"Adaptive biological diversification occurs when frequency-dependent selection generates advantages for rare phenotypes and induces a split of an ancestral lineage into multiple descendant lineages. Using adaptive dynamics theory, individual-based simulations, and partial differential equation models, this book illustrates that adaptive diversification due to frequency-dependent ecological interaction is a theoretically ubiquitous phenomenon"--Provided by publisher.

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.

This book presents 20 selected contributions to the 18th Evolutionary Biology Meeting, which took place in September 2014 in Marseille. They are grouped under the following major themes: · Genotype to Phenotype · Genetic Mechanisms of Diversification · Evolutionary Mechanisms · Speciation and Biodiversity The aims of these annual meetings in Marseille are to bring together leading evolutionary biologists and other scientists who employ evolutionary biology concepts, e.g. for medical research, and to promote the exchange of ideas and encourage interdisciplinary collaborations. Offering an up-to-date overview of recent advances in the field of evolutionary biology, this book represents an invaluable source of information for scientists, teachers and advanced students.

This book is about abiotic selection in Earth surface systems. It demonstrates that seemingly purposeful or goal-oriented phenomena in Earth's processes actually emerge from selection dynamics. While many think of selection in the context of biological evolution, it extends to abiotic processes crucial in understanding Earth's function and evolution. The author delineates four forms of geophysical selection: gradient, resistance, network, and thermodynamic. These selections manifest in various natural systems, from fluid flows shaping landscapes to the efficient transport of mass and energy. The book acknowledges the interplay of geophysical and ecological processes, employing them as pedagogical tools. Structured with an introduction to abiotic selection and its context, the book delves into the application of key principles—such as thermodynamics and flow dynamics—to Earth surface systems. Each subsequent chapter examines one of the four types of selection, featuring diverse real-world examples from climate dynamics to oceanography. Geared toward researchers, graduate students, and practitioners in fields such as geophysics, geology, geography, hydrology, and ecosystem sciences, it also appeals to those interested in evolutionary thinking beyond traditional life sciences.

Guanxi or interpersonal relationships is one of the major dynamics of Chinese society. A pervasive part of the Chinese business world for the last few centuries, it binds literally millions of Chinese firms into a social and business web. Any business in this society, including local firms and foreign investors and marketers, inevitably faces guanxi dynamics. In China's new, fast-paced business environment, guanxi has been more entrenched than ever, heavily influencing Chinese social behavior and business practice. However, as in other emerging economies, corruption in China is becoming more rampant, which makes guanxi and corruption often intermingled. As such, business executives need to place greater caution today in the practice and process of guanxi development and utilization.Due to the growing academic and practical interest in guanxi, this second edition provides a timely update to the systematic and vigorous exploration of the various social, economic, cultural, and business issues relating to the complex concept and practice of guanxi.
