Talking about the Arctic – Insights from Museum Directors

In January, I met with my counterparts from across the world at the annual meeting of Arctic museums in Washington, DC. It was a whirlwind 36 hours that was at once enlightening, productive, interesting and inspiring.

As directors leading major museums, this meeting is one of the few opportunities to look beyond our hectic daily responsibilities—administration, fundraising and problem-solving—to take a global look at our work. We focussed on how museums can take concrete action to contribute more to global knowledge and dialogue about the changing Arctic environment.

It helped that the meeting coincided with the Arctic Matters event of the National Academy of Sciences, and the Smithsonian’s Arctic Crashes symposium. Both of these provided a real flavour for the latest research and approaches to communicating Arctic research to experts and the public.

We also confirmed our agenda for the 2016 annual meeting of the Arctic Natural History Museum Alliance, taking place March 13 to 15 during the Arctic Science Summit Week in Fairbanks, Alaska. Our alliance will focus on raising the profile of our respective research programs during this week, and at other Arctic research forums.

We will also focus on digitizing and making our collections more accessible. With more governments committed to open data, we now have a window of opportunity to share our collections data through portals with an Arctic focus. These include the University of the Arctic’s ArcticPortal, the Global Biodiversity Information Facility (GBIF) and the Encyclopedia of Life.

Finally, we will ensure the conservation of Arctic species will have a presence at the September 2016 World Congress in Hawaii of the International Union for the Conservation of Nature.

So, a lot was accomplished. But after spending 36 hours with my director colleagues from the Swedish Natural History Museum and the Smithsonian Natural History Museum I realized a few things:

  • Natural history museums really are saving the world. Through evidence, knowledge and inspiration, we making a difference every day, and I am proud to be part of that.
  • Natural history museums collect the evidence of our natural world (our collections of specimens) and have done so for hundreds of years.
  • Natural history museums are a source of knowledge derived from the scientific study of that evidence.
  • And, ultimately, we are a source of inspiration. Inspiration to explore, to connect with, and to discover the natural world around us, all in the hope that we inspire understanding, respect and value for nature.

It sounds like a simple three-pronged approach. Simple you say? Actually…as I have found throughout my career, it becomes simple once you focus on what matters.

What matters is that understanding our natural world and how to live in balance with it matters now and in the future. That is what natural history museums do – through scientific evidence, knowledge and inspiration. How we collect the evidence depends on the types of collections we hold and study. The knowledge we create and share depends on the research expertise we have and we build over time. The way we inspire the many audiences we reach also varies by subject, location, size of space, funding, partners and governance structure.

As I look at the year ahead, and the ongoing work of the Canadian Museum of Nature scientists, I am confident that we will continue to inform global climate and biodiversity talks, and to galvanize communities to help all of us to truly be citizens working for a better natural future.

Of Fish and Men…Studying Fossil Fish in Ethiopia

It will come as no surprise that this museum knows its fish. With experts like Brian Coad and Noel Alfonso, and world-class collections, ichthyology is alive and well here. For some of us, however, acquiring a deeper knowledge of our water-dwelling friends is a newer pursuit.

Which is how I find myself writing this blog post in Addis Ababa following a week of research at the National Museum of Ethiopia. I am in East Africa studying 3 to 4 million-year-old fish from sites associated with some of the earliest human ancestors.

The main grounds of the National Museum of Ethiopia in the country’s capital of Addis Ababa.

Above the main entrance to Ethiopia’s National Museum is a beautiful mosaic depicting objects that reflect the nation’s heritage, including the bones of Lucy (as seen in the centre). Image: Scott Rufolo © Canadian Museum of Nature.

As a specialist in zooarchaeology, I am interested in understanding how people interacted with animals in the past. I analyze the bones found on archaeological sites for clues about the nature of the human-animal relationship. In prior blogs, I have mentioned my work in Syria and my hope to see zooarchaeological research return to the Canadian Museum of Nature.

