Aspects of Mammalian Predation on Upland Nesting Waterfowl in Central North Dakota
… 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 one without predator control.</p> <p>Artificial waterfowl nests located in high density plots had a …

Translocation site selection for the nationally endangered grasshopper species Brachaspis robustus : A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Science at Lincoln University
… 31.1% >20 cm. Presence of native and introduced predators and level of predator control at currently occupied sites compared to potential translocation sites was investigated. Native and introduced predators were found to be present at all sites, but mammalian predator control is currently being …

The conservation sacrifice : how far New Zealand will go to save its birds
… the New Zealand government announced plans for Predator Free 2050, the biggest predator control effort ever undertaken in the country-and perhaps the world. Predator Free 2050 is a government-sanctioned goal to eliminate rats, stoats, and possums from New Zealand. Since New Zealand has no native …

Seguimiento y gestión de sistemas depredadores-presa : aplicación a la conservación de fauna amenazada
… capítulo aborda la gestión de la depredación sin control de depredadores: mediante la mejora del refugio disponible para la presa. Se desarrolla en un ámbito mediterráneo con poblaciones de conejo de baja densidad donde, además de depredadores generalistas, hay otros especialistas amenazados cuya …

Mothers transfer information via eggs: effect of mothers' experience with predators on offspring
… offspring of mothers that had been exposed to a predator during oogenesis (experimental) were compared to offspring of mothers that had not been exposed to a predator (control). I measured the consequences of maternal exposure to predation risk on the number and size of eggs, egg cortisol …

An investigation into the root of two of the main vulture threats: poisoning and belief-based use of vulture body parts in Southern Kenya
… Further, 22% fence off their livestock against predatory wildlife. We further explored how predation protection measures used predict individual poisoning likelihoods. None of the five main predation protection measures significantly influences poison use. Both fencing and the use of lights as …

Influence of light conditions on the dynamics of Tetranychus urticae and its control by the predatory mite Neoseiulus californicus
… spider mite (Tetranychus urticae) and its control by the predatory mite Neoseiulus californicus. Three light treatments were applied: natural light, 12h LED light and 12h dark, and continuous 24h LED light. Spider mite and predator densities were monitored twice a week. Spider mite …

Using Conditioned Food Aversion (CFA) to reduce Pied Crow (Corbus albus) predation of plover nests
… Many lethal and non-lethal methods of predator control can be ineffective, unethical, time-consuming and expensive to implement. An alternative is the use of Conditioned Food Aversion (CFA), a method by which animals are deliberately induced to avoid nests following consumption of eggs …

Guarding dogs as a mitigation tool in human-wildlife conflict - case study: the Anatolian Shepherd Dog breeding project in Namaqua National Park
… of conservation, fewer respondents used lethal predator control methods in the years after placement of the dogs than before their placement. The overall perception regarding the use of lethal control methods (e.g. gin traps, shooting and poison) was that such control is cruel and that it is …

Factors affecting foraging by breeding farmland birds
… Song thrush nest survival was affected by predator control, nest site location on the farm and habitat. Skylarks selected sparse vegetation and bare ground when foraging in winter cereals. Each species selected some invertebrate taxa over others, independently of chick age. Skylarks and …

Ecology, population dynamics and management of the bobwhite quail, Colinus virginianus marilandicus (L.), in Massachusetts
… were of limited value to quail. Likewise, predator control and refuge establishment were thought to be ineffective techniques. The use of narrow-strip annual grain plantings with maximum edge in areas reverting to non-productive habitat apparently provides the most economical ($2.50 per …

The landscape ecology of brown hares and European rabbits in pastures in the north east of England
… with contrasting effects for the two species. Predator control appeared more important in increasing rabbit numbers than hares in the studied region. Our results indicate that recent changes in pasture management in the UK might favour high rabbit densities with potentially significant economic …

Ecology and conservation of the Såli (Micronesian Starling, Aplonis opaca) in the presence of the invasive Brown Treesnake (Boiga irregularis) in Guam, Mariana Islands
… their fledglings are highly vulnerable to predators. My research focused on refining our understanding of how BTS are impacting Såli ecology and survival, and how BTS management can benefit Såli conservation. In my first chapter, I conducted the first field study to investigate the …

Restoration of threatened species populations: tuatara rehabilitations and re-introductions
