Abstract Ecophysiological studies of plant species in wet saline habitats have been one-sided in the past, emphasizing sodium chloride only. More emphasis should be given to anaerobiosis, to mechanical factors, to the effects of a surplus of other nutrients in seawater and coastal ecosystems and their metabolic impact as well as to aspects of nutrient (re)allocation. Research should incorporate theoretical models on plant strategies maximizing yield, minimizing risk. At the population level, a new operational parameter for ecological optima and ecological stress is presented considering normal and skewed distributions of plant parameters in relation to growth and the concentration of mineral nutrients. Some considerations on the ecological effects of phenotypic plasticity and genetic variability are given by emphasizing the aspects of diaspores. Future investigations of coastal vegetation should consider the interaction of populations within plant communities, including the regulating effects of animals.
