Dear MARMAMers,   My co-authors and I are pleased toannounce the publication of a new paper about serum chemistry values of 107wild-caught Amazon river dolphins (Inia geoffrensis) published in MarineMammal Science DOI: 10.1111/mms.12765   Abstract: Blood values of wild cetaceanpopulation are a valuable tool to drive proper management of threatenedspecies. Reference intervals of 26 serum analytes were determined from 107apparently healthy Amazon river dolphins (Inia geoffrensis) wild‐caughtin the Mamirauá Sustainable Development Reserve (3°3′S, 64°51′W), centralAmazon, Brazil. No differences were detected between males and females orbetween pregnant and nonpregnant females. Calves had higher serum calcium thanjuveniles and adults, and alkaline phosphatase activity was higher in calvesand juveniles than adults as a result of bone growth. Adults showed highercreatinine levels than juveniles due to higher body mass, and higher urea thancalves. Positive correlation was found between body length and body weight withcreatinine, urea, and alanine aminotransferase activity; whereas calcium andalkaline phosphatase and creatine kinase (CK) activities negatively correlatedwith these body parameters. Cardiac rate and respiratory frequency appear tohave not correlated with any serum analyte, while stress level positivelycorrelated with CK. Storage of frozen samples for 60 days at −80°Csignificantly altered 10 of the 19 analytes after one freeze–thaw cycle.Important differences were detected among age classes, stress level, and samplestorage and should be taken into account before any clinical or physiologicalinterpretations.   The link to the abstract can be found at  https://onlinelibrary.wiley.com/doi/10.1111/mms.12765 and a pdf can be requested to danielamello@hotmail.com Thank you and kind regards,   Daniela Mello.  --  Daniela M.
