a range of European forests encompassing different climates, soils and biomes. The volume covers methodological issues, particularly the eddy covariance technique describing its limitations and practical use. Further, major insights in ecosystem processes gained through investigations in evergreen coniferous, mediterranean and broad-leaved forests are presented. In an integrated effort, atmospheric physicists, ecologists, ecosystem modellers, and remote sensing scientists elucidate the impact of terrestrial ecosystems on the global biogeochemistry of the earth.

Phylogenetic comparative approaches are powerful analytical tools for making evolutionary inferences from interspecific data and phylogenies. The phylogenetic toolkit available to evolutionary biologists is currently growing at an incredible speed, but most methodological papers are published in the specialized statistical literature and many are incomprehensible for the user community. This textbook provides an overview of several newly developed phylogenetic comparative methods that allow to investigate a broad array of questions on how phenotypic characters evolve along the branches of phylogeny and how such mechanisms shape complex animal communities and interspecific interactions. The individual chapters were written by the leading experts in the field and using a language that is accessible for practicing evolutionary biologists. The authors carefully explain the philosophy behind different methodologies and provide pointers - mostly using a dynamically developing online interface - on how these methods can be implemented in practice. These "conceptual" and "practical" materials are essential for expanding the qualification of both students and scientists, but also offer a valuable resource for educators. Another value of the book are the accompanying online resources (available at: http://www.mpcm-evolution.com), where the authors post and permanently update practical materials to help embed methods into practice.

'A funny and beautifully written welcome to the enigmatic, weird and wonderful world of wasps' DAVE GOULSON, author of SILENT EARTH There may be no insect with a worse reputation than the wasp, and none guarding so many undiscovered wonders. Where bees and ants have long been the darlings of the insect world, wasps are much older, cleverer and more diverse. They are the bee's evolutionary ancestors - flying 100 million years earlier - and today they are just as essential for the survival of our environment. A bee, ecologist Professor Seirian Sumner argues, is just a wasp that has forgotten how to hunt. For readers of Entangled Life, Other Minds and The Gospel of Eels, this is a book to upturn your expectations about one overlooked animal and the wider architecture of our natural world. With endless surprises, this book might teach you about the wasps that spend their entire lives sealed inside a fig, about stinging wasps, about parasitic wasps, about wasps that turn cockroaches into living zombies, about how wasps taught us to make paper. It offers up a maligned insect in all its diverse, unexpected splendour; as both predator and pollinator, the wasp is an essential pest controller worldwide. Inside their sophisticated social worlds is the best model we have for the earth's major evolutionary transitions. In their understudied biology are clues to progressing medicine, including a possible cure for cancer. The closer you look at these spurned, winged insects - both custodians and bouncers of our planet - the more you see. Their secrets have so far gone mostly untapped, but the potential of the wasp is endless.

The present volume includes a representative selection of fully refereed papers as well as a complete list of all the contributions which were presented at the meeting. Reviews of selected topics as well as original experimental data are included. The book provides valuable information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms. "

The aim of this book is to systematize and discuss population genetic studies of freshwater fish in a region that harbors the greatest diversity of species among all inland water ecosystems. This volume explores the genetic evaluation for a number of orders, families and species of Neotropical fishes, and provides an overview on genetic resources and diversity and their relationships with fish domestication, breeding, and food production.

The Antarctic provides a suite of scenarios useful for investigating the range of climate change effects on terrestrial and limnetic biota. The international SCAR programme RiSCC (Regional Sensitivity to Climate Change in Antarctic Terrestrial and Limnetic Ecosystems) is investigating these scenarios with the goals of (1) understanding the likely response of Antarctic biota to changing climates, and (2) contributing to the development of broadly applicable theory concerning interactions between climate change, indigenous and introduced species, and ecosystem functioning. The programme draws upon both new and existing data.

The purpose of the book is to provide, based on the most up to date knowledge, a synthesis of the likely effects of climate change on Antarctic terrestrial and limnetic ecosystems and, thereby, to contribute to their management and conservation, based on the information.

"The book is described as "a milestone as it has collected the most actual facts about the Antarctic region and allows us to look at the phenomenon from physical and biological perspectives. It is a 'must' for all who are concerned about our environment." SCAR newsletter: Issue 10, April 2007

This edited volume provides a variety of insights into the context in which ocean and wetlands policy is placed at the sub-continental level. The governments of Mexico, Canada, and United States of America have recognized the importance of conserving, protecting, and enhancing the environment in their territories. As a result, they have developed an institutional structure aimed at furthering environmental cooperation. However, marine environment has played a secondary role, characterized by scientific cooperation that does not develop into regional policies. This project analyzes how ocean and wetlands preservation is omitted from the North American Agreement on Environmental Cooperation, meaning that collaborative efforts under-perform or remain largely sidelined from mainstream issues. As contributors come from a mix of the social and natural sciences (politics, international relations, law studies, sociology, oceanology, and oceanography), this book presents diverse viewpoints on how to address wetlands protection, deep ocean research collaboration, and the marine context of the Sustainable Development Goals.

