| genotoxic assessment of small mammals at an illegal dumpsite at the aomori-iwate prefectural boundary. | in 2003, we examined the chromosomes of grass voles at an illegal dumpsite at the aomori-lwate prefectural boundary. in subsequent years, from 2003-2006, we surveyed the chromosomes of four species of small mammals, namely, the japanese grass vole (microtus montebelli), the large japanese field mouse (apodemus speciosus), the small japanese field mouse (a. argenteus), and the greater japanese shrew mole (urotrichus talpoides). each annual survey revealed, both on a yearly basis and during the en ... | 2009 | 19341331 |
| chromosomal aberrations in japanese grass voles in and around an illegal dumpsite at the aomori-iwate prefectural boundary. | bone marrow chromosomes of thirty specimens of the japanese grass vole, microtus montebelli (2n=30), which had been caught on and near an illegal dumpsite at the aomori-iwate prefectural boundary, were analyzed and compared with those of fifteen grass voles from non-polluted areas as part of an effort to assess genotoxic influences on grass voles in the dumpsite area. fifty metaphases per specimen were examined with particular attention to numerical and structural aberrations. two specimens from ... | 2008 | 18393568 |
