碩士 / 國立屏東科技大學 / 野生動物保育研究所 / 92 / The aim of this research is to study the relationship between and community structure of the mayflies in riffles of low elevation areas in Taiwan. In total, there were 7 families, 16 genus, and 21 species of mayflies collected. The mayflies, Baetis spp., baetiella bispinosa, Pseudocloeon latum, and Caenis spp. were the dominant one in the studied streams. The average nymphal densities in the spring of 2002 and winter of 2003 was higher than that of the summer. The average total nymphal density had inverse correlation with the width, depth and flow of streams, respectively. On the other hand, the streams flow had positive correlation with the number of genus, the richness index, the diversity index and the degree of evenness. Torleya glareosa and Torleya lutosa showed rather stable larval size-frequency distributions throughout the study period. This indicated a possibility of asynchronous growth and continuous recruitment with multivoltine life histories.
