Data from: Biomass responses of widely and less-widely naturalized alien plants to artificial light at night

Artificial light at night has rapidly increased during the last century, and could potentially affect many ecological processes, from individuals via communities to entire ecosystems. Recent research has shown that artificial light at night may not only affect the behavior of animals but also growth of plants and vegetation composition. However, it is not known yet whether artificial light at night may also affect other global change components such as plant invasions.  

Here, we tested how naturalized alien plants respond to artificial light at night, and particularly whether widely naturalized species differ from less-widely naturalized species in their response to artificial light at night. We grew nine taxonomically related pairs of widely naturalized and less-widely naturalized species alone and in competition, with native plants with and without artificial light at night.

We found that in the competition treatment, artificial light at night significantly increased the total ...
