How common swifts migrate, new research

This May 2020 video is called COMMON SWIFT – Apus apus – Foraging.

From Lund University in Sweden:

Rare pattern observed in migrating common swifts

September 15, 2020

Summary: Compared with other migratory birds, the common swift follows a very unusual pattern when it migrates from the breeding areas in Europe to its wintering locations south of the Sahara. This is what researchers have observed in a major eleven-year international study of the birds.

“Our study is very significant for understanding how organisms, in this case the common swift, can migrate from one part of the world to another, where access to food is much better at a given time,” says Susanne Åkesson, professor at Lund University and principal investigator of the study.

Common swifts that nest in Sweden and northern Europe arrive in sub-Saharan Africa four to six weeks later than the swifts that nest in southern Europe. By that time, the southern European swifts have already migrated even further south on the African continent. Hence the term chain migration, as opposed to the much more common pattern known as leap-frog migration, in which the populations that arrive first in a location claim the territory and occupy it, forcing populations that arrive later to leap-frog over the occupied area and fly further.

The common swift is the most mobile terrestrial bird in the world. When it is not breeding, it spends 24 hours a day airborne, for a total of ten months a year. According to the researchers, this has contributed to the species developing its unique migration pattern. Life in the air means that the swifts need a steady supply of energy and therefore food in the form of insects. This explains why the southern European populations migrate even further south in Africa when food availability increases there in the second half of the wintering period. It also explains why they are larger than their relatives from northern Europe. Quite simply, they make sure always to be in the region with the greatest availability of insects.

The researchers identified another factor determining the development of the common swift’s chain migration: they cannot claim a territory in the same way as birds that spend more time on the ground.

“The core reason why the common swift engages in chain migration, whereas almost all other birds such as songbirds, ducks, geese and waders have leap-frog migration patterns, can probably be found in the amount of time they spend airborne. The common swift is unique in spending ten months in the air,” says Susanne Åkesson.

“I think it is amazing that they know where food is to be found and when they should head for that specific location. They migrate over continents in such a way as to ensure continuous access to food and thereby to survive — they have a lifespan of over 20 years,” she continues.

The researchers tracked 102 common swifts (Apus apus) from eleven different populations that nest in Europe, from Swedish Lapland in the north to Spain in the south. Using micro data-loggers attached to the birds, which record data including time of sunrise and daylight duration, they were able to calculate longitude and latitude and thus to determine the location of the 102 individuals at various times during the year. The study involved researchers from 14 universities and bird conservation organisations.

Chain migration has previously only been observed in two species: the sharp-shinned hawk and the northern gannet.

COVID-19 plus flu disaster in the USA?

This 19 September 2020 video says about itself:

COVID-19 crisis escalates across Europe

France has seen a record number of new coronavirus cases, with more than 13,000 infections registered in the past 24 hours. The health ministry says 154 people died in hospital on Thursday, the highest number in four months.

The United Kingdom government is considering whether to impose a second national lockdown, after daily cases in England nearly doubled – to around 6,000 – in the past week. More restrictions have also been announced for the North West and Midlands areas.

Many other European countries are introducing new measures to curb the spread of the virus.

Movement is being limited in Spain’s capital, Denmark is applying a curfew for bars and Iceland will close pubs in the capital for four days.

Meanwhile, Israel has returned to a nationwide lockdown for a second time, following a spike in numbers.

This has come at the height of the Jewish holiday season.
Globally, the number of COVID-19 cases has now passed 30.5 million.

What will happen when COVID-19 and the flu collide this fall?

The upcoming face-off in the U.S. could lead to one virus dominating or a deadly combo

September 18, 2020 at 4:43 pm

The specter of a “twindemic” — two epidemics at the same time — looms as cold and flu season is set to start in October in the Northern Hemisphere. No one can predict what will happen when flu meets COVID-19, but public health officials are urging people to prepare for the worst.

In this case, the worst would be a bad year for influenza, which in the United States has killed 12,000 to 61,000 people annually and hospitalized between 140,000 and 810,000 each year since 2010, combined with a resurgence of coronavirus infections. Together, the two could stress health care and public health systems beyond their limits.

“We could see a perfect storm of accelerated COVID-19 activity as people gather more inside in particular, as they become increasingly fatigued with the mask wearing, social distancing and the hand hygiene, and as they are exposed to seasonal influenza,” said Jeanne Marrazzo, director of the infectious diseases division of the University of Alabama at Birmingham, during a news briefing from the Infectious Diseases Society of America, or IDSA, on September 10.

