SALT LAKE CITY — When employees at a local eating disorder clinic asked a teenage resident why she was refusing to eat, the teen lifted up her shirt and pointed at her stomach.

“I would rather die than have tummy rolls,” she said.

Christine Parks, a care technician who witnessed the interaction at Utah’s Center for Change, has gone through recovery for eating disorders and felt flooded with emotion — and protectiveness.

She knew that the girl’s statement was not an exaggeration. Eating disorders have the highest mortality rate of any mental illness, and they are impacting teenage girls now more than ever.

Experts say that since the COVID-19 pandemic began, there have been documented increases in eating disorders in the United States, Canada, Australia, Europe and the Middle East.

According to a study from the Centers for Disease Control and Prevention released last week, emergency room visits for eating disorders doubled among 12- to 17-year-old girls nationwide since the pandemic began. And those are just the cases that are life-threatening enough to warrant emergency admission during a pandemic.

The National Eating Disorders Association has reported a 107% increase in calls to their help line since March 2020.

Researchers have found a number of potential reasons for the growing number of eating disorder cases, including having to eat meals in front of others, having less-structured meal times, exercising at home using videos on social media and apps, video conferencing and increases in stress levels.

Multiple studies have shown that the heightened attention to weight gain on social media during lockdown led people to increase their physical activity to an excessive level out of fear. One 2021 study from the University of Connecticut Rudd Center for Food Policy and Obesity found that over 50% of teenagers saw social media content that stigmatized weight gain during that time period.

Although no organizations are quantifying exactly how many eating disorder cases there are in Utah, the demand for treatment has skyrocketed since 2020.

“Every person I know is full or has a waitlist and has closed their waitlists, including dietitians and people working at hospitals. I have colleagues who prefer not to treat eating disorders, and it’s not an option anymore,” said Dr. Corinne Hannan, a psychologist specializing in eating disorders and assistant clinical professor at Brigham Young University.

“From my chair, it’s not showing any decline. Quite the opposite,” she added.

A culture of perfection

When a former college track athlete, who asked to remain anonymous for privacy reasons, arrived at the Utah university a couple of years ago, she noticed a pattern in the people around her that she said she didn’t see nearly as often in her home state.

She said it was completely normal for her friends and teammates to eat foods they deemed unhealthy or fattening and then compensate by “running it off” for miles and miles or exercising excessively. In fact, she said this behavior was rewarded and encouraged. She said her coach at the time even told her to lose 3 to 5 pounds, even though she was regularly exercising and lifting weights.

Excessive or compulsive exercise as a form of purging is also known as anorexia athletica or exercise bulimia, but it is not a recognized clinical eating disorder in the Diagnostic and Statistical Manual of Mental Disorders. However, the National Eating Disorder Association website states that compulsive exercise can be a symptom of disordered eating or a recognized eating disorder, and the symptom itself can lead to bone density loss, loss of menstrual cycle in women, and other severe medical conditions, some of which can be life-threatening.

Hannan explained that it was impossible to find data on how many Utahns are dealing with eating disorders because the data does not exist. There’s not enough research being done and not enough funding for researchers to pursue it.

The former athlete’s mother, Michelle, who runs an international Facebook group for family members of people with eating disorders, expressed that another problem gathering this data is that everyone has different definitions of what recovery means. So local treatment centers, which go largely unregulated, might not report accurate recovery rates.

Every person interviewed for this story mentioned a culture of toxic perfectionism that applies to appearance.

Hannan speculated that the high rates of perfectionism she sees in clients and students in Utah occur because of an association with physical perfection and religious worthiness or an unconscious need to stand out as the most perfect in a homogenous crowd of other white, slim people who make up the majority demographic of the state.

No matter the reason, it is impossible to drive down a freeway without coming across billboards telling you to change your appearance through plastic surgery, cool sculpting or dieting, Park said.

“It’s definitely a beauty-saturated place,” she continued. “Hair extensions, fake eyelashes, spray tans: It’s almost like the expectation is that everyone should have that. … How did we get here? How did Utah’s beauty ideals become like this? It’s so preventable.”

No specific look or size

Although the reported number of hospitalizations is growing specifically among adolescent girls, eating disorders do not pertain only to people of a certain look or size.

During Parks’ work at Center for Change, she has come across grandmothers who have had an eating disorder for 40 years, military personnel, athletes, mothers, and people of all ages and backgrounds.

