When Water Speaks: quotes from A Diary in the Age of Water

“Water wants to flow. It doesn’t like to be restricted. If confined in a ravine, it speeds up and cuts a channel along the thalweg, eroding the hardest material and polishing a path that uniquely suits it. Water is selfish. It is always moving, even when it isn’t.”

Lynna Dresden

A Diary in the Age of Water is “An exceptional and thought-provoking dystopian fiction.”

When Water Speaks: quotes from A Diary in the Age of Water

“Mankind will continue to flounder when he underestimates Nature and sees himself separate from Her. Man is having his way with Her now. But eventually She will have her way with him. When they try to hang onto water, it will slip through their fingers. That’s what water does.”

Una Dresden

“In poetic prose with sober factual basis, Munteanu transmutes a harrowing dystopia into a transcendentalist origin myth. An original cautionary tale that combines a family drama with an environmental treatise.”

When Water Speaks: quotes from A Diary in the Age of Water

“Don’t make the mistake of thinking the bully is your friend…You can play with the bully. But don’t make him your friend. Demand his respect. Or you will become the bully.”

Una Dresden

“Lyrical and dystopian, ‘A Diary in the Age of Water’ is as much an ode to water as it is a cautionary tale about the dire implications of climate change.”

Apex Magazine Interviews Nina Munteanu About Story, Ecology, and the Future—Part 2

Issue  #128 of Apex Magazine featured an interview that Rebecca E. Treasure did with me, posted on December 10, 2021. We discussed the power of story, the use of dystopian narrative, and the blur between fiction and non-fiction to create meaningful eco-fiction. Here’s part two of the interview. For the complete interview go here:

INTERVIEW

Nina Munteanu, author of “Robin’s Last Song,” is a prolific creator with multiple books, podcasts, short stories, and nonfiction essays in publication. Her work spans genre, from eco-fiction to historical fantasy to thrillers, and of course, science fiction. Her work as an ecologist informs all of her writing, which circles around an essential exploration; the relationship between humanity and our environment.

 At the top of Nina Munteanu’s website, there is a quote: “I live to write, I write to live.” This sentiment is reflected in her fiction, which is not just about characters in compelling situations solving their problems with compassion, but is about all of us, our planet, our environment, and our future.

Nina Munteanu sat down with Apex for a conversation about story, ecology, and the future.

APEX MAGAZINE: Your novels and short stories examine the role and evolution of humanity in the context of nature and technology. As an ecologist, what do you believe needs to happen—internationally, nationally, locally, and personally—to restore our planet and move forward in a sustainable way?

NINA MUNTEANU: All things animate and inanimate naturally oscillate toward equilibrium or balance in a kind of stable chaos of polarities. Goethe and Hegel told us this long ago. Our actions have exacerbated this oscillation through massive extraction, habitat destruction, and pollution with associated conflicts, take-over and subjugation. Everything is connected and all have contributed to climate change and habitat change. Our mission—given that we’re responsible for much of that imbalance—is to help the planet return itself to balance. That means ensuring that Nature’s natural checks can do their job to ensure functional forests and phytoplankton, a healthy ocean, a resilient biodiversity—all systems that we rely on for our own healthy existence. Restoring our denuded global forests, and the oceans will need the concerted and united efforts of all nations and individuals. We have the knowledge, the science, and technology; all that is needed is the will. And that can only change as our own narrative changes. That’s where storytelling plays a key part. Surveys have proven that fiction can be deeply persuasive through character journey that convinces at a deeper more emotional level (as opposed to a litany of facts that appeals only at an intellectual level).

AM: Do you believe industry and sustainability are compatible? What about colonialism and sustainability? Capitalism? In other words, is sustainability something we can achieve with our current systems, or is global systemic change required?

NM: Some people—mostly economists—would say definitely yes to the first question; we just need to be conservationist in our approach to doing business. But the very basis of capitalism is exploitation, not conservation. The driving force behind capitalism is fear and uncertainty and its main process is exploitation. From an ecologist’s perspective, this makes sense for a community during its early succession and growth stage …  when it first colonizes a new area. Ecologists call this approach r-selected (for rate), based on the need to be profligate and fast-growing to successfully establish. But as we reach a climax community and our carrying capacity—where we are now—this r-selected approach no longer works. We need an economic model that better matches this new paradigm. NOT based on continued growth! A climax global economy, one based on cooperation not competition. Elisabet Sahtouris calls this ecological economy “ecosophy.” In his book Designing Regenerative Cultures, Daniel Christian Wahl talks about changing our evolutionary narrative from one based on fear defined by a perception of scarcity, competition, and separation to one based on love defined by a perception of abundance, a sense of belonging, collaboration, and inclusion. He promotes a regenerative economy based on true reciprocation.

