摘要

Life history and secondary production of E. ignita were determined in two reaches of the Aguera stream (northern Spain). Production was much higher (> x 2) at the reach where the nymphs hatched earliest. However, there was no evidence to support a link between E. ignita production and timing of the recruitment, as in both reaches it achieved similar mean individual weight and biomass turnover rate. Thus, the site-dependence of E. ignita production was a consequence of spatial changes in density. [References: 37]
