Last summer, during the New Brunswick bioblitz hosted by the New Brunswick Museum, the I found the first New Brunswick (and Atlantic Canada) record of Carychium minimum Müller, 1774. Read more about this in the short article published in Check List, the journal of biodiversity data. I am both a subject editor (for Mollusca) and the graphic editor.
Carychium minimum was collected along the shore of Mactaquac Lake, a widening of the Saint John River, upstream from Fredericton (45°52′06.5″ N, 055°44′44.6″ W.
My map of all North American records (that I know of) shows that this species is rather widely dispersed in Canada and the U.S.

One of the malacological highlights of my recent trip to New Brunswick was to see live Arianta arbustorum, the Copse Snail. I’d seen this species alive in Germany and England but not previously in North America. Last year (2012), I had looked for it while in St. John’s, Newfoundland, but failed to find it, having only a sketchy idea as to where to look.
Arianta arbustorum, Saint John, New Brunswick
Arianta arbustorum was an early introduction to North America, having been found in Newfoundland in 1885. But, it was only many years later that the populations were reconfirmed. Donald McAlpine et al. (2009) reported locations in Newfoundland, New Brunswick and Ontario. Included in their records was the site that I visited: behind the New Brunswick Museum collections building on Douglas Avenue, in Saint John, and where the snail I photographed originated.

In June 2013, I participated in the annual New Brunswick Bioblitz, which is organized by the New Brunswick Museum. This year the two-week long bioblitz was focusing on the Grand Lake Natural Protected Area (NPA), southeast of Fredericton, NB. Check out the Bioblitz’s blog here. Next year’s bioblitz will again be in the Grand Lake NPA. Continue reading →