And moving forward we can take a lesson from Robin Wall Kimmerer who promotes a gift economy—an economy of abundance—whose basis lies in recognizing the value of kindness, sharing, and gratitude in an impermanent world. This is what she says: “Climate change is a product of [our] extractive economy and is forcing us to confront the inevitable outcome of our consumptive lifestyle, genuine scarcity for which the market has no remedy. Indigenous story traditions are full of these cautionary teachings. When the gift is dishonored, the outcome is always material as well as spiritual. Disrespect the water and the springs dry up. Waste the corn and the garden grows barren. Regenerative economies which cherish and reciprocate the gift are the only path forward. To replenish the possibility of mutual flourishing, for birds and berries and people, we need an economy that shares the gifts of the Earth, following the lead of our oldest teachers, the plants.”

AM: The language in your stories is richly thematic, using strong description to weave the subtext into the piece. For example, “killing two squirrels with one stone.” Is that something that comes about organically as you compose a piece, or a more intentional part of editing?

NM: I use both processes to achieve a final narrative that is multi-layered with metaphor, symbols, and deep meaning. The first process is through intuition derived through intimacy; the second process is more deliberate and generated through objectivity. Insights from intimacy come about organically, during moments of true inspiration, when my muse connects me to the deeper truth of a character’s voice and actions. Given that the inner story runs many layers (some of which I, as writer, may not even be overtly aware) and links in a fractal relationship with the outer story, those moments of inner inspiration happen as if of their own accord. That’s what writers mean when they admit that their characters “talk” to them and instruct them on what to write. When a writer achieves that level of intimacy and understanding, they can let the muse guide them.

Much of the description that is woven into story is generated through the editing process when I read the manuscript as a reader. The process involves letting the story sit for a while so when I return to it, I am reading more objectively. During this process, I apply my knowledge in storytelling craft to showcase combustible moments in plot, and work in foreshadowing, subtext, and compelling metaphor. A writer can’t add metaphor without context related to story theme (otherwise this may result in what the industry calls “purple prose”). Metaphor—given its roots in the deeper psyche of a culture—must arise organically from a deep, sometimes intuitive, understanding—where the personal meets the universal.   

AM: Your work takes complex topics that are nonetheless critical to humanity’s future and pulls stories with compelling characters out of them, making the science accessible, the warnings personal to the reader. This has always been one of the callings of science fiction. What is the role of stories in the climate action movement?

NM: Our capacity and need to tell stories is as old as our ancient beginnings. From the Paleolithic cave paintings of Lascaux to our blogs on the internet, humanity has always shared story. Story is powerful in how it helps us define who we are, what’s important to us, and where we are going. Stories compel with intrigue, stir our emotions, connect with our souls through symbols, archetypes and metaphor. Stories inspire action. We live by the stories we tell.

For too long, our stories have promoted a dominant worldview of exploitation and capitalism. We’ve been telling the patriarchal story of “othering” for too long; we need a new voice and a new worldview to replace our old stories of conquering and taming a “savage land” and “savage people.” When Copernicus proclaimed in 1543 that the sun did not revolve around the Earth, it took a long time for the world to accept and let go of its Ptolemaic Earth-centered view. But the world did come around eventually to the point now that this is common knowledge and lies embedded in our daily lives and language.

Storytelling about how the Earth takes care of us and how we can take care of Earth is urgently needed. This means shifting our stories from an exploitive capitalist narrative of separation toward an inclusive partnership narrative. This means embracing a more eco-centric worldview; a worldview in which humanity is not central, but lies embedded within greater planetary forces and phenomena. A worldview that sees humanity only as part of a greater entity, as participant in a greater existential celebration of life and the elements. A humanity that must learn to play along, not bully and take over. A humanity that must embrace compassion, respect and kindness; a humanity directed by humility—not hubris. It is my firm belief that until our worldview embraces humility in partnership with the natural world—until we cast off our self-serving, neo-liberal, capitalist ideologies—we will remain hampered in our journey forward. When we change our stories, we change our lives and we change the world along with it.

