      Wild fish are confronting changing pathogen dynamics arising from anthropogenic disturbance and climate change. Pathogens can influence animal behaviour and life histories, yet there are little such data from fish in the ...

    • One Hundred Pressing Questions on the Future of Global Fish Migration Science, Conservation, and Policy 

      Lennox, Robert J.; Paukert, Craig P.; Aarestrup, Kim; Auger-Méthé, Marie; Baumgartner, Lee; Birnie-Gauvin, Kim; Bøe, Kristin; Brink, Kerry; Brownscombe, Jacob W.; Chen, Yushun; Davidsen, Jan Grimsrud; Eliason, Erika J.; Filous, Alexander; Gillanders, Bronwyn M.; Helland, Ingeborg Palm; Horodysky, Andrij Z.; Januchowski-Hartley, Stephanie R.; Lowerre-Barbieri, Susan K.; Lucas, Martyn C.; Martins, Eduardo G.; Murchie, Karen J.; Pompeu, Paulo S.; Power, Michael; Raghavan, Rajeev; Rahel, Frank J.; Secor, David; Thiem, Jason D.; Thorstad, Eva Bonsak; Ueda, Hiroshi; Whoriskey, Frederick G.; Cooke, Steven J. (Journal article; Peer reviewed, 2019)

    • The risk of individual fish being captured multiple times in a catch and release fishery
