ABSTRACT
In the last decades, herpetologists from all over the world have been turning their attention to a phenomenon that is documented on a world-wide scale: the decline of amphibians. Many factors have been attributed to this decline; among them, the use of pesticides. The purpose of this article is to make, a temporal quantitative analysis, using a scientific-metric approach of the terms fertilizer, herbicide, insecticide or pesticide, and amphibian , from 1980 until august of 2007. For this analysis, a review was done of titles and abstracts of available articles on the ISI Web of Science (Institute for Scientific Information) (1). Two hundred and twenty-nine articles were found. The first publication found is from 1980, but a significant increase in the number of published works was found starting in 1997. This could be explained by the fact that the information declines and extinctions on accelerates during the 1990's. The articles were published by authors from 27 countries, but 54% of them were written by authors who work in the United States of America , followed by those who work in Canada (17%). The predominance of the U.S.A can be explained by the fact that the majority of indexed journals belong to this country and that the first records of declines associated with pesticides are observed in its own territory. Only one article was published by main authors who were working in Brazil , demonstrating that in spite of the intense use of chemical pesticides, little is being invested in research on the effects of these substances on the native fauna amphibian. The publications were classified into thirty areas of knowledge, indicating the highly interdisciplinary nature of the subject. In Brazil , agriculture takes up about 7% of the national territory and there is little or no information about the effects of agricultural chemicals on the amphibian fauna, making the development of research that will evaluate the real effects of chemical pesticides on the Brazilian wild fauna, an urgent matter.
