Document Summary

Behavioral ecology is the study of the ecological and evolutionary basis of animal behavior: animal"s behavioral decisions play critical role in activities (e. g. , obtain food, find mates, avoid predators) These decisions have costs and benefits that affect an individual"s ability to survive and reproduce. Proximate causes: immediate & individual level: how the behaviour occurs, ultimate causes: evolutionary & species level, why the behaviour occurs, behavioural ecologists most focus on ultimate causes. F1 generation can give rise to viable offspring get mix of 2 diff genotypes: when offspring burrow, all the tunneling had long tunnel entry and has the scape tunnel, very similar to oldfield mice. F2 generation these offspring will have a mix of burrow types that they build: long entry w escape tunnel and some w short entry tunnel suggesting it"s a single gene that"s responsible for this behaviour.
