Improving ungulate habitat in a region undergoing rapid energy development: consequences for songbirds and small mammals
Habitat manipulation intended to mitigate the impact of energy development on game animals is well underway in the western U.S. Yet, the consequences of these actions for other species are not well understood. A habitat manipulation experiment was established in the Piceance Basin, a region of …

Methods for assessment and techniques for management of striped legless lizard Delma impar populations in South-Eastern Australia
… was found to be a useful tool for conducting habitat manipulation experiments on the species. However, the use of artificial shelters, roof tiles in this case, is cheaper, less labour intensive and less disturbing and therefore provides an adequate survey tool. Surveys conducted in spring …

Influence of Vegetation On The Distribution of Small Mammals On A Waterfowl Production Area
… as much as the regulation of density of cover. Habitat manipulation could be an important management tool when more information is gained on the role small mammal’s play in determining predation and population of carnivores.

Effects of water willow establishment on littoral assemblages in Kansas reservoirs: focus on age-0 largemouth bass
A large scale habitat manipulation was conducted to assess the effects of establishing an emergent macrophyte, American water willow Justicia americana, on littoral reservoir communities. Coves in three large (>1,800 ha) Kansas impoundments were chosen and half planted with water willow. Sampling …

Seasonal habitat use and survival of brown trout (Salmo trutta) in Oatka Creek, Monroe County, New York
… New York. Management agencies are considering habitat manipulation to reduce the severity of overwinter merganser predation on the wild brown trout population in Oatka Creek Park (OCP; Monroe County) but currently lack data to make an informed decision. My study sought to 1) quantify the …

Enhancing the biological control of leafrollers (Lepidoptera: Tortricidae) using floral resource subsidies in an organic vineyard in Marlborough, New Zealand
In this thesis, experiments were conducted in both the laboratory and the field to determine whether the provision of floral resources to Dolichogenidea tasmanica Cameron (Hymenoptera: Braconidae) could enhance the biological control of leafrollers (Lepidoptera: Tortricidae) in an organic vineyard …
