Abstract

Changes in the macrozoobenthos of two northern lakes differing in degree of humification of water over the 50-year period that have passed since the first studies were considered. In the lake with water uncolored by humus, the benthos biomass increased, and in the humified one, it decreased. The changes that have occurred are due to climate warming, especially pronounced in winter. It was concluded that even closely located bodies of water can respond differently to climate change. Depending on the nature of the catchment area and the morphology of the lakes, either an increase in their productivity due to the supply of nutrients or a decrease due to humification can be observed.

作为气候变化指标的亚北极湖泊大型底栖生物
摘要 研究了自首次研究以来的 50 年间,北方两个湖水腐殖化程度不同的湖泊中大型底栖生物的变化情况。在水体未被腐殖质染色的湖泊中,底栖生物的生物量有所增加,而在被腐殖质染色的湖泊中,底栖生物的生物量则有所减少。发生这种变化的原因是气候变暖,尤其是在冬季。得出的结论是,即使是距离很近的水体也会对气候变化做出不同的反应。根据集水区的性质和湖泊的形态,可以观察到湖泊的生产力因营养物质的供应而提高,或因腐殖化而降低。
