| the (non)effects of lethal population control on the diet of australian dingoes. | top-predators contribute to ecosystem resilience, yet individuals or populations are often subject to lethal control to protect livestock, managed game or humans from predation. such management actions sometimes attract concern that lethal control might affect top-predator function in ways ultimately detrimental to biodiversity conservation. the primary function of a predator is predation, which is often investigated by assessing their diet. we therefore use data on prey remains found in 4,298 a ... | 2014 | 25243466 |
| mesopredator management: effects of red fox control on the abundance, diet and use of space by feral cats. | apex predators are subject to lethal control in many parts of the world to minimize their impacts on human industries and livelihoods. diverse communities of smaller predators-mesopredators-often remain after apex predator removal. despite concern that these mesopredators may be 'released' in the absence of the apex predator and exert negative effects on each other and on co-occurring prey, these interactions have been little studied. here, we investigate the potential effects of competition and ... | 2017 | 28068378 |
| are we getting the full picture? animal responses to camera traps and implications for predator studies. | camera trapping is widely used in ecological studies. it is often considered nonintrusive simply because animals are not captured or handled. however, the emission of light and sound from camera traps can be intrusive. we evaluated the daytime and nighttime behavioral responses of four mammalian predators to camera traps in road-based, passive (no bait) surveys, in order to determine how this might affect ecological investigations. wild dogs, european red foxes, feral cats, and spotted-tailed qu ... | 2016 | 27096080 |

| dingoes at the doorstep: home range sizes and activity patterns of dingoes and other wild dogs around urban areas of north-eastern australia. | top-predators around the world are becoming increasingly intertwined with humans, sometimes causing conflict and increasing safety risks in urban areas. in australia, dingoes and dingo×domesticdoghybridsarecommoninmanyurbanareas,andposeavarietyofhumanhealth and safety risks. however, data on urban dingo ecology is scant. we gps-collared 37 dingoes in north-easternaustraliaandcontinuouslymonitoredthemeach30minfor11-394days. mostdingoes were nocturnal, with an overall mean home range size of 17.47 ... | 2016 | 27537916 |
| ensemble ecosystem modeling for predicting ecosystem response to predator reintroduction. | introducing a new or extirpated species to an ecosystem is risky, and managers need quantitative methods that can predict the consequences for the recipient ecosystem. proponents of keystone predator reintroductions commonly argue that the presence of the predator will restore ecosystem function, but this has not always been the case, and mathematical modeling has an important role to play in predicting how reintroductions will likely play out. we devised an ensemble modeling method that integra ... | 2017 | 27478092 |
| top-predator control-induced trophic cascades: an alternative hypothesis to the conclusion of colman et al. | colman et al. (2014 proc. r. soc. b 281, 20133094. (doi:10.1098/rspb.2013.3094)) recently argued that observed positive relationships between dingoes and small mammals were a result of top-down processes whereby lethal dingo control reduced dingoes and increased mesopredators and herbivores, which then suppressed small mammals. here, i show that the prerequisite negative effects of dingo control on dingoes were not shown, and that the same positive relationships observed may simply represent wel ... | 2015 | 25473006 |
| human-resource subsidies alter the dietary preferences of a mammalian top predator. | resource subsidies to opportunistic predators may alter natural predator-prey relationships and, in turn, have implications for how these predators affect co-occurring prey. to explore this idea, we compared the prey available to and eaten by a top canid predator, the australian dingo (canis lupus dingo), in areas with and without human-provided food. overall, small mammals formed the majority of dingo prey, followed by reptiles and then invertebrates. where human-provided food resources were av ... | 2014 | 24488213 |
| the short-term effects of a routine poisoning campaign on the movements and detectability of a social top-predator. | top-predators can be important components of resilient ecosystems, but they are still controlled in many places to mitigate a variety of economic, environmental and/or social impacts. lethal control is often achieved through the broad-scale application of poisoned baits. understanding the direct and indirect effects of such lethal control on subsequent movements and behaviour of survivors is an important pre-requisite for interpreting the efficacy and ecological outcomes of top-predator control. ... | 2014 | 24043505 |

