Christopher Brown - Is Autotomy Costly? A Tale of Spiders, of Legs Lost, and of What Comes After
Autotomy is defined as the intentional sacrifice of a body part, and is usually done to avoid being eaten after an animal has been grabbed by a predator. This is obviously beneficial, since loosing a body part is better than losing your life! However, missing this body part may prove costly in the future. In this talk I examine leg autotomy in the wolf spider Pardosa valens from Arizona, and show how the loss of a leg can affect this spider's running speed on both its short-term and long-term survival.
