We continually produce new knowledge that is published in the scientific literature. Our scientific productivity in botany, zoology, mineralogy and palaeobiology result in 50–60 manuscripts each year; a full list is in our annual report.

We ask our research experts to have their best publication considered for the annual Brock Award, the museum’s internal prize for excellence. This healthy competition has gone on for over two decades and is named after a former leader of the museum, Reginald Walter Brock, Ph.D.

As a past Director (1907–1914), Brock was responsible for moving the early collections into the museum’s then-new building, and for recognizing and rewarding excellence in his scientific teams. One of Brock’s rituals was to award a can of tomatoes for great accomplishments in field work. We carry on this charming tradition.

The Brock Award for a scientific publication in 2013 was awarded to Natalia Rybczynski, Ph.D., for her publication Mid-Pliocene warm-period deposits in the High Arctic yield insight into camel evolution (produced with colleagues J. Gosse, R. Harington, R. Wogelius, A. Hidy and M. Buckley).

In this paper, the team reports their discovery of 3.5 million-year-old fossil material from the Strathcona Fiord area of Ellesmere Island, Nunavut, in the High Arctic.

Rybczynski knew they had found a piece of the right tibia (lower leg) of a large mammal, but it took the help of new technology (called collagen fingerprinting) to be sure that they had found the remains of a relative to modern-day camels.

The habitat includes larch trees and the depiction is based on records of plant fossils found at nearby fossil deposits. Image: Julius Csotonyi © Julius Csotonyi

The findings add significantly to our data on the evolution of camels and help us understand the origin of anatomical specializations seen in modern camels. The work of Rybczynski and her team also adds to our knowledge of this ever-changing region of our country.

Build Your Own Museum

What do colourful stamps from Tannu Tuva, a vintage 1926 Marmon, human teeth and pencils have in common? They are all things that people collect.

Stamp and antiques collecting are fairly common, but did you know that Peter the Great collected teeth? In addition to being a professional czar, he was also an amateur dentist.

And as for pencils, there is even an American Pencil Collectors Society.

This human desire for collecting is so common that the Russian scientist Pavlov (dogs, bells, conditioned response) thought it was a basic and universal human instinct.

If you like collecting things from nature like rocks and fossils, or bugs and bones, you should come on down and check out the Trading Post at the Canadian Museum of Nature!

Unlike the more traditional, didactic museum displays with which we are heartily familiar (evolution from Eohippus to the modern horse), the Trading Post allows you to “build your own museum”. It connects visitors with their own experiences. Visitors trade what interests them, not what the museum wants or asks for. Nor do we tell you what to learn about what you collect—that is up to you.

By appealing to the five senses, the Trading Post promotes the use of multiple learning styles. Images: Martin Lipman © Canadian Museum of Nature

On a recent Saturday, for example, one little girl traded a mermaid’s purse, the jawbone of a sheep, a sea urchin, and some rocks that she found on a beach in Newfoundland during her summer vacation. She brought these specimens into the Trading Post, and through the point system, she was able to trade for some minerals that she wanted to make into jewellery.

A child looks at an array of mineral specimens in trays.

Rocks and minerals are the items most-often traded, followed by shells, fossils and insects (dead and prepared). Image: Martin Lipman © Canadian Museum of Nature.

You don’t have to trade to make a “nature exchange”: you are welcome to just bring an object in and share with us the information that you have about it. (One woman said to me last Saturday, “I can tell that’s a beaver skull. My parents found one when I was a kid. I used to bring it to show and tell every year, ’till the other kids got sick of it”.)

Or, if you are a bird watcher, you can bring in pictures of the birds you spot. Or you can make a study project of object(s) you have found, just like a real naturalist would. To each his or her own… museum!

Throat-Singing Karaoke?

While the connection between Inuit throat singing and the natural history of the Arctic may seem a little obscure at first, it is a story of synergy, opportunity and just plain fun.

