It is usually considered a classic conditioning learning. J. The sauce-bearnaise syndrome. Systematic reviews and maps as tools for applying behavioral ecology to management and policy. Although this technique was used historically in over 20% of (almost exclusively captive) applications, it has rarely been used in the last 10 years (Figure 5). J. Wildl.

Supplementary Figure 1. Rooke, I. J. Conserv. A. Sci. Optimal dosages can be determined by either performing captive trials with the species of interest, or similar species, or by using existing literature on the substance (e.g., Table 2). Another option is to artificially increase novelty by adding a new stimulus to a familiar, conditioned stimulus, such as a visual or odor stimulus (Baker et al., 2007, 2008; Tobajas et al., 2021a). 10, 385388. (1961). The majority of studies we found addressed HWC in carnivores (e.g., coyote, Canis latrans), followed by songbirds (e.g., red-winged blackbird, Agelaius phoeniceus) (Table 1). Tactile stimuli are more likely to be effective with species that handle their food before ingestion, such as rats, monkeys and raccoons. We learned in class how farmers would put a poison on their sheep's wool that would make wolves nauseous. Conditioned taste aversions: from poisons to pain to drugs of abuse.

In some wildlife conflict situations, social transfer of CTA was explicitly not observed. 17, 329346. doi: 10.1201/9781420032581.ch1, Conover, M. R., Francik, J. G., and Miller, D. E. (1977). Modern wildlife management has dual mandates to reduce human-wildlife conflict (HWC) for burgeoning populations of people while supporting conservation of biodiversity and the ecosystem functions it affords. learned to avoid baits after ingesting a sub-lethal dose of the poison they contained for lethal population control (Elton, 1954), identifying the mechanism of a phenomenon that had already been described as bait-shyness (Rzska, 1953).

The substances used in the last 10 years (since 2011) that showed promising results are listed in Table 2, along with the associated species, conflict context, food types, field or captive setting, and references. A stimulus can be referred to as salient when it is noticeable (e.g., prominent, conspicuous) in comparison to its surroundings. Methiocarb-induced aversion to grapes by gray-backed white-eyes. 12:20150863. doi: 10.1098/rsbl.2015.0863, Ward-Fear, G., Thomas, J., Webb, J. K., Pearson, D. J., and Shine, R. (2017). doi: 10.1007/s40011-015-0633-7, Clark, L. (1998). Then we described how to generalize aversive responses among contexts, avoid detection of emetic substances and use surrogates and supportive stimuli. For example, research on Norway rats decades ago demonstrated their inability to associate audio-visual stimuli with nausea, while they were able to rapidly associate taste stimuli with nausea (Garcia and Koelling, 1966). The strong selection pressure to avoid fatal poisoning is the reason CTA can occur even when an animal is unconscious (Roll and Smith, 1972) and supports learning with only one or very few trials (Garcia et al., 1974). Many CTA interventions do this by regularly replenishing baits or eggs (e.g., Dimmick and Nicolaus, 1990; Indigo et al., 2018; Tobajas et al., 2020a, 2021a). Appl. Anim. 43, 209211. Even though other conditioning methods require the time interval to be on the scale of seconds or minutes (Domjan, 2018), the time interval between the conditioned and unconditioned stimulus in CTA applications can be as long as tens of minutes to several hours (Garcia et al., 1966; Cowan et al., 2000; Domjan, 2018). Relative number of experiments per taxonomic order categorized by human-wildlife conflict category. Bait shyness, a study in rat behaviour. Hum. Social transmission of avoidance among predators facilitates the spread of novel prey. However, dogs (Canis lupus familiarus) were still able to detect the levamisole and the encapsulation might have even weakened the CTA by delaying the release of levamisole (Tobajas et al., 2019b). Indeed, in <15% of field studies (four experiments) that clearly involved pre-existing conflict, could the authors be sure that subjects were repeatedly exposed to the emetic and in only 16% of studies did authors explicitly state subjects were not repeatedly exposed (Supplementary Data 1). For each question, we offer specific implementation suggestions and methods for achieving them, which we summarize in a decision-support table that might be used by managers to guide their use of CTA across a range of contexts. Rev. J. Appl. Behav. In order to condition animals in situ with safer and practical food stimulus researchers created toad sausages (Price-Rees et al., 2011). These aversions are a great example of how classical conditioning can result in changes in behavior, even after only one incidence of feeling ill. What Is Conditioned Taste Aversion? Pen trial of estrogen-induced conditioned food aversion to eggs in raccoons (Procyon lotor). 33, 112121. This particular form of classical conditioning is most commonly known as conditioned taste aversion (Garcia et al., 1974).