Some states are getting coronavirus spread under control, but hospitalization levels haven’t gone down much, she said. “Overall, we still are on … a razor’s edge when it comes to COVID,” and influenza remains unpredictable. “We really can’t be complacent about this.”

Infectious diseases experts worry about a conjunction of influenza and coronavirus for multiple reasons, beyond overburdened health systems. Teasing out whether a person has flu or coronavirus — which have very similar symptoms — will require testing for both viruses, at a time when turnaround for COVID-19 tests is often slow. And some people may get infected with multiple viruses simultaneously, which could make symptoms more severe.

But hints from the Southern Hemisphere give hope that the worst may not happen. Scientists usually forecast flu seasons’ severity in the north by watching what happens south of the equator, where flu season falls in the middle of the year. This year, the preview held good news: a mild season for flu and some other respiratory viruses.

Southern exposure

Countries in the Southern Hemisphere normally start seeing flu cases in May, and the flu season typically peaks in July and peters out around October. For the past five to six years, flu seasons in Australia have been bad. For instance, in 2019, Australia got an early flu season that started in March and “went on for a very long time,” says Kanta Subbarao, a virologist who directs the World Health Organization’s Collaborating Centre for Reference and Research on Influenza at the Doherty Institute in Melbourne, Australia.

It wasn’t looking good for 2020 either. This year, flu season started even earlier, she says. “We started seeing some flu activity in January and February,” summer in the Southern Hemisphere. “Then it just completely stopped. It just fell off a cliff at the end of March, essentially when COVID-19 started appearing.”

From April through July, only 33 people had positive flu results in Australia out of 60,031 people tested, an international group of influenza researchers report September 18 in Morbidity and Mortality Weekly Report published by the U.S. Centers for Disease Control and Prevention. The flu was also nearly nonexistent in South Africa and Chile in the late spring and early summer months. Together, the three countries recorded just 51 flu cases among 83,307 people tested, for a positivity rate of 0.06 percent. By contrast, over the April through July periods in 2017, 2018 and 2019, a total of 24,512 out of 178,690 people had positive flu tests, a positivity rate of 13.7 percent.

Travel restrictions that closed Australia’s borders may have prevented influenza from being imported from elsewhere. Lockdowns, school closures, mask wearing, social distancing and hand washing — all measures taken to prevent the spread of COVID-19 — may have also quashed any influenza outbreaks that remained. Other Southern Hemisphere countries have also reported unexpectedly low levels of influenza and another common respiratory virus called respiratory syncytial virus, or RSV, she says.

Public health officials anticipated a resurgence of influenza and RSV once Australia reopened schools, but that hasn’t happened, Subbarao says. “We have looked very long and hard,” but have found very little of either disease, Subbarao says. Instead, “what we’re finding is rhinovirus,” which cause colds, Subbarao says, suggesting that rhinovirus hasn’t been phased by all the public health measures.

Northern predictions

Flu season may also be lighter than usual in the Northern Hemisphere as a result of reduced travel, former CDC director Tom Frieden said in an IDSA news briefing on September 15. Flu “gets around the world when people travel, and there’s not much traveling going on.” But COVID-19 remains a threat, he warned “If you doubted that COVID was more infectious than flu, look at South Africa or Chile, where COVID is spreading like wildfire and flu isn’t spreading at all.”

In the United States during the 2019–2020 flu season, flu cases also took a nosedive after public health measures were put in place to limit coronavirus spread. Flu cases started increasing in November 2019, and between December 15 and March 7, more than 20 percent of flu tests were coming back positive each week, according to the MMWR report. By the week of March 22, plenty of people were still getting flu tests, but only 2.3 percent of the results came back positive. Many of those influenza-like illnesses that weren’t due to flu may have been COVID-19 (SN: 6/25/20).

Since the week of April 5, fewer than 1 percent of flu tests have detected the virus, and off-season flu counts are at historical lows. From May 17 to August 8, only 0.2 percent of flu tests gave positive results, compared with 2.35 percent last year, 1.04 percent in 2018 and 2.36 percent in 2017. The sharp drop-off of flu cases might just have been the natural end of the flu season. However, the decrease in percent positivity after March 1 “was dramatic, suggesting other factors were at play,” the researchers wrote.

