Genomic variation and adaptation in fragmented landscapes

ABSTRACT: We have compared allelic and gene expression variation using individual-based RNA-seq data from four regional populations of the Glanville fritillary butterfly (Melitaea cinxia) in northern Europe. Two of the populations represent fragmented habitat and two continuous habitat. Based on sequence information, we constructed genealogy for four populations. Based on gene expression, we found 1841 genes to be differentially expressed between two different landscape types. Our results demonstrate genomic adaptations to living in fragmented landscapes, which are likely to be related to phenotypic life-history adaptations that have been documented for many species.

Dispersal, flight metabolism and gene expression in the Glanville fritillary butterfly

Project description:We have measured flight effect in gene expression using individual-based RNA-seq data from two regional populations of the Glanville fritillary butterfly (Melitaea cinxia). Largest number of differentially expressed genes were between populations (3840 genes) and between males and females (1622 genes). 801 genes had significant flight effect. Enriched GO and KEGG categories among these genes included hypoxia, glycolysis, and TCA cycle.

Genome-wide regulatory adaptation shapes population-level genomic landscapes in Heliconius [ATAC-seq]

Project description:We test the hypothesis that intraspecific genomic divergence is linked to regulatory variation between Heliconius butterfly populations. We show that population-level divergence in chromatin accessibility and regulatory activity during wing development is abundant, and that differences in regulatory activity between populations are strongly associated with developmental stage. Genomic regions with high Fst are highly enriched for regulatory variants, and enrichment patterns vary significantly across development. Regulatory variants are associated with most differential gene expression between populations, and our data point to two roles for histone modifications in the evolution of gene expression.
