I am interested in the causes and consequences of variability in biological
communities. My research focuses on patterns of variation in giant
kelp (Macrocystis pyrifera) forests at multiple spatial and temporal scales
throughout the species’ geographic range in the Northeast Pacific Ocean.
As part of my research program, I have been examining the relative importance
of numerous physical and biological factors in the structuring of kelp
forest communities, as well as how these factors modify interactions among
co-occurring species, with particular emphasis on large-scale phenomena
(such as El Niño Southern Oscillations and global climate change).
A second focus of my research program has been to examine how opportunistic
marine algae maintain populations in spatially and temporally heterogeneous
environments, with particular attention on the role of dormant microscopic
life-history stages. My future research plans involve continuing
to assess the causes and consequences of variation in kelp forests while
attempting to assess how different life-history traits allow some species
to either take advantage of or buffer against variation in environmental
conditions. By examining these processes at multiple scales over
large geographic areas and long time periods, I hope my research will ultimately
offer insights into the issue of generality, an often contentious but poorly
understood issue in ecology.