In Syria, I explored the ways in which the management of animal-derived resources—meat, milk wool—evolved from the fifth to the third millennia BC. This span of time includes the emergence of the world’s first urban centres. An increasingly complex economy focussed around animal-based goods was one of several factors that contributed to the rise and success of cities.

Most of the animal bones that I identified in Syria belonged to mammals, though, so how do fish come into the picture? Well, with the current political situation in Syria, it is no longer possible to conduct fieldwork there, so I needed to find another line of research.

Scott Rufolo seated at a table, examining fish fossils.

The National Museum of Ethiopia completed construction of a new storage and research facility in 2010. Here I am in one of the study rooms working with the fish fossils. Image: Scott Rufolo © Canadian Museum of Nature.

In stepped Kathlyn Stewart, head of the museum’s Palaeobiology Section and an expert in fossil fish. She presented an opportunity I could not pass up: joining her on a fossil fish project in East Africa. So, after several months of preparation learning more about the skeleton structure and evolutionary history of fish, I am now in Ethiopia.

Working in collaboration with Alison Murray of the University of Alberta, I examined the fossils of catfish and minnows recovered from several sites located in the basin of the Awash River in eastern Ethiopia. We processed over 700 specimens, and we believe we have even identified one – perhaps two – new species. And while this is not a proper zooarchaeological project, it does have a particular relevance to the human dimension.

Many of the fish fossils are small fragments that require sorting. Here you see the contents of a large bag of fragmentary remains partially sorted into piles of identifiable and unidentifiable material. Image: Scott Rufolo © Canadian Museum of Nature.

These fossil fish once shared the landscape with early hominids, the primate family to which belong the famous Lucy (Australopithecus afarensis) and all her relatives, including us modern humans. The fish fossils reveal much about the past waterways and environment, providing more detail about the world in which our ancestors lived.

Long considered to be ancestral to the modern human lineage, A. afarensis roamed what is now Ethiopia, Kenya, and Tanzania between 3.6 and 3.0 million years ago. Image: Scott Rufolo © Canadian Museum of Nature.

In a sense, then, I have moved on to looking at the beginnings of the human relationship with fish. From neighbours in the wild to the complex set of interactions today (fish as pets, food, focus of recreational activity, etc.), we humans have a long history with the finned animals that inhabit the Earth’s waters.

Early hominids certainly encountered fish over the course of their lives, and it probably wasn’t long before fish became regarded as a food resource—or was it?

Lucy, discovered in 1972 at Hadar in the Afar region of Ethiopia, is by no means the sole fossil representative of her species. Seen in the centre of this display case is a replica of the partial skull of Selam, often called the “first child.” Discovered south of Hadar at the site of Dikika in 2000, Selam died at the age of three, and her remains are still under study. Image: Scott Rufolo © Canadian Museum of Nature.

Exactly when our ancestors began regularly eating fish is a debated topic, and one I will discuss in my next blog entry. I’m off to Kenya next to look at some additional fish fossils there, so more soon from Nairobi!

The fish remains may often be small, but they can certainly be distinctive. This is the pectoral fin spine from Clarias, a genus of catfish commonly found in the East African fossil record. You can see the articular surface to the left, where the spine attached to the body, as well as the sharp serrations that adorn the outer surface. Image: Scott Rufolo © Canadian Museum of Nature.

Studying the Enriching Effect of Submarine Canyons

Over the last seven years, Canadian Museum of Nature marine biologist Kathy Conlan and her colleagues identified more than 500 species collected in two submarine canyons on the South Australian coast, comparing the marine life inside and outside of the canyons. This and other studies are demonstrating the importance of submarine canyons to coastal marine life worldwide.

An image showing the canyon in relief.

Submarine canyons incise the shelf and slope of all the continents in the world and nearly 6000 are known so far. They are created by river flows from the continents and by sediment failures along the shelves.

