Einar Topiltzin Contreras MacBeath A thesis submitted in partial fulfilment of the requirements of the Manchester Metropolitan University for the degree of Doctor of Philosophy School of Science and the Environment, Faculty of Science and Engineering of the Manchester Metropolitan University 2014 ABSTRACT Due to human activities freshwaters are experiencing declines in biodiversity far greater than those in the most affected terrestrial and marine ecosystems, consequently freshwater fishes are by far the most affected group of vertebrates. This situation stands true for Mexican freshwater fishes and their corresponding ecosystems. In this respect, Mexico has a long history of environmental policy, and seeking to protect its biodiversity, the country has carried out a series of important initiatives in response to the adoption of the Convention on Biological Diversity (CBD), such as the creation of the National Biodiversity Commission in 1992, the elaboration of the National Biodiversity Strategy, regional action plans, as well as conservation strategies for terrestrial and marine species and environments, but unfortunately, little has been done in relation to the conservation of freshwater species, nor the ecosystems they live in. With this in mind, the main aim of this study is to analyze the spatial distribution of the Freshwater Fishes of Mexico, their conservation status, and to develop a conservation strategy for species with imminent risk of extinction.
