A survey was conducted to estimate the population of barnacles (figure 1) in two coastal areas (i.e. A and B). The dimension of coastal area ‘A’ is around 20 m and 26 m. The dimension of coastal area ‘B’ is around 14 m and 15 m

Sampling in both areas was conducted using 1 x 1 m quadrat. Six quadrats were sampled randomly in each area. The numbers of barnacles in each quadrat as the following.
Area Q1 Q2 Q3 Q4 Q5 Q6

A 2 1 3 1 4 2

B 12 11 5 3 6 2


1. Calculate the estimated population of barnacles in both areas A and B. Please show the details of calculations. [5]

2. Discuss your findings. [5]

Based on the data provided;

  • Estimated population of Barnacles in A is 1128 Barnacles
  • Estimated population of Barnacles in A is 1365 Barnacles
  • the population density of Barnacles in B is greater than that in A.

What is a population density?

Population density is the number of organisms per unit area of a given geographical area or location.

Population density gives an idea of how densely or sparsely populated a given area is.

  • Population density = number of organisms/area of land.

The area of quadrant = 1 m × 1 m = 1 m^2

Total number of Barnacles in 6 quadrant sample A = 13

Average = 2.17

Population density = 2.17/1m^2 = 2.17 /m^2

Total number of Barnacles in 6 quadrant sample B = 39

Average = 6.5

Population density = 6.5/1m^2 = 6.5 /m^2

Area of A = 20 m × 26 m = 520 m^2

Estimated population of A = 520 m^2 × 2.17 /m^2

Estimated population of Barnacles in A = 1128 Barnacles

Area of B = 14 m × 15 m = 210 m^2

Estimated population of Barnacles in B = 210 m^2 × 6.5 /m^2

Estimated population of Barnacles in B = 1365 Barnacles

From the above results, the population density of Barnacles in B is greater than that in A.
