Description

This is the OBIS extraction of the Ocean Tracking Network and University of Windsor (UWindsor) Using biotelemetry and underwater video within thermal refugia, consisting of the release tagging metadata, i.e. the location and date when the tagged animal was released, and summarized detection events of tagged individuals. 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.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 10,924 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Title Risky Refugia? Using biotelemetry and underwater video to quantify effects of Aquatic Invasive Species on juvenile Atlantic salmon (Salmo salmar) within thermal refugia
Funding 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).
Study Area Description No study area description for this project was provided to OTN for publication.
Design Description 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.

Acoustic tags released.

Study Extent Program started 2023-09-01 and ran until None
Quality Control 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
