30 Second Ecology

Whether you're looking to save the planet or learn more about your local environment, 30-Second Ecology introduces you to the diversity, behaviours and challenges within our ecosystem. Part of the 30-Second series, this introductory guide to ecology is split into 7 chapters that cover: Evolution & Ecology Behavioural Ecology Population Ecology Communities & Landscapes Biomes & Biodiversity Applied Ecology Ecology in a Changing World Plus profiles of notable ecologists, such as Robert H. Macarthur, Rachel Carson and Wangari Maathai. Each topic is summarised in 300 words with one image, helping you understand the subject at great speed. Written by professors and experts from around the world, this book shows us that humans are truly part of this global ecology, not a separate entity from it and our collective actions have far-reaching ramifications on the environment around us.

Endowed with abundant water, extraordinary ecoystems, varied climates and biomes, our planet is teeming with creatures, great and small. What produced this rich diversity? How have so many species formed, evolved and adapted? What effects are humans having on the rest of the animal kingdom and on the natural environment we share? 30-Second Zoology explains the diversification process of evolution, then introduces the main groups of invertebrates and vertebrates. Breathing, seeing, communicating and other key features of animal physiology and behaviour are explored, as are the ecological relationships between Earth’s myriad species – the predators, the prey, the parasites and the positively poisonous – before assessing the anthropogenic effects of pollution, over-harvesting and a changing climate. Covering everything from the origins of life and the most basic of organisms, all the way through to the more complex creatures that we recognise today, 30-Second Zoology aims to showcase the most fantastic examples of life on our earth, all in 300 words and one stunning illustration per topic.

Offering a balance of subject matter emphasis, clearly presented concepts and engaging examples, this book aims to help students gain a better understanding of ecology. Emphasis is placed on connections in nature, the importance of ecology to environmental health and services, and links to evolution.

This is an up-to-date study of patterns and processes involving two or more species. The book strikes a balance between plant and animal species and among studies of marine, freshwater and terrestrial communities.

Dozens of real-life applications and examples of this framework currently in use are examined, including three in-depth cases studies: work with marine fisheries in Hawai'i, strategies of eco-activists to protect Canada's Great Bear Rainforest, and a study of community development in El Salvador. In addition, eighteen personal practices of transformation are provided for you to increase your own integral ecological awareness."--Jacket.

A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities? What other scientific areas might serve as a guiding framework? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology's various perspectives into a more unified whole. Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities. Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.
