Alternate bearing and possible long-range communication of Olea europaea

Spatio-temporal analysis typically performed in botany and in statistical physics reveals persistent correlations of olive yields which range depend on the size of the averaging region. Mapping spatially correlated regions reveals areas which mimic historical spread of Olea europaea. These yield patterns are remarkable given the intensive nature of modern agriculture, and cannot be attributed to weather due to inability of weather variables to predict yields. Long-range correlations between olive trees may indicate long-range communications.
