Todd W. Arnold, Alan D. Afton, Michael J. Anteau, David N. Koons, Chris A. Nicolai
2017, Journal of Wildlife Management (81) 1142-1148
We recently analyzed long-term (1951–2011) continental band-recovery data from lesser scaup (Aythya affinis) and demonstrated that harvest rates declined through time, but annual survival rates exhibited no such trends; moreover, annual harvest and survival rates were uncorrelated for all age-sex classes. We therefore concluded that declining fecundity was most likely...
