Abstract

In the published article, the upper panel of Figure 6 was erroneously based on an earlier version of the age model. The updated figure, including the final and corrected age model, is printed below: [Figure presented] Fig. 6. Ecohydrological history of Lake Naivasha during the past 1650 years. Overview of ostracod-based reconstructions (CeF) in relation to the fluctuations in lake depth and salinity derived from other proxies (AeB). Yellow-shaded areas highlight the episodes when CIC was hydrologically closed; red vertical lines are the ostracod zonation boundaries, as in Fig. 4 (A) Lake-level reconstruction, revised from Verschuren (2001). Water depth at the deepest point of the CIC basin is plotted in relation to the estimated minimum elevation halting sediment focusing into CIC (dashed line 1); the sill elevation between CIC and the main basin of Lake Naivasha (dashed line 2); and the estimated maximum elevation for hydrological closure of CIC (dashed line 3); all three dashed lines are slanted, to reflect the overall reduction in water depth over time due to sediment infill. (B) Reconstruction of diatom-inferred conductivity, as in Verschuren et al. (2000a) but extended beyond 770 CE to the base of the record. (C) PCA scores summarizing the stratigraphic turnover in fossil ostracod assemblages. (D) Additional ostracod proxy information: i) depth interval with highest taxon richness (asterisk; cf. Fig. 4), indicating the onset of more permanent Malewa River inflow; ii) depth intervals with elevated proportion of non-calcified Z. costata valves (stippled line), reflecting reduced lake-water alkalinity and residence time; and iii) intervals containing large (>1000 mm) ostracod species (grey line sections), reflecting limited fish predation. (EeF) LOESS-smoothed time series of ostracod d18O and d13C, vertical bars represent the range in measured data at a given depth. All panels are plotted on a linear time axis according to the updated age model, with a non-linear depth axis for reference.
