Photobiology of corals from Brazil's near-shore marginal reefs of Abrolhos

Journal Article


Abstract


  • Coral communities were examined from highly

    turbid near-shore marginal reefs of Abrolhos (Brazil) to

    test a paradigm previously developed from observations in

    clear water reefs; specifically, that coral photobiological

    properties follow a highly conserved linear relationship

    with optical depth (f) via preferential ‘non-photochemical’

    over ‘photochemical’ dissipation of absorbed light energy.

    PAM flourometry in situ was used to examine the photobiology of the most dominant coral species throughout the

    platform surfaces and bases of Abrolhos’ characteristic

    ‘chapeiroes’ reef framework; however, none of the species

    consistently adhered to the ‘clear water paradigm’. PAM

    measurements further demonstrated that species conformed

    to two different strategies of non-photochemical energy

    dissipation: transient but relatively rapid for the two closely

    related endemic species (Mussismilia braziliensis and

    Mussismilia harttii) as opposed to more persistent for

    Montastrea cavernosa, Porites astreoides and Siderastrea

    stellata. Further experiments demonstrated that tolerance to

    anomalous stress amongst species did not correspond with

    the non-photochemical energy dissipation strategy present

    but was consistent with the relative dominance of species

    within the chapeiroes coral communities.
