Successful conditioned taste aversion in jaguars
2023, Applied Animal Behaviour ScienceThe effectiveness of conditioned aversion in wolves: Insights from experimental tests
2020, Behavioural ProcessesCitation Excerpt :In a previous study, we increased the survival of translocated rabbits sprayed with vanilla essence after inducing odour aversion with microencapsulated levamisole plus vanilla essence in rabbit meat baits in the release areas (Tobajas et al., 2020c). In the livestock predation context, several studies in both the laboratory and the field have shown that a proportion of coyotes can acquire aversion to baits of a specific prey, and subsequently learn to avoid live prey (Gustavson and Nicolaus, 1987; Gustavson et al., 1976; Ellins et al., 1977); however, these studies have several drawbacks (Table 1). In fact, subsequent experiments failed to replicate these findings (Bourne and Dorrance, 1982; Burns, 1983).
Using conditioned taste aversion to reduce human-nonhuman primate conflict: A comparison of four potentially illness-inducing drugs
2020, Applied Animal Behaviour ScienceCitation Excerpt :Those with a moderate aversion take more than 15 min to eat a preferred food, while those with a strong aversion refuse to eat a preferred food and may even show some uneasiness while near the food. CTA has been used effectively in wildlife conservation and management to reduce coyote and wolf predation on sheep (Ellins et al., 1977; Gustavson et al., 1976), raven and raccoon predation on eggs (Avery et al., 1995; Nicolaus and Nellis, 1987), and bear consumption of pre-prepared meals (MREs) that they sought out and consumed previously (Polson, 1983; Ternent and Garshelis, 1999). In these studies, a food item that the animals actively targeted was treated with an aversive compound, and after the animals consumed the treated food and became ill, they avoided the food item.
Conditioned taste aversion in the grey fox (Pseudalopex griseus), in Southern Argentine Patagonia
2015, Applied Animal Behaviour ScienceCitation Excerpt :Second, it could be used to generate CTA to livestock using beef hides retaining the typical taste and scent of domestic livestock prey on the outer surfaces wrapped securely around ground meat. This was indicated by Ellins et al. (1977) in coyotes, inhibiting predation between two sheep herds using sheep carcasses laced with lithium chloride, adjacent to the herds. Since Levamisole may be safer and easier to work with than lithium chloride and our results indicate that it produced reliable aversion among grey foxes, it might be a worthy addition as a management tool for wild populations.
Learned food aversion with and without an odour cue for protecting untreated baits from wild mammal foraging
2007, Applied Animal Behaviour SciencePerceived effectiveness of livestock-guarding dogs placed on Namibian farms
2005, Rangeland Ecology and ManagementCitation Excerpt :Livestock losses can have a severe economic impact on farmers, especially in poorer farming regions of the world (Oli et al. 1994; Hussain 2003), and many losses are attributed to predators (Andelt 1992; Andelt 1999). A wide variety of techniques aimed at reducing livestock depredation have been developed, such as the use of electric fencing, lethal predator control, toxic collars, disruptive stimuli, and various aversive techniques (Shivik et al. 2003; Treves and Karanth 2003), and such strategies have been employed on farmland with varying degrees of success (Ellins et al. 1977; Forthman Quick et al. 1985; Veeramani et al. 1996). However, such methods are often relatively costly in terms of equipment, technology, and/or labor, and these costs can be prohibitive in many situations, especially in developing countries (Treves and Karanth 2003).
