Postbreeding Male (Hasumi)

Postbreeding Male

A postbreeding adult (seeming male) of the salamander Hynobius kimurae, hidden under a log (cover object) on the ground surface near the right bank of a main stream in a wetland in Hokujo, Hakuba-mura, Nagano Prefecture, Japan, surveyed on 4 May 2003 (see another population). In this wetland, several branched streams (water temperatures of approximately 12 C) are collected into the main stream (water temperature of 11 C).

All captures but one (see above) were as follows:
H. kimurae:
(1) 9 unsexed adults under logs on the ground surface,
(2) 2 unsexed adults under decaying leaves on the ground surface,
(3) 3 unsexed adults under logs and stones on a saturated slope due to water exuded from a wetland (they seemed to be just back to land after breeding activity ceased); and
Hyla japonica:
(1) 1 juvenile under a log on the ground surface.

We released these individuals to sites where they were captured, immediately after taking some photographs.
