Abstract

Diversity, taxonomy and distribution for Brazilian states of the families Bartramiaceae, Brachytheciaceae, Bryaceae, Calymperaceae, Fissidentaceae, Hypnaceae and Leucobryaceae (Bryophyta) of the Scientific Station Ferreira Penna, Caxiuanã, Pará, Brazil) ABSTRACTThe inventory of the species of mosses (Bryophyta) was conducted in the Scientific Station Ferreira Penna, municipality of Melgaço, state of Pará. This station possesses 85% of its area of well conserved, terra-firme vegetation. Although the phanerogams are relatively well studied, the mosses are only now moving forward with this work. Besides inventorying the species of mosses inhabiting the area, other objectives are to expand knowledge regarding the geographical distribution of the species reported for the area, and to register the substratum type and ecosystem where they occur. There were identified 84 species, 37 genera and 19 families. This work is part of a series of studies accomplished with the mosses of ECFPn, just treating the 47 species belonging to the families Bartramiaceae, Brachytheciaceae, Bryaceae, Calymperaceae, Fissidentaceae, Hypnaceae and Leucobryaceae. For each táxon they were mentioned place-type, herbarium, references of descriptions, comments regarding morphological characteristics, Brazilian geographical distribution and examined material.

“…The genera Lejeunea, Cheilolejeunea, Ceratolejeunea, Fissidens, Calymperes and Syrrhopodon are often the most representative in Pará (Santos and Lisboa, 2008;Moraes and Lisboa, 2009;Brito and Ilkiu-Borges, 2013;Moura et al, 2013), and therefore this result was also predictable.…”

“…Leucobryum martianum, Lepidopilum surinamense and L. scabrisetum are characteristic epiphytes of humid tropical forest Santos and Lisboa, 2008;Moraes and Lisboa, 2009;Moura et al, 2013), and the later one seems to be confined to this type of environment (Florschütz-de Waard, 1986). In Pará, only L. surinamense was found in canga vegetation, an open and dry environment (Moraes and Lisboa, 2006).…”

“…No Estado do Pará, nos últimos dez anos, tem aumentado os estudos taxonômicos que incluem tanto a fl ora de musgos quanto a de hepáticas. Estes, constantemente acresceram novos registros para o Estado, país e para a ciência, principalmente de espécies de hepáticas, a exemplo dos trabalhos de Ilkiu-Borges & Lisboa (2002b, c, 2004, Alvarenga et al (2007), Moraes & Lisboa (2009), Brito & Ilkiu-Borges (2012, Moura et al (2012).…”

“…Steph., exemplos de espécies que foram pouco frequentes nas áreas de estudo e que também são pouco coletadas no Estado, mas já foram reportadas por outros estudos no Estado (Tavares et al 2006, Moraes & Lisboa 2009, Brito & Ilkiu-Borges 2013.…”
