My Books Are Feeding Meta’s AI Brat

 On March 20, 2025, in an article in The Atlantic entitled “The Unbelievable Scale of AI’s Pirated-Books Problem”, Alex Reisner disclosed how META pirated millions of books and research papers to train their flagship AI model Llama 3 to be competitive with products like ChatGPT. Reasons for this illegal action is simply time; asking permission and licensing takes too much time and is too expensive.

On the same day, The Atlantic provided a link to LibGen (the pirated-books database that Meta used to train its AI) so authors could search its collection of millions of illegally captured books and scientific papers. I went there and searched my name for my novels, non-fiction books and scientific papers and discovered several of my works in their AI training collection.

Two of my many scientific papers appeared in LibGen under my scientific author name Norina Munteanu. The first scholarly article came from my post grad work at the University of Victoria on the effects of mine tailing effluent on an oligotrophic lake, published in 1984 in Environmental Pollution Series A, Ecological and Biological Volume 33, Issue 1. The second article on the effect of current on settling periphyton came from my M.Sc. ecology research published in 1981 in Hydrobiologia, Volume #78.

.

.

Three of my thirteen novels appeared in LibGen under my fiction author name Nina Munteanu. I found it interesting how their bots captured a good range of my works. These included two of my earliest works. Collision with Paradise (2005) is an ecological science fiction adventure and work of erotica; Darwin’s Paradox (2007) is a science fiction medical-eco thriller that features the domination of society by an intelligent AI community. The bots also found my latest novel, A Diary in the Age of Water (2020), a climate thriller and work of eco-fiction that follows four generations of women and their relationship to water.

Each of these works has been highly successful in sales and has received a fair bit of attention and recognition.

When Genevieve Dubois, Zeta Corp’s hot shot starship pilot, accepts a research mission aboard AI ship ZAC to the mysterious planet Eos, she not only collides with her guilty past but with her own ultimate fantasy. On a yearning quest for paradise, Genevieve thinks she’s found it in Eos and its people; only to discover that she has brought the seed of destruction that will destroy this verdant planet.

Recognition: Gaylactic Spectrum Award (nominee)

“Collision with Paradise is ideal for readers who enjoy dark, introspective science fiction that explores complex moral dilemmas and psychological depth within a lush mythologically-rich setting.”—The Storygraph

.

A devastating disease. A world on the brink of violent change. And one woman who can save it or destroy it all. Julie Crane must confront the will of the ambitious virus lurking inside her to fulfill her final destiny as Darwin’s Paradox, the key to the evolution of an entire civilization. Darwin’s Paradox is a novel about a woman s fierce love and her courageous journey toward forgiveness, trust, and letting go to the tide of her heart.

Recognition: Readers Choice Award (Midwest Book Review); Readers Choice (Delta Optimist); Aurora Award (nominee)

“Darwin’s Paradox is a thrill ride that makes you think and tugs the heart.”—Robert J. Sawyer, Hugo and Nebula Award winning author of Rollback

.

This gritty memoir describes a near-future Toronto in the grips of severe water scarcity during a time when China owns the USA and the USA owns Canada. A Diary in the Age of Water follows the climate-induced journey of Earth and humanity through four generations of women, each with a unique relationship to water. The diary spans a twenty-year period in the mid-twenty-first century of 33-year-old Lynna, a single mother and limnologist of international water utility CanadaCorp, and who witnesses disturbing events that she doesn’t realize will soon lead to humanity’s demise. 

Recognition: 2020 Foreword Indies Book of the Year Award (Bronze); 2020 Titan Literary Book Award (Silver); 2021 International Book Award (Finalist).

“If you believe Canada’s water will remain free forever (or that it’s truly free now) Munteanu asks you to think again. Readers have called ‘A Diary in the Age of Water’ “terrifying,” “engrossing,” and “literary.” We call it wisdom.”— LIISBETH

.

The April 3, 2025 article by Ella Creamer of The Guardian noted that a US court filing alleged that Meta CEO Mark Zuckerberg approved the company’s use of the notorious “shadow library”, LibGen, which contains more than 7.5 million books and 81 million research papers. According to Toby Walsh, leading AI researcher at the University of New South Wales: “As far as we know, there was an explicit instruction from Mark Zuckerberg to ignore copyright.”

This begs the question of the role and power of copyright law.

