Resource Partitioning by Stream-dwelling Crayfish: The Influence of Body Size
Rabeni CF. 1985. Resource Partitioning by Stream-dwelling Crayfish: The Influence of Body Size. The American Midland Naturalist. 113(1):20-29
The crayfishes Orconectes lutues and O. punctimanus are sympatric in over 200 km of the Jacks Fork and Current Rivers in south-central Missouri. The combinations of substrate particle size, current velocity, depth and macrophyte cover used by young-of-the-year and adults of each species tend to be distinct. Other factors, most notable fish predation, probably complement physical factors and species interactions in determining the distributional patterns of these crayfishes.
