The potential importance of Juncus acutus for remediation of Zn-contaminated lands has been recognized, because of its Zn tolerance and capacity to accumulate Zn. Since it is also a halophyte, the extent to which salinity influences its Zn tolerance requires investigation. A factorial greenhouse experiment was designed to assess the effect of...

Background and Aims: Halophytic species often show seed dimorphism, where seed morphs produced by a single individual may differ in germination characteristics. Particular morphs are adapted to different windows of opportunity for germination in the seasonally fluctuating and heterogeneous salt-marsh environment. The possibility that plants...

Selection pressures associated with strong environmental gradients on salt marshes provide a mechanism for the genetic subdivision of species. We investigated the importance of differentiated habitat niches in explaining the distributions of 2 forms of the halophyte Sarcocornia perennis: ssp. perennis in lower/middle marshes and the Iberian...

Background and Aims: Atriplex(Halimione) portulacoides is a halophytic, C3 shrub. It is virtually confined to coastal salt marshes, where it often dominates the vegetation. The aim of this study was to investigate its growth responses to salinity and the extent to which these could be explained by photosynthetic physiology. • Methods: The...
