Primary Production and Species Richness in Lake Communities 1997 - 2000

An understanding of the relationship between species richness and productivity is
crucial to understanding biodiversity in lakes. We investigated the relationship between the
primary productivity of lake ecosystems and the number of species for lacustrine
phytoplankton, rotifers, cladocerans, copepods, macrophytes, and fish. Our study includes
two parts: (1) a survey of 33 well-studied lakes for which data on six major taxonomic
groups were available; and (2) a comparison of the effects of short- and long-term
whole-lake nutrient addition on primary productivity and planktonic species richness Dodson,
Stanley I., Shelley E. Arnott, and Kathryn L. Cottingham. 2000. The relationship in lake
communities between primary productivity and species richness. Ecology 81:2662-79. Number of

厘清物种丰富度与生产力之间的关联，对于理解湖泊生物多样性至关重要。本研究针对湖泊生态系统初级生产力与六大类群——湖泊浮游植物、轮虫、枝角类、桡足类、大型水生植物及鱼类——的物种数量之间的关系展开探讨。本研究包含两部分内容：（1）对33个经充分研究的湖泊开展调查，上述湖泊均具备六大类群的完整观测数据；（2）对比短期与长期全湖营养盐添加实验对初级生产力及浮游类群物种丰富度的影响。本研究数据源自：Dodson, Stanley I., Shelley E. Arnott, 及 Kathryn L. Cottingham. 2000. 《湖泊群落初级生产力与物种丰富度的关联》. Ecology 81:2662-79. 调查位点总数：33个
