1 Animal Behavior

2 Ethology Study of how animals behave 4 main questions
What stimulus elicits a behavior and what physiological mechanisms mediate a response? How does the animals experiences during development influence the response How does the behavior aid survival and reproduction What is the behaviors evolutionary basis.

3 Behavioral Ecology Study of the ecological and evolutionary basis of behavior Proximate cause – focuses on immediate causality (how it happens) Ultimate cause – focuses on the bigger picture (why it is evolutionarily beneficial)

4 Movement Kinesis – change in activity due to a stimulus
Taxis – orientation towards or away from a stimulus

5 Migration Migration – a long distance change of locations done at regular intervals Usually stimulated by seasonal changes Use the sun, north star, or the earth magnetic field

6 Rhythms Circadian rhythms – daily cycles (rest, eating, etc), usually regulated by light and dark Circannual rhythms – yearly cycles usually linked to seasons. Cortisol, released by the adrenal gland

7 Signaling Usually, visually, chemical, or auditory

8 Instincts Innate behavior – fixed behaviors that all the
animals in a population are born with (instinct) Fixed action pattern – a sequence of innate behaviors initiated by a stimulus.

9 Learning Habituation – a reduction or loss of reaction to a stimuli (crying wolf)

10 Imprinting Imprinting – a life long reaction or bond to an object or individual created at a young age Usually a baby raised by a different species mistakenly believes he is of that species

11 Spatial Learning Spatial learning – able to remember the structures in
an environment (using landmarks)

12 Cognitive Maps Cognitive maps – a memorized mental representation (map) of an environment. (do not have to rely on land marks.

13 Associative Learning Associative learning – the ability to connect two environmental factors as being related (color and taste) Classical and operant learning

14 Classical conditioning
Classical conditioning – a stimulus elicits a response Povlov’s dog – ringing a dinner bell before dinner causes the dog to salivate without food being present

15 Operant Conditioning Operant conditioning – an animal connects his behavior with a good or bad response (trial and error) Pups or cubs with porcupines

16 Cognition Cognition – the ability to think, reason and process information. Cognition can be used to problem solve

17 Selection and Survival
Most behaviors are ultimately formed by natural selection for survival and reproduction

18 Foraging Foraging – activities and strategies an animal uses for survival. optimal foraging model – benefits should outweigh costs

19 Fight or Flight The decision to fight or run is also measured by risk and reward (benefits should out weight costs)

20 Mating Systems Promiscuous – no mating bonds
Monogamous – strong bond forms one male one female for a long period Polygamous – one sex mates with others Polygyny –the males mate with many females Polyandry – the females mate with many males

21

22 Antagonistic behavior
Competition to gain access to a resource.

23 Game theory Evaluates the success of strategies used when the strategies depend on other strategies (paper, rock, scissors.) Orange aggressive, blue small territory, yellow sneaky

24 Altruism Altruism- animals reduces their individual fitness to increase the population fitness Inclusive fitness – total of an individual getting their genes into the next generation through their own offspring or a relatives offspring. Kin selection – selection favors altruism

25 Social Learning Social learning – an individual learns by copying the behavior of a more experienced individual. This breeds culture. Passes behavior to increase fitness

26 Mate choice copying Mate choice copying – females choose mates that other females find attractive
