Document Summary

What is the evolutionary history of the behavior: adaptive significance how are specific behaviors beneficial for species in different environments. Fields of behavioral research: ethology the stud(cid:455) of a(cid:374)i(cid:373)al (cid:271)eha(cid:448)ior, (cid:373)ostl(cid:455) pro(cid:454)i(cid:373)ate (cid:272)ausatio(cid:374). Ofte(cid:374) the (cid:862)(cid:449)hat(cid:863) a(cid:374)d (cid:862)ho(cid:449)(cid:863) of (cid:271)eha(cid:448)ior: behavioral ecology the study of how animals use behavior to survive and reproduce; mostly ulti(cid:373)ate (cid:272)ausatio(cid:374). Signal modalities of communication: communication the process in which actors use specially designed signals or displays to modify the behavior of reactors, acoustic, visual, chemical, electric, vibrational, tactile. Uses of communication: mate attraction, reproductive isolation (species specific, communication within a species, food, predators, status, territory, communication across species, between predatory and prey species, shared vigilance among prey. Sexual selection: process in which a heritable trait increases or decreases within a population based on whether the trait i(cid:374)(cid:272)reases or de(cid:272)reases a(cid:374) i(cid:374)di(cid:448)idual"s a(cid:271)ilit(cid:455) to o(cid:271)tai(cid:374) (cid:373)ates. Truggle a(cid:373)o(cid:374)g individuals of one sex to obtain mates of the other sex.
