The study's lead author argues that measures such as expanding protected areas and establishing national parks do not necessarily translate to real progress in conservation.
A new study reveals that Vietnamese poaching boats, known as 'blue boats', encroached into Australian waters between 2013 and 2017. The study shows how workshop interventions deterred illegal fishing by Vietnamese fishers in Australia.
A new study found that baby coral reef fishes have evolved to grow larger muscles and swim faster than their non-reef relatives, allowing them to outpace other fish in the ocean. This adaptation is thought to be related to their association with reefs, where they need to navigate open ocean currents to find a home.
Researchers found that local stakeholders consider fairness in distribution of money from marine protected areas according to who holds rights over the area, rather than equality or costs incurred. This challenges common assumptions in conservation literature and practice, emphasizing the importance of explicit identification of local ...
New research on coral reef growth rates reveals a window of opportunity to save the world's coral reefs, but time is running out. The study shows that unless carbon dioxide emissions are drastically reduced, the growth of coral reefs will be stunted due to climate change.

The study, conducted by the ARC Centre of Excellence for Coral Reef Studies, suggests that this could lead to a decline in their ability to survive in environments already challenging for them.
Researchers found that coral reef ecosystems can no longer retain deposits of calcium carbonate due to ocean warming and acidification, leading to accelerated erosion. By the end of the century, coastal protection will be lost, impacting infrastructure and communities.

A recent study on the Great Barrier Reef reveals that crown-of-thorns starfish can navigate back to their shelters at dawn after feeding on corals at night. The research found that only starfish with a well-stocked larder, meaning they have an ample supply of coral prey, were able to find their way home.
A recent study found that leaving more big fish in the sea reduces CO2 emissions by sequestering carbon. Large fish like tuna and sharks contain significant amounts of carbon, which is released into the atmosphere when they are caught.
The Great Barrier Reef has lost half its corals in the past three decades, with small, medium, and large coral populations declining by more than 50 percent. This decline is driven by climate change, which is causing record-breaking temperatures to trigger mass bleaching events.

A world-first study examining the Great Barrier Reef's management found that people are managed at broader scales than ecological variation, suggesting a general principle for permitting and management. This approach may be more effective in sustainably managing ecosystems, especially small protected areas.
Researchers found that households more socially connected to others taking action were more likely to do the same, suggesting a 'like-attracts-like' effect. Household connections with the marine environment also played an important role in determining responses to climate impacts.
A recent study found that noisy boats and ships can affect the prey response of young fishes, leading to decreased activity and reduced swimming distance. This can result in slower escape responses and increased mortality rates among juvenile reef fish.
Juvenile crown-of-thorns starfish that switch to coral diets early exhibit enhanced growth rates and larger size, leading to increased reproductive capacity. This variation in early development can have significant consequences for crown-of-thorns population dynamics and coral reef ecosystem health.
Researchers found that baby blacktip reef sharks can tolerate the extreme conditions of their nurseries, but these environments face an uncertain future due to climate change. The habitats' dramatic temperature and oxygen fluctuations can be a strain on the young sharks.
A study found that national governments resist World Heritage 'in Danger' listings despite the sites being equally or more threatened than those already on the list. Low visibility strategies and industrial lobbying are prevalent in blocking environmental governance.
A new study reveals that two key species of Australian aquarium corals are particularly susceptible to bleaching due to recurrent heatwaves. The study's findings emphasize the need for targeted in-situ monitoring to ensure the long-term sustainability of the coral industry.
A new study found that the diets of reef fish dictate how fast different species evolve, with big vegetarian fish driving biodiversity. The study's authors built an evolutionary tree of life for nearly all fishes associated with reefs, examining variation in rates of species formation and asking what drives it.
A recent study found that only five percent of tropical reefs globally can meet multiple goals, including providing enough fishing stocks and maintaining biodiversity. Marine reserves placed in areas with low human pressures had the best results for helping reefs get on the 'A-list', meeting all goals simultaneously.
The Great Barrier Reef has suffered its third coral bleaching event in just five years, with the most recent event being the worst. Severe bleaching has struck all three regions of the reef, causing widespread damage to coral habitats.

The research tracked changes in gene expression in five coral reef fishes before, during, and after a severe marine heatwave, revealing species-specific responses to the heightened temperatures.
Scientists discovered dozens of new coral species during a recent expedition along the Great Barrier Reef, revealing that much of existing classification is deeply flawed. The team's findings suggest that biodiversity may be up to three times higher than previously thought.
Researchers discovered that coralline algae can build tolerance to ocean acidification over time, providing a potential solution for coral reef survival. The findings suggest that these algae may be able to resist the impacts of climate change on coral reefs.
A recent volcanic eruption created a new island in the South Pacific, and coral reefs have shown incredible resilience and recovery. The study found that one section of the island supported diverse coral reefs largely unaffected by the eruption, which provided a source of larvae to repopulate reefs around the rest of the island.
The 'blue boat' fleet, consisting of small fishing vessels painted blue, is stripping Pacific coral reefs of seafood, endangering food security for Pacific Island nations. The boats are allegedly operated by Vietnamese fishermen with no contract or insurance, and are traveling thousands of kilometers to fish illegally in Pacific waters.
A study found that clownfish population persistence depends on high-quality habitats, not shared genes. The researchers identified individual fish and their DNA over five generations to assess reproductive success.

A study published in Nature Sustainability found that most conservation initiatives follow a slow-fast-slow model, where initial adoption is slow but grows quickly as more adopters connect with potential adopters. This understanding can help policymakers design and promote effective conservation programs.
Researchers found that a fraction of the fish caught nearby could significantly improve health in tropical coastal areas. The study suggests that existing marine fisheries can substantially reduce malnutrition, but access to these nutrients is often restricted to those who need them most.

Researchers suggest a bolder approach to safeguarding coral reefs by focusing on land as well as the ocean. Implementing strategies like renewable energy, aquaculture, and restoring vegetation can reduce global emissions and enhance people's livelihoods. Current approaches to coral reef conservation are failing, and addressing the root...
A study found that shark pups born in stressed environments, like those with climate change and overfishing, lose their initial physical advantages. This means they start foraging later and have lower body conditions, affecting their survival rates.
The study confirms the importance of fish larvae produced in no-take zones for the health of fish populations within nearby fishing zones. The accuracy of the model was tested with field data, validating its predictions and providing valuable insights for reef managers.
A study led by Dr Chancey MacDonald found that fussy fish can survive and even thrive in deeper waters due to their ability to adapt their diets. The Triangle Butterflyfish, a dietary specialist, fed more selectively on preferred corals, while the Eight-Band Butterflyfish, a generalist, became more flexible in their diet with depth.
