Can the invaded range of a species be predicted sufficiently using only native-range data? Lehmann lovegrass (Eragrostis lehmanniana) in the southwestern United States

摘要: Abstract Predictions of species invasions are often made using information from their native ranges. Acquisition native-range can be very costly and time-consuming in some cases may not reflect conditions the invaded range. Using range enable much faster modeling at finer geographic resolutions than a species’ We used confirmed presence points range, southern Africa, southwestern United States, to predict potential distribution perennial bunchgrass Eragrostis lehmanniana Nees, (Lehmann lovegrass), its States. The two models showed strong agreement for area encompassed by offered insight into overlapping but slightly different ecological niche occupied introduced grass Regions outside scope inference less between models. E. was selected via seeding trials before being planted States therefore represents an isolated genotype population. Models built provide how is expressed on landscape considers influences present created locations both ranges lead more complete understanding spread, especially case anthropogenic selection.