During our Extraordinary Arctic Festival in April 2013, the Canadian Museum of Nature partnered with the Ottawa Inuit Children’s Centre. A variety of local Inuit singers, drum-dancers and Inuktitut language teachers from the centre presented aspects of Inuit culture to museum visitors.

The Inuit Youth Performers led by Lynda Brown participated in the festival. In addition to demonstrating the unique Inuit performing arts, Lynda explained a little of the history, tradition and playfulness of throat singing.

Throat songs are usually done by pairs of singers. Some songs are lullabies, some imitate sounds in nature, and some are a game where the winner is the last person to laugh.

Throat singing was traditionally done by women while men were hunting. Today, both men and women throat sing and often weave throat-singing techniques into contemporary Arctic music.

As part of the performance, Lynda encouraged the audience to try throat singing. She taught us how to sing in a “monster voice”. The youth performers then helped us try to throat sing as a group. We sang, we laughed and we also learned about Inuit culture and traditions that are so closely linked to the Arctic landscape and wildlife.

Lynda Brown and Heidi Metcalfe-Langille demonstrate throat singing.

 

Soon after that festival, the museum had an opportunity to partner with Science North to create Arctic Voices, an exhibition about climate change in the Arctic. We were keen to share our expertise in Arctic natural history and showcase our extensive collection of Arctic plants and wildlife.

It was also important to make sure that the exhibition was relevant to visitors who have never been to this remote and largely inaccessible part of the world. As such, the exhibition development team wanted to know what we had learned during our Arctic Festival. What activities helped create unique and memorable experiences for our visitors? Not surprisingly, the throat-singing performance with the Inuit Youth Performers came to mind. Science North had experience programming interactive exhibition components with a record-and-play-back technique; they suggested trying to create a karaoke-type kiosk.

When we proposed this to Lynda, she was immediately on board and full of ideas. She enlisted the equally enthusiastic participation of her singing partner, Heidi Metcalfe-Langille.

During a day of filming in the Mammal Gallery at the museum, Lynda and Heidi demonstrated a number of traditional throat songs with great skill, comfort, humour and ease.

Then we tried filming the interactive component. We stumbled, filmed several takes, and were not exactly sure how or if it would work. Truthfully, I felt like I held my breath until Science North’s audio-visual magician Mike Palumbo showed us the final result. The throat-singing kiosk works and is almost as fun as singing with Lynda and Heidi in person!

Try it out and tell us what you think!

Travelling Exhibitions Are the Best Way to Interact!

While I was busy taking down the Creatures of Light exhibition, with my hands deep in dust, I noticed that although the museum hosts a great many travelling exhibitions from various museums, few people know it also produces its own travelling shows! Have you ever noticed one of these exhibitions from the Canadian Museum of Nature in your vicinity? The exhibits department where I am completing my work term offers “turnkey” exhibitions that are ready to travel anywhere in Canada.

An exhibit module in the exhibition.

One person’s discovery is another person’s windfall

As I worked on various travelling exhibitions, I realized they had a lot to bring to communities and institutions. Indeed, if you don’t get the chance to come to the Canadian Museum of Nature in person, these shows get around and keep you informed about our collections, research and expertise. They are considered a way of sharing resources throughout the country, and can also be seen as a way for institutions to interact between themselves. It makes things easier for those hosting our exhibitions, because they need only to plan the space required to host the event. Isn’t that a great idea?

In the following video, the director of the Peterborough Museum & Archives, Susan Neale, shares her views and speaks about the benefits and interest generated by the exhibition Canada’s Waterscapes.

See visitors to Canada’s Waterscapes interacting with the exhibits, and hear museum staff describe the exhibition’s success and impact and comment on the positive behind-the-scenes experience.

An impressive amount of work goes into creating a winning tour

This year (2014), the travelling-exhibition programme is celebrating its 41 years of existence, and its success can be attributed to Rachel Gervais, the programme coordinator.

Before working with Rachel, I never realized the amount of work put in over all these years to come up with content, modules, specimens and educational activities that can be adapted to various audiences and exhibition venues such as museums, libraries, interpretation centres and schools. This colossal task includes planning venues and ensuring that each travelling exhibition is delivered and returned in good condition with no parts missing.

