Fossil species appear to persist morphologically unchanged for long intervals of geologic time, punctuated by short bursts of rapid change as explained by the Ecological Evolutionary Units (EEUs). Here, morphological variation in Paleozoic atrypide morphology at the subfamily level (Atrypinae and Variatrypinae) from the Silurian and Devonian time intervals in the third Paleozoic EEU (~444-359 my) were investigated using relatively new techniques of quantitative modeling. The study explains how a group of closely related taxa in atrypide subfamilies exhibit morphological conservation through time in P3 EEU within the Eastern North America region.
Lake Baikal in eastern Siberia is a crucial site for detecting long-term global changes, owing to its high sensitivity to climatic oscillation and its extraordinarily long history. Because lacustrine sediments have an advantage in providing high-resolution information, the sediments in Lake Baikal contain excellent continuous records of past conditions including paleoclimates, evolution, and specification of organisms. Based on the study by the Baikal Drilling Project, this book provides information on global climatic and environmental changes for as much as 12 million years. The book also includes discussions of comparatively short-term changes such as glacial and interglacial transitions that directly link to the present and future environment. Long Continental Records from Lake Baikal summarizes the latest knowledge on the paleoenvironment and provides a foundation for further studies in global environmental changes.
Palaeobiogeography is a complex subject which processes information
provided by both Biology and Earth Sciences. It is conceptually and
philosophically equivalent to neobiogeography. Nevertheless, its
methods are somewhat different, since it is limited by the
incompleteness of the fossil record. On the other hand, it has
direct access to the time dimension, a key ingredient of organic
evolution. Mesozoic benthonic mollusks, and especially bivalves,
have a great potential for palaeobiogeographical analysis due to
their commonly good preservation, abundance, diversity and high
dispersion potential at the larval stage. From a merely descriptive
point of view, the analysis of their distribution shows latitudinal
gradients and distributional patterns, both at regional and global
scales, which are the basis for the recognition of biochoremas or
palaeobiogeographical units of different ranks. Moving forward
towards a causal
This detailed exposition gives background and context to how modern biogeography has got to where it is now. For biogeographers and other researchers interested in biodiversity and the evolution of life on islands, Biogeology: Evolution in a Changing Landscape provides an overview of a large swathe of the globe encompassing Wallacea and the western Pacific. The book contains the full text of the original article explored in each chapter, presented as it appeared on publication. Key features: Holistic treatment, collecting together a series of important biogeographical papers into a single volume Authored by an expert who has spent nearly three decades actively involved in biogeography Describes and interprets a region of exceptional biodiversity and extreme endemism The only book to provide an integrated treatment of Wallacea, Melanesia, New Zealand, the New Zealand Subantarctic Islands and Antarctica Offers a critique of fashionable neo-dispersalist arguments, showing how these still suffer from the same weaknesses of the original Darwinian formulation. The chapters also include analysis of many major theoretical and philosophical issues of modern biogeographic theory, so that those interested in a more philosophical approach will find the book stimulating and thought-provoking.
This is the first truly ecosystem-oriented book on peatlands. It adopts an ecosystems approach to understanding the world's boreal peatlands. The focus is on biogeochemical patterns and processes, production, decomposition, and peat accumulation, and it provides additional information on animal and fungal diversity. A recurring theme is the legacy of boreal peatlands as impressive accumulators of carbon as peat over millennia.
This book fills a gap in knowledge of breaking waves and their influence on the generation of marine fluxes from ocean surfaces. Based on published data as well as on the author's experience, the text explores in detail the relationship chain of breaking waves, whitecaps coverage, rate of wave energy dissipation, amount of aerosol fluxes rising from a given sea basin, and possible seasonal variations.
