In Manitoba, the roses aren’t red

It’s almost Valentines Day and the flower that most people associate with that holiday is bright red. Long-stemmed red roses have long been the flower of choice for people wooing their sweethearts. But if you’ve ever gone hiking in a wild Manitoba grassland or forest, you might have noticed that the roses we have here are pink, rarely white, but not red. In fact, there are no bright red wildflowers in our province. Why not?

Why Flowers Have Colour
To understand the lack of red flowers in Manitoba, we need to think about why flowers exist at all. Flowers are the reproductive organs of plants; they produce eggs and/or pollen. Since plants can’t move around to find a mate, they often use animals to move the pollen from one flower to another. Successfully transferred pollen fertilizes the eggs of the receiving flower. To attract animals, plants grow structures that animals will find attractive, like beautiful or unique scents, and petals with eye-catching colours.  They also usually reward the pollinator with nectar.

The Nature of Colour
Colour exists because different surfaces reflect different wavelengths of light. Light is made up of a whole spectrum of colours, evident in a rainbow or when light shines through a prism. Just like some animals have a better sense of smell than others, they also see things differently. Birds and humans can see red flowers quite well, but most insects cannot. To an insect, red is difficult (though not impossible) to tell apart from green leaves. For this reason, areas where birds are common pollinators (such as tropical rainforests) tend to have lots of red flowers. Areas with mostly insect pollinators typically have lots of yellow and violet flowers. In Manitoba, our only bird pollinators are hummingbirds, the most common being the Ruby-throated Hummingbird (Archilochus colubris).

Abundant Insect Pollinators

Insects are the most abundant pollinators in Manitoba, so most of our flowers are highly attractive to bees, butterflies, moths, flies, wasps and/or beetles. Flowers that are orange, yellow, blue and violet are most attractive to insects, as these colours are readily visible to them. However, unlike humans, insects can also see into the ultraviolet (UV) range. This ability explains the presence of so many, seemingly white flowers in the province. Flowers that we see as pure white or plain yellow, actually usually reflect UV rays, and look much different to insects than to us. White flowers are also often pollinated by moths, because white is more visible in moonlight than any other colour.

Why do cultivated roses look different from wild roses?
Humans have been cultivating roses for thousands of years. In the process, we selected features that we find attractive but that make them largely unattractive to pollinators. Colour is one factor. Insect pollinators do not usually visit red roses because they can’t see them very well. Further, cultivated roses have many, densely packed petals (not just five like the wild ones), that cover up the pollen-containing anthers, making them difficult for pollinators to access. So, the end result is that these beautiful flowers now function only as aids to human, not wild, romance.

Manitoba Tyndall Stone achieves status as Global Heritage Stone Resource through collaborative efforts of University of Saskatchewan and Manitoba Museum

(Winnipeg, MB: January 24, 2023) – A type of stone quarried only in Manitoba has found international recognition as a designated Global Heritage Stone Resource by the Subcommission on Heritage Stones. This designation provides recognition to dimension stones that have broad significance to humanity. Tyndall Stone is the only Canadian stone on this list, and it becomes a member of a select group that also includes Carrara Marble (Italy), Deccan Basalt (India) and Portland Stone (UK).
 
The nomination process was spearheaded by Dr. Brian Pratt of the University of Saskatchewan, assisted by Dr. Graham Young, Curator of Geology & Paleontology at the Manitoba Museum.
 
Tyndall Stone has long been recognized within Canada as a premier building stone,” says Dr. Young. “It is treasured both by people involved with architecture and construction, and by those of us who study the rocks and fossils of Manitoba. Since it is such a wonderfully useful material, it seemed long past the time that it should also receive international recognition, listing it with peers such as Italian Carrara marble (used in ancient Rome) and Indian Makrana marble (used in the Taj Mahal).”

The Subcommission on Heritage Stones, which is part of the International Commission on Geoheritage, is under the auspices of the International Union of the Geological Sciences; its purpose is to raise awareness of culturally significant building stones, and in doing so, increase knowledge and encourage conservation and protection of extraction sites.
 
 “As of early 2022, there were 22 stones designated as Global Heritage Stone Resources, and ten more were added in December 2022,” says Dr. Pratt, who has been a member of the Subcommission since 2016. “The nomination process involves a comprehensive, detailed checklist which provides the geological context and architectural uses. Tyndall Stone was an obvious candidate to be the first Canadian stone nominated because of its unique appearance and its widespread use, for example for the exterior cladding of the Manitoba and Saskatchewan legislative buildings and the interior of Centre Block on Parliament Hill.”

