In the current risk assessment of herbicides for nontarget plants no reproduction effects are considered, and therefore, it seems that herbicide effects on wild plants species are potentially underestimated.
However, T-invariants do never neglect trivial T-invariants which reflect exactly such local reproduction effects.
Ribozyme populations therefore can -- by means of indirect reproduction effects -- evolve a mutational robustness [ 57], a behavior that empowers selection with an advantage relative to other evolutionary forces (e.g., the strength that random drift has in populations of small effective sizes).
To prevent plague in prairie dogs, the NWHC, in partnership with the University of Wisconsin School of Veterinary Medicine, developed and tested (for efficacy, safety, duration of immunity, reproduction effects and efficacy, and safety in non-target species) a recombinant vaccine against plague using a raccoon pox-vector (RCN) to express the F1 and Vt antigens (Rocke et al. 2010).
In contrast to male reproduction, the effect(s) of 35S NTAP AtCTF7∆B on female reproduction are observed earlier and are more variable than those in atctf7 and AtCTF7 RNAi plants.
Because many life history traits of this primate are highly dependent on the photoperiod (body mass and reproduction), the effect of season was also assessed.
At a concentration of 1142 mg/kg, TNT caused significant toxic effects in all test methods, but at lower test concentrations no significant acute or reproduction toxic effects could be observed.
Chaima: Yes God's creation constituted the first-degree of diversity then sexual reproduction, mutations, effects of environmental factors etc. constitute the second-degree of diversity. .
