Wood duck brood movements and habitat use on prairie rivers in South Dakota

Article Abstract:

The brood movements of wood duck are little understood, particularly in the prairie habitats of the Central Flyway where populations have been increasing. A new study investigates the habitat use and movements of wood duck on two prairie rivers with different landscapes. The study shows that wood duck broods on prairie rivers can benefit from corridors allowing them to move to brood areas via water and landowners should be encouraged to keep riparian vegetation along rivers and emergent vegetation beside seasonal streams to give a brood-rearing habitat in both wet and dry spells.

Effects of phorate on ducklings in northern prairie wetlands

Article Abstract:

A study has been conducted to investigate the direct effects of the insecticide phorate on waterfowl by exposing mallard ducks, Anas platyrhynchos, in South Dakota wetlands. Results showed that phorate causes toxicity in ducks at all concentrations. Ducklings that were younger and in control mesocosms had a greater survival rate than ducklings that were older and in treated mesocosms. Physiological analyses showed that phorate reduces cholinesterase activity in the brain and blood. These results showed that phorate may be used to control duckling survival in wetlands.

Survival and habitat use by ring-necked pheasants during two disparate winters in South Dakota

Article Abstract:

Severe winter weather is a major factor in the survival rates of ring-necked pheasants in South Dakota. A new study uses radiotelemetry to monitor survival rates of pheasants in eastern South Dakota during two contrasting winters. It is shown that mortality caused by predation was higher than mortality due to weather in both seasons. However, the provision of shelterbelts and food plot habitats is essential to pheasants during extreme winter conditions.
