| supplemental diagnosis of kudoa funduli (myxozoa) parasitizing fundulus heteroclitus (cyprinodontidae) from coastal northeastern north america. | the diagnosis of kudoa funduli (hahn, 1915) meglitsch, 1948 (myxozoa), is supplemented through study of new material collected from fundulus heteroclitus (cyprinodontidae) in coastal waters of nova scotia, canada, and connecticut. plasmodia normally develop intracellularly in striated muscle of the flank and head, eventually rupturing and releasing spores. spores disperse along adjacent epimysium, sometimes as far as the skin surface. some plasmodia develop extracellularly within the bony caviti ... | 2004 | 15270088 |
| isolation of viral haemorrhagic septicaemia virus from mummichog, stickleback, striped bass and brown trout in eastern canada. | viral haemorrhagic septicaemia virus (vhsv) was isolated from mortalities occurring in populations of mummichog, fundulus heteroclitus, stickleback, gasterosteus aculeatus aculeatus, brown trout, salmo trutta, and striped bass, morone saxatilis, in new brunswick and nova scotia, canada. the isolated viral strains produced a cytopathic effect on the epithelioma papillosum cyprini cell line. serum neutralization indicated the virus was vhsv and sequencing identified the rhabdovirus isolates as the ... | 2007 | 17394523 |
| morphological and molecular taxonomy of a new species of fundulotrema and comments on gyrodactylus stephanus (monogenea: gyrodactylidae) from fundulus heteroclitus (actinopterygii: cyprinodontiformes) in nova scotia, canada. | fundulotrema porterensis n. sp. (monogenea: gyrodactylidae) is described from the mummichog, fundulus heteroclitus (l.; cyprinodontidae), inhabiting porters lake, nova scotia, canada. the new parasite species is characterized by having a ventral bar with small anterolateral processes and linguiform membrane, differentiating it from all other known species of fundulotrema. the morphological description of f. porterensis is supplemented with 1011 sequenced base pairs (bp) of ribosomal dna (rdna) s ... | 2009 | 20049991 |
| diversity and distribution of gynogenetic hybrids between fundulus diaphanus and fundulus heteroclitus in porter's lake (nova scotia) in relation to salinity. | unisexual hybrids between fundulus diaphanus and fundulus heteroclitus were found in low proportions at intermediate salinity in porter's lake, nova scotia. one clone accounted for 72% of the hybrids, with most other hybrids being different at a single microsatellite allele. this clone thrives over a wide range of salinities, suggesting a general-purpose genotype. | 2009 | 20738603 |
| up-regulation of hepatic abcc2, abcg2, cyp1a1 and gst in multixenobiotic-resistant killifish (fundulus heteroclitus) from the sydney tar ponds, nova scotia, canada. | cellular defence against accumulation of toxic xenobiotics includes metabolism by phase i and ii enzymes and export of toxicants and their metabolites via atp-binding cassette (abc) transporters. liver gene expression of representatives of these three protein groups was examined in a population of multixenobiotic-resistant killifish (fundulus heteroclitus) from the sydney tar ponds, nova scotia, canada. the tar ponds are heavily polluted with polycyclic aromatic hydrocarbons, polychlorinated bip ... | 2009 | 19443023 |
| asexual and sexual hybrids between fundulus diaphanus and f. heteroclitus in the canadian atlantic region. | levels and origins of clonal diversity in asexual hybrid animals are critical to understanding how they can coexist with their sexual progenitor species. in this study, asexual gynogenetic hybrids between fundulus diaphanus and fundulus heteroclitus known from two sites in nova scotia (canada) were characterized using discriminant morphological traits, eight microsatellite loci, and mitochondrial dna. fifteen clonal genotypes were uncovered, all bearing the same f. diaphanus maternal haplotye. e ... | 2007 | 17391270 |
