Research Interests
Lake sediments record the history of a lake’s development, the
history of the landscape surrounding the lake (its catchment), and the
history of climate in the general area of the lake. I am interested
in teasing out the data preserved in lake sediments that contribute
to understanding these various histories. My special area of interest
is cladocera (water fleas), which are well preserved in lake sediments.
A cladoceran assemblage for any given period of time integrates lake
morphometry, lake chemistry, and lake nutrient status. Superimposed
on these constraints are predatory effects impinging on cladocera from
higher trophic levels, therefore presence/absence of planktivorous invertebrates
or planktivorous or piscivorous fish can be inferred from changes in
cladoceran assemblages and changes in morphology of certain cladoceran
species.
