“…Although bryophytes are generally considered to be non-halophytes, some species can tolerate high salt content in the substrate (Sabovljević & Sabovljević 2007;Ćosić et al 2019). Bryophytes can be divided into three groups based on their ability to grow on saline substrates: obligatory halophytes, which grow exclusively on saline substrates; facultative halophytes, which can survive on saline substrates, but grow and develop better on substrates without salt or with low salt concentration; and indifferent species, which can grow on saline substrates as successfully as on substrates without salt (Sabovljević & Sabovljević 2007).…”

Effects of salt on selected bryophyte species tested under controlled conditions

Bryophytes inhabit all ecosystems on the Earth except seas. Thus, it is commonly accepted to ask are there real halophytes among bryophytes? However, some species do inhabit salty grassland or even brackish waters. Not much research has been done on the physiological reaction of moss species to salt stress. In order to study these responses, we selected three moss species, two of which are considered to be halophytes−Entosthodon hungaricus (Funariaceae), Hennediella heimii (Pottiaceae) and the non-halophytic model moss Physcomitrella patens (Funariaceae) and tested salt effects on them in controlled conditions. The idea was to show if there is tolerance to salt in the selected moss species and to document it if there is a difference in salt tolerance among them. Established in vitro moss cultures of gametophores were used to test various developmental parameters for the selected moss species. Morpho-developmental parameters (secondary protonema diameter and the index of multiplication) and biochemical parameters (pigment content and antioxidative capacity) were analysed in relation to salt concentration and time of exposure. All of the tested moss species tolerated salt stress to some extent and during some time of exposure to it. Recovery after salt stress depended both on the concentration of salt and duration of the stress. The three tested moss species did not show similar patterns of response to salt stress.

“…Figures of physicochemical changes for the remaining trace elements are presented in the Supplementary Materials (Figures S1–S4) . The increase in the solution’s conductivity after the insertion of mosses into the solution was caused, among other things, by the dissolution of salts naturally accumulated on the surface of the mosses and progressive, irreversible changes in the structure of cell membranes over time, which cause the leakage of ionic substances from moss cells to the solution [ 39 , 40 , 41 ]. This process can be observed using conductivity measurements to track the kinetics of metal sorption on mosses that have been stored for 6 months ( Figure 2 ).…”

The interrelationship between metal concentrations in mosses and their surroundings prompts research toward examining their accumulation properties, as it is particularly important for their usage in biomonitoring studies that use mosses. In this study, the kinetics of elemental sorption in three moss species (Pleurozium schreberi, Dicranum polysetum, and Sphagnum fallax) were investigated under laboratory conditions. Sorption from metal salt solutions was carried out under static conditions with decreasing elemental concentration. Functional groups responsible for binding metal cations to the internal structures of the mosses were also identified. It was shown that the equilibrium state was reached after about 60 min. Under the conditions of the experiment, in the first 10 min of the process, about 70.4–95.3% of metal ions were sorbed from the solution into the moss gametophytes by P. schreberi (57.1–89.0% by D. polysetum and 54.1–84.5% by S. fallax) with respect to the concentration of this analyte accumulated in the mosses at equilibrium. It can be assumed that the exposure of mosses with little contamination by heavy metals in an urbanized area under active biomonitoring will cause an increase in the concentration of these analytes in proportion to their concentration in atmospheric aerosols. In the case of P. schreberi and D. polysetum, the O-H/N-H band was enormously affected by the adsorption process. On the other hand, FTIR (Fourier transform infrared spectroscopy) analysis of S. fallax after adsorption showed slight changes for most of the bands analyzed. Based on this study, it can be concluded that mosses can be used as, for example, a biomonitor in monitoring of urban ecosystems, but also in the phytoremediation of surface waters.

“…R. H. Zander, can be seen in salt-stress survival [ 35 , 36 , 37 , 38 ], differing between species in chemical content quantity and quality when growing in the same controlled conditions, and applying them in salt-stress tolerance and resistance. The state of knowledge on salt stress in bryophytes can be found in more detail in Ćosić et al [ 39 ], and bryophytes have already been reported to have different responses to salt stress to those present in poikilohydric ferns, for example [ 40 ]. The addition of nitrogen and phosphorus to wet paper was enough to get well-developed rare and endangered Tayloria splachnoides (Schwägr.)…”

An introduction to the conservation physiology of bryophytes is given. The insights into the problems, solutions and examples of the physiological approach to conservation within bryophyte representatives are discussed. The significance of experimental treatments of bryophytes is highlighted. The documentation of bryophyte functional traits and eco-physiological mechanisms in the conservation background for protection purposes is highlighted by the selected examples. The introduction of bryophytes into a new scientific field is resumed and some insights from specific case studies are presented.
