Genomic evidence that resource-based trade-offs limit host-range expansion in a seed beetle by Gompert, Zachariah, Messina, Frank J.

“…Trade-offs have often been invoked to explain the evolution of ecological specialization. Phytophagous insects have been especially well studied, but there has…”

Evolution of host acceptance and its reversibility in a seed beetle by MESSINA, FRANK J., GOMPERT, ZACHARIAH

“…1. Adapting to a low‐quality plant may require modification of an insect's digestive physiology, oviposition behaviour, or other host‐use traits. If colonising…”
