On the need to consider multiphasic sensitivity of marine organisms to climate change: a case study of the Antarctic acorn barnacle
Abstract Aim Species distribution models ( SDM s) are routinely employed to evaluate shifts in the geographic distributions of organisms in response to changing climatic conditions. Many marine invertebrates exhibit a biphasic life cycle: benthic adults and planktonic larvae, which inhabit different...
