Foraging activity of native ants on trees in forest fragments colonized by the invasive ant Lasius neglectus

Our aim was to investigate the foraging activity of native ants on tree trunks in accordance with their location in forest fragments and the presence or absence of the invasive ant Lasius neglectus. Trees were categorized as isolated, edge, or core trees according to their location in forest fragmen...

Trees were categorized as isolated, edge, or core trees according to their location in forest fragments. In invaded fragments, Lasius neglectus had the highest spatial-temporal tree visitation.
