The decade that was (2010-19) and the decade to come (2020-29): Science culture in Canada (4 of 5)

Citizen science

Astronomy and bird watching (ornithology) are probably the only two scientific endeavours that have consistently engaged nonexperts/amateurs/citizen scientists right from the earliest days through the 21st century. Medical research, physics, chemistry, and others have, until recently and despite their origins in ‘amateur’ (or citizen) science, become the exclusive domain of professional experts.

This situation seems to be changing both here in Canada and elsewhere. One of the earliest postings about citizen science on this blog was in 2010 and, one of the most amusing to me personally, was this March 21, 2013 posting titled: Comparing techniques, citizen science to expert science. It’s about a study by scientists at the University of East Anglia (UK) comparing data collection by citizen scientists with experts. In this particular project where undersea data was being collected and people with diving skills needed, the citizen scientists did a better job than the expert scientists of collecting data. (I’m not trying to suggest that experts can be replaced by amateurs but do suggest that there are advantages to working together.)

*As for the Canadian science (from a June 15, 2018 Innovation, Science and Economic Development Canada news release),*

Take a look at your car. The bus you take to work. The smart phone you tap on during your commute. They all have one thing in common: science. Science is all around us. It shapes the way we live, the meals we grab on the go and the commute that takes us to school and work.
That is why the Government of Canada is encouraging young Canadians’ interest in science. Research and innovation lead to breakthroughs in agriculture, transit, medicine, green technology and service delivery, improving the quality of life for all Canadians. The outcomes of research also create jobs, strengthen the economy and support a growing middle class.
The Honourable Kirsty Duncan, Minister of Science and Minister of Sport and Persons with Disabilities, carried that message to an audience of young students during her first citizen science Google Hangout today. The Hangout, run by Exploring by the Seat of Your Pants, a not-for-profit organization, featured frog exhibits from the Toronto Zoo and a demonstration of the FrogWatch citizen science project by Dr. Nancy Kingsbury of Environment and Climate Change Canada. Toronto Zoo frog expert Katherine Wright joined Minister Duncan at the zoo to share information about frogs that are local to Ontario.
Minister Duncan, Dr. Kingsbury and Ms. Wright then engaged with elementary school children across Canada in a live Q&A session about the frogs in their own backyards. The Minister highlighted the importance of getting young Canadians interested in science fields and talked about ways they can take part in citizen science projects in their communities. Citizen scientists can share their observations on social media using the hashtag #ScienceAroundMe.
Quotes
“Science is for everyone, and it is important that we encourage today’s youth to be curious. Young Canadians who engage in citizen science today will become the highly skilled workers—engineers, scientists, mathematicians, technology experts and entrepreneurs—of tomorrow. Through citizen science, children can nurture an interest in the natural world. These young people will then go on to discover, to innovate and to find solutions that will help us build a better Canada.”
– The Honourable Kirsty Duncan, Minister of Science and Minister of Sport and Persons with Disabilities
“The Toronto Zoo is proud to participate in and encourage citizen science programs, such as FrogWatch, within the community. The Toronto Zoo’s Adopt-A-Pond Wetland Conservation Programme works to engage citizen scientists and deliver impactful conservation-focused research, restoration and outreach that highlight the importance of saving Canada’s sensitive wetland species and their habitats.”
– Robin Hale, Interim Chief Executive Officer, Toronto Zoo
Quick facts
NatureWatch, of which FrogWatch is a component, is a community program that engages all Canadians in collecting scientific information on nature to understand our changing environment.
Exploring by the Seat of Your Pants aims to inspire the next generation of scientists, explorers and conservationists by bringing science, exploration, adventure and conservation into classrooms through virtual field trips run by programs like Google Hangout.
The Government of Canada’s Citizen Science Portal is a one-stop shop for science in the community. It showcases science programs, including NatureWatch programs, across the country.
Associated links

The portal is not nearly as Ontario-centric as the projects mentioned in the news release (in case you were wondering).

Aside: In part 2 of this series, Jesse Hildebrand, founder of Science Literacy Week was mentioned as also being the founder of Exploring by the Seat of Your Pants.

Going to the birds

While bird watching and ornithological studies are not new to the Canadian science culture scene, there were some interesting developments in the 2010-19 period.

