First Nation says Hydro misuse of river diversion destroying sturgeon population

A northern First Nation is calling on Manitoba Hydro to alter its use of the Churchill River diversion to protect a lake sturgeon population allegedly decimated by hydroelectric operations.

Tataskweyak Cree Nation Chief Doreen Spence said the culturally significant species is facing extinction on the river system without immediate intervention, 50 years after Manitoba built the diversion to send water to large power generating stations.

“The diversion has artificially altered the flow of the water… so much that the river is barely able to sustain life as it once did,” Spence told reporters in Winnipeg Thursday.

“Manitoba Hydro must operate the diversion in sync with the natural flow regime of the river for the sturgeon to survive.”

Funding shortfall undermines Canada’s ability to track diseases threatening wildlife, human health

The head of a national network that tracks the spread of wildlife diseases says a persistent funding shortfall is undermining Canada’s ability to detect and respond to emerging threats to biodiversity, agriculture and human health.

Damien Joly is the chief executive officer of the Canadian Wildlife Health Cooperative, a network of Canada’s five veterinary schools and the B.C. government’s Animal Health Centre. The CWHC works with federal, provincial and territorial governments to monitor wildlife diseases across the country.

In an interview with The Narwhal, Joly said the organization is “cash strapped across the board.”

“We do not have the resources we need to effectively monitor these diseases,” he said.

Manitoba enterprise at forefront in bolstering soil structure

Soil health has always been important to anyone who wants to grow plants that flourish but never more so than today. Soil degradation due to drought and extreme weather is a global problem that has a direct link to agricultural productivity and food security.

The status of soil health in Canada is not a concern limited to farmers and backyard gardeners. Scientists, policy makers and researchers are recommending urgent action to protect soils to safeguard the future of our food production.

In June 2024, following an 18-month study of soil conditions in Canada, the Standing Senate Committee on Agriculture and Forestry released the report Critical Ground: Why Soil is Essential to Canada’s Economic, Environmental, Human and Social Health. The report, which is based on testimony from more than 150 experts, concluded that soil in our country is at risk, with implications for food production, climate resilience and biodiversity.

Dale Overton takes soil health and its implications for fertility and food production seriously. His company, Overton Environmental Enterprises, manufactures several microbial products for large-scale agriculture as well as for the home gardener. Overton is deeply interested in regenerative farming practices and how biological amendments can benefit soil health, carbon sequestration and soil microbiomes, and boost growth rates and crop yields.

Who calls the shots on city land use?

Everybody thinks it, but no one wants to say it out loud — the fact that for decades, our city council and its administration have, to a large degree, been in thrall to the construction and development industries.

Body’s cellular makeup leads to big, existential questions

French science journalist and author Lise Barnéoud’s first book Hidden Guests is a fascinating, well-researched, atmospheric book on micro-chimerism — the presence of genetically distinct cells from one person circulating in another person.

Foods with healthy-sounding buzzwords could be hiding added sugar in plain sight

Many consumers feel pride in avoiding the glazed pastries in the supermarket and instead opting for “all natural” granola that comes packed with extra protein. Same goes for low-fat yogurts “made with real fruit,” organic plant-based milks and bottled “superfood” smoothies.

Buyer beware: Healthy grocery buzzwords like those often cover up an unhealthy amount of sugar.

Added sugars are difficult to quickly spot because many companies use clever marketing to distract consumers, said Nicole Avena, a professor of neuroscience and psychiatry at Mount Sinai Medical School and Princeton University who has studied added sugars.

Avena said while some health-forward brands know people are starting to become aware of the hazards of added sugars, "a lot of the bigger brands don’t worry so much about people’s health.”

U of M researchers studying whether genetic testing helps zero in on effective mental-health treatment meds

A team of University of Manitoba researchers is recruiting people seeking mental-health treatment for a study that could take the guesswork out of medication with the help of genetic testing.

The study will offer free pharmacogenomic testing — which predicts how a person may react to medications based on their genetic makeup — to 200 adults who are looking to start a new medication or switch their medication treating a mental-health issue.

“Someone with mental-health conditions, they (try) multiple medications, and sometimes it takes months or years to get to a point where those drugs work for them, or to have less side effects,” said Dr. Abdullah Maruf, the lead investigator on the study and assistant professor in U of M’s College of Pharmacy.

“Pharmacogenomic testing can find out how our body will respond to these kinds of medication.”

Killer whales and dolphins may be helping each other hunt of B.C. coast: new report

HALIFAX - Scientists have found evidence that two unlikely collaborators — killer whales and dolphins — may be helping each other find and feast on salmon off the coast of British Columbia.

