Climate change impacts

Measuring marine range shifts

There are many ways to measure range shifts. Each way has its own pros and cons. Statistics help scientists find the most appropriate way to measure range shifts.

Vagrants of the sea!

As many as 47 species of juvenile tropical fish were observed along the NSW coastline by marine biologist Dr Figueira and his colleagues during the summers of 2003 and 2004.  Are these fish temporary “vagrants" or do they represent the first wave of climate-induced changes in NSW seas?

Climate change impacts on tropical fisheries

The impacts of climate change on tropical fisheries in northern Australia is being investigated by a three-year research project through the FRDC (Fisheries Research and Development Corporation).  Using existing data, the study will review how climate change affects important tropical fish species like Barramundi, Spanish mackerel and coral trout; and predict impacts on fisheries in the future. 

The impacts of climate change on south-east Australian fisheries

Australia’s south east is a climate change ‘hotspot’, with marine waters warming at more than three times the global average. Warming will affect Australia’s fisheries and aquaculture sectors in different ways, according to the El Nemo South East Australia Program (SEAP).

Phenology and physiology

Climate change can alter the timing (phenology) of life cycle events and the physiology of an organism: impacting a species' reproduction, behaviour, feeding, interactions and where they live.

Land and sea species differ in climate change response

All animals occupy a piece of real estate on this earth, known as their geographic distributional range.  Various factors contribute to determining a species’ range, but temperature is up there in importance. This article compares the reponse of land and sea animals to climate warming.

Sea urchin overgrazing and ocean warming

Dr Craig Sanderson from the Institute for Marine and Antarctic Studies (IMAS) in Hobart Tasmania discusses how longspine sea urchins are overgrazing Tasmanian rocky reefs: just one example of the impacts of ocean warming on marine ecosystems.
