Overfishing can teach us valuable lessons about ecosystem resilience.
Large-scale natural experiments such as oil spills, tsunamis and climate change are things you wouldn't want to do on purpose. But that doesn't mean they're not scientifically useful experiments too.
We should celebrate these amazing insects, not splat them.
Alpine meadows are a pretty rare sight in Australia.
The alpine landscapes of Australia's southeast and Tasmania are home to hundreds of rare plants and animals. They're healthy for now, but need careful looking after.
They might be eating your home, but termites play a vital role in ecosystems.

Termite damage costs Australian homes at least a billion dollars each year – but they are absolutely vital for ecosystems.
Bleached coral can take on luminously beautiful pink and purple hues - but don’t be deceived, these corals are under stress.
The bleaching hitting the Great Barrier Reef not only harms corals. As these close-up photos show, it also deprives many other species of a home and livelihood.

Animals and plants may not be able to keep up with the speed of climate change. We could help them move.
Australian defence ranges, such as Shoalwater Bay, cover some 3 million hectares of the country.
Australia's defence forces manage huge swathes of land which are home to valuable ecosystems. The new defence white paper finally acknowledges the importance of looking after them.
Extreme weather could trigger ecosystem collapse, including mass tree deaths.

Extreme weather will affect people and animals, as well as whole ecosystems. Research using satellites shows that ecosystems worldwide are vulnerable to collapse.
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.
Silver Lake, Wasatch watershed, Utah.
With a future of droughts looming for the US West, Utah’s Wasatch watershed offers a good model that combines conservation with nature-based recreation.
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.
Rivers in many agriculturally significant areas of Australia could lose water as the landscape grows greener.

Rising carbon dioxide levels are making plants grow faster, sucking up more water and reducing river flows in many agriculturally important areas of Australia, according to new research.
Dam useful: what have beavers done for you lately?
Listing the value of bees, beavers and others on the pages of the world's financial press helps to show that ecosystems deliver benefits worth staggering amounts of money - yet we scarcely keep track of it.
The modern emphasis on sanitation has a role in our shrinking microbial populations.
Human activities have altered whole ecosystems with declines in species diversity, extinctions and the introduction of weeds and pests. But it's not just the outside world we're harming.
‘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.