Submarine canyons focus deep-ocean currents onto the continental shelves, where the currents inject nutrient-rich water at shallow-enough depths for phytoplankton to take advantage of them. They also funnel land waste downwards so that they have become a convenient underwater garbage pit. Fish tend to congregate in canyons to feed on zooplankton concentrations there, so these canyons are also a favourite target for fishing.

In 2009–2010, I took a year’s sabbatical in Australia at the South Australian Research and Development Institute with David Currie, Ph.D., and at Flinders University with Sabine Dittmann, Ph.D.

David had recently collected samples from two submarine canyons on the South Australian coast. These canyons were thought to be important to the survival of a nearby sea-lion colony and to support the lucrative tuna, sardine and anchovy fishery there.

From “Macrofaunal Patterns in and around du Couedic and Bonney Submarine Canyons, South Australia”, by K.E. Conlan, D.R. Currie, S. Dittmann, S.J. Sorokin, E. Hendrycks (PLoS ONE 10(11): e0143921; doi:10.1371/journal.pone.0143921).

David had already studied the fish and large invertebrates in these canyons. Because I specialize in small invertebrates, he generously invited me to see if they were responding in the same way.

These critters, which live on the sea floor or burrow underneath, are good indicators of environmental effects because they aren’t very mobile, so they can’t get out of the way of pollution or natural changes. So their distribution patterns would likely reflect the effects of the canyons.

Three photos: A man grasps a sampler that hangs overhead, a sampler hangs over the surface, the ship at port.

David methodically sampled inside and outside the canyons at 100, 200, 500, 1000 and 1500 m depths. He used a grab that sampled a known area of sea floor so that we would be able to compare abundance and biomass at each of the 27 sites.

That was a feat in itself: targeting precise locations from a rolling ship with a sampler hanging from a 1000 m of cable or more that frequently failed at such great depths.

My job seemed much easier: pick out of the mud the roughly 3000 animals that he had captured, then identify, count and weigh them, and finally, analyse their distribution patterns to see if we could see a canyon effect.

This looked like a simple job until I realized that Australia has a way more diverse marine fauna than Canada. Fortunately, Shirley Sorokin, Ed Hendrycks, Val Tait and Shea Cameron joined the project.

The result was the discovery of 531 species of worms, clams, snails, starfishes, sponges, shrimps and many, many more. Their abundance, biomass and diversity were highest on the continental shelf, and species composition shifted at the canyon heads.

This shift indicated that the canyon heads had strong currents that were enriching the coast. Our results were published last autumn by the open-access journal PLoS ONE, thanks to support from the Canadian Museum of Nature and a Visiting Scholar grant from Flinders University.

This collection is now housed at the South Australian Museum, where we hope it will be useful for other researchers. Our identification of such a rich area is being used as ammunition to convince policy makers to protect this coast better.

Canada has many submarine canyons of its own. Perhaps the most famous is the Gully, a designated marine protected area near Sable Island off the coast of Nova Scotia.

Canyons may be sanctuary for many undescribed species—just ask Jean-Marc Gagnon, Ph.D., a marine biologist here at the Canadian Museum of Nature who recently identified a new species of file clam from the Gully.

Catharine Parr Traill Herbarium Scrapbook Gets Careful Conservation Treatment

In museums, conservators have the privilege of working on all types of objects and artefacts, preparing them for exhibition or repairing damage accumulated over time. This autumn, I have had the wonderful pleasure of conducting a conservation treatment on a botanical scrapbook created by Catharine Parr Traill.

The National Herbarium of Canada at the Canadian Museum of Nature in Ottawa houses the largest collection of Parr Traill’s albums containing hundreds of botanical samples. The collection is one of the oldest in the museum and provides a snapshot of plant life that existed during the 1800s.

These albums have received considerable interest in recent years because of the revision of Catharine Parr Traill’s historical role as early scientist and pioneer. The book Sisters in the Wilderness, by Charlotte Grey, has also helped people get to know Parr Traill and her sister, Susanna Moodie, and their incredible story of science and survival.