Canadian Geographic (magazine) sponsored a contest in 2015, the National Bird Project, where almost 50,000 people submitted suggestions for a national bird. Voting online ensued and on August 31, 2016 popular voting was closed. Five birds attracted the top votes and in September 2016, the Royal Canadian Geographical Society put together an expert panel to debate and decide which would be Canada’s national bird. The choice was announced in November 2016 (Canadian Geographic National Bird Project).

From the National Bird Project webpage,

The gray jay (Perisoreus canadensis in Latin, Mésangeai du Canada in French) lives in all 13 provinces and territories — the friendly spirit in Canada’s wild northern boreal and mountain forests. It remains in Canada year-round, is neither hunted nor endangered, and from the Atlantic provinces to the West is an indicator of the health of the boreal and mountain forests and climate change, inspiring a conservation philosophy for all kinds of northern land uses. The gray jay has long been important to Indigenous Peoples, and will draw all Canadians to their national and provincial/territorial parks, yet unlike the loon and snowy owl, it is not already a provincial or territorial bird.

I found a more fulsome description on the What is the National Bird of Canada? webpage on the World Atlas website,

…
Gray jay is a passerine bird belonging to the family Corvidae. It is mostly found in the boreal forest of North America. The bird is fairly large and has pale gray underparts and dark grey upperpart. Gray jay is a friendly bird and often approach human for food. It is also popularly known as the camp robber, whisky jack, and venison-hawk. Gray jay is listed as Least Concern by the IUCN [International Union for Conservation of Nature]. However, the anthropogenic climate change in the southern range may adversely affect its population. In some Fist Nation cultures, the bird is associated with mythological figures including Wisakedjak who was anglicized to Whiskyjack.
…
For approximately 200 years, the gray jay was known as “Canadian Jay” to the English speakers. The bird was renamed the “gray jay” in 1957 by the American Ornithologists’ Union. However, scientifically the bird is referred to as Perisoreus Canadensis. The bird is found in almost all the provinces of territories of Canada. the preferred habitat for the species is Canada’s boreal and mountain forests. Gray jay is also one of the smartest birds in the world and has almost the same body-to-brain ratio as human beings.

Canadian Georgraphic offers more depth (and a map) in a November 16, 2016 article, by Nick Walker, titled, Canada, meet your national bird (Note: Links have been removed),

With 450 species in the country to choose from, Canadian Geographic’s decision was made neither lightly nor quickly.
This national debate has been running since January 2015, in fact. But after weighing the opinions and preferences of tens of thousands of Canadians, as well as the expertise of our National Conservation Partners at Bird Studies Canada and other ornithologists and conservationists, as well as cultural experts and Indigenous Peoples, that list was narrowed to five birds. And one finalist best met all reasonable criteria.

We give you the gray jay. …
…
Not only has the gray jay never been recorded outside of North America, the vast majority of its range is in Canada, with only a small percentage crossing into Alaska and the western mountains of the United States. The species’ preferred habitat is Canada’s boreal and mountain forests — ecozones that stretch from coast to coast and into the North, blanketing nearly two-thirds of the country.
…
Like the Canadian flag when it was selected in 1965, the gray jay is fresh and new and fitting. To quote David Bird, ornithologist and professor emeritus of wildlife biology at Montreal’s McGill University, we cannot think of a more Canadian bird.

Three sets of bird stamps were issued by Canada Post from 2016-2018 saluting “Canada’s avian citizens.” Here’s more from a July 12, 2016 Birds of Canada blog post on the Canada Post website announcing the first series of bird stamps,

Hatched by designer Kosta Tsetsekas and illustrator Keith Martin, these stamps are the first in a three-year series celebrating Canada’s avian citizens. Our first flock includes five official birds: the Atlantic puffin (Newfoundland and Labrador), the great horned owl (Alberta), the common raven (Yukon), the rock ptarmigan (Nunavut) and the sharp-tailed grouse (Saskatchewan).
…

An August 1, 2017 Canada Post blog post announced that year’s bird stamps and, finally, an August 20, 2018 Canada Post blog post announced the finale release. The 2018 series was released in time to celebrate the 27th International Ornithological Congress held in Vancouver (from the Vancouver Convention Centre congress webpage),

On behalf of the International Ornithologists’ Union, Vancouver is delighted to welcome ornithologists from around the world to the 27th International Ornithological Congress (IOCongress2018)! Considered the oldest and most prestigious of meetings for bird scientists, the Congress occurs every four years since first being held in Vienna, Austria, in 1884.
Canada has hosted only once previously, Ottawa in 1986, and Vancouver will be the first time the Congress has been on the Pacific Coast of the Americas. The Congress has broad national endorsement, including from the City of Vancouver, the province of British Columbia, Environment Canada, Simon Fraser University, Artists for Conservation, Tourism Vancouver plus an array of scientific societies and conservation organizations.

