Citizen sea science platform Observadores del Mar, with the scientific lead by the Doñana Biological Station – CSIC, launches the project “Sea turtles”. Anyone can send information and images of turtle sighting to help know their distribution and reproduction, as well as, study their threats and improve their conservation

A group of researchers, with the participation of the Doñana Biological Station – CSIC, has carried out a study to know if the predation rate of loggerhead turtle nests changes across thermal habitats and if sea turtles have the ability to choose nest sites with less predatory prevalence.

A loggerhead turtle nesting was detected on the urban beach of Los Boliches in Fuengirola (Málaga, Spain). The hatchlings have been included in a head-starting program in the Center for the Management of Marine Environment Resources of Andalusia (CEGMA) and part of them have been released in Fuengirola. It is planned to release the rest of them in September.
The Western Mediterranean Basin is becoming a more frequent nesting area. Marine turtles are likely to return to the beach or area...

Climate change plays a key role in the development and survival of oviparous ectotherms such as sea turtles. Higher environmental temperatures are expected to lead to increased production of female hatchlings and potential feminization of many populations, as well as reduced hatching success and hatchling fitness. This study shows how different sand temperatures affect sea turtle embryo mortality, hatchling phenotype, and hatchling predation during their crawl to the sea. It was conducted in...

The colonisation of new suitable habitats is crucial for species survival at evolutionary scale under changing environmental conditions. However, colonisation potential may be limited by philopatry that facilitates exploiting successful habitats across generations. This study examined the mechanisms of long distance dispersal of the philopatric loggerhead sea turtle (Caretta caretta) by analysing 40 sporadic nesting events in the western Mediterranean. The analysis of a fragment of the...
