Increased relative abundance of colonial scaled chrysophytes since pre-industrial times in minimally disturbed lakes from the Experimental Lakes Area, Ontario

In this paper, a top–bottom paleolimnological analysis of 30 undisturbed lakes in the Experimental Lakes Area (ELA) in northwest Ontario showed marked increases in the relative abundance of colonial scaled chrysophyte taxa in most lakes since pre-industrial times. The increase in abundance of colonial taxa was primarily driven by Synura sphagnicola in small, high-nutrient, and warm lakes. The colonial taxa Synura petersenii and Synura echinulata also increased in the deeper study lakes.

Sediment cores comprised of sediments deposited during the last 40-100 years were retrieved from two reservoirs in the recently populated Dry Zone of Sri Lanka. Observed increases in pelagic Cladocera in both reservoirs, suggest increases in both water level and nutrients which are consistent with the timing of watershed modifications that would promote higher water levels and nutrients.
