sampling

Question 1

How to sample an immobile species?

Answer 1

= random quadratting

Question 2

How to sample a mobile species?

Answer 2

= systematic sampling

Question 3

how to sample a moving species?

Answer 3

= mark release reacapture

Question 4

What is random quadratting?

Answer 4

= place 2 measuring tapes at right angles- x and y axis and apply random coordinates and place a quadranr in this region
= abundance is estimated using this quadrant
= repeat many times for reliable results- until running mean is similar
= calculate avaerga enumber of irgansims per quadrant area
= times by the area of the region being ivestigated to estimate population suze

Question 5

What is systematic sampling?

Answer 5

= position transect across area randomly
= decide an appropriate interval
= abundance estimated using a quadrant
= repeat to get reliabke results
= until running mean is similar

Question 6

What is mark capture release?

Answer 6

= capture species first
= make the species so they do not get repeated
= species are released to redirtubiute
= captyure second sample and record how many total and how many marked
