Escaping an evolutionary trap: preference and performance of a native insect on an exotic invasive host
Exotic plants may act as population sinks or evolutionary traps for native herbivores. The native butterfly Pieris oleracea lays eggs on garlic mustard, Alliaria petiolata, but larvae develop veryExpand

Effects of urbanization on butterfly species richness, guild structure, and rarity
We evaluated the effects of landscape characteristics associated with urbanization, as well as local features, on butterfly species richness at four spatial scales (50, 150, 500, and 1,000 m fromExpand

Modelling the impacts of two exotic invasive species on a native butterfly: top-down vs. bottom-up effects.
1. Exotic invasive species can influence population dynamics of native species through top-down or bottom-up forces. The present study examined separate and interactive effects of multiple exoticExpand
