Table 2 Total number of reads from metagenomic sequencing which were filtered to remove low quality reads. The mean (SD) represent the mean number of reads for each oil palm landscape types (MCP, FPP and NFP). Four measures of alpha diversity (Shannon, Simpson, Chao 1 and Observed) are shown to compare genetic diversity within insect communities in different landscapes.

From: DNA metabarcoding confirms Copsychus saularis, the common insectivorous species in oil palm plantations as biological control of ground-dwelling insect pests
