Document Summary
We can hypothesize that population size depends on environmental conditions. Nt-1= population size at some previous time step. Nt= population size at a particular time. Knowing habitat characteristics may allow predictions of abundances. They are hypothesizing/assume that abundance of ticks depends on soil moisture, wetlands, urban areas. Correlation coef cient: how much variation in you data set has been explained by the predictors in your model. Aka whether populations change over time and whether enviro changes can predict these changes. So the abundance depends on 4 enviro factors. If you put together a model with these four factors, you can predict 79% of the variation in thrip pop. If you use only 1 factor in your model, you can predict 66% of the variation in thrip pop. Hence these two are pretty similar r^2 values, so when it is something as trivial as.