| anthropogenic resource subsidies determine space use by australian arid zone dingoes: an improved resource selection modelling approach. | dingoes (canis lupus dingo) were introduced to australia and became feral at least 4,000 years ago. we hypothesized that dingoes, being of domestic origin, would be adaptable to anthropogenic resource subsidies and that their space use would be affected by the dispersion of those resources. we tested this by analyzing resource selection functions (rsfs) developed from gps fixes (locations) of dingoes in arid central australia. using generalized linear mixed-effect models (glmms), we investigated ... | 2013 | 23750191 |
| narrow genetic basis for the australian dingo confirmed through analysis of paternal ancestry. | the dingo (canis lupus dingo) is an iconic animal in the native culture of australia, but archaeological and molecular records indicate a relatively recent history on the continent. studies of mitochondrial dna (mtdna) imply that the current dingo population was founded by a small population of already tamed dogs from southeast asia. however, the maternal genetic data might give a unilateral picture, and the gene pool has yet to be screened for paternal ancestry. we sequenced 14,437 bp of the y- ... | 2012 | 22618967 |
| when does an alien become a native species? a vulnerable native mammal recognizes and responds to its long-term alien predator. | the impact of alien predators on native prey populations is often attributed to prey naiveté towards a novel threat. yet evolutionary theory predicts that alien predators cannot remain eternally novel; prey species must either become extinct or learn and adapt to the new threat. as local enemies lose their naiveté and coexistence becomes possible, an introduced species must eventually become 'native'. but when exactly does an alien become a native species? the dingo (canis lupus dingo) was intro ... | 2012 | 22355396 |
| the predatory behaviour of the thylacine: tasmanian tiger or marsupial wolf? | the extinct thylacine (thylacinus cynocephalus) and the extant grey wolf (canis lupus) are textbook examples of convergence between marsupials and placentals. craniodental studies confirm the thylacine's carnivorous diet, but little attention has been paid to its postcranial skeleton, which would confirm or refute rare eyewitness reports of a more ambushing predatory mode than the pack-hunting pursuit mode of wolves and other large canids. here we show that thylacines had the elbow morphology ty ... | 2011 | 21543392 |
| predator control promotes invasive dominated ecological states. | invasive species are regarded as one of the top five drivers of the global extinction crisis. in response, extreme measures have been applied in an attempt to control or eradicate invasives, with little success overall. we tested the idea that state shifts to invasive dominance are symptomatic of losses in ecosystem resilience, due to the suppression of apex predators. this concept was investigated in australia where the high rate of mammalian extinctions is largely attributed to the destructive ... | 2010 | 20545732 |
| the vector of jaw muscle force as determined by computer-generated three dimensional simulation: a test of greaves' model. | we present results from a detailed three-dimensional finite element analysis of the cranium and mandible of the australian dingo (canis lupus dingo) during a range of feeding activities and compare results with predictions based on two-dimensional methodology [greaves, w.s., 2000. location of the vector of jaw muscle force in mammals. journal of morphology 243, 293-299]. greaves showed that the resultant muscle vector intersects the mandible line slightly posterior to the lower third molar (m3). ... | 2008 | 18838138 |
| computer simulation of feeding behaviour in the thylacine and dingo as a novel test for convergence and niche overlap. | the extinct marsupial thylacine (thylacinus cynocephalus) and placental grey wolf (canis lupus) are commonly presented as an iconic example of convergence. however, various analyses suggest distinctly different behaviours and specialization towards either relatively small or large prey in the thylacine, bringing the degree of apparent convergence into question. here we apply a powerful engineering tool, three-dimensional finite element analysis incorporating multiple material properties for bone ... | 2007 | 17785272 |
