BIOL 304 Lecture Notes - Lecture 26: Cleaner Fish, Hawk And Dove, Nibble
Document Summary
Hawk & dove balances can be traced down to genotype in hydractinia colonies. Similar genotypes will meet in a shell & fuze together. If different genotypes meet, each colony secretes polymers into environment, shadding themselves from other colonies. Public resource cannot be monopolised by one individual. Don"t want too many scroungers nothing really happens. Cooperation public good ressources where everyone must interact with the ressoucre, little interaction between individuals. How to explain behaviors where no immediate gain from interaction. Many bats don"t get blood-meal every night, but must eat. Beg colony mates for bloodmeal, provided by regurgitation usually. If fish eats cleaner fish, others will avoid it and not remove parasites. Cleaner fish might also cheat and nibble on host. Explore cooperative systems, undertand cooperation since cannot be explained by pure natural selection. Judging for matrix, cheating would be the best strategy! Prisoner dilemma ran computer simulations, big leap between top strategies & lower strategies.
