Latitudinal gradient data

The data presented in the following two sheets ("Coenagrion puella" and "Pyrrhosoma nymphula") relate to individuals of Coenagrion puella and Pyrrhosoma nymphula that were collected in 2007 at a variety of sites across the UK. Details of methods, etc, can be found in the linked publication. Also, all specimens have been preserved in 95% ethanol since the project and can be accessed if somebody is interested in the population genetics of the system.
