“…Negoro (1985) found this species well distributed in acidic habitats in Japan, with pH variation between 2 and 4 and temperatures of 20.5°C to 46.8°C; Watanabe and Asai (1995) quoted this taxon also in Japan, in sites of pH below 1.1; and Sabater et al (2003) found this taxon in an acid stream of southwestern Spain, the Rio Tinto (same geological unit: IPB, as Aljustrel). This taxon has a variable morphology and resembles Pinnularia obscura Krasske (Carter 1972), both recorded in other sites: England (Hargreaves et al 1975), North America (Whitton and Diaz 1981) and South Africa (DeNicola 2000).…”

Aljustrel mining area is located in the Iberian Pyrite Belt, one of the greatest concentrations of massive sulphide deposits that extends from Lousal (Portugal) to Aznalcóllar (Spain). The surrounding streams, Roxo, Água Azeda and Água Forte, are influenced by the erosion of the tailing deposits and the input of acid mine drainage (AMD) from the abandoned Aljustrel pyrite mines, recently reopened in 2007. The purpose of this study was to understand how these adverse conditions influenced the stream sediments, water quality and periphytic diatom communities and establish the pre-restoration local conditions to judge the success of rehabilitation program now under way. For stream sediments, the highest metal concentration samples were found at sites F, G and H. Arsenic, Cu, Fe, Pb and Sb detected concentrations, generally exceeded the probable effect concentration values reaching level 4: the highest toxicity level. In surficial water samples of AMD affected sites (F, G and H), low pH values (1.5 to 3.5) and high metal concentrations of As (6,837 μg L

“…Studies carried out at seven sites over one year (Wehr & Whitton 1983) led to only a very slight reduction in pH limits (pH 6.4). Rhynchostegium is absent from highly acidic streams even if they are calcareous or rich in nutrients (Hargreaves et al 1975;Whitton & Diaz 1981).…”

A study was made of general ecology and metal accumulation in the widespread aquatic moss Rhynchostegium riparioides, (Hedw.) C. Jens. with a view to developing the use of this species as a monitor of heavy metal pollution. In order to establish a data bank for statistical analysis, samples of water and moss were taken within a 6-week period from 105 sites (10-m reaches) in Northern England from streams and rivers of diverse physical and chemical types. Analyses were made of 14 metals (Na, Mg, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Ba, Pb) in both 2-cm tips and whole plants. The same 14 metals were also measured in both total and filtrable water, together with 12 other variables. Samples of tips were easier to prepare for analysis, but had significantly (p < 0.001) lower concentrations of all metals except Na and K. Significant correlations (p < 0.001) between metal in moss and aqueous metal were found forten metals(Na, K, Mg, Ca, Mn, Cu, Zn, Cd, Ba, Pb). Correlations between metals in moss and in water were in general similar for tips and whole plants, but much higher for tips with Na, Zn and Cd; the relationship was quite similar whether total or filtrable water was considered, with the exception of Ba where the correlation was much higher with the latter. A multiple regression was used to suggest which variables in water and/ or moss may influence accumulation of Co, Ni, Cu, Zn, Cd, Ba and Pb in the moss. For instance, the variables which had a very highly significant effect on Pb in tips were Pb, filtrable reactive phosphate and Zn in the water. A discussion is included of how the data may be used for monitoring purposes.

“…This taxon has a variable morphology resembling P. obscura KrassKe (carTer 1972). Both species, P. acoricola and P. obscura, were observed in waters with low pH in England (Hargreaves et al 1975), North America (WHiTToN & diaz 1981) and South Africa (deNicoLa 2000). Apparently, these diatoms seem to be well adapted to low pH conditions allowing them to develop large communities in otherwise inhospitable environmental conditions.…”

A new benthic freshwater diatom species belonging to the genus Pinnularia eHreNb. has been recorded in the Água Forte stream surrounding the Aljustrel mining area in southern Portugal. Pinnularia aljustrelica Luís, aLmeida et ecTor sp. nov. is described as a new species based on light and scanning electron microscopy observations and on its particular habitat in an acidic environment due to acid mine drainage, high metal concentrations (As, Cd, Cu, Fe, Mn, Pb and Zn) and high sulphate and conductivity. The taxa most similar to P. aljustrelica are P. acidophila HoFmaNN et Krammer, P. acoricola HusTedT and P. acoricola var. lanceolata HusTedT, so type materials of these taxa were studied for comparative purposes. Although, the ecology of the three similar taxa is also quite similar, the new species has a combination of particular morphological characteristics studied under LM and SEM that separates it from the rest. Pinnularia aljustrelica has a general shape relatively similar to P. acidophila and P. acoricola, but the valve outline is not as linear as in P. acidophila and not as oval as in P. acoricola.