Conditioned taste aversion is often used in laboratories to study gustation and learning in rats. (1991). Acta Agric. Latent Inhibition and Conditioned Attention Theory. Although safer and more likely to be effective (the substance can by definition not be detected in the food), this is practically and logistically very challenging to manage in the field. PLoS ONE 14:e0217458. doi: 10.1071/WR18037, Foley, N. C., Jangraw, D. C., Peck, C., and Gottlieb, J. Bull. Early studies on CTA interventions in predator conflicts used live prey (Horn, 1983), but such approaches are no longer ethically tenable and are often outlawed by legislation (Marshall et al., 2019). Soc. Fear Conditioning; 5.2. Only in 53% of 19 field experiments that clearly involved pre-existing seasonal conflict, CTA appeared to be (partially) conducted outside the conflict season. doi: 10.1111/j.1439-0310.2011.01935.x, Price-Rees, S.

R., and Martin, G. C. (1981). Anim. Although CTA is exceptional, in that it may be effective after only one trial (Garcia et al., 1974), additional trials, to increase the absolute and relative exposure to the illness in combination with the food, are likely to increase the strength of the CTA (Fenwick et al., 1975; Navarro et al., 2000; Tobajas et al., 2020c). Anim. 25, 117. One promising strategy to promote generalization from the conditioned stimulus used in training to the living food resource would be to add additional olfactory or visual stimuli or both, depending on the primary senses used by the species during foraging (Elmahdi et al., 1985; Baker et al., 2008; Tobajas et al., 2019b). Eyeblink Conditioning; 5.3. Applications of conditioning for the management of human-wildlife conflict are typically aversive, and involve one or more unconditioned stimuli that animals predictably avoid, such as pain, fear, or illness. Examples of emetics used in the last 10 years that were reported to, in some degree, successfully (as defined by the authors of the respective studies) induce CTA to a conditioned stimulus (CS) in a current or prospective future wildlife conservation or management context.

