Former PhD student on a WOTRO project
titled:"Molluscan stable isotope growth-band
records of seasonality in modern and past Amazonian climates".
Through
the analysis of the stable isotope composition of modern and fossil mollusc
shells seasonal growth increments the aim of the Climazonia
project is: to assess the accuracy of modern molluscan shells as recorders
of seasonal environmental change in Amazonia. The stable isotope composition
of the shells of living molluscs monthly collected in a one year field
experiment, will be compared to host water samples, and to climatic records
(rainfall, water- and air temperature).
Using
the results of this experiment, we will then reconstruct past Amazonian
aquatic environments and seasonality through the analyses of fossil molluscs.
A key target for the reconstructions will be the stability of the climatic
conditions during Miocene uplift phases of the Andes mountain range.
