Abstract
Amphibians are sensitive to environmental changes and are showing a severe decline worldwide. Amphibians are known as indicator species sensitive to environmental changes. The bullfrog, which has been introduced into Korea and has spread nationwide, is an amphibian sensitive to environmental changes and an alien organism requiring management measures, and has very important research value. In reality, research on bullfrogs has many limitations in terms of time and cost. In this paper, we estimate the variation in the behavior of the bullfrog ecological features of the bullfrog presented in several papers. The stage of growth over time was applied to the continuous-time Markov chain model to estimate the transition probabilities and mean survival time. In particular, the average survival time to death at each stage was 104.825 days for eggs, 520.125 days for tadpoles, and 2920.0 days for adults.
Keywords : Bullfrog, continuous time Markov chain model, continuous transition probability, transition rate matrix.
