Q

What are the four basic concepts of the sensitive period?

A
  • Fairly Extended.
  • Gradual onset and termination.

Q

What is a major difference between critical period and sensitive period in regards to learning new behavior?

A

Critical period behaviors are only learned during that time, afterwards the brain is rewired.
In sensitive periods the behavior is learned at an accelerated pace, Vs after- still possible but slower. Think language learning as toddler Vs adult.
Sensitive period behaviors can also be modified after learning them unlike critical period. These sensitive behaviors are more resilient when decreased.

Q

What are two factors regarding when a sensitive period will be induced?

A

When the internal and external factors align. EX: Olfactory neuron set-up (internal) and (external) scent in the environment- that scent will likely be remembered and set a behavior. Salmon will imprint the scent of their natal stream to return to for mating.

Q

What are two ways of determining the end of a sensitive period?

A
  • The learned behavior changes neuro and is self-terminating.
  • Maturation leads to the body being less receptive to what triggered the sensitive period.

Q

How does entrainment of a biological clock become beneficial?

A

This is beneficial because when the exogenic factors of entrainment change the endogenic ones adapt to it. EX: During the winter the days are shorter, are bodies adjust to feel tired at a different time as we conduct activities at different times.

Q

Birds migrate yearly frequently for food more abundant in other places. They bird arguably don’t know the time of year or the “why” they do this. Why does this occur?

A

This occurs due to an infradian circannual biological clock that has evolved due to the advantage of flying south for the winter ensure a better chance of survival Vs. staying.

Q

What cell bodies are within the hypothalamus?

A

Suprachiasmatic Nuclei.
When grown in a petridish these cells exhibited their own rhythmic electrical activity even without any exogenic stimuli.
These cells can exhibit control over other body clocks through the release of hormones such as cortisol.
(Assumed to be true of all mammals/ amniotes. Worth noting head does not play this role in drosophila clocks.)

Q

Exogenic stimuli affects entrainment, what is this pathway for something such as light dark cycle in vertebrates?

A

In Vertebrates our retinas contain specialized photoreceptors within the related ganglion that send a direct signal to the suprachiasmatic neurons in the hypothalamus and lead to a change in the production of the hormone melatonin- this is the process of entrainment. The more light exposure, the more melatonin produced.

how do sharks and rays use the ampullae of lorenzini?

A

This allows them to sense electric potential at different points in the magnetic field, so they can sense nearby prey and predators.

60
Q

63
Q

What are the three costs of natal philopatry?

A
  • Increased competition
  • Inbreeding
  • Mating suppression (usually done by adult breeders.)
65
Q

Two benefits of natal philopatry?

A

Staying “at home” means you are likely already in an environment you are adapted for.
Familiarity in finding resources and avoiding predators.

66
Q

When offspring leave their birth area to live elsewhere.

A

Natal Dispersal.
Costs: Must be capable of making the journey.
Unfamiliar territory
Benefits: Avoids inbreeding
New resources and usually less competition

67
Q

What gender typically disperses in aves?

A

The females.
This is because males in birds are usually defending resources and their offspring survival heavily relies on monogamy usually.

68
Q

What are the four factors affecting sex bias dispersal?

A
  • Inbreeding Avoidance
  • Local Resource competition
  • Local Mate competition
  • Kin cooperation.
69
Q

Explain why male lions are territorial, yet disperse?

A

They do not have great kin cooperation. The male lion which holds the natal territory will keep that the territory, but the other male lions have a better chance at reproductive success by leaving, as female do not go around looking for territory. Male are competing directly for females in lions, not admirable territory. Females also do most of the work in lions, so offspring has better chance of survival if females do not disperse.

70
Q

What gender typically disperses in mammals?

A

Males- this is due to different reproductive strategies and possibly poor kin cooperation. If the father is known to stay present at the home however, this may not be true to avoid inbreeding.

71
Q

What are three phases of finding anew habitat post dispersal?

A
  • Search.
  • Settlement.
  • Residency.
72
Q

A

Public information.

73
Q

What are the two tactics of looking for a new habitat?

A

The comparison tactic: Visiting multiple areas and picking a fave.
The sequential search tactic: Coming to an area, yay or nay- if nay they do not return if the next option is worse, they will keep moving till they find a yay.

74
Q

The influence that the natal habitat has on finding a new habitat?

A

Natal Habitat preference induction.
Usually advantageous as the natal habitat worked well for the parents it will probably suit the offspring.

75
Q

What are the requirements of a “migration”

A

Movement of animals should be annual/ seasonal or a major part of the animals life cycle (think salmon.)

  • Group work to create aggregations of prey.
  • Being able to capture prey the could be dangerous/ difficult.
100
Q

What is one cost group foraging?

A

Two types of competition between group members.
Scramble competition: Shared resource competition. Thinks sharks which herded a school of fish.
Interference competition: Presence of competitors prevents forager access to resources- Think dolphins stealing from stingray.

108
Q

Type of camouflage with movement not used to hide from predators?

A

Motion camouflage. Think dragonfly approaching its prey at a certain angle which makes it appear to not be moving so it is not perceived as a threat.

109
Q

Coloration of animal which breaks up its body line using bright colors/ shapes and harder to detect.

A

Disruptive Coloration. Think jaguars/ tigers. They don’t exactly blend in, but their coloration/ pattern makes them harder to spot.

A

Mullerian Mimicry.

114
Q

A

Autotomy.

116
Q

Strategy of making a non-vulnerably part of the body look like a vulnerable one to avoid being attack vulnerably.

A

“False-Head” Think butterfly species where its butt looks more like it’s head. if a predator attack there the butterfly can likely survive and escape.

117
Q

How does having a large spot on the end of a cichlid’s tail assist it?
What is this an example of?

A

This is an example of “false-head” This is defensive. Other fish like to nip at the cichlid’s tail and by thinking it’s tail is the head they will avoid it and go towards the face where the cichlid can defend itself.

Predator satiation.

123
Q

When prey in a herd are always trying to be in “center herd”

A

Selfish herd. This is because prey on the outer limit are more likely to be targeted.

A

Confusion effect
(GROUP)
