Europe’s breeding bird populations have shifted on average 1 kilometer north every year for the past three decades, likely driven by the climate crisis, according to one of the world’s largest citizen science projects on biodiversity.
Researchers looking to conserve Canada’s most endangered mammal take advantage of the creature’s seven-month hibernation season to mine footage and field data for more insights that will help the animals survive, said Adam Taylor, executive director of the Vancouver Island Marmot Recovery Foundation.

NIWA hazards analyst Ryan Paulik, who led the assessment, says overall 430,000 people – or nine per cent of the population – live in the zones of which 170,000 are in red and orange zones.
Satellite images have revealed 11 previously unknown emperor penguin colonies in Antarctica, boosting the number of known colonies of the imperilled birds by 20 percent.Philip Trathan, also at BAS, said: “The new breeding sites are all in locations where recent model projections suggest emperor penguins will decline.
In the Delaware Bay especially, where spawning takes place every May and June, you can’t talk about horseshoe crab breeding – and it is a spectacle – without also talking about the migratory shorebirds, like red knots and ruddy turnstones that depend on the eggs laid by the millions every year.
This means that the herd immunity threshold will also be higher than 60 percent in some places and lower in others.“I think the range of R0 consistent with data for Covid-19 is larger than most people give credit to,” said Marc Lipsitch of Harvard University, who has been advising health officials in Massachusetts and abroad.
“It also means my patient population is at the bottom of the list for access to the technology that’s needed to effectively do telemedicine.”.“When you need telemedicine everywhere, you see a vulnerable population that doesn’t have the means to use it,” Harwell says.
And on the flip side, New Orleans, with a population density of 431 people per square kilometer, reports 1,718 cases per 10,000.Or here’s another way to look at it: According to data assembled by the Financial Times, New York City has experienced a 408 percent increase in deaths from all causes since the beginning of the pandemic.
Due to extra security measures put in place during the global outbreak of Covid-19, she will have to wait a further 14 days before she can travel from prison to a post-correctional treatment facility, just in case she has been exposed to coronavirus while incarcerated.
The reason why Italy is suffering so badly, write University of Oxford researchers in a new paper in the journal Demographic Science, may be twofold: The country has the second-oldest population on earth, and its young tend to mingle more often with the elderly, like their grandparents.
In the Las Cienegas National Conservation Area Hall and partners, including the Arizona Fish and Game Department, Bureau of Land Management, Cienega Watershed Partnership and the U.S. Fish and Wildlife Service, have built a robust Chiricahua leopard frog “metapopulation” — i.e., a group of populations separated by space.
The bunnies, and the digital files that described them, remained identical over many months.“This is a very initial foray into one of the more promising applications of DNA data storage: ubiquitous storage,” says Sriram Kosuri, a biochemist at UCLA who was not involved in the work.
Even so, I believe we’ll easily meet our challenges and take better care of the people who inhabit the world of the future, without experiencing sustained shortages of food or other important resources.

“If you go to the most contaminated areas, like some sites in the Red Forest, on a spring day you can barely hear a single bird singing,” says Anders Møller, an ecologist at the University of Paris-Sud who has been studying Chernobyl since 1991.
The 18-month scientific study has discovered: The dolphins can breed earlier, live longer and are capable of faster population growth than previously thought, which makes them more resilient to human threats Scientists can accurately predict where they live using satellite data on seawater turbidity (cloudiness) and the distribution of their main prey The importance of non-fishery threats had been underestimated, including the parasite causing toxoplasmosis, which is spread by cats.
Theoretically, this genetic diversity would make the bats more resilient to climate change, because a population that’s more adapted to arid conditions can interbreed with a population that’s less so, in essence “gifting” the cold-adapted population the genes necessary to survive a warmer world.
In an era of increasing natural hazards and climate change, art can also communicate the future risks we face. Last year, on the sidelines of FOSS4G and Understanding Risk Tanzania, a mural challenge brought together young Tanzanian artists to communicate visually about risk and resilience.
On Wednesday, Pew Research released a report that compares Twitter users to the rest of the US population. Pew surveyed a nationally representative sample of 2,791 adult Twitter users about everything from their income and education to their thoughts on issues like race and immigration.
But a massive effort to catalogue the sex ratios at birth, for the first time, for every country, shows that’s not such a smart strategy after all.“For so long people just took that number for granted,” says Fengqing Chao, a public health researcher at the Institute of Policy Studies in Singapore.