“You can never tell based off looking at someone,” she said. “It gives me so much more compassion for anyone who struggles with food and body issues because it’s truly an invisible disease. Everybody is worthy of getting help.”

Multiple studies show that marginalized populations like people of color and members of the LGBT community have higher rates of developing eating disorders. And children are far from immune, as some Americans are putting children on diets at younger and younger ages.

“I wish the average person understood that eating disorders are not something you can diagnose with your eyes. They are underdiagnosed and underrepresented due to misinformation and normalization and promotion of disordered eating of society,” Hannan said.

Anyone of any ethnicity, gender, size, age or ability could possibly have an eating disorder, she added, but the biggest predictor of youth developing an eating disorder is dieting.

Effects of social media

Parks was 15 years old when she first started developing orthorexia, an eating disorder characterized by an obsession with healthy eating. She didn’t see it as a problem. After all, she told herself, she was just trying to be healthy.

This was also when Instagram was fairly new, and it became the breeding ground for her issues with food.

“I 100% used it as a resource to figure out how to lose weight. I remember looking up strategies of what to do when I’m hungry instead of eating,” she said.

Now, after recovering from her years of being trapped in a cycle of heavily restrictive eating — becoming nutritionally and calorically deprived, binging secretly and resetting weight loss goals in shame — she runs an account specifically dedicated to eating disorder recovery on the same platform that encouraged her illness: Instagram.

When she was an undergraduate at Brigham Young University, all-consuming thoughts of food terrorized her during 90% of her waking hours. She began to isolate herself from everyone, even planning her walks across campus to avoid crowds so she wouldn’t be seen because she “didn’t feel worthy or valuable as a person until (she) was thin enough.”

In 2019, she attended a meeting on campus that addressed disordered eating and eating disorders and promoted intuitive eating, or making peace with food and relying on your body’s cues to decide what and when to eat.

As Parks began to work with a dietitian and a therapist to get her life back, she came across a quote from Dr. Thema Bryant, a psychologist and minister, that inspired her to write about the eating disorder she had kept hidden for so many years.

“When you shatter the shame and begin sharing your story, a thousand chains will fall off people you never met,” Bryant wrote.

Parks wrote out her story in a blog post titled, “The eating disorder that no one talks about.” She took a deep breath and clicked “publish.” The response from her community was immediate.

“Messages upon messages came pouring in from people I know and people I didn’t know,” she said.

Later that year, she decided to start an Instagram account called @ed_stories. She shared 120 recovery stories within the first year from people across the country and abroad.

“Advocating lights my soul on fire,” Parks said, and her experience running the account has shown her social media’s “incredible capacity for good.”

“Now I follow a million therapists and dietitians in the eating disorder space. You can curate your feed for recovery,” she said. “But it does need to be heavily regulated and monitored.”

The National Eating Disorder Association website states that 7 out of 10 women and girls report a decline in body confidence attributed to pressure to attain society’s unrealistic beauty standards.

In October, Frances Haugen, a Facebook data scientist turned whistleblower, leaked internal Facebook studies that showed that Instagram harmed teenagers. One study, in particular, showed that 17% of teenage girls reported that the app made eating disorders worse. Haugen testified before Congress on Oct. 5, 2021, stating, “Facebook knows that they are leading young users to anorexia content.”

When Hannan heard this news, she was disappointed and angry but unsurprised.

“There is a substantial body of research showing how social media can contribute to disordered eating and body negativity. The issue with Facebook is a continuation and magnification of an already existing problem,” she said.

It is almost impossible to use social media without coming across millions of money-making accounts that invent a flaw, make you feel insecure, and then sell you a solution, Hannan explained. And youth are using social media for hours as a part of their daily routine.

“Companies with all this power and influence are preying on the most vulnerable of us: teens and children. There’s no accountability and no ethics. It continually breaks my heart,” she said.

However, she also believes social media can reach and connect people worldwide in an unprecedented way and share accurate information. But doing so in a way that competes with the multibillion-dollar diet industry takes a lot.

Although she hasn’t done publishable research on curating a social media feed, Hannan has found that if she only followed and interacted with very specific accounts, she could limit the amount of damaging material she was exposed to.

“I wouldn’t be surprised if curating a media feed that supports your recovery is as powerful as being exposed relentlessly to hours and hours of images,” Hannan said, and she’s optimistic that people with the time and team will create content to make a better world.

