Climate Change strikes again: Warming rivers are reducing fish recruitment

There is an urgent need to understand what factors contribute to successful breeding and juvenile survival for Australia’s freshwater fishes, especially as many freshwater fish species are affected by events like those that led to the recent fish kills in the Murray-Darling Basin.

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 [...]

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.   [...]

In the face of degradation: Planning framework can help safeguard Amazon wetlands

In the face of degradation: Planning framework can help safeguard Amazon wetlands

By Dr Vanessa Reis In the face of dramatic degradation of the Amazon ecosystems, a new conservation planning framework can help safeguard the floodplain wetlands. Floodplain wetlands are unique ecosystems often highly influenced by seasonal variation in their connection to rivers. They contribute to the Amazons high biodiversity and are used by the local people [...]

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 [...]
