Silver spoon effects are constrained under extreme adult environmental conditions
Early-life environmental conditions may generate cohort differences in individual fitness, subsequently affecting population growth rates. Three, nonmutually exclusive hypotheses predict the nature of these fitness differences: (1) silver spoon effects, where individuals born in good conditions perf...

Early-life environmental conditions may generate cohort differences in individual fitness, subsequently affecting population growth rates.

We quantified the context-dependent effect of early-life environment on subsequent reproductive success, survival, and population growth rate (k) of Svalbard reindeer, and explored how well it was explained by the three hypotheses.