Thanks to the Canada’s Waterscapes exhibition, you can discover true-to-life specimens and impressive modules. This type of life-sized exhibition is great for any large venue and comes with all the structures needed to set up the exhibition in a flash. Image: © Canadian Museum of Nature

Personally, when my work term ends, I’m going back to Montréal to check out the cultural venues in the area in the hopes of seeing one of these travelling exhibitions! With 16 full-size exhibitions and more than nine suitcase exhibitions on tour, you are sure to come upon one of them in your vicinity. Your municipal library might just be the next venue hosting one of our exhibitions in the near future!

Illustrations from Sir John Franklin’s 1823 Book

Last week, my colleague Elizabeth Debeljak showed us a book from the museum’s Rare Book collection, Narrative of a Journey to the Shores of the Polar Sea, in the year 1819, 20, 21 and 22, by Sir John Franklin.

This week, I thought I’d give you a good look at some of the beautiful illustrations that this 190-year-old book contains. This is just a selection of the aquatint prints and engravings.

Plate titles are provided as they appear in the book’s List of Plates.

A Rare Book by Sir John Franklin Expedition Receives TLC

Since September’s discovery of HMS Erebus, believed to be the ship on which Sir John Franklin died, one of our rare books has stepped into the spotlight.

Narrative of a journey to the shores of the Polar Sea, in the years 1819, 20, 21 and 22 was written by Sir John Franklin in 1823, after his first two expeditions in the Arctic.

In October, it made local news and was showcased during the museum’s open house of its research and collections facility.

As you might imagine, leather binding dating back some 190 years requires a little TLC. The book’s cover was detached and slowly deteriorating to powder (red rot); it would not stand up to much more handling without accelerating the deterioration.

Although our rare books are kept in a climate-controlled room and handled with gloves, the preservation of these materials also relies on occasional special treatment. We commissioned Kyla Ubbink, an Ottawa paper conservator, to bring our book back to life.

Treatment was extensive. It included consolidating and treating the red-rotted leather, repairing tears, creases and fraying threads, refolding the maps to fit within the dimensions of the book, flattening the curled-in corners of the cover, surface cleaning and brushing to remove debris and dirt, and other binding repairs. Conservation treatment such as this takes time, glues require time to set and each step is meticulously completed before the next one can begin.

One of the maps unfolded from the book.

The book contains four engraved maps. They had to be folded to fit well inside the book and thus be protected. Image: Kyla Ubbink © Canadian Museum of Nature

Beautifully encased and resting on a brass-accented support, the book can now be seen in the new exhibition Arctic Voices. Our exhibition team anxiously awaited the book’s return after conservation treatment to choose the plate that would be shown. They settled on “View of the Arctic Sea, From the Mouth of the Copper Mine River, Midnight – July 20, 1821″. It was not an easy choice; the plates are all so stunning.

Reading passages from the book, I was immediately immersed in a time long ago. The narrative and descriptions of time and place make it an easily consumable read, while the seemingly poetic free-verses add artistic expression in just the right amount.

The text can be found online, but I highly recommend seeing it in person. After Arctic Voices closes on May 3, 2015, you can make an appointment to see it at our library. You may even enjoy some of the other gems of the Rare-Book Collection.

Expedition to Davis Strait: Rough Seas, Cod-Liver Sandwiches and a Highly Diverse Marine Ecosystem to Study

The morning of October 21 was bright and cold in Nuuk, the capital of Greenland, when I boarded the plane for Iqaluit, Baffin Island. This was the last leg of my trip home. It was −18°C in Iqaluit when we arrived and Baffin Island, like Greenland, was covered in a surprisingly thick blanket of snow.

