Document Summary
Life history: lifetime schedule of reproduction and survival. Life history trait: trait that contributes directly to offspring production and survival (linked by physiological tradeoffs) E. g. growth rate, age of 1st breeding, # of offspring, size of offspring, life span, rate of senescence. Qualitatively and quantitatively different from other types of movement. 1 of 2 movement types taking individuals outside their home range: home range: areas where organisms live and reproduce, depends on body mass and diet (e. g. carnivores larger range) Stasis: demonstrated by animals that never move or only move during larval / gamete stage (e. g. tunicate) Station keeping: movements that keep the animal within home range; associated with vegetative functions like growth and repro. Kinesis: simple changes in rate of movement or turning: long axis of body randomly directed to stimulus (e. g. insect zigzag pattern) Taxes: directed movement where long axis of body shows consistent relation to stimulus.
