Which of the following is an r-selected trait?
“Early semelparity” for which of the following is an r-selected trait. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Mechanistic support comes from showing how resource limitation, enemies, mate availability, or physiological stress changes demographic performance. A descriptive association alone does not establish regulation or causation. The remaining alternatives—“High parental care”, “Low fecundity”, “Stable population size”—refer to different states, processes, or scales and therefore do no