Arriving—at last!—at Baffin Island, Nunavut. This is the last leg of my trip home after a thirty-two-day trip; most of it spent at sea in Davis Strait. Image: Noel Alfonso © Canadian Museum of Nature

I was very glad to be heading home after thirty-two days away, almost all at sea in Davis Strait on a former commercial trawler retrofitted with a science lab. I was there at the invitation of Fisheries and Oceans Canada in the company of Greenlandic and Danish/Faroese crew and officers, as well as five other Canadians who made up the science team.

We were there to assess the population of Greenland Halibut, the main objective of this expedition, and to generally study the fauna of the strait.

The Greenland Halibut (Reinhardtius hippoglossoides) is the most abundant fish predator in the northwest Atlantic since the collapse of the Atlantic Cod (note the large mouth and sharp teeth). The main objective of this research cruise was to assess the numbers and size distribution of the Davis Strait population. Image: Noel Alfonso © Canadian Museum of Nature

The concerns I expressed in an earlier blog article were well founded. The seas on this year’s trip were very rough in the first few days. I saw waves off the stern of the ship that I estimate at 10 metres. The anti-nausea medications I had were ineffective and Gravol simply put me—instantly—to sleep. I was extremely nauseous and yes, was sick a few times. But overall, I was fine.

I did, however, have a bit of trouble getting accustomed to the traditional Danish food on the ship. A typical supper was an open-faced sandwich of sliced raw onions, tomatoes, cheese, mussels and cod livers. Being on the ship and working twelve-hour shifts seven days a week for that length of time was sometimes challenging. While sitting in my 6′ × 6′ cabin, I would often think of my family and friends back home. However, the rich marine life I saw more than made up for the hardships.

In illustration of a fish.

Trawls were done round the clock to make the best use of our time in Davis Strait and to further the objective of counting Greenland Halibut and generally study the fauna. There was always a science crew of three on duty, nights and days. My shift was from 6 AM to 6 PM. The timing between trawls varied from the distance travelled between sites and the depth of the trawl. The deepest one was 1500 m, so getting the net down took more than twenty minutes and bringing it up could take forty-five minutes.

When the trawl came aboard, the contents of the net would be dumped into the below-decks processing area, where everything—Greenland Halibut, other fish species and all invertebrates—would be weighed and measured. DNA samples were taken for Greenland Halibut and some shrimp species.

Collectively, this will be masses of data that the Canadian department of Fisheries and Oceans will use in managing fisheries, present and future, in Davis Strait.

I had no idea that the benthic environment was so diverse in those cold dark waters. There are both small, delicate deep-water corals and large, robust ones. Cold-water corals do not contain symbiotic algae and so do not require light from the sun to live. They can be found as deep as four kilometres!

Other invertebrate species included pink anemones, sea stars, basket stars and over a dozen species of sponges, ranging in size from coffee cups to beach balls. There are isopods, amphipods and many species of shrimps, squids and even octopuses! It is really hard for us terrestrial humans to imagine this rich ecosystem down there, but it exists and I have had a part in documenting it.

Bottom: Bathypolypus arcticus is a long lived, slow growing deep-water octopus species. It eats basket stars (top left), which is unusual for cephalopods.

I brought back an impressive diversity of species for the museum: 71 fish specimens and 119 invertebrate specimens. Some of the fish species, such as the Black Snailfish (Paraliparis bathybius) and the Portuguese Dogfish (Centroscymnus coelolepis), were new to the Arctic collections at the Canadian Museum of Nature

Also, we are adding specimens for species represented so far by one, two, or just a handful of individuals. Our museum will keep samples of DNA from the fish species that I collected. So our already world-class collection of Arctic fishes is now even better and we have added tissues from a rarely visited region to our DNA collections. All in all, a worthwhile expedition!

Portuguese Dogfish (Centroscymnus coelolepis). This species is found at depths below 400 m, and down to abyssal areas to 3600 m (among the deepest known records for any shark species). It is both an active predator, eating fishes (including other sharks), squids, octopuses and gastropods, and it also scavenges on whale carcasses. We did not already have a specimen of this species in the museum’s collections. Image: Noel Alfonso © Canadian Museum of Nature

Adventures in Argentina: Museo de La Plata and an Excursion into the Permian Period

Research advances are not just made in the field, but also by collecting data from other museum collections. Scott Rufolo brought useful information back for the Canadian Museum of Nature from recent travels.

