Abstract:
Given the substantial warm-water induced bleaching experienced by Florida Keys corals in fall 2014, and substantial heat stress already experienced in June-July 2015, expectations for spawning in 2015 were somewhat low. The dates of the full moon (31 July and 29 August) also raised additional uncertainties for timing of potential spawning. Despite these uncertainties, SEFSC and partners documented at least some Acropora spawn in Aug 2015 (3 sites) but none in Sept (only one site observed). Meanwhile, this was the second year that we attempted genet-specific spawning observations for Orbicella faveolata. Although two sites were genotyped in 2014, observations were possible only at Horseshoe Reef (3 nights each in Aug and Sept). The genotyped population at Horseshoe is only slightly clonal; approximately 35 colonies comprising 28 genets were observed. Approximately 19 of these genets spawned at least some in August. In September, four of these genets spawned again (mostly on 5 Sept), along with one additional genet that had not spawned in August. Hence, eight of the 28 observed O. faveolata genets did not spawn.
