cold and heat tolerance of drosophilid flies with reference to their latitudinal distributions. | the relation between thermal tolerance and latitudinal distribution was studied with 30 drosophilid species collected from the cool-temperate region (sapporo), the warm-temperate region (tokyo and kyoto) and the subtropical region (iriomote island) in japan. in addition, intraspecific variation was examined for five species collected from two localities. the subtropical strains of scaptodrosophila coracina, drosophila bizonata and d. daruma were less tolerant to cold than their temperate strains ... | 2004 | 15221433 |
