Differences of public and scientific attention to plant speciation and extinction. The public is more concerned with plant extinction (a), whereas scientists have a greater interest in plant speciation (b). We used Google Ngram’s millions of English-language books [37] to quantify the public attention on “plant speciation” and “plant extinction” during 1980–2008. The cumulative word frequency is 6.4 × 10− 8 and 8.0 × 10− 8 for plant speciation and extinction, respectively. We searched the core database of Web of Science for the publication of “plant speciation” and “plant extinction” during 1980–2018 to illustrate the academic concerns. The cumulative published papers are 6946 and 6651 on “plant speciation” and “plant extinction”, respectively. The searched research field was plant science, and the selected 10 journals of evolution and ecology: Annual Review of Ecology Evolution and Systematics, Biology Letters, BMC Evolutionary Biology, Evolution, Evolutionary Applications, Evolutionary Biology, Evolutionary Ecology, Proceedings of the Royal Society B-Biological Sciences, Systematic Botany, and Trends in Ecology & Evolution