Tyndall Stone has been used in building as a dimension stone since the turn of the 20th century. In addition to the iconic legislative buildings in Regina and Winnipeg, monumental buildings using Tyndall Stone that were constructed in the first decades of the 20th century are distinctive elements in the centres of these and other cities and towns. These buildings, constructed when the prairie provinces were growing rapidly in population prior to the Depression, have stood the test of time and are in good condition, lending a sense of permanence. Cities and larger towns now have historical or heritage societies and, in collaboration with various levels of government, many of these buildings have been designated as heritage properties and are protected.

Tyndall Stone is a fossiliferous stone, containing abundant fossils of marine organisms such as corals, sponges, giant cephalopods (relatives of squids and octopus), trilobites (relatives of crabs and spiders), and many other forms. These date from the Ordovician Period of geological time, and lived in a tropical sea that extended across what is now North America, from Texas to Greenland, about 450 million years ago.

“For many decades, Gillis Quarries has generously provided research and collecting access to paleontologists from the Manitoba Museum, and to other scientists. Tyndall Stone is a treasure trove of fossils of Ordovician age, and thanks to the access we have been provided, the Museum has built an important collection of these fossils, which are used for scientific research, exhibits, and programs. Gillis Quarries was also very supportive of the Museum when we developed an exhibit on the history of quarrying, and the fossil panels in our foyer,” says Seema Hollenberg, Manitoba Museum’s Director of Research, Collections and Exhibits.

Tyndall Stone is a trade name that has been in use since the early 20th century, soon after quarries were opened at Garson, Manitoba, in 1895. The name is now trademarked by Gillis Quarries Ltd.

Science in the Snow

More weight equals more speed on this icy slope. ©Brandi Hayberg

By Mike Jensen, Planetarium/Science Gallery Programs Supervisor

When thinking of activities to do on a bright Winter’s day, science doesn’t usually come to mind. Surprisingly, science is at work with almost every fun pastime you can conduct out in the snow. You just need to know what to look for!

Of course, the first thing you think about as you zoom down a snow-covered hill on your favorite toboggan is physics, right? Well, it should be, because the laws of physics are actually in the driver’s seat when you are careening down a slope with no brakes. Next time you hit the slopes, conduct some experiments.

Do you go faster with more or less weight?

Does the shape or type of material of your toboggan affect how fast you go?

Does a steeper or gentler slope make a difference to your speed?

Once you are done experimenting with your sled, shore up your engineering skills by building a snowman. Surprisingly, it’s not as simple as you think. Here are some science and engineering factors to consider when making Frosty in your front yard.

  • Moisture content. Snow can be too wet or too dry, so having the right amount of water to ice crystals can make or break your construction. Water is the glue that sticks the ice crystals together.
  • Pack it down. This actually melts some of the snow, which then re-freezes and helps to bind the snow together.
  • Watch your center of mass. There’s a reason the largest snowballs go on the bottom. Don’t go making Frosty top-heavy, otherwise you risk catastrophic failure.

After you’ve had your fill, come put your new-found science and engineering skills to the test at the Manitoba Museum’s Science Gallery. Design and build your newest creation at the LEGO brickyard, or see if you can be the first to cross the finish line at the Engineered for Speed Race Track!

“Ketch” up with the Nonsuch!

Sail into the past with the Manitoba Museum’s Dr. Amelia Fay, Curator of HBC Collection, and learn more about the infamous Nonsuch.

 

This Winter Break, for a limited time only, the Manitoba Museum will be offering tours that give a rare look into the cargo hold of the Nonsuch. In light of this unique opportunity, I’d like to share some interesting tidbits about this replica ship and surrounding gallery.

The Nonsuch is a full-sized replica of a 17th century ketch that was constructed in the mid-20th century to celebrate Hudson’s Bay Company’s 300th anniversary. You may have noticed that there is no wheel to steer the ship; that’s because the original Nonsuch pre-dated the invention of the ship’s wheel! Instead, the ship is guided by the tiller, a lever that connects directly to the ship’s rudder. Imagine sailing this ship across the cold North Atlantic and into the icy waters of the Hudson Strait.

I think it would have been pretty terrifying, and the chosen captain for the replica agreed. Captain Adrian Small advised that Nonsuch be towed across the Atlantic, and it began its sailing tour of North America along the St. Lawrence River. I’m often asked why the beds in the Captain’s quarters are so small, and it has nothing to do with stature. Sleeping somewhat upright, propped up with pillows, was very common during the 17th century to help with digestion and assist with breathing. Although people were a bit shorter in the past, the difference is not that great. The average height for British men in the late 1600s was 5’5”, while today the average is 5’8”.

As you wander the gallery, take note of the sights and sounds. Extensive research went in to every prop and sound in the gallery to ensure historical accuracy. All of the dishes in the tavern are replicas of actual ceramics and pewter that have been recovered archaeologically from Deptford, England that date to the late 1660s. Enjoy your visit to the Museum this Winter Break, and get ready to wow your friends and family with your newfound knowledge!
