The world’s leading aquatic scientific societies with 80,000+ members urgently call for cuts to global greenhouse gas emissions

Dire consequences for freshwater and marine resources without significant and fast action. In an unprecedented statement released recently, the American Fisheries Society (AFS) joined forces with 110 aquatic scientific societies representing more than 80,000 scientists across the world to sound a climate change alarm.  The societies call for drastically curtailed global greenhouse gas emissions to […]

Marine food webs struggle as climate change increases sea temperatures

Scientists at the University of Adelaide have found growing evidence that marine ecosystems will not cope well with rising sea temperatures caused by climate change. “Healthy food webs are critical for ecosystems so that the world’s oceans can continue to provide an important source of food for humans,” says lead author Professor Ivan Nagelkerken, from the University […]

A broad diet helps tropical fish survive a range shift due to climate change

The global redistribution of marine and terrestrial species due to climate change is a major concern for conservation planners and resource managers. Now new research, using data from long term surveys of tropical fishes, indicates that traditional studies of this range shift phenomenon largely ignore the sequential nature of species movement. The study, published in […]

Cetacean spotting in Timor-Leste

Timor-Leste is getting a conservation boost with plans for a marine conservation program. In collaboration with the Centre for Applied Conservation Science at the University of Adelaide, Conservation International conducted a scoping study of cetaceans in Timor-Leste. In five days, 10 whale and dolphin species were recorded. Over 2,200 individuals were sighted. Local guides, fishermen, conservation groups and […]

Fish earbones as a tool to examine climate variability: development of a marine growth chronology – Guest blogger Gretchen Grammer

Guest post by Gretchen Grammer, Gretchen is a PhD student in the Marine Biology Program, School of Earth & Environmental Science at The University of Adelaide. Her current research centres on the use of fish otoliths as a proxy to examine oceanographic processes in relation to climate variability. She is also interested in the use […]

New Paper: Does the behaviour of a reef shark change as the water temperature changes?

A new paper titled ‘Heat-seeking sharks: support for behavioural thermoregulation in reef sharks‘ investigates shark behaviour and movement patterns in relation to thermoregulation and water temperature. The paper suggests that reef shark movements are influenced by water temperature and provides support for behavioural thermoregulation theories. This data is important for predicting how sharks might be […]

New Paper: The diving patterns of the deep-diving southern elephant seal

A new paper titled ‘Depletion of deep marine food patches forces divers to give up early‘ investigates the behaviour of deep-diving sea animals in terms of their eating habits. The paper assesses the validity of the optimal foraging theory by investigating the dive behaviour of the world’s deepest-diving seal, the sourthern elephant seal Mirounga leonina. […]
