March 2024
The Guiana dolphin (Sotalia guianensis) is categorized as vulnerable in the Brazilian list of endangered animals, and its populations suffer from several anthropological threats. In this study, we analyzed the presence of macro, meso, and microplastics (MPs) in Guiana dolphins (n = 12) in Brazil Southeastern coast by analysing their gastrointestinal tract. The MP extractions were carried out with HO (35 %) to remove organic matter.

- The genus Stenella includes five species found in all oceans, but there’s limited genetic diversity data, especially in the Southwest Atlantic.
- A study analyzing three mitochondrial genes in 80 Stenella specimens found moderate to high genetic diversity and identified distinct haplogroups, with some species showing clustering similarities.
- The research indicates ongoing gene flow among species, which complicates taxonomy and understanding of their evolutionary relationships.