On a personal level, this collection is very special. My post-secondary education at both Trent University and Fleming College in Peterborough, Ontario, put me right in the heart of “Traill country”. As a youth, I read about Catharine Parr Traill and her sister, Susanna Moodie, which helped enrich my love for the natural world.

Preserving Century-Old Albums and Scrapbooks
Catharine Parr Traill’s scrapbooks and albums have come to the attention of the museum’s conservators over the past few years because the books are extremely fragile and were at risk of being damaged every time they were taken out for viewing. Some of the plants were becoming detached, while others were being compressed in the bindings as pages were being turned, resulting in damage to the specimens. Thus, a long-term project was developed by the Canadian Museum of Nature’s conservation staff to stabilize the books so that they could be more safely handled and studied.

The staff did a survey of the needs of the collection and developed a treatment protocol. Because the work is time-consuming but not overly complicated for someone with specialized training, a programme was developed for the books and albums to be treated by emerging conservators like myself, doing internships as part of their curriculum requirements.

As a conservator-in-training, I worked on cleaning and repairing the pages, and stabilizing the specimens so that the books can be more easily handled. There is also an initiative to digitize the collection by capturing high-resolution photographs in the hope that they can be made available for viewing online, thereby making them more widely accessible while minimizing risk to the objects by limiting their handling.

The treatment of the books entails a careful assessment of each page to decide what exactly is required for stabilization. Conservation treatments should always be reversible in case future conservators are able to find better solutions. Accordingly, extensive testing is required to find the best combination of adhesives and materials to best meet the preservation needs of the artefact.

I did a lot of testing with adhesives to find combinations that would give the right amount of strength without damaging the specimens. We used a 4% methylcellulose adhesive to tack down lifting leaves. Little paper straps were made to help secure lifting stems. The straps are tiny, measuring only 1 mm to 1.5 mm in width!

Several photos showing pages with plant specimens.

The straps were made by coating Japanese paper in a special adhesive that can be reactivated with ethanol after it dries. The Japanese paper was cut into the tiny strips once the adhesive was dry. The adhesive was reactivated with a small amount of ethanol before the strap was attached to the page. Ethanol is used to limit the amount of water introduced to the old historic paper, which could leave marks or damage the paper. The results are significant for improving the overall stability of the book, while also improving the overall aesthetics.

Meeting Catharine Parr Traill’s Descendants
One of the most special days this autumn was getting to welcome Catharine Parr Traill’s great-great-great-grandnephew and his family to the Canadian Museum of Nature. It is rare that conservators get to meet the creators of the work that they are trying to preserve, so getting to meet the descendants of the creator makes the work even more special.

Several people look closely at an album.

The family came to the museum to see our scrapbooks and a copy of the first edition of Canadian Wildflowers, which is housed in our Rare Book Collection. The family also presented the Canadian Museum of Nature with a copy of their family history, which they had compiled.

During their visit, I had the opportunity to show them my preservation work to stabilize the scrapbooks. They loved seeing the inscriptions written by their ancestor and the work we are doing to promote the longevity of their heritage. It was a very special day that I will remember for many years to come.

My Irish Diatom Adventure (Part 2)

As I mentioned in a previous article, I travelled in Ireland last autumn and took the opportunity to sample diatoms. The photos here show the best of the 21 sampling locations and the resulting diatoms.

Some samples contained only a few individual diatoms, while others hosted thousands of individuals from a variety of species. Samples taken from calmer water with a muddy composition were easier to select and yielded far more diatoms than the ones taken from faster water or an area with a stony bottom.

Abbey River, Limerick

The Abbey River was my first sample location. It is a freshwater distributary arm of the Shannon River in Limerick. It eventually falls about a metre into the Shannon, which is tidal (salt water). Because the rivers were walled off (as are most of the rivers in Irish towns, I soon discovered), it was a challenge to get to the water level.

