| Abstract | ||
| Mark Release Re-capture studies used in the evolution of animals and animal ecology. While it is probably to be used in some animals, it is considerably more challenging in small fast-moving invertebrate species, especially insects. In these groups, low rates of recapture can bias estimates of demographic parameters, thereby handicapping effective analysis and management of wild animal populations. The author used the mark-recapture method and daily movement of Ischnura elegans. The retention rate probability was different between males and females of Ischnura elegans. 969 individuals of Ischnura elegans (710 males and 259 females) were marked, recaptured and measured over the course of the study, of which 409 individuals (42.2%) 357 males and 52 females, were recaptured. The daily movement of Ischnura elegans shows, that 401 individuals were marked and 223 individuals were moved throughout the station or among stations. | ||
