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.