This autumn, I attended a meeting of the International Council for Archaeozoology, which was held in Mendoza Province of Argentina. I will talk about this experience in a future entry, but for now, I’d like to share some tales of my palaeontological adventures in Argentina.

Depending on the nature of their iron content, the volcanic ejecta weathers into varying shades of red, grey and black, which contrast beautifully with the greenish yellow of the vegetation.

Being in that country for the conference afforded me the opportunity to make a professional visit to Museo de La Plata, South America’s largest natural-history museum, as well as take some vacation time in order to explore several of Argentina’s other wonderful museums and palaeontological sites.

Collage: Exterior of Museo de La Plata and a sculpture of Smilodon.

Having frequently visited the New York Public Library when growing up, the entrance of whose main branch is guarded by two magnificent lion sculptures, I have always had a fondness for monuments in the shape of great cats. But as you can see here, the ones at Museo de La Plata aren’t just any old big cat sculptures. Rather, they’re representations of Smilodon, the sabre-toothed cat that stalked the ancient grasslands that were the precursor to today’s Pampas region of eastern Argentina.

As a research assistant with the Palaeobiology Section of the Canadian Museum of Nature, I work closely with our dinosaur palaeontologist Jordan Mallon in order to support his research endeavours. Jordan is particularly interested in the ecological role of the feeding behaviours of Late Cretaceous dinosaurs found in Alberta, and so is always on the lookout for new data concerning the teeth, jaws and skull shape of the various species of duck-billed and horned dinosaurs that once roamed western Canada.

The size of the teeth and the bones of the skull may be related to the mechanics of biting and chewing, so measurements may furnish information about the probable diet of these herbivorous animals.

In the first half of the 20th century, the Royal Ontario Museum traded the fossil skulls of three Canadian dinosaurs, two ceratopsians (the horned dinosaurs) and one hadrosaurid (a duck-billed dinosaur), for specimens from South America. Two of these, examples of Centrosaurus apertus and Prosaurolophus maximus sent to Argentina in 1944, wound up at Museo de La Plata in the city of La Plata, located southeast of Buenos Aires.

The whereabouts of the third—a Chasmosaurus skull traded around 1932—are unknown, but it is likely in either Buenos Aires or Rio de Janeiro. No descriptions or measurements of these specimens have been published to date.

Founded in 1888, Museo de La Plata [website in Spanish] houses over three million natural-history specimens and archaeological objects. The beautiful building sports a neoclassical exterior that shelters an interior replete with many architectural elements and exhibition cases that preserve their Victorian-era charm.

The Centrosaurus and Prosaurolophus skulls were put on display for the first time during a renovation of the palaeontology halls about 10 years ago, where they remain today. I was able to examine and measure them on a Monday, when the museum is closed to the public.

Neither had been cleaned since initially being placed on display, however, so there was quite a layer of dust coating them. In fact, such an amazing amount of dust can accumulate in a decade that it was (almost) like having to excavate them all over again! Through much sneezing and watering of the eyes, I measured, drew and photographed the two skulls.

The resulting metrical data will be added to Jordan’s database for Late Cretaceous dinosaurs of North America, and we also hope to generate three-dimensional computer models of the skulls from the photographs. Moreover, I dutifully set the collections manager for vertebrate palaeontology at the museum on the hunt for any information that he may be able to find about the location of the missing third skull. Hopefully, he will soon report back with some useful information dredged up from the museum’s archives and gleaned from conversations with South American colleagues.

Before leaving Argentina, I was able to visit several sites in Mendoza Province with exposed tetrapod trackways dating to the Permian Period (approximately 250 to 300 million years ago).

In Buenos Aires, I was certain to spend a day at the Bernardino Rivadavia Natural Sciences Museum, whose exhibitions include mounts of many of the distinct species of South American dinosaurs and prehistoric mammals.

