“…& Gattuso, 2019; Movilla et al, 2014), the projected shoaling of the calcite and aragonite saturation horizons along with warming is expected to lead to the loss of suitable habitat (Davies & Guinotte, 2011;Perez et al, 2018;Sulpis et al, 2018;Tittensor et al, 2010;Yesson et al, 2012), weakening of the reef frameworks that may result in structural collapse of slow-growing scleractinian corals (Büscher et al, 2019;Gomez, Wickes, Deegan, Etnoyer, & Cordes, 2019;Hennige et al, 2015), and increased mortality of octocorals that form coral gardens (Cerrano et al, 2013;Gugliotti, DeLorenzo, & Etnoyer, 2019). Notwithstanding genotypic variability in cold-water corals' response to ocean acidification (Kurman, Gómez, Georgian, Lunden, & Cordes, 2017;Lunden, McNicholl, Sears, Morrison, & Cordes, 2014), these changes may result in the loss of biodiversity and provision of ecosystem services associated with these ecosystems .…”