“Copyright law is not complicated at all,” said Richard Osman, author of The Thursday Murder Club series. “If you want to use an author’s work you need to ask for permission. If you use it without permission you’re breaking the law. It’s so simple.”

If it’s so simple then why is Meta and others getting away with it? For its defence, the tech giant is claiming “fair use”, relying on this term permitting the limited use of copyrighted material without the owner’s permission (my italics).

It would seem that just as Trump trumped the presidency, Zuckerberg and his AI minion bots have trumped the copyright law—by flagrantly violating it and getting away with it—so far (on both counts).

The actions of Meta were characterized by Society of Authors chair Vanessa Fox O’Louglin as “illegal, shocking, and utterly devastating for writers.” O’Louglin added that “a book can take a year or longer to write. Meta has stolen books so that their AI can reproduce creative content, potentially putting these same authors out of business.”

Three of my novels pirated for AI training

.

Reflecting many authors’ outrage throughout the world, Novelist AJ West remarked, “To have my beautiful books ripped off like this without my permission and without a penny of compensation then fed to the AI monster feels like I’ve been mugged.” Australian Author Sophie Cunningham said, “The average writer earns about $18,000 a year on their writing. It’s one thing to be underpaid. It’s another thing to find that [their] work is being used by a company that you don’t trust.” Bestselling author Hannah Kent said, “If feels a little like my body of work has been plundered.” She adds that this, “opens the door to others also feeling like this is an acceptable way to treat intellectual copyright and creatives who already…are expected to [contribute] so much for free or without due recompense.” Both Kent and Cunningham exhort governments to weigh in with more powerful regulation. And this is precisely what may occur. Nicola Heath of ABC.net.au writes, “the outcomes of the various AI copyright infringement cases currently underway in the US will shape how AI is trained in the future.”

According to The March 20, 2025 Authors Guild article “Meta’s Massive AI Training Book Heist: What Authors Need to Know,” legal action is underway against Meta, OpenAI, Microsoft, Anthopic, and other AI companies for using pirated books. The Authors Guild is a plaintiff in the class action lawsuit against OpenAI, along with John Grisham, Jodi Picoult, David Baldacci, George R.R. Martin, and 13 other authors, but the claims are made on behalf of all US authors whose works have been ingested into GPT. 

The Authors Guild suggests five things authors can do to defend their rights:

Send a formal notice: If your books are in the LibGen dataset, send a letter to Meta and other AI companies stating they do not have the right to use your books.Join the Authors Guild: You should join the Guild and support our joint advocacy to ensure that the writing profession remains alive and vibrant in the age of AI. We give authors a voice, and there is power in numbers. We can also help you ensure that your contracts protect you against unwanted AI use of your work. Protect your works: Add a “NO AI TRAINING” notice on the copyright page of your works. For online work, you can update your website’s robots.txt file to block AI bots.Get Human Authored certification: Distinguish your work in an increasingly AI-saturated market with the Authors Guild’s certification program. This visible mark verifies your book was created by a human, not generated by AI.Stay informed. The Authors Guild suggest signing up for the free Guild biweekly newsletter to keep updated on lawsuits and legislation that could impact you and your rights. The legal landscape is changing rapidly, and they are keeping close watch.

How do I feel about all this? As a female Canadian author of climate fiction? As a thinking, feeling human being living in The Age of Water? Well, to tell the truth, it kinda makes me want a donut*…

Below are the top ten candidates selected from over 2 thousand nominations:

I decided to nominate the bdelloid rotifer and found my candidate in the top ten! 

The rotifer didn't win the top designation of Invertebrate of the Year; that went to the charismatic tardigrade. That's ok; the tiny rotifer got its brief recognition. Hail the resilient rotiter!

Writing in the Age of Artificial Intelligence: AI and Post-Plagiarism

I teach academic writing to students at the University of Toronto Writing Centre. It’s wonderful and fulfilling work and I enjoy helping students in several disciplines (engineering, health sciences, social sciences) learn to write better. As with the rest of the academic world of writing, we are all making sense of the use of AI-generated tools by students, instructors and researchers: large language models (LLMs) such as ChatGPT, Claude, Copilot, and even Grammarly. Students have told me that they found AI helpful in brainstorming and outlining as well as organizing literature reviews and editing for grammar and such. A recent survey of universities and corporations around the world by the Digital Education Council revealed that a majority of students used AI tools. Of those surveyed, close to two thirds used AI as a search engine; a third used it to summarize documents; and a fifth used it to create first drafts. 

