| occurrence of the ectoparasite isocyamus deltobranchium (amphipoda: cyamidae) on cetaceans from atlantic waters. | the cyamids collected from a true's beaked whale (mesoplodon mirus), a common dolphin (delphinus delphis), and a harbour porpoise (phocoena phocoena) stranded in galicia (nw spain) were identified as isocyamus deltobranchium, extending the range of this species to the atlantic ocean. the three cetacean species examined are new hosts for this parasite. the microscopic examination of female specimens reveals that certain important taxonomic characters can be present or absent depending on the matu ... | 2008 | 18576834 |
| using multipath reflections to obtain dive depths of beaked whales from a towed hydrophone array. | beaked whales are deep divers, emitting echolocation clicks while at depth. little is known about the dive behavior of most species; however, passive acoustic data collected with towed hydrophone arrays can provide depth information using multipath reflections of clicks coupled with a two-dimensional localization of the individual. data were collected during a shipboard survey in the western north atlantic ocean using a towed linear hydrophone array. beaked whale tracks were classified as either ... | 2017 | 28863608 |
| true's beaked whale (mesoplodon mirus) in macaronesia. | the true's beaked whale (mesoplodon mirus, true 1913) is a poorly known member of the ziphiidae family. its distribution in the northern hemisphere is thought to be restricted to the temperate or warm temperate waters of the north atlantic, while a few stranding records from the southern hemisphere suggest a wider and antitropical distribution, extending to waters from the atlantic coast of brazil to south africa, mozambique, australia and the tasman sea coast of new zealand. this paper (i) repo ... | 2017 | 28286714 |
| microplastic and macroplastic ingestion by a deep diving, oceanic cetacean: the true's beaked whale mesoplodon mirus. | when mammals strand, they present a unique opportunity to obtain insights into their ecology. in may 2013, three true's beaked whales (two adult females and a female calf) stranded on the north and west coasts of ireland and the contents of their stomachs and intestines were analysed for anthropogenic debris. a method for identifying microplastics ingested by larger marine organisms was developed. microplastics were identified throughout the digestive tract of the single whale that was examined ... | 2015 | 25667115 |
| spectral characterization of two bioaccumulated methoxylated polybrominated diphenyl ethers. | two methoxylated polybrominated diphenyl ethers (meo-pbdes) were isolated from a true's beaked whale (mesoplodon mirus) and identified by nmr (1h, 1h-1h and 1h-13c) and high resolution mass spectrometry as 2-(2',4'-dibromophenoxy)-3,5-dibromoanisole (6-meo-bde47) and 2-(2',4'-dibromophenoxy)-4,6-dibromoanisole (2'-meo-bde68). previously the structures of these bioaccumulated compounds have been determined by comparison of their mass spectra and gas chromatographic (gc) retention times with those ... | 2006 | 16005047 |
| two abundant bioaccumulated halogenated compounds are natural products. | methoxylated polybrominated diphenyl ethers (meo-pbdes) have been found bioaccumulated in the tissues of a variety of aquatic animals and at concentrations comparable to those of anthropogenic halogenated organic compounds, including polychlorinated biphenyls (pcbs). the origin of the meo-pbdes has been uncertain; circumstantial evidence supports a natural and/or an industrial source. by analyzing the natural abundance radiocarbon content of two meo-pbdes isolated from a true's beaked whale (mes ... | 2005 | 15705850 |
