Biogeography and predictive niche-modeling of invasive or non-native North American species of dayflower (Commelina, Commelinaceae).
There are nine species of Commelina in the Flora of North America, three of which are native, and six of which are non-native. Of the non-native species, two or three are considered invasive. The objective of this study was to identify the geographic origins, estimate climatic envelopes, and determine rates of biogeographic spread of invasive Commelina species within North America. We used innovative georeferencing software and GIS programs to model species ranges and make predictions about states and counties open to invasion. The result of this study may facilitate efforts to mitigate the spread of invasive species, which generally are regarded as one of the main reasons for loss in biodiversity and crop yields. Invasive species impact nearly half of the species listed as Threatened or Endangered under the Endangered Species Act. According to the USDA, the U.S. spends 120 billion annually on the control and impact of invasive species.
