Question 4

Suppose a bushfire results in the loss of all individuals in species D. Would this impact the classification of the ecosystem? Explain your answer. (2 marks)

Data Set 7

An Australian wildlife research organisation is attempting to gather some data about the abundance of marsupials after a catastrophic bushfire. They undertake surveys in 3 separate locations that have each been impacted by fires. At the first location, they set out to estimate the population of koala —Phascolarctos cinereus.

第一个样品由44个Koalas组成,每个样品被标记并释放到野外。研究人员在几天后返回,收集由预先标记的20个Koalas - 7组成的第二个样本。

Question 1

使用林肯指数在此地点估算考拉的人口大小。(2分)

Data Set 8

The following data was collected by the Australian wildlife research organisation:

Question 1

Calculate the SDI for each of the three locations. (6 marks)

Question 2

In which of the 3 locations, is a researcher likely to see the same species twice in a row? Why? (2 marks)

Question 3

Calculate the relative frequency ofM. giganteus在三个位置中的每一个。(6分)

Question 4

如果您要从每个地点拍摄10个生物,那么您有最大的机会看到一个位置V. ursinus在样品中?(3分)

Data Set 9

Question 1

What type of curve has been used to model the population growth of Species 5? (1 mark)

Question 2

基于the graph, what is the carrying capacity? (1 mark)