The convention centre’s webpage features an impressive list of events which were open to the public,

Stars of the Bird World Presentation (August 19): Dr. Rob Butler, chair of the Vancouver International Bird Festival, presents Flyways to Culture: How birds give rise to a cultural awakening, at look at how the growing interest in birds in particular and nature in general, is a foundation for a new Nature Culture in which nature becomes embedded into a west coast culture. 8:30-10 a.m. at the Vancouver Convention Centre. Admission by donation ($10 suggested).
Festival Opening Ceremony – Parade of Birds and a fanfare by Vancouver Symphony Brass Quintet (August 20): The festival begins with a Parade of Birds and a fanfare by the Vancouver Symphony Brass Quintet. The fanfare “Gathering Flock” was composed by Frederick Schipizky. 3:20 p.m. to 5:15 p.m. at the Vancouver Convention Centre.
Artists for Conservation Show (August 22): Artists for Conservation is the official visual arts partner for the festival and congress, showcasing some of the world’s best nature art through its annual juried exhibit, a collaborative mural, artist demo and lecture series and an artist booth expo. Official opening 6-10 p.m. at the Vancouver Convention Centre.

Migration Songs – Poetry and Ornithology (August 23): Migration Songs brings together 11 contemporary poets to consider an array of bird species. Each poet was put in conversation with a particular ornithologist or scientist to consider their chosen species collaboratively. The poets involved include well-known west-coast authors, amongst them Governor General’s Award and Griffin Poetry Prize winners. A short book of these collaborations, Migration Songs, with cover art by poet, painter, and weaver Annie Ross, will be available. 6 p.m. at the Vancouver Convention Centre.
Unveiling of the Silent Skies Mural (August 23): A signature event of the week-long Artists for Conservation show is the unveiling of the Silent Skies mural made up of illustrations of the endangered birds of the world — 678 pieces, each depicting a different endangered bird, will make up the 100-foot-long installation that will form the artistic centrepiece for the 8th annual Artists for Conservation Festival, the 27th International Ornithological Congress and Vancouver International Bird Festival. The unveiling takes place at 6:30 p.m. at the Vancouver Convention Centre.
Stewardship Roundtable 2018 (August 24): A forum and showcase of innovative practices championed in B.C. province and beyond, presented by the Stewardship Centre for BC and Bird Studies Canada, in collaboration with the 27th International Ornithological Congress and Vancouver International Bird Festival. 8:30 a.m. until 9 p.m. at the Vancouver Convention Centre. For more information or to register, visit stewardshipcentrebc.ca/programs/wildife-species-risk/stewardship-roundtable.
Closing Ceremony (August 26): The closing ceremony will include remarks from officials and First Nations representatives, and a Heron Dance by the New Dance Centre from Saskatchewan. 5-6:30 p.m. at Vancouver Convention Centre.

I attended the opening ceremony where they announced the final set of stamps in the Birds of Canada series by introducing people who’d dressed for the parade as the birds in question.

The Canadian birding community has continued to create interesting new projects for science outreach. A December 19, 2019 posting by Natasha Barlow for Birds Canada (also known as Bird Studies Canada) announces a new interactive story map,

The Boreal Region is a massive expanse of forests, wetlands, and waterways covering much of the Northern Hemisphere. In Canada, this vast region stretches for 5000 kilometres from Newfoundland and Labrador through the country’s central regions and northwest to the Yukon.
Over 300 bird species regularly breed here, from tiny songbirds like kinglets and warblers to comparatively giant swans and cranes. The Boreal is home to literally billions of birds, and serves as the continent’s bird “nursery” since it is such an important breeding ground.
While extensive tracts of Canada’s northern Boreal still remain largely undisturbed from major industrial development, the human footprint is expanding and much of the southern Boreal is already being exploited for its resources.
Birds Canada, in partnership with the Nature Conservancy of Canada, has created an interactive story map that details the importance of the Boreal region for birds.

Climate change, ecology, and Indigenous knowledge (science)

There is more focus on climate change everywhere in the world and much of the latest energy and focus internationally can be traced to Swedish teenager, Greta Thunberg who turned 17 in January 2020. Her influence has galvanized a number of youth climate strikes in Canada and around the world.

