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.

A Galapagos land iguana (Conolophus subcristatus) © Island Conservation Human introductions of pigs, goats, burros, black rats, Norway rats, house mice and house cats to the Galápagos Islands left the unique biodiversity of this World Heritage site in shambles.
“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.
India: How to help communities break the vicious "disaster-poverty" cycle Disasters caused by natural hazards push the near poor to below the poverty line and contribute to more persistent and severe poverty, creating poverty traps.
It’s the biggest monarch butterfly breeding site the U.S. Forest Service manages in the Intermountain West. What you plant in your garden and flowerbeds this growing season will help or hinder pollinators, including monarchs. Everyone can help.” A monarch caterpillar eats a leaf on a butterfly milkweed plant.
“We could use an infinite amount of data to train the deep learning engine, because we were using simulations.” The researchers generated tens of thousands of simulated evolutionary histories based on differing combinations of demographic details: the number of ancestral human populations, their sizes, when they diverged from one another, their rates of intermixing and so on.
“Once that decline begins, it will never end.” Penguin Random House But Empty Planet is not a book about statistics so much as it is about what’s driving the choices people are making during the fastest period of change in human history.
Helping with that transition is an especially important challenge for the World Bank because most of the population growth in the coming decades will be in developing countries. I like to think that Korea’s embrace of sustainability was in part facilitated by World Bank supported environmental education programs in the 1990s.
And that’s why it was a bit jarring to read about a leading wildlife conservationist and wilderness advocate feeding grizzly bears. These bears are largely found in the Great Gobi A Strictly Protected Area, a wilderness region five times larger than Yellowstone National Park.
“It’s disappointing to be honest,” says Norm Merz, South Selkirk Caribou Management Plan coordinator and Kootenai Tribe of Idaho wildlife biologist. More time than caribou have, but there is a plan for the South Selkirk herd.
She argues that if women were treated more equally professionally, they’d have fewer kids and the land they farm would be more efficient, all of which would help save the planet.“Women are the primary farmers of the world,” Wilkinson says.
For most of the first half of the 20th century, population geneticists largely attributed genetic differences between populations and species to adaptation through positive selection.Motoo Kimura proposed in 1968 that most mutations might be neutral in effect rather than beneficial or harmful, and that shifts in the frequency of these neutral mutations dominated evolutionary change at the genomic level.Annual ReviewsBut in 1968, the famed population geneticist Motoo Kimura resisted the adaptationist perspective with his neutral theory of molecular evolution.
Overall, the event underscored how governments and health authorities in many developing countries face the dilemma of how to feed their growing population while ensuring their food is nutritious and discussed relevant strategies to transform nutrition security challenges into opportunities. As rice prices increase, relative to nutrient-rich foods, people will diversify their diets away from rice.
