Dugong Dugong dugon Lacépède, 1799, a globally threatened marine mammal that occurs in the coastal waters of the Indian and Pacific Ocean, is traded in small numbers throughout their range. We surveyed 128 shops selling wildlife in seven (June 2013) and eight (July 2014) towns on the island of Bali, one of Indonesia's most popular tourist destinations. Dugongs are protected under Indonesian law and CITES Appendix I Iisting precludes international trade. Despite this dugong parts were observed in trade in Denpasar, Mengwi and Sanur where 14 traders were interviewed. We recorded over 130 dugong parts, including raw bones and teeth but also many carved items and some derivatives, with no noticeable difference between years. The most common items were cigarette pipes carved from, predominantly, dugong ribs, and decorative carvings from bone and teeth. The total value of the items observed was $1500–3000. The trade was open and qualitatively similar to trade in parts of non-protected species. Information from traders suggests that dugongs are caught throughout Indonesia, and are both targeted specifically and caught accidentally. It is imperative for the management of dugongs to take the illegal trade in dugong parts into account and for the authorities to curb the trade by taking appropriate action in line with Indonesia's legislation. Greater awareness of the plight of the dugong, including the impediments to their conservation posed by the illegal trade in body parts, by the residents of and visitors to Bali, may aid in pressuring the authorities to take these steps.

Despite a long-documented history of severe harmful algal blooms (HABs) in New England coastal waters, corresponding HAB-associated marine mammal mortality events in this region are far less frequent or severe relative to other regions where HABs are common. This long-term survey of the HAB toxins saxitoxin (STX) and domoic acid (DA) demonstrates significant and widespread exposure of these toxins in New England marine mammals, across multiple geographic, temporal and taxonomic groups. Overall, 19% of the 458 animals tested positive for one or more toxins, with 15% and 7% testing positive for STX and DA, respectively. 74% of the 23 different species analyzed demonstrated evidence of toxin exposure. STX was most prevalent in Maine coastal waters, most frequently detected in common dolphins (Delphinus delphis), and most often detected during July and October. DA was most prevalent in animals sampled in offshore locations and in bycaught animals, and most frequently detected in mysticetes, with humpback whales (Megaptera novaeangliae) testing positive at the highest rates. Feces and urine appeared to be the sample matrices most useful for determining the presence of toxins in an exposed animal, with feces samples having the highest concentrations of STX or DA. No relationship was found between the bloom season of toxin-producing phytoplankton and toxin detection rates, however STX was more likely to be present in July and October. No relationship between marine mammal dietary preference and frequency of toxin detection was observed. These findings are an important part of a framework for assessing future marine mammal morbidity and mortality events, as well as monitoring ecosystem health using marine mammals as sentinel organisms for predicting coastal ocean changes.