There is a category of science fiction or speculative fiction known as Climate Fiction (cli-fi or clifi). Margaret Atwood (of course) has produced a trilogy in that subgenre of speculative fiction, from the Climate Fiction Wikipedia entry, Note: Links have been removed,

…
Margaret Atwood explored the subject in her dystopian trilogy Oryx and Crake (2003), The Year of the Flood (2009) and MaddAddam (2013).^[13] In Oryx and Crake Atwood presents a world where “social inequality, genetic technology and catastrophic climate change, has finally culminated in some apocalyptic event”.^[14] The novel’s protagonist, Jimmy, lives in a “world split between corporate compounds”, gated communities that have grown into city-states and pleeblands, which are “unsafe, populous and polluted” urban areas where the working classes live.^[15]
…

There is some other cli-fi literature by Canadians, notably an anthology of Canadian short stories edited by Bruce Meyer, from a March 9, 2018 review by Emilie Moorhouse published in Canada’s National Observer (review originally published in Prism magazine on March 8, 2018), Note: A link has been removed,

A woman waits in line to get her water ration. She hasn’t had a sip of water in nearly three days. Her mouth is parched; she stumbles as she waits her turn for over an hour in the hot sun. When she he finally gets to the iTap and inserts her card into the machine that controls the water flow, the light turns red and her card is rejected. Her water credits have run out.
This scenario from “The Way of Water” by Nina Munteanu is one of many contained in the recently published anthology of short stories, Cli-Fi: Canadian Tales of Climate Change. The seventeen stories in this book edited by Bruce Meyer examine how humankind might struggle with the potential devastation of climate change in the near or distant future. Soon after I finished reading the book, Cape Town—known in precolonial times as “the place where clouds gather”—announced that it was only a few months away from what it called “Day Zero,” the day the city would officially run out of water, making the similarities between fiction and reality more than unsettling. Munteanu’s story is set in a futuristic Canada that has been mined of all its water by thirsty corporations who have taken over control of the resource. Rain has not fallen on Canadian soil in years due to advances in geoengineering and weather manipulation preventing rain clouds from going anywhere north of the Canada-US border.
…

Indigenous knowledge (science)

The majority of Canada’s coastline is in the Arctic and climate change in that region is progressing at a disturbing pace. Weather, Climate Change, and Inuit Communities in the Western Canadian Arctic, a September 30, 2017 blog posting, by Dr. Laura Eerkes-Medrano at the University of Victoria (British Columbia) for Historical Climatology describes it this way (Note: A link has been removed),

Global climate change brings with it local weather that communities and cultures have difficulty anticipating. Unpredictable and socially impactful weather is having negative effects on the subsistence, cultural activities, and safety of indigenous peoples in Arctic communities. Since 2013, Professor David Atkinson and his team at the University of Victoria have been working with Inuvialuit communities in Tuktoyaktuk, Ulukhaktok, and Sachs Harbour. The main goal is to understand how impactful weather is affecting residents’ subsistence activities, particularly when they are on the water. The project involves site visits, interviews, and regular phone calls with residents.
Inuvialuit residents regularly observe the waves, winds, snow, and ice conditions that interfere with their hunting, fishing, camping, and other subsistence and cultural activities. In this project, communities identify specific weather events that impact their activities. These events are then linked to the broader atmospheric patterns that cause them. Summaries of the events will be provided to Environment Canada to hopefully assist with the forecasting process.
By taking this approach, the project links Western scientific knowledge and traditional knowledge to generate insights [emphasis mine] into how climate change is affecting Inuvialuit activities in the Canadian Arctic. An oversight committee has been established in each community to give direction to the project. This oversight committee includes representatives from each of the main community organizations, which ensures that the respective organizations provide direction to the project and advise on how to engage residents and communities.
…

Western science learning from and taking from traditional knowledge is not new. For example, many modern medicines are still derived from traditional remedies. Unfortunately, traditional practitioners have not benefited from sharing their knowledge.

It is to be hoped things are changing with projects like Atkinson’s and another one I mentioned in a December 2, 2019 posting featuring a discovery about ochre (a red dye used for rock art). The dye being examined was produced (in a manner that appears to be unique) in the Babine Lake region of British Columbia and the research may have applications for industrial use leading to economic benefits for the indigenous folks of that region. As important as the benefits, the science team worked closely with the indigenous communities in that area.

