Fish carcasses have been shown to affect juvenile salmon growth in many systems, but carcasses likely also alter behavioral and dispersal response of hatchery-origin young-of-the-year salmon. We tested the social and emigration response of subyearling chinook salmon to carcasses of Pacific lamprey or rainbow trout using semi-open flow-through mesocosm experiments. We expected the presence of carcasses to increase salmon growth and density while decreasing intraspecific aggression and downstream emigration compared to controls without carcasses. Consistent with expectations, salmon emigrated at lower rates when carcasses were present, resulting in significantly higher holding densities. Contrary to our expectations and results from previous studies, we did not detect differences in growth rate of juvenile salmon among treatments. Our findings suggest that indirect responses of consumers to concentrated resources may have measurable effects on density mediated by movement behaviors. Differences in lamprey and trout decomposition also suggest that carcass traits mediate the behavioral responses of consumers and incorporation of carcass subsidies into food webs.","url":"https:\/\/data.nkn.uidaho.edu\/dataset\/data-fish-carcasses-alter-subyearling-chinook-salmon-dispersal-behavior-and-density-not","state":"Active","log_message":"Update to resource Data and Analysis-Dunkle et al. 2021","private":true,"revision_timestamp":"Mon, 07\/19\/2021 - 09:53","metadata_created":"Thu, 07\/15\/2021 - 11:50","metadata_modified":"Mon, 07\/19\/2021 - 09:53","creator_user_id":"6cc16f2c-77c2-4d12-ac06-56bbb86b535b","type":"Dataset","resources":[{"id":"282c1308-1d19-4af1-b9c5-4a7791b1b441","revision_id":"","url":"https:\/\/data.nkn.uidaho.edu\/sites\/default\/files\/Dunkle_etal_2021_0.zip","description":"All necessary data (.csv) and code (.rmd) for the analyses found in the manuscript entitled \u0022Fish carcasses alter subyearling Chinook salmon dispersal behavior and density but not growth in experimental mesocosms\u0022 (Dunkle et al.)","format":"zip","state":"Active","revision_timestamp":"Mon, 07\/19\/2021 - 09:53","name":"Data and Analysis-Dunkle et al. 2021","mimetype":"application\/zip","size":"437.98 KB","created":"Thu, 07\/15\/2021 - 12:37","resource_group_id":"89a02fc8-c98e-44bb-9d3e-2d3d0849fbca","last_modified":"Date changed Mon, 07\/19\/2021 - 09:53"}],"tags":[{"id":"425f965a-f839-486d-be20-95827298c8c0","vocabulary_id":"2","name":"ecology"},{"id":"21f8e9cf-adf4-4741-a1a7-2eab6a3526c5","vocabulary_id":"2","name":"fisheries science"},{"id":"23367871-1192-45d1-bcc3-111fdd55221a","vocabulary_id":"2","name":"freshwater biology"},{"id":"71776a1d-21a7-4d03-820c-e8853dfca9cd","vocabulary_id":"2","name":"chinook salmon"},{"id":"86537a2b-f5f3-4200-9273-30193c508c4d","vocabulary_id":"2","name":"emigration"},{"id":"624cc7e2-f393-4cae-8d31-d266e95335d7","vocabulary_id":"2","name":"density-dependence"},{"id":"e9fea701-4798-4aa4-988d-0126e2766ec3","vocabulary_id":"2","name":"food webs"},{"id":"145796a1-d727-4a1d-86d4-574b5bb3ed7e","vocabulary_id":"2","name":"marine-derived nutrients"}],"groups":[{"description":"\u003Cp\u003ESince 1889, the University of Idaho has provided motivated students with a transformative higher education experience that prepares them to solve real-world problems and achieve success in their lives and careers.\u003C\/p\u003E\n\u003Cp\u003ELearn more at \u003Ca href=\u0022https:\/\/www.uidaho.edu\u0022\u003Ehttps:\/\/www.uidaho.edu\u003C\/a\u003E\u003C\/p\u003E\n","id":"89a02fc8-c98e-44bb-9d3e-2d3d0849fbca","image_display_url":"https:\/\/data.nkn.uidaho.edu\/sites\/default\/files\/UI_Main_horizontal_4c.jpg","title":"University of Idaho","name":"group\/university-idaho"}]}]} Error | RCDS Data Repository