Fortunately, a friendly local couple at Arthur’s Quay helped me onto their wharf and into a row boat so I could take a good specimen. I mentioned I was from Canada, and Arthur happened to be my mother’s maiden name, so maybe that helped?

I thanked the couple and returned to the hotel for processing the samples.

On my return to Canada, researcher Paul Hamilton and I looked at the samples. Paul is a specialist of freshwater diatoms at the Canadian Museum of Nature in whose lab I regularly do volunteer work. We found freshwater and marine (salt water) diatoms in the sample, which indicates some kind of mixing—perhaps from high spring tides, wind blowing off the Shannon, or birds transporting drops of water… and diatoms.

Kylemore Castle, Lake Maladrolaun

The beautiful Kylemore Castle (shown in my previous article) is located on picturesque Lake Pollacapall and near Lake Maladrolaun. Sampling here was relatively easy. I obtained one sample from each lake, and a third from a drainage ditch. Lake Maladrolaun—and its muddy rather than stony bottom—yielded the best results.

Carrowbeg River, Westport

The Carrowbeg River flows through the town of Westport to the sea at Clew Bay on the west coast. Although the river was walled, stairs beside a bridge at South Mall and Bridge streets gave me access to the river bottom. The Carrowbeg sample yielded many very interesting diatoms.

The Burn Stream, Donaghadee

Our tour group spent an evening in the coastal town of Donaghadee, Northern Ireland, just east of Belfast. With an hour free before supper, I discovered a drainage culvert along the sea wall. Walking up some streets and with the help of locals, I found the open-stream part near Crommelin Park and took a sample at a spot just before the water disappeared into the culvert.

I later learned in an email from the Donaghadee Historical Society that the stream was called the Burn, Gaelic for “small freshwater stream”. Also, many years ago, the stream was used to power a mill and then it was culverted in the 1950s after a flood.

St. Stephen’s Green Pond, Dublin

St. Stephen’s Green Park has a beautiful large pond in the heart of downtown Dublin, the capital of the Republic of Ireland. There was easy access for samples from each end of the pond, which is shaped like a long bowtie. The pond is home to swans, cranes, ducks and other birds. While I was taking a sample, a curious moorhen came over to me to see what I was up to.

Italian Gardens Pond, Garnish Island

Garnish Island is located in the sheltered harbour of Glengarriff in Bantry Bay, in the southwest of Ireland. The island is accessible by a ferry service. Seals can be seen basking on the rocks along the way. The island has renowned gardens and beautiful walks, with a wide variety of plants and a stone lookout tower. Specimens were taken from the Italian Gardens Pond and two other spots along a creek in what is called the Happy Valley area of the island.

Deenagh River, Killarney

The Deenagh River flows through beautifully forested parts of Killarney National Park in the city of Killarney. Because of the fast current and stony bottom, I took a sample in a calmer spot along the shore. Horse-drawn carriages in the park give rides to tourists along the trails and across the bridge.

Abhainn Bhaile na Rátha River, Dunquin

Dunquin is a small town on the spectacular Dingle Peninsula (where the 1970s movie Ryan’s Daughter was filmed). The Abhainn Bhaile na Rátha River flows through farmlands from around Dunquin to the sea at Dingle Bay. Because of the current, I again obtained a sample in a calmer spot not far from the stream mouth.

Washing Pool, Adare

Adare is a town just southwest of Limerick where a small tributary of the Maigue River flows through. The Main Street bridge crosses it at a place called the Washing Pool. This is where many years ago, women of the area would gather to do their washing. Animals used it as a watering hole. While drawing a specimen, small crustaceans (that likely ate diatoms) darted around and tried to get into my sample.

Images: A picturesque walled length of the river with an access point, a diatom.

Natural Capital: its time has come!

At the recent World Forum on Natural Capital in Edinburgh, Scotland I noticed a change in clothing. The concept of “Natural Capital” has been around for decades. What has changed is who is paying attention now. There were far more suits than at any other nature conservation conference I have attended.

