Escaping an evolutionary trap: preference and performance of a native insect on an exotic invasive host
- Margaret S. Keeler, F. Chew
- Biology, Medicine
- Oecologia
- 8 March 2008
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 very… Expand
COEVOLUTION OF PIERID BUTTERFLIES AND THEIR CRUCIFEROUS FOODPLANTS. II. THE DISTRIBUTION OF EGGS ON POTENTIAL FOODPLANTS
- F. Chew
- Biology, Medicine
- Evolution; international journal of organic…
- 1 September 1977
The extreme specificity of most phytophagous insects for their food resources is the hypothesized result of coevolution between insects and their foodplants (e.g. Ehrlich and Raven, 1965; Dethier,… Expand
Coevolution of pierid butterflies and their cruciferous foodplants
- F. Chew
- Biology, Medicine
- Oecologia
- 1 June 1975
SummaryTwo Colorado populations of Pieris butterflies show a spectrum of larval growth responses to potential foodplant crucifer species growing in montane habitats. Analysis of larval growth… Expand
Effects of urbanization on butterfly species richness, guild structure, and rarity

- 14 July 2007
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 from… Expand
Population structure of pierid butterflies

- Biology, Medicine
- Oecologia
- 1 March 1977
SummaryThe numbers, dispersal behavior, aging and residence, and Wrightian neighborhood configurations of three species of Colias butterflies have been studied in central Colorado, using… Expand
Coexistence and Local Extinction in Two Pierid Butterflies
- F. Chew
- Biology
- The American Naturalist
- 1 November 1981
Interactions of two sympatric, closely related Pieris species, indigenous P. oleracea and naturalized P. rapae, are described. The spatial and temporal distribution of adults and juveniles indicates… Expand
Modelling the impacts of two exotic invasive species on a native butterfly: top-down vs. bottom-up effects.
- Margaret S. Keeler, F. Chew, B. Goodale, J. M. Reed
- Biology, Medicine
- The Journal of animal ecology
- 1 May 2006
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 exotic… Expand
