Chlorpyrifos increases intrinsic population growth rate in B. calyciflorus.
“In contrast, chlorpyrifos exposure elicited hormetic responses, shortening the time to the first brood and increasing the intrinsic population growth rate.”

Chlorpyrifos protects against survival in B. calyciflorus.
“the heat spike-induced reductions in survival, fecundity, lifespan, the proportion of rotifers producing offspring, and the intrinsic population growth rate were no longer significant when combined with subsequent chlorpyrifos exposure.”
