AmphibiaWeb - Hyla orientalis
AMPHIBIAWEB
Hyla orientalis Bedriaga, 1890
Eastern Tree Frog, Oriental Tree Frog
Subgenus: Hyla
family: Hylidae
subfamily: Hylinae
genus: Hyla
 
Taxonomic Notes: Removed from the synonymy of Hyla arborea by Stoeck et al 2008 Mol. Phyl. Evol. 49. based on their molecular phylogenetic analysis. A note on generic placement: Duellman et al. (Zootaxa 2016) treated two major clades as genera; AmphibiaWeb treats these two clades as subgenera (Hyla in the Old World; Dryophytes in the New World and East Asia), thus stabilizing traditional taxonomy.

The range of Hyla orientalis almost completely circumnavigates the Black Sea (and possibly does) throughout Turkey, northwest through Bulgaria and eastern Romania and north through Ukraine, Poland and as far as Lithuania; to the east, it ranges across the Caucasus Range to the Caspian Sea and northern Iran (Stoeck et al 2008).

Comments
This species was featured in news of the week October 10, 2022.

In 1986, the Chernobyl (or alternatively spelled ‘Chornobyl’) nuclear accident in northern Ukraine released unprecedented amounts of radioactive material into the environment. Within the Chernobyl Exclusion Zone, Burrac and Orizaola (2022) surveyed the Eastern Tree Frog (Hyla orientalis) and found increased melanism compared with frogs just outside the Exclusion Zone. It is known that the dark melanin-based pigments could protect fungi against ionizing radiation but a protective role in melanism for vertebrates remains debated because of potentially high physiological costs associated with melanism. Burrac and Orizaola found no physiological costs associated with the maintenance of dark skin coloration in terms of frog body condition or oxidative status. Furthermore no short-term changes in coloration were detected, indicating that high levels of ionizing radiation, likely at the time of the accident, may have been selected for darker coloration in Chernobyl tree frogs.
