Research
Interests
I study how ecological communities assemble and its implications
for species diversity, ecosystem functioning, biological invasions,
and ecological restoration, both at ecological and evolutionary
time scales. I use a variety of study systems and methods in
collaboration with other biologists to address questions most
effectively.
1. Species diversity: Species diversity often shows non-random
patterns in relation to ecosystem productivity, ecosystem
size, ecosystem connectivity, the size of the regional
species pool,
and other ecological variables. I have found that these patterns
can depend on the history of community assembly, or more
specifically, on the sequence and timing in which species
attempt to join
communities. For this work, I have used theoretical computer
simulations and microbial microcosm experiments.
2. Ecosystem functioning: I am currently studying the ecosystem-level
consequences of community assembly. How do historically
derived differences in community structure affect the way
ecosystems
function? My main focus for this work has so far been wood-decay
fungi as a model system. My collaborators and I are doing
field and laboratory experiments in New Zealand to ask
how top-down
and bottom-up forces interact with community assembly history
to affect fungal communities and how these interactions
in turn influence nutrient cycling in forests.
3. Evolutionary diversification: I am interested in incorporating
evolutionary diversification into community-assembly
theory, which has largely been limited to ecological, as
opposed
to evolutionary, dynamics. For this, I am using the bacterium
Pseudomonas fluorescens, which undergoes adaptive radiation
in just a week in microcosms. In addition, Matt Knope,
who recently started working with me, and I are currently
setting
up our lab for molecular phylogenetic approaches.
4. Other interests: I have also worked on sequence effects
of disturbance on community structure, implications of community
similarity for ecosystem functioning, and species divergence
vs. trait convergence in community assembly. Other projects
I have been involved in include across-ecosystem trophic
cascades on New Zealand islands and plant-pollinator interactions
on
Hawaiian islands.