I leave you with more photos to enjoy from my travels to these places—quite a few, in fact. I hope you’ll forgive me, but Argentina is blessed with a wealth of natural beauty and great museums, so it was hard to limit myself to just a small number.

Next time, I’ll share some pictures of the flora and fauna I encountered, including a bold, cookie-eating troop of coatis and a tiny relative of the guinea pig that raided our lunch with just as much gusto!

The Mars Diaries—two weeks at a space station in Utah

Museum botanist Paul Sokoloff is completing a scientific “vacation”…at a Mars simulation station in the deserts of Utah! Here he shares some daily diary entries that cover his two-week experience.

Day One

Stepping through the airlock to the Mars Desert Research Station (MDRS) made it all real. We arrived at the MDRS on the evening of November 15, and introduced ourselves to crew 142, the outgoing expedition that had opened the “hab” (the station’s base) for the season two weeks previous. Just as with my own crew two days earlier, we all made fast friends. Crew 142 briefed us on the various ins-and-outs of the “hab”, and we celebrated the completion of their mission with a pizza dinner from the only pizza place in town.

Day Two

After crew 142 departed this morning, our team sat down to plan out the two-week rotation. Sounds like a lot to do, and the crew is looking forward to beginning our research projects. With one last night free before the simulation begins, we headed out at night to practice a little astrophotography—the night skies here are spectacular!

Day Three

Our first full day in “sim” (simulation) started off as all days do on Mars—with coffee! It was our first day for an EVA (extravehicular activity or “space” walk); the four-person EVA team took nearly an hour to suit up while familiarizing ourselves with the gear. After a five-minute cycle in the airlock we stepped out onto the surface of “Mars”! We spent the next two hours tromping around the desert collecting plant and rock samples, and performing basic maintenance around the hab. The time passed quickly, and before we knew it, it was back to the airlock to return —EVAs are as tightly controlled here as they would be on Mars. The day ended with the team huddled around our laptops pounding out reports; on Mars, communication with Earth would be limited each day, and a two-hour window of time in which to file our daily logs simulates this.

Day Six

A documentary crew from Earth visited us today. They seem like hardy folks—they could even walk around the “Martian” landscape without pressure suits. They must be some sort of advanced robot…I kid you! The crew was from the French channel Arte, who came to interview an MDRS crew for a documentary series on manned spaceflight. They were keenly interested in what we were doing, and more importantly, why we were here. For each crew member, the answer was remarkably similar—because the work we do at MDRS gets humanity one step closer to space, and to Mars.

Day Seven

Today was my day off. Well, sort of. As part of the simulated mission parameters, we are restricted to one EVA for the crew per day, and the outside team has to be back in the hab within four hours. On top of that, only four crew members are permitted to be on EVA at any one time, so “Mars” walks are very tightly planned around here. Each person does something different when they stay in the hab. Some work, some clean, some catch up on sleep. Today, with a relatively free schedule, I cooked and surprised the incoming EVA team with homemade pizza!

Day Eight

As the crew’s botanist, and its health and safety officer, you’d think I’d know better than to pick up a cactus in the desert, even while wearing my suit gloves. But no, I had to go and collect it. I spent a good 20 minutes picking stinging hairs out of my hand once we got back to the hab. Still, today was very productive—a team of four, including myself and our resident geologist, Paul K., proceeded on ATVs to Tank Wash Stream north of the hab. This was a very rich site for our scientific projects, and at the end of the EVA
I entered the airlock with an overflowing bag of plant specimens.

Day Ten

Another Martian day, another productive EVA. Fun Fact: on Mars a day is called a sol, and is 37 minutes longer than a day here on Earth. Today we collected geological and biological specimens close to the hab, and as has happened often on this trip, I’ve been pleasantly surprised by the biodiversity in the desert—everything from great swaths of lichens blanketing sandstone boulders, to many species of the legume genus Astragalus (the group I studied for my Master’s degree), and even cyanobacteria growing inside rocks collected out in the desert. The biodiversity I was less pleasantly surprised to find was the rat we discovered scampering about the hab!

