Invasive species adversely affect biodiversity, but little is known about how ecologically similar invaders interact. Such intraguild interactions may drive non‐native community dynamics and their broader impacts on biodiversity. In native systems, intraguild interactions are widespread strong eco‐evolutionary pressures; understanding whether similar patterns occur among invaders is key to predicting invasion outcomes. We inve...

The success of non‐native species depends on their ability to find food, which may ultimately lead to competition with native species and contribute to biodiversity loss in invaded ecosystems. Understanding which food resources are consumed is therefore crucial for evaluating how non‐native species mechanistically fit into native biological communities. Non‐native species may be predators or competitors of native species or ma...
