Generation time: a reliable metric to measure life-history variation among mammalian populations.

摘要: Abstract: Oli and Dobson proposed that the ratio between magnitude onset of reproduction (F/α ratio) allows one to predict relative importance vital rates on population growth rate in mammalian populations provides a reliable measure ranking species slow‐fast continuum life‐history tactics. We show choice F/α is arbitrary not grounded demographic theory. estimate position using first axis principal components analysis all variables studied by most individual perform as well ratio. Finally, we find, agreement with previous studies, age predictor along both body mass phylogeny markedly influence generation time species. conclude ratios such correlate ...
