| limited mhc polymorphism in whales. | little is known about disease and genetic variation in aquatic mammalian species such as whales. in this paper human hla class i and class ii probes were used to study major histocompatibility complex (mhc) genes from two species of whale: fin (balaenoptera physalus) and sei (b. borealis). stronger signals were obtained on whale than on equivalent concentrations of mouse dna. evidence was obtained for several drb-related genes, a dna genes, one dqa gene, and multiple class i genes in whales. int ... | 1989 | 2562799 |
| propulsion of a fin whale (balaenoptera physalus): why the fin whale is a fast swimmer. | measurements of an immature fin whale (balaenoptera physalus), which died as a result of entrapment in fishing gear near frenchmans cove, newfoundland (47 degrees 9' n, 55 degrees 25' w), were made to obtain estimates of volume and surface area of the animal. detailed measurements of the flukes, both planform and sections, were also obtained. a strip theory was developed to calculate the hydrodynamic performance of the whale's flukes as an oscillating propeller. this method is based on linear, t ... | 1989 | 2570423 |
| energy absorption from ocean waves: a free ride for cetaceans. | flukes of cetaceans are capable of absorbing energy from ocean waves for propulsion. the extent of this energy absorption is demonstrated by considering the flukes of an immature fin whale, balaenoptera physalus. in a fully developed seaway corresponding to a wind speed of 20 knots (around beaufort force 5) and at a low swimming speed, of 2.5 m s-1, this whale was able to absorb up to 25% of its required propulsive power in head seas and 33% of propulsive power in following seas. consequences of ... | 1990 | 1974063 |
| the complete amino acid sequence of prolactin from the sea turtle (chelonia mydas). | the complete amino acid sequence of prolactin (prl) from a reptile, the sea turtle (chelonia mydas), was determined for the first time. sequence analysis was performed on fragments obtained from cleavage of intact and performic acid-oxidized hormone with lysyl endopeptidase, staphylococcus aureus protease, and o-iodosobenzoic acid employing manual edman degradation. the sea turtle prl consists of 198 amino acid residues with three disulfide linkages formed between residues 4-11, 58-173, and 190- ... | 1990 | 2289679 |
| analysis of the c4 genes in baleen whales using a human cdna probe. | we have used a human c4 cdna probe to investigate the complement component c4 gene in four members of the family balaenopteridae: fin whale (balaenoptera physalus), sei whale (b. borealis), minke whale (b. acutorostrata), and bryde's whale (b. edeni). restriction mapping of genomic dna from the first three species suggests the presence of only one locus in these species, and also shows that the c4 genes in the three species are very similar. we have used 14 restriction endonucleases to investiga ... | 1990 | 1975799 |
| involucrin-like proteins in non-primates. | a monoclonal and two polyclonal antibodies to human involucrin were used to look for involucrin epitopes in other species. all antibodies react strongly with the same proteins of monkey, and both polyclonal antibodies react with specific proteins of cow and dog. one of the polyclonal antibodies also reacts with proteins of sheep, guinea pig, rat, and finback whale. the immunoreactive proteins from cow and dog could be purified using a procedure developed for human involucrin. the reaction with t ... | 1990 | 1688904 |

| molecular identification of hybrids between the two largest whale species, the blue whale (balaenoptera musculus) and the fin whale (b. physalus). | three anomalous balaenopterid whales, one pregnant female and two sterile males, were investigated by applying molecular approaches in order to establish their identity. the analysis showed that the whales were species hybrids between the blue and the fin whales. the female and one of the males had a blue whale mother and a fin whale father. the other male had a fin whale mother and a blue whale father. the difference between the mitochondrial cytochrome b gene of the two species suggests that t ... | 1991 | 1687408 |
| crassicaudosis: a parasitic disease threatening the health and population recovery of large baleen whales. | this communication briefly reviews knowledge of the systemic disease caused by crassicauda boopis in blue whales (balaenoptera musculus), fin whales (b. physalus) and humpback whales (megaptera novaeangliae). infections with this giant nematode characteristically incite a chronic inflammatory reaction of the blood vessels which drain the kidneys. in this critical location, the parasite-induced lesion can cause complete vascular occlusion and kidney failure. whale calves and juveniles typically s ... | 1992 | 1305859 |
