Nevertheless, it may be difficult to extrapolate our results to natural conditions as we (1) have not considered
potential changes in biotic interactions (Sentis et al., 2013), (2) did not quantitatively assess changes in host plant quality due to heat stress and only included low
relative humidity as an additional factor (Bauerfeind and Fischer, 2013a), (3) did not consider effects of different host plants (Bauerfeind and Fischer, 2013b), and (4) did not apply temperature variation in the adult stage.
The lower
relative humidity and increased temperatures that would result from
potential reductions in fog and low cloud cover could increase plant evapotranspiration rates, raise soil water deficits, and accelerate risks of forest fire.