If social distancing and other measures to contain COVID-19 remain in place, the flu season in the United States might be blunted or delayed, the researchers wrote. But don’t bank on it, other experts say. If there’s anything experts who try to predict influenza activity have learned is that flu is unpredictable.

Battle for dominance

Predicting how flu will play with COVID-19 is trickier still.

Richard Webby, a virologist at St. Jude Children’s Research Hospital in Memphis, Tenn., is involved in efforts to predict which flu strains will dominate so that vaccines can be designed accordingly. One pattern Webby and other flu researchers have seen over and over again is that when a new pandemic influenza strain arises, it pushes out another strain. For instance, when the 2009 H1N1 influenza pandemic strain emerged, another H1N1 flu strain that had been circulating since 1977 disappeared.

SARS-CoV-2 — the virus that causes COVID-19 — and influenza will be competing for hosts to infect, which may result in one virus squeezing out the other, Webby says.

“I find it difficult to believe that there’s going to be widespread flu and widespread COVID activity at the same time. I think one of them will dominate. I couldn’t tell you which one it will be,” he says. Admittedly on the fence, he says that if asked to bet which disease will predominate, “I’d put a little bit of money each way.” He says the two diseases probably won’t both go gangbusters, “but I could easily be horribly wrong.”

Getting a double dose

In the battle for hosts, sometimes both viruses win, infecting a person at the same time.

As New York and New Jersey became hot spots of coronavirus spread in the spring, COVID-19 “patients were coming around the clock” to St. Joseph’s University Medical Center in Paterson, N.J., where Balraj Singh works. Singh, a hematologist and oncologist, was called in to treat the patients’ blood clots and plummeting blood cell counts. As he did so, he decided to also test his patients for infections with other viruses that produce similar symptoms. He and colleagues discovered that three of their patients were infected with SARS-CoV-2 and influenza at the same time. They reported the cases August 18 in Cureus.

Two of the patients had to be intubated, but Singh and colleagues can’t say whether the dual infections made their illnesses worse. All were eventually discharged. It was important to publish the case reports “so somebody else can have a little bit of a head start” in recognizing that some people may have double trouble from viruses, he says.

flue shot sign

Coinfections with SARS-CoV-2 and influenza will probably be uncommon, says David Morens, a virologist and infectious diseases doctor who is the senior scientific advisor to the director of the U.S. National Institute of Allergy and Infectious Diseases in Bethesda, Md.

One analysis suggests only about 3 percent of COVID-19 patients were simultaneously infected with another virus, researchers reported online May 27 in the Journal of Infection. Those researchers examined 30 studies, mostly from China, that reported on dual infections with bacteria or viruses in people sick with COVID-19. The most common viruses to double up with SARS-CoV-2 were RSV and influenza A.

Broad defenses

It’s not impossible to catch viral infections at the same time or in quick succession, but getting one viral infection generally makes it harder to get another one, Morens says. That’s because viral infections tend to rev up the immune system’s generalized antiviral defense system, known as the innate immune system. Catching one virus sets off alarm bells in the form of virus-fighting immune chemicals known as interferons (SN: 8/6/20). For a short period after an infection, maybe weeks to months, the immune system stays on high alert with defenses at least partially raised to ward off any subsequent intruders.

That battening of the hatches against other viral invaders is different from the specific kind of immunity that comes from making antibodies against a particular virus. But it still might be useful. For instance, immunologist Ellen Foxman has long suspected that catching colds caused by rhinovirus may have delayed the 2009 H1N1 influenza pandemic in Europe.

“For years I’ve been looking for a way to test” that idea, says Foxman, of Yale School of Medicine. She and colleagues confirmed that flu and rhinovirus don’t seem to mix by examining data from three later flu seasons, spanning November 2016 to March 2019. They found that people were less likely than expected to have dual infections with rhinovirus and influenza, the team reported September 4 in Lancet Microbe.

Infecting human lung cells growing in laboratory dishes provided some clues to why. First, the researchers infected the cells with rhinovirus. Then they tried a few days later to infect the same cells with flu virus. Rhinovirus infections turned up activity of genes involved in the interferon response, preventing flu viruses from replicating in rhinovirus-infected cells, the researchers found. Blocking interferon allowed the flu viruses to reproduce in cells already infected with the cold virus. But interferon response doesn’t last long, “maybe a week or two,” Foxman says.

