40
Q

What is a FAP

A

a sequence of unlearned acts directly linked to a simple stimulus. They are usually unchangeable and once initiated are carried to completion.

41
Q

What is sign stimulus?

A

it is the trigger for behavior and an external cue

42
Q

How do animals migrate?

A

They use environmental cues to guide them. Some of these cues include tracking their position relative to the sun’s position, adjusting with the circadian clock (internal mechanism), and sensing the magnetic field.

43
Q

What is a circadian rhythm?

A

This is a big role in animals daily activities. It is normally synchronized with light and dark cycles.

44
Q

What is a circannual rhythm?

A

These reflect longer behaviors and is a longer cycle, usually a year. Still influenced by daylight and darkness and lunar cycle with tides.
Ex: crabs link reproduction to times of greatest tide movement.

A

lifestyle and environment of the animal

46
Q

Most terrestrial animals use what two forms of communication?

A

Olfactory and auditory

47
Q

Most birds and humans use what two forms of communication?

A

Visual and auditory

48
Q

Animals that communicate through odors and tastes emit what chemical substance?

A

Pheromones

49
Q

Pheromones are common in…

A

insects and mammals related to reproductive behavior

50
Q

Pheromones can serve as _______ signals and can travel _____ distances.

A

alarm
long

51
Q

Learning is

A

a modification of behavior because of a result of specific experiences. Involves the formation of memories.

52
Q

When does imprinting occur?

A

During a specific time of development called the sensitive period. This is a time when young imprint on parent and learn basic behaviors while parents learn to recognize offspring.

53
Q

What is spatial learning?

A

the establishment of a memory that reflects environments spatial structure.

54
Q

What is associative learning?

A

The ability to associate an environmental feature (like color) with another (foul taste).

55
Q

Associate learning paired with a reward or punishment is?

A

Operant conditioning or trial and error learning

56
Q

Do all animals have associate learning?

A

Not all animals. Some can’t learn to make particular associations that seem logical.

57
Q

The most complex forms of learning involve?

A

Cognition

58
Q

What is cognition?

A

the process of knowing that involves awareness, reasoning, recognition, and judgement.

59
Q

Information processing of a nervous system can be revealed in ______ _______?

A

problem solving

60
Q

Problem solving is….

A

cognitive activity of devising a method to proceed from one condition to another in the face of real obstacles.

61
Q

What is social learning?

A

Learning through observing and interpreting behaviors and their consequences.

62
Q

What does social learning forms the roots of?

A

Culture

63
Q

What is culture?

A

A system of information transfer through social learning or teaching that influences the behavior of individuals in a population.

64
Q

What is fitness?

A

An organisms’ ability to survive and reproduce.
Reproductive success

65
Q

What is foraging?

A

food obtaining, eating, any activities the animal uses to search, recognize, and capture food.

66
Q

What is the optimal foraging model?

A

A natural selection that should favor foraging behavior that minimizes the costs of foraging and maximizes benefits.
Benefits of nutrition vs. cost

67
Q

What are some ways prey forage?

A

In groups, cost of vigilance is higher (more eyes), and they use alarm calls.

68
Q

Mating behaviors and success determine…

A

Reproductive success

69
Q

Characteristics of a monogamous relationship…

A

Both sexes look alike, pair bonds only during breeding season, mostly birds, extra-pair bonds= cheating

70
Q

Characteristics of polygamous relationship…

A

the sex that attracts multiple mating partners are typically showier and larger than the opposite sex.

71
Q

What are the two types of a polygamous relationship?

A

Polygynous
Polyandrous

72
Q

What is a polygynous relationship?

A

1 male, many females; Males larger are showier

73
Q

What is a polyandrous relationship?

A

1 female, many males: females are larger and showier

74
Q

T/F the needs of a young can constrain the evolution of mating systems?

A

True

75
Q

A situation where young birds can fend and take care of themselves (independent from parents) often implies….

A

That males will maximize fitness with polygynous relationship

76
Q

What is certainty of paternity?

A

When the female (males) is certain the eggs laid are hers

77
Q

Certainty of paternity is higher with what type of fertilization?

A

External because the egg laying and mating occur at the same time as opposed to internal fertilization which has a higher time between fertilization and egg laying.

78
Q

What is sexual selection? and what does it often result in?

A

Choosing a mate and the process of getting that mate. It often results in sexual dimorphism.

79
Q

How do females choose their mates?

A

They look for the physically healthy and attractive males because this ensures their offspring will have a high fitness level. Ex: males that are attractive to other females= good mate. Ex: mates that resemble their father.

80
Q

How to males choose their mates?

A

They often compete for their mate with other males. Often results in reduced variation among males.

81
Q

What is the game theory?

A

It evaluates alternative strategies in situations where outcome depends on strategies of all individuals involved.
Ex: rock, paper, scissors of lizards

82
Q

What is the difference between “home range” and “territory”?

A

Home range: area normally transversed during daily activities
Territory: portion of home range that is protected exclusively by aggression and advertisement.

83
Q

What is the antidiuretic hormone (ADH) or vasopressin?

A

A peptide released during mating, and it binds to specific receptor in CNS.

84
Q

When behavioral variation between populations of species correlates with variation in the environment this is due to…

A

natural selection

85
Q

What is inclusive fitness?

A

The total effect an individual has on proliferating its genes by producing its own offspring and by providing aid that enables other close relatives to produce offspring.

86
Q

The exchange of aid between non-relatives is?

A

Reciprocal altruism

87
Q

What is sociobiology?

A

certain behavioral characteristics exist because they are expressions of genes perpetuated by natural selection.

88
Q

What is classical conditioning?

A

stimulation associated with a reward or punishment

89
Q

What is operant conditioning?

A

behavior associated with a reward or punishment
