Q

What is an indicator species

A

An indicator species is an organism whose presence absence for abundance reflects a specific environmental condition

17
Q

What is Mark and we capture techniques for?

A

To estimate population were to be impractical to count every individual

18
Q

List five methods of marking organisms

A
Banding
Tagging
 painting
Surgical implantation
Hair clipping
19
Q

What does N stand for

A

Population

20
Q

What does M stand for

A

Number marked on first count

21
Q

What does C stand for

A

Number captured on second count

22
Q

What does R stand for

A

Recaptured organisms

23
Q

List three assumptions of the mark and we capture technique

A

No emigration /immigration
 all animals have an equal chance of being captured
Marked individuals mixed fully with the population

24
Q

What is the study of animal behaviour

A

Ethology

25
Q

What is anthropomorphism

A

Allocation of human characteristics to the behaviour of animals

26
Q

List three measurements we can take to try and quantify animal behaviour and explain what they mean

A

Latency is the time taken between stimulus and response

Duration is how long the behaviour occurs for

And frequency is how many times behaviour occurs in a certain time frame

27
Q

What is an ethogram

A

And I think Graham is a list of species specific behaviours to be observed and recorded in a study
