 note = {After accounting for the density dependent variation, annual differences in lamb growth rates were positively related to the increase in biomass of live grasses and forbs between spring and summer. Since food availability was influenced strongly by the numbers surviving the winter, lambs born after the very high mortality at peak population density were able to compensate to some extent for their poor initial growth. However, improved food availability was never sufficient to facilitate complete catch-up growth and may permanently influence adult size and reproduction.},
