Language Dispersal Diversification And Contact

by Emily Irene Crevels, Language Dispersal Diversification And Contact Books available in PDF, EPUB, Mobi Format. Download Language Dispersal Diversification And Contact books, This book addresses the complex question of how and why languages have spread across the globe: why do we find large language families distributed over a wide area in some regions, while elsewhere we find clusters of very small families or language isolates? What roles have agriculture, geography, climate, ethnic identity, and language ideologies played in language spread? In this volume, international experts in the field provide new answers to these and related questions, drawing on the increasingly large databases available and on novel analytical research techniques.0The first part of the volume outlines some general issues and approaches in the study of language dispersal, diversification, and contact. In the rest of the volume, chapters compare the language and population histories of three major regions - Island Southeast Asia/Oceania, Africa, and South America - which show particularly interesting contrasts in the distribution of languages and language families. The volume is interdisciplinary in approach, with insights from archaeology, genetics, anthropology, and geography, and will be of interest to a wide range of scholars interested in language diversity and contact.

Origin Of Tropical Diversity From Clades To Communities

by James Edward Richardson, Origin Of Tropical Diversity From Clades To Communities Books available in PDF, EPUB, Mobi Format. Download Origin Of Tropical Diversity From Clades To Communities books, In this volume we aimed to assess progress in determining the processes by which current patterns of tropical biodiversity were established and are maintained. Tropical regions are highly species-rich and we present studies that have improved our understanding of the generation of that diversity at local, regional and global scales. We demonstrate how diverse fields from molecular phylogenetics, phylogeography, palaeontology and palaeoecology continue to improve our understanding of the natural history of the tropics.

Adaptive Speciation

by Ulf Dieckmann, Adaptive Speciation Books available in PDF, EPUB, Mobi Format. Download Adaptive Speciation books, Unraveling the origin of biodiversity is fundamental for understanding our biosphere. This book clarifies how adaptive processes, rather than geographic isolation, can cause speciation. Adaptive speciation occurs when biological interactions induce disruptive selection and the evolution of assortative mating, thus triggering the splitting of lineages. Internationally recognized leaders in the field explain exciting developments in modeling speciation, together with celebrated examples of rapid speciation by natural selection. Written for students and researchers in biology, physics, and mathematics, this book is a ground-breaking treatment of modern speciation science.

Paleolimnology

by Andrew S. Cohen, Paleolimnology Books available in PDF, EPUB, Mobi Format. Download Paleolimnology books, This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.

The Extended Specimen

by Michael S. Webster, The Extended Specimen Books available in PDF, EPUB, Mobi Format. Download The Extended Specimen books, The Extended Specimen highlights the research potential for ornithological specimens, and is meant to encourage ornithologists poised to initiate a renaissance in collections-based ornithological research. Contributors illustrate how collections and specimens are used in novel ways by adopting emerging new technologies and analytical techniques. Case studies use museum specimens and emerging and non-traditional types of specimens, which are developing new methods for making biological collections more accessible and "usable" for ornithological researchers. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series documents the power of ornithological collections to address key research questions of global importance.

Adaptive Diversification Mpb 48

by Michael Doebeli, Adaptive Diversification Mpb 48 Books available in PDF, EPUB, Mobi Format. Download Adaptive Diversification Mpb 48 books, Understanding the mechanisms driving biological diversity remains a central problem in ecology and evolutionary biology. Traditional explanations assume that differences in selection pressures lead to different adaptations in geographically separated locations. This book takes a different approach and explores adaptive diversification--diversification rooted in ecological interactions and frequency-dependent selection. In any ecosystem, birth and death rates of individuals are affected by interactions with other individuals. What is an advantageous phenotype therefore depends on the phenotype of other individuals, and it may often be best to be ecologically different from the majority phenotype. Such rare-type advantage is a hallmark of frequency-dependent selection and opens the scope for processes of diversification that require ecological contact rather than geographical isolation. Michael Doebeli investigates adaptive diversification using the mathematical framework of adaptive dynamics. Evolutionary branching is a paradigmatic feature of adaptive dynamics that serves as a basic metaphor for adaptive diversification, and Doebeli explores the scope of evolutionary branching in many different ecological scenarios, including models of coevolution, cooperation, and cultural evolution. He also uses alternative modeling approaches. Stochastic, individual-based models are particularly useful for studying adaptive speciation in sexual populations, and partial differential equation models confirm the pervasiveness of adaptive diversification. Showing that frequency-dependent interactions are an important driver of biological diversity, Adaptive Diversification provides a comprehensive theoretical treatment of adaptive diversification.
