Gorgonians' Thermal History Dictates Their Response to Warming
Linares, C., Cebrian, E., Kipson, S. and Garrabou, J. 2013. Does thermal history influence the tolerance of temperate gorgonians to future warming? Marine Environmental Research 89: 45-52.
In discussing their findings, the four researchers report "E. singularis populations from both areas exhibited a high resistance to thermal stress." However, they found "populations from warmer areas had an increased tolerance to thermal stress," such that "the upper thermal limits found for cold and warm populations were 28 and 29°C, respectively."
Linares et al. conclude their study by noting their results "agree with results for other Mediterranean anthozoans (Rodolfo-Metalpa et al. 2006; Torrents et al., 2008) and tropical corals (Middlebrook et al., 2008), demonstrating thereby that shallow populations (acclimated to warm temperature conditions) have a higher tolerance to thermal stress than deep populations."
