Population dynamics of Hetaerina rosea Selys and its relationship to abiotic conditions (Zygoptera: Calopterygidae)
Odonatologica , Volume 33 - Issue 1 p. 73- 81
Aspects of population dynamics were tested against temperature, insolation and moisture. The monthly abundance of H. rosea was estimated utilizing a scan method based on 49 fixed areas in 30-min intervals from 0800 to 1700 h during the day. The daily <3 activity pattern is characterized by a sharp increase at 0900 h with continuous density until 1430 h, followed by a sharp decrease after 1600 h. A correlation between peak densities was observed during the year and high period of photoperiod and low evapotranspiration suggesting possible ways S 6 can adjust their emergence periods to optimize water loss with longer reproduction periods of activities.
