| molecular insights into the colonization and chromosomal diversification of madeiran house mice. | the colonization history of madeiran house mice was investigated by analysing the complete mitochondrial (mt) d-loop sequences of 156 mice from the island of madeira and mainland portugal, extending on previous studies. the numbers of mtdna haplotypes from madeira and mainland portugal were substantially increased (17 and 14 new haplotypes respectively), and phylogenetic analysis confirmed the previously reported link between the madeiran archipelago and northern europe. sequence analysis reveal ... | 2009 | 19754514 |
| molecular studies on the colonization of the madeiran archipelago by house mice. | to study the colonization history of the house mouse (mus musculus domesticus) on the madeiran archipelago, complete mitochondrial d-loop sequences were obtained for 44 individuals from madeira, porto santo and ilhas desertas. altogether, 19 d-loop haplotypes were identified which formed part of a single clade in a phylogeny incorporating haplotypes from elsewhere in the range of m. m. domesticus, indicating that the madeiras were colonized from a single source. similarities between the sequence ... | 2001 | 11555245 |
| origin of the chromosomal radiation of madeiran house mice: a microsatellite analysis of metacentric chromosomes. | chromosome races of mus musculus domesticus are characterised by particular sets of metacentric chromosomes formed by robertsonian fusions and whole-arm reciprocal translocations. the atlantic island of madeira is inhabited by six chromosome races of house mice with 6-9 pairs of metacentric chromosomes. three of these races are characterised by the metacentric 3.8 also found elsewhere in the distribution of m. m. domesticus, including denmark and spain. we investigated the possibility that metac ... | 2013 | 23232832 |
| of mice and the 'age of discovery': the complex history of colonization of the azorean archipelago by the house mouse (mus musculus) as revealed by mitochondrial dna variation. | humans have introduced many species onto remote oceanic islands. the house mouse (mus musculus) is a human commensal and has consequently been transported to oceanic islands around the globe as an accidental stowaway. the history of these introductions can tell us not only about the mice themselves but also about the people that transported them. following a phylogeographic approach, we used mitochondrial d-loop sequence variation (within an 849- to 864-bp fragment) to study house mouse coloniza ... | 2015 | 25394749 |
| successful eradication of the european rabbit (oryctolagus cuniculus) and house mouse (mus musculus) from the island of selvagem grande (macaronesian archipelago), in the eastern atlantic. | the portuguese island of selvagem grande (great salvage) in macaronesia is an important seabird breeding station in the eastern atlantic. significant populations of cory's shearwater calonectris diomedea (scopoli, 1769), bulwer's petrel bulweria bulweria (jardine & selby, 1828) and little shearwater puffinus assimilis baroli (bonaparte, 1857) are present, and white-faced storm-petrel pelagodroma marina (latham, 1790) and madeiran storm-petrel oceanodroma castro (harcourt, 1851) populations are o ... | 2010 | 21392324 |
| fertility assessment in hybrids between monobrachially homologous rb races of the house mouse from the island of madeira: implications for modes of chromosomal evolution. | the speciation model of divergence by monobrachially homologous fusions (that is, with one arm in common) benefits from a wide conceptual acceptance, because heterozygotes between populations carrying such fusions suffer from high levels of meiotic dysfunction. the same meiotic configurations can also be generated by wart (whole-arm reciprocal translocation), rearrangements that are known to occur in mammals. estimating the disadvantage of heterozygotes carrying monobrachially homologous fusions ... | 2011 | 20531448 |
| patterns of genic diversity and structure in a species undergoing rapid chromosomal radiation: an allozyme analysis of house mice from the madeira archipelago. | the chromosomal radiation of the house mouse in the island of madeira most likely involved a human-mediated colonization event followed by within-island geographical isolation and recurrent episodes of genetic drift. the genetic signature of such processes was assessed by an allozyme analysis of the chromosomal races from madeira. no trace of a decrease in diversity was observed suggesting the possibility of large founder or bottleneck sizes, multiple introductions and/or a high post-colonizatio ... | 2007 | 17611494 |
| chromosomal phylogeny of robertsonian races of the house mouse on the island of madeira: testing between alternative mutational processes. | the ancestral karyotype of the house mouse (mus musculus) consists of 40 acrocentric chromosomes, but numerous races exist within the domesticus subspecies characterized by different metacentric chromosomes formed by the joining at the centromere of two acrocentrics. an exemplary case is present on the island of madeira where six highly divergent chromosomal races have accumulated different combinations of 20 metacentrics in 500-1000 years. chromosomal cladistic phylogenies were performed to tes ... | 2005 | 16303058 |
| radiocarbon evidence for the presence of mice on madeira island (north atlantic) one millennium ago. | owing to the catastrophic extinction events that occurred following the holocene arrival of alien species, extant oceanic island biotas are a mixture of recently incorporated alien fauna and remnants of the original fauna. knowledge of the late quaternary pristine island faunas and a reliable chronology of the earliest presence of alien species on each archipelago are critical in understanding the magnitude and tempo of quaternary island extinctions. until now, two successive waves of human arri ... | 2014 | 24523273 |
| detection of antibodies against anaplasma phagocytophilum in algerian mice (mus spretus), portugal. | the recent detection of anaplasma phagocytophilum in portugal stimulated further research on the agent's enzootic cycle, which usually involves rodents. thus a total 322 rodents belonging to five species, including 30 apodemus sylvaticus (wood mouse), 65 mus musculus (house mouse), 194 m. spretus (algerian mouse), 5 rattus norvegicus (brown rat) and 28 r. rattus (black rat), were studied by indirect immunofluorescent assay (ifa) and/or polymerase chain reaction (pcr) for a. phagocytophilum expos ... | 2009 | 18973448 |
