Chlorpyrifos

1. Chlorpyrifos shortens lifespan in C. dabryi.

   “chronic low-dose chlorpyrifos exposure induced telomere degradation and reduced survival in a dose- and physiological age-dependent manner”

3. Chlorpyrifos protects against lifespan 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.”

1. Chlorpyrifos decreases telomere length in C. dabryi.

   “Field investigations showed that fish populations of lake skygazer (Culter dabryi) with chronic low-dose chlorpyrifos loads had shortened telomeres”

1. 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.”
