Marine turtle threats in Uruguayan waters: insights from 12 years of stranding data
It is demonstrated that Uruguayan coastal waters likely serve as a foraging or development area for at least three endangered marine turtle species in temperate waters.
Ontogenetic dietary changes of green turtles (Chelonia mydas) in the temperate southwestern Atlantic
The overall evidence indicates that green turtles inhabiting the coastal waters off Uruguay exhibit a rapid, but not abrupt, dietary shift after recruiting to neritic habitats and are best described as omnivores than as pure herbivores, with a relevant role of gelatinous macrozooplankton in their diets.
Incidental catch of marine turtles by Spanish bottom trawlers in the western Mediterranean
A questionnaire-based survey of fishermen was conducted in the Valencia region (eastern Spain) to assess the levels of marine turtle bycatch. Interviews covered 41.3% of the bottom trawling fleet in…
Differential impact of marine debris ingestion during ontogenetic dietary shift of green turtles in Uruguayan waters.
Ecological regime shift drives declining growth rates of sea turtles throughout the West Atlantic
This study assembled growth rate data from throughout the West Atlantic for green turtles, Chelonia mydas, which are long-lived, highly migratory, primarily herbivorous mega-consumers that may migrate over hundreds to thousands of kilometers.
Management and research on plastic debris in Uruguayan Aquatic Systems: update and perspectives
Synthetic plastics have become an indispensable component of modern life, and the amount of plastics disposal has increased dramatically as a result. With human population increasing, it is expected…
Kelps’ Long-Distance Dispersal: Role of Ecological/Oceanographic Processes and Implications to Marine Forest Conservation
Long-distance dispersal is one of the main drivers structuring the distribution of marine biodiversity. This study reports the first occurrence of Macrocystis pyrifera and Durvillaea antarctica rafts…
Combined use of mitochondrial and nuclear genetic markers further reveal immature marine turtle hybrids along the South Western Atlantic
Considering the high frequency of hybrids in the SWA, continuous monitoring should be performed to assess the fitness, genetic integrity, and extent of changes in the gene pools of involved populations.

The first occurrences of the brown seaweed Myriogloea major Asensi and the green seaweed Gayralia oxysperma are reported along the Uruguayan coast, which could represent respectively a northward and southward range extension for M. major and G. oxys perma in the Southwestern Atlantic.
