“…1, the most widely colonized substrate was tree trunk (living or decomposing), supporting data in the literature on tropical forests, in which these are reported to be the substrates most widely used by bryophytes, due to their abundance and ability to retain moisture (Pócs 1982;Richards 1984;Germano & Pôrto 1998). This result was expected, because this pattern was the same as that reported in other studies of bryophytes in the Amazon, including those in northeastern Pará (Santos & Lisboa 2003Lisboa & Santos 2005;Lisboa & Tavares 2008;Ilkiu-Borges et al 2009;Tavares et al 2014).…”

The bryophytes of Gurupi Biological Reserve represent an important component of the biodiversity of the Amazon in the Brazilian state of Maranhão. This study aimed to investigate the richness of bryophytes (Marchantiophyta and Bryophyta) from Gurupi Biological Reserve and compare it with that found in other surveys conducted in Maranhão and in the northeastern part of the state of Pará, because the latter shows similarities with the study area in terms of vegetation, geography, demography, and history of occupation. We recorded 983 occurrences of bryophytes (549 Marchantiophyta and 434 Bryophyta) corresponding to 62 species (43 liverworts and 19 mosses), 39 genera, and 12 families. Of those 62 species, 25 have previously been collected from all regions of Brazil, two are restricted to two regions, and four are restricted to the northern (Amazon) region. The bryophyte species identified within the reserve correspond to 28.9% of the known bryophytes in Maranhão and 31.3% of the known bryophytes in northeastern Pará, the reserve therefore more closely resembling the latter area. The exclusively Amazonian elements found in the reserve underscore their affinity for this biome and their presence in the state of Maranhão. The importance of this conservation area to Maranhão and to the Amazon region of the state is confirmed by the high number of new records for the state (41 species), five of which are also new records for northeastern Brazil.

“…Quanto aos substratos, Richards (1984) e Germano & Pôrto (1998), afirmam que nas florestas tropicais úmidas, os troncos vivos seguidos por troncos mortos, são os preferidos para o estabelecimento das briófitas. Isso pode ser observado nos resultados encontrados (Tab.…”

RESUMO Foi realizado um estudo dos musgos ocorrentes em diferentes ecossistemas da microrregião do Salgado Paraense, visando determinar a riqueza, registrar os tipos de ecossistemas e substratos de ocorrência das espécies, identificar algumas destas como indicadoras de ambientes perturbados e ampliar o conhecimento da brioflora do estado do Pará. Foram registradas 38 espécies de musgos, distribuídas em 21 gêneros e 11 famílias. A riqueza de espécies foi relativamente baixa, levando-se em consideração a grande quantidade de amostras analisadas (558). Calymperes afzelii, C. erosum, C. lonchophyllum, C. palisotii, Octoblepharum albidum var. albidum, O. pulvinatum, Sematophyllum subsimplex, Splacnobryum obtusum e Taxithelium planum foram as que apresentaram melhor adaptação a condições adversas. Sugere-se que estas espécies podem ser potencialmente utilizadas como indicadoras de ambientes perturbados. Entretanto, todas as espécies ocorrentes nos oito municípios desta microrregião estão adaptadas a um complexo de fatores ambientais e encontram as condições necessárias e favoráveis à sua manutenção e reprodução.

“…Tropical rainforests are rich in epiphyte bryophytes due to high humidity levels (Richards 1954, 1984, Uniyal 1999, Germano and Pôrto 1998, Valente and Pôrto 2006, Santos and Costa 2008. One of the intrinsic characteristics of the Amazonian climate is the wide variation in its rainfall regime (Souza et al 2009).…”

This study aimed to compare the richness and composition of the epiphytic bryoflora between várzea and igapó forests in Caxiuanã National Forest, Brazilian Amazon. Bryophytes were collected on 502 phorophytes of Virola surinamensis. Average richness per phorophyte and composition between forests and between dry and rainy periods was tested by two-way analysis and by cluster analysis, respectively. In total, 54 species of 13 families were identified. Richness was greater in igapó forest (44 species) compared to várzea forest (38 species). There was no significant difference in the number of species between the studied periods. Cluster analysis showed the bryoflora composition was different between várzea and igapó, but not between dry and rainy periods. Results did not corroborate the hypothesis that várzea forests harbor higher species richness than igapó forests.