University in the Arctic

I was told several years ago that Canada is the only ‘arctic country’ that does not have a university in the high north. As of 2019 it seems the situation is changing, from a December 1, 2019 Global television news online item,

Canada will finally have its first Arctic university.
This past week [of December 1, 2019], the Yukon legislature passed a bill to make Yukon College a university. It will be an institution with an Indigenous flavour that will make it as unique as the region it is to serve.
“Everybody knows we’re moving toward something big and something special,” said Tom Ullyett, chairman of the board of governors.
The idea of a northern university has been kicked around since at least 2007 when a survey in all three territories found residents wanted more influence over Arctic research. Northern First Nations have been asking for one for 50 years.
…
Research is to centre on issues around environmental conservation and sustainable resource development. It will be conducted in a new, $26-million science building funded by Ottawa and currently being designed.
Indigenous content will be baked in.
“It’s about teaching with northern examples,” said Tosh Southwick, in charge of Indigenous engagement. “Every program will have a northern component.”
Science programs will have traditional knowledge embedded in them and talk about ravens and moose instead of, say, flamingos and giraffes. Anthropology classes will teach creation stories alongside archeological evidence.
…
The institution will report to Yukon’s 14 First Nations as well as to the territorial legislature. More than one-quarter of its current students are Indigenous.
…
“Our vision is to be that first northern university that focuses on Indigenous governance, that focuses on sustainable natural resources, that focuses on northern climate, and everything that flows from that.”
…

Climate adaptation and/or choices

While we have participated in a number of initiatives and projects concerned with climate change, I believe there is general agreement we should have done more. That said I would prefer to remain hopeful.

A January 23, 2020 Yukon College news release announces the appointment of a staff member to an Canadian federal government institute’s advisory committee,

A newly launched institute for climate policy research will have a Yukon connection. Brian Horton, Manager of Northern Climate ExChange at the Yukon Research Centre, has been named to the Canadian Institute for Climate Choices expert advisory panel for Climate Adaptation.
The Institute, launched Tuesday morning, aims to bring clarity to Canada’s climate policy choices. The Institute’s initial report, Charting our Course, describes the current climate landscape in Canada and provides recommendations for policy makers and governments seeking to implement more effective policy.
In order to remain grounded in issues of importance to Canadians, the Institute has appointed three Expert Advisory Panels (Adaptation, Mitigation and Clean Growth) to provide evidence-based research, analysis and engagement advice to support integrative policy decisions.
“It is exciting to have a role to play in this dynamic new network,” said Horton. “The climate is rapidly changing in the North and affecting our landscapes and lives daily. I look forward to contributing a Northern voice to this impactful pan-Canadian expert collaboration.”
At Yukon College, Horton’s research team focusses on applied research of climate impacts and adaptation in Yukon and Northwest Territories. Northern Climate ExChange works with communities, governments, and the private sector to answer questions about permafrost, hydrology, and social factors to facilitate adaptation to climate change.
…

By the way, the Canadian Institute for Climate Choices was launched on January 21, 2020 (news release),

January 21, 2020 | OTTAWA — Dozens of academics and policy experts today launched the Canadian Institute for Climate Choices, a new independent national research body. The Institute aims to bring clarity to the transformative challenges, opportunities and choices ahead for Canada as governments at all levels work to address climate change.

Experimental Lakes Area

This is a very special research effort originally funded and managed by the Canadian federal government. Rather controversially, Stephen Harper’s Conservative government defunded the research but that may not have been the tragedy many believed (from the Experimental Lakes Area Wikipedia entry),

IISD Experimental Lakes Area (IISD-ELA, known as ELA before 2014)^[1] is an internationally unique research station encompassing 58 formerly pristine freshwater lakes in Kenora District Ontario, Canada.^[2][3] Previously run by Fisheries and Oceans Canada, after being de-funded by the Canadian Federal Government, the facility is now managed and operated by the International Institute for Sustainable Development (IISD) and has a mandate to investigate the aquatic effects of a wide variety of stresses on lakes and their catchments. IISD-ELA uses the whole ecosystem approach and makes long-term, whole-lake investigations of freshwater focusing on eutrophication.^[4][5]
In an article^[2] published in AAAS’s well-known scientific journal Science, Eric Stokstad described ELA’s “extreme science”^[2] as the manipulation of whole lake ecosystem with ELA researchers collecting long-term records for climatology, hydrology, and limnology that address key issues in water management.^[4] The site has influenced public policy in water management in Canada, the USA, and around the world.^[2]
Minister of State for Science and Technology, Gary Goodyear, argued that “our government has been working hard to ensure that the Experimental Lakes Area facility is transferred to a non-governmental operator better suited to conducting the type of world-class research that can be undertaken at this facility” and that “[t]he federal government has been leading negotiations in order to secure an operator with an international track record.” On April 1, 2014, the International Institute for Sustainable Development announced that it had signed three agreements to ensure that it will be the long-term operator of the research facility and that the facility would henceforth be called IISD Experimental Lakes Area.^[6] Since taking over the facility, IISD has expanded the function of the site to include educational and outreach opportunities^[7] and a broader research portfolio.^[8]

