This book was released on 2011-06-27 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of the European Commission’s concern for the status of continental waters, and as a clear reflection of the notion of water as heritage to be conserved, in the year 2000 the Water Framework Directive (2000/60/CE) was enacted, its goal being to establish a framework to protect water and the different aquatic ecosystems by requiring the Member States to achieve a good ecological status in all their waters by 2015. Like all ecosystems, freshwater ecosystems undergo physical, chemical and energy-related changes, both of natural and anthropogenic origin. These disturbances affect the organisms living in them and those who utilize their resources. Therefore, evaluating these changes has become a very important task in order to better understand aquatic systems. The study and analysis of the ecological status of these ecosystems in relation to their conservation status and water quality is thus a fundamental tool for a more efficient and rational management of their resources, that is, a management that does not threaten the ecosystem. The present guide for the identification of Spanish freshwater macroinvertebrates aims to facilitate the job of those who go to great lengths to identify them in order to then determine biotic indices. It is not the aim of this book to serve as a zoological treaty, nor does it claim to add new information on the biology or the ecology of the taxa covered. This book is, simply, a working tool explicitly designed to facilitate the identification of the Spanish macroinvertebrates and the subsequent computing of biotic indices.

Book excerpt: The Viva Natura: Field Guide to the Amphibians, Reptiles, Birds and Mammals of Western Mexico is the first publication of its kind written about the fauna of this region. The purpose of the field guide is to introduce the reader to the wealth of amphibians, reptiles, birds and mammals of Western Mexico and help identify them in the field. This guide contains the vast majority of the conspicuous animals of the region. In this second edition there are 230 species in this guide and a total of 440 full-color photos. The guide is extremely easy to use. The book is completely bilingual (English and Spanish). The book commences with a brief introduction to the study area, its geography, climate and ecosystems.

Each chapter begins with an introduction followed by photographic plates that depict conspicuous species of the study area. All photos were taken by the author himself and with few exceptions, show animals in their natural habitat under completely natural conditions. Each species is described by both its common and scientific names and also by a set of icons that illustrate the species characteristics, such as its habits, diet, preferred habitat, protection status, ect. Color bands on the outer edge of each species plate indicate one of the three principal habitat types (Ocean, Coast and Islands, Freshwater, Forest and Gardens) where this particular species can be observed most frequently. Silhouette thumbs on the plates edges portray a typical member of each group of fauna, making browsing the guide more efficient. The final chapter of the book is dedicated to the conservation issues inside the study area. The book is supported by a companion website where additional texts, photos and also videos and sounds can be found.
