Pervasive fitness trade-offs revealed by rapid adaptation in large experimental populations of Drosophila melanogaster

Mark C. Bitter, Sharon I. Greenblum, S. Rajpurohit, Alan O. Bergland, James A. Hemker, Egor Lappo, Nicolas J. Betancourt, Susanne Tilk, Skyler Berardi, Hayes Oken, P. Schmidt, Dmitri A. Petrov

This study uses genomic data from Drosophila melanogaster to show how fitness trade-offs manifest under fluctuating selection, identifying genomic regions linked to reproduction and stress tolerance.

Drosophila melanogaster pigmentation demonstrates adaptive phenotypic parallelism over multiple timescales

Skyler Berardi, Jessica A. Rhodes, M. C. Berner, Sharon I. Greenblum, Mark C. Bitter, Emily L. Behrman, Nicolas J. Betancourt, Alan O. Bergland, Dmitri A. Petrov, Subhash Rajpurohit, PAUL S. SCHMIDT

This study shows that Drosophila melanogaster pigmentation adapts rapidly and deterministically to environmental gradients across multiple timescales through distinct genetic components.
