Identifying the demographic parameters (eg, reproduction, survival, dispersal) that most
influence population dynamics can increase conservation effectiveness and enhance …

The process of setting waterfowl hunting regulations is conducted annually in the United
States (US; Blohm 1989) and involves a number of meetings where the status of waterfowl is …

Management of lesser scaup (Aythya affinis) has been hindered by access to reliable data
on population trajectories and vital rates. We conducted a Bayesian analysis of historical …

Managing sustainable harvest of wildlife populations requires regular collection of
demographic data and robust estimates of demographic parameters. Estimates can then be …

Context North American waterfowl managers have long suspected that waterfowl harvest
estimates derived from national harvest surveys in the USA are biased high. Survey bias can …

Potential bias in breeding population estimates of certain duck species from the Waterfowl
Breeding Population and Habitat Survey (WBPHS) has been a concern for decades. The …

A common goal in ecology and wildlife management is to determine the causes of variation
in population dynamics over long periods of time and across large spatial scales. Many …

Estimates of band reporting probabilities are used for managing North American waterfowl
to convert band recovery probabilities into harvest probabilities, which are used to set …

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 …

Concerns about declines in the abundance of lesser scaup (Aythya affinis) have promoted a
number of analyses to understand reasons for this decline. Unfortunately, most of these …
