New Zealand has one of the world's largest ocean territories, but the marine environment is at risk from climate change, pollution and fishing.
The unpopular badger cull has had only 'modest' success in reducing bovine TB, according to a recent report. What would an alternative approach that was effective and humane look like?
Taxonomists are becoming as rare as some of the species they work on, and this puts museum collections and conservation efforts under threat and increases the risk of biosecurity incursions.
It's possible the white spot virus is now endemic in Australia - in other countries where it has broken out, it has never been eradicated.
An invasive insect native to Asia, Halyomorpha halys, has been detected in the US, Canada and southern Europe. It’s now made its debut in Paris.

Exotic pets may rank highly on the novelty and excitement scale, but little is known about their ownership in Australia.
President Trump wants to slash global health funding at a time when more investment is needed, not less. This spending can protect Americans – as well as foreigners – from deadly diseases.
A scientific breakthrough in a vacuum may be free of ethical implications. But many developments can be used for good or evil, or both. There's a fine balance on what to control and to what extent.
Keeping non-native reptiles as pets is against the law – with good reason. Alien species traded on the black market can potentially establish themselves in the wild if they are released or escape.
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.
In the science world, laboratories are essential but safety precautions should be taken to prevent any incidents like the Ebola outbreak or biochemical attacks.
The federal government's recent White Paper on developing northern Australia has disturbing echoes of the 1890s, a time when unbridled capitalism and indentured labour developed the North.