Recent studies suggest that tropical cyclones are more powerful than in the past with the most dramatic increase in the North Atlantic. The increase is correlated with an increase in ocean temperature. A debate concerns the nature of these increases with some scientists attributing them to a natural climate fluctuation and others suggesting climate change related to anthropogenic increases in forcing from greenhouse gases. A Summit on Hurricanes and Climate Change was held during the spring of 2007 on the island of Crete that brought together leading academics and researchers on both sides of the scientific debate to discuss new research and express opinions about what will happen in the future with regard to hurricane activity. This proceedings volume highlights the state-of-the-science research into various aspects of the hurricane-climate connection. It is likely that the science presented here will lead to new research that will help answer crucial questions about our sustainable future.
The authors of this book are pioneers of the passive, integrative sampling approach and developers of globally applied semipermeable membrane devices (SPMDs). The book will boost understanding of how passive samplers such as SPMD function by examining basic exchange processes that mediate the concentration of SVOCs in a sampling matrix. The book delineates fundamental theory and modeling techniques, while providing a practical guide for its proper application.
This multidisciplinary book covers all aspects of planning, designing, establishing and managing forests and trees and forests in and near urban areas, with chapters by experts in forestry, horticulture, landscape ecology, landscape architecture and even plant pathology. Beginning with historical and conceptual basics, the coverage includes policy, design, implementation and management of forestry for urban populations.
The present volume studies the application of concepts from non-equilibrium thermodynamics to a variety of research topics. Emphasis is on the Maximum Entropy Production (MEP) principle and applications to Geosphere-Biosphere couplings. Written by leading researchers from a wide range of backgrounds, the book presents a first coherent account of an emerging field at the interface of thermodynamics, geophysics and life sciences.
Systematically explores the early origins and basic definition of life. Investigates the major theories of the origins of life in light of modern research with the aim of distinguishing between the necessary and the optional and between deterministic and random influences in the emergence of what we call life. Treats and views life as a cosmic phenomenon whose emergence and driving force should be viewed independently from its Earth-bound natural history. Synthesizes all the fundamental life-related developments in a comprehensive scenario, and makes the argument that understanding life in its broadest context requires a material-independent perspective that identifies its essential fingerprints
This work provides an in-depth perspective and update on special topics in Global Environmental Change in relation to Human Security. It offers an overview of new Joint Projects of the four International Global Change Programmmes and on research efforts in Germany. It is also an up-to-date report on emerging necessities in Global Environmental Change research, and a collection of suggestions for its future evolution.
Wetlands serve many important functions and provide numerous ecological services such as clean water, wildlife habitat, nutrient reduction, and flood control. Wetland science is a relatively young discipline but is a rapidly growing field due to an enhanced understanding of the importance of wetlands and the numerous laws and policies that have been developed to protect these areas. This growth is demonstrated by the creation and growth of the Society of Wetland Scientists which was formed in 1980 and now has a membership of 3,500 people. It is also illustrated by the existence of 2 journals ("Wetlands" and "Wetlands Ecology and Management") devoted entirely to wetlands. To date there has been no practical, comprehensive techniques book centered on wetlands, and written for wetland researchers, students, and managers. This techniques book aims to fill that gap. It is designed to provide an overview of the various methods that have been used or developed by researchers and practitioners to study, monitor, manage, or create wetlands. Including many methods usually found only in the peer-reviewed or gray literature, this 3-volume set fills a major niche for all professionals dealing with wetlands."
No species occurs everywhere. Indeed, the majority are absent from
most places, and where they do occur they are usually quite rare.
Gaston discusses the structure of these distributions - the
structure of the geographic ranges of species.
Group living is a widespread phenomenon amongst animals and has attracted considerable attention in a number of different contexts. This book focuses on the unifying concepts regarding group behaviour that have been developed over the last two decades. The authors discuss the mechanisms that govern the evolution and maintenance of grouping behaviour throughout the animal kingdom, and the factors that control observed group size and group composition in particular situations. Although the book's emphasis is on the elaboration of a conceptual framework, extensive examples and case studies illustrate the diversity of grouping phenomena across taxonomic boundaries, and demonstrate the general applicability of the concepts involved. Living in Groups will familiarize the reader with the latest ideas on the ecology and evolution of group-living animals, providing a summary and critical synthesis of the extensive and diverse literature on the subject.
