Temperature (16, 20, 24 and 28 °C) affected significantly average lifespan (LS), life expectancy at hatching (e0), generation time (T), net reproductive rate (R0), intrinsic rate of population increase (rm) and population growth rate of A. brightwelli, prey (B. angularis) density (10, 20, 30 and 40 ind. ml-1) affected the values of T, R0, rm and r, and their interaction affected the values of T and r. In natural water bodies, the dynamics patterns of A. brightwelli population, and then the community structure and the functioning of ecosystems will be changed by climate changes.
