Welcome - June edition (1 April - 31 May 2007)

Welcome to the June edition of sCRIbbles! 'Tis the season to get out and enjoy our wonderful Canadian rivers, either for fieldwork or fun, or both!

Thanks for stopping by to see the latest CRI activities,

Recent Happenings - April-May Kidd Lab

Karen Kidd and her co-authors at DFO in Winnipeg published a paper in the Proceedings of the National Academy of Sciences in May. The paper showed a collapse of the fathead minnow population in a lake that was dosed with the estrogen used in birth control pills.

The paper generated an incredible amount of media coverage for UNB and the CRI including articles with National Geographic, Science Magazine, Newsweek, New Scientist, the Globe and Mail, the National Post and 40 other Canadian papers, the London Daily Telegraph, and Forbes Magazine. She was interviewed by CTV, by CBC TV National News, and by CBC Radio (for 7 different shows including “As it happens”). Links can be found in the "CRI in the News" section below.
