摘要墨角藻（Fucus serratus L.）在北方厄勒海峡的一个地点对其真菌进行了定量研究。共发现164种，并对不同的系统单位进行了区系和生态学处理。讨论了藻类生活动物的生态条件，特别是对墨角藻上的动物区系进行了讨论。结果表明，每平方米藻类表面的后生动物的数量相比，发现在一个水平底部社区。动物群的结构表明存在一个“墨角藻群落”。动物数量的波动记录了一年，最大的数量发生在夏末：25.000非固着动物在一个单一的植物。大多数物种在夏天繁殖，这解释了这个时候发生的巨大密度。最低密度在冬季和春季。数量减少主要是由于捕食。并对该动物群的食性进行了讨论。结果表明，非线性的主要部分是非线性的。
Abstract The metazoans on Fucus serratus L. and its epiphytes were studied quantitatively at a locality in the northern Oresund. A total of 164 species was found and the different systematic units treated faunistically and ecologically. The ecological conditions for algalliving animals are discussed, with special reference to the fauna living on Fucus serratus. It is shown that the number of metazoans per square metre algal surface compares with that found in a level-bottom community. The structure of the fauna indicates that a »Fucus serratus community« exists. The fluctuations in number of animals were recorded for one year, with the largest number occurring in late summer: 25.000 non-sessile animals on a single plant. Most species reproduced in the summer, which explains the great density occurring at this time. Lowest densities were found in winter and spring. The decrease in number was mainly due to predation. The feeding biology of the fauna is discussed. It is shown that the main part of the nonses...
