Title mustering of feral horses Type Manuscript
Year Publication Ecology Abbreviated Journal
Volume Issue Pages
Keywords
Abstract Background

Feral horses (Equus caballus) can cause significant environmental damage and losses to

rural industries. Although considered pests, feral horses are also a resource, providing

products such as pet meat for the domestic market and meat for human consumption

for the export market. Control methods include trapping, mustering exclusion fencing,

ground shooting and shooting from helicopters.

Feral horses are mustered by helicopter, motorbike or on horseback, sometimes with the

assistance of coacher horses. Once mustered into yards, net traps or fenced paddocks, the

horses are usually sold to abattoirs for slaughter which can offset the costs of capture and

handling. Less commonly, they are sold as riding horses or relocated to reserves or horse

sanctuaries. Where there is no market for them or where removal may be too costly or

impractical e.g. in conservation areas or remote areas without access to transportation,

horses are sometimes destroyed by shooting in the yards.

This standard operating procedure (SOP) is a guide only; it does not replace or

override the legislation that applies in the relevant State or Territory jurisdiction.

The SOP should only be used subject to the applicable legal requirements (including

OH&S) operating in the relevant jurisdiction.

Title Geometry for mutualistic and selfish herds: the limited domain of danger Type Journal Article
Year 2004 Publication Journal of Theoretical Biology Abbreviated Journal J. Theor. Biol.
Volume 228 Issue 1 Pages 107-113
Keywords Aggregation; Selfish herd; Limited domains
Abstract We present a two-dimensional individual-based model of aggregation behaviour in animals by introducing the concept of a “limited domain of danger”, which represents either a limited detection range or a limited attack range of predators. The limited domain of danger provides a suitable framework for the analysis of individual movement rules under real-life conditions because it takes into account the predator's prey detection and capture abilities. For the first time, a single geometrical construct can be used to analyse the predation risk of both peripheral and central individuals in a group. Furthermore, our model provides a conceptual framework that can be equally applied to aggregation behaviour and refuge use and thus presents a conceptual advance on current theory that treats these antipredator behaviours separately. An analysis of individual movement rules using limited domains of danger showed that the time minimization strategy outcompetes the nearest neighbour strategy proposed by Hamilton's (J. Theor. Biol. 31 (1971) 295) selfish herd model, whereas a random strategy confers no benefit and can even be disadvantageous. The superior performance of the time minimization strategy highlights the importance of taking biological constraints, such as an animal's orientation relative to its neighbours, into account when searching for efficient movement rules underlying the aggregation process.

Title Social learning about predators: does timing matter? Type Journal Article
Year 2005 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 69 Issue 3 Pages 669-678
Keywords
Abstract In Pavlovian conditioning, animals acquire a response to a previously neutral stimulus (conditioned stimulus, CS), such as a light, if that stimulus predicts a biologically important event (unconditioned stimulus, US), such as delivery of food. Learning typically occurs when the CS precedes the US (forward conditioning), and not when the CS follows the US (backward conditioning). In social learning about predators, the predator stimulus is considered to be the CS to which observers acquire avoidance responses after the stimulus has been presented in contiguity with an alarmed demonstrator, the US. We tested the prediction that social learning of response to a predator would occur even if the social alarm cues (the US) appeared before the predatory stimulus (the CS). Carib grackles, Quiscalus lugubris, responded to a familiar predator presented at close range by suppressing alarm calls. Presentation of an unfamiliar avian model (black-and-yellow pigeon) also decreased calling, and this inhibition of calling was enhanced following a training session in which the model stimulus was presented in association with grackle alarm calls. Acquired inhibition of calling was independent of the order of presentation of the model and an alarm chorus. These are the first results to indicate that social acquisition of predator avoidance is not dependent upon a particular temporal relationship between predators and social alarm cues. Evolution may have modified some properties of Pavlovian conditioning to accommodate social learning about potentially dangerous stimuli.

