A disadvantage of seedless patches within the seedbank would be a reduction in the availability of seeds for seedling regeneration following disturbance, and an increase in density-dependent mortality associated with clustered seed deposition patterns (Russo 2005).
It could, however, have important implications as the overall attack rates are expected to increase with increasing household size in a density dependent model but remain approximately constant in a frequency dependent transmission model.
So, if only the density varies, then inner regions do have higher pressure but the increase in density also increases the force of gravity, because gravity is dependent on how much mass there is.
The dependant lung should increase in density.
It is a dramatic increase in density.
Another view holds that exploitation by overwhaling had virtually no effect on the size of the bull sperm whales, and their size may have actually increased in current times on the basis of density dependent effects.
The increase in sapling clustering did not increase density-dependent thinning, and persisted into older recruit cohorts, suggesting that hunting may initiate long-term spatial reorganisation of Amazonian tree communities.
Hence, we hypothesize that higher plant density due to lower abiotic mortality could increase intraspecific density-dependent mortality in coastal populations.
For instance, the density-dependent build up of specialized herbivores or pathogens may prevent a species from continually increasing in density, thereby maintaining diversity in the system (Janzen 1970).
Moderate increases in density don't mean town cramming.
Increased growth rates in pups may reflect a density dependent response to declining reproductive rates (e.g., decreased competition for resources).