Sarah Fortune, an assistant professor in oceanography at Halifax’s Dalhousie University said it would appear the massive fish-eating whales may be working with Pacific white-sided dolphins, which have been spotted eating the salmon chunks the killer whales produce.

She is a co-author of a paper published Thursday in Scientific Reports that found the two species appear to be working together while they forage.

Recordings picked up "this audible crunch as the whale bites down, then you see these fragments of fish that are released,” and then dolphins swim in to eat the pieces, Fortune said.

What happens when your immune system hijacks your brain

“My year of unraveling” is how a despairing Christy Morrill described nightmarish months when his immune system hijacked his brain.

What’s called autoimmune encephalitis attacks the organ that makes us “us,” and it can appear out of the blue.

Morrill went for a bike ride with friends along the California coast, stopping for lunch, and they noticed nothing wrong. Neither did Morrill until his wife asked how it went — and he'd forgotten. Morrill would get worse before he got better. “Unhinged” and “fighting to see light,” he wrote as delusions set in and holes in his memory grew.

Of all the ways our immune system can run amok and damage the body instead of protecting it, autoimmune encephalitis is one of the most unfathomable. Seemingly healthy people abruptly spiral with confusion, memory loss, seizures, even psychosis.

Author goes far and wide on quest to document all plants native to Manitoba

When Diana Bizecki Robson was growing up in Saskatoon during the 1970s, she enjoyed riding her bike to parks and riverbanks where she spent hours studying the diversity of wild plants and their pollinators.

After deciding to become a biologist, Bizecki Robson worked for a few years as an environmental consultant which allowed her to conduct plant surveys. But it was when the opportunity to work at the Manitoba Museum came along — in October 2003 — that she could finally pursue the type of field work and research she loves.

Today, Bizecki Robson is the curator of botany at the Manitoba Museum. She oversees a herbarium which holds over 50,000 specimens.

“One of the things I discovered as part of a collection assessment project that I did when I first got here was that the museum did not have a specimen of every single species of plant or fungus or lichen (from this province) in its collection,” said Bizecki Robson.

How Canada can regain its measles elimination status

TORONTO - Infectious disease experts say Canada's loss of measles elimination status shows how badly investment is needed in public health, rebuilding vaccine confidence and solving the primary care crisis.

On Monday, the Pan American Health Organization (PAHO) revoked the measles-free status Canada has had since 1998 because an outbreak of the virus across several provinces has lasted for more than a year.

Dawn Bowdish, an immunologist and professor at McMaster University, said cuts to public health funding, the lack of a national vaccine registry and a shortage of family doctors — all while misinformation about vaccines is circulating widely — have contributed to the rise of measles.

"There's no two ways about this. This will take money — a lot of money — and a lot of investment. And it will take a lot of political will," Bowdish said

Youth need addiction, mental health strategies: advocate

As politicians debate proposed legislation to detain adults in the throes of a meth psychosis for up to 72 hours, Manitoba’s children’s advocate wants to know how minors will be treated.

“When they talk about Bill 48 with respect to detaining intoxicated people for 72 hours or so, there is no youth-specific need addressed in that bill,” Sherry Gott said Wednesday.

The Protective Detention and Care of Intoxicated Persons Act would replace the Intoxicated Persons Detention Act, which allows for the 24-hour involuntary detention of people intoxicated by alcohol. It proposes 20 spaces for people to detox from the effects of drugs under medical supervision, but doesn’t say anything about youth.

The Manitoba Foster Parents Association echoed the advocate’s concern.

U of M research underscores importance of polar bears to future of Arctic

Polar bears are generous hunters whose leftovers feed many other animals, new research shows, casting the protected species as a major provider, not just a vulnerable predator in a province that attracts thousands of polar bear watchers every fall.

Arctic foxes, wolverines, eagles, hawks, gulls and even younger bears are among at least 11 species who feast on the prey left behind by polar bears. The latest study calculates the leftovers: 7.6 million kilograms per year in picked-over seal carcasses left on sea ice.

That’s a conservative estimate, said biologist and University of Manitoba PhD candidate Holly Gamblin, lead author of the study published Tuesday in the journal Oikos from the Nordic Ecological Society.

“A bunch of my co-authors are in that polar bear research world and have been thinking about investigating (this issue), knowing that it’s this really under-represented and under-studied component of the story, when we think about polar bears as apex predators,” said Gamblin, who has studied Arctic foxes. “They had had this idea for a while and I was just sort of in the right place at the right time.”

Prolonged drought stunts the renowned wild blueberry crop in the Maritimes

HALIFAX - This summer’s prolonged drought across Atlantic Canada has had a costly impact on wild blueberry growers in New Brunswick and Nova Scotia.

