Interesting new paper – maladaptation in resurrected Daphnia from heavy metal contaminated sediments

A dispatch article (“A crustacean time capsule” by P. Monahan) in Frontiers in Ecology and the Environment highlights a new paper (Rogalski. 2017 American Naturalist ) that examines maladaptation in resurrected populations of Daphnia ambigua to heavy metal contamination in lake sediments.  These results are quite interesting and puzzling at the same time.

Congratulations are in order!

Congratulations to Emily Kiehnau on receiving both a summer 2017 and academic year 2017-2018 Adams Scholarship to support her research on the interactions of the spiny waterflea, Bythotrephes longimanus, and its Daphnia prey.
