The effect of reduced density is augmented by the lag that develops between the evolving focal plant and pollinator phenologies, which further reduces the per capita interaction rate between the focal populations.
The final model included age-specific seasonal effects and linear time trends; cross-sectional and longitudinal components of BAC laws, unemployment rates, and per-capita personal income; and interactions between each age group and longitudinal and cross-sectional components of gasoline prices, maximum Interstate highway speed limits, and all licensing policy variables.
A Poisson GLM with plot nested within treatment and controlling for the estimated per capita rate of female-male interactions (i.e. including the cohabitation rate as a covariate), showed that the interaction rate per se did not significantly affect the rate of sexual cannibalism (F1,52 = 0.3, P = 0. 615).
We investigated the potential for cross-habitat interactions to modulate per capita ungulate browse effects on forest herbaceous layers.
Interestingly, the coefficient of this interaction is very similar with the opposite sign to the one for interaction of GDP per capita of the destination country and distance (indeed, we cannot reject statistically that their magnitudes are the same p-value isame p-valuen the table notes).
This would tend to produce a larger linear effect of destination country GDP per capita, but it would not affect the interaction term.
Interaction between HDI and per capita family income was also assessed.
An interaction between HDI and per capita family income was statistically significant with dental pain prevalence in unadjusted analysis (p < 0.01) but this association disappeared when adjusted for the variables in the multivariable model (p = 0.900).
Interaction terms were also tested, such as the interaction between capacity utilization and GDP per capita.
Furthermore, our interest is estimating the joint effect of the interaction between region-level GDP per capita and worker age.