In her 2024 article “The Future Is Hybrid”, Beth McMurtrie suggested that genAI “may eventually take its place in the pantheon of game-changing technologies used every day in education—alongside calculators, search engines, and Excel.”

In my other pursuit as a professional fiction author, I see the artistic and communication industries embracing AI, particularly in the visual arts. I’m now told that several publishing houses and magazines have dedicated efforts to publish AI-generated work. Some magazines are entirely AI generated, Copy Magazine, for instance. Author futurist Bernard Marr writes that “Generative AI is already being adopted in journalism to automate the creation of content, brainstorm ideas for features, create personalized news stories, and produce accompanying video content.” Marr then goes on to provide 13 ways that all writers should embrace Generative AI that includes anything from drafting plot lines to world building. Sports Illustrated was recently found to publish AI generated stories. Even newspapers, such as the LA Times, the Miami Herald, and Us Weekly acknowledge AI-written content. And I recently learned that one of the top five online science fiction magazines, Metastellar, accepts AI-assisted stories with the proviso that “they better be good.” And Metastellar provides some convincing reasons. This has become a hot topic among my fellow professional writers at SF Canada.  One colleague informed me that a “new publisher Spines plans to disrupt industry by publishing 8000 AI books in 2025 alone.” On checking the news release, I discovered that Spines is, in fact, a tech firm trying to make its mark on publishing, primarily through the use of AI. The company offers the use of AI to proofread, produce, publish, and distribute books. They are, in fact, a vanity publishing platform (essentially a service for self-publishing), charging up to $5000 a book and often taking just three weeks to go from manuscript to a published title.

The emerging field of AI-assisted writing and communicating is a burgeoning field that promises to touch every person in some way—writers and readers alike. Tech companies are scrambling to use it to save time and effort. Others are involved in improving current and developing new models. Many are training LLMs for improved use. Even I was headhunted as a creative writer by one tech firm to help create more safe, accurate and reliable LLMs.

Universities and Other Educational Institutions Use of AI

How universities and other educational institutions are dealing with the challenge and promise of these emerging tools in communication varies from out right forbidding AI use in the classroom to full on acceptance and obligatory use in some classroom projects. McMurtrie described how two instructors at Rollins College, Dan Myers and Anne Murdaugh, had students collaborating with AI on semester-long research projects. They were instructed to use Claude and Copilot to brainstorm paper topics, conduct literature reviews, develop a thesis, and outline, draft, and revise their papers. Myers and Murdaugh asserted that “the skills that students use to engage thoughtfully with AI are the same ones that colleges are good at teaching. Namely: knowing how to obtain and use information, thinking critically and analytically, and understanding what and how you’re trying to communicate.”

In fall of 2024, Stephanie Wheeler and others at the department of writing and rhetoric in the University of Central Florida, along with their philosophy department, set up an interdisciplinary certificate in AI. Their purpose was to develop conceptual knowledge about AI. Wheeler asserted that writing and rhetoric have long been concerned with how technology shapes these disciplines. Sharon L.R. Kardia, senior associate dean of education at the University of Michigan argued that AI could greatly benefit public health in its ability to aid in data analysis, research review, and the development of public-health campaigns. However, she cautioned that LLMs also absorb and reflect the social biases that lead to public-health inequities.

One of my Writing Centre colleagues at UofT recently shared some thoughts about a conference session he’d participated in, in which a student panel listed tasks that they thought genAI cannot do (yet). These included: generate music, offer interpersonal advice, and verify facts; I think AI can already help with two of these. Chad Hershock, executive director of the Eberly Centre for Teaching Excellence and Educational Innovation at Carnegie Mellon University shared that they are researching key questions about whether AI enables or impedes: does using AI while brainstorming generate more or fewer ideas? Can generative AI give less-experienced students a better chance to be successful in technical courses? To what extent does using AI help or hinder writing skills? Does having generative AI as a thought partner enhance students’ ability to make a claim and support it with evidence?

My own experience with a less-experienced student’s use of genAI was often abysmal. The student had used the tool as a crutch and had failed to learn from their use of the tool. This suggests that the most important limitations of the tool lie with the user’s own limitations and it points to the need for guidance by educators.