Frogs: monitoring them, finding new species, and research about the golden ones in Panama

I have three frog-oriented items and while they’re not strictly speaking in my usual range of topics, given this blog’s name and the fact I haven’t posted a frog piece in quite a while, it seems this is a good moment to address that lack.

Monitoring frogs and amphibians at Trent University (Ontario, Canada)

From a March 23, 2015 Trent University news release,

With the decline of amphibian populations around the world, a team of researchers led by Trent University’s Dr. Dennis Murray will seek to establish environmental DNA (eDNA) monitoring of amphibian occupancy and aquatic ecosystem risk assessment with the help of a significant grant of over $596,000 from the Natural Sciences and Engineering Research Council of Canada (NSERC).

Awarded to Professor Murray, a Canada research chair in integrative wildlife conservation, bioinformatics, and ecological modelling and professor at Trent University along with colleagues Dr. Craig Brunetti of the Biology department, and Dr. Chris Kyle of the Forensic Science program, and partners at Laurentian University, University of Toronto, McGill University, Ontario Ministry of Natural Resources and Forestry and Environment Canada, the grant will support the development of tools that will promote a cleaner aquatic environment.

The project will use amphibian DNA found in natural breeding habitats to determine the presence and abundance of amphibians as well as their pathogens. This new technology capitalizes on Trent University’s expertise and infrastructure in the areas of wildlife DNA and water quality.

“We’re honoured to have received the grant to help us drive the project forward,” said Prof. Murray. “Our plan is to place Canada, and Trent, in a leadership position with respect to aquatic wildlife monitoring and amphibian conservation.”

Amphibian populations are declining worldwide, yet in Canada, amphibian numbers are not monitored closely, meaning changes in their distribution or abundance may be unnoticeable. Amphibian monitoring in Canada is conducted by citizen scientists who record frog breeding calls when visiting bodies of water during the spring. However, the lack of formalized amphibian surveys leaves Canada in a vulnerable position regarding the status of its diverse amphibian community.

Prof. Murray believes that the protocols developed from this project could revolutionize how amphibian populations are monitored in Canada and in turn lead to new insights regarding the population trends for several amphibian species across the country.

Here’s more about NSERC and Trent University from the news release,

About NSERC

NSERC is a federal agency that helps make Canada a country of discoverers and innovators. The agency supports almost 30,000 post-secondary students and postdoctoral fellows in their advanced studies. NSERC promotes discovery by funding approximately 12,000 professors every year and fosters innovation by encouraging over 2,400 Canadian companies to participate and invest in post-secondary research projects.

The NSERC Strategic Project Grants aim to increase research and training in areas that could strongly influence Canada’s economy, society or environment in the next 10 years in four target areas: environmental science and technologies; information and communications technologies; manufacturing; and natural resources and energy.

About Trent University

One of Canada’s top universities, Trent University was founded on the ideal of interactive learning that’s personal, purposeful and transformative. Consistently recognized nationally for leadership in teaching, research and student satisfaction, Trent attracts excellent students from across the country and around the world. Here, undergraduate and graduate students connect and collaborate with faculty, staff and their peers through diverse communities that span residential colleges, classrooms, disciplines, hands-on research, co-curricular and community-based activities. Across all disciplines, Trent brings critical, integrative thinking to life every day. As the University celebrates its 50th anniversary in 2014/15, Trent’s unique approach to personal development through supportive, collaborative community engagement is in more demand than ever. Students lead the way by co-creating experiences rooted in dialogue, diverse perspectives and collaboration. In a learning environment that builds life-long passion for inclusion, leadership and social change, Trent’s students, alumni, faculty and staff are engaged global citizens who are catalysts in developing sustainable solutions to complex issues. Trent’s Peterborough campus boasts award-winning architecture in a breathtaking natural setting on the banks of the Otonabee River, just 90 minutes from downtown Toronto, while Trent University Durham delivers a distinct mix of programming in the GTA.

