Dear MARMAMers, We are pleased to announce that the following paper has been published online: Morgana Vighi, A. Borrell, A. Aguilar Bone as a surrogate tissue to monitor metals in baleen whales ABSTRACT Metals are massively deposited in the marine environment through direct emissions or atmospheric dry and wet depositions, a process since long enhanced by human activities. Metal contamination in the marine organisms has been increasingly investigated, but most research focuses on few tissues, elements and species considered indicative. Baleen whales have been scarcely studied in this respect. Here we contribute to the fragmented knowledge on this field examining the concentrations of zinc, copper, lead, titanium and strontium in the bone of fin whales (Balaenoptera physalus) from NW Spain and W Iceland. Bone was selected because it is a tissue commonly available in archival historic collections, and it is therefore useful to examine long-term trends in metal pollution. We tested differences between populations and we investigated age- and sex-related accumulation trends, as well as the occurrence of placental transfer. Sr concentrations and Pb accumulation rates with age were significantly higher in individuals from NW Spain than in those from W Iceland. Placental transfer occurred, at different levels, for all metals: as a result fetuses showed significantly higher Cu, Pb and Zn concentrations than adults. After birth, only Zn and Pb concentrations significantly increased with age. Through this study we contributed to fill some gaps in the knowledge regarding metal contamination in marine mammals, and we concluded that bone can be a suitable surrogate tissue to monitor a number of trace elements, provided that dissimilarities in tissue-specific deposition are taken into account when comparing concentrations from different tissues. free access to the article will be available until February 09, 2017, from the following link: *http://www.sciencedirect.com/science/article/pii/S0045653516317489 <http://www.sciencedirect.com/science/article/pii/S0045653516317489>* For any questions do not hesitate to contact me at: morgana.vighi@gmail.com A merry Christmas and a great beginning of 2017 to you all, Best regards, Morgana Vighi -- Morgana Vighi, PhD Departament de Biologia Evolutiva, Ecologia i Ciències Ambientals University of Barcelona Av.
