          Diversity of ferns and lycophytes in Brazil

          Jefferson Prado, Lana Sylvestre, Paulo Labiak … (2015)
          Abstract This compilation of ferns and lycophytes in Brazil is an update of the one published in 2010 in Catálogo de Plantas e Fungos do Brasil. The methodology consisted in collecting data from regional checklists, taxonomic revisions, and selected databases. Invited specialists improved the list accessing a website housed at the Jardim Botânico do Rio de Janeiro. The results show 1,253 species: 1,111 of ferns and 142 of lycophytes. This number is 6.5% higher than the previous one (1,176 spp.). The percentage of endemic species decreased from 38.2% to 36.7%. We recognized 36 families and 133 genera (vs. 33 families, 121 genera in 2010). The 10 most diverse families are Pteridaceae (196 spp.), Dryopteridaceae (179), Polypodiaceae (164), Hymenophyllaceae (90), Thelypteridaceae (86), Aspleniaceae (78), Lycopodiaceae (64), Selaginellaceae (55), Anemiaceae (51), and Cyatheaceae (45). The three most diverse genera are still Elaphoglossum (87 spp.), Thelypteris (85), and Asplenium (74). The richest phytogeographic domain continues to be in the Atlantic Rainforest with 883 species which also has the largest number of endemic and threatened species, followed by the Amazon Rainforest (503), Cerrado (269), Pantanal (30), Caatinga (26), and Pampa (eight). Minas Gerais remains as the richest state (657 spp. vs. 580 in 2010).

            Licófitas e monilófitas das Unidades de Conservação da Usina Hidroelétrica - UHE de Tucuruí, Pará, Brasil

            Rozijane Santos Fernandes, Sebastião Maciel, Marcio Pietrobom (2012)
            O presente estudo refere-se às espécies de licófitas e monilófitas ocorrentes nas Zonas de Preservação da Vida Silvestre da Usina Hidroelétrica de Tucuruí, Estado do Pará, Brasil. A área de estudo localiza-se na região sudeste do Pará, com cerca de 29.700 hectares, composta, predominantemente, por floresta ombrófila aberta. Os dados obtidos demonstraram a ocorrência de 18 famílias, 37 gêneros e 82 espécies. A família com maior riqueza de espécies é Pteridaceae (21 spp.) e o gênero mais representativo é Adiantum com 14 espécies. Três espécies são novas referências para o Pará: Didymoglossum ovale, Danaea nodosa e Pecluma hygrometrica. Além disso, duas espécies novas foram identificados, uma delas já descrita, Thyelypteris amazonica. A outra espécie pertence a Adiantum e será publicada em breve. A riqueza florística da área, associada com as novidades taxonômicas, atesta a sua importância biológica e aponta para a necessidade de aumentar os esforços em pesquisa e conservação da área estudada.
