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

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 [...]

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) [...]

WETLANDS: LIFE SUPPORT FOR THE GREAT BARRIER REEF

WETLANDS: LIFE SUPPORT FOR THE GREAT BARRIER REEF

By Dr Fernanda Adame and Emeritus Professor Angela Arthington The Great Barrier Reef (GBR) is well recognised as one of the most biodiverse and valuable ecosystems on Earth. However, few of us appreciate that one million hectares of wetlands are the life support system for this important ecosystem. In this article, Dr Fernanda Adame and Emeritus Professor [...]

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 [...]

Turtley sick moves: rescuing weak sea turtles and the science aimed at helping their equally weak populations

Turtley sick moves: rescuing weak sea turtles and the science aimed at helping their equally weak populations

  Author: Dr Ryan Pearson Sea turtles are threatened. Literal boatloads of things affect their already low survival rates, most attributable to humans. Plastics, fishing entanglements, temperature increases, habitat degradation and actual boat strikes are killing turtles and affecting their populations in many other ways. Ultimately threatening their very existence. Knowing this, when my buddy [...]
