Currently our research focuses on the dynamic responses of
plants to environmental heterogeneity. We know a lot about how
plants respond to specific environmental factors but we know
little about how they respond to spatial and temporal variation
in these factors or how these effects are integrated at the
whole plant level. We combine physiological, chemical and
isotope (stable and radio) techniques to elucidate patterns and
identify mechanisms.
Projects in the lab include:
- how herbivory affects the allocation of resources to
chemical defenses and nutrient uptake/storage, and how this
affects subsequent plant resistance
- how the vascular architecture of plants constrains their
responses to patchy nutrient availability, and
- ecological and evolutionary trade-offs in plant form and
function as it relates to long-distance transport of
resources.
Prior research projects include:
- the role of salt spray on plant community structure in
Martha's Vineyard,
- the effects of genotype by environment interactions on
plant traits and resistance to herbivores, and
- the consequences of hybridization among plants to
plant-herbivore interactions.
