Identifying a Ghost Plant

A week ago I posted a blog about a rare plant that I had been searching for in the West Hawk Lake area: climbing fumitory. Since then I’ve had several people ask me how to tell this plant (shown in in the picture above) apart from other similar species. In Manitoba there are only five species in the fumitory family and they are fairly easy to tell apart: two are…

In Search of a Botanical Ghost

Eighty years ago, Manitoba botanist Charles W. Lowe collected a plant from the West Hawk Lake area, not realizing that it would be the last time anyone would collect it in this province again. This June, I embarked upon a journey to see if that elusive plant was still hiding somewhere in Whiteshell Provincial Park. My scholarly journey commenced when I began working on a revised Flora of Manitoba; a…

Getting to Know Manitoba’s Wild Lilies

We share our world with billions of other organisms and they play a crucial role in our survival, providing the ecosystem services that keep us alive: making oxygen for us to breathe, filtering toxins from our water, and providing shade for us and our homes to name a few benefits. With so many cultural events being cancelled this year due to Covid-19, you may be planning on spending some time…

Beautiful Parasites (and a couple ugly ones too!)

It is pretty well known that plants differ from animals due to their ability to make their own food using just carbon dioxide, water and sunlight through a process called photosynthesis. But some plants are a bit lazy and figured “why should I make my own food like a sucker when I can just steal some from my neighbor?” Thus, the strategy of plant parasitism was born. The secret to…

Tree Tales: Canada’s Threatened Trees

Canada’s trees have developed some resistance to native diseases and insect pests. However, climate change has been facilitating more forest damage. For example, the native Mountain Pine Beetle (Dendroctonus ponderosae) used to be held in check because it was killed by extremely cold winter temperatures, which occur less frequently now than they used to. Additionally, in the last 125 years, the importation of live trees and untreated wood from other…

Satellites in a train

Winnipeg residents have been reporting some unusual sightings in the night sky over the past few days. Bright star-like objects have been seen moving across the sky, following each other in a train. Sometimes half a dozen or more of them are visible at the same time. What are these? Unfortunately, they won’t be “unusual” for very long. These are the StarLink satellites, launched by Elon Musk’s Space-X to deliver…

If a tree falls in the forest

We humans tend to think that diseases affect only animals but plants suffer from them as well.  Diseases are caused by microscopic animals (like parasitic worms), fungi, bacteria and viruses and they affect animals, plants, fungi and even some species of bacteria (viruses that infect bacteria are called bacteriophages).  But it’s not just microorganisms that parasitize species; larger organisms do too. Some fungi are parasites of other fungi and some…

A BRIEF HISTORY OF INDIGENOUS AGRICULTURE

One of the most significant contributions that America’s Indigenous peoples have made is with respect to agriculture. Many of our most beloved foods (e.g. chocolate, potatoes, corn) are native to the Americas, being initially cultivated or domesticated by Indigenous farmers. Ancient Agriculture Indigenous agriculture has a long history with the most recent archaeological evidence suggesting it has been practiced in the Americas for at least 10,000 years, almost the same…

Possible meteor outburst – November 21, 2019

Thursday, November 20, 2019 may provide a rare meteor outburst – but only for a few minutes. The annual Monocerotid meteor shower normally produces about 1 or 2 meteors per hour – and that’s if the sky is dark with no moon. It’s not something some skywatchers would even bother to put on the calendar. In the last couple of decades, however, astronomers have begun to understand meteor showers in…

I once caught a plant that was this big

This summer I spent some time doing what badgers do: digging. What was I digging for? Plant roots. Usually when I collect plants for the Museum I take only a few stems of the above ground portion so that the plant doesn’t die. But this time I needed roots: long ones. I thought that digging up roots would be pretty awful but the soil was sandy, the weather co-operated and,…
