Macroinvertebrate biomass was highest at an intermediate riparian ecotone complexity with an adequate supply of organic matter and incident light. Fish biomass followed the same trend, being lowest in heavily shaded areas and in open channels without riparian vegetation (range: 1-4.5 g m-2), but highest in ecotones of intermediate complexity (range: 1.6-92.8 g m-2). The cascading effect of invertebrate density depletion, which was inversely related to fish biomass, was observed seasonally. Wiley InterScience
The complexity and biological importance of riparian ecotones depend on the extent to which the system is self-regulating, which depends in turn on geology, physiography, climate, vegetation, human activity and the age of the system. Fish and riparian ecotones – a hypothesis
A common example of ecotones is estuaries—the transitional area between rivers and the oceans. The variety of species found in an estuary is much higher than in the river or in the shallow sea-water. BASICS OF ECOLOGY & LIFE SUPPORT SYSTEMS
Ecotone is a general term and should not be transl

Ecotone: a general term coined in 1903 meaning environmental stress zone, later mainly used for a sharp transition zone between two types of environment/community. I have commented on the term earlier, but the discussion goes on. Here a second attempt. See further van der Maarel, Journal of Vegetation Science 1: 135-138, 1990. Electronic reprint available via email@example.com
General: who knows how to reach the manager of this discussion forum; I have failed so far. I wish to get rid of some constraints, e.g. unrealistic limits in size (see above) and the requirement to give 3 example sentences. I tried to introduce a term and had only 2 sentences available and was simply denied access. I stopped participating, until "ecotone" turned up, a term I have published on!
