Cigüeñas y gaviotas transportan cientos de kilos de plásticos desde los vertederos a los humedales de Andalucía.

Viene derivado de la mala gestion de los vertederos, con consecuencias negativas sobre los humedales y por tanto sobre el propio ciclo del agua.

The pivotal temperature of sea turtles, which is key in temperature-dependent sex determination, is mainly between 29–30 °C.

Among the outreach activities we have carried out, we presented a workshop on our study of loggerhead turtle nesting in the Alboran Sea and its accidental capture during the X Festival del Mar.

In the Alboran Sea, due to the low temperatures it can reach, many juvenile loggerhead turtles wash ashore because they go into hypothermia.
If you find one, call 112.

Two very special species of sea turtles. One of the main feeding areas for the loggerhead turtle is on the Spanish Levante coast, which is now developing as a nesting area.

Sightings of the green sea turtle have always been exceptional in our waters, but it is believed that this species is also expanding its range.

Plastic pollution is devastating our oceans - more than 8 million tons enter the seas every year, harming wildlife.

To better understand the movements and behavior of sea turtles, we prepare satellite trackers that record their routes once released.

With the participation of the fishing sector, we can assess the magnitude of these interactions and propose practical solutions that benefit both fishermen and marine conservation.

These surveys collect information on:

- Frequency and type of interactions
- Damage to gear and associated costs
- Bycatch
- Known or applied mitigation measures

In the surveys, we aim to understand interactions between fishing gear and dolphins and sea turtles.

We have already started surveys of trawl, purse seine, and gillnet fleets at the ports of Málaga, Granada, and Almería, as part of the ALMA Project.

The critical sublethal temperature for sea turtle embryos is around 34 °C. At this threshold, they survive but may suffer effects on their development and viability.

Data show that sea turtles tolerate more extreme temperatures than crocodiles and alligators, highlighting Caretta caretta for its broad thermal tolerance and adaptations to different nesting environments.

Good news!!

The green turtle has been rescued from the brink of extinction.

Thanks to decades of global conservation efforts, green turtle populations are finally returning.
