The Earliest Record of the Active Season of Mertensiella djanaschvilii (Tartarashvili and Bakradze 1989) (Urodela: Salamandridae)
摘要
Abstract
The larvae and adults of Mertensiella djanaschvilii were observed in a stream water at an altitude of 1919 m located on the Ağaçbaşı plateau, Köprübaşı district of Trabzon province. A field study was conducted on April 20, 2024, when the snow had just started to melt. It is the earliest record showing the transition to the active season for M. djanaschvilii, which has a narrow thermal tolerance. The time of transition for activation will vary in different ecological conditions.
