Tree-Ring Chronologies from Mozambique
Presented by Matthew THERRELL on 17 May 2013 from 08:30 to 08:50
Type: Oral Presentation
Session: Tropical Dendrochronology
Track: Tropical dendrochronology
We present results of recently conducted tree ring research on tropical tree species from Mozambique. We have developed new ring-width chronologies of two tropical hardwood species (Millettiia stuhlmannii, Panga panga and Vitex payos, Chocolate berry) from central Mozambique and use these chronologies to investigate the history of climate variability (principally seasonal drought) in the region. Initial analyses of the chronologies indicate that these species are strongly responsive to seasonal rainfall and should be useful for the development of long reconstructions of wet-season climate and linkages to large-scale ocean atmosphere forcing mechanisms. These species and other closely related species are widely distributed in Mozambique and adjacent areas in southern and eastern Africa, which suggests that a wider network of chronologies can be developed in this region.
