“…Other studies, not concerning parental diet, can offer an insight. POI was reported as stable in Montipora capitata eggs from Hawaii, as lipid reserves and antioxidant defense were equal between high light and shaded reefs despite adult plasticity (Padilla‐Gamiño et al, ). Contrastingly, variable POI was displayed in multiple coral species with higher lipid reserves allocated to larvae from healthier coral populations with higher benthic cover in Curacao (Hartmann, Marhaver, & Vermeij, ).…”

Successful reproductive output and recruitment is crucial to coral persistence and recovery following anthropogenic stress. Feeding is known to alter coral physiology and increase resilience to bleaching.The goal of the study was to address the knowledge gap of the influence of feeding on reproductive output and offspring phenotype.Colonies of Stylophora pistillata from the Northern Gulf of Aqaba (Red Sea) were fed an Artemia diet or unfed for 5 months during gametogenesis, fertilization, and brooding. In addition, time to settlement and mortality of planulae were assessed at water temperatures ranging from winter temperature (22°C) to three degrees above average peak summer temperature (31°C). A range of physiological parameters was measured in parents and offspring.In brooding parents, feeding significantly increased protein concentration and more than tripled the number of released planulae. Planulae from unfed colonies had higher chlorophyll per symbiont concentration and concomitantly higher photosynthetic efficiency compared to planulae from fed parents. In settlement assays, planulae showed a similar thermal resistance as known for this Red Sea adult population. Mortality was greater in planulae from unfed parents at ambient and 3°C above ambient temperature despite higher per offspring investment in terms of total fatty acid content. Fatty acid profiles and relative abundances were generally conserved between different fed and unfed colonies but planulae were enriched in monounsaturated fatty acids relative to adults, that is, 16:1, 18:1, 20:1, 22:1, and 24:1 isomers.Ultimately the availability of zooplankton could influence population physiology and recruitment in corals.

“…Alternative drivers of population variation in thermal tolerance are long-term acclimatory mechanisms such as parental effects, where offspring phenotypes are influenced by the environment of their parents (Mousseau and Fox 1998). The only investigation of parental effects on thermal tolerance in corals found no difference in egg properties (energy reserves and antioxidant defences) in Montipora capitata from neighboring reef sites with distinct temperature and light profiles (Padilla-Gamin˜o et al 2012); however, parental effects can influence thermal tolerance in other tropical marine organisms (Donelson et al 2011). …”

Abstract. Knowledge of the degree to which corals undergo physiological acclimatization or genetic adaptation in response to changes in their thermal environment is crucial to the success of coral reef conservation strategies. The potential of corals to acclimatize to temperatures exceeding historical thermal regimes was investigated by reciprocal transplantation of Acropora millepora colonies between the warm central and cool southern regions of the Great Barrier Reef (GBR) for a duration of 14 months. Colony fragments retained at native sites remained healthy, whereas transplanted fragments, although healthy over initial months when temperatures remained within native thermal regimes, subsequently bleached and suffered mortality during seasonal temperature extremes. Corals hosting Symbiodinium D transplanted to the southern GBR bleached in winter and the majority suffered whole (40%; n ¼ 20 colonies) or partial (50%) mortality at temperatures 1.18C below their 15-year native minimum. In contrast, corals hosting Symbiodinium C2 transplanted to the central GBR bleached in summer and suffered whole (50%; n ¼ 10 colonies) or partial (42%) mortality at temperatures 2.58C above their 15-year native maximum. During summer bleaching, the dominant Symbiodinium type changed from C2 to D within corals transplanted to the central GBR. Corals transplanted to the cooler, southern GBR grew 74-80% slower than corals at their native site, and only 50% of surviving colonies reproduced, at least partially because of cold water bleaching of transplants. Despite the absence of any visual signs of stress, corals transplanted to the warmer, central GBR grew 52-59% more slowly than corals at their native site before the summer bleaching (i.e., from autumn to spring). Allocation of energy to initial acclimatization or reproduction may explain this pattern, as the majority (65%) of transplants reproduced one month earlier than portions of the same colonies retained at the southern native site. All parameters investigated (bleaching, mortality, Symbiodinium type fidelity, reproductive timing) demonstrated strong interactions between genotype and environment, indicating that the acclimatization potential of A. millepora populations may be limited by adaptation of the holobiont to native thermal regimes.

Reef-building corals inhabiting the mesophotic zone (30−150 m) not only survive but thrive in light-limiting environments. Similar to shallow corals, mesophotic corals also exhibit coral fluorescence. Because fluorescent proteins (FPs) absorb high-energy light and emit lowerenergy light, FPs could play an important role in mesophotic coral physiology and ecology. For 4 species of the Hawaiian mesophotic reef-building coral Leptoseris (65−125 m), we investigated the abundance of fluorescent morphs, types of FPs, fluorescence emission phenotypes, and the physiological relationship between coral fluorescence and endosymbiotic Symbiodinium (dinoflagellate; Dinophyta). Cyan/green coral fluorescence emission was widespread in mesophotic Leptoseris spp.; more than 70% of corals fluoresced, yet fluorescent and nonfluorescent corals cooccurred at all depths investigated. Coral fluorescence was attributed to 2 proteins, a cyan fluorescent protein (CFP, λ ex = 424 nm, λ em = 490 nm) and a green fluorescent protein (GFP, λ ex = 478 nm, λ em = 502 nm). The type of FP in Leptoseris colonies was correlated with depth; CFP was dominant in corals from shallower depths (65−85 m), GFP was dominant in corals from deeper depths (96−125 m), and CFP and GFP were present in corals from middle depths (86−95 m). Coral FP emission was primarily localized in the coenosarc and/or the oral disc. Symbiodinium from corals with and without fluorescence emission had similar genotypes, abundances, photosynthetic pigments, photosynthetic efficiencies, photosynthetic rates, and chlorophyll excitation spectra. As such, it is unlikely that these FPs play a significant role in enhancing symbiont photosynthesis. The high abundance of fluorescent morphs (> 70%) dominating this energetically limited environment may suggest that FPs play an integral and conserved physiological role in corals.
