Mallard migration and regional movement timing, distance, and direction data, 2018–2020
The mallard (Anas platyrhynchos) is an abundant and wide-spread duck species that exhibits considerable variation in migratory behavior due to a relatively large body size and behavioral plasticity in habitat use. Understanding migration and other movements of mallards has societal interest in a wildlife management context because mallards are a preferred species of waterfowl by hunters and have t
Factors influencing autumn–winter movements of midcontinent Mallards and consequences for harvest and habitat management
Annual phenology and distributions of migratory wildlife have been noticeably influenced by climate change, leading to concerns about sustainable populations. Recent studies exploring conditions influencing autumn migration departure have provided conflicting insights regarding factors influencing the movements of Mallards (Anas platyrhynchos), a popular game species. We determined factors affecti

The local responses of aquatic ecosystems to adjacent grassland conservation: Can streams of dreams exist in a degraded riverscape?
Landscape homogenization and the removal of riparian areas have altered stream ecosystems worldwide. Numerous conservation programmes attempt to improve water quality and increase instream habitat heterogeneity to elicit desired biological responses. However, the effectiveness of many conservation efforts on isolated stream fragments remains unknown, especially in grassland regions.The effects of

Extreme climatic variability during migration invokes physiological and dietary plasticity among spring migrating ducks
Environmental stochasticity encountered during migration can have negative consequences for individuals and population demographics through direct reductions in survival or cross-seasonal impacts. We took advantage of substantial interannual variation in spring migration conditions over a 4 year field study to examine physiological and dietary variation among two species of migrant ducks. We colle

Application strategy for an anthraquinone-based repellent and the protection of soybeans from Canada goose depredation
Agricultural crops can sustain extensive damage caused by Canada geese (Branta canadensis) when these crops are planted near wetlands or brood-rearing sites. From 2000 to 2015, South Dakota Game, Fish and Parks spent >$5.6 million to manage damages caused by Canada geese to agricultural crops (primarily soybeans) in South Dakota, USA. For the purpose of developing a repellent application strategy
