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.

Resumo

A Floresta Atlântica Nordestina (FAN) possui um histórico de intensa perda e fragmentação de hábitats. Neste contexto, o conhecimento das espécies a partir das áreas ainda remanescentes é urgentemente requerido, constituindo a ferramenta básica para estudos futuros e estratégias conservacionistas. Aqui, apresentamos o inventário de samambaias e licófitas a partir da Reserva Particular do Patrimônio Natural - RPPN Pedra D’Antas, situada em área da FAN. A área de estudo associada a RPPN Frei Caneca constitui a Serra do Urubu, conhecida como um hot-spots de diversidade para diversos grupos biológicos na FAN. Registramos 74 espécies de samambaias, distribuídas em 17 famílias e 46 gêneros. As famílias mais diversas foram Pteridaceae (17 espécies), Polypodiaceae (14 spp.), Dryopteridaceae (nove spp.) e Thelypteridaceae (sete spp.). As licófitas foram representadas por quarto espécies, duas famílias e dois gêneros. Apresentamos um novo registro para o Nordeste brasileiro, Serpocaulon hirsutulum. A área possui um número expressivo de espécies, algumas das quais com destruição restrita a FAN (e.g. Megalastrum umbrinum). A partir da riqueza da área de estudo associada a outro inventário realizado na RPPN Frei Caneca (138 spp.), corroboramos a Serra do Urubu como um hot-spot de diversidade para as samambaias e licófitas na FAN.

Introduction

The number of floristic inventories for the various ecosystems of the Brazilian territory has grown in recent decades, as evidenced by the Forzza et al. 2010FORZZA, R.C., et al. 2010. Catalogue of the Plants and Fungi of Brazil.. However, thorough knowledge of the high plant diversity occurring in the country, which is highly threatened by many anthropogenic pressures, still requires more efforts. Inventories are the means by which such knowledge is achieved (Magurran 2004MAGURRAN, A.E. 2004. Measuring biological diversity. Blackwell, London.). They allow recognizing the areas that hold highest richness as well as update the floras and biogeographical patterns of distribution of species (e.g. new records of species and/or species with restricted distribution), which represents key information for several biological studies and future conservation strategies (see Prado & Hirai 2011PRADO, J. & HIRAI, R.Y. 2011. Checklist das licófitas e samambaias do Estado de São Paulo, Brasil. Biota Neotrop. 11(1a): 161-190. http://dx.doi.org/10.1590/S1676-06032011000500012 (last access at 20/01/2017).

Pteridófitas de Santa Catarina: um olhar sobre os dados do Inventário Florístico Florestal de Santa Catarina, Brasil. Acta Bot. Bras. 26(2): 421-434.), identifying forest remnants most important to conservation on a given geographic or politic scale.

The need for more inventories is stressed by the excessive loss of species caused by intense levels of degradation in Brazilian ecosystems. It is likely that some species may disappear even before registration at local, regional or national level. Particularly, the Northeastern Atlantic Forest (NAF) in Brazil (region north of the São Francisco River, covering the States of Alagoas, Pernambuco, Paraíba, Rio Grande do Norte, and enclaves in Ceará State) has a notorious scenario of intense habitat loss and fragmentation resulting from a long historical period of disturbances. Furthermore, few protected areas have been established in this biogeographical unit, which is recognized by its high vulnerability and loss of species (Tabarelli et al. 2006TABARELLI, M., SIQUEIRA FILHO, J. A. & SANTOS, A. M. M. 2006. A Floresta Atlântica ao norte do rio São Francisco. In Diversidade Biológica e Conservação da Floresta Atlântica ao Norte do Rio São Francisco (K. Pôrto, J. Almeida-Cortez & M. Tabarelli, Orgs). Ministério do Meio Ambiente, Brasília, p.25-40., Ribeiro et al. 2009RIBEIRO, M.C., METZGER, J.P., MARTENSEN, A.C., PONZONI, F.J. & HIROTA, M.M. 2009. The Brazilian Atlantic Forest: How much is left, and how is the remaining forest distributed? Implications for conservation. Biological Conservation 142(6): 1141-1153.).

The Serra do Urubu comprises two protected areas: the Private Natural Heritage Reserve (Reserva Particular do Patrimônio Nacional – RPPN) Frei Caneca and the RPPN Pedra D’Antas, and represents one of the last largest forest NAF remnants, with approximately 1000 ha. This area has high species richness and endemism, being considered a hotspot for biodiversity of flowering plants in the NAF (Melo et al. 2016MELO, A., AMORIM, B.S., PESSOA, E., MACIEL, J.R. & ALVES, M. 2016. Serra do Urubu, a biodiversity hot-spot for angiosperms in the northern Atlantic Forest (Pernambuco, Brazil). Check List 12(1): 1-25.), and one of the most important areas for bird conservation in the Neotropics (SAVE Brasil 2016SAVE BRASIL. http://www.savebrasil.org.br/ last access at (21/12/2016).
http://www.savebrasil.org.br/... ). Moreover, the RPPN Frei Caneca has the highest richness of ferns and lycophytes, the seedless vascular plant groups, ever recorded to a NAF (138 spp.) (Lopes 2003). Here, we present the inventory of the ferns and lycophytes flora of the RPPN Pedra D’Antas, where a first record of Serpocaulon hirsutulum for the northeastern Brazil is reported and the status of the Serra do Urubu as a hotspot for ferns diversity in NAF is confirmed.

