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

  • Ecology
  • Botany
  • Genetics

Mark R. Macnair spends much of his time researching Genetics, Botany, Metal, Synteny and Quantitative trait locus. His Genetics study combines topics in areas such as Evolutionary biology and Reproductive isolation. His study in Synteny is interdisciplinary in nature, drawing from both Candidate gene, Arabidopsis and Comparative genomics, Genomics.

His study connects Arabidopsis lyrata and Quantitative trait locus.
