1 Animal Behavior Chapter 51

2 Def: The study of how specific behaviors increase reproductive success a)Learned behavior (nurture) – environmental and ecological basis b)Innate behavior (nature) – genetic and evolutionary basis 1)Natural selection favors a behavioral phenotype 2)Genotypes that do not increase fitness eliminated from gene pool I. Behavioral Ecology Play

3 II. Types of Behavior a)Instinct: Inherited, __________ behavior b)FAP (_____ _____ _______): Sequence of behavior that is unchangeable and carried to completion once started 1)External sign stimulus triggers FAP Ex. Stickleback fish Ex. Greylag goose innate fixed action pattern

4 II. Types of Behavior c) Habituation: loss of responsiveness to stimuli that convey little or no information 1)simple form of ___________ Ex. Sea Anemones d) Imprinting: learning that is limited to a very specific _____ _____ of an animal’s life 1)Irreversible 2)Imprinting stimulus Ex. Salmon Ex. Ducklings Ex. Whooping Cranes learning critical period Play

5 II. Types of Behavior e) Associative Learning: ability of animals to associate one stimulus w/ another 1)Classical Conditioning (arbitrary stimulus) Ex. Pavlov’s Dog 2)Operant Conditioning (Trial and Error) Ex. B.F. Skinner’s rats f) Observational Learning – modeling g) Spatial Learning – memory of environment’s spatial structure h) Insight – cognition and problem solving i) Prior experience helps an animal exposed to a new situation Play

6 III. Oriented Movement a)Kinesis: an undirected change in speed of an animal’s movement in response to a stimulus b)Taxis: a directed movement in response to a stimulus c)Migration: long-distance seasonal mvmt

7 IV. Social Behavior Evolved to optimize individual fitness

8 IV. Animal Signals and Communication Important for species recognition, mating, organizing social behavior Occurs through visual, auditory, tactile, and chemical means (pheromones)

9 V. Social Behavior a)Agnostic behavior (aggression and submission) 1)ritualized contests 2)determines who gains resources food, mates 3)Can be psychological rather than physical 4)Establishes dominance hierarchies (pecking order and territoriality Play

10 b) Altruistic Behavior selfless and/or sacrificial behavior that seemingly reduce the fitness of the individual… V. Social Behavior increases inclusive fitness = the fitness of relatives who share identical genes Natural selection that favors altruistic behavior = Kin Selection
