A field-based experiment was conducted on a detritus-loaded beach from the south coast of the British Isles (Poole Harbour) to investigate the decay rates of different combinations of algal detritus and their associated nematode assemblages. Ten algal mixture treatment combinations (monocultures with all possible 2 or 3 mixed algal treatments) of three different species of green (Chlorophyta), brown (Phaeophyta), and red (Rhodophyta) algae were used to determine how the diversity of decaying algal detritus affects the associated nematode assemblage composition and structure. Our results indicated that nematode density, diversity, and assemblage composition differed significantly among the different algal treatments. The nematode densities and genera richness were significantly higher in the mixed algal treatments compared to those in the algal monoculture treatments. The loss of seaweed dry weight varied significantly among the algal detritus treatments with which included brown algae tending to decay at a slower rate than others. These results indicate different type of macroalgae detritus could offer different nutrient input and that encourage different dominant nematode species and composition.

在不列颠群岛南海岸（普尔港）的碎屑堆积海滩上进行了实地实验，以研究不同藻类碎屑组合及其相关线虫组合的衰减率。三种不同种类的绿色（叶绿藻）、棕色（褐藻）和红色（红藻）藻类的 10 种藻类混合处理组合（单一培养和所有可能的 2 或 3 种混合藻类处理）用于确定腐烂藻类碎屑的多样性如何影响相关线虫组合的组成和结构。我们的结果表明，线虫密度、多样性和组合组成在不同藻类处理之间存在显着差异。与藻类单一栽培处理相比，混合藻类处理的线虫密度和属丰富度显着更高。海藻干重的损失在藻类碎屑处理之间差异很大，其中包括比其他藻类腐烂速度更慢的褐藻。这些结果表明不同类型的大型藻类碎屑可以提供不同的营养输入，并促进不同的优势线虫种类和组成。
