Dolphins of the genus Stenella occur in pelagic waters both tropical and warm-temperate oceans. Three species, Atlantic spotted dolphin (Stenella frontalis), pantropical (S. attenuata), spinner longirostris) are abundant worldwide, but Caribbean Basin they have been poorly studied information on their distribution patterns is scarce. Specifically, Colombia's remote Seaflower Biosphere Reserve (SFBR) S. attenuata has reported occasionally, frontalis longirostris never recorded before. To...
Sea turtles use specific nesting strategies to maximize the survival of their offspring. Few studies have investigated behavior leatherback (Dermochelys coriacea) and hawksbill (Eretmochelys imbricata) turtles. The aim this study was characterize these two species, taking into account anthropogenic natural impacts, compare between species. Nocturnal monitoring conducted from 2020 2024 on three beaches in Martinique: Madiana, Diamant, Salines. average duration sequence for 101.50 min, with...
Certain fish, such as rainbow trout (Oncorhynchus mykiss), are seasonal breeders. Spermatogenesis in is synchronous; therefore, at any time point during this process, germ cells predominantly the same stage of development. As such, represent an excellent model which to study spermatogenesis. Gap junctions composed connexons, themselves formed by six transmembrane proteins termed connexins (Cxs). The objectives were assess Cxs expressed testis, and if their expression was specific gonadal...
The Agoa protected marine area, located in the French West Indies, eastern Caribbean, holds several cetacean species, of which pantropical spotted dolphin Stenella attenuata is most commonly observed. This species focus whale-watching activities off leeward coasts Guadeloupe and Martinique, has allowed development a citizen science program to characterize individuals through collection photographic data. Here, we conducted photo-identification study with sample 115,705 photos collected...
The aim of this study was to better understand the molecular events governing ontogeny in winter flounder (Pseudopleuronectes americanus (Walbaum, 1792)). expression seven genes involved key metabolic processes during metamorphosis were measured at settlement (S0), 15 (S15), and 30 (S30) days after compared with those pelagic larvae prior (PL). Two critical stages identified: (1) larval transit from benthic habitat (from PL S0) (2) maturation, when stay settled without growth S0 S30). Growth...
Marine mammals are found in every sea worldwide and at the highest level of marine food chain. They communicate among themselves through sounds. It is complicated to study characterize these populations because they spend most their time below surface. Nevertheless, it possible analyze, classify different cetacean species use bioacoustics. Our focuses on Pantropical spotted dolphin (Stenella attenuata), particular influence nautical tourism, i.e. whale-watching boats, Caribbean Sea...
Metamorphosis is a critical developmental stage in marine fish species, but mortalities are also elevated at the settling phase. Our objective was to evaluate effects of different rearing systems and larval diets on survival, general condition pigmentation newly settled winter flounder (Pseudopleuronectes americanus) juveniles. At settlement, juveniles were reared two types tanks (plankton kreisel rectangular raceway). The early followed for 1 month their evaluated using biochemical indices....
The pantropical spotted dolphin (PSD, Stenella attenuata) is the most common cetacean species observed within Agoa Sanctuary, located in Lesser Antilles, Eastern Caribbean. These dolphins are easily observable and main target of whale-watching activities along leeward coasts Guadeloupe Martinique islands. Because PSD sanctuary it considered a resident species, however, no research has been carried out to estimate its population status movement patterns between Previous unpublished work found...
Although human activities are developing in French Guiana Exclusive Economic Zone (EEZ) and surrounding countries, knowledge on diversity ecology of cetaceans the region is scarce. This study aimed to collect new information cetacean species occurring year-round entire EEZ by combining visual acoustic data obtained from three boat-based campaigns conducted local NGOs. The GEPOG campaign was July 2011 June 2012, four days every two months; COHABYS performed five per month January May 2018;...
The short-finned pilot whale (Globicephala macrorhynchus) is distributed throughout the Caribbean and within Agoa Sanctuary, where it protected. This top predator overlooked in Caribbean, no data available on variability of degree fidelity to islands, or even demographic parameters social structure this species, which essential for its conservation understanding behavior. study focuses islands Guadeloupe Martinique based 24,374 photos collected between 2014 2022. was analyzed using CMR...
The countries of the Caribbean basin are regularly subjected to intense climatic events such as hurricanes. In early July 2024, Hurricane Beryl became earliest Category 4 hurricane on record, striking Martinique with unprecedented intensity. These extreme weather pose a significant threat breeding success endangered sea turtles in Caribbean. main objective this research was determine direct impact nesting populations Leatherback (Dermochelys coriacea) and Hawskbill (Eretmochelys imbricata)....

Chez la Tortue verte (Chelonia mydas (Linnaeus, 1758)), plupart des estimations d’abondance reposent sur une phase du cycle, nidification. Or, le suivi tendances démographiques chez les juvéniles s’avère essentiel pour mettre en œuvre mesures de gestion précoces. Dans cette étude, nous avons effectué estimation l’abondance Tortues vertes présentes long côte Caraïbe Martinique. Les données ont été récoltées six mois (de janvier à juillet 2019), base modèle capture-marquage-recapture par...
The invasive alien species Pterois sp. has strongly invaded the Western Atlantic and Caribbean Sea since 1980s. Many studies have been set up to monitor this species. This study is first carry out a follow-up of these populations by capture-marking-recapture with photo-identification in natural environment. monitoring was carried over period five months at two sites south Martinique. technique showed high efficiency method important recapture rates (36.51% on Acropora 43.59% Trois Rivières)....
