摘要

严格塞拉多(巴西热带稀树草原塞拉多地区的一种地貌)每年都会发生火灾。关于该地貌附生植物群落的数据很少，对火灾对其结构和组成影响的评估也很少。本研究旨在描述巴西东南部塞拉多地区的维管附生植物群落结构及其与光合植物的关系。研究发现，上层附生植物的丰度最高(65%的个体分布在3 m以上)，3种通才种(绿叶莲(Tillandsia streptocarpa)、T. recurvata和叶兰(Epiphyllum phyllanthus))占优势地位，表明火对附生植物群落的结构和组成有影响。

OUT OF THE FRYING PAN INTO THE FIRE: THE COMMUNITY STRUCTURE OF EPIPHYTES IN BRAZILIAN SAVANNA AFTER THE PASSAGE OF FIRE

Cerrado sensu stricto (a physiognomy of the Cerrado domain, the Brazilian savanna) is subject to the annual occurrence of fire. Data on the epiphytic community in this physiognomy is scarce, as is evaluation of the influence of fire on its structure and composition. The aim of this study was to describe the structure of the vascular epiphyte community and its relationships with phorophytes in the Cerrado domain, Southeast Region of Brazil, after the passage of fire. We found the greatest abundance of epiphytes in the upper strata (65% of the individuals occurring above 3 m in height) and the dominance of three generalist species (Tillandsia streptocarpa, T. recurvata and Epiphyllum phyllanthus), suggesting that fire has an influence on the structure and composition of the epiphytic community.

期刊介绍： Edinburgh Journal of Botany is an international journal of plant systematics covering related aspects of biodiversity, conservation science and phytogeography for plants and fungi. The journal is a particularly valued forum for research on South East and South West Asian, Sino-Himalayan and Brazilian biodiversity. The journal also publishes important work on European, Central American and African biodiversity and encourages submissions from throughout the world. Commissioned book reviews are also included. All papers are peer reviewed and an international editorial board provides a body of expertise to reflect the wide range of work published and the geographical spread of the journal’s authors and readers.
