A new study published in the journal Environmental Entomology shows that invasive Japanese barberry reduces numbers and diversity of arthropod communities in forests where it has spread. In this schematic diagram, solid boxes indicate trophic relationships (herbivory, detritivory, predation), while dotted boxes indicate mechanisms by which Japanese barberry might alter arthropod food webs.