Parks also said she doesn’t recommend blocking teens from accessing social media. Instead, she suggests taking breaks, paying attention to the research being done on social media consumption, educating teenagers about the risks, unfollowing any accounts that promote unhealthy behaviors or comparison, and following specialists and doctors involved in eating disorder recovery and intuitive eating.

Recovery is possible

The biggest point every interviewee emphasized was that recovery from eating disorders is absolutely possible.

Hannan’s clients sometimes refer to the journey to recovery with pop culture references, like Frodo destroying the ring in “Lord of the Rings” or Ron Weasley having to face all his worst fears before destroying a horcrux in the Harry Potter movies.

Michelle recommends that parents and supporters help their loved ones with eating disorders find evidence-based treatment that will lead to long-term recovery.

Rewiring the brain doesn’t happen overnight, but for Parks, recovery looks like getting her life back: dating, creating and deepening relationships with friends, being present with family, pursuing a career, and living a fulfilling and happy life.

She still struggles occasionally, but she really does feel as though a thousand chains have fallen off her since she began recovery. She is miraculously, gloriously free.

Norway bans breeding Cavalier King Charles Spaniels, bulldogs

They may look cute, but Norway has ruled they’re a product of cruelty — and they’re no longer allowed to be bred.

On Monday, Norway’s Oslo District Court made a unanimous, landmark ruling that breeding bulldogs and Cavalier King Charles Spaniels are a violation of the Norwegian Animal Welfare Act section 25 and will no longer be tolerated. 

The ruling was prompted by a case brought in November 2021 by Animal Protection Norway out of concern for the dog breeds’ numerous, critical health issues.

“The man-made health problems of the bulldog have been known since the early 20th century. This verdict is many years overdue,” said Åshild Roaldset, the CEO of Animal Protection Norway in a post published by the group following the ruling. “For several decades, sick dogs have been bred in violation of Norwegian law. Our dogs [have] been victims of systematic and organized betrayal of our four-legged friends. Today it has been confirmed that this is illegal.”

The ruling is not a blanket ban on the breeds, however, but a nuanced “legal framework for animal breeding,” noted lawyer Emanuel Feinberg in the post. Thus, cross-breeding of the beloved — if often sickly — dog types is still possible and permitted.

“A conviction does not imply a ban on serious breeding of Bulldog or Cavalier, as serious and scientifically based cross-breeding could be a good alternative,” the judgment stated. The nation has the infrastructure to make more humane cross-breeding a reality, Animal Protection Norway added, noting the technology also exists.

To aid in the transition to better breeding tactics, the Animal Protection Norway has proposed more regulated use of temperament, traits and health data in breeding, as well as the use of chip marking. Without such traceability, “it is impossible” for dog breeding to be effectively supervised, Roaldset added. 

“This is a day of celebration for our dogs! The Animal Welfare Act is intended to protect animals from the irrational actions of humans, and it has done so today. This is about the dogs’ right to feel good,” said Roaldset.

Scientists just learned what makes dogs huge or tiny — and it long predates selective breeding

Sometimes it is difficult to believe that all dogs are related. How can the tiny chihuahua be from the same species as the massive Great Dane? A male beagle is usually between 14 and 16 inches tall; a male English Mastiff can be as tall as 28 to 36 inches. One does not see similarly massive size disparities in other species, much less humans. (This would be the equivalent of adult humans regularly varying from two feet to six feet tall.)

Clearly there is something in the canine genetic code that explains this, just as doggie DNA has unlocked secrets regarding sled dogs, brachycephalic heads and self-domestication. For years scientists have attempted to solve the biological puzzle that can cause up to 40-fold size differences between dogs — and now, thanks to authors of a recent paper published in the journal Current Biology, we have the answer.

It all starts with a gene called IGF1, which regulates growth hormones and has long been suspected of playing a role in canine size variation. Scientists at the National Human Genome Research Institute of the National Institutes of Health compared variations in the region around that gene in dogs and wild canids with every imaginable body size. After doing so, they discovered that two alleles (or versions) of a single variant in a strand of long non-coding RNA, one that plays a role in controlling IGF1 protein levels. If dogs had only one copy of each allele, they tended to be medium-sized, but if they had two copies they would either weigh less than 15 kilograms (33 pounds) or more than 25 kilograms (55 pounds). That depended on which allele they had — and this further demonstrates that these genetic quirks are responsible for the drastic size disparities in dogs.

