Factors Influencing Depredation of Artificial Duck Nests

The Journal of Wildlife Management, 1993
Because artificial nests can facilitate controlled experiments of nest success, we used them to assess whether human visitation, nest density, vegetation structure, and proximity to habitat edge could affect depredation of duck nests on Yukon Flats National Wildlife Refuge, Alaska.

Artificial Nest Experiments: Effects of Nest Appearance and Type of Predator

The Condor, 1987
Nest predation is a primary cause of nesting mortality for many bird species (Skutch 1949, 1966; Nice 1957; Ricklefs 1969; Nilsson 1984). Food limitation and competition also can affect nesting success (see reviews in Martin 1986, 1987). However, the primary role of nest predation in nesting mortality suggests that it can be a strong agent of selection

Nitrate dynamics in artificially drained nested watersheds

Physics and Chemistry of the Earth, Parts A/B/C, 2011
Abstract There is concern that subsurface drainage, by destroying or by-passing active denitrification areas, may prevent nitrate retention processes and enhance nitrate contamination of surface water by agriculture. To address this question, we studied the flow and concentration signatures of drainage waters and their transformations in a series of ...

Cavity nesting in stitchbirds and the use of artificial nest sites

Notornis, 1989
Cavity nesting by Stitchbirds (Notiomystis cincta) was studied on Little Barrier Island by adding artificial nest sites (boxes) in a breeding habitat. The addition of boxes was a test of the theory that the number of breeding pairs of cavity nesting species is limited by the availability of suitable holes for nest sites. Site limitation is also said to
