“…For example, in the streams of the Vosges Mountains (France), studied by Claveri et al (1995), draining the granitic Rouge-Rupt river basin, Hygrohypnum ochraceum was widespread and tended to occur with Pellia epiphylla in particularly acid conditions corresponding with the Group II species assemblage of our study. Also recorded as frequently occurring together in other central European streams, Scapania undulata, Platyhypnidium riparioides and Fontinalis antipyretica, constituent species of the Group II community in our study, characterized the bryophyte assemblages of streams draining similarly base-poor geologies including the Ore Mountains in Germany (Samecka-Cymerman et al, 2002), and Tatra Mountains in Poland (Samecka-Cymerman et al, 2007). Group II appears to represent an extensively occurring stream bryophyte community typical of little-impacted upland ecosystems, in moderate to high latitudes in Europe, supporting an assemblage present on resistant basepoor geologies, with inherently oligotrophic, weakly buffered and acid-sensitive streamwater chemistry, experiencing elevated levels of sulphate and metals.…”

“…In order to include upland headwater ecosystems in macrophyte-based river bioassessment schemes it is necessary to amass data on the flora and environmental physico-chemistry of ''reference'' quality (minimally impacted by anthropogenic activity) streams, supporting ecological benchmark communities, against which impacted ecosystems can be compared. Examples of studies on impacted stream bryophyte communities include those exposed to anthropogenic perturbations caused by metal pollution (Satake et al, 1989b;Claveri et al, 1995;Siebert et al, 1996;Yoshimura et al, 1998;Vincent et al, 2001;Samecka-Cymerman et al, 2002), acidification (Ormerod et al, 1987;Stephenson et al, 1995;Thiebaut et al, 1998;Stetzka & Baumann, 2002), nutrient enrichment (Stetzka & Baumann, 2002), other pollution (Empain, 1978;Kosiba & Sarosiek, 1995) and flow regulation (Englund et al, 1997;Vanderpoorten & Klein, 2000).…”

Environmental drivers, life strategies and bioindicator capacity of bryophyte communities in high-latitude headwater streams

This study reports an investigation of the bryophyte ecology of minimally impacted high-latitude headwater streams, to assess the hypothesis that underlying geology, water physico-chemistry, current velocity and substrate morphology are significant environmental drivers of the species distribution, community composition and abundance of bryophyte vegetation in these naturally highly stressed and disturbed upland ecosystems. Our secondary aim was to determine whether there is evidence that the assemblage and functional attributes of the species present have potential as indicators of water quality and habitat biointegrity in high-latitude headwater streams. The methodology involved repeated intensive surveys, during 2005-2006, at nine sites located on three streams of contrasting underlying geology, within latitudes 56°-58°N, in upland Scotland. Using a stratified random sampling design, quantitative assessments were made of 5 stream vegetation parameters and 52 environmental variables potentially influencing the target sites. TWINSPAN classification, supported by CCA ordination, of the dataset identified four stream bryophyte community types, plus a fifth sample group (characterized by unstable habitat conditions) devoid of bryophytes. The environmental drivers of the vegetation community were primarily associated with streambed stability (flow, substrate composition) and water chemistry (e.g. pH, conductivity, Ca 2? ), which were products of the prevailing underlying geology. The abundance of stream bryophytes was generally a function of predominant growth morphology and life strategy of the species present. Two bryophyte assemblages were identified as characterizing either upland oligotrophic stream habitats of acid-sensitive and base-poor waters (indicators: Scapania undulata, Hygrohypnum ochraceum), or calcareous and mineral-rich streamwaters (indicators: Chiloscyphus polyanthus, Hygrohypnum luridum). The results support the incorporation of bryophytes into river biomonitoring schemes, for use in high-latitude upland streams.

“…Consequently, they were widely used as biosensors of environmental pollution (Samecka-Cymerman et al 2002;Zechmeister et al 2003) and as models for morphological and genomic alteration caused by heavy metals (Bassi et al 1995). However, effects of pollutants on plants could be determined at several levels, from changes in biological and physiological processes (Darrall 1989) through organs and whole-plant level responses, e.g., growth inhibition, reduction of yield, and/or foliar injury (Taylor 1984), to changes in plant communities (Folkeson and Andersson-Bringmark 1988).…”

The short-term responses and mechanisms of antioxidants in moss Hypnum plumaeforme subjected to single or combined Pb and/or Ni stress has been revealed in this study, in order to clarify (1) the relationship between the stress intensity and antioxidant fluctuation, (2) the difference between single and combined stress, and (3) the possibility of biomonitoring by the application of antioxidant fluctuation under stress. The results showed that the stress induced dose dependent formation of reactive oxygen species (ROS) and subsequent lipid peroxidation. Total chlorophyll (Chl) content and superoxide dismutase (SOD) activity were initiated under lower stress but were inhibited under higher stress. Both single and combined stress decreased catalase (CAT) activity but increased peroxidase (POD) activity, indicating POD in the moss played an important role in resisting the oxidative stress induced by Pb and Ni. The accumulation of (.)O2(-) and H2O2 in H. plumaeforme was respectively related to the low activity of SOD and the decreased activity of CAT. The study indicated that Pb and Ni had synergistic effect in inducing the oxidative stress in moss H. plumaeforme, especially under the combination of high concentration of Ni (0.1, 1.0 mM) and Pb. POD and CAT activity, as well as H2O2 and MDA content, which increased or decreased regularly with a dose dependent under Pb and Ni stress, could be used as an effective indicator in moss biomonitoring, especially in the case of light pollution caused by heavy metals without the changes in the appearance of mosses.

“…53 While it has been hypothesized that the measured levels of U in terrestrial mosses may underestimate contamination concentrations due to adaptations that allow them to exist in highly contaminated areas, this relationship has not been observed in aquatic mosses. 54 If a CR value were calculated for mosses associated with the outfall and stream outfall areas, the average speculated value would be ~6.…”

Bio-monitoring for uranium using stream-side terrestrial plants and macrophytes

et al. 2012

This study evaluated the abilities of various plant species to act as bio-monitors for environmental uranium (U) contamination. Vegetation and soil samples were collected from a U processing facility*.The water-way fed from facility storm and processing effluents was the focal sample site as it represented a primary U transport mechanism. Soils and sediments from areas exposed to contamination possessed U concentrations that averaged 630 mg U kg Strontium is chemically and physically similar to calcium (Ca) and magnesium (Mg), which were also positively-correlated with U. The correlation with U and these plant nutrient minerals, including iron (Fe), suggests that active uptake mechanisms may influence plant U accumulation.
