Survey of bryophytes in Serra da Canastra National Park, Minas Gerais, Brazil

Abstract

Serra da Canastra National Park is located in southwestern Minas Gerais State and contains several phytophysiognomies of the Brazilian Cerrado. To date, no study on bryophytes has been conducted in this area and the present study is the fi rst to be carried out in this major biological reserve of Cerrado located on the Brazilian Plateau. Th is study found 289 species of bryophytes, including mosses, liverworts, and one species of hornwort, representing fourtyone Brazilian endemic species and 56 new records for Minas Gerais State. Most species are widely distributed in Brazil, with only 16% having restricted distributions. Regarding worldwide distribution, 31% are Neotropical. Lejeuneaceae had the highest species richness among liverwort families with 53 species, whereas Sphagnaceae had the highest richness among moss families with 26 species. Phaeoceros laevis was the only hornwort species found in the park. Th is study contributes to the understanding of bryophyte species richness and distribution, and provides the worldwide and Brazilian distribution of the bryophyte fl ora of Serra da Canastra National Park, an important center for biodiversity conservation.

Caracterización morfo-ecológica y composición de briofitos en pastizales rocosos en el Cerrado Brasileño

“…The number of species found is 16% of the 289 species cited for Serra da Canastra National Park (Carmo & Peralta, 2016), 6% of 773 bryophytes cited for Minas Gerais state and 12% of 397 bryophytes cited for Brazilian Cerrado (Flora do Brasil, 2020 em construção).…”

“…Among the areas of high altitudes for Minas Gerais state, this family is cited in literature as high richness (Yano & Carvalho, 1995;Yano & Peralta, 2009;Yano & Peralta, 2011a;Carmo & Peralta, 2016) and constantly found in mountainous regions (Gradstein et al, 2001).…”

“…The bryophytes species considered exclusive of the rock fields represent approximately 16% of species found for the total area of the Park (Carmo & Peralta, 2016). In other words, due to a drier and exposed environment (Rapini et al, 2008) the rock fields do not have a high richness if compared to wetter environments of Cerrado sensu lato as gallery forests areas, slope forests, areas of waterfalls and ombrophilous rain forests.…”

“…Bryophytes floristic characterization for rocky fields in Brazil are reported by Yano & Carvalho (1995) who found 46 species of bryophytes in Serra da Piedade; Yano & Peralta (2009) with 42 species in the mountains of Serra de Grão-Mogol; Yano & Peralta (2011a) with 114 species in Serra de São José at the city of Tiradentes; Yano & Peralta (2011b) with 237 species in different vegetation types of Serra do Cipó; Luizi-Ponzo et al (2013) who found 209 species for Ibitipoca State Park and recently Carmo & Peralta (2016) published the floristic survey of 289 species found in Serra da Canastra National Park, all these works were carried out for Minas Gerais state. Besides these, we also found Bastos et al (2000) who presented a list of 65 taxa and Valente et al (2013) found 212 species, both in Chapada Diamantina, in the Bahia state.…”