| mysticete (baleen whale) relationships based upon the sequence of the common cetacean dna satellite. | the genomes of all extant cetaceans are characterized by the presence of the so-called common cetacean dna satellite. in the mysticetes (whalebone whales) the repeat length of the satellite is 1,760 bp. in the odontocetes (toothed whales), other than the family delphinidae, the repeat length is usually approximately 1,740 bp. the delphinidae are characterized by a repeat length of approximately 1,580 bp. it has been shown in odontocetes that the satellite evolves in concert and that differences ... | 1992 | 1435232 |
| the complete mitochondrial dna sequence of the harbor seal, phoca vitulina. | the nucleotide sequence of the mitochondrial dna (mtdna) of the harbor seal, phoca vitulina, was determined. the total length of the molecule was 16,826 bp. the organization of the coding regions of the molecule conforms with that of other mammals, but the control region is unusually long. a considerable portion of the control region is made up of short repeats with the motif gtacac particularly frequent. the two rrna genes and the 13 peptide-coding genes of the harbor seal, fin whale, cow, huma ... | 1992 | 1593642 |
| effects of amino acid substitutions outside an antigenic site on protein binding to monoclonal antibodies of predetermined specificity obtained by peptide immunization: demonstration with region 56-62 (antigenic site 2) of myoglobin. | this work was carried out in order to study the effects of substitutions outside antigenic site 2 of sperm whale myoglobin (spmb) on the reactivity of protein variants with antisite 2 monoclonal antibodies (mabs). a synthetic peptide corresponding to region 56-62 (site 2) of spmb was used as an immunogen in mice in its free form (i.e., without coupling to any carrier) to prepare a panel of mabs whose predetermined specificity is directed, by design, against this region. the binding of three of t ... | 1992 | 1280438 |
| effects of amino acid substitutions outside an antigenic site on protein binding to monoclonal antibodies of predetermined specificity obtained by peptide immunization: demonstration with region 15-22 (antigenic site 1) of myoglobin. | monoclonal antibodies (mabs) of predetermined specificity were prepared by immunizing with a free (i.e., not conjugated to any carrier) synthetic peptide representing region 15-22 (site 1) of sperm whale myoglobin (spmb). the cross-reactions of mb variants with three mabs were studied in order to determine whether such interactions are influenced by substitutions outside the site. finback whale mb, which has no substitutions within region 15-22, showed lower cross-reactivity and relative binding ... | 1992 | 1280437 |
| sex hormone concentrations in blood serum from the north atlantic fin whale (balaenoptera physalus). | blood serum concentrations of testosterone and progesterone were measured in postmortem samples taken at sea from 814 fin whales (balaenoptera physalus) caught during the summers (june-september) of 1981-1989. the ages of 781 of these animals were also assessed. the testosterone concentrations in samples from 352 males averaged 2 nmol/l; 41 samples had concentrations of 0.1 nmol/l or lower and 34 of these came from whales aged between 2 and 14 years and showed a gaussian type of age distribution ... | 1992 | 1402548 |
| 20-hz pulses and other vocalizations of fin whales, balaenoptera physalus, in the gulf of california, mexico. | low-frequency vocalizations were recorded from fin whales, balaenoptera physalus, in the gulf of california, mexico, during three cruises. in march 1985, recorded 20-hz pulses were in sequences of regular 9-s interpulse intervals. in august 1987, nearly all were in sequences of doublets with alternating 5- and 18-s interpulse intervals. no 20-hz pulse sequences of any kind were detected in february 1987. the typical pulse modulated from 42 to 20 hz and its median duration was 0.7 s (1985 data). ... | 1992 | 1474220 |
| evidence that fin whales respond to the geomagnetic field during migration. | we challenge the hypothesis that fin whales use a magnetic sense to guide migration by testing for associations between geophysical parameters and the positions where fin whales were observed over the continental shelf off the northeastern united states. monte carlo simulations estimated the probability that the distribution of fin whale sighting was random with respect to bottom depth, bottom slope and the intensity and gradient of the geomagnetic field. the simulations demonstrated no overall ... | 1992 | 1431731 |
| nucleotide sequence of the d-loop region of the sperm whale (physeter macrocephalus) mitochondrial genome. | we have amplified, by the polymerase chain reaction, and have sequenced the d-loop region of the mitochondrial dna from the sperm whale (physeter macrocephalus). the sperm whale d-loop was aligned with d-loop sequences from four other cetaceans (commerson's dolphin, orca, fin whale, and minke whale) and an out-group (cow). this alignment showed the sperm whale sequence to be larger than that of other cetaceans. in addition, some sequence blocks were highly conserved among all six species, sugges ... | 1993 | 8487632 |
