Abstract Acquisition of data on animal movement when developing management strategies is a common challenge in species conservation, especially when dealing with a critically endangered species as the hawksbill turtle Eretmochelys imbricata. To reach the objective of the 2008 national action plan for Martinique Island (French West Indies), the present paper examines horizontal and vertical movements in juveniles (n = 3) and adults life stages (11 females and 2 males) of 16 hawksbill turtles… Expand
Spatial ecology of hawksbill sea turtles (Eretmochelys imbricata) in foraging habitats of the Gulf of California, Mexico
Abstract Understanding movement patterns and habitat preferences of endangered species during their most vulnerable life stages is a key step to developing effective conservation strategies thatExpand
High fidelity of sea turtles to their foraging grounds revealed by satellite tracking and capture-mark-recapture: New insights for the establishment of key marine conservation areas
Abstract Movement ecology studies are essential to protect highly mobile threatened species such as the green turtle (Chelonia mydas), classified as an endangered species by the IUCN. In 2019, theExpand
Survival and breeding interval of an endangered marine vertebrate, the leatherback turtle Dermochelys coriacea, in French Guiana
Analysis of data from the long-term monitoring program of leatherbacks in French Guiana provides a sound structure for broader and richer analyses to extract biological information from marked individuals and offers an invaluable source of demographic information on leatherbacks, a species for which only a small segment of the population is accessible to intermittent sampling. Expand
Sources and movements of marine turtles in the Gulf of Venezuela: Regional and local assessments
Marine turtles are challenging species to protect because they occur over large geographic scales. Tagging individual turtles at nesting beaches and foraging areas, and the resulting mark-recaptureExpand
Detecting, counting and following the giants of the sea: a review of monitoring methods for aquatic megavertebrates in the Caribbean
Abstract The Caribbean is a mega-diverse and bio-geographically important region that consists of the Caribbean Sea, its islands, and surrounding coastlines. Among the billions of aquatic speciesExpand
Epizoic diatoms on sea turtles and their relationship to host species, behaviour and biogeography: a morphological approach
Sea turtles harbour epizoic diatoms of which several taxa are considered exclusivelyEpizoic and possible ‘commensals’ and possible 'commensal’ species are considered. Expand
Behavioural inference from signal processing using animal-borne multi-sensor loggers: a novel solution to extend the knowledge of sea turtle ecology
It is shown here that the combination of supervised learning algorithms and multi-signal analysis tools can provide accurate inferences of the behaviours expressed, including feeding and scratching behaviours that are of crucial ecological interest for sea turtles. Expand


Spatial ecology of critically endangered hawksbill turtles Eretmochelys imbricata: implications for management and conservation
The results underscore the importance of strengthening protected area management, man- grove estuary protection and hawksbill research and conservation in the eastern Pacific. Expand
Patterns of dispersal of hawksbill turtles from the Cuban shelf inform scale of conservation and management
Abstract Conserving and managing populations of marine vertebrates can be complex when they occupy the waters of multiple nations, crossing heterogeneous legal and management landscapes. HawksbillExpand
Inter-annual variability in the home range of breeding turtles: implications for current and future conservation management.
Abstract We assessed home range size for breeding loggerhead turtles ( Caretta caretta ) near the limit of the species range at the Greek island of Zakynthos in the Mediterranean. Thirteen adultExpand
Ecology of Hawksbill Turtles, Eretmochelys imbricata, on a Western Caribbean Foraging Ground
Abstract We present results of an inwater research program focusing on basic ecology of juvenile hawksbill turtles (Eretmochelys imbricata) in the Cayman Islands. We made 206 captures of 135Expand
Inter-nesting behavioural adjustments of green turtles to an estuarine habitat in French Guiana
This study aimed to investigate how gravid green turtles Chelonia mydas nesting in Suriname and French Guiana have adapted to the unusual habitat of the Maroni River estuary, which has highly turbid and low salinity waters and a priori lacks seagrass. Expand
Home range of immature hawksbill turtles (Eretmochelys imbricata (Linnaeus)) at two Caribbean islands
It is concluded that immature hawksbill turtles maintain a limited home range area and appear resident at the feeding grounds of Mona and Monito Islands for periods of at least several years. Expand
Foraging niche segregation between juvenile and adult hawksbill turtles (Eretmochelys imbricata) at Príncipe island, West Africa
Data on the trophic and foraging ecology of both juvenile and adult hawksbill turtles found in the shallow waters of Principe are presented, using stable isotope analyses of carbon and nitrogen to assess any isotopic niche segregation between these two life-stages and suggest part of the adults may be originating from isotopically distinct areas.

Sex-specific migration patterns of hawksbill turtles breeding at Mona Island, Puerto Rico
Detailed post-breeding movement data is presented for hawksbill turtles tracked by satellite telemetry from Mona Island, Puerto Rico, and significant differences observed in migratory range between males and females are interpreted in an evolutionary context of food abundance pre- dictability.

Diving behavior and movements of juvenile hawksbill turtles Eretmochelys imbricata on a Caribbean coral reef
Habit use of hawksbill turtles on a Caribbean coral reef was elucidated by quantifying diel depth utilization and movements in relation to the boundaries of marine protected areas and found variable dive capacity may reduce intraspecific competition and provide resistance to degradation in shallow habitats.

Identification of key marine areas for conservation based on satellite tracking of post-nesting migrating green turtles (Chelonia mydas)
The green turtle (Chelonia mydas) is classified as an endangered species on the IUCN Red List since 1986. This species is especially threatened in South America due to bycatch by fisheries along theExpand
