Palmer amaranth's molecular secrets reveal troubling potential

Corn, soybean, and cotton farmers shudder at the thought of Palmer amaranth invading their fields. The aggressive cousin of waterhemp—itself a formidable adversary—grows extremely rapidly, produces hundreds of thousands ...

A modeling tool to rapidly predict weed spread risk

In the study, published in the journal Methods in Ecology and Evolution, the researchers developed the tool that uses information about the features of a weed species and the geography of the area in which it has been reported ...

Why is Earth so biologically diverse? Mountains hold the answer

What determines global patterns of biodiversity has been a puzzle for scientists since the days of von Humboldt, Darwin, and Wallace. Yet, despite two centuries of research, this question remains unanswered. The global pattern ...