Trent University’s expertise in water quality could be traced to its proximity to Canada’s Experimental Lakes Area (ELA), a much beleaguered research environment due to federal political imperatives. You can read more about the area and the politics in this Wikipedia entry. BTW, I am delighted to learn that it still exists under the auspices of the International Institute for Sustainable Development (IISD),

Taking this post into nanotechnology territory while mentioning the ELA, Trent University published a Dec. 8, 2014 news release about research into silver nanoparticles,

For several years, Trent University’s Dr. Chris Metcalfe and Dr. Maggie Xenopoulos have dedicated countless hours to the study of aquatic contaminants and the threat they pose to our environment.

Now, through the efforts of the International Institute for Sustainable Development (IISD), their research is reaching a wider audience thanks to a new video (Note: A link has been removed).

The video is one of a five-part series being released by the IISD that looks into environmental issues in Canada. The video entitled “Distilling Science at the Experimental Lakes Area: Nanosilver” and featuring Professors Metcalfe and Xenopoulos profiles their research around nanomaterials at the Experimental Lakes Area.

Prof. Xenopolous’ involvement in the project falls in line with other environmental issues she has tackled. In the past, her research has examined how human activities – including climate change, eutrophication and land use – affect ecosystem structure and function in lakes and rivers. She has also taken an interest in how land use affects the material exported and processed in aquatic ecosystems.

Prof. Metcalfe’s ongoing research on the fate and distribution of pharmaceutical and personal care products in the environment has generated considerable attention both nationally and internationally.

Together, their research into nanomaterials is getting some attention. Nanomaterials are submicroscopic particles whose physical and chemical properties make them useful for a variety of everyday applications. They can be found in certain pieces of clothing, home appliances, paint, and kitchenware. Initial laboratory research conducted at Trent University showed that nanosilver could strongly affect aquatic organisms at the bottom of the food chain, such as bacteria, algae and zooplankton.

To further examine these effects in a real ecosystem, a team of researchers from Trent University, Fisheries and Oceans Canada and Environment Canada has been conducting studies at undisclosed lakes in northwestern Ontario. The Lake Ecosystem Nanosilver (LENS) project has been monitoring changes in the lakes’ ecosystem that occur after the addition of nanosilver.

“In our particular case, we will be able to study and understand the effects of only nanosilver because that is the only variable that is going to change,” says Prof. Xenopoulos. “It’s really the only place in the world where we can do that.”

The knowledge gained from the study will help policy-makers make decisions about whether nanomaterials can be a threat to aquatic ecosystems and whether regulatory action is required to control their release into the environment.

Here’s more about the shapeshifting and how the scientists figured out what the frogs were doing (from a March 23, 2015 Case Western Research University news release on EurekAlert; Note: A link has been removed),

A frog in Ecuador’s western Andean cloud forest changes skin texture in minutes, appearing to mimic the texture it sits on.

Originally discovered by a Case Western Reserve University PhD student and her husband, a projects manager at Cleveland Metroparks’ Natural Resources Division, the amphibian is believed to be the first known to have this shape-shifting capability.

But the new species, called Pristimantis mutabilis, or mutable rainfrog, has company. Colleagues working with the couple recently found that a known relative of the frog shares the same texture-changing quality–but it was never reported before.

The frogs are found at Reserva Las Gralarias, a nature reserve originally created to protect endangered birds in the Parish of Mindo, in north-central Ecuador.

The researchers, Katherine and Tim Krynak, and colleagues from Universidad Indoamérica and Tropical Herping (Ecuador) co-authored a manuscript describing the new animal and skin texture plasticity in the Zoological Journal of the Linnean Society this week. They believe their findings have broad implications for how species are and have been identified. The process may now require photographs and longer observations in the field to ensure the one species is not mistakenly perceived as two because at least two species of rain frogs can change their appearance.

Katherine Krynak believes the ability to change skin texture to reflect its surroundings may enable P. mutabilis to help camouflage itself from birds and other predators.

The Krynaks originally spotted the small, spiny frog, nearly the width of a marble, sitting on a moss-covered leaf about a yard off the ground on a misty July night in 2009. The Krynaks had never seen this animal before, though Tim had surveyed animals on annual trips to Las Gralarias since 2001, and Katherine since 2005.

They captured the little frog and tucked it into a cup with a lid before resuming their nightly search for wildlife. They nicknamed it “punk rocker” because of the thorn-like spines covering its body.

