Age-specific survival and recruitment of piping plovers Charadrius melodus in the Great Lakes region
Sarah P. Saunders, Auteur ; Todd W. Arnold, Auteur ; Erin A. Roche, Auteur ; Francesca J. Cuthbert, AuteurJuvenile survival and age at first breeding (i.e. recruitment) are critical parameters affecting population dynamics in birds, but high levels of natal dispersal preclude measurement of these variables in most species. We used multi-state captur[...]
