Document Summary
Bio 302 lecture 4 (september 18th): science of ecology ii. **reading questions for ch 1&2 (combined) are up on onq; the questions before 1230 mon day 25th. Focus on the one key factor to vary. Prediction when other species are present then they should be able to find new food sources. Ex: control: chickadees alone, experimental: chickadee w titmice. **from the paper: we need to manipulate flocking (the effect we are interested in , they manipulated the presence) , perf experiment, control they all move together in a flock, e(cid:454)per. The(cid:455) live together (cid:271)ut the(cid:455) don(cid:859)t flo(cid:272)k together. Infer the adaptive function of a trait by correlating its states across multiple taxa with variables thought to affect its evolution (eg. ecological selective pressures) Why do species flock together: h1. Species and how they would forage: h2. Observation: some birds lay intensely blue or turquoise eggs.
