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.

“…For instance, in some cyanobacteria there is no PMEase activity under phosphate-rich conditions and PDEase activity is induced at the same time as PMEase activity (Whitton et al, 2005). The concentrations of nutrient elements and phosphatase activities of mosses can provide a record of the nutritional status of the environment (Steinman & Boston, 1993;Steinman, 1994;Garcia-Alvaro et al, 2000;Whitton et al, 2002). As the aquatic mosses whose phosphatase activities have been reported in detail mostly come from streams and small rivers where peat is important in the catchment, but with the pH of the water typically near neutral, it was decided to investigate the surface phosphatase activities of a moss from a quite different environment, an acidic stream.…”

Phosphatase activities of the aquatic moss Warnstorfia fluitans (Hedw.) Loeske from an acidic stream in North-East England

A study was made of the aquatic environment, tissue nutrient composition and surface phosphatase activities of the aquatic moss Warnstorfia fluitans in Brandon Pithouse Stream, a small acidic stream in N-E England. The water, which originates from an underground spring, had been pH 2.6 for at least 30 years, but about 3.9 during the present study. The moss was by far the most abundant phototroph during all this period. Seasonal changes in aqueous nitrogen and phosphorus fractions were measured over a 2-year period near the source. Most of the filtrable N and P were at times organic, but the very high N:P ratio (even if organic N is excluded) suggests that only organic phosphate is likely to be important Handling editor: S. M.

“…Samecka et al [26], Cesa et al [27], and Herrera-Núñez et al [29] showed that the concentration of these metals in urban rivers is mainly due to the activities of textile and manufacturing industries, which are not present along the Zamora urban river. In addition, concentrations of these metals in natural waters are highly influenced by the presence of acid rain and atmospheric deposits [30], and stone extraction activities that affect deep beds [17].…”

“…They show key characteristics that set them apart from other bioindicators: (A) many species are widely distributed, (B) contaminant absorption of chemicals is passive, and not significantly affected by biotic factors, (C) they are resistant to high levels of water contamination, (D) they are rarely invasive, and (E) they can bioaccumulate metals above their physiological needs due to the absence of a cuticle in their tissues [10]. Certain aquatic bryophyte species have been widely used in recent years as bioindicators [5,[15][16][17][18][19]. For instance, Fontinalis and Platyhypnidium bryophytes are the best-studied genera in terms of passive biomonitoring of metals in water, with observations from several regions in the world with chronic exposures or long-term effects of contaminants [10,[20][21][22][23].…”

Platyhypnidium aquaticum as Bioindicator of Metal and Metalloid Contamination of River Water in a Neotropical Mountain City

Water contamination is a major environmental problem in many cities of the world. Most water contamination results from industry and human activities that generate toxic substances (e.g., metals). Rheophilic and aquatic mosses are found in lotic ecosystems, and their morphological and physiological traits are responsive to ecological and pollution gradients. Here we hypothesized that the native rheophilic moss Platyhypnidium aquaticum (A. Jaeger) M. Fleisch exposed to polluted waters can bioaccumulate greater amounts of metals, and a metalloid, than P. aquaticum exposed to pollution-free water. To this aim, we tested the bioindicator capacity of the aquatic P. aquaticum for 15 metals (Cd, Pb, Zn, Fe, K, Ca, Na, Mn, V, Co, Ba, Cr, Al, Sr, and Mg) and one metalloid (As), in twelve river samples coming from three urban and one control zone along the Zamora river in the city of Loja. When compared to the control, our results showed that P. aquaticum in the Southern, Central, and Northern zones of the city bioaccumulated higher concentrations of Ba, Cd, Co, Fe, Mg, Mn, Na, Sr, Zn, and the metalloid As. On the other hand, concentrations of Al, Ca, Cr, Pb, and V in P. aquaticum tended to be lower in the control zone, but these differences were not significant. We suggest that the presence of these contaminants may be related to water pollution (e.g., residual discharges and a lack of treatment systems) along urban zones of the river. We report for the first time the utility of P. aquaticum as a model species for development of long-term biomonitoring programs of water contamination in South America. Passive biomonitoring with P. aquaticum can be a simple and low-cost method to obtain reliable data of the current state of water contamination with metals and metalloids in tropical regions.
