    Quach KT, & Chalasani SH (2020). Intraguild predation between Pristionchus pacificus and Caenorhabditis elegans: a complex interaction with the potential for aggressive behaviour. J Neurogenet, 1-16. doi:10.1080/01677063.2020.1833004

    The related nematodes <i>Pristionchus pacificus</i> and <i>Caenorhabditis elegans</i> both eat bacteria for nutrition and are therefore competitors when they exploit the same bacterial resource. In addition to competing with each other, <i>P. pacificus</i> is a predator of <i>C. elegans</i> larval prey. These two relationships together form intraguild predation, which is the killing and sometimes eating of potential competitors. In killing <i>C. elegans</i>, the intraguild predator <i>P. pacificus</i> may achieve dual benefits of immediate nutrition and reduced competition for bacteria. Recent studies of <i>P. pacificus</i> have characterized many aspects of its predatory biting behaviour as well as underlying molecular and genetic mechanisms. However, little has been explored regarding the potentially competitive aspect of <i>P. pacificus</i> biting <i>C. elegans</i>. Moreover, aggression may also be implicated if <i>P. pacificus</i> intentionally bites <i>C. elegans</i> with the goal of reducing competition for bacteria. The aim of this review is to broadly outline how aggression, predation, and intraguild predation relate to each other, as well as how these concepts may be applied to future studies of <i>P. pacificus</i> in its interactions with <i>C. elegans</i>.
