We may have lots of information on the native ecology of a species, but not on it within its invaded range.
The two models showed strong agreement for the area encompassed by the presence points in the invaded range, and offered insight into the overlapping but slightly different ecological niche occupied by the introduced grass in the invaded range.
Acquisition of native-range information can be very costly and time-consuming and in some cases may not reflect conditions in the invaded range.
Using information from the invaded range can enable much faster modeling at finer geographic resolutions than using information from a species' native range.
We used confirmed presence points from the native range, southern Africa, and the invaded range, the southwestern United States, to predict the potential distribution of the perennial bunchgrass Eragrostis lehmanniana Nees, (Lehmann lovegrass), in its invaded range in the United States.
Our study underlines how this exotic parasitic wasp effectively suppresses a globally-important insect pest in its newly invaded range, thus providing cost-free, environmentally-sound and lasting control across the developing-world tropics.
Models built using confirmed presence points from the invaded range can provide insight into how the selected genotype is expressed on the landscape and considers influences not present in the native range.
Of 19 Drosophila species tested, DNA from one species in the invaded range of D. suzukii was amplified, but it was distinguishable from D. suzukii due to different amplicon melting temperatures.
Once established, L. humile causes the decrease of populations of many organisms in its invaded range, including plants [2], other arthropods [3], [4] and even vertebrates [5].
In invasive species, at least some of the traits present in the invaded range but absent in the native range represent microevolutionary responses to novel environments.
If the higher parameter estimates represent realistic conditions for lionfish in the invaded range, high levels of sustained fishing mortality will be required to cause overfishing.
