Examples of densitydensity Generation of multiply charged ions at low and high laser-power densities. All flies were reared in bottles at low larval densities. Population densities were estimated every 3 d by means of a vertical tow. There are, however, technical difficulties with using simulated tempering schemes, particularly with regard to setting up the modified densities and their pseudopriors. From the equation of state the two number densities nuare also known. Clutches used to found the 10 pair and control lines were culled randomly to keep larval densities equivalent in all lines. The output was striking; most of the papers are highly technical - entropy functions and probability densities abound. 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. In our new approach we allow the ions to have different par tial densities. Moderate densities were seen in medial area 9 and lateral area 12, and considerably lower densities were seen in all other prefrontal areas. Note the different scales for seedling densities and plant cover for the different species. Such variation in population densities did not lead to extirpation because there was sufficient habitat in other parts of the marsh. Seed-bank densities per quadrat were evaluated using three surrounding soil cores. They will be less important in the tabonuco, where bromeliad densities are very low. Patches with high densities of adult or juvenile trees will produce more leaves and possibly attract more herbivores.
