From 1994 to 2014, we recorded data annually on disease occurrence, causal pathogens, species and age classes affected, total number of breeding pairs of cormorants on the colony site, and other biological parameters. A mathematical model of pathogen transmission was constructed to assess the potential importance of transmission parameters and to test a hypothesis regarding the potential effect of the observed progressive loss of nest trees and the consequent shift from tree-nesting to ground-nesting behavior. The model indicated that juveniles from ground nests were 14 times more likely to die from epidemic disease (50.14% mortality) than were juveniles from nests in trees (3.57% mortality). Additive disease-related mortality of juvenile cormorants in the observed range of 40\u201360% would reduce a closed cormorant population over time. There was no directional change in the colony population during the study period, suggesting that immigration had compensated for disease-related mortality. Our results highlight the preeminent influence of environmental factors on pathogen transmission and the value of long-term data sets.<\/jats:p>","DOI":"10.7589\/jwd-d-20-00213","type":"journal-article","created":{"date-parts":[[2021,10,11]],"date-time":"2021-10-11T01:32:54Z","timestamp":1633915974000},"page":"773-783","source":"Crossref","is-referenced-by-count":5,"title":["REVENGE OF THE TREES: ENVIRONMENTAL DETERMINANTS AND POPULATION EFFECTS OF INFECTIOUS DISEASE OUTBREAKS ON A BREEDING COLONY OF DOUBLE-CRESTED CORMORANTS (PHALACROCORAX AURITUS) OVER A PERIOD OF 21 YEARS"],"prefix":"10.7589","volume":"57","author":[{"given":"Frederick A.","family":"Leighton","sequence":"first","affiliation":[{"name":"Canadian Wildlife Health Cooperative, Western College of Veterinary Medicine, University of Saskatchewan, 52 Campus Drive, Saskatoon, S7N 5B4 Saskatchewan, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick A.","family":"Leighton","sequence":"additional","affiliation":[{"name":"Epidemiology of Zoonoses and Public Health Research Group (GREZOSP), Faculty of Veterinary Medicine, Universit\u00e9 de Montr\u00e9al, 3200, rue Sicotte, Saint-Hyacinthe (Qu\u00e9bec), J2S 2M2 Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Wood","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, Western College of Veterinary Medicine, University of Saskatchewan, 52 Campus Drive, Saskatoon, S7N 5B4 Saskatchewan, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thijs","family":"Kuiken","sequence":"additional","affiliation":[{"name":"Department of Viroscience, Erasmus University Medical Centre, PO Box 2040, 3000 CA Rotterdam, the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4415","reference":[{"key":"25","unstructured":"G Wobeser, FA Leighton, R Norman, et al.  \"Can Vet J.\"  34, \"Newcastle disease in wild water birds in western Canada, 1990.\" 353 (1993)"},{"key":"9","doi-asserted-by":"crossref","unstructured":"T.
