The relationship between increasing average annual surface air temperature and establishment rate of IAIs remained significant after inclusion of the annual value of imported merchandise in the regression models during 1951–2005, using either the 11-year moving average time series or simply the annual values (Table 2

This analysis is clearly invalid because he authors failed to detrend their series prior to analysis. Any relationship here is quite likely to be spurious. In the field of time series analysis it is well known that regressing one nonstationary series on another will yield a spurious association.
