RESEARCH
I am
generally interested in understanding how species interact in
ecological communities and how those interactions are affected by
disturbance (both natural and anthropogenic), species extinctions, and
invasions. This interest is both basic (to understand how nature works)
and applied (to understand the consequences of humanity’s impact
on the world’s biota and how we can minimize them).
During my career I have been lucky to work in
collaboration with many excellent colleagues.
Although collaborative work is sometimes difficult, I think it is one
of the most gratifying aspects of scientific research.
Below you will find some pictures of organisms and
systems I have studied.
The
amancay, Alstroemeria aurea (Alstroemeriaceae), one of the
species I studied during my dissertation work in Nahuel Huapi National
Park. This species flowers in the forest undestory during the summer,
and is visited by a broad assemblage of flower visitors.