Material and Methods

1. Study area

The RPPN Pedra D’Antas (8°42’14’’S – 35°51’10’’W, max. alt.: 800 m) is located in Lagoa dos Gatos (47.25% of the area), Jaqueira (6.72%) and São Benedito do Sul (46.03%) municipalities of the State of Pernambuco, northeastern Brazil. The area presents approximately 325 hectares of Open Ombrophylous Atlantic Forest in diverse stages of preservation (Figure 1). The relief of the area is hilly with flat tops, steep slopes and narrow valleys. The area has predominantly sandy-clay, yellowish red argisol soil (IBGE 1995IBGE – INSTITUTO BRASILEIRO DE GEOGRAFIA E ESTATÍSTICA. 1985. Atlas Nacional do Brasil: Região Nordeste. Relatório Técnico. IBGE, Rio de Janeiro.). There are several perennial water bodies of the Una River Basin (CPRM 2005CPRM – Companhia de Pesquisa de Recursos Minerais Serviço Geológico do Brasil. 2005. Diagnóstico do município de Lagoa dos Gatos, Pernambuco. (last access at 24/08/2016)). The local climate is tropical moist as with hot and dry summer and rainy winter, according to Koppen classification (1948)KÖPPEN, W. 1948. Climatologia. Fondo de Cultura Económica, México. The average annual rainfall is approximately 1,345 mm. The annual average temperature is 23.6°C, ranging from 18°C to 30°C (CPRM 2005CPRM – Companhia de Pesquisa de Recursos Minerais Serviço Geológico do Brasil. 2005. Diagnóstico do município de Lagoa dos Gatos, Pernambuco. (last access at 24/08/2016)).

2. Inventory

Fifteen trips were carried out from October/2011 to January/2013 to the study area. On each trip, the forest fragment was explored through systematic walks, georeferencing points with GPS and giving priority to the preferential environments for establishment of ferns and lycophytes (e.g. forest edge and interior, areas near streams and other water bodies, ravines, valleys and slopes and rocky areas). Besides the systematic exploration of these environments, random walks were also conducted to cover the most of the forest fragment area. Collection and herborization of specimens followed the usual techniques for vascular plants (Mori et al. 1989MORI, S.A., SILVA, L.A.M. & LISBOA, G. 1989. Manual de manejo do herbário fanerogâmico. Centro de Pesquisa do Cacau, Ilhéus.). Voucher specimens were incorporated into the UFP herbarium collection. Identification was carried out with aid of specialized bibliography, consultation with specialists and comparison with herborized material from the UFP herbarium determined by specialists. The classification presented follows the Pteridophyte Phylogeny Group (PPG 2016PPG 1 - The Pteridophyte Phylogeny Group. 2016. A community-derived classification for extant lycophytes and ferns. J. Syst. Evo. 54(6): 563-603.). The names of the authors of the species were abbreviated according to the Flora do Brasil (2020)FLORA DO BRASIL. 2020. http://floradobrasil.jbrj.gov.br/reflora/floradobrasil/FB128483. (last access at 12/08/2017).
http://floradobrasil.jbrj.gov.br/reflora... .

Field notes at the collection site of specimens were taken, ranking the species in the following categories: terrestrial, rupicolous, hemiepiphyte and holoepiphyte (Salvo Garcia & Verdugo 1990SALVO, A.E. & GARCIA-VERDUGO, J.C. 1990. Biogeografia numerica en pteridologia. In Taxonomia, biogeografia y conservación de pteridófitos (J. Rita, ed.). Sociedad Historia Natural Baleares-IME, Palma de Mallorea, p.115-150.). For comparison of species richness in the study area with other areas, we consulted the available inventories in the NAF. Comments about some taxa (distribution and taxonomic characteristics) were based on cited literature.

Results and Discussion

Seventy-four species of ferns (Polypodiospsida Class), representing 46 genera and 17 families were recorded in the RPPN Pedra D’Antas (Table 1). As for lycophytes (Lycopodiopsida Class), four species in two families and two genera were recorded (Table 1). The fern and lycophyte richness of the study area (79 spp.) can be considered high when contrasted to other NAF areas (Table 2). This number of species represents about 36% of the richness of ferns and lycophytes estimated for the state of Pernambuco (214 spp.) according to Prado et al. (2015)PRADO, J., SYLVESTRE, L.S., LABIAK, P.H., WINDISCH, P.G., SALINO, A., BARROS, I.C.L., HIRAI, R.Y., ALMEIDA, T.E., SANTIAGO, A.C.P., KIELING-RUBIO, M.A., PEREIRA, A.F.N., ØLLGAARD, B., RAMOS, C.G.V., MICKEL, J.T., DITTRICH, V.A.O., MYNSSEN, C.M., SCHWARTSBURD, P.B., CONDACK, J.P.S., PEREIRA, J.B.S. & MATOS, F.B. 2015. Diversity of ferns and lycophytes in Brazil. Rodriguésia 66(4): 1073-1083.. This emphasizes the relevance of preserving the area for the conservation of the studied groups.

