Density is commonly expressed in units … WebThe effects of changing the baryon density (Fig. 9.17) are a shift in the peak locations, due to the change in the sound horizon r s (η ⁎), as well as modifications in the heights of the peaks.We have already touched on the ways in which the anisotropy spectrum depends on the baryon density. The foremost, clearly visible in Fig. 9.17, is that the ratio of the …

Johnson, in Encyclopedia of Biodiversity (Second Edition), 2001 Local Abundance. Population density is generally not well represented in the fossil record, but patterns of extinction of populations on land-bridge islands and in the present day show that local extinction is more likely for species with low population densities.
