His Carbon dioxide study combines topics from a wide range of disciplines, such as Toxicology, Per capita and Horticulture. His studies deal with areas such as Panicle and Crop as well as Cultivar. The study incorporates disciplines such as Monoculture, Avena fatua, Avena and Competition in addition to Biomass.

Between 2013 and 2021, his most popular works were:

  • Carbon dioxide (CO2) levels this century will alter the protein, micronutrients, and vitamin content of rice grains with potential health consequences for the poorest rice-dependent countries. (104 citations)
  • Rising atmospheric CO2 is reducing the protein concentration of a floral pollen source essential for North American bees. (39 citations)
  • Cheatgrass is favored by warming but not CO2 enrichment in a semi‐arid grassland (37 citations)

In his most recent research, the most cited papers focused on:

  • Ecology
  • Botany
  • Agriculture

Lewis H. Ziska mostly deals with Carbon dioxide, Carbon dioxide in Earth's atmosphere, Agronomy, Biomass and Photosynthetic acclimation. He combines subjects such as Taxon, Solidago altissima, Horticulture and Solidago canadensis with his study of Carbon dioxide. His Carbon dioxide in Earth's atmosphere research is multidisciplinary, incorporating elements of Pollen, Botany, Toxicology, Crop productivity and Weed control.

He studies Agronomy, focusing on Weed in particular. His Biomass research is multidisciplinary, incorporating perspectives in Nutrient and Per capita. His Photosynthetic acclimation research is multidisciplinary, relying on both Photosynthetic capacity, Panicle and Cultivar.
