Abstract

Abstract Caddisflies comprise a major component of the macroinvertebrate diversity of streams throughout the world. We studied temporal variation in the abundance and diversity of caddisflies of six streams in the monsoonal wet-dry tropics of northern Australia. Abundance and diversity of adult caddisflies were highly seasonal with most activity within wet season months from January to April, with a synchronous pulse of activity in the mid-dry season in two of the three years of study at some sites. Modelling of species richness showed variability among sites in the seasonal patterns of species richness. Multivariate analysis identified seasonal change in assemblage composition. These results are relevant to the design of biodiversity studies on seasonally flowing streams. Surveys of caddisfly diversity are most effectively undertaken during and after the wet season: repeated surveys are required to maximise the detection of the full suite of species occurring at a site.

澳大利亚北部达尔文地区溪边捕光法捕获的成年热蝇(毛翅目)的多样性和季节性

球虱是世界各地河流中大型无脊椎动物多样性的重要组成部分。我们研究了澳大利亚北部季风干湿热带地区6条河流中尸蝇的丰度和多样性的时间变化。成虫的丰度和多样性具有很强的季节性，主要活动在1 - 4月的湿季月份，在一些地点的3年研究中有2年在干季中期有同步的活动脉动。物种丰富度模型显示了不同站点间物种丰富度季节格局的差异性。多变量分析确定了组合成分的季节变化。这些结果对设计季节性流动河流的生物多样性研究具有一定的指导意义。在雨季期间和雨季之后，最有效地进行了对球虱多样性的调查:需要重复调查，以最大限度地发现在一个地点发生的全部物种。

期刊介绍： Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects. The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites). The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged. Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