Day Eleven

It was hard prying myself from my bunk today after a late night joking around with the rest of the crew. We’ve only known each other for 11 days, but throwing a bunch of highly motivated individuals into an isolated hab, while on a simulated space mission, has a way of turning out a batch of very fast friends. Our second media crew dropped by, this time from the magazine Paris Match. Our discussions touched on everything from advanced propulsion systems for Mars missions to the ethics of transporting Earth organisms to the Red Planet.

Day Twelve

I can’t believe how quickly the time has gone —while it feels like we just got here, crew 143’s simulated Mars mission comes to an end tomorrow. Our rotation at MDRS will continue until Sunday, giving us time to wrap up our final reports, clean the hab, and brief the incoming crew 144, but the simulated Mars mission will be over, and we’ll be free to come and go from the hab at will, “sans” spacesuit. Fittingly, our last full day in “sim” is Thanksgiving here in the United States, and in honour of our American commander, we’ll be celebrating with a Thanksgiving Dinner on “Mars”. I know I speak for the entire crew when I say we are very, very thankful to have been a part of this ongoing mission to prepare humanity for its next great step.

This month, I was proud to be part of an amazing celebration at our museum—a night to acknowledge, through the first Nature Inspiration Awards, some amazingly creative, innovative and forward-thinking people and organisations. All are making a difference in our understanding and appreciation of the natural world.

That is something that we, as Canada’s national museum of natural history and natural sciences, have been doing for more than 150 years—whether it’s through developing galleries and exhibitions; working with partners to create programs that engage and inspire others, or contributing knowledge through our national collections and scientific research and expertise.

It’s been a whirlwind year since the museum conceived and put into place these first annual awards. We were delighted to receive 34 nominations last spring and I know that our jury had a hard time winnowing down the list to the finalists and the winners. Our national media partners, The Walrus and the Globe and Mail, helped share the buzz to collect nominations and recognize the finalists. We look forward to building on this year’s success when our second call for nominations is launched early in 2015.

But before we get there, I want to reflect on some of this year’s finalists and recipients, as they set high standards for future nominations.

The 2014 awards went to Alana Krug-MacLeod, a Saskatoon teen who advocates for action against climate change; Mylène Paquette from Montreal, an ocean adventurer speaking up for marine conservation; Evergreen, a Toronto-based not-for profit that introduces inner-city kids to nature; Earth Rangers from Woodbridge, Ontario, a group that educates schoolchildren about wildlife conservation; and Cascades Inc, of Kingsey Falls in Quebec’s Eastern townships, a company that pioneered the recycling of paper products.

We have produced videos highlighting their accomplishments. All are inspiring and worthy of the award, but they represent just the tip of the iceberg…

Consider that in the Youth category alone, the finalists, along with Alana Krug-Macleod, included Hannah Alper from Toronto, an eco-blogger and motivational speaker; Olivia Clement from Ottawa, a fundraiser and advocate for polar bear conservation; and Miranda Anderson from Belcarra, British Columbia, who makes environmental films. What’s remarkable is their age – two of them aged 11, one aged 15 and one aged 17.

And a glance at the adult finalists shows a surprising diversity of career paths and skills: biologist Christian Artuso with Bird Studies Canada was recognized for his efforts to create a bird atlas for Manitoba; entrepreneur David Katz, from Port Moody British Columbia, has created an innovative company, the Plastic Bank, that helps reduce pollution and at the same time provides income for people in developing countries; and artist Charmaine Lurch through her work with Inner City Angels in Toronto has found inspiration in the natural world with her most recent project focussing on the importance of bees in our ecosystems.

So many great stories, and I haven’t even touched on the not-for-profits! I encourage you to read more about them and all of the finalists for these inaugural awards

So, perhaps you know a corporation, individual, youth or not-for-profit that deserves a nomination for a future Nature Inspiration Award. Let us know about them—and keep an eye out in 2015 for the next round of applications.
