BIOS – 272 Exam Questions and
Answers
a behaviour/attribute by one animal that causes a change in another animal: - Correct
Answers -signal
communication can be: - Correct Answers -chemical, auditory, visual, tactile
Tungarau frogs: - Correct Answers -exploit female pre-existing bias for a specific
frequency (chuck as close to that frequency as possible) to gain mates
signal detection theory: - Correct Answers -maximise hits, minimise misses
handicap principal: - Correct Answers -signals are only honest if they are costly to
maintain and produce e.g. Velvet monkeys (warning signals)
sea turtles making the trip from Atlantic ocean to coast of florida use what mechanism of
migration: - Correct Answers -earth magnetic field incineration (not polarity direction)
2 types of magneto-receptors: - Correct Answers --specialised photoreceptors (light
sensitive) (amount of light absorbed provides information about local magnetic field)
-magnetite (Grey whales have large amounts in their retina)
when both the sender and receiver have the same interest in the result: - Correct
Answers -hones signal/communication
when one animal exploits another to increase its own fitness: - Correct Answers -deciet
result of stimuli, sensory processing, motor control, cps control, hormonal control: refers
to: - Correct Answers -dynamic control (T Q 1)
Death adder lure: - Correct Answers -exploits pre-exisitng biases of Jacky dragons
motion detection by mimicking the speeds most common of its prey in its environment
conspicuous appearance advertises poisonous/unpleasantness: - Correct Answers -
aposematism
models an animal with aposematism: - Correct Answers -Batesian mimicry
Arizona mountain snake vs. Arizona coral snake: - Correct Answers -harmless
(batesian) vs. poisonous (aposematism)
, Dynamic batesiam mimicry: - Correct Answers -mimic octopus, mimics lots of different
sea creatures (versatile)
chemical defences (distasteful/toxic): - Correct Answers -e.g. Golden Dart frog, most
poisonous animal in the world, enough poison in 1 frog to kill 200 people
mechanical defences: - Correct Answers -e.g. Porcupine has sharp quills
camouflage/crypsis defence: - Correct Answers -coloration/body type/behaviour that
makes the animal hard to perceive
Background matching defence: - Correct Answers -animal blends to background which
it rests (e.g. seahorse mimics corals in colour and shape)
disruptive coloration defence: - Correct Answers -disrupts outline of an organisms body
masquerade: - Correct Answers -e.g. stick insect mimics stick (deemed inedible)
eye spot defence: - Correct Answers -deflects attack, located on non-vital body part,
can be used to startle predator (e.g. butterflies)
autotomy defense: - Correct Answers -diverts attention (e.g. lizard looses tail, spider
looses leg) often body part can grow back
Feigning injury/death defence: - Correct Answers -e.g. ducks, use to divert predator
attention away from nest
vigilance defence: - Correct Answers -e.g. meer-cats communicates to predator that
prey is alert
Stotting defence: - Correct Answers -communicates to predator that its been spotted
and can be outrun e.g. Giselle
Mobbing defence: - Correct Answers -e.g. Gulls, harasses and discourages predator
squirrel defences against rattlesnakes: - Correct Answers --mobbing
-infra-red tail flagging
-SSA
-ultrasonic calls (increases vigilance in conspecifics)
what sequesters poison form trees: - Correct Answers -afrcan crested rat
types of neurone: - Correct Answers -sensory (sensory receptors - cns)
motor (cns - glands/muscles)
interneurons (connections between efferent and afferent)
