Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet's life systems are involved and dependent on its functioning. Current climate change - global w arming - is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines - Physics, Chemistry, Earth Sciences, Biology, and Sociology - and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth's crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.

This updated volume explores Candida and candidiasis methods, useful to a wide variety of Candida scientists including those new to the field. Beginning with a section on the Candida genome, the book continues by covering techniques for antifungal discovery and studying resistance, pathogenesis and virulence, communities, as well as immunity. Biofilm protocols are also featured. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Candida Species: Methods and Protocols, Second Edition serves as an ideal guide for researchers working to further our understanding of this family of infective fungi.

Stellaris - Plantoids Species Pack

A new, deluxe hardcover edition of one of the most important scientific works ever written In December 1831, Charles Darwin boarded the HMS Beagle, accompanying her crew on a five-year journey that crossed the Atlantic Ocean to survey the coasts of South America. As the expedition's geologist and naturalist, Darwin collected evidence from the Galapagos Islands and other locations which prompted him to speculate that species evolve over generations through a process of natural selection. In 1859, Darwin published On the Origin of Species, a work of scientific literature considered to be the foundation of evolutionary biology. His revolutionary work presented evidence from the Beagle expedition as well as from years of subsequent research and experimentation. Written for non-specialists, Darwin's book gained widespread interest from the scientific community, religious leaders, politicians and the general public. The theory Darwin presented in his book quickly became the subject of heated debate and discussion. Now accepted by the scientific community, Darwin's concepts of evolutionary adaptation via natural selection are central to modern evolutionary theory and form the foundation of modern life sciences. Perhaps the most transformative scientific volume ever published, this volume of the first edition of On the Origin of Species: * Outlines Darwin's ideas, scientific influences and the core of his theory * Details natural selection and address possible objections to the theory * Examines the fossil record and biogeography to support evolutionary adaptation * Features a "Recapitulation and Conclusion" which reviews key concepts and considers the future relevance of Darwin's theory On the Origin of Species: The Science Classic is an important addition to the bestselling Capstone Classics series edited by Tom Butler-Bowdon. It includes an insightful Introduction from leading Darwin scholar Dr John van Wyhe of the University of Singapore, which presents new research and an offers an original perspective on Darwin and his famous work. This high-quality, hardcover volume is a must-have for readers interested in science and scientific literature, particularly evolutionary theory and life sciences.

This textbook offers a detailed overview of the current state of knowledge concerning the ecology and management of compositionally and structurally diverse forests. It provides answers to central questions such as: What are the scientific concepts used to assess the growth, dynamics and functioning of mixed-species forests, how generalizable are they, and what kind of experiments are necessary to develop them further? How do mixed-species stands compare with monocultures in relation to productivity, wood quality, and ecological stability in the face of stress and disturbances? How are the effects of species mixtures on ecosystem functioning influenced by the particular species composition, site conditions, and stand structure? How does any over- or underyielding at the forest-stand level emerge from the tree and organ level, and what are the main mechanisms behind mixing effects? Howcan our current scientific understanding of mixed-species forests be integrated into silvicultural concepts as well as practical forest management and planning? Do the ecological characteristics of mixed-species stands also translate into economic differences between mixtures and monocultures? In addition, the book addresses experimental designs and analytical approaches to study mixed-species forests and provides extensive empirical information, general concepts, models, and management approaches for mixed-species forests. As such, it offers a valuable resource for students, scientists and educators, as well as professional forest planners, managers, and consultants.
