Show moreBetween 10–12 November 2014, three weeks following the peak of the 2014 thermal stress event, six visibly non-bleached and six visibly bleached parent colonies of M. capitata and P. compressa were collected from 1–3m depth from the fringing reefs surrounding Moku o Loʻe in Kāneʻohe Bay (centered at 21°26’6” N, 157°47’12” W) and in Waimānalo Bay (centered at 21°19’36” N, 157°40’54” W) using a hammer and chisel. One ramet from each colony was immediately placed in a -20 °C freezer to evaluate the initial physiology of the parent colonies prior to experimental manipulation. An additional twelve ramets were collected from each parent colony of each species from each location (totaling 576 fragments) and mounted on pre-labeled plastic tiles for use in the manipulative experiment.
All experimental ramets were returned to the Hawai‘i Institute of Marine Biology and allowed to recover under ambient seawater conditions in outdoor, unfiltered, flow-through seawater tanks for three days. Natural light levels were reduced using 40% neutral density shade cloth such that photosynthetically active radiation levels mimicked that at collection depth.
On 15 November 2014, ramets were equally divided among eight outdoor, 38 L experimental tanks supplied with unfiltered, flow-through seawater. Though the incoming seawater was unfiltered, virtually no zooplankton is delivered to experimental tanks at HIMB due to scouring of the inflowing seawater by in-line invertebrates. Two experimental tanks were randomly assigned to each of the following four treatments: 1) Control (ambient seawater of pH 7.97 and unfed), 2) Fed (ambient seawater of pH 7.97 and fed), 3) OA (acidified seawater of pH 7.74 and unfed), and 4) OA+Fed (acidified seawater pH 7.74 and fed).
Coral holobiont physiology was assessed for parent colonies (i.e., in situ reef controls) and a subset of experimental corals in December 2014 (2 months after 2014 peak thermal stress; 1 month in experimental tanks), June 2015 (8 months after 2014 peak thermal stress; 7 months in experimental tanks), and November 2015 (one month after 2015 peak thermal stress; 13 months in experimental tanks).
