Predicting the Potential Distribution of Rare and Endangered Emmenopterys henryi in China Under Climate Change

Ecology and Evolution, Volume 14, Issue 10, October 2024.
We applied Biomod2 and MaxEnt to predict the current and future potential distribution of endangered Emmenopterys henryi in China. The current potential distribution area from Biomod2 is 176.53 × 104 km2, which is larger than from MaxEnt. Moreover, climate change is expected to have an adverse effect on its potential distribution.

Subduction polarity of the Ailaoshan Ocean (eastern Paleotethys): Constraints from detrital zircon U-Pb and Hf-O isotopes for the Longtan Formation

, 2020
The Paleotethys Ailaoshan Ocean separated the South China and Indochina blocks during the late Paleozoic. Uncertainty remains regarding subduction of this ocean- whether it was subducted eastward beneath the South China block or westward beneath the ...
