Effect of diet on cast production by the megascolecid earthworm Amynthas alexandri in laboratory culture
TLDR
Feeding and casting activity of Amynthas alexandri fed on corn, wheat leaves, and mixed grasses were monitored in laboratory cultures and field samples and the C:N ratio was consistently lower than the corresponding ratio in the parent soil.
Population dynamics of the earthworm Amynthas alexandri (Megascolecidae: Annelida) in cultivated soils of the Kumaun Himalayas
TLDR
The population dynamics of the earthworm Amynthas alexandri was observed over 2 years in cultivated soils at Chanfi and Khurpatal near Nainital and the C: N ratio of the soil decreased with increasing depth in both localities.

TLDR
Good synchronization was observed in the life cycle of acorn weevils and phenology of Q. leucotrichophora, and injury to live acorns by weevil larvae reduced germination and seedling growth.