RELATED: Similar to humans, dogs’ personalities change over their lifetimes: study

Even more intriguingly, these alleles were present in wolves more than 50,000 years ago — long before humans domesticated them. Scientists in England and Germany found that the mutation existed in DNA from 54,000-year-old Siberian wolf fossils. Every modern canid species, from coyotes and foxes to jackals and wolves, has this mutation in their DNA.

“This is tying together so much about canine domestication and body size, and the things that we think are very modern are actually very ancient,” American geneticist Elaine Ostrander, one of the corresponding authors on the paper, said in a statement. She also referred to the fact that, although canids have always had the genetic tools to produce animals with wildly differing sizes, this did not happen on a widespread basis until the last 200 years — when humans began creating modern dog breeds.

“It’s as though Nature had kept it tucked in her back pocket for tens of thousands of years until it was needed,” Ostrander explained. While identifying the mutations responsible for size variation is a big deal, Ostrander told Live Science that there is still a lot more work to be done.

“The next step is to figure out how all the proteins produced by these genes work together to make big dogs, little dogs and everything in between,” Ostrander said.

Although there has not been as much controversy over breeding small dogs as there has been over breeding dogs with flat faces, they are still prone to health issues like intervertebral disk disease and tracheal collapse. They are also perceived as being more prone to behavioral issues, and scientists are still unclear as to why that seems to be the case.

“It could be a genetic association with small body size,” Dr. James Serpell, an animal behavior expert at the University of Pennsylvania, told Salon by email in August. “It could be because little dogs feel more threatened and defensive than bigger dogs and are therefore more likely to react aggressively. And it could be that the owners of small dogs are more protective of their pets and consequently fail to socialize them properly when they are young and impressionable. Or maybe it’s a combination of all three.”

Birds Use Earth’s Magnetic Field For ‘Stop Signs’ When They Migrate

Thanks to a combination of sensing the Earth’s magnetic field through vision and an in-built compass that allows them to orient themselves according to magnetic intensity, migratory birds don’t have much trouble finding their way.

 

Those biological gadgets, known as magnetoreception, allow birds to not only know which direction to head in on their first outbound migration but to know how to return to their nesting sites with extreme accuracy, often within meters of their original natal site.

To figure out how birds know when to stop, scientists investigated if birds may also be using cues from Earth’s magnetic field to locate their breeding sites more accurately.

The cues could be the magnetic inclination – the dip angle between Earth’s magnetic field and Earth’s surface – or the magnetic intensity, the overall strength of Earth’s magnetic field. 

Earlier research suggested similar ideas as a means for birds to return to their desired flight paths if an extreme weather event had sent them off course. 

The new study used data from 17,799 ringing recoveries (marked birds) from 1940 to 2018 to investigate if and how the Eurasian reed warbler (Acrocephalus scirpaceus), a trans-Saharan migratory songbird, used magnetic information to return to its nesting site.

If these birds actually use cues from Earth’s magnetic field to locate their original breeding site, then the researchers reason that yearly variations in Earth’s magnetic field should be reflected in gradual positional changes of the bird’s nesting areas.

 

“Because Earth’s magnetic field shifts slightly year by year, the magnetic parameter values characteristic of an individual’s natal or breeding site will exist in a different location the following year,” the authors explain.

“Hence, if birds used magnetic parameters to determine the location of their natal or breeding site, we would expect that positional changes between years would reflect year-on-year changes in the location of specific magnetic parameters.”

Findings from the study point to magnetic inclination as the primary magnetic cue for the birds when relocating their breeding site, with specific inclination parameters signaling as a sort of ‘stop sign’. 

The authors suggest that the birds ‘learn’ the inclination angle before departing their breeding sites.

“We hypothesize that this is consistent with inclination acting as a uni-coordinate stop sign: Birds could recall their natal or breeding location using only one coordinate dimension, if used alongside a compass bearing linking the wintering and breeding sites,” state the authors. 

Using magnetic inclination as the primary cue for relocating their breeding site makes sense, according to the authors, because it has the most stable year-on-year variation compared to other potential magnetic cues. It provides migratory birds with a more reliable sign that they have reached a desirable location.

