Resumo

Hawkmoths are an important component of tropical ecosystems, with significant roles as herbivores and pollinators. These moths can be used as indicators in biodiversity assessments because they can be easily sampled and identified. However, hawkmoths have seldom been surveyed over the long term for this purpose, especially in the Neotropical region. Considering that long-term datasets are of indisputable importance for understanding and monitoring temporal changes in biodiversity, this study assessed long-term changes in the hawkmoth fauna in a protected Atlantic Rain Forest area over a period of 64 years. We used historical and recent empirical datasets to ask whether faunal-diversity patterns and species composition have changed over time. We used individual- and sample-based rarefaction and extrapolation curves based on Hill number (diversity order of q = 0) to compare species richness, and the probability version of the abundance-based Chao-Jaccard index to assess beta diversity over time. To assess changes in faunal composition, we conducted a nonmetric multidimensional scaling analysis and performed an analysis of similarities to test whether the community composition has changed. Our results clearly showed long-term stability of the hawkmoth community over the 64 years, despite the growing human-induced landscape changes that occurred in the region surrounding the study area during the last 6 decades. This study emphasizes the importance of large remnants of Atlantic Forest for long-term maintenance of both functional diversity and ecosystem functioning. (AU)
