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.

“…In particular, in Piauí, the Brazilian government created the Sete Cidades National Park (PNSC), covering an area of 6,221 ha, aiming to study and protect the diversity of water, vegetation, and soil resources (IBDF, 1979). During the last ten years, geomorphological and quantitative surveys of vegetation and animals have been conducted (Digby et al 1996;Cavalcanti and Mobin, 2001;Castro et al, 2002).…”

Biological properties of disturbed and undisturbed Cerrado sensu stricto from Northeast Brazil

et al. 2017

View full text Add to dashboard Cite

The aim of this study was to measure soil microbial biomass and soil surface fauna in undisturbed and disturbed Cerrado sensu stricto (Css) from Sete Cidades National Park, Northeast Brazil. The following sites were sampled under Cerrado sensu stricto (Css) at the park: undisturbed and disturbed Css (slash-and-burn agricultural practices). Total organic and microbial biomass C were higher in undisturbed than in disturbed sites in both seasons. However, microbial biomass C was higher in the wet than in the dry season. Soil respiration did not vary among sites but was higher in the wet than in the dry season. The densities of Araneae, Coleoptera, and Orthoptera were higher in the undisturbed site, whereas the densities of Formicidae were higher in the disturbed site. Non-metric multidimensional scaling analysis separated undisturbed from disturbed sites according to soil biological properties. Disturbance by agricultural practices, such as slash-and-burn, probably resulted in the deterioration of the biological properties of soil under native Cerrado sensu stricto in the Sete Cidades National Park.Keywords: soil microbial biomass, soil fauna, sustainability, soil disturbance. Propriedades biológicas de Cerrado sensu stricto preservado e não preservado do Nordeste do BrasilResumo O objetivo do estudo foi avaliar as propriedades biológicas do solo em área de Cerrado sensu stricto preservadas e não preservadas do Parque Nacional de Sete Cidades, Nordeste do Brasil. Os seguintes sites sob Cerrado sensu stricto (Css) foram avaliados: preservado (UND) e não preservado (DIS). O C orgânico total e da biomassa microbiana foram maiores na área preservada do que na não preservada em ambas estações seca e chuvosa. Entretanto, o C da biomassa microbiana foi maior na estação chuvosa do que na seca. A respiração do solo não variou entre as áreas, mas foi maior na estação chuvosa. As densidades de Araneae, Coleoptera e Ortoptera foram maiores na área preservada, enquanto as densidades de Formicidae foram maiores na área não preservada. A analise de escalonamento não-métrico separou a área preservada da não-preservada de acordo com as propriedades biológicas. Os distúrbios no solo pelas atividades agrícolas, como corte-e-queima, resultaram na deterioração das propriedades biológicas do Cerrado nativo no Parque Nacional de Sete Cidades.Palavras-chave: biomassa microbiana do solo, fauna do solo, sustentabilidade, distúrbio no solo.

“…Therefore, in Brazil as a whole, systematic floristic studies of bryophytes have most often been conducted in forests, including those in the states of Rio de Janeiro (Costa 1999;Costa & Lima 2005;Molinaro & Costa 2001;Santos & Costa 2010a, 2010b, Espírito Santo (Costa & Silva 2003;Yano 2005), São Paulo (Visnadi 2005;Visnadi & Vital 2000;Peralta & Yano 2005), Pernambuco (Pôrto 1990(Pôrto , 1992Germano & Pôrto 1996;Campelo & Pôrto 2007;Alvarenga & Pôrto 2007), Alagoas (Silva & Pôrto 2009) and Bahia (Valente & Pôrto 2006;Bastos & Valente 2008;Valente et al 2009). Studies of bryophytes in the cerrado have been conducted in the states of São Paulo (Egunyomi & Vital 1984;Visnadi 2004), Bahia (Vilas Bôas- Bastos & Bastos 1998) and Piauí (Castro et al 2002), as well as in the Federal District of Brasília (Câmara & Costa 2006;Câmara 2008aCâmara , 2008b. In the campos rupestres, bryophytes have been studied in the state of Minas Gerais-in the Serra do Cipó (Yano 1987), Serra da Piedade (Yano & Carvalho 1995) and Grão Mogol (Yano & Peralta 2009)-and in the state of Bahia, specifically within the Chapada Diamantina ecoregion (Harley 1995;Bastos et al 1998aBastos et al , 2000.…”

The Chapada Diamantina ecoregion is within the caatinga (shrublands) biome of Brazil. Environmental factors determine the phytophysiognomies that distinguish the ecoregion from the surrounding areas. This study aimed to investigate the distribution of bryophyte flora in this ecoregion, by phytophysiognomy and elevational zone. Analyzing specimens we collected from five municipalities in the region, together with specimens (previously collected from the region) in herbaria, we identified 400 taxa. The phytophysiognomies that presented the highest species richness and the greatest numbers of exclusive taxa were forests and campos rupestres (dry, rocky grasslands), which respectively accounted for 51% and 40% of the taxa, compared with only 5% and 4%, respectively, for the caatinga and cerrado (savanna). Species richness and the numbers of exclusive taxa were highest in the lower and upper montane zones. There was a predominance of neotropical taxa and a significant number of disjunct species found in Brazil and in the Andes region. We conclude that the Chapada Diamantina region is an important center of bryophyte diversity, harboring not only a great number of species overall but also a considerable number of species exclusive to the region, primarily in forests and campos rupestres at elevations above 800 m.
