Revisiting the footprints of climate change in Arctic marine food webs: An assessment of knowledge gained since 2010
In 2011, a first comprehensive assessment of the footprints of climate change on Arctic marine ecosystems (such as altered distribution ranges, abundances, growth and body conditions, behaviours and phenologies, as well as community and regime shifts) was published. Here, we re-assess the climate-dr...
