Why do different animals use different "chanels" for communication?
Which chanels carry what types of information best?
How do communication systems evolve?
To what extent, or how, does the environment shape the evolution of communiction systems?
What is meant by Code Breaking?
I changed my mind. Originally I'd required the Endler and Basolo paper which is a much more rigorous paper but on second thought... it is a bit too complicated for right now. This Ryan paper gives an overview that will be more useful in terms of the way we are discussing Communication

Migration and Orientation
Amazing migrations require amazing mechanisms. We will talk about why animals migrate as well as how animals migrate. Much of migration relies upon accurate orientation and navigation. Consider how it is that you know where you are and where you are going? Without a map, what cues could you use?
How are these migrations accomplished? What physiological changes occur in the animals? How do they know the route? What is the role of genes in establishing migration routes?
