- Prior to FY 2016, expenditures for natural resources and conservation, materials science, anthropology, and industrial and manufacturing engineering were not collected separately. R&D expenditures in agricultural sciences decreased in FY 2016 because a number of disciplines previously reported in that field are now reported separately under natural resources and conservation.
