| a common eurasian fish tapeworm, caryophyllaeides fennica (cestoda) in western north america: further evidence of 'amphi-pacific' vicariance in freshwater fish parasites. | the freshwater fish fauna of the palaearctic and nearctic regions shows similarities but also notable differences, resulting in diverse distributions of their parasites. relatively few parasite species occur in both regions and fewer still have been examined using molecular data. we report a rare example of 'amphi-pacific' distribution, involving the common palaearctic parasite, the caryophyllidean cestode caryophyllaeides fennica (schneider, 1902), in the chiselmouth acrocheilus alutaceus agass ... | 2017 | 28594283 |
