Invasive species and diseases pose a major threat to agriculture – particularly in the countries that can least afford it.

At least 100,000 insects are among the many Australian species still to be formally identified. That’s a problem for any biosecurity experts who need to be able to spot potentially invasive bugs.
A ‘Biblical swarm’ of ‘super-moths’ from continental Europe is heading to the UK.
Transport, climate change and environmental destruction mean all sorts of species are bumping into each other for the first time.
A warming Earth could see invading species arrive in Antarctica via the floating “taxi service” of the sea. That could be a threat to the southern continent’s delicate ecosystem.
Eating cows and sheep is unsustainable. Here are some better alternatives.
Rats have lived with us for thousands of years.
Many pet fish end up in ponds, fountains and waterways. But before ditching your goldfish in the park, stop and think about the viruses you could also be releasing.
Freshwater covers only 0.5% of the Earth’s surface but is home to 10% of the world’s lifeforms.
Over 100 species are dependent on Ash trees for survival – we need to act fast.
Chytrid fungus has already wiped out six species of Australian frogs since the disease arrived in the 1970s. Without urgent action, seven more are facing extinction.
Invasive species cause some $120 billion in damages across North America yearly – and that’s just direct costs. A study of one species in one Wisconsin lake indicates the real toll is much higher.
If you’re hearing a strange chatter in your home, you may have gecko housemates.
There are birds we love to hate, such as the Noisy Miner. But much of the annoying behaviour on show may be a result of human-induced changes to habitats.
South west Australia is home to an astonishing number of plants and some of the country’s weirdest wildlife. Now we need to protect it.
The 2011 Japan tsunami illustrates how more marine creatures are crossing the oceans than ever before - and not all of them are friendly travellers.
There are now six species roaming wild, and their numbers are increasing dramatically as their population expands and through human action. As they spread, they raise uncomfortable issues for conservation.
We know a lot about the potential negative effects of ocean acidification on marine creatures. But might some species actually benefit? The answer is yes, but this isn’t necessarily a good thing.
Some Australian birds are pushing out other species, and even damaging trees. The good news is we can help stop the spread of these birds, by putting native plants in our gardens.
A small invasive fish known as the topmouth gudgeon has already wreaked havoc on European species and its arrival to the US and South America is only a matter of time.
