Abstract
This study was carried out to compare the Snout-vent length (SVL) and the biomass for the endangered species II, narrow-mouthed toad (Kaloula borealis), at the three different latitude sites (Seoul, Nonsan, Busan) in Korea. For the narrow-mouthed toad study, pitfall traps and inducement traps were used to catch the species, and environmental factors (temperature, precipitation, humidity) were compared by region. As a result of this study, each of the male narrow-mouthed toads' SVL and biomass in Busan was 41.6±0.39mm, and 11.3±0.17g, which showed that it was the biggest and heaviest among the three regions. For Seoul and Nonsan, each of the SVL of the female narrow-mouthed toad was 36.6±2.03mm, 36.6±1.76mm, and the biomass was 8.1±0.55g, 8.2±0.91g, which showed that there was no significant difference between Seoul and Nonsan. Each of the female narrow-mouthed frogs' SVL and biomass in Busan was 44.7±0.35mm, 13.1±0.18g, which was also biggest but showed no significant difference in biomass by region. Concluding, this showed that the female narrow-mouthed toad in Busan is larger and heavier than those of other regions. We hope this study will be a standard for the future amphibian research with comparing the SVL and biomass for the endangered species II, narrow-mouthed toad. It is expected that if this kind of study keeps for long, it will be a basis for understanding changes in biomass of amphibian species due to climate change.
