N2 - On the island of Rhum (Inner Hebrides: Western Scotland) several taxonomically diverse species of small crustaceans live in water that is more acidic and of lower ionic content than that in which they have ever been found in Yorkshire (England). Physiological difficulties appear to be experienced by these species in Yorkshire in waters that would evidently be suitable in Rhum. This may be due to the presence of heavy metals and other substances derived from atmospheric pollution, of which Rhum is largely free, that act synergistically with other stressful factors. Evidence from other areas is in agreement with this suggestion. The few species that are specialised for life in highly acidic water can frequent more acidic conditions in Yorkshire than any encountered on Rhum. Nevertheless certain species that are common in the Northern Pennines have not been found in the Southern Pennines where pollution has been most intense. One species that is common in the Northern, but has not been found in the Southern Pennines, formerly occurred there as shown by abundant remains in the peat.