This overview reveals substantial biases in the HWC contexts, geographic locations, and study species that limit the generality of the principles we describe below. 43, 139149. 163, 167174. This is a form of classical condition when the body uses a natural instinct as a means of protection. 92, 159168. We synthesized these meta-data in a spreadsheet that can be sorted and manipulated by others (Supplementary Data 1). Establishing CTA is more challenging when animals have previously and repeatedly consumed a certain food without getting sick (Lubow, 1989; Delacasa and Lubow, 1995). 79, 398407. However, there appears to be a trade-off when it comes to diet diversity, since aversions are also only likely to be persistent when sufficient alternative foods are available to the animal (Dethier and Yost, 1979; Ratcliffe et al., 2003), reducing the energetic and potential fitness cost of avoiding the treated food type (but see Potter and Held, 1999). Higher doses also increase the detectability of the emetic substance in species with a keen sense of smell (e.g., Cagnacci et al., 2005). Res. Rats tested with a sucrose solution paired with a drug that gave positive, euphoric effects, such as amphetamine, cocaine, and morphine emitted positive reactions to the drugs, yet they avoided approaching these solutions. (2017) specifically studied whether CTA transferred over generations after conditioning captive quolls to avert toxic cane toads and reintroducing them into the wild. Mason and Reidinger (1983) tested this in captivity by attaching a colored rectangular card to the feeding bowl of red-winged blackbirds during the conditioning phase. Despite extensive support for the power of CTA in laboratory studies, field studies have exhibited mixed results, which erodes manager confidence in using this tool. doi: 10.1016/S0091-6773(76)90272-8. Vienna: R Foundation for Statistical Computing. Figure 4. However, dead animals or animal parts present as very different stimuli compared to live animals. (1911). doi: 10.3758/BF03326736, Gentle, M., Massei, G., and Quy, R. (2006). It is challenging to predict which conditioned stimulus (i.e., food characteristic) an animal will use. If our caveman ancestors ate tainted or poisoned food, it could kill them; however, through the process of conditioning, our ancestors learned quickly to avoid potentially deadly foods. This final criterion required that authors measured the response of treated individuals exposed to the conflict resource when the illness-inducing substance was not present. doi: 10.2307/3899029, Langley, W. M., and Knapp, K. (1982). This demonstrated that the particular stimulus used in conditioning can matter: some stimulus pairings generate stronger aversion than others. Psychobiol. 9, 247257. Despite these misgivings, researchers have continued to explore the use of CTA in a variety of contexts with a few studies published in most years (Figure 1), mostly on mammals and birds, but also on reptiles. CTA is more efficient as a management tool when individuals retain learned aversions for a long time and if it can transfer to the level of populations. Taste avoidance and taste aversion: evidence for two different processes. The single study conducted seemingly independently occurred in Japan (Matsuzawa et al., 1983). (1982). (1983). J. Wildl. Predator-resembling aversive conditioning for managing habituated wildlife. Ecol. J. Wildl. For example, application of CTA with crop species has been trialed frequently (Table 1; Figure 1), but may not generalize to plant species that are to be protected for their cultural value or because they are at risk of extinction. Sci. 66, 679687. Evol. In cattle, CTAs retained for as long as a year were lost after social contact with untrained conspecifics (Lane et al., 1990). An illustrative example of application of this technique in wildlife management was its use to teach black bears (Ursus americanus) not to eat pre-packaged military rations (Ternent and Garshelis, 1999). Manag. The effect of different levels of pre-exposure to sucrose on the acquisition and extinction of a conditioned aversion. J. Comp. Different colors refer to how the substance was administered, either directly applied to the subject (e.g., injected; blue) or applied to the food resource (black). Anim. Cambridge: Cambridge University Press. Range Manag. Up to now, only very few field experiments (four), comprising three Carnivora families, used TPOA and all reported some degree of success (Supplementary Data 1). One potential way to overcome this problem of detectability is to present treated and control foods at the same time and place, which could make it harder for animals to link substance characteristics to the illness, a procedure that showed promise in American black bears (Homstol, 2011).

They were able to keep their sheep safe because animals create a huge aversion to things that make them ill for survival. Sci. 89, 11531164. A recent study with captive wolves showed more promising results with new kind of micro-granulated levamisole (Tobajas et al., 2020b), but here, too, the increased volume needs to be masked by a relatively big food item. .

Appetite 6, 276281. Ecol. Behav. Cogn. Manage. Manag. From an evolutionary perspective, it is expected that effective substances can cause CTA at low dosages (Lin et al., 2017), because larger doses would be lethal. Proc. Nevertheless, <5% of field experiments explicitly reports using either a resinate, micro-encapsulation or thiram (one experiment for each; Supplementary Data 1). Throughout our review, we identified some areas that first require further research before concrete recommendations can be offered. Behav. Another option is to mask the taste, smell or color of the illness-inducing substance. Populations of short-lived, compared to long-lived, species will need more frequent retraining, since a proportion of nave individuals will quickly recruit into such populations with each new generation. Certain other cephalosporin antibiotic medications, like cefotetan and cefazolin are metabolized to a compound that has similar effects at blocking acetaldehyde metabolism, 1-methylthiotetrazole (1-MTT), and can cause the same hangovers upon alcohol ingestion. The efficacy of CTA can be reduced when an individual ingests too much bait and becomes incapacitated or, if it vomits too quickly, preventing it from ingesting or digesting enough substance to generate an association with nausea (Conover et al., 1977). Two good examples of biological influences on conditioning are taste aversion and instinctive drift. A 3-year evaluation of taste aversion coyote control in Saskatchewan. Soc. Sci. Food aversion is feeling disgusted or repulsed by certain food and you won't eat it. While it might be undesirable to color all crop plants, it could be feasible to surround an entire field with distinctly colored flags that birds have trained to associate with the experience of illness.

