P values of t test compared the mean values of the P_D, the number of synonymous SNVs at transcripts with heterozygous loci (the counts per kb), the proportion of non-synonymous SNVs to total SNVs on transcripts with heterozygous loci, the proportion of nonsense SNVs to total non-synonymous SNVs on transcripts with heterozygous loci, and proportion of deleterious variations in non-synonymous SNVs on transcripts with heterozygous loci estimated by PROVEAN and SIFT between endangered island endemic [EIE] and non-endangered [NE] species
