Research Specialization


My research focuses on investigating species interactions and their effects on trophic dynamics and ecosystem services within the contexts of invasion biology, community ecology and evolutionary ecology. Biological invasions alter ecosystems and their functioning, but predicting these effects has proven difficult. Both invaders and native taxa can undergo micro-evolutionary changes or display phenotypic plasticity following a biological introduction. The degree and form of this plasticity can affect invaders’ evolutionary and ecological success. Typically, adaptations relevant to invasion success are attributed to either recent evolutionary responses to novel selection pressures (in introduced ranges) or long-term adaptations to local conditions (in native ranges). Thus, native-introduced range comparisons shed light on how and when invader traits evolve. Integrating quantitative, stable isotope and molecular approaches, my work evaluates these interactions by quantifying invader impacts in the field, identifying the mechanisms underlying these interactions, evaluating their contributions to ecosystem services and determining traits that facilitate invasion. Specific areas of current research involve life history evolution of invasive species, invasive generalist predators and trophic impacts of multi-channel omnivory.
