Response of predators to Western Sandpiper nest exclosures Response of predators to Western Sandpiper nest exclosures
In 2001, predator exclosures were used to protect nests of the Western Sandpiper (Calidris mauri) in western Alaska. During the exclosure experiment, nest contents in exclosures had significantly higher daily survival rates than control nests, however, late in the study predators began to cue in on exclosures and predate the nest contents. An Arctic Fox (Alopex lagopus) dug under one...

Spatial variation in shorebird nest success: Implications for inference Spatial variation in shorebird nest success: Implications for inference
Estimates of nest success are widely applied in order to evaluate a multitude of theoretical and practical issues. Frequently, however, researchers fail to limit their inferences to the appropriate spatial scale. We evaluated small-scale variation in nest success of Western Sandpipers Calidris mauri during a four-year study on the Yukon-Kuskokwim Delta in western Alaska. We use these...

Densities of breeding birds and changes in vegetation in an alaskan boreal forest following a massive disturbance by spruce beetles Densities of breeding birds and changes in vegetation in an alaskan boreal forest following a massive disturbance by spruce beetles
We examined bird and plant communities among forest stands with different levels of spruce mortality following a large outbreak of spruce beetles (Dendroctonus rufipennis (Kirby)) in the Copper River Basin, Alaska. Spruce beetles avoided stands with black spruce (Picea mariana) and selectively killed larger diameter white spruce (Picea glauca), thereby altering forest structure and...
