Competition mechanism of introduced and native ants in China

In the article “Comparing mechanisms of competition among introduced and resident ants in China: from behavior to trophic position (Hymenoptera: Formicidae)” published in Myrmecological News, Lei Nie, Meihong Ni, Dongdong Ning, Hao Ran, Babar Hassan, and Yijuan Xu perform, among others, aggression assays and infer trophic positions of several native and invasive ant species. Their results suggest species differences in behavioral and trophic interactions between invasive and resident ants. Here, Lei Nie shares some pictures and videos of their research.
