There are interesting implications to be drawn from relationships such as commensalism (+, 0), in which one species benefits with no benefit or detriment to the other; amensalism (-, 0) in which the ordinary life activities of one species have an unintended negative effect on another (as when humans trample through grassland to the detriment of some plant and invertebrate animal species); and contramensalism (+, -), in which the interaction is clearly to the benefit of one species and to the detriment of the other.
