When ecosystems aren't able to repair themselves, it's up to us to intervene.
To understand the effects of a big die-off, researchers set up experiments with wild boar carcasses.

Death is a natural part of ecosystems. But it's unusual for a large number of animals to all die at once. Researchers are investigating how a mass mortality event affects what's left afterwards.
The Amazon will take a lifetime to recover from this year's fires – if it ever does.

Tackling the extinction crisis is not just about protecting each species. It's also about preserving their home.

The False Bay ocean food chain in Cape Town began to change significantly in 2015 with the appearance of shark-eating killer whales.
Mangroves growing strong.
Mangrove forests grow in the tidal lagoons of tropical coastlines and they could actually benefit from climate change. Here's what that means for us.
2016’s warm winter meant not enough snow for the start of the Iditarod sled dog race in Anchorage, so it was brought by train from 360 miles north.
For everyone from traditional hunters to the military, the National Park Service to the oil industry, climate change is the new reality in Alaska. Government, residents and businesses are all trying to adapt.
Only you can prevent hothouse earths.
What can we expect from our future climate after looking at the 'Hothouse Earths' of the past?
Not interested in your new favorite band.
An AC/DC-loving biologist tests the band's 1980 assertion that "rock 'n' roll ain't noise pollution." Turns out it can be – and the negative effects of noise can ripple through an ecosystem.
An ancient giant.
Despite them living for up to 2,500 years, researchers have discovered several baobab trees in Africa have died. Aida Cuni Sanchez on why these trees have a special place in our world.

Biologists are finding new evidence that these ocean invertebrate grazers don't just ingest whatever they catch. They can actually be picky eaters – and their choices might influence ocean food webs.
Pacific seabirds, such as this Great Blue Heron, can accumulate mercury in their bodies from the fish they eat.
Mercury levels in seabirds living off the coast of British Columbia have been stable in recent years. New research suggests that this may be due to changes in their diet, not pollution control.
Scientists are pioneering a new way of monitoring water species, using techniques more familiar to fans of crime scene TV shows.
A tree house used to observe the Tungurahua volcano in Ecuador which has made a point of developing ecotourism to boost economic growth.
The world must embrace an economy where people and the planet are what matters the most.
Fragments of woodland surrounded by cleared land in south west Australia.
Australia may have reputation for vast areas of wilderness, but in reality the continent's ecosystems have been chopped and diced. Now we need to protect what's left.
Viruses are not all bad. In fact, many ecosystems would not function without them.
The word "virus" strikes terror into the hearts of most people. But most viruses are actually vital to our very existence.
‘I don’t do public transport.’
Bat populations have been hammered by deforestation. Efforts like tree-planting schemes are a step forward, but they're doomed to fail unless we apply a bit more local knowledge.
Thylacines are extinct - and perhaps we just have to accept it.
Many ecosystems have changed so radically that it is no longer possible to restore them to what they once were and in other situations it is not appropriate.
