Aluminium is low in density.
Lead has a high density.

[ C ] Lead has a high density.
Patches with high densities of adult or juvenile trees will produce more leaves and possibly attract more herbivores.
They will be less important in the tabonuco, where bromeliad densities are very low.
Seed-bank densities per quadrat were evaluated using three surrounding soil cores.
Such variation in population densities did not lead to extirpation because there was sufficient habitat in other parts of the marsh.
Note the different scales for seedling densities and plant cover for the different species.
Moderate densities were seen in medial area 9 and lateral area 12, and considerably lower densities were seen in all other prefrontal areas.
In our new approach we allow the ions to have different par tial densities.
To match the empirical spectral densities, the magnitude of the variance of errors must represent more than 60% of the magnitude of the data variance.
