| upregulation of hypoxia-inducible factor (hif)-1α and hif-2α mrna levels in dragonet callionymus valenciennei exposed to environmental hypoxia in tokyo bay. | there is an urgent need to develop reliable biomarkers of environmental hypoxia exposure in marine organisms in order to assess the ecological impacts of the marked increase in coastal hypoxia worldwide. full-length hypoxia-inducible factor hif-1α and hif-2α cdnas were cloned and characterized from dragonet callionymus valenciennei, a representative epibenthic teleost inhabiting hypoxic areas in tokyo bay, to evaluate the potential utility of their transcript levels as biomarkers of environmenta ... | 2012 | 22683105 |
| changes in growth and reproductive traits of dragonet callionymus valenciennei in tokyo bay, concurrent with decrease in stock size. | we examined changes in the growth and reproductive traits of dragonet callionymus valenciennei concurrent with decrease in stock size in tokyo bay. stock size in mid 2000s decreased to 14% of that recorded in early 1990s. the minimum standard length at which dragonet attain gonadal maturation was smaller in 2000s (4.8 cm) compared to that in 1990s (6.0 cm). in addition, timing of the onset of the first spawning became earlier in 2000s (starting from spring) than that in 1990s (from summer). we a ... | 2014 | 23998795 |
