ORIENTATION TO BLG 567 INTRODUCTION TO ECOLOGY LECTURE 1: WHAT IS ECOLOGY & WHY STUDY IT? Text Reading: Chapter 1
How can you test this hypothesis? 1. Natural Experiment: find streams with differing abundances of snails and crayfish, and measure periphyton abundance. 2. Manipulative Field Experiment: divide several streams into segments and manipulate the snails and crayfish to give a range of abundances, then measure periphyton abundance. 3. Laboratory Experiment: establish experimental streams in the lab which have differing abundances of snails and crayfish, then measure periphyton abundance. Null Hypothesis : Snails and crayfish don’t exert strong effects on the abundance of periphyton.
Overall - Which Approach is Best? A. Natural (non-manipulated) Field Experiment B. Manipulative Field Experiment C. Laboratory Experiment D. All of the Above E. None of the Above Photo credit:

Today’s topics Why get involved in research? How to get involved in research? What research is going on here? How can I get involved in research elsewhere?
Why should you get involved?
Why get Hands-On Research Experience? Science is pretty fun (hence research often is, too!), You are at university to get more experience and get smarter (more knowledgeable) – participating in hands on research will contribute to your education. You will have a better chance of getting a job if you increase your experiences and knowledge . It’s all about networking!
Why get Research Experience? You will learn a new set of science-y techniques , You’ll learn how to solve problems because you’ll know who to ask and how to hunt through the literature , Practice builds confidence that tools exist, and when tools are missing, you’ll know that they can be developed (by you, if needed), Research projects give you the practice of doing science, giving you a fluency that you can’t get just by absorbing sciency wisdom from lecture courses.
Why get Research Experience? You will learn how to collect and analyze your own data , You will learn to communicate about science (yours and other people’s), All this practice, develops confidence that you can do science. Confidence like this will make graduate school more enjoyable, and is equally useful for other careers that may involve collecting and dealing with data, The research life can plug you into the social scene associated with your major.
