finding and hoarding food Flashcards
what does resource distribution control?
they home range of the species
types of ingestive behaviour
foraging = finding food
hoarding= saving food
feeding = consuming food
radial maze study for WM in rats and mice
rats have a random but accurate search wether as mice search sequentially
water maze study in rats
the skill is hippocampus dependent
mating systems evidence for home range
polygamous voles have larger home rages and better spatial abilities with a larger a hippocampal volume
food caching evidence for home range size
food storing birds (corvids) have better spatial abilities and larger a hippocampal volume
food caching in nutcracker and chickadee
nutcracker after 10 days had a 50% accuracy
chickadee, 2 hours after caching had an above chance accuracy
brood paratisim evidence
female cowbird have better spatial ability and hippocampal volume due to them leaving their eggs in other birds nests, they keep track of multiple nests
object permanence and piagets six stages
stage 4 recovery of hidden objects
stage 5 visible displacement
stage 6 invisible displacement
what animals have object permanence?
chimps are successful and rhesus monkeys and dogs are unsuccessful
animals and their ability to track displacements
bonobo and chimps are good at tracking displacements, however dogs are not very good
what is socio-ecology?
the study of ecological factors on the interaction between individuals and their social organisation of their group
sociality of apes and their fission-fusion …
fission-fusion is the time spent together
low = gorillas high = chimps and orangutans
time spent together correlates with evolution
what are circadian rhythms?
endogenous timing mechanisms that predict changes in the environment and synchronise behaviour accordingly
types of circadian rhythms …
tidal cycle (12.4 hours)
light-dark cycle (24 hours)
seasons
what the circadian rhythm effects …
behaviour, feeding and reproduction as well as physiological (body temp, heart rate)
what is interval timing?
determining which cue signals the shortest delay to reward
key feature is the short arbitrary durations
What species displays time matching?
hummingbirds, the visit the food resource at or close to the moment of its replenishment
episodic-like memory …
encoding and retrieving info about what, when and where an event took place
seen in birds that are able to choose between nuts or worms after a delay period
