Survey of the bryophytes of a gallery forest in the National Park of Serra do Cipó, Minas Gerais, Brazil

Abstract

Serra do Cipó has attracted the interest of many researchers over the years because of its unique characteristics, particularly the fact that the site represents the transition between Cerrado and Atlantic Forest. The study area of Serra do Cipó is located along a gallery forest "córrego Três Pontinhas, " at 19°16'00" S and 43°32'49" W and an altitude of 1,188 m. The objective of this study was to survey the Division Bryophyta in a gallery forest within the National Park of Serra do Cipo, Minas Gerais. Collections were made during the months of November 2009 and July 2011. We found 15 families, 26 genera, 43 species, and 4 varieties of mosses. The families with the largest number of species were Leucobryaceae (10), Sematophyllaceae (9), and Calymperaceae (6). Other families included Fissidentaceae (3), Bryaceae, Pylaisiadelphaceae, Pottiaceae, and Orthotrichaceae (2 spp. each); Brachytheciaceae, Cryphaeaceae, Fabroniaceae, Helicophyllaceae, Hypnaceae, Polytrichaceae, and Sphagnaceae had only 1 sp. each. Three new records for the state of Minas Gerais were found: Acroporium caespitosum, A. longirostre, and Colobodontium vulpinum.

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

“…In their study focusing on gallery forests of Serra do Cipó, Souza & Câmara (2015) also observed a preference for corticicolous substrates and explanained this finding on the abundance of this substrate in the area, but concluded that ecological studies are needed to verify this hypothesis. Following this reasoning, the large amount of rupicolous species in Serra da Canastra National Park is likely due to the presence of many rocks, especially in areas near waterfalls and in rocky fields, since the methodology of collection was the same for all vegetation types.…”

“…However, most of the species (62) found in the park are considered exclusive to the Atlantic Forest domain, such as Bryum caespiticium, Squamidium brasiliense, Syrrhopodon tortilis and Wijkia flagellifera for Bryophyta (Souza & Câmara 2015) and Bazzania heterostipa, Calypogeia grandistipula, Frullania schaefer-verwimpii and Lejeunea cristulata for Marchantiophyta (Yano 2008).…”

“…Floristic surveys conducted in areas of Minas Gerais that are similar to Serra da Canastra include Yano & Carvalho (1995) who found 46 species in Serra da Piedade; Yano & Peralta (2009) who found 42 species of mosses and hepatics in the Grão-Mogol mountains; Yano & Peralta (2011a) found 114 species in Serra de São José at the city of Tiradentes; Yano & Peralta (2011b) found 237 species in Serra do Cipó; Luizi-Ponzo et al (2013) found 209 species in Ibitipoca State Park and, recently, Souza & Câmara (2015) who studied the mosses of gallery forest in Serra do Cipó National Park. Th ese works contain relevant fl oristic data and are useful in the identification of some species.…”

Briófitas na Estação Ecológica da Universidade Federal de Minas Gerais, Brasil

“…4). A predominância de briófitas em tronco vivo também é relatada por diferentes autores como Aquino et al (2015) e Sousa & Câmara (2015) estudando matas de galeria no Cerrado brasileiro; por Holz et al (2002) e Holz & Gradstein (2005 em florestas montanas na Costa Rica; por Alvarenga & Lisboa (2009), Ilkiu-Borges et al (2009, Moura et al (2013) e Brito & Ilkiu-Borges (2014 em ecossistemas amazônicos; e Costa (1999) em florestas de terras baixas no sudeste do Brasil. Troncos vivos, assim como troncos em decomposição, são substratos favoráveis à colonização de briófitas pois retêm elevada umidade e geralmente estão disponíveis no ambiente, sendo colonizados por diferentes espécies de briófitas, desde a base até o dossel superior (Holz et al 2002, Holz & Gradstein 2005.…”
