Although biologists recognize evolutionary ecology by name, many only have a limited understanding of its conceptual roots and historical development. Conceptual Breakthroughs in Evolutionary Ecology fills that knowledge gap in a thought-provoking and readable format. Written by a world-renowned evolutionary ecologist, this book embodies a unique blend of expertise in combining theory and experiment, population genetics and ecology. Following an easily-accessible structure, this book encapsulates and chronologizes the history behind evolutionary ecology. It also focuses on the integration of age-structure and density-dependent selection into an understanding of life-history evolution. - Covers over 60 seminal breakthroughs and paradigm shifts in the field of evolutionary biology and ecology - Modular format permits ready access to each described subject - Historical overview of a field whose concepts are central to all of biology and relevant to a broad audience of biologists, science historians, and philosophers of science

Amphibians are the oldest tetrapod group and show an astonishing diversity in lifestyles, many of them being unique. However, globally, they are on a decline. Hence, their study is fundamental to understanding the evolution of diversity and conserving them. This book, authored by experts from around the world, summarizes the current knowledge on the evolutionary ecology of amphibians. The book treats biological concepts related to the evolution, ecology, physiology, immunology, behaviour, and morphology of amphibians in their different states. This book constitutes an actualized work indispensable for evolutionary ecologists and herpetologists.

In Waterton Lakes National Park, located in southwest Alberta, Canada, under-road crossing structures were installed in 2008 to protect a population of long-toed salamander (Ambystoma macrodactylum) at Linnet Lake from mortality during breeding migrations that intersected with the park's entrance road. This compilation first investigates orientation and movement patterns of marked individuals at Linnet Lake in 2013 and 2014, and at a smaller, shallower wetland Stable Pond in 2014 to document in detail how long-toed salamanders used the terrestrial landscape around breeding sites during adult migration and juvenile dispersal. Following this, the authors use generalized linear models to model salamander occurrence and abundance in the Beaver Hills region of north-central Alberta as a function of land cover type and pocket gopher density. The authors go on to address whether any ecological barriers exist in the distribution range of the two newt species N. strauchii and N. crocatus. According to the findings of this study, an identity test was found to be significantly different from the null distribution, whereas a background test was not significantly different from the null distribution. The concluding chapter summarizes the processes by which light is converted into neural signals by rods and cones and then transmitted to downstream neurons in the retina, with a focus on salamander photoreceptors. The different types of photoreceptor cells and other light-sensitive cells in salamanders and their role in vision are also discussed.

Evolutionary Ecology simultaneously unifies conceptual and empirical advances in evolutionary ecology and provides a volume that can be used as either a primary textbook or a supplemental reading in an advanced undergraduate or graduate course. The focus of the book is on current concepts in evolutionary ecology, and the empirical study of these concepts. The editors have assembled a group of prominent biologists who have made significant contributions to this field. They both synthesize the current state of knowledge and identity areas for future investigation. Evolutionary Ecology will be of general interest to researchers and students in both ecology and evolutionary biology. Researchers in evolutionary ecology that want an overview of the current state of the field, and graduate students that want an introduction the field, will find this book very valuable. This volume can also be used as a primary textbook or supplemental reading in both upper division and graduate courses/seminars in Evolutionary Ecology.

The Trinidadian guppy represents a uniguely tractable vertebrate system, which has raised key questions in evolutionary ecology and supplied many of the answers. This work discusses this study and incorporates significant new findings and insights.

Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

This volume consists of four chapters that cover a structurally diverse range of naturally occurring compounds. Chapter 1 delves into the chemistry of pyrogallols and their oxidized products, the hydroxy-o-quinones, including their role in cycloaddition reactions in the chemical synthesis of several fungal metabolites. Chapter 2 provides an in-depth description of the constituents of agarwood essential oil and smoke samples that are used in the perfumery industry, with an emphasis on the sesquiterpenoid and chromones constituents so far known. Chapter 3 discusses the defensive chemical ecology of two North American newt species that both produce tetrodotoxin, a well-known neurotoxin that causes paralysis and death in metazoans by disrupting electrical signals in the nerves and muscles. Chapter 4 discusses the limonoids and triterpenoids from the genus Walsura of the plant family Meliaceae, of which a number of species are utilized in several southeastern Asian countries in systems of folk medicine.

The 'Adaptive Landscape' has been a central concept in population genetics and evolutionary biology since this powerful metaphor was first formulated in 1932. This volume brings together historians of science, philosophers, ecologists, and evolutionary biologists, to discuss the state of the art from several different perspectives.

Nearly thirty years after the publication of the last detailed book on the newts and salamanders of Europe, this book at last provides a much needed, modern coverage of the ecology, behaviour, evolution and conservation of these fascinating amphibians. It shows how the diversity of newt and salamander life-styles underlines how this relatively small group of animals has managed to survive in such diverse habitats as underground caves, mountain tops, tropical forests and the Siberian tundra. The species accounts are accompanied by notes and maps on distribution, habitat requirements and behaviour, as well as colour photographs of every species. Features: * Presents the first synthesis of research for nearly 30 years * Reviews current conservation issues * Provides up-to-date species accounts and color photos * Includes a user-friendly guide to the relationships between different species and subspecies
