B7- Sampling

Question 1

what is the 6 step method for sampling?

Answer 1

1-lay (20) by (20)Metres tape measures out at a right angle to create a grid = Total area that you are sampling (400m2)
2- randomly pick coordinates (2 NUMBERS) using RANDOM NUMBER GENERATOR
3- place qudrat (0.5m x 0.5m) at the random coordinates (1st sample area (0.25m2))
4- COUNT all organisms of species that you’re sampling in the quadrat
5-repeat steps 2-4 for AT LEAST 10 QUADRATS
6- calculate mean number of organisms per quadrat

Question 2

what are 2 equations for estimated population size?

Answer 2

total area/ qudrat area x mean number of organisms

Question 3

what is sampling?

Answer 3

to study the distribution of an organism & estimate the size

Question 4

what is sampling along a transect line (how different)

Answer 4

investigating the effect of a factor, place a quadrat along a line (NOT RANDOM)
