This project will answer broad questions regarding spider evolution and ecology. Spiders are one of the most successful predators on Earth - there are over 40,000 known species, compared to only about 5000 species of mammals! They are an integral part of a healthy ecosystem, however, little is known about the role spider morphology plays in determining an individual's fitness. This study is the first to apply ecomorphological techniques to answer questions about a spider's functional ecology.