In her 2024 Axios article “Why AI is not substitute for human teachers” Megan Morrone described findings of the Wharton School on access to genAI: while genAI tutors improved student performance on practice math problems, students who used these tools performed significantly worse on exams (where they couldn’t use AI). The school concluded that the students used genAI to copy and paste answers, which led them to engage less with the material. Wharton School associate professor Hamsa Bastani argued that, “if you just give unrestricted access to generative AI, students end up using it as a crutch…[and] end up performing a lot worse.” This is partly because students—often stressed-out by heavy work loads—find that LLMs save time and can produce content close to what the user might produce themselves. Researchers have even come up with a term for this: Cognitive Miserliness of the User, which, according to writer Stephen Marche, “basically refers to people who just don’t want to take the time to think.”

Melanie M. Cooper, chemistry professor at Michigan State University cautioned that while “there’s a lot of ebullience in the AI field, it’s important to be wary.” She argued that it is easy  to misuse AI and override the system to get a quick answer or use it as a crutch.  McMurtrie shares that, while “AI evangelists promise that these tools will make learning easier, faster and more fun,” academics are quick to reject that rhetoric. McMurtrie ends her article with a cautionary statement by Jennifer Frederick of Yale: “Universities really need to be a counterpoint to the big tech companies and their development of AI. We need to be the ones who slow down and really think through all the implications for society and humanity and ethics.”

Considering the impact of artificial intelligence on writing, Dr. Sarah Elaine Eaton, professor at the University of Calgary, introduced the idea of life in a postplagiarism world. She expanded on her ideas to come up with six tenets that characterize the post-plagiarism age. These include:

Hybrid human-AI writing will become normalHuman creativity is enhancedLanguage Barriers disappearHumans can relinquish control, but not responsibilityAttribution remains importantHistorical definitions of plagiarism no longer apply 6 tenets of Postplagiarism (image from Sarah Elaine Eaton)

Eaton’s fifth point (attribution remains important), I think becomes all that more important in the presence of AI use. Transparency in presentation, particularly in an academic setting, takes on a new level of importance when communicating with tools such as generative AI. Where things come from, which tool was used and how it was used are key to understanding and interpreting the nature of the writing itself. The path taken to the destination becomes all important when interpretation and comprehension (and replication) is required. To fully understand “where you are”; we need to know “how you got there.” It’s like solving math problem; if you don’t show your work and just provide the answer, I have no way of knowing that you actually understood the problem and really solved it.

I am certain that generative AI will continue to take on various forms that will continue to astonish. Its proper use and development will serve humanity and the planet well; but there will always be abusers and misusers and those who simply don’t care. We must be mindful of them all. We must remain vigilant and responsible. Because, just as with freedom, if we grow lazy and careless, we run the risk of losing so much more.

Through the Portal Anthology Gets Stellar Review

The recently released Through the Portal ecofiction anthology that I co-edited with Lynn Hutchinson Lee and published by Exile Editions, received a wonderful in-depth review by author Lisa Timpf in The Seaboard Review. Here are some highlights of Timpf’s review of this anthology of hopeful dystopian short stories, flash fiction and poetry:  

 

"Mermaids, arborists, and pollinators are among the characters to be found in Through the Portal: Tales from a Hopeful Dystopia. Edited by Lynn Hutchinson Lee and Nina Munteanu, this eco-fiction collection gathers over thirty stories that fall under the general umbrella of hopeful dystopias…

 

Through the Portal offers intriguing and imaginative glimpses into the future. As [one of its short stories] “A Fence Made of Names” suggests, we often don’t appreciate what we have until we lose it. By showing us what we stand to lose, these stories offer a reason to increase our actions to preserve the planet…

While many of the tales hint at dark times ahead, it was refreshing to find so many that offered a ray of hope despite that. Whether it’s finding the will to live another day, returning to a better relationship with the land and the Earth, or taking steps to improve the world in even a small way, these stories affirm humanity’s potential for resilience in challenging times.

Will ingenuity, love, and respect for the earth help us work through whatever changes might lie ahead? Through the Portal offers hope that these qualities, if not enough in and of themselves, will help us find our way."

