The composition of animal communities developing from planktonic larvae in aquariums. A marked increase in the abundance of the annelid Polydora ligni in aquariums containing sand and flowing estuarine water was altered in the presence of the carbamate insecticide Sevin (carbaryl). Treatments were control and concentrations of Sevin that averaged 1.1, 11.1, and 103 micrograms/l; each treatment was replicated 8 times. Animals that colonized aquarium sand were collected in a 1-mm mesh sieve after 10 wk of exposure. Mollusks' arthropods, annelids, and nemerteans were the numerically dominant phyla. The average number of species per aquarium was significantly less (alpha = 0.05) in aquariums containing 11.1 or 103 micrograms/l than in those containing 1.1 micrograms/l or in control aquariums. The abundant clam Ensis minor grew significantly less in length at the higher concentrations of Sevin. The amphipod Corophium acherusicum was particularly affected; significantly fewer were found at all concentrations than in the control aquariums containing 103 micrograms/l corresponded to a marked decrease in the number of other annelids and to a significant absence of nemerteans.
水族箱中由浮游幼虫发育而来的动物群落组成。在含有沙子和流动河口海水的水族箱中，环节动物多毛海蚯蚓数量显著增加，但在氨基甲酸酯类杀虫剂西维因（甲萘威）存在的情况下，这种情况发生了改变。处理方式包括对照以及西维因浓度平均为1.1、11.1和103微克/升的处理组；每个处理组重复8次。暴露10周后，用1毫米筛网收集在水族箱沙子上定殖的动物。软体动物、节肢动物、环节动物和纽形动物是数量上占主导的门类。与含有1.1微克/升的水族箱或对照水族箱相比，含有11.1或103微克/升的水族箱中每个水族箱的平均物种数量显著减少（α = 0.05）。在较高浓度的西维因环境下，数量众多的小荚蛏长度生长显著减缓。双足虾类的阿氏角镖水蚤受到的影响尤为明显；在所有浓度下发现的数量都显著少于对照水族箱，含有103微克/升的情况下，其他环节动物数量明显减少，纽形动物则显著缺失。
