Congratulations to Asa and Angela!

Congratulations to Asa Candler and Angela Jarjoura for successfully defending their Honors Research Theses during the past two weeks!  The title of Asa’s Honors Thesis was:  “Enlightening discoveries: Clonal differences in phototaxis of Daphnia pulicaria isolated from Tanners Lake, Minnesota”.  The title of Angela’s Honors Thesis was:  “Climating changes: Differences in reproductive phenologies and life-history characteristics between melanized and non-melanized Daphnia pulex genotypes in response to variation in ultraviolet radiation and temperature.”  This is a great accomplishment.  We will miss you in the lab but wish you great success as you pursue your future academic/professional endeavors.  All the best!
