“…Metamorphosis starts about six weeks after the eggs have been laid, and hibernation lasts from October to May [12]. Sexual maturity is reached at the age of two years for males and three years for females, and maximum longevity is six years in males and seven years in females [53]. Frogs from high altitudes tend to be smaller than frogs from low altitudes [54].…”

“…Females can lay 1048 eggs and may spawn twice a year [13]. Pelophylax fukienensis was initially considered a subspecies or synonym of P. plancyi [13]; however, the validity of the species was confirmed based on molecular data from mainland and island populations [53,93]. Elevation was the variable with the highest contribution for P. fukienensis, with a contribution of 60% (Table 1), matching the distribution of the species, as it is present at comparatively high elevations.…”

Understanding species from an ecological and phylogenetic perspective facilitates an understanding of their conservation status in relation to the changing world. The frog genus Pelophylax is among the largest in terms of amphibian biomass in the Palearctic, but species have not been thoroughly studied at the Asian continental scale. The phylogeographic relationship, behavioural ecology, and ecological requirements within the genus need clarification, despite generally good local coverage. Here, for the first time, we conducted a literature review focused on phylogeography and behavioural ecology, supported by ecological niche modelling of twelve Asian Pelophylax lineages. Finally, we compiled the known threats for each of the lineages. We first determined the presence of twelve species and species-candidate lineages. In terms of behavioural ecology, the main difference among lineages is the time to metamorphosis and the time to reach sexual maturity. The ecological models highlighted a match between the known presence of each clade and their suitable habitat and highlighted the Syr Darya drainage on the eastern shore of the Caspian Sea for the non-described Pelophylax “Syr Darya lineage”. Finally, we highlighted the greatest variation among lineages in terms of threats, as some lineages are threatened by numerous factors, whereas others are expanding.
