For your own research projects, you may want to look at last year's topics or at the abstracts of the talks and posters given at a meeting of the Animal Behavior Society for ideas. Some of the research reported there may be something you could replicate in the course of a semester.
Browse the abstracts from the Morehead meeting
Or download all of the abstracts as one big
.pdf file
If you don't already have it, you will need to download
Adobe Acrobat Reader
to view the big .pdf file.
