Stag beetle (Lucanus cervus) monitoring data

Data from stag beetle (Lucanus cervus) transects walked at three locations: Tairnbach (8.75°E, 49.25°N, Germany, Mader 2009, 2013), Basel (7.58°E, 47.57°N, Switzerland, Sprecher-Uebersax 2001) aand Colchester (0.88°E, 51.88°N, UK, Fremlin & Fremlin 2010). Each record represents one transect walk given its date, Transect (name), Stag beetle observation (number of stag beetles observed), transect length (in hours), Moon (percentage of moon visible), temperature, rain, wind, RH (relative humidity) and Press (air pressure) at nearby weather stations during the transect walk (Arno Thomaes, Pieter Verschelde, Detlef Mader, Eva Sprecher-Uebersax, Maria Fremlin, Thierry Onkelinx & Marcos Méndez (submitted).
