Is Starvation Density Dependent?

coli bacteria maintained a population of viable cells at a constant level through recycling activity, by quantitatively estimating the death and growth rates during starvation. ... Interestingly, this behavior is highly dependent on the population density of the viable cells.

Is starvation density dependent or independent?

The density effect is mediated by chemical signal(s) that worms release during starvation. This starvation survival signal is independent of ascarosides, a class of small molecules widely used in chemical communication of C. elegans and other nematodes.

What are some examples of density dependent factors?

Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.
