The paper shows that fitness effects of genetic differences in photoperiodism for diapause timing depend on egg-laying timing in a butterfly, with southern populations performing better when laying eggs early.

upSPLAT reduces library preparation costs by 10-fold through early barcoding and single-stranded ligation, enabling cost-effective, high-plex sequencing across diverse DNA inputs.

This paper reviews literature and analyzes studies showing photoperiodism for diapause induction evolves predictably with latitude, while clinal variation in life history and thermal plasticity is inconsistent across taxa.