| comparison between the complete mtdna sequences of the blue and the fin whale, two species that can hybridize in nature. | the sequence of the mitochondrial dna (mtdna) molecule of the blue whale (balaenoptera musculus) was determined. the molecule is 16,402 bp long and its organization conforms with that of other eutherian mammals. the molecule was compared with the mtdna of the congeneric fin whale (b. physalus). it was recently documented that the two species can hybridize and that male offspring are infertile whereas female offspring may be fertile. the present comparison made it possible to determine the degree ... | 1993 | 8308901 |
| epidermal lipid in several cetacean species: ultrastructural observations. | the ultrastructure of the skin of four cetacean species, bottlenose dolphin (tursiops truncatus) long-finned pilot whale (globicephala melaena), humpback whale (megaptera novaeangliae), and fin whale (balaenoptera physalus) was investigated with particular reference to epidermal lipid. it has already been established that massive lipid reservoirs exist in whales, that the biochemical structures of cetacean lipids are unique, and that unusual intracellular lipid droplets appear in the epidermis. ... | 1993 | 8250278 |
| comparative chromosome painting discloses homologous segments in distantly related mammals. | comparative chromosome painting, termed zoo-fish, using dna libraries from flow sorted human chromosomes 1, 16, 17 and x, and mouse chromosome 11 discloses the presence of syntenic groups in distantly related mammalian orders ranging from primates (homo sapiens), rodents (mus musculus), even-toed ungulates (muntiacus muntjak vaginalis and muntiacus reevesi) and whales (balaenoptera physalus). these mammalian orders have evolved separately for 55-80 million years (myr). we conclude that zoo-fish ... | 1994 | 8054973 |
| reproductive transfer and variation of body load of organochlorine pollutants with age in fin whales (balaenoptera physalus). | the body load of tddt (p,p'ddt + o,p'ddt + p,p'dde + p,p'tde) and polychlorinated biphenyls (sum of congeners) was estimated for 169 fin whales to study age and sex-related variation and to calculate the quantity of these compounds transferred to offspring through reproduction. blubber was the body compartment containing the greatest quantities of organochlorines, but its relative contribution to total load was lower than in other cetaceans because in fin whales muscle and bone are also signific ... | 1994 | 7811111 |
| arterial mechanics in the fin whale suggest a unique hemodynamic design. | an analysis of the dimensions of the aortic tree and the mechanical properties of arterial wall tissues in the fin whale (balaenoptera physalus) is presented. the aortic arch is greatly expanded, having an internal radius at an estimated mean blood pressure (13 kpa) that is 2.5 times greater than that of the descending thoracic aorta. at this pressure, the elastic modulus of the arch wall (0.4 mpa) is 30 times less than that of the descending aorta (12 mpa). consequently, even though some capaci ... | 1994 | 8092327 |
| blue and fin whales observed on a seafloor array in the northeast pacific. | calling blue and fin whales have been tracked using relative travel times and amplitudes from both direct and multipath arrivals to a seafloor array of seismometers. calls of three fin whales swimming in the same general direction, but several kilometers apart, are believed to represent communication between the whales because of signature differences in call character, an alternating call pattern, and coordination of call and respiration times. whale call tracks, call patterns, call character, ... | 1995 | 7642810 |
| systematics of cetaceans using restriction site mapping of mitochondrial dna. | phylogenetic analysis of 14 cetacean species, including members from two baleen whale families and three toothed whale families, was undertaken using restriction site mapping of mitochondrial dna and using cladistic and distance measures to infer phylogenies. the amount of between-taxa sequence divergence inferred from the data was lower than expected from the standard interpretation of the fossil record, but more consistent with some recent estimates of sequence divergence in cetacean mitochond ... | 1995 | 7620632 |
