eating and avoid being eaten Flashcards
what are two behavioural problems when recognising food
1) recognising food
2) catching food
- need to be able to tell edible from inedible
dependant also on preference such as generalist vs specialist
what is a search image
when individuals encounter prey animals they develop more detailed image with the experience, therefore foraging becomes more successfull
this requires learning
what are two forms of defensive behaviour
1) avoiding detection
2) escape adaptations
what are three ways of avoiding detection
1) blending in
2) being quiet
3) choosing a safe place
what is crypsis
the ability of an animal to avoid observation or detection by other animals as a way of blending in
colouration is not enough, individuals also need to behave/orientate themselves
what is meant by masquerade and mimesis
when individuals mimic inedible objects
what are some ways of escaping predators
1) fleeing
2) inspection
3) faking death
4) predator signalling
5) attack
what is flight initiation distance
the distance a predator needs to be before prey flee
- distracted animals initiate slower
what is the difference between batesian mimicry and mullerian mimicry
1) when tasty prey mimic a poisons prey
2) when all mimicking species are poisonous
