Fenologia e distribuição geográfica dos gêneros tabebuia e handroanthus no nordeste brasileiro - utilizando dados de herbários

Abstract

The preservation of plant biodiversity is extremely important, and tools such as SpeciesLink, which brings together data from 587 herbaria and 17.7 million records, are essential to assist in this process. This work aims to characterize the distribution of genera and analyze the phenology of species in Northeast Brazil using data from virtual herbaria. The study was based on data from exsiccates from virtual herbaria of the genus Tabebuia and Handroanthus. The data was analyzed regarding geographic distribution, period of abundance and collection frequency. 10 species of the genus Tabebuia and 20 species of Handroanthus were found. The species T. aurea was the most frequent for Tabebuia, while H. impetiginosus was for Handroanthus. The distributed distribution analysis showed that the species of Tabebuia and Handroanthus are present in all states in the Northeast. Phenology analysis showed that species of the Tabebuia genus flower from September to December, while species of the Handroanthus genus flower from July to October. With this, this research concludes that the data present on the platforms contains important information about the geographic distribution and information about the species recorded for the genera Tabebuia and Handroanthus in Northeast Brazil, which can help in the conservation and sustainable use of these species.
