Special Issue Information

Dear Colleagues,

Water saturation, soil anoxia and flooding are widely considered stressful to plants. However, numerous wetland plant species are highly productive in flood-prone areas and wetlands harbor an important compliment of regional plant diversity across the world’s biomes and climate zones. In wetlands, multiple and complex ecological gradients shape pattern at all scales of biological organization, from individuals, species, and populations, to entire communities. Temporarily or permanent anoxia, dynamic fluvial processes, specific wetland microclimates and the provision of wet dispersal corridors are only few examples of environmental factors that shape biological organization differently than those operating in strictly terrestrial habitats. Moreover, wetland plants also provide numerous ecosystem services in terms of provisioning material goods, regulating biochemical cycles, providing habitat and sustaining cultural practices. However, in the face of ongoing species loss due to climate change and human land- and water-use, a critical challenge is to understand the environmental and geographic patterns and causes of freshwater plant diversity, and how wetland plants and communities are affected through habitat loss and environmental degradation. Studies on the composition, diversity and distribution of wetland plants from local habitats to regional and even global scales in natural and man-made environments are relevant to diverse areas of scientific inquiry. This Special Issue of Plants will contribute to knowledge of wetland plants from several perspectives, such as:

  • Germination and Establishment
  • Diversity and Distribution
  • Climate Change
  • Biomass, Growth and Productivity
  • Habitat Destruction and Fragmentation
  • Population and Community ecology
  • Adaptation and Stress physiology
  • Morphology and Anatomy
  • Biogeography
  • Ecosystem Services
  • Restoration ecology

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Being adapted to saline environments, halophytes are plant species that have received considerable attention due to their ability to cope with environmental stress factors, such as high concentrations of soluble salts and heavy metals. In this work, we focused on determining if the Sarcocornia neei (S. neei) plant can be considered as an indicator of heavy metal pollution in soil. This was done by analyzing the concentration of cadmium (Cd), lead (Pb), copper (Cu), and arsenic (As) in plants and soil sampled from two wetlands in the central zone of Chile: a wetland contaminated by industrial activities and a wetland protected by the Chilean government. In addition, 14 fertility parameters (pH, electrical conductivity, organic matter, nitrogen (N), phosphorus (P), potassium (K), sodium (Na), Pb, calcium (Ca), magnesium (Mg), Manganese (Mn), zinc (Zn), iron (Fe), and boron (B)) were analyzed for soil samples in both wetlands. This was done to differentiate between available elements and contamination by heavy metals. Plant and soil samples in the contaminated wetland exhibited significantly higher heavy metal concentrations in comparison to samples analyzed from the protected wetland. This indicates that the S. neei plant can be further researched as an indicator of heavy metal pollution in saline soils and possibly for phytoremediation purposes. Full article