| post mortem investigations on cetaceans found stranded on the coasts of italy between 1990 and 1993. | detailed pathological and virological examinations were carried out on 25 cetaceans found stranded between 1990 and 1993 on the coasts of six italian regions (latium, tuscany, apulia, abruzzo, veneto and sicily). there were 16 striped dolphins (stenella coeruleoalba), three bottlenosed dolphins (tursiops truncatus), three risso's dolphins (grampus griseus), one rough-toothed dolphin (steno bredanensis), one fin whale pup (balaenoptera physalus), and one minke whale (balaenoptera acutorostrata). ... | 1995 | 7631479 |
| arterial windkessels in marine mammals. | in marine mammals, the aortic arch is enlarged relative to the descending aorta to varying degrees in different species. the ratio of maximal diameter of the arch to that of the thoracic aorta is about 2.3 in the harbour seal (phoca vitulina), 3.6 in the weddell seal (leptonychotes weddelli) and 3.2 in the fin whale (balaenoptera physalus), compared with only 1.4 in the dog. this anatomical specialisation probably provides increased volume capacitance in the arterial circulation as an adaptation ... | 1995 | 8571227 |
| organochlorine levels in subcutaneous blubber biopsies of fin whales (balaenoptera physalus) and striped dolphins (stenella coeruleoalba) from the mediterranean sea. | polychlorinated biphenyls (pcbs) and ddt compounds were determined in subcutaneous blubber of fin whales (balaenoptera physalus) and striped dolphins (stenella coeruleoalba) from the mediterranean sea. from 1990 to 1993, 68 fin whale and 89 dolphin blubber biopsies were analysed. the whales were sampled while passing through the ligurian sea, whereas the dolphins were collected in different areas of the mediterranean: the ligurian, tyrrhenian and ionian seas. total pcbs and ddts were 5.5-7.1 ppm ... | 1996 | 15091448 |
| the mitochondrial dna molecule of sumatran orangutan and a molecular proposal for two (bornean and sumatran) species of orangutan. | the complete mitochondrial dna (mtdna) molecule of sumatran orangutan, plus the complete mitochondrial control region of another sumatran specimen and the control regions and five protein-coding genes of two specimens of bornean orangutan were sequenced and compared with a previously reported complete mtdna of bornean orangutan. the two orangutans are presently separated at the subspecies level. comparison with five different species pairs-namely, harbor seal/grey seal, horse/donkey, fin whale/b ... | 1996 | 8875856 |
| the complete mitochondrial dna (mtdna) of the donkey and mtdna comparisons among four closely related mammalian species-pairs. | the nucleotide sequence of the complete mitochondrial genome of the donkey, equus asinus, was determined. the length of the molecule is 16,670 bp. the length, however, is not absolute due to pronounced heteroplasmy caused by variable numbers of two types of repetitive motifs in the control region. the sequence of the repeats is (a) 5'-cacaccca and (b) 5'-tgcgcgca, respectively. the order of (a) and (b) can be expressed as {n[2(a)+(b)]+m(a)}. in 32 different clones analyzed the number of n and m ... | 1996 | 8875857 |
| [viruses of whales and dolphins]. | dna- and rna-genome viruses of whales and dolphins belong to families poxviridae, herpesviridae, adenoviridae, orthomyxoviridae, paramyxoviridae, togaviridae, picornaviridae. virological, serological and pathomorphological signs of infection have been registered in odontoceti (bottle-nosed dolphin, atlantic white-sided dolphin, striped dolphin, harbona porpoise, white-beaked dolphin, common dolphin, sperm whale, pilot whale, white whale) and musticeti (sei whale, fin whale, gray whale, and bowhe ... | 1996 | 9044706 |
| some acoustical properties of the otic bones of a fin whale. | the otic bones in this report are the tympanic bulla, the periotic, and the three ossicles (malleus, incus, and stapes) of an adult fin whale (balaenoptera physalus). the purpose was to determine if the periotic was denser than the other otic bones. it was found in one male adult fin whale that the density of all the otic bones is approximately the same, 2.50 kg/m3 with a maximum of 2.58. the lowest density was observed in the stapes (2.36). the sonic velocity seems to vary as the density but th ... | 1996 | 8730088 |
| identification of sex in cetaceans by multiplexing with three zfx and zfy specific primers. | we sequenced 540 nucleotides of the last exon in the zfy/zfx gene in two males and two females for eight cetacean species; four odontocetes (toothed whales) and four mysticetes (baleen whales). based upon the obtained nucleotide sequences, we designed two sets of oligonucleotide primers for specific amplification of the zfx and the zfy sequence in odontocetes and mysticetes, respectively. each primer set consisted of three oligonucleotides; one forward-orientated primer, which anneals to the zfy ... | 1996 | 8673273 |
