limes convergens The Latin name (limen means ‘threshold’) given to a well-defined boundary zone between two fairly uniform major habitat types. An example is a flood meadow zone, which is subject to periodic catastrophic flooding: this includes species characteristic of wet conditions, as well as those typical of trampled and grazed areas (which reflect the normal use when the area is not flooded).
