The grey wolf, Canis lupus, is a large predator. In south-west Europe during the 20th century, hunting drove the grey wolf to the brink of extinction.
(a(i))[1]

State the genus for the grey wolf.

(a(ii))[3]

Suggest and explain what would happen to the biodiversity of south-west Europe if the grey wolf became extinct.

(b)[2]

Grey wolves may hold territories as large as $950\ \text{km}^2$. Grey wolves can move up to $1000\ \km$ when founding a new population. State reasons why mark-release-recapture is unsuitable for estimating the size of a grey wolf population.

(c(i))[1]

Complete Table 2.1 so that it shows the percentage change in the size of the Iberian grey wolf population from 1970 to 2012. Enter your answer in the table to the nearest whole number.

(c(ii))[3]

With reference to Fig. 2.2 and Table 2.1, describe how grey wolf populations in south-west Europe changed from 1970 to 2012.

(d(i))[1]

In parts of south-west Europe where grey wolf populations are present, farmers worry about the safety of livestock such as sheep. Suggest how governments can help farmers who are concerned about the safety of their livestock.

(d(ii))[3]

Suggest measures that could help protect wild grey wolf populations in south-west Europe.
