Our results do support though, that elevated densities can cause elevated stress levels in the individual, and we may speculate that persistent exposure to stress could have caused breeding reductions or survival reductions.
Results revealed a significant reduction in survival to eye (P < 0.001) and survival to fry (P < 0.001) for families sired using cryopreserved milt.
Notably, the reduction in survival following experimental infection, and the increase in survival following surface sterilization are roughly equivalent.
Further reduction in survival was observed in GNP-VS1 and GNP-VS2 cells with lesser survival with GNP_VS2.
Hence OXA-treatment results in a ~10-fold reduction in survival relative to controls, consistent with strong drug selection.
The authors of that particular study concluded that this reduction in survival rate seems to arise, at least in part, through psychosomatic factors – effectively, astrology can act as a nocebo.
Despite improvements in perioperative mortality rates, no studies have shown a long-term reduction in survival rates with EVAR over open surgery [65, 66, 67].
Lue et al. [36] showed how an imputed-spline modification to PHD yields an effective framework for conducting dimension reduction in survival regressions with censored data.
At intermediate RH, which the RH decreased from 90 to 40 60%, both ∆rpoS and ∆oxyR exhibited a higher log reduction in survival than the parental strain (Fig. 2).
