Long-term monitoring of roller dung beetles (Scarabaeinae) (abundance and distribution) in Do?ana 2004-2012

The monitoring of the roller dung-beetles (Scarabaeinidae) in Do?ana, southwestern Spain, was initiated in 2004 as part of the Monitoring Program of Natural Resources and Processes. The aim was to obtain a temporal and continuous series of data in the abundance and distribution of two species (Scarabeus sacer and S. cicatricosus) present in the area. Data were recorded annually from 2004 to 2012 by members of the monitoring team which performed one sampling (between May and August) in different habitats (sand dunes, mediterranean schrublands, flooplain meadows, and marshlands).
