1981年7月,作为生产研究的一部分,开始对Loosdrecht湖的浮游生物进行研究(另见BEST等人,1984年; DE Kr. OET等人,1984年; KROMKAMP和GoNs,1984年)和磷动力学(BoERS等人,1984年)。在本论文中,浮游动物的结构,现在比较,在19 SS的一年,每两周的数据在Loosdrecht湖之一的浮游动物密度和生物量收集的J. FM GEELEN博士(unpubl。数据);其次,根据这些湖泊和荷兰其他湖泊的营养状况,研究了甲壳类滤食性动物的放牧活动(GuLATI等人,1982年)。此外,目前的数据形成了一个基线清单,用于与湖泊恢复可能发生的变化进行比较,这项工作计划于1984年初开始(货车LIERE等人,1984年)。
The woplankton study in the Loosdrecht Lakes was started in July 1981 as a part of research on production (see also BEsT et al. 1984; DE Kr. OET et al. 1984; KROMKAMP & GoNs 1984) and phosphorus dynamics (BoERS et al. 1984). In the present paper the zooplankton structure now is compared with that in 19SS for which year fortnightly data on zooplankton densities and biovolumes in one of the Loosdrecht Lakes were collected by Dr. J. FM GEELEN (unpubl. data); secondly, the grazing activities of the crustacean filterfeeders are examined in the light of trophic status of these lakes and other Dutch lakes (GuLATI et al. 1982). Besides, the present data form a base line inventory for comparing with changes likely to occur on lake restoration, work on which is planned to be commenced in early 1984 (vAN LIERE et al. 1984).
