Changes in marine ecosystems going undetected

Existing ways of calculating biodiversity dynamics are not very effective in detecting wholesale species community change due to the effects of ocean acidification. University of Adelaide research shows that in cases where biodiversity metrics show no change or little change, there may still be reorganisation of ecological communities in our oceans. "The belief that climate change will alter global marine biodiversity is one of the most widely accepted," said Professor Ivan Nagelkerken from the University of Adelaide's Environment Institute and Southern Seas Ecology Laboratories. "Commonly used biodiversity measures don't pick up reorganisation of marine communities due to ocean acidification because new species replace species that are lost. "Little or no biodiversity change is detected when one community of marine species is replaced by another...

Climate change may impact marine environments more than anything else

Promoting the sustainable development of marine environments requires planning, just as we have long had spatial planning for land-based activities. Now researchers from the University of Gothenburg and elsewhere are showing that marine planning must take climate change into consideration -- something that it does not currently do. The researchers' models show that changes to temperature and salt content may impact ecosystems and species as much as all other effects on the environment combined. Symphony is a digital tool that has existed for the past few years. It uses GIS maps that show the distribution of important ecosystems and species along Sweden's coastlines and how by environmental disturbances, such as nutrient pollution, boat traffic and fishing, affect them in different areas....
