Animal movement and associated infectious disease risk in a metapopulation Open
Animal movements among habitat patches or populations are important for maintaining long-term genetic and demographic viability, but connectivity may also facilitate disease spread and persistence. Understanding factors that influence anim…

Reimmunization intervals for application of GnRH immunocontraceptive vaccine (GonaCon-Equine) in free-roaming horses (Equus ferus caballus) using syringe darts Open
Management of overabundant free-roaming horse (Equus ferus caballus) populations has become a divisive and challenging effort for natural resource managers worldwide. Controlling these populations requires land managers to balance socio-po…

More than an anthropogenic phenomenon: Antimicrobial resistance in ungulates from natural and agricultural environments Open
Widely considered an anthropogenic phenomenon, antimicrobial resistance (AMR) is a naturally occurring mechanism that microorganisms use to gain competitive advantage. AMR represents a significant threat to public health and has generated …

Spatial network clustering reveals elk population structure and local variation in prevalence of chronic wasting disease Open
Spatial organization plays prominent roles in disease transmission, genetics, and demography of wildlife populations and is therefore an important consideration not only for wildlife management, but also for inference about populations and…

Reimmunization increases contraceptive effectiveness of gonadotropin-releasing hormone vaccine (GonaCon-Equine) in free-ranging horses (Equus caballus): Limitations and side effects Open
Wildlife and humans are increasingly competing for resources worldwide, and a diverse, innovative, and effective set of management tools is needed. Controlling abundance of wildlife species that are simultaneously protected, abundant, comp…

Applying a Bayesian weighted surveillance approach to detect chronic wasting disease in white‐tailed deer Open
Surveillance is critical for early detection of emerging and re‐emerging infectious diseases. Weighted surveillance leverages heterogeneity in infection risk to increase sampling efficiency. Here, we apply a Bayesian approach to estimate w…

Pathogen-mediated selection in free-ranging elk populations infected by chronic wasting disease Open
Significance Chronic wasting disease (CWD) is a fatal neurodegenerative disease that can cause declines in deer and elk populations. Theoretical work suggests elk will adapt to the disease by favoring a naturally occurring but underreprese…

Using decision analysis to support proactive management of emerging infectious wildlife diseases Open
Despite calls for improved responses to emerging infectious diseases in wildlife, management is seldom considered until a disease has been detected in affected populations. Reactive approaches may limit the potential for control and increa…