 

“Additionally, other magnetic gradient–derived positions move further with secular variation, which makes the proposed mechanism relatively robust. The position of the natal site as estimated using inclination and declination as a bicoordinate map would move, on average, 18.5 km (11.5 miles) between years; as estimated using intensity and declination, 20.4 km; and as estimated using intensity and inclination, 98.2 km,” state the authors.

“By contrast, the location of the breeding site denoted using inclination as a stop sign moves only 1.22 km between years. We suggest that, by remembering breeding location relative to the most stable cue and referencing it alongside a compass bearing, the proposed strategy minimizes the impact of secular variation.” 

In fact, scientists found that birds recovered for use in the study closer to the site predicted by the inclination stop sign model than they were to their natal or breeding site, suggesting the birds may even prioritize the bio coordinate clues of magnetic inclination over even their breeding site. 

Overall, it appears that by harnessing a number of biological mechanisms related to the parameters determined by Earth’s magnetic field, migratory birds are able to successfully navigate and find the crucial environments needed for their continued survival.

The research was published in the journal Science.

A Massive Icefish Breeding Colony Existed In Secret In Antarctica — Until Now

A polar research exploration has discovered a previously unknown breeding colony of millions of fish in an icy Antarctic sea.

Believed to be the world’s largest known fish breeding ground, the expanse of about 60 million Jonah’s icefish nests stretches across 92 square miles of the Weddell Sea floor, according to The New York Times.

Adult icefish guard thousands of eggs.

Icefish have no red blood cells ― which gives them transparent blood ― and skulls that you can see through. Their clear blood also contains a special protein that stops it from freezing.

The scientists who made the discovery, researchers from Germany’s Alfred Wegener Institute aboard the RV Polarstern, weren’t looking for icefish nests in particular. But when they came across the nest site, they knew they’d found something special.

“I’d never seen anything like it in 15 years of being an ocean scientist,” researcher Dr. Autun Purser told CNN. “After that dive, we emailed the experts on shore who know about fish like this. They said, yep, this is pretty unique.”

A typical nest had around 1,500 to 2,000 eggs, New Scientist reports. Purser told the publication that it’s unclear how many of those eggs ultimately hatch and survive, and that in general, a lot about icefish is still unknown.

Most of the nests were guarded by an adult fish, but in some cases, one fish guarded multiple nests. Still other nests were empty, or contained the carcass of a fish who died at its post. Fish who died in the middle of the nest field tended to just rot in place, while those who died closer to the edges were scavenged by animals like starfish and octopuses.

Another animal that enjoys dining on the icefish is the Weddell seal, a plump, carnivorous mammal that can dive up to 2,000 feet into the ocean.

The researchers who discovered the icefish nests took a look at satellite tracking data on the seals and found that the nest site is a major destination for Weddell seal dives.

“They’re having a nice dinner,” Purser told the Times.

Massive icefish breeding colony found in Antarctica

Scientists have discovered a massive breeding colony of icefish in Antarctica’s southern Weddell Sea.

The big picture: Groups of up to 60 icefish nests have been spotted before, but researchers have now found an estimated 60 million active nests, which is believed to be the largest ever seen.

Details: Scientists were towing a camera behind their research vessel early last year to survey the seafloor when they made the surprising discovery.

  • “We found fish nest after fish nest for four hours,” says Autun Purser, a deep-sea ecologist at the Alfred Wegener Institute in Bremerhaven, Germany. “Nothing but fish nests.”
  • The colony spans an estimated 240 square kilometers (about 93 square miles), the researchers reported in the journal Current Biology.
  • The majority of the nests had one male icefish guarding the eggs.

Why it matters: The researchers think the icefish (Neopagetopsis ionah) could be using the warmer waters in the area to navigate to the breeding colony.

  • Purser says it is likely the icefish are an important food source for Weddell seals that populate the sea ice and are known to dive in the area.

What’s next: The scientists left cameras in the water to photograph the nests four times each day for the next three years.

  • They’re interested in capturing more details about the nests — including whether the eggs hatch at the same time and if the location of the nests changes — to understand how the massive colony delivers nutrients to the unique ecosystem.
  • “The deep sea and under ice environment are not barren of life,” Purser says. The colony is “a huge hidden ecosystem and it must support and influence neighboring ecosystems.”

