From: Species distribution models throughout the invasion history of Palmer amaranth predict regions at risk of future invasion and reveal challenges with modeling rapidly shifting geographic ranges

Figure 4

Sequential historical models and time series analyses of A. palmeri. Panels depict models built with occurrence records that include data up to a given year (1970, 1990, 2010). Projections on the top row (panels A–D) were built with CliMond environmental variables and those on the second row (panels E–H) were built with PRISM environmental variables. Occurrence records used to build models are in red (A–D; CliMond) or yellow (E–H; PRISM) all other occurrences are in gray. The complementary log-log predicted probability for each raster cell is indicated by the color corresponding the bars to the right of the panels. Metrics of range expansion are on the bottom row. The panel I depicts the accumulation of records through time. The panel J depicts the change in Area of Occupancy (measured in number of 30 arcsecond grid cells) over time. Lastly, the panel K depicts the average predicted probability over all grid cells for models built at each time period.
