Otters are known to communicate using scent marks from a mixture of anal gland secretions (�jellies�) and feces (�spraints�) which are deposited at terrestrial latrines in their home ranges (Rostain, R. R. et al. Anim. Behav. 2004 , 68, 703-71). Volatile organic compounds have been identified via solid phase microextraction (SPME)/GC-MS analysis of anal gland/feces from the Eurasian otter (Lutra lutra) and are thought to signal age, sex, and reproductive status (Kean, E. F. et al. Chem. Senses 2011 , 36, 555-564). As part of a larger project on the effects of climate change on North American river otter (Lontra Canadensis) sociality using tracking and genetic sampling for inference on association patterns in Alaska, we have collected latrine-deposited anal gland secretions/feces samples. Headspace analysis using automated solid phase dynamic extraction (SPDE)/GC-MS has identified a large number of volatile compounds. These are being analyzed for evidence of sexual and individual differences.
