Seabirds supply nitrogen to reefbuilding corals on remote Pacific islets

Seabirds concentrate nutrients from large marine areas on their nesting islands playing an important ecological role in nutrient transfer between marine and terrestrial ecosystems. Here we investigate the role of guano on corals reefs across scales b...

Tracking trace elements into complex coral reef trophic networks

Humans and climate variability threaten large-bodied endemic fishes on coral reefs.

Modeling and computational tools for coral reef management and conservation.

Society-based solutions to coral reef threats in french pacific territories

This article reviews the state of coral reefs in French Pacific territories in the context of global change (especially threats linked to climate change). We first outline the specific local characteristics, vulnerabilities, and threats faced by the ...

Artificial coral reefs, electrochemistry and calcium carbonate: electrodeposited coral-like aragonite

Coral reef degradation alters the isotopic niche of reef fishes.

Enhancement of coral calcification via the interplay of nickel and urease

Corals are the main reef builders through the formation of calcium carbonate skeletons. In recent decades, coral calcification has however been impacted by many global (climate change) and local stressors (such as destructive fishing practices and ch...

Nickel and ocean warming affect scleractinian coral growth

The sensitivity of corals and their Symbiodinium to warming has been extensively documented; however very few studies considered that anthropogenic inputs such as metal pollution have already an impact on many fringing reefs. Thus, today, nickel rele...

Evidence for mitigation of coral bleaching by manganese

Unprecedented mass coral bleaching events due to global warming and overall seawater pollution have been observed worldwide over the last decades. Although metals are often considered as toxic substances for corals, some are essential at nanomolar co...
