摘要

水生昆虫是湿地生态功能的关键，水陆两栖昆虫（如蜻蜓）的分布共同取决于水生和陆生环境条件。因此，厘清湿地内部和景观构成的相对影响有助于预测鸟纲昆虫对湿地环境变化的反应。利用巴西南部潘帕地区（南里奥格兰德州中西部）19 块湿地的数据，我们评估了水化学和土地覆盖变量对尾翅目幼虫群（鞘翅目和颧翅目亚目）的丰富度和组成的相对重要性。鞘翅目丰富度随 pH 值和裸露土壤面积的增加而降低。水的 pH 值和裸露土壤面积、农业用地的镶嵌以及水体土地覆盖是影响蜻蜓和鞘翅目昆虫组成的主要因素。我们的研究结果表明，尽管土地转换和水质相关机制的复杂相互作用驱动着巴西潘帕淡水湿地中的鸟纲幼虫的分布，但土地覆盖是鸟纲幼虫群落结构的主要驱动因素。我们的研究结果的主要意义在于，土地覆盖的改变是潘帕湿地中蜻蜓分布的主要威胁，并可能对这些生态系统的营养结构和功能产生影响。

Land cover is the main driver of the distribution patterns of larval Odonata assemblages in freshwater wetlands of the Brazilian Pampa

Aquatic insects are key to wetland ecological functioning, and the distribution of amphibious insects such as Odonata jointly depends on environmental conditions in the aquatic and terrestrial settings. Therefore, untangling the relative effects of within‐wetland and landscape composition can help predict the responses of Odonata to environmental alterations in wetlands. Using data from 19 wetlands spanning over the southern Brazilian Pampa (center‐western Rio Grande do Sul state), we assessed the relative importance of water chemistry and land‐cover variables to the richness and composition of larval Odonata assemblages (and suborders Anisoptera and Zygoptera). Anisoptera richness decreased with pH and bare soil area. Water pH and areas of bare soil, mosaic of agricultural land use, and waterbodies land cover were the main drivers of Odonata and Zygoptera composition. Our results indicate that land cover is the main driver of the assemblage structure of larval Odonata, although a complex interplay of mechanisms associated with land conversion and water quality drive the distribution of larval Odonata in freshwater wetlands of the Brazilian Pampa. The major implication of our findings is that land cover modification is the major threat to Odonata distribution in Pampean wetlands, with potential impacts on the trophic structure and functioning of these ecosystems.

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.