Researchers find the world’s largest fish breeding ground in ‘spectacular discovery’

A massive fish colony found below the ice covering Antarctica’s Weddell Sea is the largest known breeding ground of fish ever discovered, according to new research published in the journal Current Biology. 

In February 2021, the German research vessel Polarstern was surveying the seafloor using a towed camera system that reaches more than 1,000 feet below the sea’s surface, and transmits images up to the deck to be viewed by researchers onboard.  

What scientists viewed on the ship’s monitors was an unexpected find: a huge number of icefish nests that appeared to go on forever in all directions.

“The idea that such a huge breeding area of icefish in the Weddell Sea was previously undiscovered is totally fascinating,” Autun Purser, a deep-sea biologist at the Wegener Institute, Helholtz Center for Polar and Marine Research and lead author of the study, said in a statement. 

 “After the spectacular discovery of the many fish nests, we thought about a strategy on board to find out how large the breeding area was — there was literally no end in sight,” Purser added.  

The camera recorded more than 16,000 nests during a four-hour dive. Researchers said mapping of the area suggests the total number of fish nests is about 60 million stretched across 92 square miles of seabed, which would make it the largest such breeding colony ever discovered.  

Researchers viewed round fish nests on the seafloor about every 10 inches that measured about 6 inches deep and 29 inches in diameter. Several types of nests were observed, including active nests that contained 1,500 to 2,500 eggs guarded by adult icefish, nests that contained only eggs and empty nests. The nests were carved into the mud by notothenioid icefish.  

Camera systems have been deployed to monitor the colony until a research vessel returns to the region later this year to study the vast breeding ground.

Massive Icefish Breeding Colony With 60 Million Nests

Researchers detect around 60 million nests of Antarctic icefish over a 240 square kilometers area in the Weddell Sea.

Near the Filchner Ice Shelf in the south of the Antarctic Weddell Sea, a research team has found the world’s largest fish breeding area known to date. A towed camera system photographed and filmed thousands of nests of icefish of the species Neopagetopsis ionah on the seabed. The density of the nests and the size of the entire breeding area suggest a total number of about 60 million icefish breeding at the time of observation. These findings provide support for the establishment of a Marine Protected Area in the Atlantic sector of the Southern Ocean. A team led by Autun Purser from the Alfred Wegener Institute publish their results in the current issue of the scientific journal Current Biology.

The joy was great when, in February 2021, researchers viewed numerous fish nests on the monitors aboard the German research vessel Polarstern, which their towed camera system transmitted live to the vessel from the seabed, 535 to 420 meters below the ship, from the seafloor of the Antarctic Weddell Sea. The longer the mission lasted, the more the excitement grew, finally ending in disbelief: nest followed nest, with later precise evaluation showing that there were on average one breeding site per three square meters, with the team even finding a maximum of one to two active nests per square meter.

The mapping of the area suggests a total extent of 240 square kilometers, which is roughly the size of the island of Malta. Extrapolated to this area size, the total number of fish nests was estimated to be about 60 million. “The idea that such a huge breeding area of icefish in the Weddell Sea was previously undiscovered is totally fascinating,” says Autun Purser, deep-sea biologist at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) and lead author of the current publication. After all, the Alfred Wegener Institute has been exploring the area with its icebreaker Polarstern since the early 1980s. So far, only individual Neopagetopsis ionah or small clusters of nests have been detected here.

The unique observations are made with a so-called OFOBS, the Ocean Floor Observation, and Bathymetry System. It is a camera sledge built to survey the seafloor of extreme environments, like ice-covered seas. It is towed on a special fiber-optic and power cable normally at a speed of about one half to one knot, about one and half meters above the seafloor. “After the spectacular discovery of the many fish nests, we thought about a strategy on board to find out how large the breeding area was — there was literally no end in sight. The nests are three quarters of a meter in diameter — so they are much larger than the structures and creatures, some of which are only centimeters in size, that we normally detect with the OFOBS system,” Autun Purser reports. “So, we were able to increase the height above ground to about three meters and the towing speed to a maximum of three knots, thus multiplying the area investigated. We covered an area of 45,600 square meters and counted an incredible 16,160 fish nests on the photo and video footage,” says the AWI expert.

