We have experimented eDNA as a new technique for species and ecosystems monitoring. As part of the French Coral Reef Initiative (IFRECOR), fish communities have been monitored since 2001 in Martinique (oldest station: Pointe Borgnesse at Le Marin).
About 128 species have been observed, counted and size-estimated on coral reefs stations, and 58 species on seagrass beds so far. However, with a limited time underwater, and a relatively small sampled area, there are many fish species that we do not see, or miss, like cryptic, rare or migrating species. With new techniques like environmental DNA, we can “see” those species, have a better snapshot of the fish community, and understand better the link with coastal changes.
Check out our video of the first mission in Martinique where the team sampled environmental DNA on coral reefs and seagrass beds, and stay tuned for the upcoming results !
Can small mangrove forests be monitored from space?
The decline of mangrove forests worldwide is concerning because these ecosystems offer crucial benefits for both nature and people. They boost biodiversity, shield coastlines, store carbon, and support local fisheries. In the Caribbean, mangroves have suffered in the past twenty years from coastal development, population growth, and climate change. This
Cladocora caespitosa: a temperate coral growing in a climate change hotspot
Adaptation has become the centre of Small Island States’ (SIS) political response to cope with the impacts of climate change. Efforts to mainstream coastal adaptation policy among different sectors and improved access to international funds to meet adaptation costs have led to an increase in the number of adaptation projects. For
La Ville de Nice a participé au meeting MaCoBioS sur la défense des écosystèmes côtiers marins
On 17 and 18 May, Nice took part in the annual meeting of MaCoBioS, a European programme for the protection of marine coastal ecosystems, organised by the Institut Océanographique Paul Ricard (IOPR) on the island of Les Embiez.
Working with practitioners to better understand marine and coastal Nature-based Solutions
People have long benefitted from marine and coastal ecosystems. But despite this many marine and coastal ecosystems are degrading or disappearing from many places around the world. Nature-based Solutions (NBS) aim to provide societal and ecological benefits by recognising the vital role of nature to help address societal challenges, including