This is already happening with the emergence of a strong eco-voice by writers through the feminine voice, the gylanic voice, the voice of the marginalized, of ecology and the environment itself. Authors such as Barbara Kingsolver, Annie Proulx, Margaret Atwood, Richard Powers, Emmi Itäranta Cherie Demaline, Grace Dillon, and Cormac McCarthy give Nature a face and voice to care about. And caring is the first step.

AM: Your stories also bridge fiction with nonfiction, using speculative fiction as a lens to bring your subject into focus for the reader. How does that work? Why do you approach story in this way?

NM: Marcie McCauley with Temz Review observed that, “[Munteanu] does not appear to view fiction and non-fiction as separate territories; or, if she does, then this book [A Diary in the Age of Water] is a bridge between them.” In Herizons, Ursula Pflug called the book “a bit of a hybrid, and Munteanu a risk-taker.” Buried in Print wrote of the same book, “ultimately it exists in an in-between place, some mystical elements of the generational tale possibly alienating the dedicated science-y readers and the instructional elements possibly alienating fiction devotees. And, yet, I read on: strangely compelling.”

I find that I enjoy this in-between place that blurs fiction with nonfiction. It’s more edgy, gripping, and believable, albeit fantastical, even playfully challenging at times. For instance, I may subvert facts, creating semi-facts to tease the discerning reader (e.g. when the diarist in “A Diary in the Age of Water” observed that President Trump had gone blind from staring at the sun during an eclipse; while Trump did stare directly at the sun without eye protection during an eclipse in 2017, he did not go blind—yet). Readers have told me that the story was more impactful; they honestly didn’t know what was taken from fact and what was fictionalized. Such narrative reads like a true story and there is little more tantalizing than eavesdropping on another’s real experience and intrigue. The risk—that the blur will either confuse the reader or invalidate its truths and message—is hopefully addressed through compelling narrative that engages the reader. But this is also why I tend to include an extensive bibliography at the end of a novel or short story.

Readers have told me that my fiction/nonfiction storytelling trope, like “mundane science fiction,” grips my stories with a more keen sense of relevance. Given that I am writing mostly climate fiction and eco-fiction these days, that sense of relevance is exactly what I wish to achieve. 

AM: A last question. Both “The Way of Water” and “Robin’s Last Song” showcase the relationships women have with each other, the importance of human connection, the damage that disconnecting from each other can do and, inversely, the power of connection. In your view, what is the role of individuals and local communities in the climate crisis?

NM: There are many things we can do as individuals and as part of a community. I was recently asked this question by the Toronto Star and I responded with three things:

●      First, plant a tree; make an actual difference through action. By doing that, we get out from hiding under the bed and face the monster of climate change and show that we care and that we are not alone.

●      Second, vote for green politicians. Politicians need to hear directly from their communities. They need you to push them to act on climate change.

●      Third, find your tribe and create a movement. Everyone says that people have the power, but that power comes best through numbers and solidarity. Find your tribe and you’ll find yourself more motivated. So, start with you and your home: plant trees; put in a rain garden; put in permeable driveways and solar panels; lower meat intake, especially beef; don’t buy bottled water. Then connect with your physical community and social media community. Let them know what you’re doing and why. Work with your community. All members of a community can help change how your street looks and behaves by communicating with your local government, attending meetings, and having a voice. Initiate a tree-planting program in your parks and street greens. Do stream or lake cleanups. Let the leaders of your community know you care and are willing to do something about it. The wave of change starts local and ripples out into a global phenomenon. Change comes from the heart and heart is where the home is.

Nina Munteanu On The Age of Water: Interview on “Mysterious Goings On Podcast”

Alex Greenwood, host of The Mysterious Goings On Podcast recently interviewed me about my latest novel and work of climate fiction, the dystopia “A Diary in the Age of Water.”

Alex and I discussed water scarcity and climate change as a water phenomenon. I also shared my thoughts on water as a character in the novel, water’s many anomalous properties–all of which promote life and wellness, and why writing a dystopian cautionary tale is an act of optimism.

Nina Munteanu Reads on “Sample Chapter Podcast”

I recently appeared on Episode #142 of award-winning “Sample Chapter Podcast” where I had a wonderful interview with Jason Meuschke and read a sample chapter from my recent eco-novel “A Diary in the Age of Water.” 

Jason and I talked about the writing process; what makes good and compelling fiction; creating realistic and interesting characters with flaws–like my flawed detective Rhea Hawke in The Splintered Universe Trilogy‘ writing eco-fiction in which environment can be a character; the “what ifs” in historical fiction and where we get our ideas (The Last Summoner came to me in a dream and later through a single image).

