Species specificity and intraspecific variation in the chemical profiles of <i>Heliconius</i> butterflies across a large geographic range.

Project description:In many animals, mate choice is important for the maintenance of reproductive isolation between species. Traits important for mate choice and behavioral isolation are predicted to be under strong stabilizing selection within species; however, such traits can also exhibit variation at the population level driven by neutral and adaptive evolutionary processes. Here, we describe patterns of divergence among androconial and genital chemical profiles at inter- and intraspecific levels in mimetic Heliconius butterflies. Most variation in chemical bouquets was found between species, but there were also quantitative differences at the population level. We found a strong correlation between interspecific chemical and genetic divergence, but this correlation varied in intraspecific comparisons. We identified "indicator" compounds characteristic of particular species that included compounds already known to elicit a behavioral response, suggesting an approach for identification of candidate compounds for future behavioral studies in novel systems. Overall, the strong signal of species identity suggests a role for these compounds in species recognition, but with additional potentially neutral variation at the population level.

The genetic basis of structural colour variation in mimetic Heliconius butterflies [erato]

Project description:We use RNAseq data to perform differential gene expression to identify genes controlling structural colouration in two co-mimetic species of Heliconius butterfly - Heliconius erato and Heliconius melpomene. We use comparisons between iridescent and non-iridescent subspecies of Helcionius erato (H. e. cyrbia and H. e. demophoon, respectively) and Helcionius melpomene (H. m. cythera and H. m. rosina, respectively) at two separate developmental stages, 50% and 70% of development. In addition, in the iridescent subspecies of both H. erato and H. melpomene, we compared the iridescent wing regions (forewing and hindwing combined) to the non-iridescent androconial wing region using differential gene expression.

The genetic basis of structural colour variation in mimetic Heliconius butterflies [melpomene]

Project description:We use RNAseq data to perform differential gene expression analysis to identify genes controlling structural colouration in two co-mimetic species of Heliconius butterfly - Heliconius erato and Heliconius melpomene. We use comparisons between iridescent and non-iridescent subspecies of Helcionius erato (H. e. cyrbia and H. e. demophoon, respectively) and Helcionius melpomene (H. m. cythera and H. m. rosina, respectively) at two separate developmental stages, 50% and 70% of development. In addition, in the iridescent subspecies of both H. erato and H. melpomene, we compared the iridescent wing regions (forewing and hindwing combined) to the non-iridescent androconial wing (anterior hindwing) region using differential gene expression.

Tiling microarray expression analysis of Heliconius butterfly pupal forewing sections across the genomic interval controlling red color pattern

Project description:We investigated gene expression levels in Heliconius erato butterflies with divergent wing patterns across a 656KB genomic interval linked to the red color pattern wing polymorphism. This included comparison of expression between two H. erato color pattern populations (H. e. petiverana and a H.e. etylus x H. himera hybrid) across three sections of the forewing that differed in pigmentation (the basal, mid, and distal wing sections) and five different stages of pupal development (Day 1, 3, 5 pupae and ommochrome and melanin pigmentation stages). These results allowed us to determine whether certain genes in this interval were differentially expressed between the wing pattern elements, and, therefore, potentially responsible for adaptive color pattern variation in these butterflies.

RNA-seq of adult Heliconius melpomene rosina male and female chemosensory tissues: antennae, labial palps and proboscis, and legs

Project description:The purpose of this experiment was to compare RNA-seq profiles of adult male and female butterfly chemosensory tissues to identify tissue- and sex-specific differences in gustatory and olfactory gene expression. Three biological replicates per sex were produced from individual Heliconius melpomene rosina butterflies. For the antennal libraries, both antennae were used, for the labial palps + proboscis libraries both labial palps and each proboscis was used, and for the leg libraries all six legs were used.

Genome-wide regulatory adaptation shapes population-level genomic landscapes in Heliconius [RNA-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.