And that type of protection isn’t perfect, Subbarao says. About 10 percent of the respiratory illnesses are coinfections with two or more viruses.

Some scientists theorize that vaccines against tuberculosis, measles or polio — which contain live, weakened virus or bacteria — might give some measure of protection against COVID-19 by generally toughening the immune system, Subbarao says. FluMist, a nasal spray flu vaccine mainly used for children, might also provide a little nonspecific armor against other viruses, though she cautions that the protection is short-lived and intended only as a stop-gap until there’s a safe, reliable and widely available coronavirus vaccine.

Injected flu vaccines are usually made with killed viruses and don’t offer the same generalized virus protection as live vaccines. But public health officials are urging people to get flu vaccines, to reduce the chances of getting infected with both viruses and hopefully ward off a nasty flu season.

“If there’s ever a year you need to get your flu shot, get your kids vaccinated, this is the year,” Marrazzo said.

Hammerhead sharks, new research

This 2016 video from Mexico is called Face to face with huge smooth hammerhead in Cabo San Lucas.

From Nova Southeastern University in the USA:

New shark research targets a nearly endangered species

September 15, 2020

They are some of the most iconic and unique-looking creatures in our oceans. While some may think they look a bit “odd”, one thing researchers agree on is that little is known about hammerhead sharks. Many of the 10 hammerhead shark species are severely overfished worldwide for their fins and in need of urgent protection to prevent their extinction.

To learn more about a declining hammerhead species that is data-poor but in need of conservation efforts, a team of researchers from Nova Southeastern University’s (NSU) Save Our Seas Foundation Shark Research Center (SOSF SRC) and Guy Harvey Research Institute (GHRI), Fisher Finder Adventures, the University of Rhode Island and University of Oxford (UK), embarked on a study to determine the migration patterns of smooth hammerhead sharks (Sphyrna zygaena) in the western Atlantic Ocean. This shark, which can grow up to 14-feet (400 cm), remains one of the least understood of the large hammerhead species because of the difficulty in reliably finding smooth hammerheads to allow scientific study.

To learn about smooth hammerhead behavior, the research team satellite-tagged juvenile hammerhead sharks off the US Mid-Atlantic coast and then tracked the sharks for up to 15 months. The sharks were fitted with fin-mounted satellite tags that reported the sharks’ movements in near real-time via a satellite link to the researchers.

“Getting long-term tracks was instrumental in identifying not only clear seasonal travel patterns, but importantly, also the times and areas where the sharks were resident in between their migrations,” said Ryan Logan, Ph.D. student at NSU’s GHRI and SOSF SRC, and first author of the newly published research. “This study provides the first high resolution, long term view of the movement behaviors and habitats used by smooth hammerhead sharks — key information for targeting specific areas and times for management action to help build back this depleted species.”

The researchers found that the sharks acted like snowbirds, migrating between two seasonally resident areas — in coastal waters off New York in the Summer and off North Carolina in the Winter. Their residency times in these two locations coincided with two environmental factors: warmer surface water temperatures and areas with high productivity — indicative of food-rich areas.

“The high-resolution movements data showed these focused wintering and summering habitats off North Carolina and New York, respectively, to be prime ocean “real estate” for these sharks and therefore important areas to protect for the survival of these near endangered animals,” said Mahmood Shivji, Ph.D., director of NSU’s GHRI and SOSF SRC, who oversaw the study.

Identifying such areas of high residency provides targets for designation as “Essential Fish Habitat” — an official title established by the US Government, which if formally adopted can subsequently be subject to special limitations on fishing or development to protect such declining species.

The tracking data also revealed a second target for conservation. The hammerheads spent a lot of resident time in the winter in a management zone known as the Mid-Atlantic Shark Area (MASA) — a zone already federally closed for seven-months per year (January 1 to July 31) to commercial bottom longline fishing to protect another endangered species, the dusky shark. However, the tracking data showed that the smooth hammerheads arrived in the MASA earlier in December, while this zone is still open to fishing.

“Extending the closure of the MASA zone by just one month, starting on December 1 each year, could reduce the fishing mortality of juvenile smooth hammerheads even more,” said Shivji. “It’s particularly gratifying to see such basic research not only improving our understanding of animal behavior in nature but also illuminating pathways for recovery of species and populations that have been overexploited so we can try and get back to a balanced ocean ecosystem.”
