Quantifying The Edge Effects Associated With Predator Removal Blocks On The Nesting Success Of Upland Ducks In North Dakota, Margaret Jean Kuhn
Quantifying The Edge Effects Associated With Predator Removal Blocks On The Nesting Success Of Upland Ducks In North Dakota, Margaret Jean Kuhn
LSU Master's Theses
Much evidence suggests that nest success is one of the key drivers of duck production. Accordingly, for the past thirty years, waterfowl managers have focused their efforts on increasing nest success. One way to increase nest success is through predator trapping. Previous studies have shown that predator trapping increases nest success on different sized trapped blocks. This study attempted to answer the question: does trapping affect nest success on areas directly adjacent to trapped block boundaries? I hypothesized that predator abundance outside trapped blocks would be reduced. I predicted that nest success would decline with distance from the boundary while …

Effects Of Predator Activity On The Nesting Of American Black Ducks And Other Birds On Barrier Islands In The Mid-Atlantic Coast, Brian Joseph Arquilla

Landscape change throughout North America has resulted in heightened nest predator population and declining avian productivity. Essential to establishing effective management design is an understanding of differential predation pressure among avian groups as group specific responses to predation impact may exist. The objective of this study was to examine the efficacy of predator trapping on the nest success and density of ground nesting avifauna in 2004-2005 in the Virginia Coast Reserve, specifically dabbling ducks, Canada Goose and Willet. Second, we determine the impact of predation on ground nesting birds by relating indices of predator abundance to nest density and nest …
