Abstract

ABSTRACT Background Montes de María is the best-preserved tropical dry forest fragment in the Colombian Caribbean, making it a good model to relate environmental and geographic factors to woody plant community structure. Aims We related alpha and beta diversity of woody plant communities to geographic distance and bioclimatic factors to understand the underlying factors of community structure. Methods We compared species composition among seven sites and calculated alpha (using effective numbers of species) and beta diversity using Whitaker and Bray–Curtis dissimilarity index. Canonical correspondence analysis (CCA) and a Mantel test were used to quantify how community structure was related to environmental and/or geographic distance. Results We found that Montes de María is as diverse as other dry forest fragments in Colombia. We detected three groups of communities which were shaped mainly by turnover associated with both precipitation and geographic distance. Conclusions The high beta diversity of the dry forest of Montes de María is related to a mixture of environmental variation and geographic distance.

地理距离和环境变化驱动哥伦比亚加勒比地区新热带季节性干旱林残片木本植物群落结构

摘要背景Montes de María是哥伦比亚加勒比海地区保存最完好的热带干林片断，是将环境和地理因素与木本植物群落结构联系起来的一个很好的模型。目的将木本植物群落的α和β多样性与地理距离和生物气候因素联系起来，以了解群落结构的潜在因素。方法我们比较了七个地点的物种组成，并使用Whitaker和Bray–Curtis相异性指数计算了α（使用有效物种数）和β多样性。使用典型对应分析（CCA）和Mantel检验来量化群落结构如何与环境和/或地理距离相关。结果我们发现Montes de María与哥伦比亚其他干旱森林碎片一样多样。我们检测到三组群落，它们主要由与降水量和地理距离相关的更替形成。结论Montes de María干燥森林的高β多样性与环境变化和地理距离的混合有关。

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.
