Dear colleagues, We are pleased toshare our new article published in Marine Mammal Science. The Franciscana (Pontoporiablainvillei) in the Northern Limit of the FMA II: Strandings and HabitatUse in Ilha Grande Bay. https://doi.org/10.1111/mms.70184 Alexandre F. Azevedo; Rafael R.

Bisi; José Lailson-Brito Jr.   Abstract  The presence of the franciscana (Pontoporia blainvillei)at the northern limit of the FMA II was investigated using a range of methods,including monitoring of strandings, boat surveys, and passive acousticmonitoring (PAM). Franciscana strandings were recorded within thedistributional gap between Macaé (22°55′ S) and Ilha Grande (23°09′ S),suggesting that the northern boundary of the FMA II may extend as far as Jaconé(22°56′ S; 42°38′ W). Furthermore,habitat use in Ilha Grande Bay was in­vestigated through a combination of boatsurveys and PAM efforts. Our findings support the idea that the species useIlha Grande Bay year-round, both day and night, and this bay might be theprimary habitat of P. blainvillei in the FMA II section of the Rio deJaneiro coast. In Ilha Grande Bay, the franciscana is widely distributed overan area of more than 300 km2, along isobaths be­tween 8 and 30 m. There weremultiple detection events at the same PAM station during the day, indicatingthat the species was present at different times of day at the same location.Average group size was 7.7 (±6.7). While P. blainvillei occupies a largearea of the bay, further investigation is needed into its use of shallowerwaters and the deeper, central portion of the bay, as well as the presence ofareas with higher individual densities.   If you have any inquiries, please feel free to reach out at:azevedo.alex@uerj.br or alexandre.maqua@gmail.com Kind regards, Rafael Carvalho --  BiólogoDoutor em Ecologia e Evolução-PPGEE/UERJ Laboratório de Mamíferos Aquáticos e Bioindicadores "Izabel Gurgel" - MAQUA Faculdade de Oceanografia Universidade do Estado do Rio de Janeiro - UERJ  tel.: (21) 2334-0065 / 2334-0795 cel.: (21) 99802-3536http://lattes.cnpq.br/6546679825444246
