Worldwide analysis of reef surveys sorts coral taxa by associations with recent and past heat stress

Stéphane Joost, Oliver Michele Selmoni, Véronique Berteaux-Lecellier

Coral reefs around the world are under threat from anomalous heat waves that are causing the widespread decline of hard corals. Different coral taxa are known to have different sensitivities to heat, although variation in susceptibilities have also been ob ...

Intracellular competition for nitrogen controls dinoflagellate population density in corals

Anders Meibom, Stéphane Laurent Escrig, Maoz Fine, Julia Marie Jeanne Yvonne Bodin, Maria-Evangelia Giovani

The density of dinoflagellate microalgae in the tissue of symbiotic corals is an important determinant for health and productivity of the coral animal. Yet, the specific mechanism for their regulation and the consequence for coral nutrition are insufficien ...

Seascape genomics as a new tool to empower coral reef conservation strategies: an example on north‐western Pacific Acropora digitifera

Stéphane Joost, Oliver Michele Selmoni, Estelle Rochat

Coral reefs are suffering a major decline due to the environmental constraints imposed by climate change. Over the last 20 years, three major coral bleaching events occurred in concomitance with anomalous heatwaves, provoking a severe loss of coral cover w ...

Coral cover surveys corroborate predictions on reef adaptive potential to thermal stress

Stéphane Joost, Oliver Michele Selmoni, Véronique Berteaux-Lecellier

As anomalous heat waves are causing the widespread decline of coral reefs worldwide, there is an urgent need to identify coral populations tolerant to thermal stress. Heat stress adaptive potential is the degree of tolerance expected from evolutionary proc ...

High rates of carbon and dinitrogen fixation suggest a critical role of benthic pioneer communities in the energy and nutrient dynamics of coral reefs

Nils Rädecker, Hal Hunt Jones II

Following coral mortality in tropical reefs, pioneer communities dominated by filamentous and crustose algae efficiently colonize substrates previously occupied by coral tissue. This phenomenon is particularly common after mass coral mortality following ...

Responses of reef bioindicators to recent temperature anomalies in distinct areas of the North Ari and Rasdhoo atolls (Maldives)

Arthur Adams, Aurélie Angéloz, Anaël Lehmann

Assessments of reef sediments in the North Ari Atoll (Maldives) were conducted in 2015 and 2018 on reefs of three islands with different management strategies: community, resort, and uninhabited. Indices applied were the Foraminifera in Reef Assessment and ...

Vibrio coralliilyticus infection triggers a behavioural response and perturbs nutritional exchange and tissue integrity in a symbiotic coral

Anders Meibom, Emma Mary Gibbin

Under homoeostatic conditions, the relationship between the coralPocillopora damicornisandVibrio coralliilyticusiscommensal. An increase in temperature, or in the abundance ofV. coralliilyticus, can turn this association pathogenic,causing tissue lysis, ex ...

Differential nitric oxide synthesis and host apoptotic events correlate with bleaching susceptibility in reef corals

Thomas Krüger

Coral bleaching poses a threat to coral reefs worldwide. As a consequence of the temperature-induced breakdown in coral–dinoflagellate symbiosis, bleaching can have extensive effects on reef communities. However, our understanding of bleaching at a cellula ...
