Journal ArticleDOI
First Determination of UV Filters in Marine Mammals. Octocrylene Levels in Franciscana Dolphins
Pablo Gago-Ferrero,Mariana B. Alonso,Mariana B. Alonso,Carolina P. Bertozzi,Juliana Marigo,Lupércio A. Barbosa,Marta Jussara Cremer,Eduardo R. Secchi,Alexandre F. Azevedo,José Lailson-Brito,João Paulo Machado Torres,Olaf Malm,Ethel Eljarrat,M. Silvia Díaz-Cruz,Damià Barceló,Damià Barceló +15 more
TL;DR: This is the first study to investigate the presence of sunscreen agents in tissue liver of Franciscana dolphin, a species under special measures for conservation, and constitute the first data reported on the occurrence of UV filters in marine mammals worldwide.
Journal ArticleDOI
Pyrethroids: A new threat to marine mammals?
Mariana B. Alonso,Maria Luisa Feo,Cayo Corcellas,Lara G. Vidal,Lara G. Vidal,Carolina P. Bertozzi,Juliana Marigo,Eduardo R. Secchi,Manuela Bassoi,Alexandre F. Azevedo,Paulo R. Dorneles,Paulo R. Dorneles,João Paulo Machado Torres,José Lailson-Brito,Olaf Malm,Ethel Eljarrat,Damià Barceló +16 more
TL;DR: For the first time, a study shows mother-to-calf transfer of pyrethroids by both gestational and lactation pathways in dolphins, despite the assumption that these insecticides are converted to non-toxic metabolites by hydrolysis in mammals.
Journal ArticleDOI
Toxic heritage: Maternal transfer of pyrethroid insecticides and sunscreen agents in dolphins from Brazil.
Mariana B. Alonso,Mariana B. Alonso,Mariana B. Alonso,Maria Luisa Feo,Cayo Corcellas,Pablo Gago-Ferrero,Carolina P. Bertozzi,Juliana Marigo,Leonardo Flach,Ana Carolina Oliveira de Meirelles,Vítor Carvalho,Alexandre F. Azevedo,João Paulo Machado Torres,José Lailson-Brito,Olaf Malm,M. Silvia Díaz-Cruz,Ethel Eljarrat,Damià Barceló +17 more
TL;DR: The high PYR and UVF concentrations found in fetuses demonstrate these compounds are efficiently transferred through placenta, the first to report maternal transfer of pyrethroids and UV filters in marine mammals.
Journal ArticleDOI
Natural and anthropogenically-produced brominated compounds in endemic dolphins from Western South Atlantic: another risk to a vulnerable species.
Mariana B. Alonso,Mariana B. Alonso,Ethel Eljarrat,Marina Gorga,Eduardo R. Secchi,Manuela Bassoi,Lupércio A. Barbosa,Carolina P. Bertozzi,Juliana Marigo,Marta Jussara Cremer,Camila Domit,Alexandre F. Azevedo,Paulo R. Dorneles,Paulo R. Dorneles,João Paulo Machado Torres,José Lailson-Brito,Olaf Malm,Damià Barceló +17 more
TL;DR: Franciscana dolphins from the tropical Brazilian shore presented the highest MeO-PBDE concentrations ever reported for coastal cetaceans (up to 14 μg/g lw) and the present investigation constituted the first record of occurrence of six of them in marine mammal livers.
Journal ArticleDOI
Population Structure of the Endangered Franciscana Dolphin (Pontoporia blainvillei): Reassessing Management Units
Haydée A. Cunha,Bruna V. Medeiros,Lupércio A. Barbosa,Marta Jussara Cremer,Juliana Marigo,José Lailson-Brito,Alexandre F. Azevedo,Antonio M. Solé-Cava +7 more
TL;DR: A deep evolutionary break was observed between franciscanas from the northern and southern portions of the species distribution, indicating that they must be managed as two Evolutionarily Significant Units (ESU) and additional FMAs should be recognised to accommodate the genetic differentiation found in each ESU.