‘Through the Portal: Tales from a Hopeful Dystopia’ Anthology Releases December 31

 

Just before the Canada Postal strike halted mail dead in its tracks, I got a box full of books; pre-release copies of the anthology that Lynn Hutchinson Lee and I have been nurturing along from our idea three years ago when we pitched it to Exile Editions. 

 

I cracked open the box, like it was Christmas, and cuddled a book, so beautiful!

 

Ever since we had both had climate fiction stories appear in Exile Edition’s CLI-FI: Tales of Climate Change, Lynn and I had been discussing the possibility of collaborating on something. We liked the idea of something hopeful and Exile’s publisher agreed on the lure of something optimistic. We pitched the concept and Portal was born.

 

Writers, mostly Canadian, but also from the United States and around the world, submitted to us. We whittled down some 245 submissions to thirty-five stellar short stories and flash fiction that reflected the theme of the anthology: hope in the face of ecological adversity.

 

This was a labour of love, grounded in optimism and hope: to create a collection of optimistic dystopian short stories that celebrate the spirit of humanity in a changing world. As one reader said, “We definitely need more optimism and hope to offset the bombardment of negativity that is running rampant these days.”

 

Here’s how Exile represents the anthology on the back jacket:

 

Hopeful dystopias are so much more than an apparent oxymoron: they are in some fundamental way the spearhead of the future – and ironically often a celebration of human spirit by shining a light through the darkness of disaster. In Through the Portal: Tales from a Hopeful Dystopia, award-winning authors of speculative fiction Lynn Hutchinson Lee and Nina Munteanu present a collection that explores strange new terrains and startling social constructs, quiet morphing landscapes, dark and terrifying warnings, lush newly-told folk and fairy tales.

 

Exile further add about the contributors:

 

This is a fascinating collection of all-new, modern-day speculative storytelling, with insightful “Tales from a Hopeful Dystopia” featuring Agata Antonow, Sarah Christina Brown, Mary Burns, K.R. Byggdin, Petra Chambers, Katie Conrad, M.L.D. Curelas, Matthew Freeman, R. Haven, Liam Hogan, Cornelia Hoogland, Vanessa Hua, Jerri Jerreat, Zilla Jones, Katherine Koller, Erin MacNair, Melanie Marttila, Bruce Meyer, Isabella Mori, E. Martin Nolan, Avery Parkinson, Ursula Pflug, Marisca Pichette, Shana Ross, Lynne Sargent, Karen Schauber, Holly Schofield, Anneliese Schultz, Gin Sexsmith, Sara C. Walker, Jade Wallace, and Melissa Yuan-Innes. These authors show us that now, more than ever, our world urgently needs stories about hope.

Riding for the Tour de Cure BC

My son Kevin and his partner Lin cycled 260 km over two days for Tour de Cure BC this August Starting in Cloverdale and finishing in Hope, they helped raise over seven million dollars for cancer research and equipment. 

 

Saturday was their first day of the Tour de Cure. Kevin sent me a link to follow his ride in real time on Garmin. It was so cool to watch him move along the various roads to the finish line! On the first day, he and Lin went a hundred and sixty km (hundred miles) at an average of 20-22 kph for over 7 hours from Cloverdale to Chilliwack! 

 

They camped there overnight and started the following morning at 7:30, travelling 100 km toward the finish line in Hope. Good friend Anne and I drove to Hope to greet them at the finish line. It was so exciting and I confess I was very emotional. I was so proud of them both! 

 

After lots of hugging, we had some burgers for lunch then a beer at the beer garden and visited in Memorial Park (by the finish line). I noticed their mud-covered faces, particularly Lin’s—and how very clean Kevin’s jersey looked—and it was explained to me that cyclists, when riding together, take turns leading and drafting each other(riding directly behind) to get a break while the leader breaks the wind and sets the pace; hmmm… what was Kevin doing? 

 

Kevin and Lin got a ride back with their bikes and Anne and I made our way back to Ladner, where Anne lives and I was visiting from Ontario. We celebrated with an ice cream cone! 

 

You can still donate through Kevin's page here:

Thanks so much!

In gratitude,

Diatom Forest as Water Quality Indicator: H2O Publishes my Illustration

My original illustration for my article on Diatom Forests
 

This past spring, Dutch scientist Herman van Dam (Consultancy for Water and Nature) approached me for permission to use my illustration of the diatom forest in a paper he and co-authors were preparing for the Dutch journal H2O. He explained that they wanted to help familiarize water managers who read the journal with the underwater biodiversity for which my illustration would be helpful.

