The paper shows that negative feedback from limited male mating success stabilizes costly female preferences and displays, resolving evolutionary puzzles about their persistence.

This study shows that selection against hybridization increases reproductive isolation between Drosophila populations while allowing gene flow, with intermediate selection producing the strongest isolation.

This study examines the colonization and diversification of Xylocopa darwini across Galapagos islands, finding long-term isolation, divergence between eastern and western islands, and recent founder events.

The paper analyzes mitochondrial variation in the DGRP, identifies haplotype-specific phenotypic associations, and finds no major fitness effects from mito-nuclear incompatibilities.