View of Edinburgh Castle.

Edinburgh was the setting for an international conference about “natural capital” attended by museum President and CEO Meg Beckel. Image: Meg Beckel © Canadian Museum of Nature.

Briefly, Natural Capital can be defined as the world’s stocks of natural assets, which include geology, soil, air, water and all living things. It is from these assets that humans derive a wide range of services, often called ecosystem services, which make human life possible.

The language of natural capital is attracting a new crowd of people who are key to the future of our natural world. There are the usual suspects from the fields of nature conservation, natural science and government policy. But beyond them, we now see, and are hearing from, industry leaders, financial sector leaders and accounting professionals.

A crowd of conference delegates standing around and talking in a large hall.

The forum featured speakers, perspectives and case studies that led most of us to believe that the concept and application of Natural Capital in government and industry is real…and is taking off.

But it was an announcement at the forum that grabbed my interest, as it highlighted where natural history museums could play a role. The news was that consultations would be launched on a Natural Capital Protocol.

The protocol’s overall vision is to transform the way business operates through understanding and incorporating their impacts and dependencies on natural capital. It is anticipated that the resulting framework would be the starting point to inform future common standards of practice.

Five people sit on a stage while talking at the conference.

The protocol does not yet address one important source of data and knowledge about our natural world—natural history collections and the information derived from those collections. These could provide valid current and historical records to do an inventory and put a value on natural assets.

I mentioned this to a number of the natural capital researchers and they simply had not considered collections and associated research as sources of data. I see a definite call to action for the leaders of natural history museums and I plan to spread the word and get us engaged in this consultation phase of the Natural Capital Protocol. This blog is a first step!

I encourage people to share the news about the Forum, the Natural Capital Coalition and the Natural Capital Protocol. I was so inspired that I visited colleagues at the National Museum of Scotland and stirred them into action! I think natural history museums have a vital role to play, providing another lens on nature to help inspire understanding and respect for a better natural future.

Snapshots of (Natural) History

The million-some-odd pressed plant specimens in the National Herbarium of Canada are full of little notes and bit of intriguing information; oftentimes these are the tips of icebergs that can lead on some pretty interesting tangents. Every sheet is one small part of a larger, richer story.

Recently, while locating specimens from the Coppermine River (we’re examining all the plants from this region of Nunavut, including those from our recent fieldwork, for a new floristic paper), I came across a herbarium sheet that caught my attention.

This sheet, a very nicely pressed Arctic lousewort (Pedicularis langsdorffii subspecies arctica), had a neat, handwritten annotation written under the equally neat and tidy script of the handwritten herbarium label.

The note, “Museum slide no. 203”, got me wondering: Could that mean our museum? Do we have an over-50-year-old slide of this species somewhere? So I sent off a quick email to our always helpful archives staff, and not 20 minutes later they had something to show me.

Raymond Wood, the collector named on the plant specimens—and, as it turns out, a great enthusiast of photography—was a lawyer whose passion for Arctic plants was stoked only after visiting our herbarium and learning about them from the Dominion Botanist at the time, the museum’s own A. Erling Porsild. (Read Wood’s obituary in PDF).

Along with his wife Mildred, Raymond traveled across the Arctic photographing many different species. Mildred, apparently the botanist of the duo, carefully pressed and preserved these specimens so that they could serve as vouchers for the photos in our collection; each of their 775 photographed plants was pressed and added to the herbarium.

We still photograph many of the plant species that our teams collect in the Arctic each year, though now we’re more concerned with high-capacity SD cards and server space than rolls of film and slide-storage trays. These photos, new and old, serve to illustrate field guides, websites and publications, and to capture the imagination of plant lovers—like they did with Raymond and Mildred.

Just like with our plants, we never throw out old slides because you never know when they could come in handy. I’m sure that Mildred and Raymond would be thrilled that their old photos keep finding new life.

