Wildlife Mexico

Introduction

Mexico is one of the 12 megadiverse countries of the world. With over 200,000 different species, Mexico is home of 10-12 percent of the world's biodiversity. Mexico ranks first in biodiversity in reptiles with 733 known species, second in mammals with 448 species, fourth in amphibians with 290 species, and fourth in flora, with 26,000 different species. Mexico is also considered the second country in the world in ecosystems and fourth in overall species. Approximately 2,500 species are protected by Mexican law. The Mexican government created the National System of Information about Biodiversity, which is responsible for studying and promoting substantial use of ecosystems.

In Mexico, 170,000 square kilometers are considered "Protected Natural Areas." Including 34 reserve biospheres (unaltered ecosystems), 64 national parks, 4 natural monuments, 26 areas to protect the flora and fauna, 4 areas for natural protection and 17 sanctuaries (zones rich diversity of species).

Given the vastness of Mexico, stretching from the Atlantic Ocean to the Pacific Ocean, the country has a varied topography and important differences in climate, which favors a multivariate wildlife. It is a show that is the observation of large cetaceans. During the summer you can see the gray whales along the coast west to emigrate from Mexico to Alaska.


Endangered Species Mexico

In any ecosystem the animals both vertebrates and invertebrates, are a major factor. His relations with the other members of the ecosystem, helping to maintain a relative balance, whose stability, made possible by complex feedback mechanisms chain, easily agitated when affects any of its links, however insignificant they may seem.

Since its inception, the animals have been in competition for survival. In addition, constant changes in the environment have resulted in the disappearance of some species and the flourishing of others. These evolutionary processes occur slowly over millions of years, however, when the man came on the scene, relatively recently, the delicate faunal links who had long tenure in nature, began to break and be altered.
The extinction of some animal or other critical condition for human action has been recorded by some authors as Heim (1952) mentions, among other species definitely missing, the moa (Dinornis ingens) New Zealand giant ostrich.

The extinction of wildlife has serious impacts on ecosystems, particularly in relation to food chains and food. In most cases, the species disappeared not have enough information about their role in the different ecosystems in which they participated.

Chemical pollution is also a cause of injury to wildlife. Insecticides applied to crops, eventually entering streams rivers and seas, where they are ingested by organisms that are eaten by fish and other animals, and these, in turn, eaten by birds. At each step of the food chain, the insecticide is increasingly concentrated. Such concentrations in affected birds do that produce shell eggs deficient in calcium, which mothers pass break during incubation. As a result of this process the brown pelicans, cormorants and other birds are already extinct in some places where it prevailed. The insecticide pollution has even Antarctica and the Arctic affecting penguins and polar bears.

All these situations have been accentuated in this century due to human population explosion. Every day is necessary to clear forests and jungles to meet needs for food and room. For these reasons it is important to develop a national plan for the rational exploitation of wildlife resources. This project should take into account a range of social considerations, such as agriculture and altering natural areas affects wildlife. But how to convince these people to end the disturbance, when all efforts are barely enough to keep from starving?. How not to kill an ocelot recommend when selling your skin provides some income to relieve their already deteriorating economy?. Therefore, the scientists involved in wildlife conservation not only be able to propose protective measures but also in collaboration with other specialists, to present alternatives to meet the needs of society as a whole and not just the individual.


This comes to show first, that in Mexico there are no sufficient number of specialists in different ecological disciplines, and, secondly, they are often carried out investigations following foreign models and not according to our needs. Therefore it should train professionals aware of their social and scientific.
