| prevalence of sarcocystis sp. in stranded atlantic white-sided dolphins (lagenorhynchus acutus). | in january 1998 and 1999, two mass strandings of dolphins occurred in wellfleet, massachusetts. the strandings were composed of 97 and 53 animals, respectively. tissues from 35 atlantic white-sided dolphins (lagenorhynchus acutus) from the 1998 stranding and 52 from the 1999 stranding were examined histologically. in the 1998 stranding, unidentified protozoal tissue cysts were seen in skeletal muscle from 11 of 28 (39%) dolphins. in addition, two dolphins had a protozoal tissue cyst in cardiac m ... | 2002 | 12038128 |
| mortality trends of stranded marine mammals on cape cod and southeastern massachusetts, usa, 2000 to 2006. | to understand the cause of death of 405 marine mammals stranded on cape cod and southeastern massachusetts between 2000 and 2006, a system for coding final diagnosis was developed and categorized as (1) disease, (2) human interaction, (3) mass-stranded with no significant findings, (4) single-stranded with no significant findings, (5) rock and/or sand ingestion, (6) predatory attack, (7) failure to thrive or dependent calf or pup, or (8) other. the cause of death for 91 animals could not be dete ... | 2010 | 20225675 |
| factors influencing persistent organic pollutant concentrations in the atlantic white-sided dolphin (lagenorhynchus acutus). | assessing the trends of persistent organic pollutants (pops) in cetaceans is difficult because of age and gender influences on accumulation. persistent organic pollutants bioaccumulate and are poorly metabolized; hence, concentrations may increase with age in males while females reduce their pop burden through parturition and lactation. age and gender effects on contaminant concentrations are species specific because of life history and reproductive strategies. these influences must be understoo ... | 2005 | 16110985 |