Based on the images, the team was able to clearly identify the round fish nests, about 15 centimeters deep and 75 centimeters in diameter, which were made distinct from the otherwise muddy seabed by a round central area of small stones. Several types of fish nests were distinguished: “Active” nests, containing between 1,500 and 2,500 eggs and guarded in three-quarters of the cases by an adult icefish of the species Neopagetopsis ionah, or nests which contained only eggs; there were also unused nests, in the vicinity of which either only a fish without eggs could be seen, or a dead fish. The researchers mapped the distribution and density of the nests using OFOBS’s longer-range but lower-resolution side scan sonars, which recorded over 100,000 nests.

The scientists combined their results with oceanographic and biological data. The result: the breeding area corresponds spatially with the inflow of warmer deep water from the Weddell Sea onto the higher shelf. With the help of transmitter equipped seals, the multidisciplinary team was also able to prove that the region is also a popular destination for Weddell seals. 90 percent of the seals’ diving activities took place within the region of active fish nests, where they presumably go in search of food. No wonder, the researchers calculate the biomass of the ice fish colony there at 60 thousand tonnes.

With its biomass, this huge breeding area is an extremely important ecosystem for the Weddell Sea and, according to current research, likely to be the most spatially extensive contiguous fish breeding colony discovered worldwide to date, the experts report in the publication in Current Biology.

German Federal Research Minister Bettina Stark-Watzinger said: “My congratulations to the researchers involved on their fascinating discovery. After the MOSAiC expedition, German marine and polar research has once more reaffirmed its outstanding position. German research vessels are floating environmental research laboratories. They continue to sail the polar seas and our oceans almost non-stop, serving as platforms for science aimed at generating important findings to support climate and environmental protection. Funding by the Federal Ministry of Education and Research (BMBF) provides German marine and polar research with one of the most state-of-the-art research vessel fleets worldwide. This discovery can make an important contribution towards protecting the Antarctic environment. The BMBF will continue to work towards this goal under the umbrella of the United Nations Decade of Ocean Science for Sustainable Development that runs until 2030.”

For AWI Director and deep-sea biologist Prof. Antje Boetius, the current study is a sign of how urgent it is to establish marine protected areas in Antarctica. “This great discovery was enabled by a specific under-ice survey technology we developed during my ERC Grant. It shows how important it is to be able to investigate unknown ecosystems before we disturb them. Considering how little known the Antarctic Weddell Sea is, this underlines all the more the need of international efforts to establish a Marine Protected Area (MPA),” Antje Boetius classifies the results of the study, in which she was not directly involved. A proposal for such an MPA has been prepared under the lead of the Alfred Wegener Institute and is defended since 2016 by the European Union and its member states as well as other supporting countries in the international Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

Antje Boetius adds: “Unfortunately, the Weddell Sea MPA has still not yet been adopted unanimously by CCAMLR. But now that the location of this extraordinary breeding colony is known, Germany and other CCAMLR members should ensure that no fishing and only non-invasive research takes place there in future. So far, the remoteness and difficult sea ice conditions of this southernmost area of the Weddell Sea have protected the area, but with the increasing pressures on the ocean and polar regions, we should be much more ambitious with marine conservation.”

New Zealand Kākāpō Are Genetically Strong, Despite Millennia of Inbreeding

Flightless, ungainly, and famously bad at sex, the critically endangered kākāpō of New Zealand—the world’s heaviest parrots—are in surprisingly good genetic health after 10,000 years of inbreeding, according to new research.

An international team of geneticists, biologists, and ecologists recently looked at 49 of the birds’ genomes to understand how the small populations were faring genetically, given their near-extinction 30 years ago. The team came away surprised at how the species, which now totals just over 200, has avoided the kind of damaging mutations that plague other animals on the brink of extinction. Their research is published today in Cell Genomics.

“The main finding of this study is that, even though kākāpō are one of the most inbred and endangered bird species in the world, it has much fewer harmful mutations than expected,” said Nicolas Dussex, lead author of the paper and a researcher at the Centre for Palaeogenetics and Stockholm University, in an email to Gizmodo. To explain this unexpected result, Dussex’s team suggests a counter-intuitive genetic phenomenon called purging, by which inbred populations end up having fewer harmful mutations in their genetic code rather than more.

“It seems that one factor favouring purging is the speed of the decline and the rate of increase of inbreeding,” Dussex added. “If inbreeding increases very rapidly, a large number of harmful mutations will be exposed to natural selection in a very short timespan … Conversely, if inbreeding increases gradually, harmful mutations are exposed little by little, over a larger number of generations and not in all individuals at the same time.” In other words, because kākāpō inbred over 10,000 years isolated on the islands of New Zealand, a fatal population crash due to genetic corruption never happened.

