Events of Increased Biodiversity by Pascal Neige Pdf

The fossil record offers a surprising image: that of evolutionary radiations characterized by intense increases in cash or by the sudden diversification of a single species group, while others stagnate or die out. In a modern world, science carries an often pessimistic message, surrounded by studies of global warming and its effects, extinction crisis, emerging diseases and invasive species. This book fuels frequent "optimism" of the sudden increase in biodiversity by exploring this natural phenomenon. Events of Increased Biodiversity: Evolutionary Radiations in the Fossil Record explores this natural phenomenon of adaptive radiation including its effect on the increase in biodiversity events, their contribution to the changes and limitations in the fossil record, and examines the links between ecology and paleontology’s study of radiation. Details examples of evolutionary radiations Explicitly addresses the effect of adaptation driven by ecological opportunity Examines the link between ecology and paleontology’s study of adaptive radiation

Earth and Life by John A. Talent Pdf

This volume focuses on the broad pattern of increasing biodiversity through time, and recurrent events of minor and major ecosphere reorganization. Intense scrutiny is devoted to the pattern of physical (including isotopic), sedimentary and biotic circumstances through the time intervals during which life crises occurred. These events affected terrestrial, lacustrine and estuarine ecosystems, locally and globally, but have affected continental shelf ecosystems and even deep ocean ecosystems. The pattern of these events is the backdrop against which modelling the pattern of future environmental change needs to be evaluated.

Mars analogs: Environment, Habitability and Biodiversity by Yiliang Li,André Antunes,Maggie CY Lau Vetter,David Flannery Pdf

Martian surface contains diverse lithologies (from sedimentary rocks to mafic-ultramafic igneous rocks) and ground patterns. These rocks record the late-stage evolution on the Martian surface from a temperate environment with bodies of liquid water to the current cold and hyper-arid environment. The constraints on the key parameters and processes for water-rock interaction, sedimentation of materials, and geomorphological development can provide important insights into the environmental change and habitability on the Martian surface. However, due to the difficulty in accessing Martian samples and limited remote-sensing data available from the Martian surface, most of the mysteries on Mars remain unraveled. In this proposed research topic we will focus on geological settings on Earth that are similar to the conditions on Mars. These Mars analogs are employed to infer possible processes on Mars and their impact on habitability and the search for life. The Mars analogs on Earth span a variety of environments, such as the super-arid sedimentary plains (e.g., the Qaidam Basin in the north of the Tibetan Plateau, the Mojave Basin in the USA, and the Atacama Desert in South America), the subsurface fracture waters in Precambrian cratons (e.g., the Canadian Shield, the Fennoscandian Shield, and the Kaapvaal Craton), high salinity localities (e.g. Laguna de Tírez, salt mines, and deep-sea brines) as well as extremely cold and highly radiative environments (e.g., polar regions, thin atmosphere). These settings on Earth are more accessible for collecting high-quality mineralogical, geochemical, geochronological, and microbiological data by the state-of-the-art facilities. These data can provide a solid cornerstone for us to understand the cycles of water and other life-essential elements, and their impact on habitability and biodiversity in extreme environments on Earth as well as the limits of life and the detection of biosignatures. Such research can also provide vital insights on the search for life on other planets and moons.

Biodiversity and Conservation: Causes and consequences of biodiversity loss 2 : pollution, climate change and unsustainable exploitation by Richard J. Ladle Pdf

Although 'biodiversity' is a relatively new coinage, scientists have been studying the subject it describes long before the word's first appearance in the language in the mid-1980s. In 1973, for instance, the UK Systematics Association held a symposium on 'The Changing Flora and Fauna of Britain' which concluded that not enough attention was being paid to the conservation of rarities, a conclusion also reached, said the symposium, at a meeting of the Linnaean Society some forty years earlier. By 1980, the Global 2000 Report to the President published by the US Council on Environmental Quality starkly warned of a diminution of up to one-fifth of all species by the turn of the century, and there is now a growing consensus that the world faces a 'biodiversity crisis' - a potentially catastrophic global loss of genetic, ecosystem, and, most obviously, species diversity. Indeed, especially since the UN Convention on Biological Diversity was promulgated in Rio de Janeiro in 1992, conserving biodiversity has become the principal focus of the global conservation movement. Indeed, the study of the origins, maintenance, and protection of diversity has become perhaps the most vibrant offshoot of ecology and conservation studies. It is increasingly taught and studied in universities - and other research institutions - around the world. Addressing the need for an authoritative reference work to make sense of this rapidly growing subject, and its ever more complex and multidisciplinary corpus of scholarly literature, Biodiversity and Conservation is a new title in the Routledge series, Critical Concepts in the Environment. Edited by Richard Ladle of Oxford University's Centre for the Environment, this new Major Work brings together in five volumes the foundational and the very best cutting-edge scholarship to provide a synoptic view of all the key issues and current debates

