    Int J Parasitol 32:991-6. 2002
    ..It is concluded that due to the intensity dependence in nematode fecundity, variation in reindeer population densities is likely to be the most important of these factors for pasture contamination...

    R J Irvine
    Institute of Terrestrial Ecology, Hill of Brathens, Banchory, UK
    Parasitology 120:297-311. 2000
    ..O. gruehneri may therefore play a role in the fluctuating population dynamics of the host. Since there was no apparent decline in abundance with host age in any of the 3 taxa there was no evidence of reindeer mounting an immune response...

    R J Irvine
    Centre for Ecology and Hydrology, Banchory, UK
    Parasitology 122:673-81. 2001
    ..The contrasting patterns of density-dependent regulation of fecundity provides further evidence for divergent life-histories in this nematode community...
  4. pmc The role of parasites in the dynamics of a reindeer population
    S D Albon
    Centre for Ecology and Hydrology, Hill of Brathens, Banchory AB31 4BW, UK
    Proc Biol Sci 269:1625-32. 2002
    ..This model shows that the parasite-mediated effect on fecundity was sufficient to regulate reindeer densities around observed host densities...
  5. ncbi Sex ratio variation in gastrointestinal nematodes of Svalbard reindeer; density dependence and implications for estimates of species composition
    A Stien
    Department of Biology, University of Tromsø, N 9037 Tromsø, Norway
    Parasitology 130:99-107. 2005
    ..Our results suggest that estimating sex ratios can be particularly important in individual host level studies of nematode species of low abundance...