'Defending Life' discusses the relationship between hosts and parasites. It contains detailed descriptions of the immune system and the microbial world as well as methodological and conceptual clarifications. Its emphasis on analytical abstractions, coherent patterns and generative mechanisms makes possible the distinction between genuine causality and coincidental associations and increases the understanding of why we observe what we observe.A major contention of the book is that the immune system depends ontologically on the ecosystem in which it is embedded; it would not have the features it has if it was not related in one way or other to parasitic agents and to the host's own cells and tissues. To sustain this argument, the book investigates life at all layers, from molecules up through cells, organisms and ecosystems.

Biological systems are regulated by the thermodynamic parameters of pressure and temperature. With the help of new spectroscopic methods it is now possible to study the structure and function of such systems under extreme pressures and temperatures. This book described the resulting theory and applications of these pressure and temperature effects. The subjects covered include the use of high pressure in food processing and even the theory of the origin and evolution of life. Readers exploring the world of biology in extreme environments will find this book particularly useful.

With one volume each year, this series keeps scientists and advanced students informed of the latest developments and results in all areas of the plant sciences. This latest volume includes reviews on plant physiology, biochemistry, genetics and genomics, forests, and ecosystems.

Carbon Sequestration in Forest Ecosystems is a comprehensive book describing the basic processes of carbon dynamics in forest ecosystems, their contribution to carbon sequestration and implications for mitigating abrupt climate change. This book provides the information on processes, factors and causes influencing carbon sequestration in forest ecosystems. Drawing upon most up-to-date references, this book summarizes the current understanding of carbon sequestration processes in forest ecosystems while identifying knowledge gaps for future research, Thus, this book is a valuable knowledge source for students, scientists, forest managers and policy makers.

Carbonate sediments are of increasing relevance for archives of past environmental conditions and for economical reasons in areas of geothermal energy and hydrocarbon reservoirs. Complex interaction of physical and chemical parameters with biological parameters determines the architecture and composition of carbonate sedimentary bodies. This book closes some of the still existing gaps in our understanding of the influence and interplay of physical, chemical, and biological parameters with carbonate sedimentation. An understanding of this interaction is not only required for reliable prediction of reservoir quality but also for a robust interpretation of environmental conditions in the past and the present. It is written by geologists for geologists in order to provide an easily accessible overview of the large amount of relevant information provided by the neighbouring sciences. The approach of the book is to document the modern depositional environments of three classical areas of carbonate deposition, each characteristic for a specific sedimentological setting (isolated platform, attached shelf, ramp) in order to assess both the range of physical, biological and chemical parameters and their sedimentary response. This book presents a comprehensive compilation based on data from published work and unpublished theses, and the integration of these data in order to extract previously undiscovered relationships between the discussed parameters and carbonate deposition.

The adverse consequences of pollution impact on terrestrial ecosystems have been under careful investigation since the beginning of the twentieth century. Several thousand case studies have documented the biotic effects occurring in contaminated areas. However, after more than a century of research, ecologists are still far from understanding the effects of pollution on biota. Only a few generalisations have been made on the basis of extensive monitoring programs and numerous expe- ments with industrial contaminants. The need to reveal general patterns in the responses of terrestrial biota to ind- trial pollution and to identify the sources of variation in these responses became obvious more than a decade ago. At about that time, our team initiated a quanti- tive research synthesis of the biotic effects caused by industrial pollution, based on 1 a meta-analysis of published data. All meta-analyses conducted so far (covering diversity and abundance of soil microfungi, diversity of vascular plants, diversity and abundance of terrestrial arthropods, and plant growth and reproduction) c- sistently showed high heterogeneity in the responses of terrestrial biota to industrial pollution. At the same time, they demonstrated an unexpected shortage of infor- tion suitable for meta-analyses, as well as a considerable influence of methodology of primary studies on the outcome of the research syntheses. To overcome the identified problems, we designed a comparative study, the results of which are reported in this book.

Over the past decade the scientific activities of the Joint Global Ocean Flux Study (JGOFS), which focuses on the role of the oceans in controlling climate change via the transport and storage of greenhouse gases and organic matter, have led to an increased interest in the study of the biogeochemistry of organic matter. There is also a growing interest in global climate fluctuations. This, and the need for a precise assessment of the dynamics of carbon and other bio-elements, has led to a demand for an improved understanding of biogeochemical processes and the chemical characteristics of both particulate and dissolved organic matter in the ocean. A large amount of proxy data has been published describing the changes of the oceanic environment, but qualitative and quantitative estimates of the vertical flux of (proxy) organic compounds have not been well documented. There is thus an urgent need to pursue this line of study and, to this end, this book starts with several papers dealing with the primary production of organic matter in the upper ocean. Thereafter, the book goes on to follow the flux and characterization of particulate organic matter, discussed in relation to the primary production in the euphotic zone and resuspension in the deep waters, including the vertical flux of proxy organic compounds. It goes on to explain the decomposition and transformation of organic matter in the ocean environment due to photochemical and biological agents, and the reactivity of bulk and specific organic compounds, including the air-sea interaction of biogenic gases. The 22 papers in the book reflect the interests of JGOFS and will thus serve as a valuable reference source for future biogeochemical investigations of both bio-elements and organic matter in seawater, clarifying the role of the ocean in global climate change.
