Ecology 6th Edition by Charles Krebs

تمرين 7

One of the controversies in disease ecology is whether the parasitic nematode Trichostrongylus tenuis has a strong effect on red grouse populations in Scotland and northern England. Review this controversy and evaluate the experiments that have been done to resolve the different points of view. Hudson et al. (1998), Moss and Watson (2001), and Redpath et al. (2006) discuss the differing points of view.
