英文摘要

From April 2002 to March 2006, we studied the distribution and population dynamic of Alishan salamander (Hynobius arisanensis) in Alishan Areas. We surveyed 73 sectors of wasabia plantation at 36 forestry areas around the Alishan areas, and found Alishan salamander in nine of them. Common characters of these localities were having a gradual rise slope and with small creeks. We use the area-constrained method to monitoring population dynamic in the Sister Ponds population. A total of 266 salamanders were captured in four years periods, with 94 recaptured salamanders. We used the Jolly-Seber method to estimate the monthly population size, it ranged between 13 and 305 individuals. It seemed that population size does not decreased as comparing with those estimation made by the former researchers. Most captured salamanders were adults, while juvenile were captured irregularly, and metamorphs only appeared in spring. Estimated home ranges of Alishan salamanders in the Alishan areas ranged 0-509 m? (64.9 ± 29.6m? (n = 19)). We used the Cormack-Jolly-Seber model to modeling the survival and capture probability. The survival probability were constant, adults and juveniles were 0.996 and 0.997, respectively. Capture probabilities were seasonal-specific, the capture probability were significantly positive correlated with seasonal rainfall. Using the Leslie matrix model to investigate the population dynamics and to determine population growth rate of this population, it was 1.077, indicating that the population is stable and slow growth. The sensitivity and elasticity population growth rate both indicate that the adult survival rate was the most important vital rate for the population stability.
