This work gives a critical overview on the evolution and population biology of salmon and their relatives. It should appeal to investigators in each of the scientific disciplines it integrates - evolutionary biology, ecology, salmonid biology, management and conservation. Variation in salmonids can be used to illustrate virtually all evolution.
This “superb history” of artificial light traces the evolution of society—“invariably fascinating and often original . . . [it] amply lives up to its title” (Publishers Weekly, starred review). In Brilliant, Jane Brox explores humankind’s ever-changing relationship to artificial light, from the stone lamps of the Pleistocene to the LEDs embedded in fabrics of the future. More than a survey of technological development, this sweeping history reveals how artificial light changed our world, and how those social and cultural changes in turn led to the pursuit of more ways of spreading, maintaining, and controlling light. Brox plumbs the class implications of light—who had it, who didn’t—through the centuries when crude lamps and tallow candles constricted waking hours. She identifies the pursuit of whale oil as the first time the need for light thrust us toward an environmental tipping point. Only decades later, gas street lights opened up the evening hours to leisure, which changed the ways we live and sleep and the world’s ecosystems. Edison’s bulbs produced a light that seemed to its users all but divorced from human effort or cost. And yet, as Brox’s informative portrait of our current grid system shows, the cost is ever with us. Brilliant is infused with human voices, startling insights, and timely questions about how our future lives will be shaped by light
In recent years, scientists have realized that evolution can occur on timescales much shorter than the "long lapse of ages" emphasized by Darwin—in fact, evolutionary change is occurring all around us all the time. This book provides an authoritative and accessible introduction to eco-evolutionary dynamics, a cutting-edge new field that seeks to unify evolution and ecology into a common conceptual framework focusing on rapid and dynamic environmental and evolutionary change. Andrew Hendry covers key aspects of evolution, ecology, and their interactions. Topics range from natural selection, adaptive divergence, ecological speciation, and gene flow to population and community dynamics, ecosystem function, plasticity, and genomics. Hendry evaluates conceptual and methodological approaches, and draws on empirical data from natural populations—including those in human-disturbed environments—to tackle a number of classic and emerging research questions. He also discusses exciting new directions for future research at the intersection of ecology and evolution. An invaluable guide for students and researchers alike, Eco-evolutionary Dynamics reveals how evolution and ecology interact strongly on short timescales to shape the world we see around us.
Everyone wonders what tomorrow holds, but what will the real future look like? Not decades or even hundreds of years from now, but thousands or millions of years into the future. Will our species change radically? Or will we become builders of the next dominant intelligence on Earth- the machine? These and other seemingly fantastic scenarios are the very possible realities explored in Peter Ward's Future Evolution, a penetrating look at what might come next in the history of the planet. Looking to the past for clues about the future, Ward describes how the main catalyst for evolutionary change has historically been mass extinction. While many scientist direly predict that humanity will eventually create such a situation, Ward argues that one is already well underway--the extinction of large mammals--and that a new Age of Humanity is coming that will radically revise the diversity of life on Earth. Finally, Ward examines the question of human extinction and reaches the startling conclusion that the likeliest scenario is not our imminent demise but long term survival--perhaps reaching as far as the death of the Sun! Full of Alexis Rockman's breathtaking color images of what animals, plants and other organisms might look like thousands and millions of years from now, Future Evolution takes readers on an incredible journey through time from the deep past into the far future.
Diatoms are the most species rich group of algae, and they contribute about 20% of annual global carbon fixation. They play major roles in ocean food webs and global biogeochemical cycles. They are also a target of the biotechnology industry because of their nano-patterned silica cell wall and high lipid content. Diatoms have received increasing attention as more genomes became available and because of the development of genome editing tools such as the CRISPR/Cas9 technology, which has made diatoms as genetically tractable as well-established biological model species. This book provides an overview on diatom molecular biology. It brings together international leading experts in the field to discuss the latest data and developments from genes to ecosystems. As the understanding of diatoms is currently experiencing a step change, it is critical to allow for synergistic approaches on diverse aspects of diatom biology and evolution. The books offers fundamental insights into the molecular life of diatoms; at the same time new scientific concepts are developed based on the application of the latest molecular tools and genomic information to explore the fascinating lifestyle of diatoms.
The theme of this volume is to discuss Eco-evolutionary Dynamics. - Updates and informs the reader on the latest research findings - Written by leading experts in the field - Highlights areas for future investigation
Zusammenfassung: This volume provides in depth reviews of the protein targeting translocation processes, gene transfer processes and genome reduction processes in the host and in the endosymbiont which were likely utilized during the evolution of an endosymbiont into mitochondria, mitochondria related organelles, simple and complex chloroplasts. These reviews cover both the current understanding of the host processes as well as the evolutionary outcomes used by these organelles for protein targeting and translocation. Reviews of the current knowledge of these topics are plentiful but scattered throughout the bacterial, parasite, plant and animal literature; here, reviews of current knowledge with evolutionary outcomes and future perspectives, written by leading researchers in their respective areas, are united into one comprehensive volume, essential for students and scientists interested in or working on subcellular protein localization, protein targeting signals, translocation of proteins across and insertion into membranes, nucleic acid transfer between genomes, genome reduction and evolution of mitochondria and chloroplast.
Fishes are by far the most species-rich vertebrate taxon, and it is also the vertebrate group with the most strikingly diverse repertoire of behaviours and behavioural adaptations. As such, they provide us with many opportunities to explore the fascinating complexities of animal behaviour. Central questions addressed in this book include: How do se
With the decline in world fish stocks, our knowledge of fish reproduction has become fundamental. Reproduction is an essential commitment to future generation. It is also a continuous development process throughout ontogeny, requiring energetic, ecological, physiological, anatomical, biochemical and endrocrinological adaptations. The first chapters highlight important issues affecting fish normal ways of reproductive development; details would focus on species living in opposite environments, such as tropical and polar fishes; far related, as teleosts and cartilaginous fishes; and finally, fish having different reproductive strategies. Thereafter, since many fishes live in detrimental environments, mainly induced by the continuous input of xenobiotic substances into waterways, the authors found it highly pertinent to include this topic. Herein, the authors fix their attention on the factors and mechanisms that may well affect reproductionrelated hormonal systems as also on known consequences for fish living i