| protein structure determination by assembling super-secondary structure motifs using pseudocontact shifts. | computational and nuclear magnetic resonance hybrid approaches provide efficient tools for 3d structure determination of small proteins, but currently available algorithms struggle to perform with larger proteins. here we demonstrate a new computational algorithm that assembles the 3d structure of a protein from its constituent super-secondary structural motifs (smotifs) with the help of pseudocontact shift (pcs) restraints for backbone amide protons, where the pcss are produced from different m ... | 2017 | 28216042 |
| shrub encroachment is linked to extirpation of an apex predator. | the abundance of shrubs has increased throughout earth's arid lands. this 'shrub encroachment' has been linked to livestock grazing, fire-suppression and elevated atmospheric co2 concentrations facilitating shrub recruitment. apex predators initiate trophic cascades which can influence the abundance of many species across multiple trophic levels within ecosystems. extirpation of apex predators is linked inextricably to pastoralism, but has not been considered as a factor contributing to shrub en ... | 2017 | 27918070 |
| contact rates of wild-living and domestic dog populations in australia: a new approach. | dogs (canis familiaris) can transmit pathogens to other domestic animals, humans and wildlife. both domestic and wild-living dogs are ubiquitous within mainland australian landscapes, but their interactions are mostly unquantified. consequently, the probability of pathogen transfer among wild-living and domestic dogs is unknown. to address this knowledge deficit, we established 65 camera trap stations, deployed for 26,151 camera trap nights, to quantify domestic and wild-living dog activity duri ... | 2016 | 27660202 |
| exploring the evolutionary origins of overimitation: a comparison across domesticated and non-domesticated canids. | when learning from others, human children tend to faithfully copy - or 'overimitate' - the actions of a demonstrator, even when these actions are irrelevant for solving the task at hand. we investigate whether domesticated dogs (canis familiaris) and dingoes (canis dingo) share this tendency to overimitate in three experiments. in experiment 1, dogs and dingoes had the opportunity to solve a puzzle after watching an ostensive demonstrator who used both a relevant action and an irrelevant action. ... | 2016 | 27659592 |
| new insights on the history of canids in oceania based on mitochondrial and nuclear data. | how and when dingoes arrived in oceania poses a fascinating question for scientists with interest in the historical movements of humans and dogs. the dingo holds a unique position as top terrestrial predator of australia and exists in a wild state. in the first geographical survey of genetic diversity in the dingo using whole mitochondrial genomes, we analysed 16,428 bp in 25 individuals from five separate populations. we also investigated 13 nuclear loci to compare with the mitochondrial popula ... | 2016 | 27640201 |
| rabies disease dynamics in naïve dog populations in australia. | currently, australia is free from terrestrial rabies but an incursion from nearby indonesia, where the virus is endemic, is a feasible threat. here, we aimed to determine whether the response to a simulated rabies incursion would vary between three extant australian dog populations; free-roaming domestic dogs from a remote indigenous community in northern australia, and free-roaming domestic and wild dogs in peri-urban areas of north-east new south wales. we further sought to predict how differe ... | 2016 | 27544262 |
| concatenation of 'alert' and 'identity' segments in dingoes' alarm calls. | multicomponent signals can be formed by the uninterrupted concatenation of multiple call types. one such signal is found in dingoes, canis familiaris dingo. this stereotyped, multicomponent 'bark-howl' vocalisation is formed by the concatenation of a noisy bark segment and a tonal howl segment. both segments are structurally similar to bark and howl vocalisations produced independently in other contexts (e.g. intra- and inter-pack communication). bark-howls are mainly uttered in response to huma ... | 2016 | 27460289 |

| pattern of nipple use by puppies: a comparison of the dingo (canis dingo) and the domestic dog (canis familiaris). | surprisingly little information is available about the behavior of newborn mammals in the functionally vital context of suckling. we have previously reported notable differences in the pattern of nipple use by kittens of the domestic cat and puppies of the domestic dog. whereas kittens rapidly develop a "teat order," with each individual using principally 1 or 2 particular nipples, puppies show no such pattern. we asked whether the more "chaotic" behavior seen in puppies of the domestic dog (can ... | 2016 | 27135263 |
