Data on bee colony dynamics and health used in this study "Requier et al. (2016) Pollen shortage negatively impacts bee colony survival. Journal of Applied Ecology"

The data available came from part of ECOBEE, a long term ecological research program set up to monitor honeybee colonies in a context of real professional beekeeping practices in the Poitou-Charentes region in central western France (46°23’N, 0°41’W). Over five consecutive years, from 2008 to 2012, the colony dynamics were monitored by measuring three core colony traits: the amount of brood in the colony (termed brood size), adult population and honey reserves, bimonthly throughout the monitoring period. This dataset also include the Varroa mite load (assessing using a sticky board placed at the bottom of the hive brood chamber, and the seasonal and witner colony survival (the criteria for the seasonal survival and the overwintering survival of the colony were whether the colony remained operational for beekeeping activity during the season or after winter arousal, respectively). All the colonies came from an A. mellifera mellifera × caucasica strain and were managed in accordance with local professional beekeeping practices, without migration, with honey collections, systematic supplemental feeding with syrup when necessary, and systematic treatment against Varroa mites. (see Odoux et al. 2014 for more details). Complete details may be found in "Requier et al. (2016) The carry-over effects of pollen shortage decrease the survival of honeybee colonies in farmlands.
