1. To study the systematics, distribution pattern, and use as a model of the interaction between ecological factors and evolutionary effect of the Southeast Asian macro-invertebrates fauna.
2. To determine the historical biogeographic pattern of Thai macro-invertebrate in comparisons with some taxon in nearby countries.
3. To produce a monograph, recording macro-invertebrate diversity occurring in Thailand and Southeast Asia and their utilizations in ago-ecosystem.
4. to establish an international standardized molecular nomenclature based upon DNA barcoding of Thai land molluscs, millipedes, centipedes and earthworms; to test the validity and the accuracy of the DNA barcoding method to use as the suitable tool of the selected taxonomic groups; and to construct the Thai barcode of life database for our region biodiversity management.
5. to assess the effect of a semi-aquatic earthworm Glyphidrilus quadratum Panha and Chanabun, 2012 and a terrestrial earthworm Metaphire posthuma (Vaillant, 1868) or Drawida sp. in associations, on soil aggregation and water infiltration rates, carbon sequestration, acidity and growth of upland rice (Oryza sativa). These relationships will be investigated in short scale experimental designs i.e. single or double cropping cycles (2-4 months per cycle).
