摘要

Mangrove is the most unique and important wetland ecosystem of the tropic and subtropic coastal forests. It is imperative to monitor its environmental conditions and index species. We used a wireless sensor network system to determine the relationships between the fiddler crab population and environmental variables, humidity, temperature, tidal levels, and seasons, at the Danshuei River Mangrove Nature Reserve in Taiwan. The results showed that the crab population was positively correlated with temperature (r=0.407, p＜0.01) but negatively with humidity (r=-0.376, p＜0.05) and tidal level (r=-0.563, p＜0.01). Also the population changed significantly with seasons (F0=16.551); the population was larger in summer than in autumn and winter. In other words, the crabs were more active at low humidity and higher temperature. This wireless sensor network system was recommended as a long term monitoring system of coastal mangrove wetland habitat and the index species for the conservation purpose.
