Abstract:We present a checklist of the ferns and lycophytes from the Cerrado State Park, Jaguariaíva, Paraná, Brazil. This region represents the southernmost limit of Cerrado vegetation in Brazil. The park is located along the Devonian Escarpment, one of the most iconic geological formations in southern Brazil. The remnants of Cerrado in Paraná are relics of a colder and drier climate that occurred during the Last Glacial Maximum, about 5,600 years ago. They are now surrounded by natural grasslands and Araucaria Forest… Show more
“…1), predominantly in the understory, where pteridophytes occupy several microenvironments. A predominance of pteridophytes in wet forests (Mata de galeria and Mata cCiliar) has been reported in other studies in the Cerrado (Colli et al 2004;Fernandes et al 2022;Kreutz et al 2016;Miguez et al 2013;Nunes & Labiak 2021). Compared to those studies, the species number reported here is relatively low, considering the expanded size of the EESGT.…”

“…The lower species richness in the Cerrado, which is dominated by open habitats under a seasonally dry climate, reflects the ecological preference of most pteridophyte groups for moist and forested areas. Nevertheless, many species can be found in wet environments associated with water bodies, such as gallery forests and swamps (Colli et al 2004;Fernandes et al 2022;Kreutz et al 2016;Miguez et al 2013;Nunes & Labiak 2021). On the other hand, some dry-adapted lineages have successfully colonized open habitats of the Cerrado, such as species of Anemia (Hietz 2010;Mickel 2016), a genus especially diverse in Central Brazil (Mickel 2016).…”
This study contributes to the flora of ferns and lycophytes, also referred to as pteridophytes, from the Estação Ecológica Serra Geral do Tocantins (EESGT), which is part of the Jalapão region in Tocantins. Although Jalapão is one of the largest protected areas in the Cerrado vegetation of Northern Brazil, its biodiversity has, thus far, been poorly reported in the literature. Therefore, fieldwork was recently carried out at EESGT in different habitats. Our collections and data from digital repositories included 31 ferns and four lycophyte species belonging to 20 genera of 15 families. Despite occupying only a small fraction of the landscape, forests concentrate most pteridophyte diversity, reinforcing their importance for the conservation of this group within the Cerrado. Eleven species are new records for Tocantins, one is new for Bahia, and one was recently described (Anemia areniticola). In addition to a list of all taxa, we provide illustrations and an identification key to encourage further studies on this often-neglected component of Cerrado flora.
