There are so many fish in the ocean that if you took them out, important habitats and food sources for many creatures would be lost.

One way to protect our ecosystems is to confer legal rights on them. This idea is at the heart of the ‘rights of nature’ movement – but Australia has few examples of this principle in action.
What happens underground doesn’t stay underground. If we overexploit groundwater and kill off its species, we put surface species – including us – at risk.
South of Cape Cod, fiddler crabs and marsh grass have long had a mutually beneficial relationship. It’s a different story in the North, where the harms can ricochet through ecosystems.
The felling of iconic trees is a highly emotive issue – but the damage needs to be repaired with care.
Students learned not just a practical outdoor skill, but how to explain what they were learning to curious observers.
To protect nearly a third of Australia by decade’s end will mean expanding our national parks, Indigenous Protected Areas and protection across private land.
From dark dragonflies becoming paler to plants flowering earlier, some species are slowly evolving with the climate. Evolutionary biologists explain why few will evolve fast enough.
Every living thing leaves traces in its environment. By sampling water or even air for this environmental DNA, we can know which species live where.
Slime gets a bad name in popular culture, but it’s food for invertebrates who become food for many other creatures.
Wildlife populations continue to decline in the UK, one of the world’s most nature-deprived countries.
Monitoring and protecting the Kasanka bat colony helps protect bats from the entire sub-continent, and thus supports ecosystem services in a wide area.
Invasive ants are a major threat to biodiversity, according to a study.
Many animal species can be detected using a simple, low tech method of collecting DNA from the environment.
According to a new UN report, invasive species do more than US$423 billion in damage worldwide every year. Four articles explore examples, from mollusks to poisonous fish.
Modern ecosystems are very different to how they were just a few centuries ago.
Native trees have been found at new heights in the Scottish Highlands, demonstrating how mountain woodland could recover from deforestation – benefiting humans, wildlife and climate issues.
We used to focus just on protection of vital ecosystems like the reef. But as climate change and other threats accelerate, we need to actively help nature get ready for the heat.
What happens when wild native bush rats meet cockroaches they’ve never seen before?
Freshwater megafish numbers have fallen by 94%, according to one study.
