Estimating abundance of harvested populations at the management unit scale Open
Management of harvested populations relies on accurate assessment of abundance within management units to reevaluate and set harvest regulations. Several statistical approaches use readily available age-at-harvest data to estimate populati…

Wintering mallard survival is unaffected by brief anthropogenic disturbance on protected areas Open
Human activities in natural areas can impose both lethal and non‐lethal impacts on animals. Furthermore, anthropogenic disturbance is analogous to predation risk and can cause animals to adjust their behaviors to avoid humans. Quantifying …

Mallard Hybridization With Domesticated Lineages Alters Spring Migration Behavior and Timing Open
Introgressive hybridization, the interbreeding and gene flow between different species, has become increasingly common in the Anthropocene, where human‐induced ecological changes and the introduction of captively reared individuals are inc…

Mallard response to experimental human disturbance on sanctuary areas is mediated by hunting Open
Wildlife managers often provide spatial sanctuaries for wildlife to escape both lethal (e.g. hunting) and non‐lethal (e.g. non‐consumptive recreation) human disturbance. However, as societal interest in outdoor recreation continues to clim…

Comparing winter distribution and harvest rates of transmitter‐marked and banded‐only mallards in western Tennessee Open
The miniaturization of Global Positioning Systems (GPS) transmitters is providing insights into the ecology and management of migratory bird species at biologically‐relevant spatial scales. However, transmitters and their attachment method…

Proximity among protected area networks promotes functional connectivity for wintering waterfowl Open
The equilibrium theorem provided a fundamental framework for understanding species' distributions and movement in fragmented ecosystems. Wetland-dependent avian species are model organisms to test insular predictions within protected area …

Caught out in the cold: <i>Anas platyrhynchos</i> (Mallard) survival decreased during an extreme climatic event Open
Extreme climatic events (ECEs) can have profound impacts on individual fitness, affecting survival directly or indirectly. Late winter ECEs may be especially detrimental to fitness due to limited food resources and increased energetic requ…

A rapid monitoring protocol to estimate unharvested corn biomass in waterfowl impoundments Open
Conservation planners use bioenergetic models to develop habitat objectives that satisfy energetic demands of waterfowl during nonbreeding periods. In turn, natural resource managers should estimate yield and availability of natural and cu…

Human access constrains optimal foraging and habitat availability in an avian generalist Open
Animals balance costs of antipredator behaviors with resource acquisition to minimize hunting and other mortality risks and maximize their physiological condition. This inherent trade‐off between forage abundance, its quality, and mortalit…
View article: Hunting constrains wintering mallard response to habitat and environmental conditions
Hunting constrains wintering mallard response to habitat and environmental conditions Open
The spatiotemporal allocation of activity is fundamental to how organisms balance energetic intake and predation risk. Activity patterns fluctuate daily and seasonally, and they are proximately affected by exogenous and endogenous conditio…

North American wintering mallards infected with highly pathogenic avian influenza show few signs of altered local or migratory movements Open
Avian influenza viruses pose a threat to wildlife and livestock health. The emergence of highly pathogenic avian influenza (HPAI) in wild birds and poultry in North America in late 2021 was the first such outbreak since 2015 and the larges…

Citizen science reveals waterfowl responses to extreme winter weather Open
Global climate change is increasing the frequency and severity of extreme climatic events (ECEs) which may be especially detrimental during late‐winter when many species are surviving on scarce resources. However, monitoring animal populat…
View article: Evidence of economical territory selection in a cooperative carnivore
Evidence of economical territory selection in a cooperative carnivore Open
As an outcome of natural selection, animals are probably adapted to select territories economically by maximizing benefits and minimizing costs of territory ownership. Theory and empirical precedent indicate that a primary benefit of many …

ADAPTIVE HARVEST MANAGEMENT OF WOLVES: THE ROLE OF RECRUITMENT AND HIERARCHICAL DEMOGRAPHY IN POPULATION DYNAMICS OF A SOCIAL CARNIVORE Open
Regulated public harvest became an important management tool following recovery of gray wolves (Canis lupus) in the U.S. Northern Rocky Mountains. Decisions on harvest regulations, however, can be contentious due to conflicting stakeholder…

Explicitly reporting tests of hypotheses improves communication of science Open
Hypothesis testing is fundamental to producing the rigorous biological inferences needed to reliably inform wildlife management (Platt 1964, Romesburg 1981, Williams 1997, Sells et al. 2018). Hypothesis testing results in inferences that h…

Increased scientific rigor will improve reliability of research and effectiveness of management Open
Rigorous science that produces reliable knowledge is critical to wildlife management because it increases accurate understanding of the natural world and informs management decisions effectively. Application of a rigorous scientific method…
