Fragmentation threatens mangrove forests but protection can help – in some areas

Fragmentation threatens mangrove forests but protection can help – in some areas

By Dr Mischa Turschwell Read Time: 342 words about 2 minutes. Mangrove forest conservation is increasingly attracting international interest. That’s because mangroves support incredible biodiversity, enhance fisheries, protect vulnerable coastal communities from storms, and reduce climate change by storing carbon.  Lone Mangrove Sunset. Photo: Unknown. Unfortunately, mangrove forests remain one of the worlds most threatened ecosystems. Pressures from forest fragmentation, climate change, increasing exploitation [...]

Can trees control algal blooms – you’d be surprised

Can trees control algal blooms – you’d be surprised

By Professor Michele Burford Reading Time: 537 words, about 3 minutes. Algal blooms are a major issue for water security globally and in Australia. We have seen the damage algal blooms have had on Murray-Darling Basin and the issues Florida have had with the recent 'red tide' epidemic. As our climate changes, we can expect [...]

Climate change threat to fish diversity in Murray-Darling Basin

Climate change threat to fish diversity in Murray-Darling Basin

By Mark Kennard Read Time: Words 518 about 3 mins Native freshwater fish diversity in the Murray-Darling Basin could be under serious threat from climate change in coming decades. This potential loss of biodiversity could result in a further decline in the health of the Basin. Murray Darling Basin. Photo: iStock Freshwater fishes are highly [...]

The ecological importance of groundwater along the Fitzroy River

The ecological importance of groundwater along the Fitzroy River

By Ryan Burrows Article Read Time: 623 words about 4 minutes. Groundwater upwelling to rivers not only sustains surface flow but also delivers nutrients and creates favourable conditions for algae growth, importantly algae is a critical food source for aquatic animals. The Fitzroy River is located in the West Kimberley region of Western Australia. Geikie [...]

While Australia burns under a changing climate, our mangroves die-off

While Australia burns under a changing climate, our mangroves die-off

By PhD student Yota Harada Climate driven mass die-back is causing significant changes in mangrove ecosystems. Numerous marine species, including crabs, prawns and fish, rely on mangroves for nurseries, refuges and food. Mangrove forests support global fisheries and the livelihood's of people, but large-scale mortality of mangroves is anticipated due to climate change and associated [...]

Climate change and poor water quality are placing unprecedented pressures on the reef, and it is imperative that these stressors are eased to provide the reef with an opportunity to recover.   [...]

The Great Isoscape: Using barnacles to retrace oceanic movements

The Great Isoscape: Using barnacles to retrace oceanic movements

By Dr Ryan Pearson Techniques for tracking marine animals and objects have long been evolving; gaining in accuracy and reliability. However, most techniques rely on accessing an animal prior to tracking and few techniques are capable of retracing historical movements. Along with conservation efforts for threatened species, marine tragedies (where vehicles disappear in the ocean) [...]

Should we keep hanging our water out to dry – or is there another solution?

Should we keep hanging our water out to dry – or is there another solution?

  By Professor Fran Sheldon As the drought tightens its grip on southeastern Australia many towns look like running out of drinking water with a forecast of millions of dollars needing to be spent to keep regional communities viable until the drought breaks. This current drought is occurring hot (pardon the pun) on the heels [...]

EFFECTIVE ACTION NEEDS ACCESSIBLE SCIENCE

EFFECTIVE ACTION NEEDS ACCESSIBLE SCIENCE

  By Dr Chris Brown Coastal wetlands are globally threatened. However, the plight of these habitats, like mangrove forests, seagrass meadows and saltmarshes, is not well recognised relative to other coastal ecosystems, such as coral reefs. This translates into funding shortfalls both for the science needed to address coastal wetland decline and for the protection and [...]

Prey availability and flow conditions drive changes in barramundi abundance

Prey availability and flow conditions drive changes in barramundi abundance

By Mischa Turschwell Predator-prey interactions between fishes are important ecological processes that help maintain healthy populations and ecosystems. But often we don’t know if predators control prey numbers (top-down control) or if the number of prey available controls predator numbers (bottom-up control). We also don’t know how these interactions might change if environmental conditions like [...]
