Sep 22, 2012: Populus tremuloides

Populus tremuloides

It's been a long time since I've shared an image like this. In the past, they have provoked reactions along the lines as to what an image like this has to do with botany. It's hard to argue against that point, so my only excuse for sharing it is that it's a weekend before I'm out of the office for the next week, and I don't have time to write much.

For your reading fix, I suggest visiting the Art Blog of Jonathan Jones, with a recent assertion: Science is More Beautiful Than Art. If I recall correctly (the past week has been a blur), the article was forwarded to me by UBC Botanical Garden's new Artist-in-Residence, Dana Cromie.

Speaking of blurs, that is how today's photograph was made--a long-exposure smooth panning motion on some poplar trees in Jasper National Park.

Sep 22, 2011: Loch Maree, Scotland

Loch Maree, Scotland

It's been one of those kind of weeks at work, so apologies for too few entries. On the other hand, a nod of appreciation to boobook48@Flickr (aka Lorraine Phelan) for sharing this photograph of a serene scene from Loch Maree, Scotland. Thank you!

Wikipedia provides a well-rounded look at the historical and biological importance of Loch Maree, so that's worth a read.

Broadly distributed through much of Eurasia, the Scots pines of Loch Maree represent, I suppose, the northwestern present extent of the species, though there are a few populations further west in Portugal and Spain, and it is found further north throughout Scandinavia, Finland and Russia. It also previously occurred naturally in Ireland, but was extirpated there. The Loch Maree population is special; to directly quote The Gymnosperm Database entry for Pinus sylvestris: "Trees from the extreme west of the range, in NW Scotland (Loch Maree area, Wester Ross)...show resin chemistry and adaptations to oceanic climates not found in the rest of the species' range. These trees are thought to have survived the ice ages on nunataks off NW Ireland and/or W Scotland, or are possibly derived from Spanish populations (Forrest 1980, 1982; Kinloch et al. 1986); as yet there has been no research as to whether this small endangered population deserves taxonomic recognition."