Kākāpō do not look like survivors. The bird, also called an owl parrot, fits into the same category as giant pandas and quokkas as creatures whose survival seems purely aesthetic, at least to the untrained eye. Kākāpō like to eat fruit, especially the rimu fruit, nest in ground-level shelters, and can live quite long, perhaps up to 80 years. Kākāpō are often infertile and sometimes have poor judgment—one kākāpō named Sirocco famously tried to mate with a wildlife photographer’s head. 

Hunted by invasive mustelids (which were introduced by humans to cull booming rabbit populations), kākāpō easily could have followed in the footsteps of the similarly ground-bound dodo, but surviving populations of the birds were moved to predator-free islands around New Zealand in the 1980s. Since then, attempts to reduce inbreeding and maintain genetic diversity in the minuscule population have been paramount.

“We show that the single male survivor from the mainland, Richard Henry, has more harmful mutations than Stewart Island birds,” said paper co-author Love Dalén, a researcher at the Centre for Palaeogenetics and the Swedish Museum of Natural History, in a statement. “Therefore, there could be a risk that these harmful mutations spread in future generations.”

Richard Henry the kākāpō was found in Fiordland in southwestern New Zealand, and his genetic diversity and virility were imperative in pulling the birds back from extinction. At the same time, though, Henry’s DNA harbors more harmful mutations than kākāpō from Stewart Island. (Richard Henry is named after a human who devoted much of his life at the turn of the 20th century to saving the species. Henry the human’s work has been resumed by a handful of New Zealand conservationists, many of whom co-authored the paper published today.)

The kākāpō’s genetic success story could be contrasted with that of the Isle Royale wolves, whose population of about 50 in 2011 plummeted to just two in 2016 after a new individual messed with the genetics of the already dangerously inbred group. A study of that situation, published last year in Evolution Letters, indicated that sometimes pushing high genetic diversity too quickly in a group with low genetic diversity can cause the population to collapse.

It’s also, perhaps, a warning for the kākāpō, as the bird is hardly out of the proverbial woods and, genetic diversity aside, has to worry about the predatory stoats and weasels that prowl its territory. The recent research will help to refine the breeding program approach, Dussex said, and new island populations could be established now that researchers have a better understanding of how all those in the current population relate.

If researchers manage to keep the kākāpō population genetically healthy, it’d be a big win in the battle for the animal’s survival. There are many threats ahead, but the portly green bird has a chance.

‘Ankle biter’ mosquito breeding on the rise throughout Southern California

GARDEN GROVE, Calif. (KABC) — The Orange County Mosquito and Vector Control District is seeing a greater number of “ankle biter” mosquitoes this summer.

Lora Young, the director of communications for OCMVCD, said these pesky pests are mostly noticeable because they’re the ones causing pain throughout Southern California.

“Especially with the Aedes mosquito. They’re a very aggressive day-biting mosquito and they prefer to bite people where our other mosquitoes prefer to bite birds,” Young said.

Young said numbers for the southern house mosquito – that’s the one able to carry West Nile Virus – are trending about average when compared to the last five years.

So far, there are no reports of West Nile Virus in O.C. this season, but the L.A. County Department of Public Health reported its first human case last Tuesday.

The Aedes, or ankle biters, also known as container breeders, are breeding more than ever.

Young said it’s because they’re invasive.

Their entry into the U.S. was traced back to a shipping container in 2015, and because they’re not native here, they really don’t have any natural predators to control them. That combined with the heat is a recipe for breeding disaster.

“In this weather right now, with the heat they can turn from egg to adult in seven days,” Young said.

To avoid getting bit, Young recommends an EPA-registered repellent with DEET, picaridin or oil of lemon eucalyptus and eliminating water sources which they need to breed.

“We call them container breeders because they prefer to breed in small containers, yard drains, flower pot saucers, any plant holding water, like bromeliads, lucky bamboo – things like that,” Young said.

Staff with the agency puts out more than a 100 traps a week throughout the county to track the number of mosquitoes and test them for diseases.

Anyone who feels there’s an issue on their property can call vector control. They’ll send out inspectors to take a look.
