Q

what are Tinbergen’s 4 questions?

A
  1. ontogeny- how did behaviour develop, learned or innate?
  2. causation- stimuli and mechanisms, causal factors
  3. adaptive significance- current function, increase fitness?
  4. evolutionary history-why evolve like this

Q

a) what did von Frisch discover?
b) what is his odour theory of communication?
c) what was the real reason for the behaviour?

A

a) dance language of honey bees
b) that the bees waggle dance can spread smell of sugar water
c) dance orientated around the sun and could communicate distance and direction

Q

a) what did Lorenz find when he studied three spined sticklebacks?
b) what was the man species he studied?

A

a)males red throat is a signal to other males
females swollen belly signals males to trigger courtship
b) courtship in ducks- displays differ depending on species

Q

what is MHC- major histocompatibility complex?

what attracts someone by it?

A

set of genes concerned with fighting disease

someone with a different set of MHC has a more attractive smell (complimentary)

Q

in Thorpes study of chaffinches what was found/done for the question of ontogeny?

A
  • females could hear sounds of males at different times during development
  • few months after hating is when most likely to learn song- sensitive period
  • song is partly innate and partly learned from tutor

Q

in Thorpes study of chaffinches what was found/done for the question of causation?

A

light triggers bird song in spring
light reaches pineal gland which has light sensitive cells
brain releases GnRH leading to growth of testes
more testosterone released so song occurs

Q

a) in the bird brain what is the Robust archistriatum (RA)?
b) what is it connected to and what does this do?
c) why do males tend to have a larger RA?

A

a) part of the brain concerned with song
b) connected to HVC (higher vocal centre) which sends nerve impulses to syrinx via NXIIts
c) are the ones that sing so the larger the RA the more complex the song

Q

what are the 2 hormones cause hunger and when and where is each released?

- released from fat storage cells
- if more of these cells more leptin released into blood by hypothalamus
- less hunger
Ghrelin
- released when leptin levels low
- released from stomach via hypothalamus

79
Q

whats the altruistic behaviour of geldings ground squirrel?

A

give loud alarm call when sees a predator but is risky as means the individual is more likely to be predated

80
Q

what type of selection is :
selfish
altruism

A

selfish: direct
altruism: indirect

81
Q

where is testosterone produced and in response to what?

what does it stimulate?

A

in testes in interstitial cells in response to glycoprotein produced in anterior pituitary in brain
stimulates reproductive behaviour

82
Q

what are individuals like who have higher endogenous testosterone levels?

A

more aggressive/dominat

83
Q

when do testosterone levels tend to increase?

A

in anticipation of aggression- priming effect

after aggressive incident- feedback loop

84
Q

in copperhead snakes what is the effect of the stress hormone corticosterone?

A

losers have higher levels

losers less likely to want to fight again or court females

85
Q

whats the difference between between type A and B people in the human dominance hierarchy?

A

A: more responsive to challenges, dynamic, hyper, die sooner, more mates

86
Q

what are the 5 types of aggressive behaviours?

A
  • male-male contact
  • sexual cannibalism
  • siblicide
  • infanticide
  • child abuse
87
Q

describe sexual cannibalism in praying mantis

A

female eats mate during/after copulation

females that eat males lay 30% more eggs

88
Q

describe siblicide in eagles

A

older chick pushes younger out of nest

gets rid of competition if resources are limited

89
Q

describe infanticide in languor monkeys

A

new male takes over troop and kills as many babies of previous males as he can to increase his reproductive success

90
Q

how much more likely are children with step parents to be abused in USA?

A

40X

91
Q

how do spotted hyenas communicate?

A

sound + gestures
erect tail= aggression
tail forward over back= excitement
tail between legs= fear

92
Q

what was Dawkins experiment?

A

cumulative selection

experiment demonstrating process driving evolutionary processes

93
Q

what is a -ve of of female pseudopenis in female hyenas?

A

difficult to mate and give birth from it

94
Q

why may the pseudopenis have evolved in female hyenas?

A

high levels of male sex hormones to allow for killing siblings and larger females

95
Q

what are the sensory modalities in:

a) ravens
b) blue tit
c) luna moth
d) chimps

A

a) vocal
b) UV
c) olfactory
d) tactile

96
Q

what is sensory exploitation?

A

biasing effect of existing perceptual mechanisms on origins of new communication signals

97
Q

how do you test for sensory exploitation?

A

present novel signals to to species that have never experienced them before, if they respond more to signal than control then evidence for sensory exploitation

98
Q

what did nick Davies find about begging intensity for cuckoo chick and reed warbler host?

A

begging intensity of one cuckoo chick similar to entire brood of reed warbler chicks
(high begging intensity means high feeding rate)

99
Q

what is signal size a compromise between?

A

costs and benefits

100
Q

what is the female waist:hip ratio correlated with?

A

corrected with woman long term health and reproductive endocrinological status, low ratio indicates high reproductive capability

101
Q

what 2 things do you need info on for understanding evolution of communication systems?

A
  • origins of signal and changes taking place

- causal processes causing changes

102
Q

whats the max human lifetime reproductive success for males and female?

A 
male= 888 children
female= 69
103
Q

whats the operational sex ratio?

A

ratio of sexually active males to fertile females

104
Q

describe Robert trivers idea of parental investment ?

A

relative amount of investment by each sex

  • assumed individuals have finite amount of resource to invest
  • determines how much competition and choosiness there is in a particular species
105
Q

what are the 3 varying levels of male PI?

A
  1. females invest more (male plumage more elaborate)
  2. male and female invest similarly (rear offspring)
  3. males invest more (females bigger + brighter)
106
Q

what does sexual selection drive?

A

morphological and behavioural traits

107
Q

what are the 2 types of post copulatory sexual selection?

A
  • sperm competition

- cryptic choice

108
Q

what is an adaptation for sperm competition?

A

large testes size produce more sperm

109
Q

in primates when looking at residual testes size what does it mean for testes size of above or below line?

A

above: relatively large testes
below: relatively small testes

110
Q

why do gorillas have small testes?

A

there is an alpha male that females are faithful to and so sexual selection occurs before copulation
