This is my 100th post on Scientist Sees Squirrel. You’ll notice it hits some of my favourite themes (but not statistics; everyone needs a break sometime). I hope you enjoy it, as I hope you’ve enjoyed a few others of my first 100.
I should hate this book, but I can’t.
“This book” is Barbara Cooney’s Miss Rumphius (Viking Press, 1982; links below) – a picture book for young children that’s both lovely and profound. I read it to my son perhaps a hundred times, and if it weren’t for him thinking he’s outgrown the book (and being read to), I’d read it to him a hundred times more. I flinch every time I read it, but I keep coming back. I’ll explain both. Continue reading

Last summer, we were driving around southern Iceland, admiring the fields of lupines (beautiful, even though they’re invasive) and the gamboling sheep (also invasive, at least to the extent they’re allowed to graze free). Before long, we noticed an interesting pattern: we saw dense fields of lupines, without sheep; and we saw thousands upon thousands of sheep, in fields without lupines – but we drove for days without ever seeing sheep and lupines together.
Being a nerd scientist, I came up with a hypothesis to explain this pattern: Continue reading

In Iceland, in July, the landscape in many places is carpeted in blue. The fields of lupines (Lupinus nootkatensis) are almost impossibly beautiful*, and lupines are adored by tourists and by many Icelanders, too. But they’re not an Icelandic plant; they’re introduced and invasive. Thereby hangs a tale, and a conundrum for conservation biology.
I normally despise invasive species, as most ecologists do, but I have a lot of trouble hating lupines. Again and again I find myself smiling at a field of blue, and then catching myself with a start as I remember that they aren’t supposed to be here. I’ve had this reaction in Iceland, in New Zealand, and in my home of eastern Canada (and here’s a nice piece from Amy Parachnowitsch admitting to the same reaction in Sweden).
These beautiful lupines make obvious a serious problem in our efforts at nature conservation. It’s not a problem with conservation biology (which is the science of how to effect conservation, once we’ve decided to). It’s a problem of motivating conservation, and I think a deep philosophical one. That problem: why should we conserve natural ecosystems in the first place? Continue reading
