摘要

本研究旨在描述哥伦比亚亚马逊河流域Zafire生物站腐烂原木上苔藓植物群落的特征。我们在两种类型的森林(陆地林地和漫滩林地)中选取了20个不同分解状态的树干上的100个样地。已报道地苔类81种，藓类39种，隶属于地苔类33属，苔类22科，地苔类9科，苔类12科。哥伦比亚登记了四个新物种，哥伦比亚亚马逊地区登记了25个，亚马逊省登记了41个。在丰富度方面，洪泛区比陆生森林表现出更高的价值。但两种林分间无显著差异(Kruskal Wallis X2c = 0.199, X2t = 3.81)。洪泛区(shannon = 3.93)的多样性高于陆生森林(shannon = 3.67)。两种林分苔藓植物群落组成差异较大，相似度为40%。在生物站的两种类型森林的区系研究中，最常见的科是Lejeuneaceae，占苔藓植物种类总数的55.5%和37.5%。

BRIÓFITOS DE TRONCOS EN DESCOMPOSICIÓN DE LA ESTACIÓN BIOLÓGICA EL ZAFIRE, AMAZONAS-COLOMBIA

The present study aims to characterize the bryophyte community on rotten logs in the Zafire biological station, Amazonas-Colombia. We sampled 100 plots on 20 trunks with different states of decomposition in two types of forest (terra firme and floodplain). 120 species are reported, 81 liverworts and 39 mosses, belonging to 55 genera (33 liverworts and 22 mosses) and 21 families (nine liverworts and 12 mosses). Four new species are registered for Colombia, 25 for the Colombia Amazon, and 41 for the department of Amazonas. In terms of richness, the floodplain presented a higher value than the terra firme forest. However, no significant difference was found between the two types of forests (Kruskal Wallis X2c = 0.199, X2t = 3.81). Diversity was higher in the floodplain (Shanon = 3.93) compared to the terra firme forest (Shanon = 3.67). The composition of the bryophyte communities shows differences between the two types of forests (similarity equal to 40 %). In the floristic study of the two types of forests of the biological station, the most common family was Lejeuneaceae, representing 55.5 % of the liverworts sampled and 37.5 % of the total of the bryophyte species.

期刊介绍： Bothalia: African Biodiversity & Conservation is published by AOSIS for the South African National Biodiversity Institute (SANBI) and aims to disseminate knowledge, information and innovative approaches that promote and enhance the wise use and management of biodiversity in order to sustain the systems and species that support and benefit the people of Africa. The journal was previously published as Bothalia, and had served the South African botanical community since 1921. However the expanded mandate of SANBI necessitated a broader scope for the journal, and in 2014, the subtitle, African Biodiversity & Conservation was added to reflect this change.