 

The Illustration

 

He’d seen my illustration in my article “A Diatom Spring” in The Meaning of Water. Below is a summary of my article about the diatom forest:

 

Attachment and colonization starts with a ‘clean’ unpopulated surface (usually scoured by turbulence in a storm or some other event or a new surface tumbled into the water). Several stages of succession take place, starting with early colonizers. The adnate Cocconeis placentula, whose frustules attach directly to the substrate, is an example of an early colonizer. When they attach to a substrate they form a biofilm (think moss in a terrestrial forest). Adnate species are eventually overgrown by taxa that produce a mucilaginous pad (e.g. Synedra) or stalk (e.g. Gomphonema). The understory layer is typically occupied by diatoms such as Fragilaria vaucheriae and Synedra radians that attach to the surface at one end (apical) of their rod-shaped frustules using a mucilaginous pad to form “rosettes” that resemble spiky understory shrubs. This allows them to protrude above the adnate taxa and take advantage of more light.

Fragilaria and Synedra forming "rosettes" on substrate

 

The diatoms Cymbella and Gomphonema produce long stalks that attach directly to the surface, allowing them to form a swaying canopy over the lower tier of cells of Fragilaria vaucheriae, Synedra radians and early colonizer Cocconeis placentula whose frustules attach directly to the substrate (think overstory and understory of a terrestrial forest or a marine kelp forest).

SEMs of colonizing stalked diatoms

 

The Diatom Forest Structure

 

Just like trees, the canopy-forming stalked diatoms effectively compete for available light and nutrients in the water with their vertical reach. They provide the ‘overstory’ of the diatom forest’s vertical stratification. These tree-like diatoms also provide an additional surface for other diatoms to colonize (e.g. tiny epiphytic Achnanthes settle on the long stalks of Cymbella, just as lichen does on a tree trunk).

 

The stalked diatom forest acts like a net, trapping drifting-in euplankton, such as Pediastrum sp. andFragilaria spp., which then decide to stay and settle in with the periphyton community. The mucilage captures and binds detrital particles in both lower and upper stories of the diatom forest; these, in turn, provide nutrients for the diatom forest and additional surfaces for colonization. In their work with periphyton communities, Roemer et al. (1984) found several diatoms (e.g. Diatoma vulgare, Fragilaria spp. Stephanodiscus minutula) entangled in the complex network of cells, stalks, and detritus of the diatom forest’s upper story. They also found rosettes of Synedra radians—like jungle orchids—attached to large clumps of sediment caught by the net of mucilage.

 

Eventually, ‘overgrowth’ occurs as the periphyton colony matures and grows ‘top-heavy’ with all this networking. The upper story of the community simply sloughs off—usually triggered by turbulence in a river from rains, storms, or dam release. This is similar to a forest fire in the Boreal forest, which creates space and light for new colonization and growth. The dislodged periphyton ride the turbulent flow, temporarily becoming plankton, and those that survive the crashing waters provide “seed” to colonize substrates downstream. Others may get damaged and form the ‘dish soap’ like suds or foam you often see in turbulent water. The proteins, lignins and lipids of the diatoms (and other associated algae) act as surfactants or foaming agents that trap air and form bubbles that stick to each other through surface tension.

The Paper

 

The paper was published June 13, 2024, in H2O, written by Jako van der Wal, Joep de Koning and Herman van Dam, and entitled “Snel inzicht in de ecologische waterkwaliteit met diatomeeën”(Quick insight into ecological water quality with diatoms).This paper was right up my alley! As a diatom specialist and limnologist who studied them in relation to environmental conditions and perturbations, I was intrigued by the paper and gained some additional insight on diatom ecology. 