Mason and Reidinger (1983) also showed that the aversion could be transferred from one food type to another, given that the other food contained the same color stimulus. Conditioned stimuli that are paired with illness are most likely to be noticeable when they relate to the sensory modality that the species primarily uses to find food. Coyote predation control by aversive conditioning. Pre-exposure to the food can sometimes be reduced to promote a stronger association with illness by, for example, targeting young animals, conditioning individuals before reintroduction of animals to a novel environment, planning conditioning just before the presence of seasonal foods, or by adding novel stimuli to the conditioned foods. doi: 10.1016/j.applanim.2005.08.005, Gentle, M., Massei, G., and Saunders, G. (2004). 53, 12411250. Moreover, an animal may be sensitive to different kinds of stimuli depending on whether it is searching, attacking or consuming a prey (Langley and Knapp, 1982). Demonstration of a socially transmitted taste aversion in the rat. Behav. Rev. doi: 10.1037/0000057-000, Domjan, M., and Hanlon, M. J. Yet, substantial variation is apparent even among English-speaking countries. Because successful CTA in HWC requires that aversion to treated food is also generalized to untreated conflict resources, we devote the next section to the circumstances that stimulate or hamper such generalization (Stage 3: How can generalization of CTA to untreated resources be encouraged?). doi: 10.1111/conl.12458, Brett, L. P., Hankins, W. G., and Garcia, J. In these studies, animals that consume a bait laced with an undetectable dose of an aversion agent avoid both baits and live prey with the same taste and scent as the baits. A compelling experiment compared pairing of nausea with taste, versus pairing with light and sound stimuli ("bright noisy water"). Specifically, the use of a hormone such as ethinyl estradiol, a synthetic estrogen, can have detrimental effects for certain individuals in the population. Supplementary Data 1. (1966).

For example, in a study of raccoons (Procyon lotor), ethinyl estradiol was safely ingested by most raccoons, but it apparently caused the death of a pregnant female (Dueser et al., 2018) and the compound is known to have detrimental effects on unborn fetuses (Yasuda et al., 1981). Under these circumstances, conditioned taste aversion is sometimes known as the "Sauce-Bearnaise Syndrome", a term coined by Seligman and Hager.[2]. Behav. Strong aversions developed to the taste stimuli but not to the light and sound. Next to the substance type, dosage typically determines stimulus intensity. Assuming CTA is suitable to the situation, we follow by describing how learning theory can guide the application of CTA (Stage 2: How should CTA be applied? In contrast, in operant conditioning, an animal's behavior does influence the presence of the unconditioned stimulus, i.e., animals have some voluntary control over their subsequent experience. Which of the following characteristics of taste aversion conditioning make it different from other forms of classical conditioning? Behav. An important consideration in field applications is environmental stability of the substance. 4, eds J. D. Paterson and J. Wallis (Norman, OK: American Society of Primatologists), 420443.

Similarly, American crows (Corvus americanus) learned to avoid green-painted eggs after being subjected to some containing a non-lethal toxin called landrin (Nicolaus et al., 1983). We collected published studies on CTA application in HWC by conducting a systematic search, using Web of Science and Scopus (September 2020), and supplemented this with literature retrieved ad hoc through Google Scholar, reference lists in other papers, and expert suggestions.

Bull. We share some very preliminary estimates of success based on the conclusions made by the respective authors as a guidance for readers, but stress that these assessments by authors are not comparable to a quantitative systematic review.

