Freshwater aquatic invertebrates on the Isle of May, Scotland

Abstract

The invertebrate fauna of freshwater habitats on the Isle of May, Scotland was investigated and compared with the results from surveys undertaken in 1958. Overall, the freshwater invertebrate fauna appears to be diminished. However, several species were recorded as new to the Isle of May. Although the reasons for the apparent decline in freshwater invertebrates on the island are unclear, an increase in the temporary nature of the habitats due to climate warming may be a contributing factor.
