Transitional Waters

Ecological status groups and traits for transitional water marine benthic vegetation

Ecological Status Groups Coastal Waters

By studding morphological (external morphology, internal anatomy, texture), physiological (surface area/volume ratio, photosynthetic/non-photosynthetic ratio, photosynthetic performance, growth, light adaptation) and life history (longevity, succession) traits along with distributional data across eutrophication gradients two main groups of transitional water benthic macrophytes were identified: the slow-growing, late-successional species (ESG I) and the fast-growing, opportunistic species (ESG II). Both groups were hierarchically divided into three sub-clusters:

  • ESG I comprises thick perennial (IA), thick plastic (IB) and shade-adapted plastic species (IC), and
  • ESG II comprises fleshy opportunistic (IIA) and filamentous sheet-like opportunistic (IIB) species and species of fresh water affinity (IIC, e.g. Potamogeton sp.).
