RESUMO
Comments are made about Brazil's rich biological patrimony, the value of which is still impossible to be appraised in a judicious manner. We are dealing with a highly valuable unknown and, for this very reason, still not utilised in a rational manner. The most extremely serious aspect, however, is the destruction that has for centuries affected the natural ecosystems and their respective wild biotas, even before their being scientifically better know. The importance of utilising this natural patrimony is emphasised, as well as the native domestic races of plants and animals that have been molded for centuries by Brazilian environmental conditions, and that nowadays represent valuable genetic material for agronomic and zootechnical research. The conference ends with remarks about the imbalance and environmental disasters, as well as the destruction of biodiversity, that have occurred in the Northeast of Brazil due mainly to the massive and irresponsible forestal devastation in the region.

Brazilian and Guianan callitrichids are categorized as endangered, vulnerable, common or status unknown. Endangered species should not be used in biomedical research and a continuing supply of wild-caught vulnerable species is also out of the question. Common species, on the other hand, could withstand limited sustained yield cropping without difficulty. Species categorized as status unknown should not be used until more data on them become available. Callitrichids have a higher reproductive potential than other New World monkeys, are for the most part quite adaptable, and are rarely hunted for food or captured as pets locally. Widespread habitat destruction is the major threat to their survival and species with naturally small ranges in areas of high human activity (e.g. Leontopithecus, Callithrix flaviceps) are in the greatest danger.
