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

Abstract

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.

Lycophytes of the Chapada das Mesas National Park, Cerrado, Maranhão, Brazil

“…Most of the species cataloged in this study are widely distributed in nearly all phytogeographic domain, such as Palhinhaea cernua (Amazon, Brazilian Cerrado, Atlantic Forest, as well as mangrove ecosystems), Selaginella erythropus (Caatinga, Brazilian Cerrado, Atlantic Forest,), S. simplex (Amazon, Caatinga, Brazilian Cerrado) (Bastos & Cutrim 1999, Azevedo & Silva 2001, Pietrobom & Barros 2003, Fernandes et al 2007, Maciel et al 2007, Conceição & Rodrigues 2010, Fernandes et al 2010, Prado & Sylvestre 2010, Barros 2013, Santiago et al 2014, Farias et al 2017, Prado & Sylvestre 2010, Silvestre et al 2019). The exception is S. conduplicata that, until now, was cited to Amazonia and Atlantic Forest in Northeastern (Ceará e Pernambuco) (Silva 2014).…”

Ferns and Lycophytes of Pernambuco state, Brazil: Serpocaulon (Polypodiaceae)

“…Although fern diversity has been extensively studied in Pernambuco , 2010Barros et al 2006;Farias et al 2017;Pereira et al 2007Pereira et al , 2011Pietrobom & Barros 2007;Santiago et al 2004Santiago et al , 2014Xavier & Barros 2003), the information and records of Serpocaulon species are still scarce.…”

Samambaias de um fragmento de Floresta Ombrófila Densa em zona urbana, Maciço de Baturité, Ceará, Brasil

“…do país. No Nordeste, os estudos vêm crescendo, como os realizados porSantiago et al (2004), Conceição e Rodrigues (2010),Pereira et al (2011), Farias et al (2017,Macedo e Nonato (2018),Goetz et al (2019),Almeida et al (2020),Andrade et al (2021),Moraes et al (2021). No Ceará, ainda são escassos os trabalhos tratando somente das samambaias e licófitas, em comparação com os estados da região Sul e Sudeste, onde possuem os maiores estudos e os maiores fragmentos de Mata Atlântica, como podemos observar nos estudos realizados porPaula (1993),Zárate (2005), Paula-Zárate et al (2007), Silvestre et al (2019) e Silvestre (2018).…”
