Crayfish invasions at ICAIS 2016

by Jaime Grimm

With the generous support of the QCBS, I was able to attend the 19th International Conference on Aquatic Invasive Species (ICAIS) this April, in Winnipeg. I presented my research to an audience of experts in the field, many of whom were familiar with my model species and the experimental techniques I have been implementing, and therefore able to provide extremely valuable feedback.

The rusty crayfish (Orconectes rusticus) is a prolific invader in eastern Canada

My research uses functional response (FR) analyses to assess and compare the per capita effect of invasive species. Specifically, I conduct FR experiments in the lab to try to quantify the impact potential of invasive crayfishes in Canada and Europe. In previous studies, this technique has shown promising results for implementation in the risk assessment of invasive populations, and may lead to more successful management of incoming invaders.

At ICAIS, I presented a research proposal discussing methods I’ve used in preliminary experiments, and the value of working with invasive crayfishes as a model system. This conference allowed me to connect with experts in the FR technique and solidify plans for future collaborations. In addition, I gained valuable feedback on parts of my methodology that I will be able to apply to future experiments that I plan to conduct this summer in the UK. (My collaboration in the UK is also partially funded by the QCBS, so stay tuned for more information!)
