1. To assess the importance of studying
animal behavior in ethology.
2. To analyze the factors which affect
animal behavior.
3. To describe the importance animal
behavior research has on human
psychology and social sciences.
2
• Examines the reaction of an animal to
a certain stimulus
• Shows how an animal reacts with its
environment
• Reflects internal and external factors
as well as learned activities
Stimulus – an agent, action or condition
which causes a response
3
• Is the study of animal behavior, especially in
the natural environment
• Examines instinctive and adaptive nature in
early development
• Observes natural processes such as
communication, courtship, mating and self
defense
• Monitors animal welfare influenced by
internal, external and learned factors
Welfare – the health, happiness and well-being
of an animal
4
• Study the science of heredity and variation
of inherited traits among related organisms
• Explain instincts, which animals are born
with
• Control some behavior, such as walking,
which is shared by most animals whereas
other actions are unique to certain animals
Instincts – inborn pattern of behavior which is
characteristic of a species, often a response to
their environment
5
• Causes a newborn kangaroo to crawl
into the mother’s pouch and begin
nursing
• Tells a newly hatched herring gull to
peck a small red spot on its mother’s
beak in order to be fed
• Allows a spider to build a perfect web
for the first time despite having no
previous experience with webs
6
• Are chemicals secreted by an animal which
influence the behavior of others in the same
species
• Include the following:
– aggregation
– alarm
– epideictic
– territorial
– trail
– sex
7
• Promote the cohesion of animals
• Attract both male and female animals
• Influence animals to form groups for
protection, migration and mating
Example:
Spiny lobsters use aggregation
pheromones to create safety in numbers
by forming groups to wave their spiny
antennae in order to deter predators
Cohesion – the act of uniting or sticking together
8
• Warn animals of possible predators
• Trigger defensive and aggressive
behavior
• Emitted by one animal in a group will
cause others to respond
Example:
Alarm pheromones excreted from the
stinger of a worker bee signals other bees to
the threat, explaining why once one bee has
stung, others move in
9
• Are known as spacing pheromones
• Regulate population density
• Affect the colonization or extent of
exploration of a plant resource
• Helps parasites identify healthy hosts
from parasitized ones
Example:
Flies will produce epideictic pheromones
when laying eggs to deter other female flies
from laying larvae in the same spot
10
• Define the claimed area of specific
organisms
• Warn other animals of nearby
dominant animal
• Can be used to recognize other
animals, such as an ant from another
colony
Example:
Dogs deposit territorial pheromones,
present in their urine, on landmarks to
mark the boundaries of their terrain
11
• Allow animals to follow one another
• Lead to food sources, new colonies
and prey animals later plan to kill
• Permit lost animals to find their way
back to the group by following their
scent
Example:
When found walking in a straight line, ants are
actually following the trail pheromones left behind the
ant in front of them rather than the ant itself
12
• Attract the opposite sex in animals
• Allow animals to know when the
opposite sex is ready to mate
• Used by predators can trick prey into
being caught
Example:
When a female dog is in heat, she is
excreting sexual pheromones which can
attract male dogs over a mile away
13
• Are chemical substances in the body
which regulate or control specific
physiological processes
• Include the following:
– epinephrine
– estrogen
– testosterone
14
• Releases in response to physical or mental
stress such as fear or injury
• Accelerates heart rate and raises blood
pressure
• Is released during a fight, resulting in
animals being aggressive for several hours
after
Example:
When dogs fight one another or feel threatened, high levels
of epinephrine are released which cause them to become
hostile to both the aggressor and surrounding animals,
including humans
15
• Induces estrus and prepares the uterus for
reception of a fertilized egg
• Causes females to be receptive to males for
mating
• Attracts males from up to a mile away
Example:
When housecats are in estrus due to the release of
estrogen, it is known as being in heat and their
behavior becomes more agitated, loudly meowing
16
and rubbing on everything
• Stimulates the development of the male sex organs
and sperm
• Leads to a hierarchy in most animals, the dominant
male having the highest level of testosterone
• Causes males to seek females for mating and
accounts for their aggressive behavior toward other
males during this time
Example:
When two male dogs are seeking the same female,
the dog with a higher level of testosterone will
17
succeed in obtaining the female
• Inhibits activity among females, decreasing the
amount of time spent walking or standing and
increasing the amount of time spent sleeping
• Increases the amount of food a female will
consume
• Causes females to become more agitated and
aggressive towards other animals and humans
Fun Fact:
The Asian Elephant’s
pregnancy lasts for 22
months
18
• Describes an environment which supports
the survival of cells inside an organism
• Is achieved by all body systems working
