The Effect of Coprophagous Beetles (Coleoptera: Scarabaeidae, Geotrupidae, and Hydrophilidae) on Methane Emission Rates and a Six-Month Species Comp...
Cattle and farming practices are a growing source of methane emissions. This young naturalist hit the pasture to see firsthand if dung-eating beetles could help reduce greenhouse gas emissions.
Pumpkin Purifier: Removal of Toxic Metals from Water Using Curcurbita Agricultural Waste
Because heavy metals enter water through many sources, scientists are motivated to develop purification and extraction methods. Some of these techniques have been successful, but at great cost or with detrimental effects to the environment. The purpose of this experiment was to determine if the agricultural by-product Curcurbita (pumpkin) could be used to remove metal ions from an aqueous solution.
