摘要

水生大型藻类是无脊椎动物的栖息地和直接食物来源，此外还间接提供藻类、碎屑和微生物。因此，水生大型藻类是栖息地的结构要素，需要区分栖息地的复杂性（物理形态，如分形尺寸、密度和生物量）和栖息地的异质性（这些结构的多样性）。在此，我们探讨了生境复杂性和生境异质性对无脊椎动物群落的影响。我们在巴西巴伊亚河（Baía River）13.7 公里河段的 28 个取样点收集了大型植物和无脊椎动物，并对特定种类（昆虫、微型甲壳动物和其他无脊椎动物）进行了研究。同时还测量了这些地点的环境变量。我们的目的是探索栖息地复杂性（以大型植物生物量衡量）和栖息地异质性（以大型植物功能多样性评估）对无脊椎动物丰富度和丰度的影响。我们发现，无脊椎动物的总体丰富度仅受生境异质性的积极影响。就无脊椎动物的丰度而言，中等复杂度的栖息地有更多的无脊椎动物，而栖息地的异质性则有积极影响。环境变量只影响丰度。就特定类群而言，昆虫的丰富度受生境异质性的积极影响，而昆虫的丰富度则随生境复杂度的升高而降低，随生境异质性的升高而升高。微型甲壳动物的丰度受生境复杂性的积极影响。其他无脊椎动物的丰富度和丰度受生境异质性的正向影响。无脊椎动物更喜欢中等复杂程度和高异质性的大型植被。丰度与结构复杂性和异质性有关，而物种丰富度与异质性的关系更为密切。此外，这些因素对不同无脊椎动物群的影响也各不相同。这些发现强调了在今后的研究中综合使用大型底栖生物生物量和功能多样性等多种指标来全面了解无脊椎动物群落动态的重要性。此外，我们的研究还表明，保护具有高度异质性的大型植物群落可显著提高相关无脊椎动物物种的多样性。

期刊介绍： Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
