As mentioned earlier, we had the unfortunate opportunity to dive at Peros Banhos both before (30˚C) and during (31˚C) a bleaching event. Had I known we would have this opportunity, I would have tagged colonies to be sampled twice. Unfortunately, the best I’ve got is corals from the same reef sampled at both times (n=4 sites: 69, 70, 72, and 74). I am going to analyze the proteomes of P. acuta colonies sampled before and during bleaching in 2019, and it is worth noting that not all colonies had bleached upon our return in late April and early May. I also have a mix of S. hystrix samples that did (n=7) or did NOT (n=20) resist bleaching (latter sampling time only).

Sites 69, 70, 72, and 74 were all sampled+surveyed both before and during a bleaching event.

BiPb110 (2015-04-30) This was out first dive to this leeward lagoonal channel where, where one P. damicornis (ChPd150) and one Seriatopora sp. (ChSe156) were sampled.

BiPb70b (2015-05-1) Our first re-visit to a badly bleaching leeward lagoonal patch reef site. Five P. damicornis (ChPd151-155) and three Seriatopora spp. (ChSe157-159) were sampled; although none of the P. damicornis colonies had bleached, all of the seriatoporids had. Also note that, although the pocilloporids were genotyped via RFLP as P. damicornis, they certainly look like P. acuta.

BiPb72b (2015-05-1) A re-visit to a series of badly bleaching back reef pinnacles. Two P. damicornis (ChPd156 [bleached] and ChPd157 [unbleached]) and five Seriatopora spp. (ChSe160-164) were sampled; although only one of the two P. damicornis colonies had bleached, all five seriatoporids had (ChSe163 being the exception). Also note that, although the pocilloporids were genotyped via RFLP as P. damicornis, they certainly look like P. acuta.

BiPb74b (2015-05-1) A re-visit to a badly bleaching leeward lagoonal patch reef. Three unbleached P. damicornis (ChPd158-160) and one completely bleached Seriatopora sp. (ChSe165-the only one seen at the site) colonies were sampled. Note that, although the pocilloporids were genotyped via RFLP as P. damicornis, they certainly look like P. acuta.

BiPb111 (2015-05-01) did not dive at this leeward lagoonal channel reef.

BiPb69c (2015-05-02) Our third dive to this leeward lagoonal patch reef (the first during the bleaching event). Six P. acuta/damicornis (ChPd161-166) and five Seriatopora spp. (ChSe166-170) colonies were sampled.
