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 […]

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 […]

Decline in tiger shark population defies expectations

By Dr Chris Brown Our new research has revealed a 71% decline in tiger sharks across Queensland’s coastline. The decline has been particularly rapid in southern regions which is unusual. Tiger sharks are top predators that have few natural enemies, so the cause of the decline is likely overfishing. The decline is surprising, because tiger […]

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

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 […]

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 […]

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 […]
