in the atmospheric column over the Arctic region, observed during the 1990s,, resembles the onset of the Antarctic ozone `hole' in the mid-1980s, but the two polar regions differ significantly with respect to the relative contributions of chemistry and atmospheric dynamics to the ozone abundance...
abundance (RSA) in the local community under restricted immigration. Here we present a theoretical framework for the unified neutral theory of biodiversity2and an analytical solution for the distribution of the RSA both in the metacommunity (Fisher's log series) and in the local community, where ...
From this perspective, the set of dinucleotide odds ratio (relative abundance) values constitute a signature of each DNA genome, which can discriminate between sequences from different organisms. Dinucleotide-odds ratio values appear to reflect not only the chemistry of dinucleotide stacking energies ...
This normalization procedure approximately cancels out any variations in the isotopic abundance except those due to nuclear processes. Measurements on enriched standards showed that any variations greater than 1% would certainly have been detected, and variations greater than % would probably have been ...

5E). Corticotrophin-releasing hormone receptor 1 (Crh-r1) transcript abundance in pituitary was not different between genotypes (Fig. 5A); however, Crh mRNA in the PVN (Fig. 5B) and arginine–vasopressin (Avp; Fig. 5C) mRNAs in the hypothalamus were both lower in abundance in 5αR1-KO...
