Abstract Aim Reducing the impacts of feral cats ( Felis catus ) is a priority for conservation managers across globe, and success in achieving this aim requires detailed understanding species’ ecology broad spectrum climatic environmental conditions. We reviewed diet cat Australia on Australian territorial islands, seeking to identify biogeographical patterns dietary composition diversity, use results consider how may best be managed. Location its islands. Methods Using 49 published...
Context Feral cats (Felis catus) are a threat to biodiversity globally, but their impacts upon continental reptile faunas have been poorly resolved. Aims To estimate the number of reptiles killed annually in Australia by and list Australian species known be cats. Methods We used (1) data from >80 studies cat diet (collectively >10 000 samples), (2) estimates feral population size, model map Key results Australia’s natural environments kill 466 million yr–1 (95% CI; 271–1006 million)....
Abstract Conserving large carnivores is controversial because they can threaten wildlife, human safety, and livestock production. Since often have ranges, effective management requires knowledge of how their ecology functional roles vary biogeographically. We examine continental‐scale patterns in the diet dingo – Australia's largest terrestrial mammalian predator. describe quantify dietary composition diversity with environmental productivity across five bioclimatic zones: arid, semi‐arid,...
Abstract Mammals comprise the bulk of diet free‐ranging domestic cats Felis catus (defined as including outdoor pet cats, strays, and feral cats) in most parts their global range. In Australia, predation by introduced has been implicated extinction many mammal species, ongoing decline extant species. Here, we collate a wide range records (including on Australian mammals model traits extant, terrestrial, native species associated with relative likelihood cat predation. We explicitly seek to...
Feral cats (Felis catus) occur throughout central Australia. In this study, we analysed the stomach contents of 390 feral collected between 1990 and 1994 from southern half Northern Territory. Cats fed on a wide variety invertebrates, reptiles, birds mammals, including animals up to their own body mass in size. Mammals were most important prey but reptiles regularly eaten summer winter. Invertebrates present diet all seasons. Carrion appeared samples during dry winters only has implications...
Abstract There is a paucity of data on the movement patterns feral cats in Australia. Such can be used to refine control strategies and improve track‐based methods monitoring populations cats. In this study home ranges movements male were examined over 3.5 years semiarid woodland environment central Two range estimators examination: (i) minimum convex polygon (MCP); (ii) fixed kernel. The most widely method estimating MCP, while kernel identify core areas within range. On basis MCP method,...
We evaluated the efficacy of spotlight surveys and passive track conducted along roads for assessing relative abundance feral cats dingoes in a semi-arid rangeland environment central Australia. Track were more time-efficient than offered higher precision. cover range issues that need to be considered when using track-based assess population change. also discuss merits other techniques used monitor mammalian carnivores.
Over the last 130 years, patterns of land use in central Australia have altered dramatically, and so too fire regimes management objectives. Although Aboriginal people still tenure over large parts landscape, their lifestyles changed. Most now live towns settlements and, although is culturally important, opportunities for getting out on country to burn are constrained. Large landscape used pastoral production. Under this objective often one exclusion. The other large-scale conservation....
In this paper we utilised a range of data sources to estimate the extent, density distribution and population size feral camel in Australia 2008. Camels currently occupy 3.3 million km2 are spread across much arid Western Australia, South Northern Territory far western Queensland. Up 50% Australia’s rangelands reported as having camels present. The research here supports current minimum for ~1 animals at an overall 0.29 camels/km2. Densities vary, modelling available indicates that two...
Feral camels have significant negative impacts on the environment and social/cultural values of Aboriginal people. These include damage to vegetation through feeding behaviour trampling; suppression recruitment in some plant species; wetlands fouling, trampling, sedimentation; competition with native animals for food, water shelter; sites such as waterholes, that cultural significance people; destruction bushfood resources; reduction people’s enjoyment natural areas; creation dangerous...
Abstract ContextWe recently estimated the numbers of reptiles, birds and mammals killed by cats (Felis catus) in Australia, with these assessments providing further evidence that have significant impacts on Australian wildlife. No previous studies frogs Australia there is limited comparable information from elsewhere world. AimsWe sought to (1) estimate (2) compile a list frog species known be cats. MethodsFor feral cats, we number their frequency occurrence 53 cat dietary (that examined...
Abstract In the present paper, we have provided an initial assessment of current and future threats to biodiversity posed by introduced mammals (predators herbivores) inhabiting Australian rangelands, exploring trends in populations options for management. Notably, rabbits declined recent years wake rabbit haemorrhagic disease, feral camels increased dramatically foxes appear moved northwards, thereby threatening native fauna within expanded range. Following on, developed a framework...
Abstract Competition between red kangaroos and sheep in the more arid areas of Australia was examined by means a large‐scale manipulative experiment incorporating two replicates each three treatments: sheep‐only, kangaroo‐only sheepAangaroo mixture. The study conducted over years during which time pasture conditions varied markedly. intermittent, occurring only period climatically related food depletion (semi‐drought). At this there large increase kangaroo densities due to an influx from...
Abstract Habitat use by feral cats and dingoes was examined within a heterogeneous semi‐arid woodland site in central Australia over 2 years. Density estimates of based on tracks were higher mulga habitat than open habitat. Isodar analysis implied that this pattern consistent with the consumer‐resource model density‐dependent selection, which is an ideal free solution. The reason why supported densities unclear. Foraging success may be because stalk ambush hunting tactics typically employed...
Abstract ContextRecent global concern over invertebrate declines has drawn attention to the causes and consequences of this loss biodiversity. Feral cats, Felis catus, pose a major threat many vertebrate species in Australia, but their effect on invertebrates not previously been assessed. AimsThe objectives our study were (1) assess frequency occurrence (FOO) feral cat diets across Australia environmental geographic factors associated with variation, (2) estimate number consumed by cats...
We conducted a broad-scale aerial survey between 20 August and 12 October 2001 to ascertain the distribution abundance of feral camels in southern part Northern Territory. There was minimum 80 533 Territory at time survey. This figure is corrected for perception bias (a result observers missing animals that are potentially visible), but not availability some being concealed from observers). The population increased mean annual exponential rate, r, 0.093 1993 2001. represents an increase ~10%...
Fracture of the orbital floor is commonly seen in facial trauma. Accurate anatomical reconstruction contour challenging. The authors demonstrate a novel method to more precisely reconstruct on 50-year-old female who sustained an fracture following fall. Results show excellent reapproximation native and complete resolution her enopthalmos asymmetry.
Context Helicopter shooting is an effective tool for reducing feral horse (Equus caballus) populations that are considered overabundant. However, this has been less commonly used in recent years because of concerns about animal-welfare outcomes, which have not previously quantified. Aims The aims the present study were to assess helicopter horses determine (1) duration stress, (2) frequency adverse events and (3) influence explanatory variables determining welfare outcomes. Methods We...
