Can we save large carnivores without losing large carnivore science?

Benjamin L. Allen, Lee R. Allen, Henrik Andrén, Guy Ballard, more

Food Webs > 2017 > 12 > C > 64-75

Large carnivores are depicted to shape entire ecosystems through top-down processes. Studies describing these processes are often used to support interventionist wildlife management practices, including carnivore reintroduction or lethal control programs. Unfortunately, there is an increasing tendency to ignore, disregard or devalue fundamental principles of the scientific method when communicating...

Study design concepts for inferring functional roles of mammalian top predators

Richard M. Engeman, Lee R. Allen, Benjamin L. Allen

Food Webs > 2017 > 12 > C > 56-63

The roles and functions of top predators have in recent years been an important yet controversial field of biodiversity conservation research. Interrelationships between sympatric species within complex systems can pose enormous challenges for designing studies that gain clear understanding of specific relationships and processes. Teasing out the nature of the relationships is made far more difficult,...

Demographic and functional responses of wild dogs to poison baiting

Lee R. Allen

Ecological Management & Restoration > 16 > 1 > 58 - 66

Lethal control of wild dogs – that is Dingo (Canis lupus dingo) and Dingo/Dog (Canis lupus familiaris) hybrids – to reduce livestock predation in Australian rangelands is claimed to cause continental‐scale impacts on biodiversity. Although top predator populations may recover numerically after baiting, they are predicted to be functionally different and incapable of fulfilling critical ecological...

Interactions between two naturalised invasive predators in Australia: are feral cats suppressed by dingoes?

Benjamin L. Allen, Lee R. Allen, Luke K.-P. Leung

Biological Invasions > 2015 > 17 > 2 > 761-776

Top-predators can play important roles in terrestrial food webs, fuelling speculation that top-predators might be used as biocontrol tools against invasive mesopredators. Feral cats are believed to be largely responsible for the current declines of native fauna across tropical northern Australia, where substantial beef cattle production occurs. Dingoes are known to impact cattle production there and...

Evaluating and validating abundance monitoring methods in the absence of populations of known size: review and application to a passive tracking index

Lee R. Allen, Richard M. Engeman

Environmental Science and Pollution Research > 2015 > 22 > 4 > 2907-2915

Rarely is it possible to obtain absolute numbers in free-ranging populations and although various direct and indirect methods are used to estimate abundance, few are validated against populations of known size. In this paper, we apply grounding, calibration and verification methods, used to validate mathematical models, to methods of estimating relative abundance. To illustrate how this might be done,...

Sympatric prey responses to lethal top-predator control: predator manipulation experiments

Benjamin L Allen, Lee R Allen, Richard M Engeman, Luke K-P Leung

Frontiers in Zoology > 2014 > 11 > 1 > 1-30

Introduction Many prey species around the world are suffering declines due to a variety of interacting causes such as land use change, climate change, invasive species and novel disease. Recent studies on the ecological roles of top-predators have suggested that lethal top-predator control by humans (typically undertaken to protect livestock or managed game from predation) is an indirect additional...

Dingoes at the doorstep: Preliminary data on the ecology of dingoes in urban areas

Benjamin L. Allen, Mark Goullet, Lee R. Allen, Allan Lisle, more

Landscape and Urban Planning > 2013 > 119 > Complete > 131-135

Wild carnivores are becoming increasing common in urban areas. In Australia, dingoes exist, in most large cities and towns within their extended range. However, little empirical data is available to inform dingo management or address potential dingo–human conflicts during urban planning. From GPS tracking data, the nine dingoes, predominately juvenile and female, we tracked lived within 700m of residential...

As clear as mud: A critical review of evidence for the ecological roles of Australian dingoes

Benjamin L. Allen, Peter J.S. Fleming, Lee R. Allen, Richard M. Engeman, more

Biological Conservation > 2013 > 159 > Complete > 158-174

Top-predators have been reported to have an important role in structuring food webs and maintaining ecological processes for the benefit of biodiversity at lower trophic levels. This is thought to be achieved through their suppressive effects on sympatric mesopredators and prey. Great scientific and public interest surrounds the potential use of top-predators as biodiversity conservation tools, and...
