RESUMO:

Understanding the patterns of ecosystem cycles is fundamental for ecology, since a good part of the natural environments are being fragmented by strong impacts on inappropriate land use, as occurs in the extensive ecotonal region between the Amazon and Cerrado biomes. Chiropterans have high diversity in these biomes and have an important ecological role, such as phytophagous bats that feed on plant parts, ensuring the pollination and dispersion of a range of plant species. Our research aimed to understand this bat-plant interaction on a geographic scale between Amazon-Ecotone-Cerrado, in order to assess the plant diversity associated with bats, as well as responses to fragmentation based on plant resources, ecological relationships and the importance of fruit bats in the germination of these plant species. We captured frugivorous bats in 24 connected and isolated forest remnants distributed in the Amazon (n=8), Ecotone (n=8) and Cerrado (n=8) biome. The bats were captured with mist nets and the feces collected were screened in the laboratory and submitted to germination experiments. We also analyzed the bat-plant interactions and tested the effects of different treatments of post-digestive tract seeds to verify which treatment best meets the germination process, where finally we provide a protocol for carrying out these experiments. We identified 77 seed morphotypes with similar Cerrado and Ecotone. The networks identified 348 interactions distributed in 178 links. The germination results showed that the treatment of unwashed seeds is the most viable in experiments with seeds after the digestive tract of bats, when compared to the other treatments. The results show the importance of broad studies to understand bat-plant interactions, add a protocol for germination experiments and reinforce the importance of frugivory by bats for native plant maintenance
