The physical variables influencing the distribution and abundance of Tubifex tubifex in stream habitats are not well understood and could have implications for the success of using resistant T. tubifex lineages to manage whirling disease. Our primary objective was to evaluate if sediment size distribution and other physical microhabitat factors were associated with lineage composition of T. tubifex. Our second objective was to randomly sample stream habitats to gain a more complete understanding of T. tubifex distribution across a wide variety of stream habitat types.