The next day, Katherine Krynak pulled the frog from the cup and set it on a smooth white sheet of plastic for Tim to photograph. It wasn’t “punk “–it was smooth-skinned. They assumed that, much to her dismay, she must have picked up the wrong frog.

“I then put the frog back in the cup and added some moss,” she said. “The spines came back… we simply couldn’t believe our eyes, our frog changed skin texture!

“I put the frog back on the smooth white background. Its skin became smooth.”

“The spines and coloration help them blend into mossy habitats, making it hard for us to see them,” she said. “But whether the texture really helps them elude predators still needs to be tested.”

During the next three years, a team of fellow biologists studied the frogs. They found the animals shift skin texture in a little more than three minutes.

Juan M. Guayasamin, from Universidad Tecnológica Indoamérica, Ecuador, the manuscript’s first author, performed morphological and genetic analyses showing that P. mutabilis was a unique and undescribed species. Carl R. Hutter, from the University of Kansas, studied the frog’s calls, finding three songs the species uses, which differentiate them from relatives. The fifth author of the paper, Jamie Culebras, assisted with fieldwork and was able to locate a second population of the species. Culebras is a member of Tropical Herping, an organization committed to discovering, and studying reptiles and amphibians.

Guayasamin and Hutter discovered that Prismantis sobetes, a relative with similar markings but about twice the size of P. mutabilis, has the same trait when they placed a spiny specimen on a sheet and watched its skin turn smooth. P. sobetes is the only relative that has been tested so far.

Because the appearance of animals has long been one of the keys to identifying them as a certain species, the researchers believe their find challenges the system, particularly for species identified by one or just a few preserved specimens. With those, there was and is no way to know if the appearance is changeable.

The Krynaks, who helped form Las Gralarias Foundation to support the conservation efforts of the reserve, plan to return to continue surveying for mutable rain frogs and to work with fellow researchers to further document their behaviors, lifecycle and texture shifting, and estimate their population, all in effort to improve our knowledge and subsequent ability to conserve this paradigm shifting species.

Further, they hope to discern whether more relatives have the ability to shift skin texture and if that trait comes from a common ancestor. If P. mutabilis and P. sobetes are the only species within this branch of Pristimantis frogs to have this capability, they hope to learn whether they retained it from an ancestor while relatives did not, or whether the trait evolved independently in each species.

Among many of the pressures on frog populations, there’s a lethal fungus which has affected some 200 species of frogs. A March 23, 2015 news item on ScienceDaily describes some recent research into the bacterial communities present on frog skin,

A team of scientists including Virginia Tech researchers is one step closer to understanding how bacteria on a frog’s skin affects its likelihood of contracting disease.

A frog-killing fungus known as Batrachochytrium dendrobatidis, or Bd, has already led to the decline of more than 200 amphibian species including the now extinct-in-the-wild Panamanian golden frog.

In a recent study, the research team attempted to apply beneficial bacteria found on the skin of various Bd-resistant wild Panamanian frog species to Panamanian golden frogs in captivity, to see if this would stimulate a defense against the disease.

A March 23, 2015 Virginia Tech University news release on EurekAlert, which originated the news item, provides a twist and a turn in the story (Note: Links have been removed),

They found that while the treatment with beneficial bacteria was not successful due to its inability to stick to the skin, there were some frogs that survived exposure to the fungus.

These survivors actually had unique bacterial communities on their skin before the experiments started.

…

The next step is to explore these new bacterial communities.

“We were disappointed that the treatment didn’t work, but glad to have discovered new information about the relationship between these symbiotic microbial communities and amphibian disease resistance,” said Lisa Belden, an associate professor of biological sciences in the College of Science, a Fralin Life Science Institute affiliate, and a faculty member with the new Global Change Center at Virginia Tech. “Every bit of information gets us closer to getting these frogs back into nature.”

Studying the microbial communities of Panamanian golden frogs was the dissertation focus of Belden’s former graduate student Matthew Becker, who graduated with a Ph.D. in biological sciences from Virginia Tech in 2014 and is now a fellow at the Smithsonian Conservation Biology Institute.

“Anything that can help us predict resistance to this disease is very useful because the ultimate goal of this research is to establish healthy populations of golden frogs in their native habitat,” Becker told Smithsonian Science News. “I think identifying alternative probiotic treatment methods that optimize dosages and exposure times will be key for moving forward with the use of probiotics to mitigate chytridiomycosis.”
