Assessing sea turtle movements and connectivity among different areas is pivotal to understanding their biology and implementing efficient conservation actions. In the Adriatic Sea, one of the most important sea turtle foraging areas in the Mediterranean, a total of 311 capture–mark–recapture (CMR) records (mostly bycatch) from 294 loggerhead turtles (Caretta caretta) in the period 1984–2021 were analysed. A general fidelity pattern to Adriatic subareas was indicated by a significantly shorter CMR distance than the potential dispersal distance and by the significantly higher proportion of re-encounters in the same area of release than expected. No seasonal pattern was detected between subareas, and shorter re-encounter distances were observed in turtles released and re-encountered in the same season, suggesting different winter and summer residential areas. Results suggest that turtles frequenting the Adriatic can go anywhere in the Mediterranean basin and may exhibit a wandering behaviour regardless of their size. A substantial connectivity with nesting sites in Greece was observed, confirming with empirical evidence that this is the most important breeding area for turtles foraging in the Adriatic Sea. This study highlights the value of cooperation among different groups and shows a main behavioural pattern of fidelity to neritic foraging grounds. [ABSTRACT FROM AUTHOR]

Much is still to be learned about the spatial ecology of foraging marine turtles, especially for juveniles and adult males which have received comparatively little attention. Additionally, there is a paucity of ecological information on growth rates, size and age at maturity, and sex ratios at different life stages; data vital for successful population modelling. Here, we present results of a long-term (2002-2011) study on the movements, residency, growth and sex ratio of loggerhead turtles (Caretta caretta) in Amvrakikos Gulf (39°0'N21°0'E), Greece, using satellite telemetry (N = 8) and ongoing capture-mark-recapture (CMR; N = 300 individuals). Individuals encountered at sea ranged from large juvenile to adult (46.2-91.5 cm straight carapace length) and demonstrated growth rates within published norms (44 % of captures above 65 cm straight carapace length), compared to region-wide female-biased hatchling production, indicating sex-biased survival or possible behavioural drivers for likelihood of capture in the region. Satellite tracking confirmed that some turtles establish discrete, protracted periods of residency spanning more than 1 year, whilst others migrated away from the site. These findings are underlined by CMR results with individual capture histories spanning up to 7 years, and only 18 % of individuals being recaptured., Introduction Understanding the ecology of marine vertebrates is challenging as a result of the wide spatiotemporal scales over which their life cycles may take place (e.g. Block et al. 2005; [...]

The article reports that a Loggerhead Sea Turtle in Greece was observed to have a reproductive lifespan of 37 years, marking it as the longest recorded for the species. Topics include the longevity of Loggerhead Sea Turtles, methods for determining reproductive lifespan, and the role of tagging programs in tracking turtle lifespans.

The article explores the nesting behavior of a Loggerhead Sea Turtle (Caretta caretta) nicknamed "Stumpy," which was missing both hind limbs and flipper spades, shedding light on how turtles with such disabilities attempt to dig nests.

Information on caretta caretta from Caribbean including informations related to topics like its diet, the habitat in which it is found, and its physical traits is presented.

The article focuses on the leatherback sea turtle in the Gulf of Corinth, Greece. It mentions that Dermochelys coriacea is the largest of all living turtles and is the fourth-heaviest modern reptile behind three crocodilians. According to the International Union for Conservation of Nature that Dermochelys coriacea is classified as vulnerable worldwide.

The article presents a study which monitor nesting activities of loggerheads sea turtle in Zakynthos Island. The researchers from ARCHELON Association conducted daily beach surveys, tagging of female turtles and operation of nationwide Sea Turtle Stranding Network. Results showed that monk seals in Zakynthos prey on loggerheads during the nesting season. It concludes that declining marine species have forced monk seals to prey on turtles and suggests finding solutions to address the problem.

The article offers information on the satellite tracking of a green turtle after nesting in Latakia in North Africa. It states that the population of green turtle or Cholia mydas in the Mediterranean has been demonstrated to be relatively discrete in the wider Atlantic. As for the tracking of the turtle, the article states the it lasted for 95 days during which the turtle migrated southward and then eastward. It also mentions that the turtle settled in the Bay of As Sallum, West Egypt where it remained in neritic coastal waters for the final 26 days of transmission.

The article information on turtle specie Caretta caretta. It mentions that the predation rates are greater at early life stages and decline as turtles gain larger sizes. It also mentions that the current observation suggests that anglerfish in Greece are likely opportunistic consumers of juvenile C. caretta.