Donald Arseneault, general manager of the NB Blueberries industry group, says that as this year’s harvest was wrapping up, the total yield was believed to be 70 per cent less than the previous three-year average.

“This year has been tremendously dry and we haven't really seen this in a long time,” Arseneault said, adding that this year’s crop amounted to about 20 million pounds, down from the annual average of 68 million pounds.

The industry, which ships its product around the world, was also hurt by delays caused by the provincial government’s decision to temporarily shut down the harvest as it tried to deal with a growing number of wildfires that flared up amid tinder-dry conditions.

Chinese landscape architect Yu Kongjian among 4 killed in a plane crash in Brazil

RIO DE JANEIRO (AP) — The crash of a small plane in southwestern Brazil killed four people including Chinese landscape architect and urban planner Yu Kongjian, Brazilian authorities said Wednesday.

The accident happened late Tuesday during a landing attempt at a large farm about 100 kilometers (60 miles) from the municipality of Aquidauana in Mato Grosso do Sul state, firefighters said.

Yu, who was known for promoting ecologically sound development, was traveling with two Brazilian documentary makers, Luiz Fernando Feres da Cunha Ferraz and Rubens Crispim Jr., who were making a film about the Pantanal wetlands. All three were killed along with pilot Marcelo Pereira de Barros, authorities said.

Yu was know for developing the concept of “ sponge cities, ” with infrastructure that can absorb rainwater to mitigate flood risks and improve the urban climate.

Only moratorium can save moose population: MWF

The Manitoba Wildlife Federation is calling for a moose-hunt moratorium in two parts of the province after aerial surveys showed “significantly declining” numbers of the animal.

“The populations may never bounce back,” the federation’s Chris Heald said Tuesday.

The advocacy group representing sport hunters and anglers issued a news release calling for the complete closure of the fall moose hunt in Duck Mountain and Porcupine Forest. It follows Manitoba Conservation’s 2023 aerial survey results, which indicate “significantly declining moose populations” in the game-hunting areas in western Manitoba.

It wouldn’t be the first time for a moose conservation closure there. In 2011, licensed and Indigenous hunters supported a full closure of the moose hunt after a 2010 survey the showed moose population had fallen in both areas to 2,471 animals.

Another subdivision, another city problem

So, here we go again folks. We just get the protection of the Lemay Forest done and dusted and bingo, there’s another proposed subdivision for 23 homes on two-acre flood plain lots right across the Red River from the Lemay on the old Daman Farm site.

On World Rhino Day, South Africa marks progress but still loses a rhino daily to poachers

DINOKENG GAME RESERVE, South Africa (AP) — The Dinokeng Game Reserve in South Africa has a thriving rhino population, but their exact numbers and the details of the security operation that keeps them safe from poaching are closely guarded secrets.

They are the protocols that reserves with rhinos follow to ensure they're not the next target for poachers who still kill on average one rhino every day in South Africa for their horns despite decades of work to save the endangered species.

South Africa has the largest populations of both black and southern white rhinos of any country and sees itself as the custodian of the animals' future.

As conservationists mark World Rhino Day on Monday, South Africa remains in a constant and costly battle against poaching nearly 30 years after black rhinos were declared critically endangered, and more than a half-century since southern white rhinos were on the brink of extinction with just a few dozen left.

Province creates hunting buffer zone on Bloodvein First Nation

The Manitoba government is creating a buffer zone restricting where non-Indigenous hunters can harvest moose on Bloodvein First Nation’s traditional lands.

Manitoba Natural Resources and Indigenous Futures Minister Ian Bushie announced the change late Monday as moose season began for game hunting areas 17, 17A and 17B that includes the traditional areas of the First Nation, located 285 kilometres north of Winnipeg.

The community, which established a check stop to prevent illegal drugs and contraband from entering the First Nation, warned “outside hunters” on social media weeks ago that they’re not welcome to take moose on their traditional lands.

The Manitoba Wildlife Federation has questioned the First Nation’s authority to block licensed hunters with a moose tag from the area and called on the provincial government to intervene.

Very hungry caterpillars very good for biodiversity

Widely considered a pest and a scourge, a leaf-chomping defoliator dedicated to decimating crops, boring into buds and biting down blossoms as it works to satiate its inexhaustible appetite, a new nature documentary reveals there’s more to the much-maligned caterpillar than meets the eye.

The larval creature takes centre stage in Winnipeg filmmaker Jeff McKay’s documentary feature The Extraordinary Caterpillar.

His hour-long film takes viewers on a journey to understanding why the famously “very hungry caterpillar” is a key player in maintaining biodiversity.

“Caterpillars are right at the centre of the food chain, they are key to the food chain working as it should,” McKay says.
