| can sines: a family of trna-derived retroposons specific to the superfamily canoidea. | a repetitive element of approximately 200 bp was cloned from harbour seal (phoca vitulina concolour) genomic dna. the sequence of the element revealed putative rna polymerase iii control boxes, a poly a tail and direct terminal repeats characteristic of sines. sequence and secondary structural similarities suggest that the sine is derived from a trna, possibly trna-alanine. southern blot analysis indicated that the element is predominately dispersed in unique regions of the seal genome, but may ... | 1994 | 8052527 |
| structure and amount of genetic variation at minisatellite loci within the subspecies complex of phoca vitulina (the harbour seal). | the structure and amount of genetic variation within and between three subspecies of the harbour seal phoca vitulina was assessed by multilocus dna fingerprinting. bandsharing similarity indicates that the subspecies phoca vitulina richardsi (alaska, east pacific) is clearly separated from the other two subspecies, phoca vitulina concolor (sable island, west atlantic) and phoca vitulina vitulina (north sea, east atlantic). the subspecies also differ significantly in the estimated amount of heter ... | 1997 | 9172395 |
| ontogeny of the thermal limits in the harbor seal (phoca vitulina). | we measured metabolic rates (ml o2 h-1, converted to kcal d-1), deep body temperatures (degree c), and skin temperatures (degree c) and calculated whole-animal thermal conductances (ml o2 g-1 h-1 degree c-1) of five 3-yr-old harbor seals (phoca vitulina concolor) at air temperatures between -20 degrees and 35 degrees c. the mean thermal neutral zone of these seals extended from a lower critical temperature of -12.9 degrees +/- 1.6 degrees c (sd) to an upper critical temperature of 28.6 degrees + ... | 1997 | 9231380 |

| polychlorinated biphenyls and chlorinated pesticides in harbor seals (phoca vitulina concolor) from the northwestern atlantic coast. | concentrations of polychlorinated biphenyls (pcbs), dichlorodiphenyltrichloroethane (ddt) and its metabolites, chlordane-related compounds (chls), mirex, hexachlorocyclohexane isomers (hchs), dieldrin, and hexachlorobenzene (hcb) were determined in blubber of harbor seals (phoca vitulina concolor) from the northwestern atlantic coast. pcbs, ddts, and chls were the major persistent organochlorines in harbor seal blubber, while mirex, hchs, dieldrin, and hcb were minor contaminants. highest concen ... | 2005 | 15907943 |
| dipetalonema spirocauda infection in the atlantic harbor seal (phoca vitulina concolor). | the clinical and pathologic effects of the filarioid nematode dipetalonema spirocauda were studied in the harbor seal, phoca vitulina concolor. aberrant behavior of both adults and microfilariae resulted in previously unreported pulmonary, vascular and hepatic lesions. | 1976 | 16502692 |
| bioaccumulation of polybrominated diphenyl ethers in harbor seals from the northwest atlantic. | polybrominated diphenyl ethers (pbdes) were analyzed in blubber of harbor seals (phoca vitulina concolor) collected between 1991 and 2005 along the northwest atlantic. summation operatorpbde concentrations (mono- to hexa-bdes) detected in blubber samples (n=42) ranged from 80 to 25720 ng g(-1)lw, (overall mean 2403+/-5406 ng g(-1)lw). by age, mean summation operatorpbde concentrations were: 3645+/-7388, 2945+/-5995, 1385+/-1265, and 326+/-193 ng g(-1)lw in pups, yearlings, adult males, and adult ... | 2008 | 18950831 |
| specific accumulation of perfluorochemicals in harbor seals (phoca vitulina concolor) from the northwest atlantic. | concentrations of perfluorochemicals (pfcs) including perfluoroalkylsulfonates (pfsas), and perfluoroalkylcarboxylates (pfcas) were determined in liver of harbor seals (n=68) collected from the northwest atlantic between 2000 and 2007. of ten pfcs measured, perfluorooctane sulfonate (pfos) concentrations were the highest in liver (8-1388 ng/g, ww), followed by perfluoroundecanoic acid (pfunda) (<1-30.7 ng/g, ww). an unusual accumulation profile of long-chain (c7-c12) pfcas, and the predominance ... | 2009 | 19101009 |
| saxitoxin increases phocine distemper virus replication upon in-vitro infection in harbor seal immune cells. | several marine mammal epizootics have been closely linked to infectious diseases, as well as to the biotoxins produced by harmful algal blooms (habs). in two of three saxitoxin (stx) associated mortality events, dolphin morbillivirus (dmv) or phocine distemper virus (pdv) was isolated in affected individuals. while stx is notorious for its neurotoxicity, immunotoxic effects have also been described. this study investigated the role of stx in altering immune function, specifically t lymphocyte pr ... | 2016 | 28003064 |
| development of a one-step duplex rt-qpcr for the quantification of phocine distemper virus. | worldwide, stranded marine mammals and the network personnel who respond to marine mammal mortality have provided much of the information regarding marine morbillivirus infections. an assay to determine the amount of virus present in tissue samples would be useful to assist in routine surveying of animal health and for monitoring large-scale die-off events. false negatives from poor-quality samples prevent determination of the true extent of infection, while only small amounts of tissue samples ... | 2015 | 25647591 |
| esophageal squamous cell carcinoma in six harbor seals (phoca vitulina spp.). | six cases of esophageal squamous cell carcinoma were identified in six captive adult pacific (phoca vitulina richardsii; n = 2) and atlantic (phoca vitulina concolor; n = 4) harbor seals. these seals presented with intermittent dysphagia, regurgitation, inappetence, and abnormal posturing. common clinical pathology findings in these seals included azotemia, hyperproteinemia, hyperglobulinemia, and leukocytosis. gastrointestinal endoscopy commonly revealed an ulcerated mass near the gastroesophag ... | 2014 | 25314830 |
| methoxylated pbdes (meo-pbdes), hydroxylated pbdes (ho-pbdes) and hydroxylated pcbs (ho-pcbs) in the liver of harbor seals from the northwest atlantic. | metabolites of pcbs and pbdes are shown to influence the thyroid hormone homeostasis and therefore, could have an influence on the growth of newborn or young animals. we have investigated the occurrence of hydroxylated pcbs (ho-pcbs), hydroxylated pbdes (ho-pbdes), and methoxylated pbdes (meo-pbdes) in the liver (48 pups; 6 adults) and blubber (4 pups; 1 adult) of harbor seals (phoca vitulina concolor) from the northwest atlantic. the sum of ho-pcbs in the liver ranged from 90 to 22,450 pg/g wet ... | 2014 | 24982026 |
