Birds, Parasites and Economics Adult Red grouse are medium to large-sized “gamebirds” feeding on shoots, buds and seeds of small shrubs and herbs, found on the heather moorlands of Scotland. A healthy Red grouse population generates an estimated £23·3 million per annum for the Scottish rural economy. Grouse shooting supports over 1000 full-time equivalent jobs. Red grouse populations in Scotland show “cyclic fluctuations” with the major downturns being caused by a parasitic worm. This worm causes damage and internal bleeding after burrowing into the intestine of the Red grouse. These parasites can cause a mortality rate of 78% in the Red grouse population. Crashes in grouse numbers following parasite infestations can reduce income substantially on many upland estates. Over the last 15 years, medicated grit has been used to reduce the number of worms in Red grouse. The active drug in medicated grit is fenbendazole, which kills the eggs and larvae of worms as well as the worms themselves. It reduces the number of worms in Red grouse by about 40%, and improves grouse breeding success by increasing chick survival. (a) (i) Name the type of feeding behaviour found in adult Red grouse. 1 (ii) Give the habitat of the Red grouse. 1 (b) What is the relationship between the size of the Red grouse population and the rural economy? 1 (c) (i) What is meant by the term “parasite”? 1 (ii) A Red grouse population of 5600 was infected with parasites causing a mortality of 78%. Calculate the number of birds remaining in this population. Space for calculation 1 [X055/11/01] Page twelve DO NOT WRITE IN THIS MARGIN Marks 4. (continued) (d) Explain why the use of fenbendazole can improve Red grouse breeding success. 1 (e) Explain how the use of pesticides can reduce biodiversity.
