Cascading Effects Of Predator Removal On The Ecology Of Sea Turtle Nesting Beaches
… Many previous studies have demonstrated that the removal of top predators from terrestrial ecosystems can have broad-scale impacts on community ecology. I examined the direct and indirect effects of raccoon removal from sea turtle nesting beaches in east-central Florida during the summers of 2003 …

Investigating the Effects of Urban Features on Bird Window Collisions
… area. After accounting for surveyor bias and predator removal, the rate of collision was 7.7 4 SD birds/building/year. A negative binomial GLM determined collision frequency to be significantly predicted by proportional vegetation area, distance to vegetation, window area and wall vegetation. …

A paleozoological perspective on predator extermination and white-tailed deer (Odocoileus virginianus Boddaert) overabundance in central Texas.
… virginianus texana) populations in some areas. Predator extermination has dramatically reduced the average body size of members of the extant predator guild, and large carnivores most capable of hunting white-tailed deer are extirpated. Character release in the remaining “large” …

Generalist predators in reduced-tillage corn: predation on armyworm, habitat preferences, and a method to estimate absolute densities
The potential impact of generalist predators on armyworm mortality was evaluated in the field, through a predator removal study, and in the laboratory, through controlled feeding trials. The most common potential armyworm predators removed from the field included ground beetles (Carabidae), rove …

Survival, Movement, and Fine-Scale Habitat Selection of Reintroduced Texas Horned Lizards (Phrynosoma cornutum)
… However, methods to increase survival, such as predator removal and initial release of more lizards, should be used to ensure greater success.

Assessing the Effects of Sea-Level Rise on Piping Plover (Charadrius Melodus) Nesting Habitat, and the Ecology of a Key Mammalian Shorebird Predator, on Assateague Island
… of the red fox (Vulpes vulpes), a key shorebird predator at Assateague Island, Maryland and Virginia. We constructed and tested a model that links changes in geomorphological characteristics to piping plover nesting habitat suitability. We then linked this model to larger scale shoreline change …

Piping plover population dynamics and effects of beach management practices on piping plovers at West Hampton Dunes and Westhampton Beach, New York
… nesting. We also obtained indices to human and predator presence on the beach. The WHD piping plover population increased from 0 pairs in 1992 to 39 in 2000 then decreased to 18 pairs in 2004. This decline was closely associated with changes in potential nesting habitat which increased from 22.4 …

Aspects of the ecology and management of small mammalian predators in northern New Zealand
… at Trounson Kauri Park, Northland New Zealand. Predatory mammals were monitored by radio telemetry through a 1080 then brodifacoum poison baiting operation at Trounson Kauri Park in Northland, New Zealand to target possums (Trichosurus vulpecula) and rodents (Rattus rattus, Rattus norvegicus & …
