Arthropods are among the most diverse groups in eukaria. However, due to a rise in land-usage globally, arthropod biomass in these ecosystems is currently on the decline. Seibold et al. used anually sampled grasslands to measure biomass, abundance, and number of species of arthropods, discovering that these numbers have declined by 67%, 78%, and 34% respectively1. These losses are not isolated to grasslands, however, as declines in forests were also observed. According to the study, policy reform regarding land use must be a priority of these losses are to be counteracted.
