The relative atomic masses on the periodic table include the contribution from different isotopes by taking a weighted average of the different isotopes' masses based on their abundance. Chlorine, for example, has two isotopes: chlorine-35 and chlorine-37. Three-quarters of the chlorine found in ...

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 ...
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...

In total, 471 proteins were identified across all samples; 199 protein groups showed altered relative abundance by day of lactation (fold change ≥2, P < 0.05), but none were altered significantly by parity. Higher relative levels of immune proteins were found in colostrum, and milk fat ...