Palaves biogeographic research over the last twenty years or so has been galvarized by the general acceptance of plate tectonics and, hence, of the orrurrence of continental drift. This study, written by an internationally respected author of palaeontological books from student to professional levels, is the first to synthesize this research. The introductory chapters deal with the historical background, the major factors influencing the distribution of organisms, methods of biogeographic analysis, and the major events of the Phanerozoic. These are followed by concise reviews of the changing terrestrial and marine biogeographic patterns, as indicated by the fossil record, over successive eras, and an attempt to explain the patterns observed. The comprehensive bibliography provided allows readers to follow up material in greater depth. the book is a concise overview of a large body of material, presented in a manner that will be accessible to students and teachers of palaeontology who are interested in biogeography, to geologists who need to know more about the use of fossils in tectonic reconstructions, and to biologists requiring historical insights into the distributions of living organisms.
Geography into the Twenty-first Century brings together teachers from higher and school education to debate the challenges confronting the teaching of geography at the beginning of the new millennium. It presents a collection of edited essays looking at the main developments in the areas of human, physical and environmental geography and the impact of the recent changes in the way that geography is taught in schools, colleges and universities. A particular objective of the book is to examine common issues and objectives which cross the school to higher education divide. Some of the world s leading geographers, including Peter Haggett, Ron Johnston and Tim O Riordan have contributed broad-ranging assessment of how the new research directions and agendas which are revitalising academic geography can be communicated in an exciting and meaningful way to students of all ages. The book also shows how the exacting needs and aspirations of modern geography students and their teachers can revitalise and inspire research endeavours. The fundamental purpose of this timely book is to show how dialogue in geographical education at all levels is essential to the future of a rapidly changing discipline. Rich in ideas, broad in examples and inspiring in its commitment to the improvement of the content and method of geographical education, Geography into the Twenty-first Century is a landmark volume that will be a constant source of reference, guidance and issues for debate for everyone professionally concerned with the teaching of geography. It also provides a unique portrait of a lively discipline at a particularly significant point in its evolution.
The species-area relationship (SAR) describes a range of related phenomena that are fundamental to the study of biogeography, macroecology and community ecology. While the subject of ongoing debate for a century, surprisingly, no previous book has focused specifically on the SAR. This volume addresses this shortfall by providing a synthesis of the development of SAR typologies and theory, as well as empirical research and application to biodiversity conservation problems. It also includes a compilation of recent advances in SAR research, comprising novel SAR-related theories and findings from the leading authors in the field. The chapters feature specific knowledge relating to terrestrial, marine and freshwater realms, ensuring a comprehensive volume relevant to a wide range of fields, with a mix of review and novel material and with clear recommendations for further research and application.
Alexander von Humboldt was the most admired scientist of his day. But the achievements for which he was most celebrated in his lifetime always fell short of perfection. When he climbed the Chimborazo, then believed to be the highest mountain in the world, he did not quite reach the top; he established the existence of the Casiquiare canal, between the great water systems of the Orinoco and the Amazon, but this had been well known to local people; and his magisterial work, Cosmos, was left unfinished. This was no coincidence. Humboldt's pursuit of an all-encompassing, immersive approach to science was a way of finding limits: of nature and of the scientist's own self. A Longing for Wide and Unknown Things portrays a scientific life lived in the era of German Romanticism -- a time of radical change, where the focus on the individual placed a new value on feeling, and the pursuit of personal desires. As Humboldt himself admitted, he 'would have sailed to the remotest South Seas, even if it hadn't fulfilled any scientific purpose whatever'.
