Biomass#

Biomass of insects caught in malaise traps over 96 unique location-year pairs, together with date and general description of type of nature area.

From the authors: “Current data suggest an overall pattern of decline in insect diversity and abundance. Loss of insects is certain to have adverse effects on ecosystem functioning, as insects play a central role in a variety of processes, including pollination, herbivory and detrivory, nutrient cycling and providing a food source for higher trophic levels such as birds, mammals and amphibians. For example, 80 percent of wild plants are estimated to depend on insects for pollination, while 60 percent of birds rely on insects as a food source.”

Initialization#
