WESTERN Australian researchers are conducting a global initiative to evaluate the importance of sharks for conservation and economic development, in a bid to slow global declines in shark numbers.
AN INVASIVE fish species currently occupying the Chapman River is being monitored in research exploring the effectiveness of different capture methods.
THE immense diversity of sponge species in West Australian waters has been celebrated at the 9th World Sponge Conference earlier this month.
THE WA coastline is well known for banks of marine vegetation called ‘beach wrack’ that accumulates on beaches—but its role in coastal ecosystem health is not completely understood.
WHILE Dirk Hartog Island is the southernmost rookery for loggerhead turtles, UWA and Murdoch University biologists say climate change may ultimately lead to the species nesting successfully on beaches further south.
CORAL cover patterns along the WA coast have remained relatively stable over the last 25 years, according to recent meta-analytical research.
RESEARCH from scientists at UWA’s Oceans Institute has filled the gap in understanding electrosensory systems in estuary stingrays.
RESEARCHERS investigating the Ningaloo Reef’s circulation patterns have discovered that periodic, local wind-driven currents are still strong enough to generate upwelling, providing important nutrients from the seabed to the reef, despite strong suppression from the Leeuwin Current.
NOCTURNAL fish at the Houtman Abrolhos Islands, off Geraldton are at the centre of research that has found the type of lighting chosen to survey them influences their behaviour and abundance.
A THOROUGH re-examination of fossil collections shows the modern Great White shark (Carcharodon carcharias) is not closely related to the extinct “Megatooth” shark (Carcharocles megalodon), as was previously believed.
CLIMATE change will threaten the survival of marine mammals according to researchers investigating the impact of rising air and sea surface temperatures on Australia’s ocean dwelling mammals.
AN Australian Antarctic researcher visited Geraldton, this May, as a part of the WA Museum's series of public lectures.
CORAL responses to ocean temperatures and currents during the 2010-11 marine heatwave have been recorded in research that has found WA’s coral reefs may be more vulnerable to irregular warming events than previously thought.
SCIENTISTS researching light stress indicators in seagrass have gathered and analysed international research in the field to narrow-down 119 variables to 19 robust bioindicators of light stress that can be incorporated into monitoring programs.
AN INVESTIGATION by UWA scientists into factors which affect eye size in certain deep-sea fish has found that eye size varies based on the individual fish’s evolutionary status, rather than ecological pressures.
THE Western Australian Department of Fisheries have embarked on an intensive research and monitoring program into the declining numbers of blue swimmer crabs (Portunus armatus) in Shark Bay.
AUSTRALIA is leading the world in regulating shark based tourism according to new research.
A RECENT study has not only shed light on the charismatic Nautilus pompilius, but has also illustrated the success of using DNA barcoding as a tool to identify geographic origins, and to study population genetics and evolutionary biology.
PHOTOGRAPHS from public online databases can provide data to make accurate estimations of whale shark populations according to new research.
SHARK embryo research from UWA’s Oceans Institute has determined embryos can remember previously encountered predator-like stimulus and reduce their response to it, creating implications for the effectiveness of electric shark repellents.