together to maintain body temperature,
acidity and oxygen levels
• Occurs at different levels in different animals
• Operates both internally and externally
Example:
A dog will curl into a ball and use its
tail to cover its nose to minimize heat
loss during cold weather
19
• Include the following:
– environment
– communication
– courtship rituals
– threats to safety
20
• Includes the surroundings, influences
and conditions placed upon an
organism
• Influences how an animal feeds and
reproduces
• Shapes how animals will respond to
new situations, including the
introduction of humans
21
• Live independently of humans
• Set up territories in areas with plenty of
food sources, water and shelter
• Fight to establish dominance
• Scavenge for food
• Find their own breeding partners
22
• Rely on humans for housing and
feeding
• Breeding is largely controlled by
humans
• Learn to obey their owners
Fun Fact:
Domestic turkeys
weigh twice as much
as wild turkeys
23
• Can be broken up into the following three
groups:
– tamed wild animals: breed on their own
while maintaining loose ties with humans
– semi-domesticated animals: breed on their
own but have undergone physiological or
behavioral changes due to captivity
– domesticated animals: completely rely on
humans for breeding and feeding purposes
Physiology – biological study of the functions
and activities of living organisms and their parts
24
• In animals is classified and described
based on the way in which animals
receive the signal, including the
following:
– chemoreception
– mechanoreception
– visual
– vocal
25
• Describes the physiological response to a
chemical stimulus
• Includes recognizing and exhibiting
pheromones and identifying substances
based on taste
• Explains behavior in animals such as
constant licking and sniffing
Example:
Butterflies have chemoreceptors on
their feet to let them sense different
strengths and types of nectar
26
• Expresses an animal’s response to a
physical stimulus
• Includes communicating through vibrations
including the following:
– substratum: through the ground or other
foundation
– acoustic: through the air or water
Example:
Spiders use vibrations to pluck mating calls to
one another as well as determine the type and
location of prey that have landed on the web
27
• Led to competition among males for the most
impressive displays to attract females
• Wards off other male competitors
• Is displayed through facial expressions and
body language is commonly used by
chimpanzees
• Alerts predators to the position of their prey
Example:
Male peacocks’ brightly colored tails are used to
impress and attract female peacocks, but also
28
attract predators
• Is made by the giving and receiving of
audible noises from one animal to
another
• In dolphins and whales include making
clicks and squeals to inform others of
feeding, migration and location
• In elephants involve emitting a low
pitched sound below the level of human
hearing which draws in other elephants
from miles away
29
• Attract members of the opposite sex for
mating
• Include jumping, dancing, singing and
displaying decorations
• Cause males to become more territorial and
aggressive, often leading to a fight with rival
suitors
Fun Fact:
Male grasshoppers can produce over
400 mating songs and each has a
different meaning
30
• Occur when predators attack,
unknown creatures appear or animals
feel trapped
• Cause animals to become tense and
aggressive
• Result in a fight or flight situation
31
• Include the following:
– habituation
– conditioning
– reasoning
– imprinting
32
• Occurs when an animal becomes accustomed to a
particular situation due to frequent repetition
• Results from exposure to an event which merits no
reward or punishment
• Leads to an animal completely ignoring the event to
which it has become accustomed or see no danger
in it, as with deer becoming habituated with passing
cars
• Allowed Jane Goodall to study chimpanzees after
they became habituated with her
Jane Goodall – zoologist who studied the chimpanzee
33
and gained knowledge of primate behavior
• Happens when animals learn to respond to a
stimulus in a certain way due to reinforcement
from a reward or punishment
• Occurs in the following forms:
– conditional: pairs a neutral stimulus with
one that elicits a response until the neutral
stimulus itself causes the response
– operant: causes an animal to associate a
certain behavior with pain or pleasure to
either reinforce or discourage this behavior
34
• Involves an animal responding
correctly to a stimulus the first time it is
presented
• Takes place when an animal uses past
experiences to make a decision
regarding its actions
35
• Is rapid learning which occurs during a
brief receptive period, often right after
birth or hatching
• Is irreversible
• In geese occurs after the hatching of a
gosling, which is pre-programmed to
identify the first thing to emit a goose
call as its mother and follow it should it
wander off
36
• Is studied to help understand human behavior,
instincts and social interactions
• Is paired against human behavior in comparative
psychology to analyze a specific action and see if the
two share similarities
• Is researched in evolutionary psychology to see how
humans and animals have adapted to living in their
environments over the years
• Helps scientists study sociobiology, which examines
social behaviors in animals and humans and shows
the evolutionary advantages of such behaviors
