Document Summary

2: want to explain/understand ecological processes, most interested in the processes of birth, death and migration, immigration to settle, emigration leaving, these processes are important because they alter the distribution and abundance. Two classes of explanation: proximal: patterns explained by the present environment, eg. How did the weather (eg. rain) this summer influence plant growth in the region: growth, hazards, ultimate: patterns explained by the past environment (i. e. ecological experiences of ancestors through evolution, eg. Observation/discovery: 1st step: discover patterns and interconnections through observation, exposing yourself out in the environment. Question: 2nd step: question the pattern and interconnections that are observed, what questions that describe patterns or relationships, what part of the tree does each bird species occupy? . We do not accept it: due to confounding variables, especially in changing ecosystem, example, h0: bird species are not distributed according to their preferred prey type, ha: bird species are distributed according to their preferred prey type.
