Abstract:
To investigate the availability of peptides in the soils on Signy Island, soil solutions were sampled throughout the summer season, from mid November 2008 until early March 2009. Soil solution samples were extracted under vacuum, with minimal disturbance to the soil, through small porous tubes. A total of 19 sites across the island were sampled in areas dominated by all the major primary producers, vascular plants, mosses, algae and lichens. The collected soil solution samples were analysed for different forms of nitrogen, including peptides.
