Sea turtles are an iconic group of marine megafauna that have been exposed to multiple anthropogenic threats across their different life stages, especially in the past decades. This has resulted population declines, and consequently many sea turtle populations now classified as threatened or endangered globally. Although some worldwide showing early signs recovery, still face fundamental threats. is problematic since important ecological roles. To encourage informed conservation planning...
The identification of sea turtle behaviours is a prerequisite to predicting the activities and time-budget these animals in their natural habitat over long term. However, this hampered by lack reliable methods that enable detection monitoring certain key such as feeding. This study proposes combined approach automatically identifies different free-ranging turtles through use animal-borne multi-sensor recorders (accelerometer, gyroscope time-depth recorder), validated video-recorder data. We...
Understanding the spatial ecology of sea turtles is essential to ensure their long-term conservation by preservation environment. The distribution and environmental preferences for egg-laying green turtle ( Chelonia mydas ) were studied on Grande Saziley beach in Mayotte (north Mozambique Channel). Green nesting activity was geolocated during night patrols depth specific nests measured two field campaigns 2021 2022. Various original parameters related vegetation morphology extracted a GIS...
This study tested the potential influence of meteorological parameters (temperature, humidity, wind direction, thermal convection) on different migration characteristics (namely flight speed, altitude and direction daily distance) in 16 black storks ( Ciconia nigra ). The birds were tracked by satellite during their entire autumnal spring migration, from 1998 to 2006. Our data reveal that 27-day-long between Europe Africa (mean distance 4100 km), periods maximum activity corresponded energy,...
Abstract Satellite remote-sensing and wildlife tracking allow researchers to record rapidly increasing volumes of information on the spatial ecology marine megafauna in context global change. This field investigation is thereby entering realm big data science: Information technology allows design completely new frameworks for acquiring, storing, sharing, analysing, visualizing, publicizing data. review aims at framing importance conservation megafauna, through intimate knowledge these...
Abstract Although it is commonly assumed that female sea turtles always return to the beach they hatched, pathways use during years preceding their first reproduction and natal origins are most often unknown, as case for juvenile green found in Martinique waters Caribbean. Given oceanic circulation of Guiana current flowing toward presence important nesting sites this species Suriname French Guiana, we may assume a large proportion originating from Suriname–French beaches. To confirm...
Accelerometers are becoming ever more important sensors in animal-attached technology, providing data that allow determination of body posture and movement thereby helping elucidate behaviour animals difficult to observe.We sought validate the identification sea turtle behaviours from accelerometer signals by deploying tags on carapace a juvenile loggerhead (Caretta caretta), an adult hawksbill (Eretmochelys imbricata) green (Chelonia mydas) at Aquarium La Rochelle. We recorded tri-axial...
Marine turtles have long been considered to be silent, but few investigations performed confirm such muteness. However, recent studies on the aerial and underwater hearing abilities of marine shown they an ability perceive sounds, suggesting potential existence acoustic communication among them. In present study, audio-video recorders were deployed 11 free-ranging juvenile green sea Chelonia mydas at Grande Anse d’Arlet in Martinique. The recordings revealed that produced 10 different sound...
In response to seasonality and spatial segregation of resources, sea turtles undertake long journeys between their nesting sites foraging grounds. While satellite tracking has made it possible outline migration routes, we still have little knowledge how they select grounds adapt dynamic environmental conditions. Here, analyzed the trajectories diving behavior 19 adult green (Chelonia mydas) during post-nesting from French Guiana Suriname off coast Brazil. First Passage Time analysis was used...

Based on novel hierarchical system logistic regression classifiers relatively small set features extracted from the filtered signals, proposed outperformed previous work DaLiAc (Daily Life Activity) mHealth datasets.

Abstract Yalimapo beach, near the Maroni River estuary in French Guiana, is an important turtle nesting site. The interaction of massive mud banks migrating alongshore from distant Amazon with discharge generates strong beach morpho-sedimentary changes. eventual degradation marine habitats resulting these changes represents a threat to offspring, and consequently, population.
