Importância do estudo da reprodução em pequenos animais e preservação das espécies
Marcelo, Martinez-Barbitta
Although reproduction in small animals is relatively current, its objectives are very varied. Initially they were used as a study model in physiology and various pathologies. In the same way, many small animals are produced as food and finally, in the last 20 years, the importance of pets and the intensification in the selection of canine and feline breeds, has caused an important impulse in the development of new scientific information. Although currently technical resources have advanced substantially, there are still many basic and important issues that have not yet been elucidated by formal science. Global threats facing wild species include the consequences of climate change, population growth, urbanization, air and water pollution, and the release of chemicals into the environment, causing, on average, 25% of animals are in danger of extinction. Wild animal populations are small and dispersed in their habitat with little or no opportunity for genetic exchange, which has generated in recent years many programs to preserve wild species and design appropriate strategies that lead to sustainable populations. Fortunately, recent and inspiring advances in the science of wildlife reproduction have been reported that will set directions for future research and will surely lead to further successes in conservation biology.(AU)
