Coral reefs are in trouble, but other marine species are also feeling the strain but are off the conservation radar.
Many Caribbean reefs are now dominated by sponges.
Marine sponges are ancient organisms that have survived mass extinctions. Many are more tolerant of climate change and may dominate over corals in future reef systems.
The GBR Foundation fills a gap in funding research that might be seen as too much of a risk by other agencies.

Federal Labor has pledged to withdraw the A$443 million given to the Great Barrier Reef Foundation. But the foundation's decisions are led by science, and free of undue influence, its chief scientist says.
Successive governments have seen the Great Barrier Reef not just as a scientific wonder, but as a channel to further economic development.
The $444 million awarded to the Great Barrier Reef Foundation has been criticised as a politically calculated move. But governments have been asking what the reef can do for them ever since colonial times.
Marine parks protect fragile ecosystems, like coral reefs.
What would you do if you saw a fisher breaking the law? Would you report the offender to the police? Confront them? Or would you do nothing? These choices affect the future of marine protected areas.

Scientists have used 'tree rings' in coral to identify centuries of stress.
Can geoengineering buy the coral reefs more time?

Climate mitigation efforts are unlikely to be enough to save critical ecosystems like the Great Barrier Reef. We may need to consider more radical environmental engineering.
Some fish fared better than others amid the extreme temperatures of the 2016 heatwave.

The 2016 heatwave that caused mass bleaching on the Great Barrier Reef didn't just kill corals - it also significantly changed the makeup of fish communities that call these reefs home.

Not everything humans put in the ocean is garbage. From walls of tyres to sunken sculptures, reef restoration is both a science and an art.
Green sea turtle eating seagrass off Lizard Island.
New research highlights the role of sea turtles and dugong in the dispersal of seeds and maintenance of seagrass meadows, an important marine habitat and the primary food source for both animals.
The new funding is focused on measures that are already in the foreground.
The federal government's new $500 million funding package for the Great Barrier Reef seems predominantly focused on the tactics that are already being tried, without much success.
Staghorn and tabular corals suffered mass die-offs, robbing many individual reefs of their characteristic shapes.

The 2016 bleaching event resulted in 30% mortality on the Great Barrier Reef, with many corals dying of the heat before they bleached and the loss of branching corals creating less complex reef structure.
Boat noise can interfere with the underwater communication of fishes and other marine animals.
The noise from motor boats, sonar and other industrial activity interferes with the underwater chatter of fishes.

New global communities of concerned citizens can help protect iconic places such as the Great Barrier Reef. But the scope of these remote communities must extend beyond mere 'slacktivism'.
Bill Shorten spent a lot of his Tuesday press conference to support Jay Weatherill answering questions about Adani.
Adani is being seen as a test of Bill Shorten's commitment to policy integrity versus his willingness to say and do whatever is politically expedient.
Bill Shorten said he had become increasingly sceptical of Adani in recent months.
Bill Shorten has taken a further step toward opposing the proposed Queensland Adani coal mine.

Giant triton molluscs are a useful ally in battling the coral-grazing crown-of-thorns starfish.

The federal government's new funding aims to spread the net wide in investigating possible ways to protect the Great Barrier Reef's corals. Winning this battle will require a wide range of weapons.
Pause and reflect on what really makes wilderness valuable.

Imagine being one of the last few people alive. Would that make it ok to destroy the natural world? This thought experiment reveals the true value of nature, beyond the benefits to humans.
Endangered green turtles like this one on Raine Island in Queensland’s far north face an uncertain future – one that depends largely on effective conservation measures.
With 99% of green sea turtles in the northern Great Barrier Reef hatching as females due to changing climate, the future for this species now depends largely on effective global conservation measures.
