 Dear MARMAM community,

My coauthors and I are pleased to announce our new paper:
Li W-T, Chou L-S, Chiou H-Y, Chen I-H and Yang W-C (2021) Analyzing 13
Years of Cetacean Strandings: Multiple Stressors to Cetaceans in Taiwanese
Waters and Their Implications for Conservation and Future Research. *Front.
Mar. Sci.* 8:606722. doi: 10.3389/fmars.2021.606722

ABSTRACT:
This study summarizes the postmortem investigations of 73 cetaceans
stranded on the coast of Taiwan between 2001 and 2013, including 51
Delphinidae, 17 Kogiidae, 3 Ziphiidae, 1 Physeteridae, and 1
Balaenopteridae. Of these, eight (11%) were categorized into direct
human-related strandings, including fisheries interaction (bycatch), vessel
collision and other anthropogenic-related pathology. Gastrointestinal
foreign bodies were found in eight individuals (11%). Most of the bacteria
isolated from stranded dolphins were zoonotic pathogens including
extended-spectrum β-lactamases *Escherichia coli*, which indicates waste
pollution from land. Severe parasite infestation was found in 36 of the
cases (49%), which suggests that the immune function could be compromised.
Thirty-eight cases (52%) were diagnosed with myocardial patchy fibrosis or
dilated cardiomyopathy. The evidence shown here indicates that cetaceans
around Taiwanese waters may suffer from multiple stressors. This study
provides baseline data for the health assessment of cetacean populations in
Taiwan, which may ultimately provide recommendations for future cetacean
conservation and research throughout the western Pacific.