November in West Virginia: Inspiring the Next Generation.

Nature Near Everyone: A Shared Priority! That snappy slogan, and the projects it describes, came about from a creative conference I was privileged to attend this November So, let me share with you what happens when 150 people meet with the goal of inspiring a new generation to engage with nature.

The idea for the conference, held in West Virginia, emerged from the 2012 World Congress of the International Union for Conservation of Nature (IUCN). There, CEO’s of the world’s parks met to discuss the critical need to inspire a new generation to visit parks and connect with nature. This theme continued at the World Parks Congress in 2014, where there was a commitment to include a program stream about it at the 2016 IUCN World Conservation Congress in Hawaii.

The gathering in West Virginia was the North American summit, designed to prepare ideas for the 2016 congress. Over two days, facilitated group discussions and inspiring speakers resulted in 15 collaborative initiatives to take to Hawaii for further engagement with the global community.

Let me share one initiative that our team crafted. It is inspired by a group vision that “nature be accessible everywhere to everyone”. We determined that a step toward that vision would be to help people find nature that is near to where they live. A young member of our group suggested we simply promote the use of a digital tool that already exists and is free. It’s found at the website called “walkscore.com”.

We all used it to find nature areas near our own homes (I of course checked out my neighbourhood in Ottawa!). The application works in Canada, the United States and Mexico. It also lists parks and outdoor places. What a tool!

So, from this group brainstorm, an initiative to encourage individuals and organizations to promote walkscore.com was born! We called it “Nature : Just a Click and Steps Away”. We then merged our initiative with three others that looked at community ownership of natural spaces, at community-designed nature spaces and at multi-levels of government prioritizing natural spaces.

Getting youth engaged with nature was the goal of the summit, Inspiring the Next Generation. Image: istock © kirin_photo

What evolved was an overarching initiative titled: “Nature Near Everyone: A Shared Priority”. The subtext: Make it, Own it, Find it, Share it.

Of course, there were other groups that brainstormed other equally engaging projects. One proposed an international summit with youth and for youth. (There were numerous millennials at our summit but only one was under 18). Another proposal was to launch a global Nature Corps of young people interning in nature as part of their high school experience.

As you can tell, there were many ideas to make nature relevant again to young people. Some of these ideas can be acted on now and others will take time, talent and resources to advance. I look forward to seeing what comes forward at the IUCN Hawaii congress and beyond.

My Irish Diatom Adventure (Part 1)

Part 1: Finding Samples

Last September, I travelled as a tourist for two weeks with my brother Russell in Ireland, visiting both the beautiful Republic of Ireland and Northern Ireland.

As a volunteer since 2013 for the Canadian Museum of Nature, working for Paul Hamilton with freshwater diatoms, I felt this trip was also an opportunity to collect Irish diatom samples from rivers, lakes, streams and ponds for the museum. I was successful, obtaining 21 samples from around the island.

Although we were on an excellent bus tour, getting at freshwater samples was a bit of a challenge (unlike travelling by car at your own pace): I was limited to towns and cities on the itinerary, which were mainly along the coast. Our periodic stops were for an hour or so.

Rivers flowing through coastal towns tended to be tidal (with salt water), so it was necessary to find fresh water flowing from upstream. Also, rivers through cities and towns were often walled off with little or no public access; in rural areas, they were sometimes fenced off. Some were fast flowing, or the water was too deep. Nevertheless, I still had many good opportunities to find accessible lakes, streams and ponds on the tour.

To obtain and process a sample, mud from the bottom—which contains diatoms—was collected using a turkey baster and put into small bottles. Photos of the collection area were taken and a local tourist map obtained to mark the exact location of the sample.

Their study helps environmental scientists learn how humans can affect ecosystem health and biodiversity, whether through local urbanization or global climate change.

Back at the hotel, samples were filtered using a funnel and special filter paper and then dried overnight. Once dry, the samples were sealed in labelled baggies for the trip home. Latitude and longitude were determined later using Google Maps, which worked well.

