The Endangered Species Act was enacted in 1973 partly to help save the bald eagle, the U.S. national symbol, from extinction. Should public appeal influence which species get priority?
How should the US spend limited funds for conserving endangered species? A new data tool lets managers compare different strategies so they can allocate money to protect the most species.
Releasing a female wolf on Isle Royale, Oct. 2, 2018.
The National Park Service is moving wolves to Isle Royale in Lake Superior to replenish a small pack on the island. Wolves prey on moose, which are overgrazing the island. It doesn't hurt that they are charismatic.
Fossa (Cryptoprocta ferox) at the Houston Zoo.
The fossa, Madagascar's largest predator, is a cat-like carnivore that eats everything from insects to lemurs. Because they are rare and elusive, scientists know very little about them, including how many there are.
Scientists asked young people to draw what they would like the natural world to look like when they're older. Their imagination could help make conservationists more ambitious.
The majestic White Ibis.
The ibis has become an Australian cultural phenomenon. The birds' tenacity and fearlessness as environmental refugees mean they attract love and hate alike.

The Trump administration wants to step up logging, saying it will benefit wildlife by reducing forest fire risks. But wildfires create habitat for threatened Spotted Owls and many other species.

As California reels from another devastating fire season, environmental resource scholars explain how the state – and other fire-prone areas – can better prepare and coexist with wildfires.
Conservation groups are organizing soccer games to help bridge the gaps between park rangers and communities.
Environmental organizations are using games to engage communities on conservation matters.
African elephant bull.
Cells that transmit nerve impulses in the part of elephants' brains responsible for functions such as learning and memory are structured differently from those of any other mammal.
An elephant successfully translocated by SAN Parks from Kruger National Park to Addo Elephant National Park.
Translocations have become more frequent in Africa. Elephants are the biggest animals to be moved.
A research study found that most of the debris in gulls’ stomachs is plastic – exposing the birds to high levels of chemical contaminants and potentially limiting their reproductive success.
Seagulls have no qualms about sifting through dumps for scraps. But this buffet comes at a cost, filling their stomachs with plastic, glass, metal and even building materials.

Social media data can reveal where people are watching nature – and consequently where animals may be under pressure.
Dingoes are usually solitary, but can forage in groups near human settlements where food is abundant.
An attack on a WA mine worker has highlighted the danger of wild dingoes, particularly when attracted by humans' food - one of the factors that can make an attack by wild predators much more likely.
The endangered Sierra Nevada bighorn sheep.
As attempts to water down the Endangered Species Act have accelerated, public support for the act has stayed high. Then why do politicians keep trying to weaken the act?
Elephants at the Okavango Delta, Botswana.
Botswana is launching a consultative process to review the current ban on elephant hunting.
As ponds dry up, so too does our connection to nature.
The Canada 150 Sequencing Initiative will sequence the genomes of 150 organisms important to Canadians, publishing the results in public databases.
By sequencing the genomes of other species, we can better understand our place in natural history.

It's becoming harder and harder for animals to find human-free spaces on the planet. New research suggests that to try to avoid people, mammals are shifting activity from the day to the nighttime.
Snowshoe hares near the now closed Giant Mine outside of Yellowknife, N.W.T show signs of arsenic contamination.
Historical gold mining at the Giant Mine near Yellowknife, N.W.T. released toxic arsenic into the environment. Snowshoe hares are showing signs of poisoning.
For decades, state and federal governments have shed environmental budgets and staff. Now it's up to volunteers to fill the gap.
