Complete Exam Questions and Answers

100% Solved | Graded A+


Draw predator-prey flow chart (behavioural options for prey) - ✔✔


Prey survivorship curve? - ✔✔


(Search) What are some methods animals avoid being found? - ✔✔-

Different time of activity from predator.

- reduced movement

- camouflage

- small size

(When detected) List lecture examples for predator-specific alarm calls (an

adaptation). - ✔✔Found in Prairie dogs, vervet monkeys, birds


(Detect) Types of visual warning displays that prey may exhibit to predators

+ examples. - ✔✔- California ground squirrels (kick sand into snake face.

,shows intense tail flicking in presence of rattlesnakes but not to gopher

snakes. They emit IR radiation to rattlesnakes because they are gopher

snakes, rattlesnakes are more sensitive. Causes the snakes to change

their behaviour from predatory to defensive).

- Owl butterfly (fixed eyespot)

- Caterpillar snake mimic.

- Cats arching back

- Skunks

(Detect). High fitness displays (honest signals). Define honest signals and

give 4 examples. - ✔✔- Honest signal is used to show off the individuals

fitness levels.

- Tail flicking in moorhen. Demonstrates a sign of vigilance directed

towards ambushing predators.

- Tail flags and rump patches in deer.

- The poison dart frog gives an honest signal of its toxicity to warn off

predators.

,-Stotting in springbok. Shows that it is young, fit, and not worth chasing.

Significantly increases survival.


(Detect). Behaviour of approaching the predator does what? - ✔✔-

decreases risk of predations.

- gathers information

- warn others of danger.

- Usually seen in prey groups of high numbers.


Describe mobbing and cohesion/social grouping. - ✔✔- Mobbing is when

groups attack predators.

- cohesion/social grouping is beneficial to achieve a "dilution effect". They

will increase this behaviour sometimes after seeing a predator (seen in

minnows)

(Pursuit) 4 methods of defense of prey when they are being pursued by a

predator? Give examples. - ✔✔Speed and manoeuverability, Protean

responses (unpredictability of movement, zigzagging, spinning etc.),

aggregated responses (fish bundling up, using flash expansion etc),

sensory interference (tiger moths making unltrasonic clicks to deter bats)

, Post capture behavioural defences, give 5 types with examples. - ✔✔1.

Group defense- seen in carnivores, primates water buffalo (remember

youtube vid)

2. Faking death (thanatosis)- seens in insects, spiders, fish, reptiles

(hognosed snakes), birds, mammals (but only a few species)

3. Screaming. Investigated and varied responses, most results show its for

predator interference.

4. Autotomization- shed a limb or tail to distract predators. Very

energetically expensive, and usually a last resort. After animals do this they

have to stay close to shelter, take fewer risks, shift to tissue repair rather

than mating.

5. Unpalatability. Animals eating toxic foods or retaining them somehow to

taste bad. Recently shown in the african crested rat, present in birds.


An optimality model - ✔✔If one can measure the fitness costs and benefits

associated with four alternative behavioural phenotypes in a population,

then one can determine which trait confers the greatest net benefit on

individuals in that population. In this case, phenotype X is the adaptation-
