My research interests focus on how ecological and evolutionary processes, and their interactions, may affect responses to environmental change in plants. I use a combination of observational and experimental ecological data, genetic markers, and statistical modeling to address a variety of questions about plant population ecology. My long-term goal is to understand how dispersal, patterns of genetic diversity, and life history interact to influence the vulnerability or resilience of species to global environmental change.
projects currently under development will address how dispersal, local
adaptation, and disturbance rate will affect responses to climate change
in Sierra Nevada pines. Specifically:
is the growth, survival, and reproduction of ponderosa, Jeffrey, and
western white pines from different elevations and latitudes affected by
variation in temperature and moisture availability?
the climate already shifted enough that species could survive above
their current range limits? If so, is lack of seed dispersal or
competition from existing vegetation more important in explaining lags
in range shifts?
genes and physiological mechanisms are involved in variation in drought
tolerance between different populations of ponderosa pine?
allowing for evolutionary responses in trees change our projections of
how forests will respond to climate change - or are generation times too
long and the rate of change too fast for adaptive responses to matter?
Other questions recently investigated:
do life-history tradeoffs in time to maturity, height, and fecundity
affect plant species's potential rate of spread? Do any species occupy
the 'sweet spot' of short generation time and excellent dispersal
invasive populations of Solidago canadensis adapted to climatic
gradients in the Swiss Alps, and how might this affect their spread under