Title Why behaviour patterns that animals learn socially are locally adaptive Type Journal Article
Year 1995 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 49 Issue 5 Pages 1325-1334
Keywords
Abstract Recent models of the social transmission of behaviour by animals have repeatedly led their authors to the counterintuitive (and counterfactual) conclusion that traditional behaviour patterns in animals are often not locally adaptive. This deduction results from the assumption in such models that frequency of expression of socially learned behaviour patterns is not affected by rewards or punishments contingent upon their expression. An alternative approach to analysis of social learning processes, based on Staddon-Simmelhag's conditioning model, is proposed here. It is assumed that social interactions affect the probability of introduction of novel behaviour patterns into a naive individual's repertoire and that consequences of engaging in a socially learned behaviour determine whether that behaviour continues to be expressed. Review of several recently analysed instances of animal social learning suggests that distinguishing processes that introduce behaviour patterns into the repertoires of individuals from processes that select among behavioural alternatives aids in understanding observed differences in the longevity of various traditional behaviour patterns studied in both laboratory and field. Finally, implications of the present approach for understanding the role of social learning in evolutionary process are discussed.

Title A Comparative Study of the Use of Visual Communicative Signals in Interactions Between Dogs (Canis familiaris) and Humans and Cats (Felis catus) and Humans Type Journal Article
Year 2005 Publication Journal of Comparative Psychology Abbreviated Journal J. Comp. Psychol.
Volume 119 Issue 2 Pages 179-186
Keywords
Abstract Dogs' (Canis familiaris) and cats' (Felis catus) interspecific communicative behavior toward humans was investigated. In Experiment 1, the ability of dogs and cats to use human pointing gestures in an object-choice task was compared using 4 types of pointing cues differing in distance between the signaled object and the end of the fingertip and in visibility duration of the given signal. Using these gestures, both dogs and cats were able to find the hidden food; there was no significant difference in their performance. In Experiment 2, the hidden food was made inaccessible to the subjects to determine whether they could indicate the place of the hidden food to a naive owner. Cats lacked some components of attention-getting behavior compared with dogs. The results suggest that individual familiarization with pointing gestures ensures high-level performance in the presence of such gestures; however, species-specific differences could cause differences in signaling toward the human.

Title Roots of brain specializations: preferential left-eye use during mirror-image inspection in six species of teleost fish Type Journal Article
Year 1999 Publication Behavioural Brain Research Abbreviated Journal Behav. Brain. Res.
Volume 106 Issue 1-2 Pages 175-180
Keywords Predator fixation; Fish; Left-eye preference
Abstract It has recently been reported that predator inspection is more likely to occur when a companion (i.e. the mirror image of the test animal) is visible on the left rather than on the right side of mosquitofish Gambusia holbrooki. This very unexpected outcome could be consistent with the hypothesis of a preferential use of the right eye during sustained fixation of a predator as well as of a preferential use of the left eye during fixation of conspecifics. We measured the time spent in monocular viewing during inspection of their own mirror images in females of six species of fish, belonging to different families--G. holbrooki, Xenotoca eiseni, Phoxinus phoxinus, Pterophyllum scalare, Xenopoecilus sarasinorum, and Trichogaster trichopterus. Results revealed a consistent left-eye preference during sustained fixation in all of the five species. Males of G. holbrooki, which do not normally show any social behaviour, did not exhibit any eye preferences during mirror-image inspection. We found, however, that they could be induced to manifest a left-eye preference, likewise females, if tested soon after capture, when some affiliative tendencies can be observed. These findings add to current evidence in a variety of vertebrate species for preferential involvement of structures located in the right side of the brain in response to the viewing of conspecifics.

Title Preliminary study of the development of the Flehmen response in Equus caballus Type Journal Article
Year 2002 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 78 Issue 2-4 Pages 329-335
Keywords Horse behavior; Flehmen; Foal development
Abstract The flehmen response is commonly seen in most ungulates as well as in several other species (e.g. felids). The behavior is most often thought to be part of the sexual behavioral repertoire of males. One reigning hypothesis suggests that this behavior allows the male to determine the estrous state of a female through the chemosensory functions of the vomeronasal organ. However, females and young of both sexes also exhibit this behavior. Horse foals most frequently show the flehmen response during their first month of life with colts showing the behavior more often than fillies. This study tested the flehmen response on male and female foals throughout their pre-pubertal period. Foals were separately presented estrous and non-estrous urine weekly during the first month of life and then monthly until they were approximately 7 months of age. No significant differences were found between male and female foals for the following variables: latency to flehmen, duration of flehmen, frequency of flehmen and sniffs.
