Book excerpt: Modern information and communication technologies, together with a cultural upheaval within the research community, have profoundly changed research in nearly every aspect. Ranging from sharing and discussing ideas in social networks for scientists to new collaborative environments and novel publication formats, knowledge creation and dissemination as we know it is experiencing a vigorous shift towards increased transparency, collaboration and accessibility. Many assume that research workflows will change more in the next 20 years than they have in the last 200. This book provides researchers, decision makers, and other scientific stakeholders with a snapshot of the basics, the tools, and the underlying visions that drive the current scientific (r)evolution, often called ‘Open Science.’

Available in PDF, EPUB and Kindle. Book excerpt: This state-of-the art research Handbook provides a comprehensive, coherent, current synthesis of the empirical and theoretical research concerning teaching and learning in science and lays down a foundation upon which future research can be built. The contributors, all leading experts in their research areas, represent the international and gender diversity that exists in the science education research community. As a whole, the Handbook of Research on Science Education demonstrates that science education is alive and well and illustrates its vitality. It is an essential resource for the entire science education community, including veteran and emerging researchers, university faculty, graduate students, practitioners in the schools, and science education professionals outside of universities. The National Association for Research in Science Teaching (NARST) endorses the Handbook of Research on Science Education as an important and valuable synthesis of the current knowledge in the field of science education by leading individuals in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation. Worldwide climatic changes have been raising concerns about potential changes to crop yields and production systems. Such concerns include the ability to accommodate these uncertain effects in order to ensure an adequate food supply for an increasing population. Written by leadinginternational experts, this book is the first comprehensive examination of the potential effects climate change, particularly green house gases, will have on agroecosystems. It also reviews the effects such systems have on climate change itself.

Download or read book Mammalian Dispersal Patterns written by B. Diane Chepko-Sade and published by University of Chicago Press. This book was released on 1987 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mammalian Dispersal Patterns examines the ways that social structure affects population genetics and, in turn, rates of evolution, in mammalian groups. It brings together fieldwork in animal behavior and wildlife biology with theoretical work in demography and population genetics. The focus here is dispersal—whether, how, and when individuals leave the areas where they are born. Theoretical work in population genetics indicates that such social factors as skewed sex ratios, restrictive mating patterns, and delayed age of first reproduction will lower the reproductive variability of a population by reducing the number of genotypes passed from one generation to the next. Field studies have shown that many mammalian species do exhibit many such social characteristics. Among horses, elephant seals, and a number of primates, the majority of females are inseminated by only a fraction of the males. In pacts of wolves and mongooses, usually only the highest-ranking male and female breed in a given season. Although socially restricted mating tends to lower genetic variability in isolated populations, it actually tends to increase genetic variability in subdivided populations with low rates of migration between subunits. Among some species there is little dispersal and thus little gene flow between subpopulations; other species travel far afield before mating. The contributors to this volume examine actual data from populations of mammals, the way patterns of dispersal correlate with the genetic structure of individuals and populations, and mathematical models of population structure. This interdisciplinary approach has an important bearing on work in conservation of both wildlife and zoo populations, for it shows that the home range and the population size needed to maintain genetic variability can differ greatly from one species to the next. The volume also offers a fruitful model for future research.

Download or read book The Nine-Banded Armadillo written by Colleen M. McDonough and published by University of Oklahoma Press. This book was released on 2013-03-18 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The word armadillo is Spanish for “little armored one.” This midsize mammal that looks like a walking tank is a source of fascination for many people but a mystery to almost all. Dating back at least eleven million years, the nocturnal, burrowing insectivore was for centuries mistaken for a cross between a hedgehog and a turtle, but it actually belongs to the mammalian superorder Xenarthra that includes sloths and anteaters. Biologists W. J. Loughry and Colleen M. McDonough have studied the nine-banded armadillo (Dasypus novemcinctus) for more than twenty years. Their richly illustrated book offers the first comprehensive review of everything scientists know about this unique animal. Engaging both scientists and a broader public, Loughry and McDonough describe the armadillo’s anatomy and physiology and all aspects of its ecology, behavior, and evolution. They also compare the nine-banded armadillo with twenty or so other, related species. The authors pay special attention to three key features of armadillo biology—reproduction, disease, and habitat expansion—and why they matter. Armadillos reproduce in a unique and puzzling manner: females always give birth to litters of genetically identical quadruplets, a strategy not found in any other vertebrates. Nine-banded armadillos are also the only vertebrates except for humans known to contract leprosy naturally. And what about habitat expansion? The authors suggest that the armadillo’s remarkable spread across the southeastern United States may be the consequence of its most notable feature: a tough, protective carapace. Biologists, evolutionists, students, and all those interested in this curious creature will find The Nine-Banded Armadillo rich in information and insight. This comprehensive analysis will stand as the definitive scientific reference for years to come and a source of pleasure for the general public.
