basis: stronger zonal atmospheric circulation during the early Holocene remains the most plausable mechanism to explain the strong shifts in the d18O-MAT relation. Temperature equation applied to surface sediment yields essentially modern July temperatures|lake water d18O corresponds with pollen-inferred temperatures.

basis: the water body is affected by a well-developed evaporative isotopic enrichment in spite ofthe rather short residence time (ca 20 days or less) as estimated from catchment size and meteorological data. Surface run-off from the catchment and direct precipitation seems to have no major impact on the isotopic composition oflake water during the ice-free season; groundwater level and related adjustments of lake level and surface/volume ratio of the basin during the ice-free season

basis: Trace element (Mg and Sr) concentrations in ostracod shells from Lakes Salpete ?n and Pete ?n Itza ? parallel the ?18O records, suggesting that ?18O records ref ect basin hydrology rather than changes in the isotopic composition of rainfall (Rosenmeier et al., in press). Furthermore, covariance in both ?18O and Mg eliminate temperature as a control on the oxygen isotope record.
