The ecological impact of lianas in the edges of tropical forest areas is widely recognised; however, the edge influence on the liana community and its relationship with trees in biomes of open vegetation require further evaluation. We compared the following parameters between edges and interiors in a remnant of woody cerrado: (i) the structure of liana and tree communities (abundance, basal area and species richness and composition); (ii) the influence of microenvironmental factors on the abundance and basal area of lianas and trees; and (iii) the relationship between lianas and their host trees. We collected data from plots placed in the edge and interior (100 m distance from the edges) at two cardinal orientations (south and east) of our study site. Our results showed that (i) lianas had greater absolute and per tree host abundances in the edges, while the trees showed greater abundance and lower basal area in the interiors; (ii) there was a positive edge effect on the diversity of lianas but not of trees, with a greater diversity of lianas in the edges, while the interiors showed only a subset of the liana species recorded at the edges; (iii) the edge effect was more pronounced (less tree abundance with a larger basal area and greater abundance of lianas) on the south‐facing than on the east‐facing edges; and (iv) the microenvironmental factors analysed did not influence the general pattern of abundance and the basal area of trees and lianas. We conclude that, in the remnant of cerrado studied, the edges influenced the liana community, increasing the species richness, abundance and host occupancy. The impact of the greater diversity and abundance of lianas in the edges should be considered in the management and conservation plans of woody cerrado ecosystems.

塞拉多稀树草原残余物对藤本植物和树木的对比边缘效应

人们普遍认识到藤本植物对热带森林地区边缘的生态影响。然而，对藤本植物群落的边缘影响及其在开放植被生物群落中与树木的关系尚需进一步评估。我们比较了残留的木质木塞拉多的边缘和内部之间的以下参数：（i）藤本植物和树木群落的结构（丰度，基础面积以及物种的丰富度和组成）；（ii）微环境因素对藤本植物和树木的丰度和基础面积的影响；（iii）藤本植物与其寄主树之间的关系。我们从位于研究地点两个基本方向（南边和东边）的边缘和内部（距边缘100 m的距离）中的地块收集了数据。我们的结果表明，（i）藤本植物在边缘具有更高的绝对绝对值和每棵树寄主丰度，树木的内部空间更大，基础面积更低；（ii）对藤本植物的多样性具有积极的边缘效应，但对树木没有影响，边缘上的藤本植物多样性更大，而内部仅在边缘处记录到藤本植物物种的一个子集；（iii）与朝东的边缘相比，朝南的边缘效应更为明显（树木丰度较小，基础面积更大，藤本植物的丰度更大）；（iv）所分析的微环境因素不影响树木和藤本植物的总体丰度模式和基础面积。我们得出的结论是，在研究的cerrado残余物中，边缘影响了藤本植物群落，从而增加了物种的丰富度，丰度和寄主的占有率。
