Abstract
The population carbon budget and seasonality of Boeckella minuta in a newly formed subtropical reservoir were examined 3 years after the reservoir filled. Average daily biomass was 26.4 mg C m−3 and the annual population carbon budget was: consumption 2470, egestion 1482, assimilation 988, production 493 and respiration 495, mg C m−3 year−1, and the average P/B and P/A ratios were 0.08 and 0.5 respectively. Clutch size and reproductive effort (egg production/assimilation) were low, and the proportion of males decreased throughout the population cycle. The seasonal abundance pattern changed from perennial (pre-filling years) to a 7 month cycle. It is suggested that eutrophication and the spring bloom of cyanobacteria may have accentuated a seasonal decrease in reproductive effort and survival, leading to an absence of planktonic stages during summer, and that resting eggs facilitated population survival during the summer period of stratification.
