IN BRIEF
|
Around a hundred scientists are on a mission in Guadeloupe to explore the biodiversity islands of the archipelago, notably The Saintes, Marie-Galante And La Désirade. For six weeks, these researchers study both land and sea, aiming to identify new species and better understand the region’s unique ecosystems. Séphora Bajazet, a biology student, takes part in this exciting adventure where they examine small marine and terrestrial organisms, with the hope of discovering still unknown species. The project, named “The Planet revisited”, highlights the importance of preserving this exceptional biodiversity, especially in the face of threats from invasive exotic species and increasing urbanization.
Guadeloupe, with its enchanting landscapes and unique biodiversity, is attracting more and more attention on the scientific scene. Currently, an international mission, “ The Planet Revisited ”, is underway, bringing together researchers to explore the lesser-known islands of this archipelago. For six weeks, they study the biological richness of the Land, and in particular small islands like Saintes and Marie-Galante. The main objective of this mission is to collect new data on the fauna and flora, while identifying species that have not yet been documented. Immersed in the vibrant waters and turned towards the land, these expeditions are crucial to better understand and protect Guadeloupe’s biodiversity.
A crucial issue for biodiversity
Biodiversity in Guadeloupe is exceptional, but it is also threatened. Climate change, pollution, and urban sprawl weigh heavily on the natural environment. In recent decades, some species have disappeared, while others are in danger. It is in this context that the current expedition takes place. Invaluably valuable, biodiversity is key to the health of ecosystems, which provide vital services, such as water supply, crop pollination and climate regulation.
The “Planet Revisited” mission
Entitled “ The Planet Revisited », the main aim of this scientific mission is to carry out a systematic assessment of the marine and terrestrial biodiversity of the small islands of the archipelago. More specifically, researchers explore the Saintes, Marie-Galante, And La Désirade. Around a hundred scientists from various countries came together to work together, sharing their knowledge and skills in the field. During this six-week period, they carry out dives, of the hunts of species and analyzes in the field, with the hope of discovering new species and studying those at risk.
The research method
Research teams use different tools to collect data. Coral reef dives are carried out usingunderwater vacuum cleaners and of brushing baskets to collect living organisms which are then classified and analyzed. In addition, certain species are photographed, collected for DNA analyses, and documented in order to complete local biodiversity databases. The diversity of workshops and specializations in the laboratory allows a complete scientific approach, right down to the genetic analysis of the samples collected.
Fascinating discoveries
Each new dive brings its share of surprises. Researchers hope to identify currently undocumented species. Previous marine expeditions have discovered more than 300 new species along the Guadeloupean coast. The aim of this mission is to extend these discoveries to biotopes less explored. This could therefore be an opportunity to discover endemic species, which do not exist anywhere else in the world.
Fragile biodiversity
The work of scientists is all the more urgent given the fragility of the biodiversity of small islands. The double insularity of Guadeloupe means that each island has a unique evolutionary history, with faunas that can be very isolated, creating distinct ecosystems. However, this biodiversity is threatened byurbanization and the introduction of invasive exotic species, which disrupt the balance of local ecosystems. THE cats, THE chickens, and the goats, for example, represent undeniable threats to endemic fauna.
Researchers and their motivations
These researchers, passionate about biodiversity, see this mission as much more than professional experience. For them, it is an opportunity to refine their knowledge and contribute to the protection of their environment. Participating in this scientific exploration is a unique chance to see the beauty and richness of their island up close, while playing a role in the preservation of these unique natural resources.
The importance of awareness
Beyond research, education and awareness are essential to protect biodiversity. Once the results of the mission have been synthesized, it is crucial to share them with the public in order to inform and provoke interactions with nature. The objective is to motivate the community to cherish and preserve this natural heritage, which is a treasure for future generations. Understanding and appreciating biodiversity must be at the heart of local initiatives, involving residents in the protection of their environment.
An underwater treasure to preserve
The marine biodiversity of Guadeloupe is quite simply breathtaking. There we find emblematic species such as turtles, THE rays and colorful fish that inhabit the coral reefs. Underwater explorations are often unparalleled and amateur divers come from all over the world to admire these aquatic landscapes. However, these ecosystems are vulnerable to pollution, At dubious turbotating and other human activities that threaten natural habitats.
Examples of marine discoveries
Among the notable marine discoveries made during previous expeditions, species of corals known as asleep were analyzed. These corals, which play a key role in maintaining the marine ecosystem, are not only impressive with their diverse colors and sizes, but are also essential for stabilizing the seafloor and providing habitat for other species.
Predictable but essential conclusion
While research continues, the “Planet Revisited” mission is crucial to better understand the richness of Guadeloupe’s biodiversity. The dissemination of this knowledge will contribute to the need felt in all communities to act in favor of the preservation of this unique environment. By offering new light on the importance of ecosystems, scientists hope to raise awareness for a lasting protection of Guadeloupe. Each discovery, each expertise is a step closer towards a better understanding of the hidden treasures of our planet.
“We collected what we could from the tide, and now we sort by species. » What an incredible experience for these scientists on the island of Terre-de-Haut! Séphora, a biology student, enthusiastically describes how she is immersing herself in this exciting mission. “ It’s fascinating to see with my own eyes the species I’ve been studying for years. » She is totally absorbed in her work, despite the breathtaking view of the sea.
“It’s a real concentrate of biodiversity! » says Laure, a marine biology researcher. She explains that the objective of this mission is to discover and reference species that have never been seen before. “ We hope to find specimens unique to the small islands of the archipelago. » As coordinator, her determination is palpable and her enthusiasm contagious.
Olivier, professor at the university, wanders through the laboratory being installed. “Each workshop has its own theme, there are even shellfish which are the subject of special monitoring! » He emphasizes the importance of working in collaboration with other researchers from around the world. “It’s really teamwork and it’s nice to see so much passion brought together here! »
A few meters away, the director of the French Biodiversity Office, Olivier Thibault, observes an insect trap hanging from a tree. “Collecting these insects is a step towards understanding our biodiversity. » He goes on to explain that even species considered negligible, such as flies, are worth studying because they play an essential role in the ecosystem.
Another scientist, Line, recalls that “Each dive can reveal hidden treasures, such as little-known corals or rare fish species. » It expresses a sense of urgency: “It’s very hot outside, and we have to be quick to get our freshly collected samples back to the lab. » This constant competition with time highlights how valuable this work is.
These testimonies only reinforce the idea that Guadeloupe, with its rich and varied biodiversity, is a true living laboratory and a field of exploration for these passionate researchers. They all agree that “Discovering the secrets of our islands is not only a privilege, but also a responsibility. »
