“…As the solution was not applied on the forage plant itself and also offered no visual signal, it is most likely that the smell was the responsive cue for the chamois to reduce foraging. These results link to several studies that reported strong aversion towards swards treated with manure or slurry (Pain et al 1974;Suárez and Orihuela 2002) and that odour was the cue used by the animals (Dohi et al 1991;Aoyama et al 1994). Odour may convey two slightly different types of information: Firstly, odour intensity can be seen as a measure of faecal density, and secondly, strong odour in faeces could indicate reduced health and thus higher parasite load (Bekele 2002).…”

“…Cooper et al (2000) found that sheep did not react to feeding patches experimentally infested with nematode larvae only, and although the sheep discriminated against patches contaminated with faeces, they did not discern between faeces from infected and uninfected animals. Thus, the presence of faeces rather than the parasites themselves seems to be the primary cue for risk assessment (Hutchings et al 2003), but odour may mediate the strength of the behavioural reaction (Dohi et al 1991;Aoyama et al 1994). Hutchings et al (1998) found that fresh faeces were more odoriferous and provoked stronger rejections of contaminated swards by sheep than older faeces.…”

“…Inter-specific dung avoidance has rarely been addressed (Benham and Broom 1991;Aoyama et al 1994;Daniels et al 2001) and hardly ever in a wider context of interspecific relationships (Gunn and Irvine 2003). Our results suggest that competitive imbalance between wild and domestic ungulates, particularly avoidance of feeding patches or habitats by the wild species, should not only be interpreted in terms of resource (or interference) competition but should also be considered under the aspect of different risk perception and susceptibility to infection with parasites and other pathogens excreted in faeces.…”

Wild ungulates often adjust spatial behaviour where they coexist with livestock. In European mountains, chamois Rupicapra rupicapra or R. pyrenaica commonly avoid alpine pastures used by domestic sheep. Mechanisms leading to competitive losing out of the wild species are not well understood, but mostly, resource competition is inferred and sometimes demonstrated. We hypothesised that chamois need to minimise the risk of intestinal parasite uptake and therefore would avoid pastures contaminated with sheep dung. We tested this in two experiments by contaminating feeding patches of wild and captive chamois with (parasitefree) sheep faeces. Wild chamois did not avoid grazing sites or plots on which sheep dung had been placed at a (low) density representing the commonly encountered situation in the Swiss Alps. Captive chamois strongly reduced browsing time on small trees given for food when the surroundings of the trees were sprayed with a watery faecal solution. We concluded that the odour signalled a potential high risk of parasite infection to the captive chamois, whereas the density of sheep dung on the grazing site of wild chamois was not high enough to be perceived as a risk. The need to minimise endoparasite uptake from faeces may therefore play a role in driving spatial behaviour of wild ungulates and could result in competitive imbalance between wild and domestic ungulates.

“…), even though animals may generally consume less food when it is placed near foul‐smelling scents. For example domestic sheep ( Ovis aries ) forage less when their food is placed near pig ( Sus scrofa ) or other sheep faeces (Arnould & Signoret, ), cattle ( Bos taurus ) avoid feeding near their own faeces (Dohi, Yamada & Entsu, ), and goats ( Capra hircus ) avoid feeding near cattle faeces (Aoyama et al., ). These responses are less related to fear, and more to repulsion, an adaptive response to minimize risk of disease (Hutchings et al., ; Ezenwa, ).…”

Biologically meaningful scents: a framework for understanding predator–prey research across disciplines

et al. 2017

Fear of predation is a universal motivator. Because predators hunt using stealth and surprise, there is a widespread ability among prey to assess risk from chemical information -scents -in their environment. Consequently, scents often act as particularly strong modulators of memory and emotions. Recent advances in ecological research and analytical technology are leading to novel ways to use this chemical information to create effective attractants, repellents and anti-anxiolytic compounds for wildlife managers, conservation biologists and health practitioners. However, there is extensive variation in the design, results, and interpretation of studies of olfactory-based risk discrimination. To understand the highly variable literature in this area, we adopt a multi-disciplinary approach and synthesize the latest findings from neurobiology, chemical ecology, and ethology to propose a contemporary framework that accounts for such disparate factors as the time-limited stability of chemicals, highly canalized mechanisms that influence prey responses, and the context within which these scents are detected (e.g. availability of alternative resources, perceived shelter, and ambient physical parameters). This framework helps to account for the wide range of reported responses by prey to predator scents, and explains, paradoxically, how the same individual predator scent can be interpreted as either safe or dangerous to a prey animal depending on how, when and where the cue was deposited. We provide a hypothetical example to illustrate the most common factors that influence how a predator scent (from dingoes, Canis dingo) may both attract and repel the same target organism (kangaroos, Macropus spp.). This framework identifies the catalysts that enable dynamic scents, odours or odorants to be used as attractants as well as deterrents. Because effective scent tools often relate to traumatic memories (fear and/or anxiety) that cause future avoidance, this information may also guide the development of appeasement, enrichment and anti-anxiolytic compounds, and help explain the observed variation in post-traumatic-related behaviours (including post-traumatic stress disorder, PTSD) among diverse terrestrial taxa, including humans.

“…Thus, that more cows preferred to lie down in Area 4 of the pen during a high incidence of flies strengthened the hypothesis that this behavior was displayed to reduce the effects of the blood-sucking, feeding habits of S. calcitrans. Aoyama et al (1994) and Suárez and Orihuela (2002) found that the volatile fraction of cattle feces has an aversive effect on cows and other herbivores, resulting in aversion behavior toward contaminated areas. Furthermore, it has been reported that stored manure, urine, and soiled straw bedding are preferred sites for oviposition of stable flies (Meyer & Petersen, 1983;Meyer & Shultz, 1990), suggesting that in these areas the fly population could be higher.…”

This study investigated the effect of controlling stable flies (Stomoxys calcitrans) on the number of dairy cows lying down and their pen distribution. The study randomly assigned 80 Holstein cows to 1 of 2 groups. The treated group (T) included cows individually sprayed with insecticide when found with an average of 10 stable flies per cow; in the control group (C), cows received no application of insecticide. The pen had 4 equal-size areas: (a) feeding, (b) drinking and sunny, (c) covered, and (d) manure. The study recorded the number of cows lying and the area of the pen where the nonhuman animal was located. The study found no difference (p > .05) between the proportion of T and C cows lying. However, cows preferred to lie down in pen area 3 when fewer than 10 stable flies per cow were found. Area 4 was the most avoided section of the pen, except when a high incidence of flies was present. The study concluded that high populations of S. calcitrans (> 10 flies per cow) did not affect the number of dairy cows lying down. However, it modified site preferences for lying.
