What are Online First?

Online First are accepted manuscripts currently undergoing the final editing process before publication. To accelerate the dissemination of scientific knowledge, these manuscripts are made publicly available on the SciELO Preprints platform ahead of their official publication in Acta Botanica Brasilica. This early release increases the visibility of your research and allows feedback from the scientific community. Each preprint is assigned a DOI and remains citable as a permanent research record, which is subsequently linked to the final published version.
