If readers are interested in the source dataset they may also inquire with the project PIs as listed here or on the OTN web site (https://members.oceantrack.org/project?ccode=V2LSWMA). Abstract: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.

+1 (902) 494-4101 otndc@dal.ca http://members.oceantrack.org This resource was created by the Ocean Tracking Network Data Centre as a summarized representation of animal presence determined by electronic tagging efforts. Darwin Core (DwC) records were extracted from the OTN database and filtered and summarized according to international agreed-upon standards. Program started 2023-09-01 and ran until None Acoustic tags released. OTN species names are verified using the World Register of Marine Species (WoRMS). If species names on new data cannot be verified against (a) known valid names in OTN, and/or (b) WoRMs the Data Provider will be notified so they can check they are correct. Names that cannot be placed after checking with WoRMS are, where possible, placed on the basis of other authoritative sources, such as the Fishbase or ITIS; and once completely verified a request will be sent to WoRMS for addition of the verified species name. http://members.oceantrack.org/data/discovery/byspecies Fielding Montgomery 0000-0003-0717-4858 principalInvestigator Christina Semeniuk 0000-0001-5115-9853 principalInvestigator Kristen Cyr 0009-0004-2117-279X principalInvestigator Rising river temperatures are increasingly exposing cold adapted species to heat stress and predation stress caused by warm-adapted aquatic invasive predators.

No funding information for this project was provided to OTN for publication. OTN is a research and technology development initiative headquartered at Dalhousie University, in Halifax, Nova Scotia. OTN is funded by the Canada Foundation for Innovation (CFI) and is grateful to have once received funding from the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Social Sciences and Engineering Research Council of Canada (SSHRC). No study area description for this project was provided to OTN for publication. A wide range of aquatic species are tagged with small electronic transmitters, surgically implanted or attached externally, which can operate for up to 20 years. Acoustic receivers arranged in line on the ocean floor as well as attached to buoys, gliders and large animals (e.g. grey seals) pick up the coded acoustic signals from these tags identifying each tagged sea creature that passes within half a kilometer of the receiver. Data collected by these listening stations are subsequently uploaded to one of many compatible data nodes, adding to the reach of an intercompatible network of networks designed and maintained by the Ocean Tracking Network, producing current and reliable records for every part of the globe. Certain classes of electronic tags and listening equipment (receivers) may also be outfitted or co-located with sensors to measure the ocean's temperature, depth, salinity, currents, chemistry, and other properties. 2025-03-31T00:00:00.000+00:00 dataset This will need to be revised as we continue on working on this project..
