  2. Relations between forest and prairie fragmentation and depredation of artificial nests in Missouri

    Burger, Leslie DonaldsonUniversity of Missouri--Columbia1988

    "Human settlement of native ecosystems has resulted in the destruction and fragmentation of habitats until, in many cases, only isolated remnants remain. The emerging field of conservation biology often examines these fragments, attempting to illucidate patterns of diversity, the mechanisms that …

  3. A study of avian nest predation at Audubon Acres in Chattanooga, TN

    Langley, Melea R.2007

    … affecting life histories and habitat selection. Artificial nests are commonly used to study nest predation because they allow the researcher to investigate comparative treatments and their impact on predation. Relative nest predation was studied at Audubon Acres in Chattanooga, TN using …

  4. Aspects of Mammalian Predation on Upland Nesting Waterfowl in Central North Dakota

    Trevor, John Thompson

    … during the summers of 1987 and 1988. Survival of artificial nests was examined in relation to nest density, vegetation cover, distance from roads, active predator dens, and other artificial nests in a plot. Survival of artificial nests was also compared between an area with predator control and …

  5. Impacts of Vegetation Density and Distance from the High Tide Line on Raccoon Predation of Diamondback Terrapin Nests in Jamaica Bay, NY – A preliminary study

    Teitelbaum, Zvi2020

  6. An experimental analysis of nest predation in eastern deciduous forests

    Marini, Miguel AngeloUniversity of Illinois at Urbana-Champaign2011

    … studied how richness, density, and frequency of nests, and the fragmentation of forests through alterations of the landscape and forest structure affect nest predation levels. I estimated predation levels using over two thousand natural translocated nests and on artificial nests baited with quail …