Learned food aversion with and without an odour cue for protecting untreated baits from wild mammal foraging. In the treatment where a combination of taste and odor (bait and clove oil) was used, the aversion was successfully generalized to untreated bait sprayed with clove oil, while in the ziram only treatment no generalization occurred. For example, if you like the texture . They found that the offspring of trained female quolls exhibited higher rates of survival, but they could not determine whether this occurred because the young quolls had learned from their mothers not to consume toads or whether they benefited from a rapid genetic adaptation of avoidance acquired from their untrained fathers (Kelly and Phillips, 2019). Wildl. Similarly, when artificial foods are used for training instead of natural foods and these natural foods are prone to spoiling (e.g., eggs), the difference might help predators discriminate between treated (artificial) food items and untreated (natural) food items (Brinkman et al., 2018). As a consequence, animals with benign pre-exposure to foods, are likely to require more trials to effectively establish CTA (e.g., Maguire et al., 2009). Appl. Further, research should explore use of selective bait deployment methods to reduce ingestion by non-target animals and the smart use of lures or attractants to increase the food detectability specifically by the target species (Ferreras et al., 2018; Tobajas et al., 2021b). Manage. Taste aversion is a common problem with chemotherapy patients, who become nauseated because of the drug therapy and then develop aversions to food. Manage. Unfortunately, using the resinate creates the need to use a bigger volume of substance for the same effective dose. 52, 259264.

In addition, presenting the treated items in a way that discourages systematic consumption by non-target species (Tobajas et al., 2020a), such as in rings of powdered insecticide (Indigo et al., 2018), will also improve exposure probability. Anim. In the following paragraphs, we go into more detail about the factors that may hamper or promote stimulus generalization. However, sample sizes were frequently small (i.e., up to 10 individuals) or, particularly in field studies, were not precisely known (Table 1; Figure 4), with the exception of studies in the context of crop/plant consumption and toxic species/bait consumption (Table 1). This is typically easier to achieve when humans partially control the presentation of food items, such as in agriculture, certain protected breeding populations, or baiting projects. The Garcia effect explains that the aversion develops more strongly for stimuli that cause nausea than other stimuli. This is considered an adaptive trait or survival mechanism that enables the organism to avoid . More recent studies of CTA for wildlife management emphasize the contexts of successes (e.g., Baker et al., 2008; O'Donnell et al., 2010; Tobajas et al., 2020a; Ferguson et al., 2021) and the limitations that produce failures (e.g., Catry and Granadeiro, 2006; Neves et al., 2006). We apply learning theory to the chronological stages of CTA application in the field and illustrate them by synthesizing and reviewing past applications of CTA in HWC situations. 54, 428432. Psychon. 12, 414420. Brain Res. 45, 505517. Studies were retrieved via systematic search and ad hoc retrievals (see Methodology). Flavor-illness aversions: the peculiar roles of odor and taste in memory for poison. The growing prevalence of human-wildlife conflicts is of increasing conservation concern and has invited comprehensive study of intervention methods (Conover, 2002; Eklund et al., 2017; van Eeden et al., 2018) with increasing emphasis on less invasive and non-lethal techniques (e.g., Smith et al., 2000; Shivik et al., 2003; McManus et al., 2015). The eleven orders belonged to three classes (birds, mammals and reptiles). Lack of novelty in the field was a consequence of pre-existing conflict, a before-after study design or both. Inflicting sickness is what gives CTA its evolutionary relevance and power to deter consumption in the future. However, not all animals can learn food aversions from conspecifics and rats appear to be especially variable in their responses to conspecifics (Kuan and Colwill, 1997; Galef and Whiskin, 2000). A conditioned taste aversion involves the avoidance of a certain food following a period of illness after consuming that food. Number of subjects in captive and field experiments. Annau, Z., and Kamin, L. J. J. Anim. The category Valued species depredation comprises depredation of species that do not fit in the other depredation categories (e.g., game, pets and protected species), Anthropogenic resource consumption comprises resources that do not fit the other HWC categories (e.g., beehives, landfills, food hand-outs). This may explain why, thus far, supporting stimuli have been added only in <25% of field experiments and mostly with the aim of facilitating generalization (see Stage 3) rather than increasing novelty (Supplementary Data 1).

Specifically, we discuss (1) when CTA is suitable, (2) how aversion can be most effectively (and safely) established, (3) how generalization of aversion from treated to untreated food can be stimulated and (4) how extinction of aversion can be avoided.