This is what Jason said about Episode 142 of The Sample Chapter Podcast with Nina Munteanu:

Episode 142 is here with a truly delightful author from Canada, Nina Munteanu. In the episode, Nina and Jason discuss character flaws, having the environment be a character in our prose, the “what ifs” in historical fiction, the writer’s “wavelengths”, and much more all before enjoying a magical chapter reading. Enjoy!

“A Diary in the Age of Water” Reviewed by Kirkus Reviews, The Winnipeg Free Press and The Miramichi Reader

Nina Munteanu’s cli-fi eco-novel “A Diary in the Age of Water” just released in summer of 2020 received several favourable reviews from Kirkus ReviewsThe Winnipeg Free Press, and The Miramichi Reader. The speculative novel about four generations of woman and their unique relationship with water was recently awarded the Literary Titan Award for a book that “expertly delivers complex characters, intricate worlds, and thought provoking themes. The ease with which the story is told is a reflection of the author’s talent in exercising fluent, powerful, and appropriate language.”

“While bringing attention to the current politicization of climate change, the story maintains important underlying themes like family, love, forgiveness, and the complexity of the human soul. The author has gone to great lengths to show that there are different layers to each character, none fully evil nor fully good. A Diary in the Age of Water is an exceptional and thought-provoking dystopian fiction.”
—LITERARY TITAN (4-star)

“In Canadian ecologist Munteanu’s novel, a child in a world of climate disaster discovers hidden truths about the past in a mysterious journal. In a story set centuries in the future, a young girl with four arms named Kyo lives on the last vestige of a planet damaged by climate crisis, water scarcity, and a cataclysm brought on by semi-divine figures called the Water Twins. Kyo comes across the 21st-century journal of a limnologist named Lynna; over two decades, the journal’s author details Earth’s fate with scientific observations on the harm wrought by corporate greed, as well as her own personal struggles raising a child in a world of catastrophe and authoritarianism. She’s a deeply relatable and tragically flawed character who’s wracked by doubt, fear, and cynicism—a stark contrast to her fierce environmentalist mother, Una, and her spiritual, idealistic daughter, Hildegard. What unites them all is the study of water: its intrinsic properties, its mysteries, and ultimately its necessity to the planet. In poetic prose (“We’re going down in a kind of slow violence”) with sober factual basis, Munteanu transmutes a harrowing dystopia into a transcendentalist origin myth…the author asks uncomfortable questions and explores the effects of one generation’s actions upon the next as they ripple outward like a stone dropped in a pond. A sobering and original cautionary tale that combines a family drama with an environmental treatise.”
—KIRKUS REVIEWS

Futuristic novel awash with water warnings

“An engaging epistolary novel. An ecologist and environmental activist herself, Munteanu has no difficulty voicing a fully formed literary character who is both scientifically literate enough to understand how quickly human society is entering its final ebb, and humane enough to mourn the fullness of this tragedy.

The prose here is beautiful and purposeful in the tradition of environmentally and socially minded novelists such as Ursula K. Le Guin and Margaret Atwood… It comes down to water: ice sheets, rain and drought, the loss of water tables and the collapse of marine ecologies in an acidifying ocean. The pulse and rhythm of life on this planet is water. Its death throes, too, can be read in the flow of water.

Munteanu has produced something which joins George Orwell and Aldous Huxley, Le Guin and Atwood, a warning of the direction we are heading that will be valuable even if we manage to avert disaster.”
—Joel Boyce, WINNIPEG FREE PRESS

“A Diary in the Age of Water commands reader interest on a number of levels…a chilling but believable portrayal of what might happen as fresh water becomes scarcer… Munteanu’s novel provides a cautionary note for what might happen if we fail to pay attention to this precious resource.”
—Lisa Timpf, MIRAMICHI READER

Short Synopsis

A Diary in the Age of Water follows the climate-induced journey of the Earth and humanity through four generations of women, each with a unique relationship to her world and to water. Water plays both metaphoric and literal roles in this allegorical tale of humanity’s final journey from home—where male sterility, heat-shock proteins, horizontal gene transfer, and virgin-births rule a changing world of water securitization through ambitious environmental manipulation (e.g., resurrecting the US Army Corps of Engineers 1960s NAWAPA/CeNAWP plan to create the 800 km long Rocky Mountain Trench reservoir and divert most of northern Canada’s water to the USA—drowning a fifth of BC). 