Table 2
Ten inventories of Ferns (Polypodiopsida) and Lycophytes (Lycopodiopsida) performed Northeastern Atlantic Forest with greatest number of species recorded.

The most representative families were Pteridaceae (17 species), Polypodiaceae (14 spp.), Dryopteridaceae (nine spp.) and Thelypteridaceae (seven spp.). These families account for approximately 64% of the sampled ferns. Among the sampled families, 26% are represented by only one species. The genus Adiantum L. presented the highest specific representativeness, nine species (Table 1).

The fern and lycophyte flora of the present area is mostly composed of species common to other NAF inventoried areas (e.g. Santiago & Barros 2003SANTIAGO, A.C.P. & BARROS, I.C.L. 2003. Pteridoflora do Refúgio Ecológico Charles Darwin (Igarassu, Pernambuco, Brasil). Acta Bot. Bras. 17(4): 597-604., Xavier & Barros 2003XAVIER, S.R.S. & BARROS, I.C.L. 2003.

Richness, geographic distribution and ecological aspects of the fern community within the Murici Ecological Station in the state of Alagoas, Brazil. Acta Bot. Bras. 27(4): 788-800.). However, some taxa are not usually registered in NAF, such as Megalastrum umbrinum (Farias et al. 2015FARIAS, R.P., SANTIAGO, A.C.P., PEREIRA, A.F.N., SILVA, I.A.A. & BARROS, I.C.L. 2015. New records of Megalastrum in the northeastern Atlantic Forest. Check List 11(2): 1-3.), 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.

In addition, Serpocaulon hirsutulum was found, representing a new record for the Northeast of Brazil. The species S. hirsutulum (see characteristics in Schwartsburd & Smith 2013SCHWARTSBURD, P.B & SMITH, A. 2013. Novelties in Serpocaulon (Polypodiaceae). Bot. Res. Inst. Texas 7(1): 85-93.) has distribution restricted to the states of Minas Gerais, São Paulo (southeast) and Pernambuco (northeast). In the latter, it is recorded in two areas (i.e. Serra do Urubu): the RPPN Frei Caneca (recently determined and unpublished material) and the present studied area.

Only one exotic species was recorded in the RPPN Pedra D'Antas: Macrothelypteris torresiana. This species is native from Madagascar, Japan, Indonesia, Thailand, Malaysia, Queenslândia (Robinson et al., 2010ROBINSON, R.C., SHEFFIELD, E. & SHARPE, J.M. 2010. Problem fern: their impact and management. In Fern Ecology (K. Mehltreter, L.R. Walker & J.M. Sharpe, eds.). Cambridge University Press, New York, p.255-322.), and it is widely naturalized and often collected in Brazilian forests, particularly in the areas of the Atlantic Forest and Cerrado, according to Salino & Almeida (2015)SALINO, A. & ALMEIDA, T.E. 2015. Thelypteridaceae in Lista de Espécies da Flora do Brasil. Jardim Botânico do Rio de Janeiro..

As for the types of habitat, terrestrial species (55%) were predominant. This result supports the majority of fern and lycophyte inventories in the NAF (e.g. Santiago & Barros 2003SANTIAGO, A.C.P. & BARROS, I.C.L. 2003. Pteridoflora do Refúgio Ecológico Charles Darwin (Igarassu, Pernambuco, Brasil). Acta Bot. Bras. 17(4): 597-604., Xavier & Barros 2003XAVIER, S.R.S. & BARROS, I.C.L. 2003. Pteridófitas ocorrentes em fragmentos de floresta serrana no estado de Pernambuco, Brasil. Rodriguésia 54(83): 13-21., Santiago et al. 2004SANTIAGO, A.C.P., BARROS, I.C.L. & SYLVESTRE, L.S. 2004.

Richness, geographic distribution and ecological aspects of the fern community within the Murici Ecological Station in the state of Alagoas, Brazil. Acta Bot. Bras. 27(4): 788-800.). This pattern of predominance of terrestrial habitat can be explained by the diversity of favorable conditions promoted by this substrate, such as water availability, shade, as well as greater availability of nutrients (Sota 1971SOTA, E.R. 1971. El epifitismo y las pteridofitas en Costa Rica (America Central). Nova Hedwigia 21(2-4): 401-465.).

. The high richness recorded here for the RPPN Pedra D’Antas and reported by Lopes (2003) for the RPPN Frei Caneca supports the concept this area as a hotspot for the fern and lycophyte diversity in the NAF. As a consequence, the importance of effective protection of the area is reinforced.
