“…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.

However, some taxa are not usually registered in NAF, such as Megalastrum umbrinum (Farias et al 2015), which has been found only in the present area, as well Elaphoglossum glabellum and Ctenitis glandulosa, which had few records in this unit and were previously recorded in two other NAF areas.…”

Inventory of Ferns and Lycophytes of the RPPN Pedra D'Antas, Pernambuco state, northeastern Brazil

et al. 2017

The Northeastern Atlantic Forest (NAF) has a historic of intense habitat loss and fragmentation. In this context, knowledge of the species from forest remnants is urgently needed and represents a key tool for future studies and conservation strategies. Here, we present the floristic inventory of ferns and lycophytes from the Private Natural Heritage Reserve - RPPN Pedra D'Antas, located in a NAF area. The study area associated with the RPPN Frei Caneca is the Serra do Urubu, which is a hotspot for the diversity of several biological groups in the NAF. We recorded 74 fern species, distributed in 17 families and 46 genera. The most diverse families were Pteridaceae (17 species), Polypodiaceae (14 spp.), Dryopteridaceae (nine spp.) and Thelypteridaceae (seven spp.). Lycophytes were represented by four species, two families and two genera. A new record for the Northeast of Brazil, Serpocaulon hirsutulum, is presented in this study. The area has a large number of species, some of which are restricted to the NAF (e.g. Megalastrum umbrinum). Based on the richness of the study area associated with another inventory held at the RPPN Frei Caneca (138 spp.), the Serra do Urubu is corroborated as a hot-spot for the diversity of ferns and lycophytes in the NAF.

“…De um modo geral as espécies foram mais coletadas no interior da mata, com (60%), superando as de borda (18%), porém algumas se mostraram indiferentes (22%) (Tabela 3). Estes padrões são observados em muitos trabalhos com samambaias e licófitas na região (PIETROBOM; SANTIAGO et al, 2004;PEREIRA et al, 2011).…”

A Mata do Buraquinho é um remanescente de Mata Atlântica na região Nordeste do Brasil, em área urbana. O estudo foi baseado em coletas realizadas pelos autores ao longo das três últimas décadas e no levantamento dos principais herbários no Nordeste brasileiro. Foram registradas 22 espécies, uma licófita e 21 samambaias (distribuídas em 16 gêneros e 10 famílias). A maioria das espécies é amplamente distribuída no território americano e nas regiões brasileiras, algumas com poucos registros na área ocupada pela Mata Atlântica nordestina: Psilotum nudum (L.) P. Beauv., Ceratopteris thalictroides (L.) Brongn. e Actinosthachys subtrijuga (Mart.) C. Presl. Em relação aos aspectos ecológicos, a maioria das espécies se apresentou como herbácea, terrícola e hemicriptófita, ocorrendo no interior dos fragmentos. Em relação ao uso potencial, mais de 70% das espécies apresentam alguma indicação medicinal, ornamental ou alimentícia. Apesar do número reduzido de espécies, a flora de samambaias e licófitas da Mata do Buraquinho apresenta riqueza expressiva no contexto estadual, com espécies que ressaltam a importância dessa flora e a necessidade de sua preservação.

Mata do Buraquinho is a remnant of Atlantic Forest in the Northeast region of Brazil, in an urban area. The study was based on collection made by the authors over the last three decades and on the survey of the major herbaria in northeastern Brazil. We registered 22 species, 1 lycophyte and 21 ferns (distributed into 16 genera and 10 families). Most species are widely distributed in the American territory and in the Brazilian regions, some of them with few records in the area occupied by the northeastern Atlantic Forest: Psilotum nudum (L.) P. Beauv., Ceratopteris thalictroides (L.) Brongn. and Actinosthachys subtrijuga (Mart.) C. Presl. Regarding the ecological aspects, most species showed up as herbaceous, terrestrial, and hemicryptophyte, occurring within the fragments.
