摘要

这项研究强调了环境过滤器在浮游动物群落动态以及与热带潮间带河口三个区域浮游植物生态关系中的重要性。因此，在普雷吉萨斯河河口战略位置的六个不同地点进行了取样，目的如下：确定浮游动物的丰度特征，并由此确定群落的 α 和 β 多样性指数随环境变量的变化；确定影响生态系统区域指示物种的环境过滤器；确定浮游植物和浮游动物在河口梯度上的相互作用。浮游动物群落包含 80 个物种，包括 14 个门类，其中节肢动物门种类最多，其次是纤毛虫门和软体动物门。桡足类尤为突出，其中主要有 Paracalanus crassirostris、Pseudodiaptomus gracilis 和 Oithona nana。共有 21 个物种被选为指标，其中包括沿海地区的湍流栉水母（Temora turbinata）、混合区的褶皱栉水母（Rhizodomus tagatzi）和潮汐河流区的微型栉水母（Moina micrura）。环境异质性显示出明显的空间差异，其变化主要受盐度、温度和悬浮有机物的影响，它们是主要的环境过滤器。沿岸带和混合带的物种与硅藻 Skeletonema costatum 和 Asterionellopsis glacialis 的藻华有直接的生态关系，它们的出现有利于浮游动物的丰度，表明营养网络受自上而下的控制。在 β 多样性的分区中，由于环境异质性，周转成分对多样性值负责，从而区分了不同区域的群落。我们的研究结果是对这一热带生态系统中环境异质性与浮游动物之间关系的首次全面调查。这些发现对于确定极易退化的环境（β 多样性低）和作为扩散中心的环境（β 多样性高）至关重要，从而有助于开展有针对性的保护工作和更有效地管理河口系统。因此，我们的研究结果为世界各地类似沿海生态系统的可持续管理提供了重要依据。

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.
