Diurnal periodicity of abundance (total, male and female) and behavior (resting, feeding and croaking) of the frogs Euphlyctis cyanophlyctis, E. hexadactylus and Hoplobatrachus tigerinus inhabiting in ponds of the Western Ghats at different altitudes (high, mid and foothill) have been investigated during three seasons (monsoon, post-monsoon and summer). Irrespective of seasons, the air and water temperatures were significantly lower during night than day in all locations (p < 0.001) and the humidity was significantly higher in high-altitude (p < 0.05) than other locations. Total abundance was significantly high only during night in mid-altitude inhabiting frog E. hexadactylus (p < 0.05). The resting behavior was significantly lower during night than day in all frogs, while it was opposite for croaking behavior. The feeding behavior was significantly higher during day than night in E. cyanophlyctis (p < 0.05). Total abundance was significantly correlated with abundance of females. Three hourly observations up to 24 h revealed consistently high total as well as female abundance during monsoon than other seasons. The resting and feeding behaviors of frogs gradually decreased from day towards night, while croaking behavior gradually increased from 5 pm onwards and reached a peak at 8 pm and decreased further. Studies on the influence of environmental variables on the behavior of frogs in their native/natural habitats and in mesocosms will be rewarding to follow up their rehabilitation and conservation.
