Abstract

The breeding success of female red grouse treated with an anthelmintic to reduce an infection of the nematode Trichostrongylus tenuis was compared over a period of 3 years with that of a control group. Treatment significantly increased the production of young per female in all years.
Breeding success showed a significant, negative correlation with parasite numbers in old grouse, both within and between areas (in 4 out of 5 years).
The role of parasitic nematodes in the population cycles of red grouse are discussed in relation to current models and previous studies.
