Study finds small mammals aid expansion of warm-climate trees


JULY 19, 2019

A new study by Alessio Mortelliti, an assistant professor of wildlife habitat ecology at the University of Maine, finds small mammals could affect whether trees spread to new areas in a warming climate.
Mortelliti's research, which was published in the journal Oikos, looks at the behavior of small forest mammals that eat acorns and other tree seeds.
By choosing certain seeds and rejecting others, the animals can alter the trees that make up a forest, according to a Second Century Stewardship news release.
If they eat all the seeds in their territory, those seeds can't grow into new trees. Seeds that are carried away, stored for later, and then forgotten can germinate away from their parent tree, the release states.
