Lepidopteran larvae possess multiple defenses against a diverse group of predators and parasitoids. Many studies of larval defenses have determined whether a defense works against a particular enemy,Expand

Host specificity of Lepidoptera in tropical and temperate forests
For numerous taxa, species richness is much higher in tropical than in temperate zone habitats. A major challenge in community ecology and evolutionary biogeography is to reveal the mechanismsExpand

The global distribution of diet breadth in insect herbivores
Significance Dietary specialization determines an organism’s resource base as well as impacts on host or prey species. There are important basic and applied reasons to ask why some animals haveExpand

Revisiting the evolution of ecological specialization, with emphasis on insect-plant interactions.
Ecological specialization is a fundamental and well-studied concept, yet its great reach and complexity limit current understanding in important ways. More than 20 years after the publication of D.Expand

Climatic unpredictability and parasitism of caterpillars: implications of global warming.
Insect outbreaks are expected to increase in frequency and intensity with projected changes in global climate through direct effects of climate change on insect populations and through disruption ofExpand

Immunological cost of chemical defence and the evolution of herbivore diet breadth.
Selective pressures from host plant chemistry and natural enemies may contribute independently to driving insect herbivores towards narrow diet breadths. We used the specialist caterpillar, JunoniaExpand

Right from the Start: Exploring the Effects of Early Team Events on Subsequent Project Team Development and Performance
This study examines if high- and low-performing project teams differ with respect to how they are mobilized and launched and the effects of their mobilization and launch activities and outputs onExpand

Phytochemical diversity drives plant–insect community diversity
Significance Phytochemical diversity is a key component of functional diversity. Challenges in quantifying phytochemical diversity have limited our understanding of the causes and consequences ofExpand

Tasty Generalists and Nasty Specialists? Antipredator Mechanisms in Tropical Lepidopteran Larvae
To examine the effectiveness of larval antipredator mechanisms and to test the assumption that diet breadth and chemistry are important predictors of predation responses. I offered 70 species ofExpand
