African elephant in Kruger national park, South Africa.
In large ecosystems, managing elephant populations so they don't exceed a certain threshold number is arbitrary.
Mimicking the future.
A real-life experiment to mimic future conditions for soils affected by climate change suggests that some of the biggest impacts could be to ecosystems buried out of sight beneath our feet.
Giraffes prefer the open space and scattered trees of the African savanna.
Ecological literacy is needed to guide global tree planting initiatives to avoid damaging some ecosystems.

Federal environment minister Sussan Ley said the environment doesn't necessarily need all its water, whereas farmers do. But denying rivers even part of their water can harm their health in many ways.
Adani Australia CEO Lucas Dow has now collected all the necessary approvals.

It's been years in the making, but Adani's controversial Queensland coal mine is finally shovel-ready. Yet significant scientific questions remain, such as the impact on the region's aquifers.
A grassland earless dragon at Jerrabomberra, NSW, November 1991. The search is now on for this species’ Victorian cousin.
The Victorian grassland earless dragon may well be the first lizard species driven to extinction on Australia's mainland. But conservationists aren't ready to declare it dead just yet.
An aerial photo of Borneo shows deforestation and patches of remaining forest.
A new study lays out a road map for protecting and restoring 50% of Earth's surface, targeted to preserve biodiversity and maximize natural removal of carbon from the atmosphere.
Marine parks are good for fish - especially if they’re in the right areas.
With strategic planning, the marine protected area network could be a third smaller, cost half as much, and still meet the international target of protecting 10% of every ecosystem.
Feral horses have severely damaged the landscape in Kosciuszko National Park.
Feral horses are a clear point of division between parties in this weekend's election. Labor has pledged to repeal the Coalition government's bill to preserve large numbers of brumbies.
Eastern quolls have been introduced in Booderee Nation Park as part of a rewilding project.
Rewilding is gaining popularity around the world, as a means to restore ecosystems to their ancient state. But just like Vegemite, Australian rewilding projects need to have a unique flavour.
The West Moberly First Nation would like to see biodiversity-rich riparian areas in the Peace River Valley, in northeastern British Columbia protected. They will be destroyed by the Site C hydro dam, currently under construction.
Countries can protect biodiversity and recognize Indigenous peoples as conservation partners.
Dozens of brumbies were found dead near Santa Teresa in Australia’s remote interior.
Mass wildlife die-offs, such as those wrought by Australia's recent heatwaves, make for grim headlines. But the wider effects of extreme weather are more complex, and can be remarkably long-lasting.
There are 130 billion gallons of water in Wisconsin’s Lake Mendota, and now, trillions of spiny water fleas.
It's cheaper to prevent biological invasions than to react after they happen. But it's hard to detect invaders while there are still just a few of them. Knowing when and where to look can help.
Turning street lights off at midnight could save money, energy and help nocturnal ecosystems thrive.

Some media have reported shark numbers at 'plague proportions' in Australian waters. But a new analysis suggests the opposite: species such as hammerheads and white sharks have plummeted in number.
The Gila monster.
The Gila monster gave humans a treatment for diabetes. What other medical miracles are we losing by failing to protect wildlife and ecosystems?
In the firing line.
We need to learn to coexist with wildfires the way many ecosystems do. We won't protect lives in the long term by trying to stamp the fires out.
The burrowing owl was once a common sight on the prairies. Now Saskatchewan and Alberta have fewer than 1,000 breeding pairs.
Carving up ecosystems or opening them to development puts the survival of species at risk.
Opportunities to help drive the energy transition are everywhere - even in Western Australia’s remote salt pans.
Peter C. Doherty
Nobel Prizewinning health researcher Peter Doherty reflects on the challenge of delivering a healthy climate for the world. From hydrogen power to wooden skyscrapers, the options are endless, but all require leadership.
The dingo, Australia’s largest mammalian carnivore, has a broad diet that varies across the continent.
A survey of 32,000 samples of dingo droppings and stomach contents reveal that this predator's appetite is as wide-ranging as Australia's landscapes. But medium and large mammals are top of the menu.
