BIOB50H3 Lecture Notes - Lecture 2: Field Experiment
Document Summary
You need to have very clear structure: like location, time, how, etc. Using the appropriate method can make this form of study powerful. In these conditions the experimenter can control all the variables. Its challenging to observe ecological processes through capacity. Science is a series of steps, it gives us a method to answer questions, to obtain knowledge, not just believe. Belief and knowledge are separate things but are both important in science. You rst make an educated decision, then you attempt to test it, carry out an experiment, then you analyze the data, and then you come to a conclusion. When ecologist observe things, they design methods to test it (experiments, observations, models) Concept: ecologists evaluate competing hypotheses about natural systems with experiments, observations, and models. Because of the complexity of testing hypotheses, ecologists design various way of testing these hypotheses.
