We studied the effect of chronic oxybenzone exposure and elevated temperature on coral health. Microcolonies of Stylophora pistillata and Acropora tenuis were cultured in 20 flow-through aquaria, of which 10 were exposed to oxybenzone at a field-relevant concentration of ~0.06 μg L−1 at 26 °C. After two weeks, half of the corals experienced a heat wave culminating at 33 °C. All S. pistillata colonies survived the heat wave, although heat reduced growth and zooxanthellae density, irrespective of… Expand
Challenges in Current Coral Reef Protection – Possible Impacts of UV Filters Used in Sunscreens, a Critical Review
Coral reefs are highly endangered ecosystems. The identification and quantification of potential stress factors are essential to protect them. UV filters from sunscreens that are introduced to coralExpand
Robust natural ultraviolet filters from marine ecosystems for the formulation of environmental friendlier bio-sunscreens.
The harmful effects of UVR and the mechanisms that microalgae have developed to cope with it are discussed and the biological distribution, characteristics, extraction, and purification methods of MAAs and scytonemin molecules are focused on to assess its potential as new filters for sunscreen formulation.

Toxic effects of UV filters from sunscreens on coral reefs revisited: regulatory aspects for “reef safe” products
Background Tropical coral reefs have been recognized for their significant ecological and economical value. However, increasing anthropogenic disturbances have led to progressively declining coralExpand
The EU Green Deal's ambition for a toxic-free environment: filling the gap for science-based policy making.
It is concluded that environmental scientists have the tools to address the key challenges presented in the Chemicals Strategy for Sustainability, but an extra step is needed by both policymakers and scientists to make these applicable. Expand


Herbicides increase the vulnerability of corals to rising sea surface temperature
Mixed model analyses of variance showed that the effects of elevated sea surface temperatures (SST) and herbicide on photosynthetic efficiency of coral symbionts were additive and effective management of local water quality can reduce negative effects of global stressors such as elevated SST.

Toxicopathological Effects of the Sunscreen UV Filter, Oxybenzone (Benzophenone-3), on Coral Planulae and Cultured Primary Cells and Its Environmental Contamination in Hawaii and the U.S. Virgin Islands
Oxybenzone poses a hazard to coral reef conservation and threatens the resiliency of coral reefs to climate change, and is a skeletal endocrine disruptor to corals. Expand
Temperature Stress Causes Host Cell Detachment in Symbiotic Cnidarians: Implications for Coral Bleaching.
The detachment and release of intact host cells suggests that thermal stress causes host cell adhesion dysfunction in these cnidarians and provides insight into both the underlying release mechanism and the way in which natural environmental stresses evoke a bleaching response. Expand
Additive effects of the herbicide glyphosate and elevated temperature on the branched coral Acropora formosa in Nha Trang, Vietnam
The results suggest that the corals in Nha Trang bay have adapted to the ongoing pollution to become more tolerant to anthropogenic stressors, and that multiple stressors hamper this resilience. Expand
The effects of elevated temperature on the photosynthetic efficiency of zooxanthellae in hospite from four different species of reef coral: a novel approach
Fundamental differences in the physiology of the symbionts within different species of coral are identified, with zooxanthellae within M. annularis appear to be more susceptible to heat-induced damage at or near the reaction centre of Photosystem II, while zooxanhellae living in S. radians remain capable of dissipating excess excitation energy through non-photochemical pathways, thereby protecting the photosystem from damage during heat exposure.

The significance of pollution in eliciting the "bleaching" response in symbiotic cnidarians
The loss of pigmentation, or "bleaching", in tropical reef organisms such as corals and symbiotic sea anemones has been extensively reported around the world over the last 15 years. The widespreadExpand
Photoinhibition from chronic herbicide exposure reduces reproductive output of reef-building corals
This is the first study to investigate the sub-lethal effects of chronic herbicide-induced photoinhibition on symbiotic corals and provides evidence of a link between reduced energy acquisition due to PSII photoin inhibition and reduced reproductive output in zooxanthellate corals. Expand
Photosynthetic response to elevated temperature in the symbiotic dinoflagellate Symbiodinium microadriaticum in culture.
Results indicate that photosynthesis is impaired at temperatures above 30 degrees C and ceases completely at 34-36 degrees C, and possible mechanisms that may function in the disassociation of algal-invertebrate symbioses in response to elevated temperature are discussed. Expand
Response of holosymbiont pigments from the scleractinian coral Montipora monasteriata to short-term heat stress
The results indicate that, during the early stages of thermal stress, thylakoid membranes are intact and support the importance of coral pigments for the regulation of the light environment within the host tissue. Expand
Sunscreens Cause Coral Bleaching by Promoting Viral Infections
It is concluded that sunscreens, by promoting viral infection, potentially play an important role in coral bleaching in areas prone to high levels of recreational use by humans. Expand
