Table A.3
Assigned taxa into functional groups. Total numbers of specimens sampled using blow vac (BV) and sweep net (SN) in both study regions (Hai Duong and Vinh Phuc). Not all specimens were identified to the lowest taxon shown here and therefore some orders were listed with specimens even if there are families or species within this group identified and listed.

Each model is separated by blow vac (BV) and sweep net (SN) as well as sampling days (35 and 50 days after transplanting). Global models show the estimate, standard error (SE), t-value and p-value of the intercept and predictor variables for each model.

Figure A.1
Non-significant relationship between functional group diversity (a-c) and taxonomic diversity (d-f) with land cover heterogeneity for blow vac (BV) and for sweep net data (SN) at 35 and 50 days after transplanting. Alpha diversity is based on the exponential Shannon entropy and expressed as effective numbers of functional groups. Pesticides were measured as number of pesticide applications. Land cover heterogeneity is based on Shannon index (H’).
