However, when the eggs in the top and bottom were compaired to the once placed in the middle a slower die-off rate was observed, in the middle a 27% survival was reached after only 46 days storage which was 30 days prior to the date when the same die-off was reached in the bottom and top samples.
The off rate is 1.5 s–1.5
ENT die-off rates have been shown to be reduced in sand compared to water, and rates can differ in sand and water between strains of ENT from different sources.
This could therefore explain why a fast die-off rate of eggs was seen in the beginning of the experiment in the heaps with the strongest decline in the content of organic nitrogen, i.e. free ammonia would have caused a kill-off effect before it volatilized.
From the onset of the experiment, the die-off rate of A. suum eggs was highest in the heaps with the highest pH values.
For all the chlorophyll-a concentrations used, significantly higher die-off rates of FC were observed in light compared to darkness (p < 0.001, Fig. 1).
A potential problem associated with assaying mortality rates of beetles housed in groups is that estimates of mortality rates can be influenced by densities declining at different rates among genotypes, as individuals die off.
Once their job is done, they die off.
That is why they eventually die off.
Once the infection has been brought under control, most of the CD8+ T cells die off.
Harlequin frogs have been dying off at such a rate that they're mainly seen now in zoos, and last year a research team identified global warming as the "trigger".
