Of course, in some cases, as in many plants and zooplankton, where movement and distribution are often a function of abiotic factors such as air and water currents, there may be little opportunity to exercise a preference, though planktonic organisms can show some habitat preference – larvae of the polychaete Spirorbis borealis, for example, vary their choice of substrate according to exposure to wave action, and become less fussy as time spent searching increases (Knight-Jones 1953; MacKaye & Doyle 1978).
