To discern representative samples is helpful for understanding the soil-landscape relationships in an area and the proposed method can be used to design supplementary samples for a better soil mapping result.
For the supplementary sample, 228 return migrants in Mannar district were identified and approached, all of whom agreed to participate, resulting in a combined sample of 242 return migrants with a mean (SE) age of 40.4 (0.85) years.
For the supplementary sample, the same inclusion criteria were applied as in the baseline sample (Sri Lankan nationality, aged 18 65, originally resident in the Northern Province of Sri Lanka, displaced in 1990 and subsequently residing in welfare camps and other settlements in Kalpitiya division of Puttalam district, or born to at least one displaced parent with these characteristics).
For these reasons, many of the baseline study population had opted to remain in displacement, or had not yet been drafted in to the process of return migration by the government – hence the need for a supplementary sample of return migrants at follow-up.
Furthermore, there is no change in CPF eligibility status within the period of our study for both our main and supplementary samples.
The average coverage of mitochondrial consensus sequences was higher than 74× for all samples (supplementary table S2, Supplementary Material online).
The D. melanogaster data have lower temporal resolution, but show similar trends, both for values averaged between different samples representing the same developmental interval (fig. 2 a, right), and for individual samples (supplementary fig. S1, Supplementary Material online).
Given that no incongruence was found between the FISH-determined orientation and the haplotype sequence (fig. 1), a set of previously described inversion-markers (Antonacci et al. 2009; Donnelly et al. 2010) were used to infer the inversion status for all individual samples (supplementary table S2, Supplementary Material online).
We extracted 53 common chloroplast protein-coding genes (supplementary table S1, Supplementary Material online) for 60 sampled taxa (supplementary table S2, Supplementary Material online) from the NCBI organelle database.
Other market failures call for supplementary policies.
ASCAT results were confirmed by genotyping rs680 using pyrosequencing, which confirmed loss of heterozygosity for 8/8 informative samples (Supplementary Table 2, see section on supplementary data given at the end of this article).
