The European stag beetle (Lucanus cervus) monitoring network: international citizen science cooperation reveals regional differences in phenology and temperature response

Here we report on the establishment and initial findings of the European Stag Beetle Monitoring Network (ESBMN), an international network of stag beetle (Lucanus cervus) monitoring schemes using the same protocol. We found differences across European regions in the number of stag beetles recorded, related to phenology and temperature, but not for time of transect star
