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 [...]

There are cross-benefits to protecting coastal wetlands in the wake of COVID-19

There are cross-benefits to protecting coastal wetlands in the wake of COVID-19

Dr Ryan Pearson Read Time: 503 words about 3 minutes. The effects of COVID-19 on the world has been profound. We're now re-evaluating intergovernmental, trade and personal relationships, and rethinking our consumer needs. Environmental groups have been encouraging people to 'eat more fish' in response to this pandemic.  Consumer surveys during the pandemic have  also highlighted [...]

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 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) [...]

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 [...]

From sharks in seagrass to manatees in mangroves, we’ve found large marine species in some surprising places

From sharks in seagrass to manatees in mangroves, we’ve found large marine species in some surprising places

Michael Sievers, Griffith University; Rod Connolly, Griffith University, and Tom Rayner, Griffith University When we think of mangrove forests, seagrass meadows and saltmarshes, we don’t immediately think of shark habitats. But the first global review of links between large marine animals (megafauna) and coastal wetlands is challenging this view – and how we might respond [...]

Assessing Deltas in Canada: We all live downstream

Assessing Deltas in Canada: We all live downstream

By Tim Jardine NOTE: This is a guest article written by Dr Tim Jardine from the School of Environment and Sustainability and Toxicology Centre at the University of Saskatchewan. So I’ve heard it said. And there’s some truth to it. Unless you’re camped on the top of a mountain peak, you’re going to be downstream of [...]

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 [...]
