Plants in ecological webs

A visit to any Botanic Garden surely means attention paid to plants – that’s what “Botanic” means, after all.  When you visit our Fredericton Botanic Garden, for example, your attention will probably first be drawn to our flowerbeds and forests; to the primulas in the Hal Hinds Garden and the daylilies in our newly expanded Daylily Bed; to the reeds by our ponds and the ferns along our Woodland Fern Trail.  All these beautiful plants are worth your time – but we hope you’ll look beyond them, too.  That’s because each of our plants is also part of a larger ecological web.

Gardens, beachheads, and invasions

A visit to a garden is a chance to see beautiful plants, and often, unfamiliar ones.  For centuries, gardeners have scoured the world for beauty that evolved in far-off lands. Many of our most cherished garden plants, then, originated somewhere else – and being the first to grow something new and strange has always been something to boast of.  The quest for new accessions is a fundamental part of gardening, and it’s fun and educational, but over the years it’s had its dark side, too.  That’s because gardening has been an important pathway for the arrival of invasive alien plants (and other creatures).

Accidental SciComm

Photos: Possibly my nerdiest T-shirt; and town of Norris Point, Newfoundland.  Both CC BY 4.0.

Recently, I had to drop off a cheque at my university’s Donor Relations office.  I was run off my feet that day, but that office is only one building away from mine, so I figured I could pop over and be back at my desk in 3 minutes flat.  I was wrong.  It was more like 20 minutes, and the extra 17 were because I was wearing my “Two bees or not two bees” T-shirt.

I wear a lot of nerdy biology T-shirts, and one of the useful (I believe) results of that is occasional bouts of what I call Accidental SciComm.  Continue reading

Three witches in the woods

Happy Hallowe’en!

Tonight, you’ll no doubt see neighbourhood children traipsing door-to-door in costume, shrieking and laughing along the way.  You’ll see superheroes and scarecrows, pirates and police officers, wizards and witches. Some costumes go in and out of fashion; but there are witches every year.

There are witches in the woods, too. Continue reading

Why is our Garden green?

It’s spring, and our Garden is beginning to turn green.  That sounds utterly unsurprising; and yet, lurking in that simple observation is one of the deepest mysteries in the science of ecology.  Why, exactly, is the world green? Continue reading

The botany of henna

Henna-based body art has thousands of years of history in India, Africa, and the Middle East, and it’s an increasingly common sight in the Western world too.  The intricate designs are beautiful, and many traditional designs are packed with symbolism and story.  But the henna itself has a story, too – a botanical one.  For those of us who love plants, history, and naming, there’s a lot to like about henna.

Life under the snow

             On a cold February day, when breath hangs visible in the frigid air and even our winter-resident birds are huddling out of sight, it’s easy to think that life outdoors waits suspended for a thaw.  Think twice, though, because when that thaw comes it will bring evidence – like the networks of vole tunnels in the photo above – that this apparent suspension was just an illusion.  There’s a lot going on, even on the coldest days of winter; but a lot of it is happening out of sight, under the snow.
