Are Zooxanthellae Really Sensitive? Response of Zooxanthellae Size Exposed to Several Pollutants

open access: yesILMU KELAUTAN: Indonesian Journal of Marine Sciences, 2017
Pollution is one of the important issues faced by marine resources including zooxanthellae, which is known to be very sensitive to environmental changes. Some pollutants have been reported to have adverse effects on zooxanthellae, however, their sensitivity in regards to changes on cell size of these algae has not been widely explored.

δ<sup>13</sup>C as a Continuum: Tissue-Based, Ontogenetic, and Interspecific Variation in Carbon Sourcing of a Photosymbiotic Bivalve (Subfamily Fraginae). [PDF]

open access: yesEcol Evol
Relationship between Fragum unedo shell height (mm) and tissue δ13C. Points are color coded by shell size categories (small, medium, big) with symbol shapes representing the types of tissues (foot, mantle, or gill). ABSTRACT Photosymbiotic marine invertebrates derive carbon from both symbiont photosynthesis and heterotrophic feeding, yet the relative ...

Resolving widespread and endemic dinoflagellates (Symbiodiniaceae) mutualistic with Indo-Pacific octocorals reveals differences in specificity based on host phylogeny. [PDF]

open access: yesJ Phycol
Abstract Endosymbionts in the dinoflagellate family Symbiodiniaceae can form mutualisms with a diverse array of host invertebrates, constituting a widespread and ecologically important family. While those associated with reef‐building corals (order Scleractinia) have received considerable research attention, the diversity and ecology of zooxanthellae ...

Response and Plasticity of a Cleaning Mutualism Following Short Term Reductions in Habitat Availability. [PDF]

open access: yesEcol Evol
On coral reef ecosystems, cleaning mutualisms where a ‘cleaner’ species removes parasites from a ‘client’ species at dedicated cleaning ‘stations’ on live coral are directly impacted by ongoing declines in live coral due to environmental change. We reduced cleaner fish access to live habitat and identified declines in mutualist service quality and ...

Oxygen Deprivation Implicated in Rapid Coral Mortality Under Acute Heating Events. [PDF]

open access: yesGlob Chang Biol
When corals were exposed to rapid heating, oxygen around their tissues fell sharply before the tissues broke down and the corals died. Similar tissue breakdown occurred when corals were deprived of oxygen without heating, while stronger water flow delayed the damage by improving oxygen delivery.

Breakdown of the coral-algae symbiosis: towards formalising a linkage between warm-water bleaching thresholds and the growth rate of the intracellular zooxanthellae [PDF]

open access: yesBiogeosciences, 2013
Impairment of the photosynthetic machinery of the algal endosymbiont ("zooxanthellae") is the proximal driver of the thermal breakdown of the coral-algae symbiosis ("coral bleaching"). Yet, the initial site of damage, and early dynamics of the impairment

Growth and Extracellular Carbonic Anhydrase Activity of Zooxanthellae Symbiodinium sp. in Response of Zinc Enrichment

open access: yesHayati Journal of Biosciences, 2011
Coral reef communities contain a wide variety of mutualistic associations none more important than the relationship between corals and their symbiotic dinoflagellates of the genus Symbiodinium sp., commonly referred to as zooxanthellae.

Red light represses the photophysiology of the scleractinian coral Stylophora pistillata. [PDF]

open access: yesPLoS ONE, 2014
Light spectrum plays a key role in the biology of symbiotic corals, with blue light resulting in higher coral growth, zooxanthellae density, chlorophyll a content and photosynthesis rates as compared to red light.