| deep roots for aboriginal australian y chromosomes. | australia was one of the earliest regions outside africa to be colonized by fully modern humans, with archaeological evidence for human presence by 47,000 years ago (47 kya) widely accepted [1, 2]. however, the extent of subsequent human entry before the european colonial age is less clear. the dingo reached australia about 4 kya, indirectly implying human contact, which some have linked to changes in language and stone tool technology to suggest substantial cultural changes at the same time [3] ... | 2016 | 26923783 |
| unmanned aerial vehicles (uavs) and artificial intelligence revolutionizing wildlife monitoring and conservation. | surveying threatened and invasive species to obtain accurate population estimates is an important but challenging task that requires a considerable investment in time and resources. estimates using existing ground-based monitoring techniques, such as camera traps and surveys performed on foot, are known to be resource intensive, potentially inaccurate and imprecise, and difficult to validate. recent developments in unmanned aerial vehicles (uav), artificial intelligence and miniaturized thermal ... | 2016 | 26784196 |
| the population origins and expansion of feral cats in australia. | the historical literature suggests that in australia, the domestic cat (felis catus) had a european origin [~200 years before present (ybp)], but it is unclear if cats arrived from across the asian land bridge contemporaneously with the dingo (4000 ybp), or perhaps immigrated ~40000 ybp in association with aboriginal settlement from asia. the origin of cats in australia is important because the continent has a complex and ancient faunal assemblage that is dominated by endemic rodents and marsupi ... | 2016 | 26647063 |
| death by sex in an australian icon: a continent-wide survey reveals extensive hybridization between dingoes and domestic dogs. | hybridization between domesticated animals and their wild counterparts can disrupt adaptive gene combinations, reduce genetic diversity, extinguish wild populations and change ecosystem function. the dingo is a free-ranging dog that is an iconic apex predator and distributed throughout most of mainland australia. dingoes readily hybridize with domestic dogs, and in many australian jurisdictions, distinct management strategies are dictated by hybrid status. yet, the magnitude and spatial extent o ... | 2015 | 26514639 |
| interference competition: odours of an apex predator and conspecifics influence resource acquisition by red foxes. | apex predators can impact smaller predators via lethal effects that occur through direct killing, and non-lethal effects that arise when fear-induced behavioural and physiological changes reduce the fitness of smaller predators. a general outcome of asymmetrical competition between co-existing predator species is that larger predators tend to suppress the abundances of smaller predators. here, we investigate interference effects that an apex predator, the dingo (canis dingo), has on the acquisit ... | 2015 | 26296332 |
| a revision of ant-mimicking spiders of the family corinnidae (araneae) in the western pacific. | the corinnidae of the western pacific are revised. the formerly sparassid genus anchognatha thorell, 1881, and the gnaphosid genus battalus karsch, 1878, are transferred to the castianeirinae. the corinninae include only the introduced creugas gulosus thorell, 1878 and medmassa christae sp. nov. from the northern torres strait islands. medmassa pallipes (l. koch, 1873) and medmassa pusilla simon, 1896 are newly synonymised with creugas gulosus. the castianeirinae from the western pacific includi ... | 2015 | 26249225 |
| dingo: differential network analysis in genomics. | cancer progression and development are initiated by aberrations in various molecular networks through coordinated changes across multiple genes and pathways. it is important to understand how these networks change under different stress conditions and/or patient-specific groups to infer differential patterns of activation and inhibition. existing methods are limited to correlation networks that are independently estimated from separate group-specific data and without due consideration of relatio ... | 2015 | 26148744 |
