Contribution of the Order Ericales to Improving Paleoclimate Reconstructions

Paleobotanists have long built leaf climate models based on site mean of physiognomic characteristics woody dicotyledons species (WDS) for estimating past climate. To explore the potential order Ericales in paleoclimate, we developed two linear each climatic factor. One is WDS, and other both WDS characters (WDS-E). We found that, compared with models, WDS-E improved greatly annual precipitation (MAP), growing season (GSP) range temperature (MART). When minimum number three per site, r2 from 0.64 to 0.78 MART, 0.23 0.61 ln(MAP), 0.37 ln(GSP) models. For (MAT), model (r2 = 0.86) also exhibited a moderate improvement precision over 0.82). This study demonstrates that patterns, such as those Ericales, can contribute additional information towards building more precise paleoclimate
