Q: A wildlife manager is using radio transmitters in neck collars. What proportion of body weight should a transmitter ideally be, according to best practices?

$$\frac{\text{Transmitter weight}}{\text{Body weight}} \u003c 0.05$$

Question 1

Which of the following is NOT one of the four general types of data that can be collected through wildlife marking?

Accepted Answer

Habitat preference

Question 2

A wildlife manager wants to track the movement patterns of deer over a large area. Which marking technique is most appropriate and why?

Accepted Answer

Neck collars, because they can include radio transmitters for precise movement data.

Question 3

Which marking method is most preferred by wildlife managers and why?

Accepted Answer

Natural marking, because it induces little to no stress and is inexpensive.

Question 4

What is a major disadvantage of using banding as a marking technique for marine species?

Accepted Answer

Bands can erode in marine environments, reducing their effectiveness.

Question 5

Which marking technique is LEAST preferred due to its potential impact on animal health and public perception?

Accepted Answer

Invasive marking, such as radioisotope insertion.

Question 6

A wildlife biologist is considering using Passive Integrated Transponders (PIT tags) for marking fish. Which of the following is a limitation of this method?

Accepted Answer

PIT tags can only be measured in proximity of the individual.

Question 7

Which of the following is a general consideration before marking wildlife?

Accepted Answer

Obtaining proper approvals, such as IACUC and state/federal permits.

Question 8

Which marking technique is most likely to be used for genetic sampling and reliable identification, but may raise ethical concerns?

Accepted Answer

Tissue removal, such as feather clipping or ear punching.

Question 9

Why are natural marking techniques largely unsuitable for avian species?

Accepted Answer

Most birds lack distinctive morphological features for individual identification.

Question 10

A wildlife manager is using radio transmitters in neck collars. What proportion of body weight should a transmitter ideally be, according to best practices?

Accepted Answer

$$\frac{	ext{Transmitter weight}}{	ext{Body weight}} \u003c 0.05$$

Question 11

Which marking technique allows for easy, short-term identification from long distances but may negatively affect survivability or reproductive success?

Accepted Answer

External color marking (dyes, paints, fluorescent pigments)

Question 12

Which marking method is highly persistent, can be applied through consumption or injection, and is often used in bait studies?

Accepted Answer

Internal markers, such as Rhodamine B

Question 13

What is a major advantage of using PIT tags for marking wildlife?

Accepted Answer

They are passive and do not require batteries.

Question 14

Which marking technique is most likely to be used for herpetofauna species for color-coded identification?

Accepted Answer

Visible Implant Elastomers (VIE)

Question 15

Which marking method is simple, reliable, and not subject to equipment failure, but may raise ethical concerns?

Accepted Answer

Tissue removal (feather clipping, ear punching)

Question 16

Which marking technique is most likely to alter the health or mortality of individuals if not done correctly?

Accepted Answer

Tissue removal

Question 17

Which marking method is highly standardized and allows for easy identification of individuals, but is mostly limited to avian species?

Accepted Answer

Banding

Question 18

Which marking technique is most likely to be used for tracking later development in younger individuals?

Accepted Answer

Passive Integrated Transponders (PIT tags)

Question 19

Which marking method is most likely to be used for wildlife with large movement patterns and can include radio transmitters?

Accepted Answer

Neck collars

Question 20

Which marking technique is inexpensive, induces little to no stress, and is relatively easy, but is subject to user error?

Accepted Answer

Natural marking