The Great Ordovician Biodiversification Event by B. D. Webby Pdf

Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. This is the first book devoted specifically to establishing the global patterns of differentiation of Ordovician biotas through time and space. It provides extensive genus- and species-level diversity data for the many Ordovician fossil groups and presents an evaluation of how each group diversified, with assessments of patterns of change, and rates of origination and extinction.

The Diversity of Life by Edward O. Wilson Pdf

View a collection of videos on Professor Wilson entitled "On the Relation of Science and the Humanities" "In the Amazon Basin the greatest violence sometimes begins as a flicker of light beyond the horizon. There in the perfect bowl of the night sky, untouched by light from any human source, a thunderstorm sends its premonitory signal and begins a slow journey to the observer, who thinks: the world is about to change." Watching from the edge of the Brazilian rain forest, witness to the sort of violence nature visits upon its creatures, Edward O. Wilson reflects on the crucible of evolution, and so begins his remarkable account of how the living world became diverse and how humans are destroying that diversity. Wilson, internationally regarded as the dean of biodiversity studies, conducts us on a tour through time, traces the processes that create new species in bursts of adaptive radiation, and points out the cataclysmic events that have disrupted evolution and diminished global diversity over the past 600 million years. The five enormous natural blows to the planet (such as meteorite strikes and climatic changes) required 10 to 100 million years of evolutionary repair. The sixth great spasm of extinction on earth--caused this time entirely by humans--may be the one that breaks the crucible of life. Wilson identifies this crisis in countless ecosystems around the globe: coral reefs, grasslands, rain forests, and other natural habitats. Drawing on a variety of examples such as the decline of bird populations in the United States, the extinction of many species of freshwater fish in Africa and Asia, and the rapid disappearance of flora and fauna as the rain forests are cut down, he poignantly describes the death throes of the living world's diversity--projected to decline as much as 20 percent by the year 2020. All evidence marshaled here resonates through Wilson's tightly reasoned call for a spirit of stewardship over the world's biological wealth. He makes a plea for specific actions that will enhance rather than diminish not just diversity but the quality of life on earth. Cutting through the tangle of environmental issues that often obscure the real concern, Wilson maintains that the era of confrontation between forces for the preservation of nature and those for economic development is over; he convincingly drives home the point that both aims can, and must, be integrated. Unparalleled in its range and depth, Wilson's masterwork is essential reading for those who care about preserving the world biological variety and ensuring our planet's health.

On the Origins and Dynamics of Biodiversity: the Role of Chance by Alain Pavé Pdf

Chance is necessary for living systems – from the cell to organisms, populations, communities and ecosystems. It is at the heart of their evolution and diversity. Long considered contingent on other factors, chance both produces random events in the environment, and is the product of endogenous mechanisms - molecular as well as cellular, demographic and ecological. This is how living things have been able to diversify themselves and survive on the planet. Chance is not something to which Life has been subjected; it is quite simply necessary for Life. The endogenous mechanisms that bring it about are at once the products and the engines of evolution, and they also produce biodiversity. These internal mechanisms – veritable “biological roulettes” - are analogous to the mechanical devices that bring about “physical chance”. They can be modeled by analogous mathematical equations. This open the way of a global modeling of biodiversity dynamics, but we need also to gather quantitative data in both the laboratory setting as well as in the field. By examining biodiversity at all scales and all levels, this book seeks to evaluate the breadth of our knowledge on this topical subject, to propose an integrated look at living things, to assess the role of chance in its dynamics, in the evolutionary processes and also to imagine practical consequences on the management of living systems.