Told in far-future and near-future frames, the central part of the story is a diary by a limnologist, whose personal account creates a terrifying realism to the geo-political tension of water securitization, plague containment, and police oppression—the diary spans from 2045 to 2064 (when the diarist disappears herself). 

The cli-fi novel begins centuries from now in the dying northern boreal forest with young KYO, a blue water nymph with multiple arms who dreams of the past and of being a normal human. She is on her way to the library to memorize a textbook on the Age of Water and there discovers a piece of her past from that age when The Water Twins destroyed the world. Kyo discovers a diary by a limnologist (who happens to be the mother of one of the Twins). Intrigued, Kyo drops the textbook and reads the diary. The diary, by cynical limnologist LYNNA, describes a near-future Toronto in the grips of severe water scarcity. The gritty memoir describes Toronto in a time when China owns the USA and the USA owns Canada, and aggressively mines its water. While lamenting the greed and destructive nature of her race, Lynna self-servingly helps murder three people; she also gives birth to rebel daughter HILDA (one of the Water Twins) who destroys her world through water and gives virgin-birth to the next stage in human evolution: a mutant who becomes one of the Disappeared who returns centuries later in a dying world as the water keeper Kyo. 

“A Diary in the Age of Water” explores identity and our concept of what is “normal”—as a nation and an individual—in a world that is rapidly and incomprehensibly changing.

How the Bdelloid Rotifer Lived for Millennia — Without Sex

As a child, I always wanted a microscope.

I would have collected slimy waters from the scum ponds and murky puddles near my house. I would have brought them home and exposed them to the light of my microscope. I would then have peered deep into a secret world, where shady characters and alien forms lurked and traded.

It would be many years, when I was in college, before I finally witnessed this world—so alien, it might have inspired the science fiction books I wrote later as an adult. As it turned out, I was led to pursue a Masters of Science degree, studying periphyton (microscopic aquatic communities attached and associated with surfaces like rocks and plants) in local streams in the Eastern Townships of Quebec.

While my work focused on how diatoms (glass-walled algae) colonized surfaces, micro-invertebrates kept vying for my attention. Water fleas (cladocerans), copepods, rotifers, seed shrimps (ostracods) and water bears sang across my field of vision. They flitted, lumbered, wheeled and meandered their way like tourists lost in Paris. But this wasn’t Paris; I’d taken the blue pill and entered the rabbit hole into another world…

Sketch of common zooplankton and phytoplankton (illustration by Nina Munteanu)

The Secret—and Dangerous—World of Micro-Organisms

Small Freshwater habitats are home to a highly productive and diverse collection of micro-invertebrates—multicellular animals that can barely be seen with the naked eye. Many average from 0.5 to 1 mm in size and resemble little white blobs; however, a scholar can distinguish each invertebrate by its unique movement. For instance, when presented with a jar of pond water, I can usually distinguish among the wheel-like wandering of a gastrotrich, dirigible-like gliding of an ostracod (seed shrimp), the vertical goldfinch-style “hopping” of the cladoceran (water flea) as it beats its antennae, or the halting-jerking movements of copepods (oar-feet) as their antennae drive them along like a dingy propelled by an amateur oarsman.

Alas, puddles, ephemeral ponds and vernal pools pose sketchy habitats, given their tendency to appear and disappear in a wink. And like the thief in the night, they pose a harsh and uncertain home to many small organisms. These environments are ever-changing, unstable, chaotic and unpredictable. Yet, anyone who has studied these variable ecosystems understands that they team with life. 

When a puddle or ephemeral pond dries up then reappears with rain, how can these communities thrive? Or do they all die off and then somehow recruit when the pond reappears? Many of these invertebrates have evolved creative ways to survive in very unstable environments. Some form a resting stage—a spore, resting egg or ‘tun’—that goes dormant and rides out the bad weather.

Philodina, a bdelloid rotifer (microscope photo by Bob Blaylock)

Animalcules & the Bdelloid Rotifer

In 1701, Antonie van Leeuwenhoek observed that “animalcules” (likely the bdelloid rotifer Philodina roseaola) survived desiccation and were “resurrected” when water was added to them. He’d discovered a highly resistant dormant state of an aquatic invertebrate to desiccation.

