“…Species were also found in gaps, ravines and marshes, as well as along the edges of trails, on the banks of brooks and among rocky outcrops. The predominant ecological aspects at the study site were those commonly observed for the fern group and similar to those reported in other studies conducted in areas of northeastern Atlantic Forest (Xavier & Barros 2005;Santiago & Barros 2003;Santiago et al 2004;Barros et al 2006;Pietrobom & Barros 2007;Pereira et al 2007).…”

“…The families Pteridaceae and Polypodiaceae are frequently highlighted in floristic surveys in the northeastern Atlantic Forest, such as those conducted by Santiago & Barros (2003), Santiago et al (2004), Xavier & Barros (2005), Pietrobom & Barros (2007), Pereira et al (2007) and Pereira et al (2011). Smith et al (2006) commented that Pteridaceae consists of a typically tropical group, whereas Polypodiaceae is defined by Tryon & Tryon (1982) as comprising plants that commonly occur in the neotropics.…”

“…According to Tuomisto & Ruokolainen (1994), the terricolous substrate is more common in this group because soils offer varied physical and chemical conditions, such as solar irradiation, temperature and humidity, in addition to a higher nutrient availability. However, the considerable representativeness of the epiphytic species should be noted, because such species are typically demanding in terms of environmental quality and therefore usually have low representativeness in forest fragments of this region (Xavier & Barros 2003, 2005Santiago & Barros 2003;Barros et al 2006;Pietrobom & Barros 2007;Pereira et al 2007).…”

We conducted a floristic survey of ferns within the Murici Ecological Station (remnant of the northeastern Atlantic Forest), located near the municipalities of Messias and Murici, in the state of Alagoas, Brazil. To increase knowledge of the ferns of Alagoas, we evaluated the species occurring in the study area in terms of richness, composition, geographic distribution, similarities with species in other Brazilian biomes, regional conservation status and ecological aspects. Data were obtained from field work conducted between March 2009 and September 2010. We identified 107 species of ferns, of which 19 represent new records for Alagoas. The richest families were Pteridaceae (29 species) and Polypodiaceae (22 species). The richest genera were Adiantum (15 species) and Thelypteris (9 species). Most of the species sampled are widely distributed throughout Brazil and the Americas. Within the context of the northeastern Atlantic Forest, 12 species were considered endangered. Concerning the ecological aspects, 88.8% of the species identified were herbaceous, 57.9% were terrestrial and 70.0% occurred in the forest interior.

-(Lycophytes and monilophytes from Unidades de Conservação da Usina Hidroelétrica -UHE Tucuruí, Pará, Brazil). This work presents a survey of lycophytes and monilophytes in the Conservation Unit named Zonas de Preservação da Vida Silvestre da Usina Hidrelétrica de Tucuruí, Pará State, Brazil. This Conservation Unit is located at southeastern Pará and comprises about 29,700 ha, composed mainly of tropical rainforest. Our results recorded 18 families, 37 genera and 82 species. The richest family is Pteridaceae, with 21 species, and Adiantum is the richest genus, with 14 species. Three species are new records for Pará State: Didymoglossum ovale, Danaea nodosa, and Pecluma hygrometrica. Furthermore, two new species were identified. One has already been described, Thyelypteris amazonica. The other new species belongs to the genus Adiantum and shall be published soon. The floristic richness of the area, associated with the taxonomic novelties, attests for its biological importance and for the necessity of increasing the efforts on research and conservation of the study area. Key words: Amazon Forest, fern, floristic RESUMO -(Licófitas e monilófitas das Unidades de Conservação da Usina Hidroelétrica -UHE de Tucuruí, Pará, Brasil). 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.

“…Todavia, quando comparado a estudos em áreas menores e com sinais de antropização, mesmo em outros estados nordestinos, os resultados aqui apresentados mostram-se ainda mais semelhantes. Por exemplo, os trabalhos de Pereira et al (2007) e Pietrobom & Barros (2007), ambos realizados no estado de Pernambuco, registraram predominância das mesmas famí-lias, além de destacarem os gêneros Adiantum e Thelypteris como os mais representativos.…”

Resumo -É apresentado o levantamento das licófitas e samambaias do Parque Metropolitano de Pituaçu, Salvador, Bahia. Foram registradas 36 espécies, pertencentes a 22 gêneros e 14 famílias. As famílias mais representativas foram Pteridaceae, com 11 espécies distribuídas em cinco gêneros (Acrostichum, Adiantum, Pityrogramma, Pteris e Vittaria), e Thelypteridaceae, com seis espécies distribuídas em dois gêneros (Macrothelypteris e Thelypteris). Os gêneros com maior número de espécies foram Adiantum (6) e Thelypteris (5). A maioria das espécies apresentou-se como herbácea e terrícola. Este é o primeiro estudo abordando exclusivamente as licófitas e samambaias em um remanescente florestal urbano na cidade de Salvador. Palavras-chave adicionais: biodiversidade, florística, Mata Atlântica, pteridoflora.Abstract (Lycophytes and ferns from the Parque Metropolitano de Pituaçu, Municipality of Salvador, Bahia, Brazil) -This work presents the survey of lycophytes and ferns from the Parque Metropolitano de Pituaçu, Salvador, Bahia State. The 36 registered species belong to 22 genera and 14 families. The most representative families were Pteridaceae, with 11 species in five genera (Acrostichum, Adiantum, Pityrogramma, Pteris and Vittaria), and Thelypteridaceae, with six species in two genera (Macrothelypteris and Thelypteris). The genera with higher number of species were Adiantum (6) and Thelypteris (5). The majority of the species was herbaceous and terrestrial. This is the first study addressing exclusively lycophytes and ferns in a urban forest remnant in Salvador City.