Paul and I are looking forward to processing and photographing more of these Irish samples. They will provide the museum with a taste for what Irish diatoms are like and what further research may be done.

The Arctic Flora of Tamriel: Botany in Video Games

Crouched down on the hilly tundra outside Whiterun, the Dragonborn spots their quarry. No, not a dragon, nor a lumbering mammoth, but a patch of tundra cotton, swaying gently in the breeze coming down the Throat of the World.

Plants have been antagonists, useful items and scenery in video games ever since Mario jumped over his first piranha plant. As a big RPG (role-playing game) fan, more than once I’ve been caught unaware (virtually) while inspecting a digital ecosystem.

Given the recent release of Fallout 4, a highly anticipated RPG, I thought it would be fun to look at the real-world inspirations behind some of these virtual plants.

Although the leaf shape indicates that tundra cotton may be a dicot (having netted leaf veins) rather than a monocot like real-world cottongrass (parallel leaf veins), the cottongrass—an iconic tundra plant—clearly inspired Elder Scrolls‘ tundra cotton.

Skyrim takes place in the titular northern province of Tamriel, the setting for the Elder Scrolls series. Previous Elder Scrolls games have featured the fungi-dominated island of Morrowind, or the temperate, mixed-hardwood climes of Cyrodiil. In both cases, the plants in the environment help to set the mood of the game by telegraphing to players a sense of fantasy and familiarity respectively.

Skyrim is no exception—this alpine and Arctic realm features many plants that are inspired by those found in our real-world polar regions, thus adding to the realism and helping transport the player on an Arctic adventure.

There are striking similarities between the Castilleja species, which are found in Canada’s Arctic and alpine regions, and Skyrim‘s mountain flower. For instance, flower and bract colours are important characters in distinguishing both the real and fictional species from each other.

Some Skyrim plant species are direct copies of their real-world counterparts, like juniper (in-game juniper) and wheat. Some, like gleamblossoms, are completely fictional. Others are re-named versions of terrestrial species; for instance, you or I may recognize snowberries as holly.

Skyrim‘s mountain flowers—very, very similar to real-world Castilleja species—are easily distinguished based on flower colour. And in the game’s universe, they are additionally differentiated by chemotaxonomy: the differences in the health effects that they impart on the player indicate that different chemicals (secondary metabolites) are produced by each species.

Just like all real-world vascular-plant species, the virtual plants of Tamriel have been placed in different environments associated with that species, which enhances the realism of the virtual ecosystem. Aspiring e-botanists will have to search high and low to find them all; don’t worry, just like with real-life floras, high-quality “dot maps” of where they are located also exist for the Elder Scrolls series.

In Fallout: New Vegas, as with the other members of the Fallout series, the player navigates the wasteland of a parallel, post-apocalyptic Earth, surviving on their wits, resourcefulness and a steady diet of (mostly) irradiated plants. Many of these plants, such as white horsenettle (Solanum elaeagnifolium; in-game plant) and barrel cactus (Ferocactus sp.; in-game plant) are real species.

Fallout: New Vegas takes place in a parallel world that is based on our own. As such, two legumes that are common in the southwestern United States, pinto beans (Phaseolus vulgaris) and honey locust (Prosopis glandulosa), are re-created with a high level of accuracy.

Plants populate many, many types of video games, sometimes as antagonists. While I’ve yet to see an ambulatory cactus on my field excursions, some fungal species actually do control plant hosts—not unlike the ancient Thorian in Mass Effect.

Whether friend or foe, plants will definitely find themselves in video games for a long time to come, healing player characters, being a thorn on your parties’ side, or simply providing a richer gaming experience.

Though they may draw on real-world inspirations, many plants in video games are completely fictional (and antagonistic), including Plants versus Zombie‘s peashooter, Final Fantasy‘s cactuar, Super Mario‘s piranha plant, and Mass Effect‘s Thorian.
