摘要: This paper considers the sensitivity of population growth to small changes in birth, growth, survival, and migration probabilities for an arbitrary classification (i.e., age, instar, size, developmental stage, spatial location, etc.). The stage-specific life history parameters are expressed a discrete-time system linear difference equations, dominant eigenvalue which defines rate. this production class i by j individuals is shown be proportional product reproductive value stage abundance stable distribution. formula readily computable, several examples presented. For special case age-structured populations, reduces those derived Hamilton, Emlen, Goodman.
