Seasonal and depth distribution of LD12 abundances (white bars) in relation to water temperature (gray area) in temperate lakes. (a) Seasonal development of LD12 bacteria in Piburger See, Austria, in 3 m depth and corresponding abundances of LD12 bacteria with active amino acid uptake (gray bars). (b) Mean values and s.d. (n=3) in Thalwiler Waldweiher, Switzerland, in 0–2 m depth. (c) Depth distribution in Piburger See in July 2005 and corresponding abundances of LD12 bacteria with active amino acid uptake. (d) Depth distribution in Thalwiler Waldweiher in June 2008, (e) in Lake Constance, Germany, in July 2009 and (f) in Egelsee, Switzerland, in September 2007. nd, amino acid uptake assay not conducted.
