Article Synopsis
- Researchers studied the population structure of Hynobius retardatus salamanders in Hokkaido, Japan, using mitochondrial DNA from 105 individuals.
- They identified 20 haplotypes grouped into three distinct clusters, with Group 1 found in most areas, while Groups 2 and 3 were limited to specific regions (Erimo and southern Hokkaido, respectively).
- The distribution of these groups did not overlap, indicating a clear hierarchical population structure influenced by both genetic barriers and past climate and landscape changes.
Certain plastic morphological responses of animals induced across a range of environmental conditions may be adapted for effective locomotor performance. Larvae of the salamander, Hynobius retardatus, occasionally swim upward to the surface to breathe air because aquatic respiration alone is insufficient to meet their increasing respiratory requirements for growth. We hypothesized that H.
