Climate driven substitution of habitat forming species leads to reduced biodiversity within a temperate marine community
Anthropogenic climate change is a threat to marine ecosystems. The upper layers of the ocean have warmed by 0.11degC per decade since the mid20th century (IPCC, 2013) and are now on average more acidic and less oxygenated and have altered salinity and wave regimes (Bijma, Portner, Yesson, Rogers, 2013; IPCC, 2013) Ocean warming, in particular, has resulted in a global redistribution of species with biogeographic ranges generally shifting polewards in line with changing isotherms (Burrows et al. 2011; Received: 19 October 2017 Revised: 19 April 2018 Accepted: 20 April 2018 DOI: 10.1111/ddi.12775
