Little, however, is known about the response of the region’s many lakes that support local biodiversity and supply water to downstream populations. We analyzed fossil diatom assemblages in dated sediment cores from three lakes with differing morphometry and catchment characteristics to document the limnological response to climate variability over the late Holocene. The study lakes contained similar dominant diatom taxa but recorded markedly different assemblage shifts over time. The two deeper lakes, Laguna Sibinacocha (zmax = 92 m) and Chaca Cocha (zmax = 18 m), contained diatom assemblages that oscillated in dominance between benthic fragilarioids (Staurosirella pinnata,enhttp://purl.org/coar/access_right/c_16eclimnología, Holoceno tardío, variabilidad climática, lagos andinoshttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/pe-repo/ocde/ford#1.05.07
