Item Acesso aberto (Open Access) Licófitas (Lycopodiophyta) do corredor de biodiversidade do norte do Pará, Brasil(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2015-03) GÓES NETO, Luiz Armando de Araújo; ROSÁRIO, Sebastião Maciel do; SILVA, Marcio Roberto Pietrobom da; VALDESPINO, Iván AlbertoA treatment of the lycophytes of the Northern Pará Biodiversity Corridor within the Guiana Endemism Center is presented. This article is part of the project “Diagnóstico da Biodiversidade das Unidades de Conservação estaduais do Mosaico Calha Norte, Estado do Pará”. The treatment includes keys as well as species descriptions. In the study area 14 species distributed in four genera (Palhinhaea, Phlegmariurus, Pseudolycopodiella and Selaginella) were registered. The most diverse genus was Selaginella with 10 species, of which S. fragilis A. Braun and S. revoluta Baker are new records for Pará, and S. gynostachya Valdespino and S. sandwithii Alston are reported here as new to the Brazilian flora.Item Acesso aberto (Open Access) Licófitas e samambaias da Serra do Itauajuri, município de Monte Alegre, Pará, Brasil(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2016-12) GÓES, Julieta Pallos Pinto de Araújo; GÓES NETO, Luiz Armando de Araújo; COSTA, Jeferson Miranda; SOUZA, Filipe Soares de; SILVA, Marcio Roberto Pietrobom daIn this study we present the lycophytes and ferns inventoried in the Serra do Itauajuri, Pará state. Sixty four species distributed in 36 genera and 21 families were registered, with one family, one genus, and four species belonging to the lycophytes lineage, and 20 families, 35 genera, and 60 species belonging to the ferns lineage. The most representative families were Pteridaceae (19 spp.), Polypodiaceae (8), and Selaginellaceae (4). The genera with highest species richness were Adiantum (9 spp.) and Selaginella (4). Most species were collected as terrestrial (35 spp., ca. 55%), occurring in riparian forests (51 spp., ca. 80%), with American distribution pattern (46 spp., ca. 72%). We present two new records for the Northern Region of Brazil (Asplenium pumilum and Marsilea ancylopoda) and two for Pará state (Ophioglossum nudicaule and Selaginella minima). The studied area has distinct environmental characteristics than those commonly observed in Brazilian Amazonia, being a biologically important area. This results gathered information that can support the creation and implementation of the Serra do Itauajuri Conservation Unit, which will guarantee the preservation of its historic and natural wealth.