 

Van der Wal et al. cited recent advances in DNA-based identification methods that provide fast and cheap diatom identification over the traditional method of using an optical compound microscope to observe morphological characteristics such as size, shape and ornamentations of the silicified cell wall. I can attest that this is a labour-intensive process in which I spent many hours and days hunched over a microscope during my masters research at Concordia University. This efficient DNA-identification has seen a resurgence of using diatoms as a valuable tool for water quality managers, with applications providing insight into both current and historical water conditions. The authors argue that benthic diatoms or periphyton(living on substrates such as plants, rock, sand and artificial surfaces) have been since the 1980s used as indicators of saproby, trophy, acid and salt character in, among other things, ditches and canals. For every type of water and water quality, there are diatoms that have their habitat there, write the authors. They argue that, unlike phytoplankton, fish and macrofauna, periphyton attach to a surface and hardly move; this means that effects of water quality can be demonstrated locally. Because many diatom species tolerances and intolerances are known and they reproduce quickly (over days), diatoms respond quickly to changes in the environment—much faster (often within weeks) than other ecological indicators. 

 

Scientists and water technicians can use diatom species composition to measure perturbations by organic material, low oxygen content, eutrophication, and toxicity. Given that diatoms colonize and develop quickly, this includes unstable and damaged habitats where other indicators cannot develop, such as shipping traffic, waves or where cleaning or dredging is carried out regularly. Historical insight can be provided by diatoms, given that their silica frustules are naturally preserved in sediment.

My Own Work with Turbulence

 

During my masters research in several streams in the Eastern Townships, I examined how diatoms colonized artificial substrates; how they formed productive biofilms that sustained an entire periphyton community of attached aquatic life and discovered that their pattern of colonization related to current speed and direction. I submerged glass slides (the kind people use to look at critters under the microscope) in a device in the stream and oriented them parallel or perpendicular to the current.

There are two ways an algal community grows in a new area: (1) by initial colonization and settling; and (2) by reproduction and growth. I studied both by collecting slides exposed for differing lengths of time (collecting young and mature communities) in different seasons.

Nonrandom diatom colonization across a microscope slide

I discovered that the diatoms colonized these surfaces in weird ways based on micro-turbulence. Early colonizers, like Achnanthes and adnate Cocconeis preferred to settle on the edges of the slides, where the chaos of turbulence ruled over the sheer of laminar flow. They colonized by directly appressing to the substrate, making them the first photosynthetic taxa to establish a biofilm on a clean substrate. Vadeboncoeur and Katona (2022) write that “in waved-washed surfaces, these taxa may be the only algae that persist.” I postulated that the drift velocity was reduced on the slide’s edge, where turbulence was greatest, giving drifting algae a greater chance to collide and settle on the slide over the more shear laminar flow along the slide’s central face.

 

Once settled, the community was more likely to grow with turbulence. Greater turbulence decreases the diffusion gradient of materials around algal cells, with a higher rate of nutrient uptake and respiration. Turbulence provides greater opportunity to an existing colony by increasing “chaotic” flow, potential collision and exchange. Turbulence is a kind of “stable chaos” that enhances vigor, robustness and communication.

Using Diatoms in Water Quality Assessments

 

Van der Wal et al. argued that in environmental assessment the DNA-identification is just one step in a process that looks a population structure and health. Diatoms are already used in 21 of the 27 EU countries as part of a Water Framework Directive (WFD) quality index for flowing waters and in nine EU countries for standing water. Example conditions and associated perturbations where diatoms are a particularly useful indicator include: salinity, acidity, oxygen saturation, organic load (saproby), nutrient richness (trophy), temperature, and toxicity.

 

Diatom Growth Forms & Deformities

 

Van der Wal et al. argue that in addition to the different species compositions and the related ecological indices, growth forms and deformations of diatoms are useful indicators of water quality, particularly in relation to specific toxins.

 

Growth forms of diatoms can be described as attached, short-stalked, long-stalked, mobile and living in mucous tubes (Figure 3, van der Wal et al., 2024). Each growth form has advantages and disadvantages. For example, short-stalked diatoms are more difficult to graze and long-stalked diatoms come into contact with more water, from which they can then absorb substances. Long-stalked diatoms can also absorb more light if there is a lot of competition. Mobile diatoms can adapt to changing conditions by, for example, migrating from surface to subsurface and vice versa. Diatoms in slime tubes are more difficult to prey on and respond more slowly to environmental changes.

 

Van der Wal et al. cited work by Rimet & Bouchezwho found that long-stalked diatoms decline in waterbodies subjected to various pesticides. Falasco et al. also observed diatom deformities when exposed to various toxic substances. Heavy metals were observed to cause deformities in Navicula and nitrogen toxicity was also implicated in diatom deformities.
