Interaction Between Age and Individual Heterogeneity Shapes Breeding Probability in a Long‐Lived Marine Ectotherm

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Using a 52‐year dataset on captive green turtles, our study reveals that individual quality and age are the primary drivers of reproductive patterns. We found that high‐quality turtles bred more consistently throughout their lives and that females maintained a high reproductive value into old age despite evidence of physical aging.

Interspecific Associations of the Rare and Endangered Stingray (Styracura schmardae) in Caribbean Sandy‐Bottom Habitats

Ecology and Evolution, Volume 15, Issue 11, November 2025.
We document novel interspecific associations of the endangered Atlantic chupare stingray (Styracura schmardae) in Caribbean sandy‐bottom habitats. Observations include nuclear–follower interactions with needlefish (Strongylura marina) and hitchhiking by sharksuckers (Echeneis naucrates), revealed through direct in situ records and citizen science data ...

A case study of sea turtle hybridization in the north-western Caribbean verified by mitochondrial and multilocus nuclear sequences

Frontiers in Marine Science
IntroductionThe family Cheloniidae includes seven species of marine turtles, separated by tens of millions of years from their common ancestor. Despite this, there have been remarkable cases of hybridization between different species within this lineage.

Habitat Use and Foraging Ecology of Three Sea Turtle Species Nesting in Northwest Costa Rica

Marine Ecology, Volume 46, Issue 6, November/December 2025.
ABSTRACT Sea turtle species, even when sharing nesting beaches, exhibit distinct at‐sea movements and foraging behavior. At Playa Cabuyal, a sea turtle nesting beach in northwest Costa Rica, we utilized satellite telemetry to reveal the post‐nesting movement of green turtles (Chelonia mydas, n = 9) alongside carbon and nitrogen stable isotope analysis ...

First field observation of the predation by Jaguar (Panthera onca) on Olive Ridley sea turtle (Lepidochelys olivacea) at Nancite Beach, Santa Rosa National Park, Costa Rica

Mammalogy Notes, 2016
Jaguars have been recorded preying on adult female sea turtles on their nesting beaches in Costa Rica, Guyana, Mexico and Suriname (Fretey 1977, Autar 1994, Cuevas et al. 2014, Guildera et al. 2015).

Sustainable Scenarios in Tourism Based on the Observation of Sea Turtles Can Be in Risk When Social Drivers Change: A Socio‐Ecological Model

Natural Resource Modeling, Volume 38, Issue 4, November 2025.
ABSTRACT Nature tourism based on the observation of sea turtles is a socioeconomic activity that promotes the conservation of endangered species. However, tourism can affect the nesting sites, drastically affecting the ecosystem function. In this study, we propose a socio‐ecological model to describe the interplay between tourists and a turtle ...

Habitat fidelity in hawksbill sea turtles

Ecology, Volume 106, Issue 10, October 2025.
Abstract Climate change is altering habitat suitability and driving shifts in species distributions. To understand potential responses by mobile animals, it is essential to assess levels of plasticity in habitat use, ranging from transience to long‐term fidelity.

Long‐Term Incubation Duration Decline Indicates Climate‐Change Driven Feminization of Three Sea Turtle Species in Florida, USA

Global Change Biology, Volume 31, Issue 10, October 2025.
We analysed more than 110,000 sea turtle nests from three species across Florida to track climate‐driven changes in incubation duration, a simple proxy for hatchling sex. Our results reveal widespread shortening of incubation periods and thus increasing feminisation, but also identify geographic and seasonal refuges where more males are produced.
