Abstract

ABSTRACT Background: Lianas are an important component of tropical forests that respond to logging disturbance. Determining liana response to selective logging chronosequence is important for understanding long-term logging effects on lianas and tropical forests. Aims: Our objective was to quantify the response of liana communities to selective logging chronosequence in a moist semi-deciduous forest in Ghana. Methods: Liana community characteristics were determined in ten 40 m × 40 m plots randomly and homogenously distributed in each of four selectively logged forest stands that had been logged 2, 14, 40 and 68 years before the surveys and in an old-growth forest stand (ca. >200 years). Results: Liana species composition differed significantly among the forest stands, as a function of logging time span, while species richness fluctuated along the chronosequence. The abundance of liana communities and of reproductive and climbing guilds was lower in the logged forests than in the old-growth forest. The ratio of liana abundance and basal area to those of trees was similar in the logged forests, but significantly lower than those in the old-growth forest. Conclusions: Logging impacts on liana community structure and functional traits were largely evident, though no clear chronosequence trends were recorded, except for species composition.
加纳湿润半落叶林藤本植物群落结构和功能特征随选择性采伐时序的变化
摘要背景:藤本植物是热带森林的一个重要组成部分,对伐木干扰具有响应作用。确定藤本植物对选择性伐木时序的反应对于理解长期伐木对藤本植物和热带森林的影响很重要。目的:我们的目标是量化加纳潮湿半落叶林中藤本植物群落对选择性采伐时序的反应。方法:在调查前2年、14年、40年和68年被选择性砍伐的4个林分中的每一个林分和一个老林分(约>200年)中随机均匀分布的10个40 m×40 m的样地中测定莲属群落特征。结果:不同林分藤本植物的物种组成存在显著差异,是伐木时间跨度的函数,而物种丰富度则随时间序列而波动。砍伐森林中藤本植物群落以及繁殖和攀爬群落的丰度低于老森林。砍伐森林中藤本植物的丰度和基底面积与树木的比值相似,但明显低于老林。结论:采伐对藤本植物群落结构和功能性状的影响非常明显,但除物种组成外,没有记录到明确的时序趋势。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
