The aim of this study is to investigate the richness and composition of the bryophytes of two Municipal Natural Parks in Amapá, eastern Amazon. Bryophytes were collected in the Arivaldo Gomes Barreto Municipal Natural Park (AGBMNP), Macapá municipality, and Cancão Municipal Natural Park (CMNP), Serra do Navio municipality, in October 2010 and October 2012, respectively. Ten plots of 10 x 10 m were established in each park for sampling, and, in addition, random collections were made, in order to maximize the knowledge on the local bryophyte flora. In total, 53 species were identified in AGBMNP, and 110 species in CMNP. The results shown a lower richness in AGBMNP than in CMNP, which may be related to the own size of each park, the level of conservation, and its localization. In terms of abundance, the neotropical pattern and the species locally rare were most representative in both parks, however, the floristic composition diverged. The AGBMNP is composed mostly by generalist species, while the CMNP by both generalists and shade specialists. The present study recorded 54% of the known bryophyte flora of Amapá, 63 new records for the state and, in addition, three new records for the North region of Brazil.
本研究的目的是调查亚马孙东部阿马帕州两个市级自然公园中苔藓植物的丰富度和组成。2010年10月和2012年10月，分别在马卡帕市的阿里瓦尔杜·戈麦斯·巴雷托市级自然公园（AGBMNP）和纳维奥山 Serra do Navio 市的坎卡奥市级自然公园（CMNP）采集苔藓植物。在每个公园设立了10个10×10米的样地进行采样，此外还进行了随机采集，以最大限度地了解当地苔藓植物区系。AGBMNP共鉴定出53种，CMNP共鉴定出110种。结果表明，AGBMNP的丰富度低于CMNP，这可能与每个公园自身的面积、保护水平及其地理位置有关。在丰度方面，新热带区系模式和当地稀有种在两个公园中最具代表性，然而，植物区系组成有所不同。AGBMNP主要由广布种组成，而CMNP则由广布种和喜阴种组成。本研究记录了阿马帕州已知苔藓植物区系的54%，该州有63个新记录，此外，巴西北部地区还有3个新记录。
