Wetland hydrologic dynamics and duck productivity are declining in the Prairie Pothole Region, and they are linked

Environmental and Sustainability Indicators
The Prairie Pothole Region (PPR) of North America is a globally important area hosting >50 % of North America’s breeding ducks. Ducks in the PPR depend on wetlands and grasslands which have experienced accelerated losses in extent and quality due to ...

Band Wear and Effects on Recovery and Survival Estimates of Diving Ducks

Wildlife Society Bulletin, 2020
Wildlife biologists commonly use marked individuals to estimate population size and vital rates. If markers are lost or become too illegible to be reported (which we define as functional loss), population size and vital rates derived from marked ...

Assessment on level of selected heavy metals in Nile Tilapia and Barbus fish species and water samples from the Southern parts of Lake Tana, Ethiopia

Scientific African, 2020
Metals released in to the aquatic ecosystem may be accumulated in aquatic organisms through the cumulative effects of bio-concentration, and bioaccumulation via the food chain pathway and become toxic when concentration reaches a considerably high level.

Developing a photography‐based harvest survey to estimate age and subspecies composition of midcontinent sandhill cranes

Wildlife Society Bulletin
Midcontinent sandhill cranes (Antigone canadensis) are managed as a single population, but hunting regulations are structured so harvest is targeted towards the more numerous lesser sandhill cranes (A. c. canadensis).

Landowner and biologist perceptions of game bird predators and management

Wildlife Society Bulletin, 2023
Nest survival has been identified as one of the most influential vital rates causing population change in game birds, and depredation, often influenced by habitat loss and fragmentation, is the primary cause of nest failure of upland game birds.
