areas, and the animals do not ingest the weeds, which further promotes
their invasion.
Based on the results of the IPCC studies, in the world’s grasslands that are
expected to receive an increase in precipitation, such as the western United
States, these areas may not be faced with the drying out resulting from lack
of water and rising temperatures, but these areas may suffer from accelerated
nutrient cycling, which in turn could encourage the spread of more invasive
species. In the hot desert grasslands (such as in Australia, in the Sonoran
and Chihuahua deserts of Mexico, and in the United States), GCMs predict
an increase in the frequency of intense rainfall and ash oods. These areas
are expected to have ...
