Stocks of the freshwater crayfish in Ireland are thought to be some of the largest in Europe. To better protect this species, it is necessary to update data on the geographical distribution of Austropotamobius pallipes on the island. Records from surveys carried out by the Environmental...
Trichomanes speciosum , which was collected extensively during the Victorian fern craze, is one of the rarest pteridophyte species in Ireland and is protected by both the Wildlife Act, 1976, and the European Union Habitats Directive, 1992 92/43/EEC. Since the discovery in the wild of the...
Seasonal stratification in Lower Lough Erne, north-west Ireland was studied between 1991 and 2000. Oxygen depletion rates from the profundal water (below 40m depth) are reported for each year. The mean depletion rate for all years was 0.459g O 2 m -2 d -1 . Values varied approximately two-fold...
Substrates from four-and-a-half year old constructed wetlands built to treat wastewater from an active metal mine were analysed for elevated metal and sulphur concentrations by chemical sequential extractions and X-ray diffraction analyses. Amounts of Fe, Pb, Zn and S were quantified in...
The Avoca–Avonmore catchment contains some of the most polluted stretches of river in Ireland, with acid mine drainage having a profound impact on the lower 15km of river. An inventory of selected heavy metal concentrations in riverine sediments was used to assess the health of the river as well...
Temporal variability in neuston diversity and community structure in Lough Hyne Marine Nature Reserve, Co. Cork, was studied over a two-year period. Neuston sampling was carried out at different time scales in order to make between-year, seasonal and monthly comparisons and, in May 2003, at...
