          Abstract

          O presente estudo comparou a comunidade e a diversidade de aves em fragmentos de Floresta Ombrófila Mista de diferentes tamanhos. Para tanto, oito fragmentos divididos em conjuntos, formando duas classes (somando de 20 a 70 ha e de 100 a 420 ha), foram selecionados em quatro fazendas no distrito de Guamirim, Irati-PR. O método de amostragem consistiu em trajetos irregulares percorridos pelas áreas naturais, realizados entre 2009 e 2010, sempre na primavera e no outono. Foram calculadas a Frequência Relativa e a Diversidade mediante o índice de Shannon. As análises MRPP e Cluster, e o teste Mann-Whitney (Wilcoxon) W foram utilizados para comparar os fragmentos. Os resultados comprovam que fragmentos maiores abrigam uma comunidade distinta e mais diversa do que manchas menores do que 100 ha. Foram registradas 88 espécies pelos trajetos irregulares. Somando estas às espécies anotadas a partir de observações eventuais em qualquer área dentro das fazendas e nos seus arredores, obteve-se um total de 123 espécies registradas localmente.

          This study compared the community and diversity of birds in Mixed Ombrophylous Forest fragments of different sizes. To this end, eight fragments divided into sets forming two classes (from 20 to 70 ha and 100 to 420 ha) were selected in four farms in Guamirim district, municipality of Irati, Paraná state. The sampling method consisted of irregular transects traversed by natural areas. The experiment was conducted between 2009 and 2010, always in spring and autumn. Relative Frequency and Diversity were calculated by the Shannon index. The analyses Multiple Response Permutation Procedure (MRPP), Cluster, and Mann-Whitney (Wilcoxon) W test were used to compare the fragments. The results show that larger fragments present a distinct and more diverse community than patches smaller than 100 ha. Using irregular transects, we recorded 88 species of the total of 123 species recorded on site in transects and eventual observations.

              Have we overstated the tropical biodiversity crisis?

              Tropical forests are the most biologically diverse and ecologically complex of terrestrial ecosystems, and are disappearing at alarming rates. It has long been suggested that rapid forest loss and degradation in the tropics, if unabated, could ultimately precipitate a wave of species extinctions, perhaps comparable to mass extinction events in the geological history of the Earth. However, a vigorous debate has erupted following a study by Wright and Muller-Landau that challenges the notion of large-scale tropical extinctions, at least over the next century. Here, I summarize this controversy and describe how the debate is stimulating a serious examination of the causes and biological consequences of future tropical deforestation.
