How can one day of field work on a Carleton off-campus program lead to a publication in a peer-reviewed journal? Join Carleton Connects with guest Mark McKone (Towsley Professor of Biology and Research Supervisor of Cowling Arboretum) as he explains the genesis of a paper in the New Zealand Journal of Ecology with five student co-authors. The central research focus was the evolutionary reason that sexual reproduction is maintained in so many wild species, even though asexual reproduction is an alternative with distinct fitness advantages. The group took advantage of a model organism for research on this question, the aquatic New Zealand snail Potamopyrgus antipodarum. Both sexual and asexual forms of the snail occur in the lake we studied, and we uncovered strong evidence to support the "Red Queen" hypothesis for the advantage of sexual reproduction. (Yes, that Red Queen, from Alice Through the Looking Glass.)
