BIO 3176 Lecture Notes - Lecture 17: Inbreeding Depression, Parthenogenesis, Matriarchy
Document Summary
Less to lose --> less costs --> more fighting. Can also see a "resident effect" with the vigorous fighting. Ferocity of fighting depends on what it has to lose --> cost --> depends on amount of time as a resident. At first, lot"s of jostling between fiddling crabs in beaches. Recognize boundaries and fight to establish the territory. Establish boundaries and don"t need to fight anymore. Don"t want neighbours to be replaced by intruder --> don"t want to re-establish borders. Will help their neighbours in a territorial bout if intruder is bigger. Fighting for territory again - defending the poplar leaf. Lays eggs in the leaf petiole thing to make a gall. Aphids will fight to get the part of the petiole closest to the leaf -->best part. Will kick each other with their hind legs for hours until one falls off the tree. Basal offspring = first at the optimum food thing, best.
