I study direct and indirect effects of behavioral and species
interactions on population-level phenomena: When do interactions between
species have fitness consequences for individuals, and when do these
fitness effects influence population dynamics? I am also interested in
the ways human-induced changes, such as habitat fragmentation and
introduced species, affect the behavior and population dynamics of
species involved in multi-species interactions (including mutualisms).
In my research, I address these issues using a combination of field and
lab experiments, statistical and mathematical models, and molecular
tools. In addition, I focus primarily on interactions involving fungi,
and more recently viruses, which touch on the rapidly growing but still
relatively poorly developed fields of microbial and virus ecology. I
have studied plant-associated fungi and fungal viruses; indirect
interactions involving plants that share pollinators, or between plants,
plant-associated fungi and insect vectors; multi-trophic interactions
between plants; and mutualisms between plants and pollinators. Thus, I
study animal vectors of pollen or fungal pathogens, and their individual
and population-level effects on fungi and plants. My work addresses
three main questions. (1) What factors might enable plant-pollinator
mutualisms to persist when plants are at low densities? (2) What are the
behavioral, fitness, and population consequences of competitors on
mutualisms involving plant pathogens and their vectors? (3) What role do
plant-associated fungal viruses play in ecological communities?
