Exposure to solar radiation increases damage to both host tissues and algal symbionts of corals during thermal stress (2004, background): “There is substantial evidence that PSII is already affected directly by high solar radiation without any thermal stress (Gorbunov et al. 2001) and that thermal stress without high solar irradiances effects PSII (Warner et al. 1999).”
Photobiology of Symbiodinium revisited: bio-physical and bio-optical signatures (2009, methodology): “Non-photochemical quenching, NPQ, was calculated as (Fm ‐ Fm0 )/ Fm0 , and informed of the quantum yield of non-photo- chemical quenching ( Gorbunov et al. 2001 ).”
Photoinhibition in shallow‐water colonies of the coral Stylophora pistillata as measured in situ (2003, methodology): “The only measurements performed so far under such conditions were done with a fast repetition rate (FRR) fluorometer (Gorbunov et al. 2001; Lesser and Gorbunov 2001).”
Testing the photoinhibition model of coral bleaching using chemical inhibitors (2004, background): “…routinely experience photoinhibition similar to other marine photoautotrophs (Brown et al. 1999, Hoegh-Guldberg & Jones 1999, Ralph et al. 1999, Gorbunov et al. 2001) In the context of these studies, the term ‘photoinhibition’ was used to reflect light-dependent and often rapidly reversible…”
Experimental biology of coral reef ecosystems (2004, methodology): “Damage or impairment of PSII function is easily detected using nondestructive active chlorophyll fluorescence techniques (Brown et al., 1999; Jones et al., 1998; Gorbunov et al., 2001; Warner et al., 1999; Winters et al., 2003).”
Evaluation of biophysical and optical determinations of light absorption by photosystem II in phytoplankton (2004, background): “5 to 3 across a range of temporal and spatial scales (Greene et al. 1994; Vasiliev et al. 1994; Behrenfeld et al. 1996; Behrenfeld and Kolber 1999; Gorbunov et al. 2001).”
Spatial heterogeneity in active chlorophyll fluorescence and PSII activity of coral tissues (2002, unknown): “Scleractian corals have been investigated in a number of recent studies using PAM fluorometry (Warner et al. 1996; Beer et al. 1998; Jones et al. 1998; Hoegh-Guldberg and Jones 1999; Ralph et al. 1999), as well as fast-repetitionrate fluorometry ( Gorbunov et al. 2000, 2001 ).”
PSII photoinhibition and photorepair in Symbiodinium (Pyrrhophyta) differs between thermally tolerant and sensitive phylotypes (2010, background): “For example, the ability of the algal symbionts to photoacclimatise to low photon flux densities (PFDs) constrains the lower depth distribution of corals (Gorbunov et al. 2001).”
The physiological response of reef corals to diel fluctuations in seawater temperature (2011, background): “026 inhibition (damage to the photosynthetic apparatus), or reversible photoinhibition (Gorbunov et al., 2001).”
Multiple scattering on coral skeletons enhances light absorption by symbiotic algae (2005, background): “…and Trench 1994) and the use of highly sensitive and nondestructive chlorophyll a (Chl a) fluorescence techniques (Hoegh-Guldberg and Jones 1999; Gorbunov et al. 2001; Warner et al. 2002; Iglesias-Prieto et al. 2004), coral photobiology has experienced significant developments over the last…”
Cell death and degeneration in the symbiotic dinoflagellates of the coral Stylophora pistillata during bleaching (2004, background): “…routinely experience short-term photoprotective down- 123 Mar Ecol Prog Ser 272: 117–130, 2004124 Franklin et al.: Symbiont mortality during coral bleaching regulation of photosynthesis in symbio, as do the majority of marine photoautotrophs (Hoegh-Guldberg & Jones 1999, Gorbunov et al. 2001).”
Energetic cost of photoinhibition in corals (2006, background): “However, chronic photoinhibition has also been reported, with up to 30% of photosynthetic reaction centers damaged by exposure to full sunlight in shallow waters (see Gorbunov et al. 2001).”
The ecological distribution and comparative photobiology of symbiotic dinoflagellates from reef corals in Belize: Potential implications for coral bleaching (2006, background): “These include down-regulation of PSII reaction centers as well as energy dissipation via nonphotochemical pathways originating in the light-harvesting antennae, such as the reduction in the functional absorption cross section (s) of PSII through an active xanthophyll cycle (Brown et al. 1999; Gorbun”
In situ photobiology of corals over large depth ranges: A multivariate analysis on the roles of environment, host, and algal symbiont (2008, background): “Photosynthetic processes such as NPQ have been commonly investigated by means of fluorescence measurements of photosystem II (PSII), which are remarkably informative regarding processes that affect both the light-harvesting antennae and electrontransfer chains (Gorbunov et al. 2001; Iglesias-Prieto ”
Chlorophyll Fluorescence in Reef Building Corals (2010, background): “Likewise, studies with corals have confirmed that rapidly reversible NPQ in the light-harvesting antennae is associated with the xanthophyll cycle, whereby a rapid conversion of diadinoxanthin to diatoxanthin occurs, which is thought to direct photon energy away from the light harvesting antennae up”
