計畫資料

Rising river temperatures are increasingly exposing cold adapted species to heat stress and predation stress caused by warm-adapted aquatic invasive predators. To cope with heat stress during high temperature events, prey fish - such as young salmonids, thermoregulate in cold-water refugia. Given the overlapping distribution between salmonids and aquatic invasive species it is unclear if invasive predators are using cold-water refugia as foraging patches and how this would affect refugia use by salmonids. One approach to understand such effects is by integrating monitoring and tracking technology, as it provides insight into fine-scale behaviours during habitat use. However, employing this approach is difficult as multiple devices exist, and each one is better suited under different environmental conditions. Therefore, in my first data chapter I will describe how monitoring and tracking devices were previously employed across different objectives and environments. In my second data chapter, I will examine the cold-water refugia use by smallmouth bass (Micropterus dolomieu), an invasive predator in North America, and the subsequent response of juvenile Atlantic salmon (Salmo salar), in the Margaree River, Nova Scotia. Using acoustic telemetry and underwater video cameras, I will be examining habitat use of both species in one cold-water refuge sites. I expect that thermal refugia provides a predation opportunity for smallmouth bass, and in response, juvenile salmon will behaviourally trade off between thermoregulation and predator avoidance. Investigating the use of technoscience in aquatic ecosystems will guide researchers in more effectively employing such techniques in their own studies. Additionally, investigating the impact of aquatic invasive species on critical habitats to salmonids will inform more effective and resilient management of invasive species and protection and enhancement of thermal refugia as climate change persists.