| the mechanical properties of fin whale arteries are explained by novel connective tissue designs. | the aortic arch and the descending aorta in the fin whale (balaenoptera physalus) are structurally and mechanically very different from comparable vessels in other mammals. although the external diameter of the whale's descending thoracic aorta (approximately 12 cm) is similar to that predicted by scaling relationships for terrestrial mammals, the wall thickness:diameter ratio in the whale (0.015) is much smaller than the characteristic value for other mammals (0.05). in addition, the elastic mo ... | 1996 | 8788091 |
| heavy metals in two populations of north atlantic fin whales (balaenoptera physalus). | concentrations of cadmium, copper and zinc have been analyzed in muscle, liver and kidney tissues of fin whales (balaenoptera physalus) from two locations in the north atlantic, iceland and spain. the concentrations of zinc in the muscle and that of cadmium in the liver and the kidney were significantly higher in fin whales from iceland. other differences between whales from the two areas concern the dynamics of cadmium in the organism. these findings support the hypothesis that fin whales from ... | 1996 | 15091422 |
| the use of non destructive biomarkers in the study of marine mammals. | marine mammals have been subject to heavy anthropogenic pressure by direct killing and chemical pollution all over the world. most studies of contamination and biomarker responses in marine mammals have been conducted using animals killed by hunting out of a total of 12 cetacean species studied, 45 of the specimens were obtained by sacrificing the animal; out of a total of eight pinniped species studied, 40 of the specimens were obtained by killing. the development of a series of non destructive ... | 1997 | 23899212 |

| relationship between organochlorine contaminants and mixed function oxidase activity in skin biopsy specimens of mediterranean fin whales (balaenoptera physalus). | the relationship between organochlorine contaminants (pcbs and ddts) and mixed function oxidase, benzo(a)pyrene monooxigenase activity (bpmo), was investigated in skin biopsy specimens from fin whales (balaenoptera physalus) of the mediterranean sea. skin biopsy material, sampled by a non invasive technique, is suitable for a wide range of chemical and biomarker analysis. in this study pcbs and ddts were evaluated in subcutaneous blubber and mfo activity in epidermis. an interesting correlation ... | 1998 | 9753763 |
| population genetic structure of north atlantic, mediterranean sea and sea of cortez fin whales, balaenoptera physalus (linnaeus 1758): analysis of mitochondrial and nuclear loci. | samples were collected from 407 fin whales, balaenoptera physalus, at four north atlantic and one mediterranean sea summer feeding area as well as the sea of cortez in the pacific ocean. for each sample, the sex, the sequence of the first 288 nucleotides of the mitochondrial (mt) control region and the genotype at six microsatellite loci were determined. a significant degree of divergence was detected at all nuclear and mt loci between north atlantic/mediterranean sea and the sea of cortez. howe ... | 1998 | 9633102 |
| multiple levels of single-strand slippage at cetacean tri- and tetranucleotide repeat microsatellite loci. | between three and six tri- and tetranucleotide repeat microsatellite loci were analyzed in 3720 samples collected from four different species of baleen whales. ten of the 18 species/locus combinations had imperfect allele arrays, i.e., some alleles differed in length by other than simple integer multiples of the basic repeat length. the estimate of the average number of alleles and heterozygosity was higher at loci with imperfect allele arrays relative to those with perfect allele arrays. nucleo ... | 1999 | 9872967 |
| evidence of brucella infection in marine mammals in the north atlantic ocean. | between 1983 and 1996 a total of 1386 samples of serum were taken from four species of seal and three species of whale in the waters west of iceland, the area of pack-ice north-west of jan mayen, the northern coast of norway and the kola peninsula, the waters west of svalbard, and the barents sea; they were tested for the presence of anti-brucella antibodies with an indirect elisa (protein g conjugate). the positive sera were re-tested with classical brucellosis serological tests, such as the se ... | 1999 | 10378290 |
| complete nucleotide sequence of pig (sus scrofa) mitochondrial genome and dating evolutionary divergence within artiodactyla. | the complete nucleotide sequence of the pig (sus scrofa) mitochondrial genome, containing 16613bp, is presented in this report. the genome is not a specific length because of the presence of the variable numbers of tandem repeats, 5'-cgtgcgtaca in the displacement loop (d-loop). genes responsible for 12s and 16s rrnas, 22 trnas, and 13 protein-coding regions are found. the genome carries very few intergenic nucleotides with several instances of overlap between protein-coding or trna genes, excep ... | 1999 | 10433971 |
