Document Summary
You"(cid:448)e disco(cid:448)ered a (cid:374)e(cid:449) species of a(cid:374)i(cid:373)al high i(cid:374) the (cid:373)ou(cid:374)tai(cid:374)s (cid:449)here conditions are variable, unpredictable, and frequently difficult. Between number of offspring and their maturity at. More eggs -> less stored energy in each. Parity (number of times your reproduce in your lifetime) Fecundity (how many kids you have at a time or over your lifetime) Long lived: expect to reproduce annually for many years -> late maturation, grow instead. Short lived: must reproduce quickly, higher proportion of energy goes to reproduction. Number of episodes of reproduction in a lifetime. Do not confuse with life span terms: annuals - live one year (typically reproduce once) Biannuals - live through at least one non-breeding season (typically reproduce once) Semelparous - reproduce only once (not the same as annual) Reproductive traits that vary with life history patterns - frequency. Live and reproduce over many years, repeat reproducers. Determinate growth - no increased fecundity with size.
