Hydrogeochemical processes of groundwater system and its mining-motivated effect in mining areas of Western China

Meitan xuebao
The exploitation of coal resources will destroy the aquifer structure, disturb the groundwater system and produce a new water cycle model. As the focus of coal supply and production, the western mining area is short of water resources and fragile in ...

Fossil evidence for key innovations in the evolution of insect diversity [PDF]

, 2014
Explaining the taxonomic richness of the insects, comprising over half of all described species, is a major challenge in evolutionary biology. Previously, several evolutionary novelties (key innovations) have been posited to contribute to that richness ...
