Q

What is the conundrum of Umwelt?

A

Each organism have a different umwelt therefore it is difficult to determine how an organism may perceive the world. (their perspective is difficult to see).

Q

What is sensory ecology?

A
  1. Based on studying of sensory system of an animal.
  2. To understand how organisms percieve their environment.
  3. How would thier perception affect their interactions with the environment.

Q

What is perception dependent on?

(2 things)

A

Perception depends on two things:
1. The individual senses that the organisms possess
2. The internal working of the organism’s nervous system at any given time.

Q

What allows us to gain a new perception on the world ?

A

The use of technology that enables us to see above and below our spectrum of senses that we lack the sense organs for. And so this aids in understanding the animal behavior.

Q

What organims uses infrared wavelenghts?

A

A snake.

21
Q

How does the snake use infrared spectrum to capture prey?

A

They haunt mamals and birds that always appear warm in their environment. So they have IR pits on their heads that have IR sensative receptors. this allows them to hide in sucluded places and wait on an IR emitting prey tp stray by.

22
Q

What animals uses UltraViolet?

A

Bees, birds, butterflies.

23
Q

Describe how bees use ultraviolet radiation?

A

They see the flower as a blue-black colors, and so the dark area will guide them directly to the nector of the flower.

24
Q

Compare honeybees, Humans, and hummingbirds visuals.

A
  • Honeybees- have trichromacy (3 color cones) that are sensitive to different wavelgnth in each band.
  • Meanwhile, although humans have a trichromacy they are sensitive to lower wavelenghts than honeybees (peak sensitivity is lower).
  • Hummingbirds: Are tetrachromacy (3 cones and a bee beat). Peak sensitivity is higher than humans and honeybees.
25
Q

What kind of eyes to Mantis shrimp has?

A

Compound eyes.

26
Q

What does compound eyes of mantis shrimp has?

A

Tiny repeating units of Ommatidia.

27
Q

Ommatidia is covered by its own cornea and functions as a singlle visual receptor.

(true or false)

A

True

28
Q

Together ommetidia send a mosaic image.

(true of false)

A

True

29
Q

The more ommatidia that better the image

(True or false)

A

True

30
Q

Where are the receptors (12 to 16) located in the Shrimp?

(mid what)

A

Midband

31
Q

How many receptors are present in a rock shrimp?

A

6 receptors

32
Q

How many opsin do the 6 receptors have?

A

They have 2 opsin

33
Q

What is opsin ?

A

A light sensitivity protein

34
Q

What is the limitation and advantage to the eyes of the shrimp?

A
  • They cannot detect similarity variations in colors.
  • However they have exceptional sight. But their ability to perceive is limited by their tiny crustacean brains.
35
Q

What is refered to the sense of hearing?

(define)

A

The ability to detect sound through a medium such as air, or water.

36
Q

A mantis have 3 focal points and can see in the IR and UV spectrum.

(True or false)

A

True

37
Q

Where do Mantis store their energy?

A

In their club.

38
Q

What does vibrations do when it reaches the ear?

A

It causes ear structures to vibrate and creates an electrical signal that connects to the brain. The brain interprets the nerve signals as sounds.

39
Q

Anything above the hearing of Human capacity, cannot be heard.

(true or false)

A

True

40
Q

How do we measure sound?

(measurement)

A

frequency

41
Q

Which type of sound travels long distances?

A

Low frequencies so that is infrasound.

42
Q

What animals uses infrasound and for what purpose?

A

To communicate and elephants uses this sound frequency.

43
Q

How many hz is the infrared sound?

A

10hz

44
Q

High frequencies travel long distances in air and below ground.

(True of false)

A

False

45
Q

What is the frequecny of Ultrasound?

A

10,000 to 200,000 Hz

46
Q

What animals uses Ultrasound?

A

Bats, frogs and insects.

47
Q

What is Ultrasound used for in animals?

(3 things)

A
  1. Avoidance of predators
  2. Communication
  3. echolocation.
48
Q

What happens in Ultrasound in bats?

A

When bats emitt ultrasound wavelenghts, it is usually reflected off solid objects such as insects. Which allows bat to locate their food.