This book investigates the spatial distribution of potential temperature-driven malaria transmissions, using the basic reproduction rate (R0) to model the reproduction of the malaria pathogen Plasmodium vivax. The authors mapped areas at risk of an outbreak of tertian malaria in the federal state of Lower Saxony (pre-study) and for whole Germany (main-study) by means of geostatistics for past (1947-2007) and future periods. Projections based on predicted monthly mean air temperature data derived from the IPCC and regionally discriminated by two regional climate models (REMO, WettReg) for the countrywide study.
This book bridges a gap in the literature by bringing together leading specialists from different backgrounds. It addresses the specific need for a readable book on this very interdisciplinary and new topic at research level.
Biogeography has renewed its concepts and methods following important recent advances in phylogenetics, macroecology, and geographic information systems. In parallel, the evolutionary ecology of host-parasite interactions has attracted the interests of numerous studies dealing with life-history traits evolution, community ecology, and evolutionary epidemiology. The Biogeography of Host-Parasite Interactions is the first book to integrate these two fields, using examples from a variety of host-parasite associations in various regions, and across both ecological and evolutionary timescales. Besides a strong theoretical component, there is a bias towards applications, specifically in the fields of historical biogeography, palaeontology, phylogeography, landscape epidemiology, invasion biology, conservation biology, human evolution, and health ecology. A particular emphasis concerns emerging and re-emerging infectious diseases linked to global changes.
Given the fact that there are perhaps 400 billion stars in our Galaxy alone, and perhaps 400 billion galaxies in the Universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials? In this second, significantly revised and expanded edition of his widely popular book, Webb discusses in detail the (for now!) 75 most cogent and intriguing solutions to Fermi's famous paradox: If the numbers strongly point to the existence of extraterrestrial civilizations, why have we found no evidence of them? Reviews from the first edition: "Amidst the plethora of books that treat the possibility of extraterrestrial intelligence, this one by Webb ... is outstanding. ... Each solution is presented in a very logical, interesting, thorough manner with accompanying explanations and notes that the intelligent layperson can understand. Webb digs into the issues ... by considering a very broad set of in-depth solutions that he addresses through an interesting and challenging mode of presentation that stretches the mind. ... An excellent book for anyone who has ever asked 'Are we alone?'." (W. E. Howard III, Choice, March, 2003) "Fifty ideas are presented ... that reveal a clearly reasoned examination of what is known as 'The Fermi Paradox'. ... For anyone who enjoys a good detective story, or using their thinking faculties and stretching the imagination to the limits ... 'Where is everybody' will be enormously informative and entertaining. ... Read this book, and whatever your views are about life elsewhere in the Universe, your appreciation for how special life is here on Earth will be enhanced! A worthy addition to any personal library." (Philip Bridle, BBC Radio, March, 2003) Since gaining a BSc in physics from the University of Bristol and a PhD in theoretical physics from the University of Manchester, Stephen Webb has worked in a variety of universities in the UK. He is a regular contributor to the Yearbook of Astronomy series and has published an undergraduate textbook on distance determination in astronomy and cosmology as well as several popular science books. His interest in the Fermi paradox combines lifelong interests in both science and science fiction.
Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context. Until now biogeography (the study of the geographic distribution of species) and biodiversity (the study of species richness and relative species abundance) have had largely disjunct intellectual histories. In this book, Stephen Hubbell develops a formal mathematical theory that unifies these two fields. When a speciation process is incorporated into Robert H. MacArthur and Edward O. Wilson's now classical theory of island biogeography, the generalized theory predicts the existence of a universal, dimensionless biodiversity number. In the theory, this fundamental biodiversity number, together with the migration or dispersal rate, completely determines the steady-state distribution of species richness and relative species abundance on local to large geographic spatial scales and short-term to evolutionary time scales. Although neutral, Hubbell's theory is nevertheless able to generate many nonobvious, testable, and remarkably accurate quantitative predictions about biodiversity and biogeography. In many ways Hubbell's theory is the ecological analog to the neutral theory of genetic drift in genetics. The unified neutral theory of biogeography and biodiversity should stimulate research in new theoretical and empirical directions by ecologists, evolutionary biologists, and biogeographers. |
