The culmination of six years of research, this book compiles articles published by scholar and conservationist Alejandro Martinez Abrain in Quercus magazine from 2008 to 2013. The essays include analyses of ecological and evolutionary processes that functionally support nature, including human activity, and clues to the workings of our biosphere, which is a common theme addressed in the UK, Australia, and the United States but not in other parts of the world. Although this book is written with exactitude, it is accessible to any reader and includes examples that anyone can understand. The reading won't leave you unaffected about nature--or our own human nature.