| mesopredator suppression by an apex predator alleviates the risk of predation perceived by small prey. | predators can impact their prey via consumptive effects that occur through direct killing, and via non-consumptive effects that arise when the behaviour and phenotypes of prey shift in response to the risk of predation. although predators' consumptive effects can have cascading population-level effects on species at lower trophic levels there is less evidence that predators' non-consumptive effects propagate through ecosystems. here we provide evidence that suppression of abundance and activity ... | 2015 | 25652837 |
| an ecological regime shift resulting from disrupted predator-prey interactions in holocene australia. | the mass extinction events during human prehistory are striking examples of ecological regime shifts, the causes of which are still hotly debated. in australia, human arrival approximately 50 thousand years ago was associated with the continental-scale extinction of numerous marsupial megafauna species and a permanent change in vegetation structure. an alternative stable state persisted until a second regime shift occurred during the late holocene, when the largest two remaining marsupial carniv ... | 2014 | 24804453 |
| experiments in no-impact control of dingoes: comment on allen et al. 2013. | there has been much recent debate in australia over whether lethal control of dingoes incurs environmental costs, particularly by allowing increase of populations of mesopredators such as red foxes and feral cats. allen et al. (2013) claim to show in their recent study that suppression of dingo activity by poison baiting does not lead to mesopredator release, because mesopredators are also suppressed by poisoning. we show that this claim is not supported by the data and analysis reported in alle ... | 2014 | 24558973 |
| genome sequencing highlights the dynamic early history of dogs. | to identify genetic changes underlying dog domestication and reconstruct their early evolutionary history, we generated high-quality genome sequences from three gray wolves, one from each of the three putative centers of dog domestication, two basal dog lineages (basenji and dingo) and a golden jackal as an outgroup. analysis of these sequences supports a demographic model in which dogs and wolves diverged through a dynamic process involving population bottlenecks in both lineages and post-diver ... | 2014 | 24453982 |

| genetic and morphometric evidence on a galápagos island exposes founder effects and diversification in the first-known (truly) feral western dog population. | domesticated animals that revert to a wild state can become invasive and significantly impact native biodiversity. although dogs can be problematic locally, only the australasian dingo is known to occur in isolation from humans. western dogs have experienced more intense artificial selection, which potentially limits their invasiveness. however, feral dogs eradicated from isabela island, galápagos in the 1980s could be the first-known exception. we used dna and morphometric data from 92 of these ... | 2014 | 24261528 |
| creating a behavioural classification module for acceleration data: using a captive surrogate for difficult to observe species. | distinguishing specific behavioural modes from data collected by animal-borne tri-axial accelerometers can be a time-consuming and subjective process. data synthesis can be further inhibited when the tri-axial acceleration data cannot be paired with the corresponding behavioural mode through direct observation. here, we explored the use of a tame surrogate (domestic dog) to build a behavioural classification module, and then used that module to accurately identify and quantify behavioural modes ... | 2013 | 24031056 |
| looking back at 'looking back': operationalising referential gaze for dingoes in an unsolvable task. | this paper examined the performance of dingoes (canis dingo) on the rope-pulling task, previously used by miklósi et al. (curr biol 13:763-766, 2003) to highlight a key distinction in the problem-solving behaviour of wolves compared to dogs when in the company of humans. that is, when dogs were confronted with an unsolvable task, following a solvable version of the task they looked back or gazed at the human, whereas, wolves did not. we replicated the rope-pulling task using 12 sanctuary-housed ... | 2013 | 23572065 |
| observations of a free-ranging adult female dingo (canis dingo) and littermates' responses to the death of a pup. | in contrast to several species of cetaceans and primates, behavioural responses to dead conspecifics have rarely been reported in wild canids. here we provide details of the responses of an adult female and littermates to a dying and subsequently dead pup, including what appeared to be four instances of transport of the deceased pup by the mother over a two-day period, one of which was directly observed and filmed. we tentatively propose that, in the absence of any evidence of consumption of the ... | 2013 | 23500482 |
