How do we know our research results are REAL? We replicate them! Most folks agree but lament on how hard it is to publish these replications.

Treehoppers: Membracidae & Aetalionidae - Alex Wild A gallery of treehoppers, a specialized lineage of leafhoppers with highly modified pronota.

A gallery of treehoppers, a delightful lineage of sap-feeding, singing insects with a bizarre assortment of body ornaments.

First, the frogs died. Then people got sick. An emerging area of research is uncovering hidden links between nature and human health.
