Ferns and lycophytes from Jaú, São Paulo, Brazil

Abstract

This work presented the inventory of ferns and lycophytes of Jaú, São Paulo state. Sixty-eight species of ferns and one of lycophyte were recorded, distributed in 16 families and 32 genera. The richest families were Pteridaceae and Thelypteridaceae with 15 species each, Polypodiaceae (7spp.), Blechnaceae and Dryopteridaceae (5 spp. each). The most common guild of life form was terrestrial herbs with 57 species, followed by epiphytes (6 spp.), arborescent, aquatic and lithophytes (2 spp. each) and hemiepiphytes and scandents with one species each. The analysis of the geographical distribution showed that 46% of the species (32 spp.) occur in the Neotropics, 20 species occurs in Southern America, eight are endemic of Brazil, five pantropical and four are exotic. This study can further collaborate in the protection and preservation of the few remnants which represent probably the last areas where some species of these groups of plants occurring in the municipality.

An illustrated guide of ferns and lycophytes from Carambeí, PR, Brazil

“…2). The richest fern families found in Carambeí agree with several studies performed in the Atlantic Rain Forest, which constantly cite the following as the most diverse families, regardless of the order, Polypodiaceae, Thelypteridaceae, Pteridaceae, Dryopteridaceae, Aspleniaceae, Blechnaceae and Hymenophyllaceae (see Salino 1996;Salino & Joly 2001;Mynssen & Windisch 2004;Salino et al 2005;Nóbrega & Prado 2008;Gasper & Savegnani 2010;Matos et al 2010;Lautert et al 2015;Mazziero & Nonato 2015;. It is also true for other Brazilian biomes; Prado et al (2015) suggest that these families are the most diverse in Brazil and as well as Tryon & Tryon (1982) in the Neotropics.…”

“…Families = the three richest families, Genera = the most representative genera, Epiphytes = number of species, Endemism = percentage of species endemic to Brazil. the biome (Mynssen & Windisch 2004;Salino et al 2005;Xavier & Barros 2005;Nóbrega & Prado 2008;Zuquim et al 2008;Gasper & Sevegnani 2010;Matos et al 2010;Fernandes et al 2012;Souza et al 2012;Salino et al 2013;Mazziero & Nonato 2015; the same way in Carambeí and other studies carried out in the inlands of Paraná (Tab. 2) Michelon & Labiak 2013;Lautert et al 2015).…”

“…Epiphytes were the second guild in number of species in Carambeí and in the other inland regions of Paraná (Tab. 2) Michelon & Labiak 2013;Lautert et al 2015) as well in other areas of Atlantic Rain Forest domain (Salino 1996;Salino & Joly 2001;Mynssen & Windisch 2004;Nóbrega & Prado 2008;Gasper & Savegnani 2010;Matos et al 2010;Mazziero & Nonato 2015;Lautert et al 2015).…”

“…1). Generally these areas shelter a high number of species compared with other phytophysiognomies in the inlands as seen in some studies in São Paulo state by Salino (1996), Salino & Joly (2001), Nóbrega & Prado (2008) and Mazziero & Nonato (2015).…”

Samambaias e licófitas de um remanescente de floresta paludosa no interior do Estado de São Paulo, Brasil

“…Trabalhos desenvolvidos nestas áreas, com estas plantas, estão geralmente associados com a amostragem de outros tipos de fitofisionomias, como floresta estacional semidecidual ou cerrado. Dentre eles, destacam-se Salino & Joly (2001) para a bacia do Rio Jacaré-Pepira, Nóbrega & Prado (2008) para o Jardim Botânico Municipal de Bauru e Mazziero & Nonato (2015) para o Município de Jaú. Portanto, estudos realizados neste tipo de fitofisionomia, exclusivamente com samambaias e licófitas, tornam-se relevantes uma vez que a água é importante na distribuição e diversidade destes grupos de plantas (Poulsen 1996), sendo também um elemento fundamental para seu ciclo de vida (Windisch 1992a).…”
