Darwin project quantifies the impact of hydroperiod on aquatic biodiversity in the Okavango Delta

Anson Mackay, Tom Davidson and Richard Mazebedi presented results from their Darwin-funded project on the Okavango Delta at a final project meeting on Wednesday 15th April, in Maun, Botswana.

Several hydrological and chemical variables, including hydroperiod, were shown to be significant in determining the diversity of three important groups of aquatic organisms in the Delta: diatoms, aquatic macrophytes and macroinvertebrates. Co-principal investigator Dr Piotr Wolski from the Harry Oppenheimer Okavango Research Centre presented model results on regional hydrology and climate variability. Dr Martin Todd also participated in the workshop, and led  a course on Climate Variability, which was well attended by several governmental departments and stakeholders involved in biodiversity research on the Delta.
