Long-term records of nitrogen in deposition and streamwater were analysed at 30 sites covering major acid sensitive regions in Europe. Large regions of Europe have received high inputs of inorganic nitrogen for the past 20 - 30 years, with an approxi

Following the decline in sulphur deposition in Europe, sulphate dynamics of catchments and the reversibility of anthropogenic acidification of soils and freshwaters became of major interest. Long-term trends in sulphate concentrations and fluxes in p

Water quality data for 56 long-term monitoring sites in eight European countries are used to assess freshwater responses to reductions in acid deposition at a large spatial scale. In a consistent analysis of trends from 1980 onwards, the majority of

The MAGIC model has been systematically calibrated to 12 sites in the UK, which form part of the UK Acid Waters Monitoring Network, using best available data. The model successfully simulates observed changes in major ions and acid neutralising capac

SUMMARY At a breeding colony on Ascension, many Black Noddies remained throughout the year. The main part of the paper describes their behaviour, with special reference to daily rhythm, sunning, absence of “panics”, nesting (with possible value o

SUMMARY The pecking of young Wideawake Terns was tested towards beak models of different colours (red, black, grey, white and silver) and towards a stuffed adult head with the normal black beak of the species. Of the colours, red and black received m

The role of vision in the prey-catching behaviour of Little Penguins Eudyptula minor was tested using four captive penguins in a swimming pool. A live fish was placed in the pool with a penguin at various light intensities before and after dawn and d

Summary. 1 The diurnal rhythm of various activities in three species of sea birds was studied in the island of Jan Mayen (lat. 71o N.) in July and August 1950. 2 The number of Fulmars flying past a certain point decreased strongly around midnight in
