Rivers, lakes, and wetlands support extraordinary diversity. Such bodies of water host more species per square kilometre than forests or oceans. Yet they are losing this biodiversity two to three times faster than forests and oceans. Populations of freshwater animals, including river dolphins, sturgeon, beavers, crocodiles, and giant turtles, have already plummeted by 88%.

New tools (i.e. deep learning / computer vision) are allowing data to be processed at vast rates which is making data more accessible and useful. However, converting raw data into meaningful insights for ecological research can be challenging. Data nodes. Photo: Akamai. Through the years, ecologists have become familiar [...]
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 [...]

The 2019 Great Barrier Reef Outlook Report from the Australian Government Great Barrier Reef Marine Park Authority identifies the risk of nutrient runoff from catchments for the reef as Very High, the same rating as the 2014 and 2009 reports. --- This [...]
By Dr Chris Brown Reading Time: 557 words about 3 minutes. We usually think of nutrients moving down rivers to the ocean, not the other way around. But in many temperate rivers of the northern hemisphere migration of salmon brings nutrients from the ocean to rivers and surrounding vegetation. Male Pink Salmon, identifiable because of [...]

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 [...]
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 [...]
