This analysis showed that although these STs were
closely related on a whole - genome level, they demonstrated evidence of multiple recombination events that were unlikely to have occurred
over the
timeframe of the outbreak.
Winter precipitation (mean and extreme) variability and trends along the south coast and interior of Alaska appear to be
closely related to variations in the PNA pattern
over this
timeframe, while El Nino / Southern Oscillation (ENSO) influences, through the Nino3 index, appear to be significant along the south coast alone.
