On the other hand in vivo concentrations of triclosan could be lower, potentially transient and acting on bacteria with greater generation times.
In the naturally-isolated tributary, persistence was associated with higher early juvenile survival (∼45% greater), shorter generation time (one-half) and strong selection against large body size compared to the open system, resulting in a stage-distribution skewed towards younger, smaller fish.
In conclusion, N inputs improved all ecological fitness traits of BPH providing greater survival, shorter generation time, and larger body size.
This burden is even greater if the generation time of the plant is much longer than the generation time of the pathogen.
However, some biological characteristics inherent in Chinese fir, such as long generation time, great tree height, high genetic load and inbreeding depression [ 2], have seriously hindered progress in the nurturing of new varieties through conventional improved technologies.
Probably in vivo concentrations drug concentrations can be lower and potentially transient and the bacterial generation time is greater.
Under a model where fluctuations were shorter relative to generation time, selection favored greater physiological tolerance or plasticity (Turelli and Barton 2004).
The alternative argument is that the microscopic size of protists allows greater opportunity for cosmopolitan existence, but at the same time factors such as their sheer abundance, short generation time and ability to reproduce asexually allows for greater endemism [4].
Neil Howe, a generational expert whose books include "Millennials Rising: The Next Great Generation," says Our Time has the potential to be "the political and social movement equivalent of Groupon".
The great hammerhead is extremely vulnerable to overfishing due to its low overall abundance and long generation time.