Dormancy is a common strategy of organisms that live in harsh and unstable environments and has been documented in crustaceans, rotifers, tardigrades, phytoplankton and ciliates. “Dormant forms of some planktonic invertebrates are among the most highly resistant … stages in the whole animal kingdom,” writes Jacek Radzikowski in a 2013 review in the Journal of Plankton Research. Radzikowski describes two states of dormancy: diapause and quiescence. (on right: sketch of bdelloid rotifer by Nina Munteanu

Bdelloid rotifers can go into quiescent dormancy at practically any stage in their life cycle in response to unfavorable conditions. Early research noted that dormant animals could withstand freezing and thawing from −40°C to 100°C and storage under vacuum. They also tolerated high doses of UV and X radiation. Later work reported that some rotifers could survive extreme abiotic conditions, such as exposure to liquid nitrogen (−196°C) for several weeks or liquid helium (−269°C) for several hours. Desiccated adult bdelloid rotifers apparently survived minus 80°C conditions for more than 6 years. The dormant eggs of cladocerans and ostracods also survived below freezing temperatures for years.

Rotifers are cosmopolitan detrivores (they eat detritus) and contribute to the decomposition of organic matter. Rotifers create a vortex with ciliated tufts on their heads that resemble spinning wheels, sweeping food into their mouths. They often anchor to larger debris while they feed or inch, worm-like, along substrates. Some are sessile, living inside tubes or gelatinous holdfasts and may even be colonial. Rotifers reproduce by parthenogenesis (in the absence of mates), producing clones (like cladocerans). Resting eggs (sometimes called zygotes) survive when a pond dries up. Bdelloid rotifers don’t produce resting eggs; they survive desiccation through a process called anhydrobiosis, contracting into an inert form and losing most of their body water. Embryos, juveniles and adults can undergo this process. The bdelloid withdraws its head and food and contracts its body into a compact shape called a tun; a generally unprotected dormant state that remains permeable to gases and liquids. Like Tardigrades (see below), Bdelloid rotifers can resist ionizing radiation because they can repair DNA double-strand breaks.

The long-term survival and evolutionary success of bdelloid rotifers in the absence of sex arises from horizontal gene transfer via DNA repair.

In my eco-novel A Diary in the Age of Water the limnologist Lynna visits her technician Daniel as he peers through a microscope and makes the observation of why the bdelloid rotifer is well-suited to climate change:

I bent to peer through the eyepiece at what turned out to be a pond sample in a Petri dish. Attached to a pile of detritus shivering in the current, several microscopic metazoans—rotifers—swung like trees in a gale; they were feeding. Their ciliated disk-like mouths twirled madly, capturing plankton to eat. Watching them reminded me of my early research days as an honours undergrad at Concordia University in Montreal. Probably Philodina, I thought; I had seen many during my stream research in Quebec.

“They’re the future,” Daniel said, looking up at me with a smirk as I straightened.

I raised my eyebrows, inviting him to elaborate, which he cheerfully did.

“They’re the future because of their incredible evolutionary success and their ecological attraction to environmental disaster.” He knew he’d piqued my interest. “These little creatures have existed for over forty million years, Lynna. Without sex! And they’re everywhere. In temporary ponds, moss, even tree bark. Bdelloid mothers that go through desiccation produce daughters with increased fitness and longevity. In fact, if desiccation doesn’t occur over several generations, the rotifers lose their fitness. They need the unpredictable environment to keep robust.” They incorporate genes from their environment: they acquire DNA transposons—mobile DNA—through HGT.”

—A DIARY IN THE AGE OF WATER

The bdelloid all-female populations have thrived for millions of years by maintaining a robust and diverse population through epigenetics and DNA repair during dormancy…The dormancy of all-female bdelloids is an elegant technique to ride out harsh conditions. The bdelloids can go dormant quickly in any stage of their life cycle, and they’re capable of remaining dormant for decades. They can recover from their dormancy state within hours when the right conditions return and go on reproducing without the need to find a mate.

Highly variable environments tend to support rare species: organisms that are uniquely equipped for change. These are the explorers, misfits, and revolutionaries who do their work to usher in a new paradigm. They carry change inside them, through phenotypic plasticity, physiological stress response mechanisms, or life history adaptations. Like bdelloid rotifers going dormant through anhydrobiosis. Or blue-green algae forming dormant akinete spores. In tune with the vacillations of Nature, epigenetics-induced adaptation is the only option for keeping up with rapid and catastrophic environmental change, not to mention something as gigantic as climate change. That’s why the bdelloid rotifers survived for millennia and will continue for many more. They adapt by counting on change.
