It could be argued that in warmer, wetter climes, an increase in resource availability enabled both taxa to co-exist.
In detail, this trend appears to have been highly irregular, with alternating stratigraphical intervals containing indicators of drier and wetter conditions.
In conclusion, the species strongly favours wetter forests.
Higher values of this ratio are associated with drier times, and lower values with wetter times.
It helps to explain why adoption of new varieties is often faster in the wetter areas.
A baseflow regression model predicts that drought mitigation attributed to increased forestation is typically concentrated in the wetter southern watersheds.
Only a wetter-thanaverage period could enable the system to recover.
Patterns of litterfall suggest that the driest site may be slightly more productive than wetter forests.
