Q

fixed action patterns: male stickleback example

A

male sticklebacks are territorial and attack other males with red undersides

operant conditioning: animal associates…

A

its behavior with outcome

39
Q

operant conditioning:
repeats behavior with ___ outcome
avoids behaviors with ___ outcome

A

positive; negative

40
Q

most complex forms of learning involve

A

cognition

41
Q

cognition includes:

A

awareness, reasoning, recollection, and judgement

42
Q

cognition pulls multiple sources of information together to…

A

make decisions

43
Q

problem solving:

A

determine how to move form one state to another using a series of behaviors

44
Q

problem solving is __ focused

A

objective

45
Q

social learning

A

learning through observing others

46
Q

most common in social species

A

social learning

47
Q

social learning is similar to associative learning but…

A

thought the experiences of others

48
Q

example of social learning

A

chimpanzees learned to crack nuts by watching parents

49
Q

social learning is the basis of

A

culture (info is passed down through generations)

50
Q

continuing behaviors must be selected by

A

natural selection: increased survival and reproduction

51
Q

cost benefit analysis

A

balance between cost and benefits

*Cost of finding food VS Benefit of nutrition

52
Q

natural selection favors optimal foraging:

A

maximize benefits and minimize costs

53
Q

example of optimal foraging

A

crow foraging: fly to optimal height to break shell open
-makes sure they get the food without expending too much energy

54
Q

foraging increases risk of…

A

predation

55
Q

why do mule deer forage in meadows instead of forests, where there is more food?

A

mule deer are eaten by cougars which prey along forest edges, they feed in open meadows to compromise between selective pressures

56
Q

promiscuous partners

A
  • No long-term pair bonds
  • Mate with different partners each year
  • Mate with many partners in one season
57
Q

monogamous species

58
Q

polygamous species

A

59
Q

polygyny

A

one male, many females

60
Q

polyandry

A

one female, many males

61
Q

63
Q

sexual dimorphism: females are more ornamented in __ species

A

64
Q

needs of young influence

A

mating system

65
Q

for young that require lots of parental care…

A

both parents remain to make care of young

66
Q

for young that can fend for themselves immediately…

their father

intersexual selection: often always ___ species

A

polygamist

74
Q

intersexual selection often involves __ behaviors

A

agonistic (contest for a resource)

75
Q

do agonistic behaviors result in extreme or mild injuries?

A

mild

76
Q

intersexual selection results in males with..

A

similar characteristics

77
Q

some species have males of various phenotypes, each phenotype..

A

has a different strategy for reproduction

78
Q

behavior is partially controlled by

A

genes

79
Q

genetics of behavior: garter snake example

A

coastal snakes eat slugs and inland snakes do not, despite being born in a lab

80
Q

altruism

A

a behavior that harms you while helping others

81
Q

altruism decreases one individual’s ___ while increasing another individual’s __

A

fitness

82
Q

the highest evolutionary advantage is to

A

have your genes the next generation

83
Q

there are 2 ways for your genes to be in the next generation:

A
  • You reproduce directly: 50% of your genes in children
  • Your close family reproduces
84
Q

inclusive fitness

A

combination of personally passing on genes AND close family passing on genes

85
Q

kin selection

A

natural selection favors enhanced reproduction of close relatives

86
Q

ground squirrels: why are females more likely to give alarm calls?

A

o Females save family
o Males save strangers

*risk her own survival to increase survival of relatives

87
Q

eusocial insects appear to have extreme altruism:

A

o Often only 1 individual reproduces
o Most individuals serve colony without reproducing

88
Q

eusocial insect’s extreme altruism involves

A

haplodiploidy
o Females are diploid
o Males are haploid

89
Q

results of haplodiploidy

A

 Parents and offspring share 50% of genes
 Siblings share 75% genes (on average)

90
Q

haplodiploidy: helping mother create more siblings passes your genes (more or less?) than reproducing yourself would
