Abstract
While polyandry in sea turtles is indicated through multiple-paternity analyses of offspring, confirmed observations of the same female mating with multiple males are extremely challenging to obtain. To contribute to this discussion, we analysed a long-term photo-identification database (>20 years) of adult male and female loggerhead sea turtles frequenting the breeding area of Zakynthos, Greece, Mediterranean. A total of 38 records of mating individuals within and across seasons were assimilated via field surveys and citizen science records between 2003 and 2020. For one female, we recorded it mating with two different males within a 5.5-h interval on the same day in 2015. This observation constitutes the first direct evidence of polyandry in sea turtles, in addition to highlighting the potential for photo-identification to contribute information on less well-known aspects of sea turtle biology, such as validating outputs of genetic studies.
期刊介绍：
Marine Ecology publishes original contributions on the structure and dynamics of marine benthic and pelagic ecosystems, communities and populations, and on the critical links between ecology and the evolution of marine organisms.
The journal prioritizes contributions elucidating fundamental aspects of species interaction and adaptation to the environment through integration of information from various organizational levels (molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, palaeontology and modelling) as viewed from an ecological perspective. The journal also focuses on population genetic processes, evolution of life histories, morphological traits and behaviour, historical ecology and biogeography, macro-ecology and seascape ecology, palaeo-ecological reconstruction, and ecological changes due to introduction of new biota, human pressure or environmental change.
Most applied marine science, including fisheries biology, aquaculture, natural-products chemistry, toxicology, and local pollution studies lie outside the scope of the journal. Papers should address ecological questions that would be of interest to a worldwide readership of ecologists; papers of mostly local interest, including descriptions of flora and fauna, taxonomic descriptions, and range extensions will not be considered.
